So enough results are in, and out of embargo so now I can say what I was dying to say at the time, well actually.....
Generic Sofosbuvir + Ledipasvir delivers damn good SVR rates and we repeated a trial Professor Gane did (26/26) with Sof+Led+Riba in GT3 and got 13/13 = 100% SVR - please don't get excited this was in treatment naive low fibrosis GT3 only and the +Riba was essential.
Here is the data: fixhepc.com/forum/media-news/914-easl-sl...-4-svr4-overall.html
Isn't Slide 11 – headed “SOF+LDV+RBV for GT3(Ed Gane 2015)” - a double-edged sword for Prof Gane?
It praises Prof Gane's research by reproducing his results on the use of LDV plus Riba for GT3 (although, in passing, most GT3-ers would, I imagine, prefer SOF + DCV without Riba to SOF + LDV with Riba).
But, on further reflection, it's apparent that this result has been largely, if not completely, achieved through the use on Redemption 1 of the very unlicensed LDV from China and Bangladesh, which Prof Gane has been at pains to warn the world – first in his NZ radio interview, then in his NZ TV interview and again in his piece in the NZ patient group mag - may be substandard and ineffective.
As far as I know, Prof Gane has not withdrawn or qualified his previous remarks about the possible inefficacy of unlicensed ledipasvir or at least of some types of unlicensed ledipasvir.
It's true the Redemption 1 results are at this stage only preliminary and, because of the timeline, are mostly SVR4 not SVR12. Also the EASL slides do not state the precise provenance of the unlicensed ledipasvir used in the trial– was it, for example, buyers' club Chinese Mesochem LDV or Incepta's Twinvir or Beximco's Lesovir-C or some combination of these and, if so, in what proportion? The former could be remedied by the publication of the SVR12 results when they become available. Disclosure of the latter could be very informative and relevant given the uncertainty about the precise scope of Prof Gane's comments.
It seems to be me that some sort of resolution of Prof Gane's thesis about unlicensed ledipasvir would be desirable and that Redemption 1 is the best placed trial to do this. If Prof Gane proves to be right then he needs to be congratulated for alerting the world to the possible dangers of unlicensed ledipasvir or at least of some types of unlicensed ledipasvir. But if he proves to be wrong then perhaps he should be given the opportunity to correct or qualify his previous comments - because uncorrected and unqualified those comments have the potential to be not only damaging to the unlicensed generic industry but also needlessly distressing to those patients who have used unlicensed ledipasvir.
