Cupertino, Calif., November 13, 2025 – 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 third quarter ended September 30, 2025 and summarized recent business highlights.

“With the comprehensive clinical and non-clinical data package in hand, we believe brilaroxazine is strongly positioned to meet New Drug Application (NDA) filing requirements and advance toward potential registration for schizophrenia,” said Laxminarayan Bhat, Ph.D., Founder, President, and CEO of Reviva. “The consistent body of evidence for brilaroxazine, from early clinical studies through long-term extension studies, continues to demonstrate broad-spectrum, durable efficacy, a favorable safety profile, and strong long-term adherence with once-daily dosing. We are preparing for a pre-NDA meeting with the Food and Drug Administration (FDA) in the fourth quarter of the year and continue to target a potential NDA submission in the second quarter of 2026. We believe brilaroxazine’s differentiated clinical profile has the potential to redefine treatment expectations in schizophrenia and significantly improve patient outcomes worldwide.”

Clinical Program and Business Highlights

●

European Patent (EP3749324) granted by the European Patent Office (EPO) covering use of brilaroxazine for the treatment of pulmonary fibrosis, including idiopathic pulmonary fibrosis (IPF), adding to Reviva’s existing patent protection in key markets around the world including the United States, China and Japan. Brilaroxazine previously received Orphan Drug Designation from the U.S. FDA for the treatment of IPF in July 2024.

●

Announced a positive full dataset and successful completion of the Company’s Phase 3 RECOVER open-label extension (OLE) 1-year study evaluating the long-term safety, tolerability and efficacy of brilaroxazine in patients with schizophrenia (N=446) in June 2025 and additional analyses in October 2025. A summary of the OLE results is provided here:

Once daily brilaroxazine (pooled 15, 30, and 50 mg, N=159) in patient population completed one year treatment, led to robust broad-spectrum efficacy that was sustained over 1-year including PANSS total score (–18.1), positive symptoms (–5.0), negative symptoms (–4.4), negative symptoms Marder factor (-4.4), general psychopathology (-8.7), personal & social performance (11.3) and CGI-S (-0.8, a ≥1 point improvement in 78% of patients)

No clinically meaningful changes in movement disorder scales used for evaluating motor side effects such as akathisia and extrapyramidal symptoms.

Benign weight gain (~1.5 kg) compared to baseline over 52 weeks (1 year treatment). The weight gain is not dose-dependent and possibly related to lifestyle or diet

Favorable and consistent improvement in lipid profile, and blood sugar levels were comparable to baseline over 52 weeks (1 year) across all 3 dose groups

Not associated with hormonal imbalance and sexual side effects. Elevated prolactin levels reported at the beginning of the study were significantly reduced to normal or near normal in all three dose groups. Improvement in thyroid hormone levels and sexual function reported

No incidence of clinically significant cardiac or gastrointestinal side effects. No incidence of drug induced liver injury (DILI)

Generally well tolerated with a discontinuation rate of 35% after 1-year for pooled doses of brilaroxazine

●	Continuing efforts have aimed at expansion of strong diversified patent portfolio comprising composition of matter and lifecycle management strategies for innovative formulations and method of treatment for different major indications.

●	Completed public equity offering raising gross proceeds of $9.0 million, before deducting placement agent fees and other offering expenses.

●

Presented a poster presentation on negative symptom data for brilaroxazine from the Phase 3 RECOVER double-blind trial in patients with acute exacerbation of schizophrenia, and from the long-term open-label extension trial in clinically stable schizophrenia patients at the Central Nervous System (CNS) Summit in Boston, MA, November 2-5, 2025

●

Scheduled to present a late-breaking poster presentation on the anti-inflammatory biomarker data for brilaroxazine from the Phase 3 RECOVER double-blind trial in patients with acute exacerbation of schizophrenia, and from the long-term open-label extension trial in clinically stable schizophrenia patients at the Society for Neuroscience Annual Meeting in San Diego, CA, November 15-19, 2025

Anticipated Milestones and Events

●	Planned meeting with FDA to discuss brilaroxazine’s path to approval in Q4 2025

●	Potential NDA submission for brilaroxazine in schizophrenia targeted in Q2 2026

●	Investigational new drug application (IND) submission for liposomal-gel formulation of brilaroxazine in psoriasis expected by H2-2026

●	Pursuing partnership opportunities for the development of our pipeline
