they (ZGEN) have a second poster modeling kinetics based on data from weekly dosing cohorts through week 4 to predict cEVR (a 12 week endpoint).
Just a FWIW - one of the papers on rib in RVR shows data indicating that RVR stinks as an endpoint in retreated relapsers. Not conclusive because of small patient population - but something to keep in mind when evaluating the zgen ph ib data.
