In the Phase II study (NCT03373461), patients (n=112) with IgAN were randomized to placebo or different doses of iptacopan1. The primary endpoint was met with a statistically significant (p=0.038) dose response effect on reduction in proteinuria (as measured by 24-hour urinary protein to creatine ratio [UPCR 24h]) with iptacopan vs. placebo, at 90 days1. At the highest dose of 200mg twice daily a 23% reduction in proteinuria was predicted, compared with placebo, at 90 days1.
P2 data from KDNY shows 48% reduction in proteinuria in 84 days AFFINITY trial Not sure if this data is in combination with an SGLT2 inhibitor
The recently approved FILSPARI shows a similar reduction in proteinuria as KDNY's drug ...but has a boxed warning and a REMS Also The recently approved TARPEYO ( accelerated approval ) had a 27% drop in UPCR and is expected to be priced somewhere between $6k-$12k a month -------------------------------- The above is just from quick notes Correct if necessary . I need to compare with OMER's IgaN data ......but if the interim analysis for KDNY's drug at 36 wks shows close to a 50% drop in UPCR , I expect them to file for accelerated approval with eGFR data to follow
