Recent Business Highlights

Reviva Closed Public Offering Resulting in Gross Proceeds of $34.5 Million

In May, Reviva announced the closing of a successful public offering of $34.5 million in gross proceeds from the financing activities. The transaction was led by well known healthcare institutional investors. The funds will be used primarily to proceed with a pivotal Phase 3 study of brilaroxazine (RP5063) for the treatment of acute and maintenance schizophrenia, and for working capital and other general corporate purposes.

Reviva Added to Russell Microcap® Index

In June, Reviva announced it has joined the broad-market Russell Microcap^® Index at the conclusion of the Russell U.S. Indexes annual reconstitution, which has raised awareness among the investment community at an opportune time, as the Company plans to initiate its pivotal Phase 3 trial in Schizophrenia. Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for active investment strategies. Approximately $9 trillion in assets are benchmarked against Russell’s U.S. indexes. Russell indexes are part of FTSE Russell, a leading global index provider.

Anticipated Events and Targeted Milestones for 2021

• Initiate a pivotal, double-blind Phase 3 study in acute schizophrenia
• Regulatory submissions to the U.S. Food and Drug Administration (FDA) for initiating Phase 2 studies in pulmonary arterial hypertension (PAH) and idiopathic pulmonary fibrosis (IPF)
• Pursue partnership opportunities for the development of our pipeline
• Evaluate grant and other non-dilutive financing opportunities for our product candidates from relevant Federal and State Agencies and Foundations

Second Quarter 2021 Financial Results

The Company reported a net loss of approximately $2.6 million, or $0.23 per share, for the quarter ended June 30, 2021, compared to a net loss of approximately $1.6 million, or $0.58 per share, for the same period in 2020.

Cash provided by financing activities in the second quarter totaled $31.5 million related to the net proceeds from equity financing completed in June 2021.

As of June 30, 2021, the Company’s cash and cash equivalents totaled approximately $35.8 million compared to approximately $0.2 million for the same period in 2020.

Reviva believes that based on the current operating plan and financial resources, the Company’s cash and cash equivalents at the quarter end June 30, 2021 will be sufficient to cover general operating expenses into the second half of 2022.

About Reviva’s Lead Drug Candidate Brilaroxazine (RP5063)
Brilaroxazine (RP5063) is a novel serotonin and dopamine receptor modulator that is being evaluated in diseases characterized by dysfunctional serotonin signaling including neuropsychiatric (e.g. schizophrenia, bipolar disorder, depression and attention deficit hyperactivity disorder) and pulmonary indications (e.g. IPF and PAH). In a successful 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 improvements for secondary endpoints evaluating social functioning, and positive and negative symptoms. A full battery of regulatory compliant toxicology and safety pharmacology studies has been completed for brilaroxazine. Reviva believes that 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. 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.

The Company believes brilaroxazine has the potential to delay disease progression in PAH and IPF. Brilaroxazine has already received Orphan Drug Designation by the U.S. FDA for the treatment of these conditions.
