Cupertino, Calif., May 14, 2024 – 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 reported financial results for the first quarter ended March 31, 2024 and summarized recent business highlights.

“This quarter we made strong progress across our late-stage brilaroxazine program in schizophrenia. Importantly, we gained registrational clarity from the FDA on the requirements for an NDA submission which we are on track to complete in the fourth quarter of 2025,” said Laxminarayan Bhat, Ph.D., Founder, President, and CEO of Reviva. “In 2024, we expect several upcoming catalysts including dosing of the first patient in our registrational RECOVER-2 trial in the second quarter, and topline data from our 1-year OLE trial which will inform on the long-term safety and efficacy of brilaroxazine in the fourth quarter of this year. This is a potentially transformative time for Reviva and we remain focused on our mission to bring brilaroxazine to more patients around the world.”

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. Positive topline data from the global Phase 3 RECOVER-1 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 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 CYP3A4 enzyme on brilaroxazine in healthy subjects supports no clinically significant interaction when combined with a CYP3A4 inhibitor. 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.
