CUPERTINO, Calif., Nov. 14, 2023 — 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), respiratory and metabolic diseases, today reported financial results for the third quarter ended September 30, 2023 and summarized recent business highlights.

“Our brilaroxazine clinical program continues to advance, and we were pleased to recently announce positive topline results for our global Phase 3 RECOVER trial in adults with schizophrenia. The RECOVER trial 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 compared to placebo,” said Laxminarayan Bhat, Ph.D., Founder, President, and CEO of Reviva. “Importantly, we saw generally consistent, clinically significant efficacy and safety findings across our Phase 2 REFRESH and Phase 3 RECOVER trials further reinforcing brilaroxazine’s competitive profile. We expect to report long-term data from our OLE trial in the fourth quarter of 2024 and initiate a registrational Phase 3 RECOVER-2 trial in the first quarter of 2024, which if successful will help support our planned New Drug Application (NDA) submission to the U.S. Food and Drug Administration (FDA) expected in 2025.”

Recent Business Highlights

• Announced positive topline results and successful completion of Reviva’s pivotal Phase 3 RECOVER trial evaluating the efficacy, safety and tolerability of once-daily brilaroxazine in adults with schizophrenia (October 2023)
  • Trial successfully met its primary endpoint, with brilaroxazine at the 50 mg dose achieving a statistically significant and clinically meaningful 10.1-point reduction in Positive and Negative Syndrome Scale (PANSS) total score compared to placebo (-23.9 brilaroxazine 50 mg vs. -13.8 placebo, p<0.001) at week 4.
  • Brilaroxazine achieved statistically significant and clinically meaningful reductions in all major symptom domains and secondary endpoints at week 4 with the 50 mg dose vs. placebo.
  • The 15 mg dose of brilaroxazine was numerically superior to placebo on the primary endpoint and most secondary endpoints and reached statistical significance on two key secondary endpoints.
  • Generally well-tolerated with a side effect profile comparable to placebo for the 15 and 50 mg doses of brilaroxazine; discontinuation rates for brilaroxazine lower than placebo.
• Over 50% of patients currently enrolled in the 1-year OLE study for brilaroxazine in schizophrenia

Anticipated Milestones and Events

• Topline data from 1-year open-label extension (OLE) trial expected Q4 2024

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 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.
