Janssen sNDA for 6-month Schizophrenia Dosing
Janssen Pharmaceutical has submitted a supplemental NDA for paliperidone palmitate 6-month (PP6M) for treating adults diagnosed with schizophrenia. If approved, PP6M will be the first and only long-acting injectable schizophrenia medication with a twice-yearly dosing regimen, Janssen says. FDA approved a Janssen NDA in 2015 for Invega Trinza (paliperidone palmitate), a three-month long-acting atypical antipsychotic indicated to treat schizophrenia.
The submission is based on data from the Route 6 Study, a randomized, double-blind, non-inferiority Phase 3 global study that enrolled 702 adults living with schizophrenia from 20 countries. “Data showed non-inferior efficacy of PP6M compared to paliperidone palmitate 3-month (PP3M) on the primary endpoint of time to relapse at the end of the 12-month period in both intent-to-treat and per-protocol analysis sets,” the company says. And its safety profile was consistent with previous studies of paliperidone palmitate, it says.
