Paliperidone palmitate (Invega Hafyera)
Marketed by Johnson & Johnson
NCT03345342 · Phase 3 · completed
After an open-label stabilization phase, 702 participants were randomized to six-month or three-month paliperidone palmitate and treated double-blind with matching injections, including placebo injections to preserve masking. The primary endpoint was the clinical outcome of time to relapse, but the registry reports that the median was not estimable in either group and does not provide a p-value or confidence interval, so the result cannot be classified as clearly met or missed.
Perseris
Marketed by Indivior Pharmaceuticals, Inc.
NCT02109562 · Phase 3 · completed
This was a randomized, double-blind, placebo-controlled trial with 354 participants and a clinical primary endpoint measuring change in PANSS total score. The primary endpoint was met for both RBP-7000 doses: PANSS scores improved significantly more than with placebo.
