CUPERTINO, Calif., June 22, 2023 — Reviva Pharmaceuticals Holdings, Inc. (NASDAQ: RVPH) (“Reviva” or the “Company”), a clinical-stage pharmaceutical company developing therapies that seek to address unmet medical needs in the areas of central nervous system (CNS), cardiovascular, metabolic, and inflammatory diseases, today announced over 80% of patients have been enrolled in the pivotal Phase 3 RECOVER study evaluating brilaroxazine for the treatment of schizophrenia. Enrollment is ongoing at multiple sites in the United States, Europe, and Asia.
“We are very excited that global enrollment has exceeded 80% in our pivotal Phase 3 trial for serotonin-dopamine stabilizer brilaroxazine in schizophrenia,” said Laxminarayan Bhat, Ph.D., Founder, President, and CEO. “We believe the multifaceted activity of brilaroxazine offers the differentiated potential to improve behavioral symptoms as well as the accompanying neuroinflammation and comorbid symptoms commonly associated with schizophrenia. We believe that brilaroxazine’s compelling pharmacological and safety profile has potential to be a well-tolerated treatment approach for the estimated 24 million people worldwide suffering from schizophrenia. We look forward to reporting topline Phase 3 data in Q3 2023.”
RECOVER is a global Phase 3, randomized, double-blind, placebo-controlled, multicenter study designed to assess the safety and efficacy of brilaroxazine in approximately 400 patients with acute schizophrenia compared to placebo. Brilaroxazine will be administered at fixed doses of 15 mg or 50 mg once daily for 28 days. A 52-week open-label extension study with flexible doses of 15 mg, 30 mg, or 50 mg will further evaluate the long-term safety and tolerability of brilaroxazine in patients with stable schizophrenia. Reviva continues to make progress and is on expected pace with patient enrollment and site initiation in geographically diverse centers across this global clinical study.
About Brilaroxazine
Brilaroxazine is an in-house discovered new chemical entity with potent affinity and selectivity against key serotonin and dopamine receptors implicated in schizophrenia and its comorbid symptoms. In a multinational, multicenter, double-blind Phase 2 study in 234 patients with acute schizophrenia or schizoaffective disorder, brilaroxazine met its primary endpoint, reducing Positive and Negative Syndrome Scale (PANSS) total score and demonstrating statistically significant improvement of overall drug treatment outcomes using Clinical Global Impression (CGI) scale and for secondary endpoints evaluating social functioning, and positive and negative symptoms, and directional improvements for depression and cognition. In this completed Phase 2 study, brilaroxazine met all safety endpoints with no weight gain, no increase in blood sugar and lipids, and no cardiac or endocrine adverse effects compared to placebo. Positive data from a clinical drug-drug interaction (DDI) study investigating the potential effect of CYP3A4 enzyme on brilaroxazine in healthy subjects supports no clinically significant interaction when combined with a CYP3A4 inhibitor. A full battery of regulatory compliant toxicology and safety pharmacology studies has been completed for brilaroxazine. The U.S. Food and Drug Administration (FDA) has agreed to consider a potential superior safety label claim if there is a positive outcome on a relevant endpoint in a pivotal Phase 3 study in patients with schizophrenia. 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 efficacy 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.
