CUPERTINO, Calif., March 30, 2023 (GLOBE NEWSWIRE) -- 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), respiratory and metabolic diseases, today reported financial results for the full year ended December 31, 2022 and summarized recent business highlights.

“2022 was a transformative year focused on preparing our next-generation treatment brilaroxazine for registrational approval in schizophrenia. In February, we initiated our RECOVER pivotal Phase 3 trial and activated multiple global sites across the United States, Europe, and Asia. We capped off the year with the completion of several clinical and nonclinical prelaunch studies to support our potential NDA submission, including positive clinical drug-drug interaction data reinforcing a differentiated pharmacological and safety profile for brilaroxazine,” said Laxminarayan Bhat, Ph.D., Founder, President, and CEO of Reviva. “In the year ahead, we look to build on this momentum with the anticipated topline Phase 3 RECOVER data mid-year. We are highly encouraged by the broad therapeutic potential of brilaroxazine and continue to explore strategic opportunities to support pipeline expansion into other neuropsychiatric and inflammatory conditions arising from underlying dysfunction in serotonin and dopamine signaling. We believe we are well-positioned to execute on our important near-term milestones.”

About Reviva’s Lead Drug Candidate Brilaroxazine

Brilaroxazine (RP5063) is a 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 improvements 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. 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 pulmonary arterial hypertension (PAH) and idiopathic pulmonary fibrosis (IPF) with mitigation of lung fibrosis and inflammation in translational animal models. Reviva believes brilaroxazine has the potential to delay disease progression in PAH and IPF and intends to develop brilaroxazine for these pulmonary indications. Brilaroxazine has already received Orphan Drug Designation by the U.S. FDA for the treatment of these conditions.
