CUPERTINO, Calif., May 16, 2022 — 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 reported financial results for the first quarter ended March 31, 2022 and summarized recent business highlights.

“In the first quarter, we continued to advance clinical development of Reviva’s lead asset, brilaroxazine with dosing of the first patient in the pivotal Phase 3 RECOVER study in February to assess the safety and efficacy in patients with schizophrenia,” said Laxminarayan Bhat, Ph.D., Founder, President, and CEO of Reviva. “Since that time, the team has successfully initiated more than a dozen sites across the US, with additional international sites on schedule to launch later this summer in both India and Europe. In early May, we hosted an informative KOL event where experts Leslie Citrome and Larry Ereshefsky provided an overview of unmet medical needs and therapeutic opportunities in schizophrenia and other neuropsychiatric disorders, followed by a Company overview of data supporting the clinical development strategy for brilaroxazine in schizophrenia.”

“While we plan to prioritize our efforts on schizophrenia in the near-term, Reviva is evaluating opportunities in additional chronic neuropsychiatric and pulmonary indications that arise from an underlying dysfunction in serotonin and dopamine signaling,” Dr. Bhat added. “Brilaroxazine has therapeutic potential in indications related to bipolar disorder, major depressive disorder (MDD), attention deficit hyperactive disorder (ADHD), pulmonary arterial hypertension (PAH) and idiopathic pulmonary fibrosis (IPF) and we remain active in seeking various non-dilutive financing opportunities, including partnerships, to explore these indications.”
