Cupertino, Calif., August 14, 2023 – Reviva Pharmaceuticals Holdings, Inc. (NASDAQ: RVPH) (“Reviva” or the “Company”), a late-stage pharmaceutical company developing new therapies that seek to address unmet medical needs in the areas of central nervous system (CNS), inflammatory and cardiometablolic diseases, today reported financial results for the second quarter ended June 30, 2023 and summarized recent business highlights.

“We continued the momentum this quarter by further bolstering foundational support for the broad application of our new chemical entity brilaroxazine, highlighting a differentiated clinical pharmacology and safety profile at this year’s ASPET annual meeting, and the multifaceted activity and potential to treat inflammatory diseases like psoriasis at the International Societies for Investigative Dermatology (ISID) Meeting, and idiopathic pulmonary fibrosis (IPF) at the annual American Thoracic Society (ATS) international conference,” said Laxminarayan Bhat, Ph.D., Founder, President, and CEO of Reviva. “Brilaroxazine continues to demonstrate a well-tolerated safety profile with a unique potential to improve multiple symptom domains and neuroinflammation in schizophrenia. This upcoming quarter will be an exciting time for Reviva with topline data from our pivotal global RECOVER Phase 3 trial expected in October 2023, potentially leading to significant inflection points in the clinical development of brilaroxazine for schizophrenia and expansion opportunities across other conditions driven by dysfunctional serotonin-dopamine signalling.”

Second Quarter 2023 Financial Results

The Company reported a net loss of approximately $12.4 million, or ($0.55) per share, for the three months ended June 30, 2023, compared to a net loss of approximately $5.3 million, or ($0.29) per share, for the same period in 2022. The increase in net loss was primarily attributable to an increase in research and development expenses of approximately $4.5 million and an increase in general and administrative expenses of approximately $2.1 million for the three months ended June 30, 2023.

As of June 30, 2023, the Company’s cash totaled approximately $11.2 million compared to approximately $18.5 million as of December 31, 2022.

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. 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 improvement of overall drug treatment outcomes using Clinical Global Impression (CGI) scale and 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. 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. 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 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.
