  • The 64 mg and 32 mg doses were not statistically significantly different from placebo at Week 12 on the primary endpoint, the PANSS Marder Negative Symptoms Factor Score (p ≤0.064 and 0.259, respectively), or the key secondary endpoint, the Personal and Social Performance Scale Total Score (p ≤0.021 and p ≤0.542, respectively)
  • Roluperidone separated from placebo on both primary and key secondary endpoints at Weeks 4, 8 and 12
  • Roluperidone was generally well tolerated with a safety profile comparable to placebo

WALTHAM, Mass., May 29, 2020 (GLOBE NEWSWIRE) -- Minerva Neurosciences, Inc. (NASDAQ: NERV), a clinical-stage biopharmaceutical company focused on the development of therapies to treat central nervous system disorders, announced today that the Phase 3 trial of roluperidone to treat negative symptoms in schizophrenia did not meet its primary (reduction in PANSS Marder Negative Symptoms Factor Score or NSFS) and key secondary (improvement in the Personal and Social Performance Scale Total Score or PSP) endpoints.

Trial parameters and top-line results

In total, 515 patients were enrolled into the trial, and 513 patients received treatment and were included in the safety and Intent-To-Treat population. The trial was conducted in the USA, Europe and Israel. There were 172 patients who received placebo, 172 patients who received roluperidone 32 mg, and 171 patients who received roluperidone 64 mg. Demographic and baseline disease characteristics were comparable across all treatment arms.

The results for both roluperidone doses versus placebo across both the primary and the key secondary endpoints to Week 12 were corrected for multiplicity using the truncated Hochberg procedure.

The primary objective of the trial was to evaluate the change from baseline to Week 12 of NSFS with 32 mg and 64 mg doses of roluperidone compared to placebo in patients diagnosed with schizophrenia presenting with moderate to severe negative symptoms. Neither the 32 mg nor 64 mg dose of roluperidone showed a statistically significant separation from placebo (32 mg: p ≤0.256, effect size [ES]=0.1; 64 mg: p ≤0.064, ES=0.2).

Furthermore, neither dose showed a statistically significant separation from placebo on the key secondary endpoint, the change from baseline to Week 12 in PSP (32 mg: p ≤0.542, ES=0.1; 64 mg: nominal p ≤0.021, ES=0.3).

Although limited inferences can be drawn from this data, unadjusted statistically significant separations from placebo were observed in NSFS at Week 4 for both doses (32 mg: nominal p ≤0.036, ES=0.2; 64 mg: nominal p ≤0.007, ES=0.3), and at Week 8 for the 64 mg dose (nominal p ≤0.027, ES=0.3), and the 64 mg dose was statistically significantly different from placebo as measured by change in PSP at all other assessment timepoints (Week 4, nominal p ≤0.005, ES=0.3; Week 8: nominal p ≤0.018, ES=0.3).
