Dear @availlant, @ThomasTu,

Plz shed some light on this. Is this true?

Dear @Nawab

Yes it is true but it is pegIFN a2b. So no better performance than Pegasys (pegIFN a2a).

Its unfortunate that press releases are worded like this.

Dear @availlant,

How many months this extended Compassionate Access Program of Replicor 2139-Mg will last? On the Replicor website, it is written that the CA program is slated to deliver 36 courses. But i don’t know how many months these 36 courses of Replicor 2139-Mg will take.

  • Published studies of pegylated interferon α-2b (Pegbing / Peg-IFNα-2b) report substantially higher HBsAg-loss rates

  • Published studies of pegylated interferon α-2b (Pegbing / Peg-IFNα-2b) report substantially higher HBsAg-loss rates (often 40–65% in selected cohorts) than historical reports of interferon/NA therapy — especially in patients with low baseline HBsAg and when used as add-on therapy.

At 150 HBsAg

Could you point to some of these studies?

I think this study:

They had very low HBsAg to begin with - many HBV drug regimens in clinical trial show substantial HBsAg loss with patients with low (below 100 IU/ml) levels of HBsAg.

Furthermore, the receiver operating characteristic curve showed baseline HBsAg< 72 IU/mL,

And if I’m not mistaken, the results don’t differ so much from standard pegylated interferon, as shown i.e. in this study:

The overall HBsAg clearance rate was 47%

Are you aware of any studies where participants were not chosen to have very low HBsAg levels?

Great analysis, @mantana!
