The treatment protocols give scientists & doctors a frame-of-reference with which to gauge treatment progress. Even though approved by the FDA and done with clinical trials, our treatment statistics will be recorded and tracted, and possibly used in the future for any further decisions regarding dosage and duration. For example, there is evidence that (in some cases) reducing the Ribavirin dosage because of sx complications is not having a measurable impact on treatment success rates. This suggests that *perhaps* in the future Riba dosage could conceivably be reduced, as a matter of course, from the usual 1200mg/day to maybe 600mg.

Looks like the rule is it has to be a multiple of 4 weeks and the base starts with half the original 48 weeks and goes from there. My dr's comment about some of my anal concerns was that its not exact science. Difficult to study all variables in a trial using humans as subjects. Fruit flies, maybe. That said, I still follow the rules like they are.

I believe these are the time frames they used in the Phase 3 trials which allowed them to get FDA approval. I doubt they can make other time recommendations without doing additional clinical trials for each alternate time proposal.

Hey guys,
I'm just curious how pharmaceutical companies come up with such precise lengths of tx. Does it mean that they give u a little extra just to ensure the success? If not, then what, 27 weeks and 6 days would mean a failure? Not that I want to quit, I'm asking ur opinion because I couldnt find an answer on google what is that "extra factor figure" is. If % of SVR after 28 weeks is about 92, then what it would be after lets say 20 or 24 weeks?
