CUPERTINO, Calif., Nov. 12, 2024 (GLOBE NEWSWIRE) -- Reviva Pharmaceuticals Holdings, Inc. (NASDAQ: RVPH) ("Reviva" or the "Company"), a late-stage pharmaceutical company developing therapies that seek to address unmet medical needs in the areas of central nervous system (CNS), inflammatory and cardiometabolic diseases, today announced an enrollment update to the ongoing 1-year open-label extension (OLE) study evaluating the long-term safety and tolerability of brilaroxazine in patients with schizophrenia.
"We are pleased with the pace of enrollment of our OLE study which includes 108 patients that have completed 12 months of treatment and over 250 patients have completed 6 months of treatment. Importantly, we have collected long-term safety data in 100 patients with one year of treatment which is a requirement for our planned New Drug Application (NDA) submission to the Food and Drug Administration (FDA)," said Laxminarayan Bhat, Ph.D., Founder, President, and CEO of Reviva. "Brilaroxazine continues to be generally well tolerated across patients with acute and stable schizophrenia in the OLE study to date. We now expect to report topline 12-month long-term safety and efficacy data in December of 2024."
RECOVER Trial OLE Enrollment Status Update as of November 12, 2024
- Global trial progressing well
- 108 patients have completed 1-year (12-month) of treatment
- Over 250 patients have completed 6-months of treatment
- Blood and digital biomarkers designed to independently support efficacy
- Long-term safety data from 100 patients who have completed 12 months of treatment is a requirement for brilaroxazine's NDA submission to the FDA
- 12 months long-term safety study to complete in Q1 2025
The RECOVER Trial OLE is a randomized, double-blind, placebo-controlled, multicenter study to assess the efficacy and safety of brilaroxazine at fixed doses of 15 mg or 50 mg, administered once daily for 28 days in subjects with an acute exacerbation of schizophrenia, followed by the long-term safety assessment of brilaroxazine at flexible doses of either 15, 30 or 50 mg administered once daily for 52 weeks in subjects with stable schizophrenia. The OLE study will include both double-blind rollover and de novo subjects with stable schizophrenia.
About Brilaroxazine
Brilaroxazine is an in-house discovered new chemical entity with potent affinity and selectivity against key serotonin and dopamine receptors implicated in the pathophysiology of several conditions including schizophrenia, psoriasis and interstitial lung diseases like pulmonary hypertension, pulmonary arterial hypertension (PAH) and idiopathic pulmonary fibrosis (IPF).
Positive topline data from the global Phase 3 RECOVER trial in schizophrenia demonstrated the trial successfully met all primary and secondary endpoints with statistically significant and clinically meaningful reductions across all major symptom domains including reduction in key proinflammatory cytokines implicated in the pathophysiology of schizophrenia and comorbid inflammatory conditions at week 4 with 50 mg of brilaroxazine vs. placebo, with a generally well-tolerated side effect profile comparable to placebo and discontinuation rates lower than placebo. Positive data from a clinical drug-drug interaction (DDI) study investigating the potential effect of the CYP3A4 enzyme on brilaroxazine in healthy subjects supports no clinically significant interaction when combined with a CYP3A4 inhibitors. Reviva believes that a full battery of regulatory compliant toxicology and safety pharmacology studies has been completed for brilaroxazine. Reviva intends to develop brilaroxazine for other neuropsychiatric indications including bipolar disorder, major depressive disorder (MDD) and attention-deficit/hyperactivity disorder (ADHD).
Additionally, brilaroxazine has shown promising nonclinical activity for inflammatory diseases psoriasis, pulmonary arterial hypertension (PAH) and idiopathic pulmonary fibrosis (IPF) with mitigation of fibrosis and inflammation in translational animal models. Brilaroxazine has already received Orphan Drug Designation by the U.S. FDA for the treatment of PAH and IPF conditions.
