Ipsen Plans Palovarotene NDA After Post Hoc Analysis
Ipsen says it is planning to submit an NDA for palovarotene and its use in treating patients with fibrodysplasia ossificans progressiva (FOP). The submission will be based on data from the MOVE trial, a multicenter Phase 3 study. Earlier, dosing in the trial was paused when futility criteria were met at a pre-specified interim analysis, but a recent post hoc analyses showed the retinoic acid receptor y agonist palovarotene reduced mean annualized new heterotopic ossification (HO) volume in pediatric and adult participants with FOP, Ipsen says. The data were compared with untreated patients from a natural history study over 24 months.
Specifically, the data show that palovarotene-treated patients saw a 62% reduction in mean annualized new HO volume versus untreated patients. Palovarotene safety data were otherwise generally consistent with the known adverse event profile of retinoids, the company says.
It describes FOP as an ultra-rare, genetic disorder that is characterized by HO, formation of bone in soft and connective tissues. Ipsen says HO is permanent and leads to severe functional limitations in joint mobility, progressive and cumulative disability and to shortened life expectancy.
