The treatment is being done through Kaiser Permanente and Kaiser tests for viral load on a monthly basis. They tested at the beginning of treatment and, now that the one month date has passed, they tested again to see if the treatment is having the desired effect.
My viral load at the beginning of treatment was 3,550,000 IU (international units) per milliliter of blood. This is considered a high viral load. Not as high as the first time I went through treatment when it was 15,000,000, but still high. High viral load (anything over 800,0000) was considered to be somewhat more difficult to treat under the old regimen.
After one month of treatment, the test came back at 25 IU per milliliter. That is more than a LOG 5 drop in viral load which is an excellent response to treatment. Here is a post about what Log numbers mean regarding viral load.
In Hep C treatment, any number under 50 IU per ML is considered to be a Sustain Viral Response or SVR which means you are cleared of the virus. In the case of Harvoni treatment, this level of response has to be repeated at the two month test and the 3 month test to be considered successful.
Finally, in order to be considered to be cleared (or in remission) this same low level must be repeated in a test 6 months after treatment is finished. If you are below 50 IU per ML six months later you are considered to be, according to the doctors, in remission. The drug manufacturers, of course, say you are cured.
So, the viral load is currently below the threshold for an SVR which is great news. If this continues for the next two months it will be even better. It certainly makes the headaches and gas easier to deal with.

Puzzling Evidence
Viral Load Blips Up and Then Back Down
What I feared came to pass at the end of December; I did indeed have a viral breakthrough. My viral load blipped up to 430 IU/ml. This is a relatively small number, though it is a log scale rise from the less than 43 that is undetectable.
It happened at the end of the year, during our open enrollment period when I was not sure whether I would still have the same insurance that would allow me to stay at California Pacific Medical Center (CPMC).
It happened while some of my health care team was taking some well-deserved time off from work.
It happened while I was scrambling to make sure I would have continuity in my medications as all my meds were running low. (While we are told at length not to let our prescriptions run low, the insurance companies will not let you renew expensive meds early.)
This led to three decisions about the disease.
One, there was not a follow-up test to determine whether the breakthrough was real or a false positive. No one knew whether I was going to be covered and no one wanted to be out of pocket the expense of a confirmatory test.
Two, Dr. Bzowej decided that it might be best to discontinue treatment. This was the second time I had a viral breakthrough at 24 weeks on two separate types of therapy (the RG7128 test and the Standard of Care therapy). She felt that I might be the sort of patient that needs 3-drug therapy.
Three, I had finally gotten my meds renewed just before my coverage changed and since I had a month’s worth of Interferon and Ribavirin left, I thought that I might as well keep taking it until it was gone. There was also a brief period of time when I thought I would continue at CPMC, so I thought that I should keeping taking it until the monthly test at the end of January and see what was happening.
I kept up my medication schedule through the month. Though by the end of January, I knew that I would not be covered for CPMC after February 1st, I went in for the viral load test anyway. By the time the results came back, my coverage had expired but the Nurse Practitioner at CPMC, bless her heart, called my with the results anyway. I was back to undetectable. Good news but what did that make the December test, true viral breakthrough (not good) or false positive (not bad)? We’ll never know
When I started at Kaiser, they tested my viral load on February 10th. I came back undetectable in that one as well, though they said there was qualitative detection. That means that there is some evidence that there is still viral activity, but it is so low that it cannot be counted. I am not completely sure what that portends as depending on what you read it is either very bad or indeterminate.
I have been keeping to the medication schedule and go in tomorrow for another viral load test. We’ll keep moving forward.
As a final note, the TV show Royal Pains comes back this summer for another season. Write in and let the producers know we want to see more of “Fisherman Jim” so we can follow the course of his treatment for Hepatitis C. I believe he is the only character on a prime-time TV show with Hep C. I hope he recovers well on the show, but given that he is still running a fishing boat while undergoing interferon and ribavirin treatment, he sure makes me feel like a wuss. That’s the magic of television…

A Creeping Sense of Dread
Holiday Stress Equals Erratic Meds
I’ve been in treatment for 57 weeks and have been negative since the end of September, but I am approaching my upcoming viral load test with a great deal of trepidation. The month since the last test has been very difficult. The holidays were not a happy time for my wife and I as there were job problems, family problems and the general high stress levels that the holidays can bring.
The combination of all the stress with my growing inability to concentrate and remember resulted in my missing 3 afternoon doses of my meds during the 10 day period following Christmas. This makes me very edgy as it was the combination of skipped interferon and lowered Ribavirin doses that led to the viral breakthrough that bounced me out of the RO5024048, RG7128 study last June.
In this case, I did not miss any interferon doses, but I did miss 3 partial doses of Ribavirin in a relatively short period of time. This was effectively similar to the lowered Ribavirin doses of late May before the breakthrough. Ribavirin by itself does not seem to have a strong direct antiviral effect on the Hep C virus, but it does contribute a great deal to continuing to hold the virus in check once the interferon has pounded it into undetectability. Therefore reducing the dose, whether deliberately or through simply forgetting to take the drug, can have a significant negative effect on continuing to be undetectable.
The strange thing is that I cannot remember forgetting to take two of the doses (I realize how silly that sounds given the state of my brain by this point but nonetheless…). I can only remember the sick feeling of getting up the next morning, going to take my meds and finding the closed container labeled Monday p.m. that still contained my previous evenings dose. It was bad enough the first time, but two days later on Thursday, exactly the same thing happened. I thought I had done my duty, got up the next morning and found the container with the dose on the table. I knew that it was serious, that I had to stay on schedule and yet I had forgotten again. The thing that knots your stomach is the knowledge that you have screwed up and you can’t go back and make it right. The opportunity to stay on the schedule is gone and the best you can hope for is that it hasn’t compromised your treatment.
Several days later, I missed the third evening dose. This time I figured out what happened and decided that yet another behavior modification was necessary. I went to take my evening dose, sat down and opened the container with the meds in it and then my cell phone rang. It was someone to whom I rent space in my studio so I took the call. It took a while to figure out the problem and by that time I had forgotten to take the dose. However, since I had specifically gone into the room to TAKE the dose, when I thought about it later that evening, I confabulated the memory of actually taking the meds. Again, the increasingly sick feeling in the morning when I found the open but full container on the table. I decided at that point that I would immediately take my doses the moment I thought of them from that point on and it has worked excellently since then. It doesn’t matter if the phone rings, my wife is talking to me or I have to run to the bathroom; when the thought of my evening dose crosses my mind, I get up right then and go take it.
I cannot stress enough the importance of keeping your dosing schedule (your doctors, nurses and everyone else all stress the same thing, so I know I am preaching to the choir). If you have to put signs all over your home, rubber bands on your wrist or tattoo it to your forehead; do whatever it takes to stay on your schedule and not miss a dose.
I hope it doesn’t screw me up, but it was a bad end to last year and a tough start to this one, so I am looking at this test the same way you look at the door into the dark basement in the horror movie – don’t go down there and don’t split up.

Undetectable
There is a certain sort of mild agony that accompanies waiting for medical test results. You want to know the results, but at the same time you don’t want to learn anything negative. It is a feeling of “please let me know the results as quickly as possible, but only if it is good news.” If the results are delayed, the tension slowly increases until you don’t care what the results are; you just want to hear something definite. I was in that holding pattern until yesterday when I finally got the first viral load numbers I have seen in a month. The tension turned to relief when I learned I was back to undetectable.
Finally, after 16 weeks of Standard of Care chemo, I am officially back to where I was after 6 weeks of the RO5024048 study. I have definitely been undetectable (under 43 IU/ml by this test) since October 6th. I may have been undetectable since September 23rd, but that was the test the lab screwed up. This means that, among other things, my liver is getting a break from the tissue damage that occurs while fighting the Hep C virus. It can begin to heal and regenerate once again.
It also means there is now a date certain (as the politicians would say) for the end of my Standard of Care chemotherapy. The hepatologists at California Pacific Medical Center (CPMC) continue interferon and ribavirin therapy for 36 weeks after the patient reaches undetectable level. That means that June 15th, 2011 will be the end of treatment. Now I can start crossing off weeks on my calendar (or maybe I can start carving marks into my desktop for each week completed) until it is over.
This is all based on the fact that I stay undetectable in each test from now until then, but I have even more motivation now to adhere as closely as possible to the “Best Practices” of the chemo regimen. (Sorry for the corporate terminology in the last sentence, but I was at our strategic planning staff meeting today where I was bombarded with bureaucratic mumblespeak up to and including “creating cross-functional workgroup plans”)
I have a deadline. There is real evidence that the interferon and ribavirin regimen is working. I will hold these facts in front of me like talismans whenever the night sweats get too wet, nothing seems worth eating and getting up the steps of the stadium to the cheap seats leaves me exhausted. It is working and there is an end in sight. It was worth the wait to hear those things.

The latest Viral Load Results – Sort of
When I checked the mailbox Saturday, I saw the envelope with my latest test results. Two weeks ago when my last test numbers came in the mail, I did some serious magical thinking. I implored nature to be on my side, I beseeched luck and karma and I chanted to myself all the way into the house. This time, the site of the envelope made me queasy. I was so close to undetectable last time and want so much to finally be undetectable with this test, that fear was the main emotion I felt. I want good news. I want the prize and I don’t know how I will react if the numbers don’t back up what I want to happen.
I take the envelope into the house, tear it open and scan down the page past the white and red blood cell results to the RNA quantitative numbers. There I see this statement: “test cancelled, coding error, resubmitted to LIS.” I have been either in the RO5024048 study or in Standard of Care chemotherapy for 10 months. During that time I have had over 40 separate blood draws with hundreds of tests done on the blood. Never during all that has a test failed, been cancelled or had faulty results. But this week, when I may see the result I have been waiting for since I got bounced out of the study by the viral breakthrough, something was wrong with either the blood or the test. To say it is torture would be an insult to those who have actually undergone torture, but mental agony, yes indeed.
I will call my nurse on Monday to check if the test was redone and there are any updated results, but I have the sickening feeling that I won’t see any updated viral load numbers until the results of the test scheduled for this coming Wednesday come back in a couple of weeks.
When you are in chemotherapy your focus tends to narrow. Test results become the mileposts by which you judge your progress. They are regular points of data that you use to chart the fight against your disease. You have cycles of drug taking, cycles of side effects and cycles of results that mark your life. Missing test results have a serious psychological effect on your treatment in the same way that missing drug doses have a serious physical effect. This was the week I was going to celebrate (or weep with fear that the chemotherapy wasn’t going to be effective). Instead I am left hanging for another two weeks until I find out whether it’s hope or fear.
On the bright side, the Giants won the Western Division today and are going to the post-season. So life really is good after all…

Latest Viral Load Count – So Close…
When I checked the mailbox on the way home from work today, the envelope with my latest test results was there. The other two envelopes were my paycheck and my wife’s paycheck, but I didn’t register that until later. I wasn’t thinking about money. The only thing I was thinking about was whether those results would show my viral load was undetectable.
In situations like these (preparing to open the envelope bearing important news), you find that you’re still mentally a primitve creature. I’m not a god-botherer, as the Brits would say, but as I walked in the house I was chanting to myself, “Yes, this is it. Please be undetectable. Yes, this is the week. Come on, let’s see undetectable results.” I sat down at the kitchen table (okay, it was the table on the back porch but you get the picture), held the envelope, took a deep breath and opened it up.
My viral load numbers since the viral breakthrough have been: 40.000; 10,000; 5,000; 1,500; 990; 310 and 110 IU/ml. I was really hoping that I would get that final bump down but it didn’t quite happen. The number was 60 IU/ml. Undetectable on this test is 43. It’s been 13 weeks since I went back on full interferon dosing after the breakthrough and I’m not quite there yet. Seventeen of those little bits of viral DNA per milliliter are still hanging on in various nooks and crannies of my bloodstream.
Objectively, this is not the best news. The longer it takes you to reach undetectable levels the lower your percentage of having a sustained viral response at the end of your chemotherapy. But I’m going to keep the same attitude that I had at the beginning of the RO5024048 polymerase inhibitor trial just under ten months ago. Back then I refused to believe that I would not get the test drug and would end up in the placebo arm of the trial. Now, I refuse to believe that I will not be one of the 25% or so who obtain an SVR as slower responders.
I’m not as stubborn as my wife’s Irish ancestry allows her to be, but I have my own stubborn Polish fatalism going for me and I’m going to ride it to the finish. Primitive mentality yes, but it’s the only one I have.

A Nice Soft Belly
It turns out that my status as a research study participant who morphed into a standard of care hepatology patient created a bit of a black hole in my medical records. Since all of my records from the study are confidential the hepatology department discovered that even though I was 12 weeks into treatment, they did not have basic paperwork on me. To solve this problem, they brought me in for a meeting with another nurse practitioner, TL, to gather the necessary data. Unfortunately, they did not tell me why I was meeting with her and thus I left my medical history documents at home.
When I arrived, they handed me a twelve page questionnaire detailing my medical history, most of which I can never remember in normal circumstances much less when my brain is in a fog. It worked out well enough in the end as TL and I went through it together and puzzled out the details. It was reassuring as well that when I recounted the timeline of my study participation, dose reductions and subsequent viral breakthrough, TL was firmly convinced that the dose reductions were indeed the cause of the breakthrough. It is powerful reinforcement to hear another experienced person express the opinion that it was not the intractability of the virus that caused the problem, but rather the variability in dosage dictated by the study protocols. It reinforces my optimism going forward through the rest of the treatment.
TL informed me that the rest of the treatment would total nine additional months after I became undetectable. Given the nine months I have been on meds, it will make a total of 18 months of interferon, ribavirin and the other assorted drugs I am taking. It is going to be an even longer grind than I assumed at the beginning of the process lo those many months ago.
My viral load is down to 110 IU/ml. after twelve weeks and I am hoping to see it go undetectable (under 47 IU/ml.) in my next test on the 10th of September. That would put the end of my treatment in June of 2011 when I turn 58. If it works and I am still undetectable six months after the end of treatment, I will have gone from diagnosed to cleared of the virus in three years. A dream perhaps, but it’s the one I am sticking with.
The meeting ended up with TL adding some additional monthly blood draws to my schedule and a brief physical exam. TL checked my legs for swelling, listened to my lungs, checked for any rashes and then palpated my stomach to check for ascites. “Oh, you have a nice soft belly,” commented TL, “no evidence of fluids at all.”
That is the best medical comment I may have ever received. From this point forward, anyone who comments on what is left of my spare tire is going to be told that my medical team has complimented me on my soft belly and far be it for anyone else to criticize its texture. In fact, I am patting it now as I finish this missive, so soft…

Heading Towards Undetectable
As I walked in the door from doing some grocery shopping today I picked up the mail which included my latest set of lab results (10 days old actually, but still the most recent I have). My viral load number is down to 310 IU/ml. Yes! Woohoo, etc.!
Since my viral breakthrough my numbers have run 40,000; 10,000; 5,000; 1500; 990 and now 310. In ten weeks I have achieved a log 2.2 reduction in my viral load. With any luck, my test this Wednesday will put me very close to undetectable.
Yes, it’s getting ahead of myself to think about hitting undetectable (under 47IU/ml by this test method) but optimism is what fuels successful treatment and I remain resolutely optimistic.
So there, the graph is going down, the interferon is hunting out and killing the remnants of the Hepatitis C viral horde that was infesting my body and now I am going to go take some drugs and watch a terrible Sci-Fi channel movie with my wife.
I hope your evening is as exciting as mine…

Standard of Care Pace vs. Research Pace
I just got my latest viral load numbers back from the lab today. The viral load has declined to just a bit over 1500 I.U./ml. I have now achieved a log level reduction in viral load since the peak of the viral breakthrough. This is great news but also points up one of the biggest differences between being on the Standard of Care treatment of interferon and Ribavirin and the research trial treatment of interferon, Ribavirin and Polymerase Inhibitor RO5024048. The Hep C virus is definitely harder to kill on only two drugs instead of three.
My viral load progression on Standard of Care has been:
Week 1: 40,000 IU/ml. (peak number of viral breakthrough)
Week 2: 10,000 IU/ml
Week 5: 5,000 IU/ml
Week 7: 1,500 IU/ml (log 1.6 reduction)
My viral load progression on the Research Trial drug was:
Week 0: 12,900,000 IU/ml.
Week 1: 4,260 IU/ml (log 3.48 reduction)
Week 2: 1,110 IU/ml
Week 4: 195 IU/ml
Week 6: undetectable (log 5.83 reduction)
As you can see, the pace at which the virus is destroyed is much slower (though steady) on the interferon and Ribavirin combination. It has taken 6 weeks to get a log 1.6 reduction from the peak breakthrough number when it only took one week to get a log 3.5 reduction from my pre-trial viral load on the polymerase inhibitor. This has taken some getting used to. You get spoiled on the three drug therapy, especially in the case of the polymerase inhibitor because it does not seem to carry major additional side effects along with it. While I steadily heading towards the log 2 reduction in my viral load needed by week twelve after the breakthrough in order to continue treatment, it seems to be happening in slow motion after the knockout blow the RO5024048 dealt the virus while I was on the three drug combination.
While this may pose a few psychological issues for me to deal with, the overall outlook for the polymerase inhibitor plus interferon and Ribavirin mode of treatment is very good. It definitely deals a hammer blow to the virus and so far, most of the individuals I have talked to who are in the trial (admittedly a very small sample) have not reported serious side effects associated with the RO5024048. Also the addition of a new group to the trial which will receive the drug for 24 weeks instead of the 8-12 weeks we got it indicates that the safety issues are not a major concern and that the drug is promising enough to expand the range of patients eligible. This is all very good news for people both awaiting treatment and considering their treatment options. Another effective tool appears to be on the way in the battle against the Hep C virus.
My viral load progression on Standard of Care has been:
Week 1: 40,000 IU/ml. (peak number of viral breakthrough)
Week 2: 10,000 IU/ml
Week 5: 5,000 IU/ml
Week 7: 1,500 IU/ml (log 1.6 reduction)
My viral load progression on the Research Trial drug was:
Week 0: 12,900,000 IU/ml.
Week 1: 4,260 IU/ml (log 3.48 reduction)
Week 2: 1,110 IU/ml
Week 4: 195 IU/ml
Week 6: undetectable (log 5.83 reduction)

RO5024048 Side Effects Reconsidered
Now that I am out of the study and on the Standard of Care of Interferon and Ribavirin, I have been looking back at the first 8 to 12 weeks of treatment to try to determine whether the RO5024048 polymerase inhibitor had side effects of its own, whether it intensified the side effects of the interferon and Ribavirin or did both.
As I have mentioned before in this post, I believe I received the study drug at the beginning of treatment. My viral load dropped log 3.6 or so during the first week of the drug trial, which is almost unheard of on the standard of care. I have yet to drop a full log number from the peak viral load after my viral breakthrough 5 weeks ago now that I am on Standard of Care treatment. This just reinforces my belief that I was given RO5024048. That said, I do not know either how long I received the study drug, nor the size of the dose I received. I could have received 500 mg for 12 weeks, 1000 mg for 12 weeks, or 1000 mg for 8 weeks. In any case, I believe I received the polymerase inhibitor for either the first 8 weeks or the first 12 weeks of the study.
Looking at the list of side effects from the drugs involved I can draw some conclusions about the variation in them as the study went on.
Nausea: seems about the same throughout the study, mild but occasionally intrusive
Vomiting: only happened once
Diarrhea: definitely more serious at the beginning of the study and gradually disappeared as the study went on
Abdominal Pain: is more noticeable in the past 8 weeks
Anorexia: I don’t believe I had it
Dysgeusia: Didn’t notice it until about 8 weeks into treatment
Dry Mouth & Dyspepsia: consistently present throughout treatment
Anemia: seems worse now that I am on standard of care
Neutropenia: set in about 8 weeks into the study and has been consistently present since
Fatigue: seems a bit better since I have been on only interferon and Ribavirin
Chills: present the first several weeks of the trial has disappeared since
Fever: cyclic with the interferon injection schedule throughout the trial
Muscle Pain: intermittently present throughout treatment up to the present, also a general feeling of muscle weakness and fatigue after exertion
Joint Pain: present during the first few months of the trial not present now
Headache: present throughout the trial, more intense early in the trial and during the past 5 weeks
Rash: Never a big problem, but more noticeable during the first few months
Dizziness: only when taking some of the ancillary drugs
Anxiety: peaked during weeks 12-18
Depression: peaked during weeks 10-18
Insomnia: consistently present throughout treatment
Irritability: very irritable early in the trial, became a problem again in weeks 12-18, not a problem since introduction of antidepressants
Throat Pain: have not had any
Injection Site Redness: has not appeared at any time
Sinus Congestion: tends to occur during the first 4 or 5 days after each interferon injection
Alopecia: Hair loss consistent through first 20 weeks of treatment, has moderated since
Blurred Vision: not specifically noticed, but my close focusing ability deteriorated immediately at the start of the trial and the deterioration has remained
Eye Pain: have consistently had eye pain. It tends to happen when attempting to focus on something relatively close to my eyes. Generally moderates when I relax my eyes and my focus
Blood Sugar Problems: none
Back Pain: tightness occurs within a few days of every interferon injection
Laryngitis: none
Sore Throat: has occurred intermittently since the start treatment
Loss of Concentration: As the treatment progressed, my ability to concentrate noticeably declined at about 2:30 every day
Confusion: my short term memory has declined noticeably since the start of treatment
Liver Problems: I developed a hypothyroid condition starting at about week 10
As I look over the list of side effects I notice only a few that seem like they could be directly related to the RO5024048. Diarrhea is something that was only a problem during the time I was on the test drug. Chills have not really happened since the first 8 weeks either. Fatigue seems to have been amplified a bit by the polymerase inhibitor. Joint pain also seemed to disappear after the first 8-10 weeks of the trial. The rash problem was never more than an annoyance and was more extensive during the first 8 weeks. Irritability was definitely high at the beginning of the trial and has moderated since them, particularly since taking the antidepressants. The vision change happened right away, but I also noticed that there was a bit of change to it when I went back on full interferon doses 5 weeks ago.
Most of these are also side effects of the interferon and Ribavirin so the fact that they have moderated over time might just be that my body acclimated to the drugs. If I had to make the call, I would say that diarrhea, joint pain fatigue and rash were all either caused by or intensified by the RO5024048. It seems that the polymerase inhibitor is an easier to tolerate drug that the protease inhibitors such as Telaprevir and Boceprevir. The research coordinators I talked to all said that the Telaprevir study they had run had been much harder on the patients in terms of side effects (especially rash) than the RO5024048.
Given that it seems to hit the virus like the blitzkrieg hit Poland and that it appears to have a more moderate level of side effects than some of the other new drugs, RO5024048 seems to have a bright future fighting Hepatitis C.

Treatment Update - 5 weeks along in Standard Therapy
My latest viral load test results came back and I have a viral load of just a hair over 5,000 I.U./ml. That is a 3.76 log reduction from the 12,900,00 I registered at the beginning of treatment 29 weeks ago. It also shows a trend in the right direction following the viral breakthrough. My numbers from week 24 going forward are 17,000; 40,000; 10,000 and now 5,000. While the 5,000 number is not yet a truly significant reduction from the peak of my breakthrough viral load, it is getting awfully close.
Two other numbers are showing some change as well. My hemoglobin has dropped to 8.2 from the 11.4 it had climbed to after they reduced my Ribavirin dose to 1000 mg. during the final 6 weeks I was in the research study. My neutrophil count has dropped to 500 in the five weeks since they reinstituted a full dose of interferon. The response to these test results by my hepatologist illustrates clearly the difference in being treated outside of a research study. As I discussed in this post, the researchers running the study need to control, as thoroughly as they possibly can, the drugs that are utilized in the study. One of the primary goals of studies like this, after they determine the drug is effective against the virus, is to determine the side effects and potential dangers of the drug. They know the side effects of the standard of care and by adding only the new drug to the treatment, they can see if it amplifies or minimizes or introduces completely new side effects to the standard treatment. So when presented with test results that show that the research subject has anemia or low neutrophil counts they adjust the doses of the standard of care drugs or the research drugs to determine whether this is what is causing the problems. Unfortunately this can result, as in my case, in reducing the effectiveness of the treatment.
Now that I am being treated outside the research study in the standard of care therapy, they have a panoply of treatments they can use to address the problems and keep me on the full doses of the anti-viral drugs. In my case, the hemoglobin count went down fairly quickly and they put me on folic acid to attempt to build up my red blood cells. When that did not have much effect after about 10 days of taking it and my hemoglobin continued to fall, they prescribed procrit, a drug that directly stimulates red blood cell production. It is a drug that has to be injected once a week under the skin, like the interferon. In doing this for the first time, I tried to inject it into a pinched-up roll of fat on the right side of my belly area and discovered that the skin in that part of my body is like rubber. After trying three times to push the needle through this highly resilient and puncture-resistant patch of skin, I gave up and tried my left side. On that side it went right in and the injection was no problem. I’m thinking of offering the skin on the right side of my spare tire as a new material for bicycle tires. Spare tire tires; alligator skin tires; super skin tires; there has to be some money in selling skin outside the skin industry.
They are also attacking the low neutrophil count by prescribing neupogen another injectable drug that stimulates white blood cell production. I am currently in the process of urgent insurance authorization for that drug and should start using it next week. My wife thinks all this is turning me into a pincushion, as I will now be injecting three different drugs every week. I am also taking levothyroxine to stabilize my thyroid function. The change in thyroid function is also a side effect of the interferon. Luckily, this drug is in pill form and I take it once a day. The three drugs mentioned here are all being taken to enable me to continue taking full doses of interferon and Ribavirin to combat the Hepatitis C virus.
So the drug roster being taken either weekly or daily to fight the Hep C or the side effects of the drugs is:
Pegylated Interferon
Ribavirin
Procrit
Neupogen
Levothyroxine
Celexa
Trazadone
Tramadol
Ativan
The final numbers are not in yet as my nurse AR is working to find the cheapest drugs with the lowest copays but so far it works out to be a bit over $375 per month in copayments. This may go up or down some but if it holds at that number it is about $4500 for the duration of the treatment, assuming no additional drugs are needed.
Considering the only drugs I ever really took up until this time were the occasional course of antibiotics; painkillers after surgery or some muscle relaxants after throwing my back out, this level of involvement with the pharmaceutical industry is a whole new world…

Viral Load and Log Numbers
Viral Load is one of the numbers that folks with Hepatitis C take very seriously. We take it more seriously than we probably should given that the viral load numbers do not directly correlate with whether you are symptomatic, the amount of damage to your liver or the seriousness of the side effects that you may be experiencing. It is, however, the number that is measured to determine the ongoing success of your treatment regimen and to determine in the long run whether you have cleared your body of the virus. Given that, it is followed with a great deal of attention.
The viral load is expressed in the number of copies of the Hep C Virus RNA that are contained in a milliliter (ml) of blood. This is expressed as the number international units (IU) of Hep C RNA per ml. In my case, my viral load number ranged from 3,000,000 IU per ml when I was diagnosed to just slightly below 13,000,000 IU/ml at the onset of treatment.
The changes in viral load that we track during treatment are expressed as logarithmic or log numbers. Log number differences in the amount of virus are differences in amount that are expressed as factors of 10. These log number differences are the numbers that are considered significant in Hepatitis C treatment. Using my case as an example, if 13,000,000 IU/ml is my viral load at the start of treatment, then a drop in viral load to 1,300,000 is a log 1 change. A drop to 130,000 is a log 2 change, to 13,000 is a log 3 change, 1,300 is log 4, 130 is log 5 and going to undetectable, or under 15, is right about a log 6 change in viral load. In treatment, the doctors want to see a log 2 drop in viral load by week 12 or the patient is considered to be non-responsive.
Once we understand that, the changes in viral load that we see at various times during our disease and during treatment and the significance of those changes become easier to understand. For example, the changes in my viral load as I progressed from 3,000,000 to 13,000,000 before starting treatment are actually not significant changes despite the fact that they look like large changes. In order to have a log 1 increase in my viral load, I would have had to see it increase to 30,000,000 and a log 2 increase would mean that I would have had to see a viral load number of 300,000,000 IU/ml. Now that would be a high viral load indeed. Likewise if you had a viral load of 250,000 and saw it jump to 500,000 it would be considered a not significant change in amount even though your viral load doubled.
The same thing applies to watching viral load as it drops. If you have that same 250,000 IU/ml at the beginning of treatment, a log 1 drop would require a change to 25,000 and to achieve the log 2 reduction your doctors will want to see by week 12 you need a drop to 2,500 IU/ml. In order to reach the undetectable level, you would need a drop of somewhat over log 4. In my case, when I went from 13,000,000 to 4,000 after one week of treatment, that was over a log 3.5 drop in viral load. Likewise when I had my viral breakthrough and went from under 15 to 17,000 it was about a log 3.1 increase in my viral load.
Both of these numbers were significant because of the size of the logarithmic change in the amount. When my confirmation breakthrough test came back with a number of 40,000 that was not a significant change from the 17,000 number that signaled my viral breakthrough despite the fact that it doubled. When the first test results I got after going on treatment outside the study came back at 10,000 that was also not a significant change. I was happy to see my number going down, but just to get to a simple log 1 change I would have to drop to 4,000 and the magic log 2 change means I have to drop to 400 IU/ml.
So don’t panic over fluctuations in your viral load numbers that might appear to be quite large if they don’t reach the level of a ten-fold (log 1) change or greater. Even then, it may not be signaling a major change in your illness, but if it doesn’t even reach that level, it probably means little or nothing at all…

Why Did I Continue Treatment…
Somebody asked the other day about what the thought process was that resulted in the decision to continue treatment in the face of a viral breakthrough roughly 6 months after the RO5024048 study began. It’s a good question and thinking about the answer made me thoroughly examine why I did decide to go on. After all, why not take a break after 6 months of side effects and wait for new drugs to come online?
It started with the positive initial results I had in the study. My viral load dropped from 13,000,000 to 4,000 (about a log 3.5 drop) in the first week of the study. That’s a pretty impressive result from 7 days of treatment and I was at 195 after 4 weeks of the study. Since I did not become undetectable (less than 15 which is the limit of the test’s detection) at week 4, I was did not have a Rapid Viral Response (RVR) but rather an Early Viral Response or EVR. An RVR means that in the general statistics of Hep C treatment you have about a 60% chance of clearing the virus (also known as a sustained viral response or SVR). An EVR puts you in the 40% range. While these are the cold hard statistics garnered throughout the history of Hep C treatment, the early results for the experimental drug RO5024048, which I believe I was taking, indicate the possibility of a 70% clearing rate. I was undetectable after my 6th week viral load test which means I reached that stage sometime between the 28th and 42nd day of treatment. For all I know my viral load dropped to undetectable the day after my 4th week test putting me tantalizingly close to the RVR cutoff. Sure it’s whistling past the graveyard to think that, but let me carry some illusions through this process.
Both I am my doctors are fairly well convinced that the viral breakthrough was the result of the dose adjustments in my interferon that were mandated by the research protocols. Treatment outside the study under the Standard of Care for Hep C gives me the opportunity to undergo the course of treatment at the full doses of interferon and Ribavirin. This gives the treatment the best chance of working for me.
I was at an undetectable viral load for somewhere around 18 weeks. During this time, my liver enzymes returned to normal and all my liver tests returned results in the normal range. They tell me that this means the inflammation in my liver has subsided and it has had at least a small window of time to begin a bit of healing. My liver disease was between a stage one and two and giving it time to heal will give me a much longer timeframe for the progress of the damage. If continuing treatment returns me to an undetectable level for another 20 plus weeks, this just can’t be a bad thing for my liver.
All things considered, I tolerate the treatment well. I have side effects and some are worse than others, but compared to the treatment issues that many other patients have it is pretty reasonable. I am continuing to work, albeit at a reduced level of hours. I able to keep what food I eat down through the occasional wave of nausea. The flu-like symptoms follow a reasonably predictable cycle and do not overwhelm me. Insomnia is an ongoing issue, but when it gets particularly intrusive, I have drugs that allow me to sleep without a sedative hangover. The most insidious effect the treatment had on me was the gradual onset of depression. However the deployment of antidepressant medication has made that a manageable issue as well. So if I can tolerate the treatment, why not continue to be aggressive in attacking the virus.
My employment situation is good. Both my boss and the Executive Director of the organization are firmly in my corner and are willing to work with me to create a situation which gives me the best chance to do my job and gives the organization some actual benefit from my continuing to work. There is no guarantee that this level of support will continue indefinitely. Either of the individuals might move on or retire and their replacements might not be as supportive.
My benefits are good. My employer pays for my health plan and the plan I have allows access to the CPMC Hepatology Center which has first-rate doctors and is on the leading edge in both treatment and research. I still have accumulated sick time I can use (though every time I look the number seems to have shrunk a lot more quickly than I thought it would) and my organization allows other employees to donate sick time to me. Luckily, I haven’t alienated everyone in the organization yet and several people (who seem to be frighteningly healthy) have offered to donate time to me. Again, this is the sort of thing you can’t count on being there forever, so why not take advantage of it while I can.
I have a pretty grim view of the financial future of the USA. What with huge deficits and unfunded liabilities; high unemployment, several more years of the housing mess in front of us, the treasury printing trillions of new dollars, the states being for all practical purposes bankrupt, etc, etc, etc, I figure I should go for the treatment while I can afford to do it.
Finally, I have the full support of my wife. She has been absolutely unflinching in her support throughout this process. After we talked about all the reasons for and against continuing, she supported the decision to go ahead and continues to believe along with me, that we are going to beat this virus. After all, it’s not even really alive. It’s just a protein coat with some RNA, damn it and if we can’t even beat something that doesn’t even meet the complete definition of being actually alive, what chance do we have…
It started with the positive initial results I had in the study. My viral load dropped from 13,000,000 to 4,000 (about a log 3.5 drop) in the first week of the study. That’s a pretty impressive result from 7 days of treatment and I was at 195 after 4 weeks of the study. Since I did not become undetectable (less than 15 which is the limit of the test’s detection) at week 4, I was did not have a Rapid Viral Response (RVR) but rather an Early Viral Response or EVR. An RVR means that in the general statistics of Hep C treatment you have about a 60% chance of clearing the virus (also known as a sustained viral response or SVR). An EVR puts you in the 40% range. While these are the cold hard statistics garnered throughout the history of Hep C treatment, the early results for the experimental drug RO5024048, which I believe I was taking, indicate the possibility of a 70% clearing rate. I was undetectable after my 6th week viral load test which means I reached that stage sometime between the 28th and 42nd day of treatment. For all I know my viral load dropped to undetectable the day after my 4th week test putting me tantalizingly close to the RVR cutoff. Sure it’s whistling past the graveyard to think that, but let me carry some illusions through this process.

The Cost of Stress
The results of the first viral load test since I began treatment outside the study came back yesterday and my viral load numbers are trending back down. This is enormously good news. The first test indicating the viral breakthrough showed a viral load of 17,000. The retest number was a touch above 40,000. Now, one month after the initial breakthrough and two weeks after resuming full doses of interferon, the number has dropped to 10,000. This offers confirming evidence for the theory that the breakthrough resulted from the series of reduced and interrupted doses over the final few months of my participation in the study and not because the Hepatitis C virus had begun to develop resistance to interferon. This also adds weight to the belief that it is indeed worthwhile to continue treatment and potentially clear the virus.
Tracing the path of stress during the past month leading up to this result has been a learning experience of the first order. The initial news of the breakthrough brought a tremendous jolt of adrenaline and anxiety. I was convinced the breakthrough had everything to do with the interferon dosing changes due to my low neutrophil counts and was intent on continuing treatment in some form. The uncertainty of whether or not the study doctors and my doctors would agree and what this would mean for ongoing relations with the researchers resulted in a solid seven days of anxiety. The agreement and support of the doctors involved was an all-too-brief relief as the stress shifted to getting rapid treatment and prescription authorizations from the health insurance company and attempting to secure bridge doses of interferon and ribavirin that would allow no further dose interruptions until the prescriptions were filled. Having accomplished that, the stress shifted to finding the best suppliers for the prescriptions which would result in the lowest possible co-payments so as to make ongoing treatment affordable. Finally, the wait for the first round of tests indicating whether the renewal of full-dose interferon treatment would knock the viral load back down continued the grind.
The first 10 days were actually a period of relatively high-energy as news was received, reactions were dealt with, research was done, meetings were planned for, calls were made and decisions were arrived at. The next 10 days were a marathon of waiting for authorizations, arranging prescriptions and deliveries and generally feeling my physical and mental energy drain away. The final days were a series of forced marches through each day. It became hard to sleep and harder to stay awake. I woke up tired, had to take several catnaps a day at my job to be able to keep any mental focus at all and when not at work found myself falling asleep after any activity that required mental effort.
The relief of seeing the new viral load numbers bestowed the great gift of sleeping through the night for the first time in weeks; and sleeping through the following day, and continuing to doze off throughout the day today. Who knows, a few more days of 16 hours of sleep and I might be able to watch the knock-out round of the World Cup with the attention it deserves.

Bad News is Not So Bad 2
The Kindness of Doctors.
All of us who have being living in the American health care system have stories of the system letting people down. Doctors who sleepwalk through their job; insurance companies that find any way possible to deny care; nurses who are surly and hostile; hospitals that warehouse and ignore patients. After a lifetime of these kinds of events, you can become fairly cynical about the motives of healthcare professionals and about their dedication to their jobs and those under their care. The response that has been shown by the folks in the Roche RO5024048 study is the kind of event that can restore your faith in doctors.
In the first phone call to me informing me that I had had a viral breakthrough, AVB the study coordinator told me that I should ask Doctor B, the hepatologist, what she thought about my continuing treatment outside the study protocol. She said there were no guarantees, but I should certainly ask the question. I did not have a lot of confidence in Doctor B’s response. She is the lead doctor on the study. She gets her name on the research paper written about the study and in the interests of gaining research data for the study putting me off-protocol does not help her do that.
When we had our meeting just after the retest blood draws, she went over the viral breakthrough test results and mentioned that, subject to the results of these tests, I would be off the research treatments. AVB mentioned that I had a question for her and I asked about continuing treatment outside the study. Doctor B wanted to look at me test results and most particularly my dosing record. We she examined them in detail and saw that the breakthrough had occurred after 2 skipped doses of interferon due to low neutrophil counts and that I had been on a reduced interferon dose for several weeks before that, her whole personal affect changed. It was a subtle shift from researcher to doctor. She looked closely at my viral load numbers and saw that I had been undetectable for between 12 and 18 weeks even on the reduced dosing and that the dose reductions had all been due to low neutrophil counts (neutropenia). She asked me how I had been handling treatment and the treatment side effects. She told me that outside the research study protocol, she could administer drugs to combat both the neutropenia and the lowered hemoglobin counts. This would allow me to have a good chance to continue treatment on the full doses of interferon and ribavirin, thus giving me the best chance to clear the virus. She mentioned that other drugs were in the pipeline and nearing approval, particularly telaprevir, and did I think I wanted to wait or to continue with treatment now.
I told her I was leaning toward continuing treatment now, but wanted to talk to doctor C, my gastroenterologist before I made my final decision. She immediately told me that she would call him and let him know the latest situation and that I should talk to him and my primary care person as soon as possible so as to be able to get the treatment drug approval process under way with the insurance company as soon as possible. She also volunteered to oversee my treatment if I got a referral to her from my primary care doctor. She also volunteered to call him as well and let him know the situation.
To see the change in view from research scientist to medical doctor determining the best course of care for her patient caught me completely off-guard. It seemed to occur in a matter of an eye-blink. She became completely focused on letting me know the options and the possibilities. It gives me a great deal of confidence in having her as my hepatologist going forward.
My conversation with Doctor C was similar. He wanted to know if I felt I could handle treatment going forward. He also wanted me to know that the percentages of clearing after an event like this are not high. He also emphasized the availability of the drugs to treat the low blood cell counts and the fact that this would allow the higher doses of the Hep C Standard of Care drugs. But the decision is always in my hands.
I am going forward with treatment. It may take a few weeks to get everything set up, but the test results don’t come back until after my usual dosing schedule, so I will have one last dose in my from the Roche study before I forge ahead on my own.
Just as a final note and reality check, I had a meeting with my primary Doctor K. I have some thyroid function issues due to treatment and he needed to prescribe something for that and issue the referral to Doctor B for insurance company purposes. Ah, the reality of being back in the arms of my overworked primary care doctor. Listen, no chance, talk over me, of course, give me confusing instructions, par for the course. It’s good to know something things don’t change…

Bad News Is Not So Bad News 1
The situation of having a viral breakthrough and the decisions made about treatment in light of that breakthrough is a good illustration of the differences between undergoing treatment under the protocols of a drug trial and undergoing treatment under the Standard Of Care supervised by a hepatologist. There is a bit about that is this post.
I met with Doctor B, the doctor in charge of the Roche RO5024048 study today. I was getting the blood tests to confirm that I indeed had a viral breakthrough and met with her as part of that process. Given that it would be highly unusual for the tests to show that I was again undetectable, I am going to be dropped from treatment under the protocols of the study (the protocol is that if you show any viral activity at week 24, treatment is suspended). That being the case, I asked Dr. B what her opinion was of the value of my continuing outside the study using the standard interferon and ribavirin treatment.
She was initially noncommittal and wanted to see my viral load history and my dosing history for the Pegasys and ribavirin. She saw that my viral load had been undetectable for 18 weeks. She also saw that I had spent 5 weeks on a ¾ dose of interferon, had skipped 2 doses completely due to low neutrophil counts and had just resumed injecting at a ½ dose level. I had also been on a reduced dose of ribavirin for the past 7 weeks. When she saw that the breakthrough had occurred after the two skipped doses of interferon, she warmed to the idea. She asked me how I have been tolerating the treatment. I told her I had a lot of the usual side effects but that the addition of an antidepressant had really made a huge difference in my mental outlook and my mental energy. Then she pointed out the reasons she thought it might be worthwhile to pursue.
If you undergo treatment under normal circumstances, you can be prescribed drugs to reduce the loss of neutrophils (neutropenia). You can also be prescribed meds to help with the hemoglobin loss as well. They don’t do this in drug trials because they are trying to control the number of variables as well as to determine the effect the study meds are having with the interference of other drugs. Being able to take these additional medications means that the full doses of interferon and ribavirin can be maintained for the longest possible time during the course of treatment. It goes without saying that this increases the chances for a successful outcome.
In my case for about 40 % of the time I have been in the study, I have been taking reduced doses of just those standard medicines that have proven so successful against Hep C. Moving forward with treatment under full doses means I have a chance to reach a successful outcome. Given the 6 months I have spent on this so far, I don’t see why I shouldn’t grab that chance.

Thoughts From The Nail
The shock of having a viral breakthrough is wearing off. I have spent some considerable time today mulling over the implications of the virus returning. For anyone in this situation, there are a number of considerations and possibilities.
Is there something that presents itself as a reason that the breakthrough might have happened? Does it appear to have happened despite your best efforts to adhere to the protocol? If it happened in spite of you taking all you meds correctly, your virus might be developing a resistance to the type of interferon you are taking or to interferon in general. There is evidence that changing the brand of pegylated interferon you are taking can change the results against the virus. You can talk to your doctor about the possibility of changing the type of interferon you are taking. Of course some insurance plans only include one company’s pegylated interferon in their formulary which means you are out of luck unless you have the $500+ per dose to cover the change.
I believe there was a specific reason for my breakthrough. I think it resulted from dose adjustments made to my interferon dose dictated by the study protocols. These dose adjustments happen to many patients who are undergoing treatment. They are made to attempt to control side effects for the most part. If your hemoglobin drops, if your neutrophil or lymphocyte counts drop too far a dose adjustment will be made in your interferon or ribavirin. In my case, they reduced my Ribavirin dose from 1200 mg to 1000 mg per day after a week 16 retest showed my hemoglobin had dropped to 9.6. I don’t think this had much to do with it. More importantly, at week 21 my neutrophil count went down to 360 and I was told to skip my interferon dose. The next week the count had not rebounded quite far enough and I had to skip another dose. I had only injected one time before my week 24 tests and that was a half dose. I think the suspension of my interferon for two weeks directly contributed to the viral breakthrough.
Which way is you viral load trending? If you have a breakthrough, they are going to retest you to reconfirm that it is a real event. It could be a lab error, especially if it just blips a bit over the undetectable level, or it could be a one-time event. If the results show that your breakthrough is real and the viral load is rising, you’ve probably got a resistant virus and will need to change your treatment drugs or dosing. If your breakthrough is real, but the viral load is declining, then the continuation of your present treatment regimen might mean you will return to the undetectable level. If the results show you are again undetectable, then perhaps it was a test error or one-time event and you can curse the additional gray hair you got while waiting for the results.
Is adjusting your dosing possible? If your breakthrough occurred after lowering your doses of medications, is it possible to raise them again and safely manage the side effects? Did the side effects, especially the blood counts, mean you absolutely had to reduce the dose?
Do you have the option of continuing treatment through your own insurance or by funding it yourself, or is being in a study the only way you can afford treatment?
Does a viral breakthrough mean you are starting over from week one of the 48 week treatment regimen or, if your viral load is trending downward again, would it mean only a continuation to the end of the original treatment time-frame?
All these are questions to ponder. You can endlessly mull them over in your mind right away, or you can try to get away from them for a bit and start to obsess about them when your get your retest results.
I tend more toward the drive yourself crazy by obsessing about them continuously camp. Luckily I have a bunch of drugs to calm me down and help me sleep, otherwise by late next week, I would be a mere husk of myself. Try not to go down that path.
They may have dropped the MPSH on me, but even that bounces after it hits you…

The Million Pound Shit-Hammer
It is week 24 of the experimental trial; half down, half to go.
Current Condition:
Hair - Thin and White
Body - Thinner and White
White Cells - Thin but recovering
Red Cells - Thin but stabilizing.
Brain – Stabilized on Antidepressants
Which, as it turns out is a good thing as I got the news today that I had been dreading. The week 24 tests came back and the Hep C virus is Back.
They call it viral breakthrough (HCV-RNA falls with treatment, but then rises even though treatment is continuing). My latest viral load number is about 17,000 IU per ml.
This means that they will retest next week and if I am not undetectable in that test, they will stop my treatment under the experimental trial protocol. Needless to say, I am encouraging my body to kick it into gear over the next several days. I will have had two additional interferon doses since the original test was performed and I am holding myself optimistic that I will remain on treatment in the trial.
I have already emailed my gastroenterologist, the good Dr. C, asking him for his take on the efficacy of continuing on the Standard Of Care treatment of Pegasys and Ribavirin outside of the trial protocol and will ask the same question of Dr. B. the trial hepatologist when I am tested next week.
We’ll see how it all turns out, but I am definitely not giving up. Hep C is not going to win and I am going to keep fighting it until I clear it from my body.
I am still in shock about the news, so this will be short. I want to explore the implications more soon, but now I just want to watch mindless TV.
As an added note, Wednesday was my birthday. I’ll have to change my age to 57…

I am still in shock about the news, so this will be short. I want to explore the implications more soon, but now I just want to watch mindless TV.
As an added note, Wednesday was my birthday. I’ll have to change my age to 57…

Deciding About Treatment - did I avoid a disaster?
I few posts ago I wrote a bit about Questions you need to think about in regards to treatment.
Let me tell you about the first time I made a decision
It was my second visit to the Gastroenterologist, the fabulous Doctor C. The first visit was relatively brief in that we went over a bit about the disease and he order a full set of labs to determine the genotype of the virus, the viral load and a bunch of liver function tests as well as some general blood work. The primary result of the visit was to realize that I had a great doctor on my side. Doctor C is a warm, supportive personality and also a doctor who Listens. He is not one of those folks who are merely waiting for a chance to talk when he is silent. He listens carefully, gives considered answers and is well versed in the details of the disease. He is not a certified Hepatologist, but he does a great deal of work with coinfected HIV patients and is up on the research and the treatments for Hep C.
The second visit was more detailed as we went over the results of the labs. The bad news was that I had genotype 1 which is the hardest to cure. It is also the one infecting the vast majority of North Americans. My viral load was over 4,000,000 IU per ml. which put me in the category considered to be medium-high viral load. My liver seemed to be in good shape with the various enzyme and function tests not indicating there was much damage. By this time my wife and I had read a great deal about Hep C (interestingly enough for those of you following the progression of side effects, I have forgotten a great deal of that information and have to keep looking stuff up to refresh my memory). We had lots of questions and Doctor C took a great deal of time answering them. Then he asked the fateful question. Do you want to be aggressive in your approach to the disease?
Yes, I replied. He told me that he knew of one of his colleagues currently enrolling a study for a Vertex compound VX-950 (now Telaprevir) and reached for the phone. He caught the doctor in, set up an appointment for two days hence and I was in the process of potentially beginning treatment for the disease. I spent the next 2 days doing research on VX-950. It is a protease inhibitor in phase 3 testing and has a Sustained Viral Response result of 62-64% in trials when it is combined with the Standard of Care (Interferon and Ribavirin). The study in question was an open label phase 3 study wherein every participant got the experimental drug; they were just testing for dosage effects. I admit I had a romantic fantasy about the possibility of being in the study: Man is diagnosed with Hep C on Halloween, goes into treatment in January, finishes treatment in December and is declared clear of the virus under 18 months after being diagnosed. We all have our fantasies, mine are usually not about drugs, but this time they were.
I went to the meeting, learned about the study, was told about the drug and the SOC side effects, signed the papers and went in for the lab tests the next day. It turned out that I showed a thyroid abnormality in my blood tests and there was not enough time to get me retested by the official lab in time to get me into the trial. So close and then the chance for the experimental drug was snatched away. It was particularly painful at the time because there are so few phase 3 tests of promising drugs and so very few tests as well wherein everyone gets the experimental drug and there is no placebo group.
As it turned out, it was probably for the best that I did not make the trial.
The next 3 months were spent in an extremely high-stress situation. My organization was moving an entire portion of its operation into a new space. I had been managing a great deal of the operation for my boss, who was in the middle of number of large projects. In January as the facilities move hit is most vital period, his wife became dangerously ill and they suffered a financial reverse which threatened to wipe out their life savings. I had to step forward and assume control of the entire project and manage it through the actual move and start-up of the new facility. I managed to do it, but the cost to my health was extreme. I was exhausted all the time. I went home from work every day and was capable of merely sitting for a few hours before going to bed. My wife is convinced to this day that the stress load spiked my viral load from the 4,000,000 range to the 6,500,000 number it hit in my next test in June.
If I had been going through treatment, I would never have been able to handle the job that was thrust upon me. I would most likely have collapsed either physically or mentally due to the strain. So, even though I lost the chance to get a late-stage experimental drug which raises SVR rates 40% above the standard of care treatment, my health may be better in the long run for missing the opportunity.
I did not examine all the ramifications of my decision before I made it. That is why it is so important to examine all sides of the issue before you reach a decision. It is hard to go through treatment. Even at its best, it is tiring and depressing and long. So think clearly and try to plan for as many eventualities as you can. It can make the difference between a successful outcome and something potentially very ugly.

Week 10 Tests and Week 8 Results
Today was week 10 testing. All the usual tests though only 11 vials of blood for this series.
The important point to me was the Week 8 test results: viral load UNDECTECTABLE. Unlike week 6 when the test detected viral activity though the number of virus per ml was so low as to be uncountable, this time the test reported no detectable viral activity at all. So there it is, the polymerase inhibitor RG-7128 aka RO5024048 knocked the virus down from just under 13 million per ml to undetectable in 8 weeks.
AVB told me that the earlier a patient achieved the undetectable level, the better the chances are for an SVR (sustained viral response) over the long term. Eight weeks is pretty fast in general and tremendous for someone with my initial viral load. A few of the folks I have talked to about there treatment told me that they started with what was considered a high viral load and theirs was in the 3 to 4 million per ml range. Mine was about 4 times that number at the start of the treatment.
While it does not seem to have added any significant side effects to the general run of the SOC side effects, it doesn’t seem to have reduced any of them either.
The other good news was that my neutrophil count had bounced back up over the 500 level and I could continue the experimental drug. Even though I have hit undetectable levels and there is only 2 weeks left in the polymerase inhibitor part of the experiment, I still want to have the full course of treatment. I want that extra two weeks of this drug completely screwing up the ability of any virus left to reproduce. I want the full amount of destruction to be visited upon this virus. I want them hunted down and killed for as long as possible by the most complete range of attack drugs.
The main new factor to report on the side effect front is that my concentration and memory are continuing to deteriorate. As an example, I did not bring in a chilled urine sample for this test period. Why not, you ask. Because I stepped in to the bathroom after I woke up with my urine collection cup in hand, set it down on the sink and then urinated luxuriously and at length while completely forgetting to get a sample of if for the test. I remembered my test appointment and brought all my stuff with me, but remembering to piss in a cup was more than my brain was capable of.
