Cocrystal Pharma Reports Third Quarter 2024 Financial Results and Provides Updates on its Antiviral Drug-Development Programs

BOTHELL, Wash. (November 13, 2024) – Cocrystal Pharma, Inc. (Nasdaq: COCP) (“Cocrystal” or the “Company”) reports financial results for the three and nine months ended September 30, 2024, and provides updates on its antiviral product pipeline, upcoming milestones and business activities.

“The coming months are critically important to Cocrystal as we expect to report topline results from two ongoing clinical studies with our best-in-class antiviral candidates in major medical indications,” said Sam Lee, Ph.D., President and co-CEO of Cocrystal. “In the Phase 2a influenza A challenge study with our oral PB2 inhibitor CC-42344, we expect to report topline results before year end. Earlier this year, we received feedback from the U.S. Food and Drug Administration (FDA) on a Pre-IND package that improves our clarity on the regulatory path and requirements for the late-stage influenza A clinical study we plan to conduct in the U.S.

“The multiple-ascending dose portion in our Phase 1 pan-norovirus/pan-coronavirus study with oral protease inhibitor CDI-988 is underway and we are on track to report topline results in late 2024 or early 2025,” he added. “We view the development of an effective antiviral for norovirus as a significant opportunity for Cocrystal. There is no approved vaccine or antiviral for norovirus, which is highly contagious and the most common cause of acute gastroenteritis. In in vitro studies, CDI-988 exhibited pan-viral activity against multiple norovirus strains, including the strain that is responsible for major outbreaks.”

“Our significant clinical progress so far this year puts us on track for an active 2025,” said James Martin, CFO and co-CEO of Cocrystal. “I’m pleased to report that based on our currently projected expenditures and our cost-efficient business model, we expect our cash will be sufficient to fund the advancement of our planned development programs through the coming 12 months.”

Antiviral Product Pipeline Overview

We apply our proprietary structure-based drug discovery platform technology for developing broad-spectrum antivirals that inhibit viral replication. By designing and selecting antiviral drug candidates that target the highly conserved regions of the viral enzymes, we seek to develop drugs that are effective against the virus and mutations of the virus, and also reduce off-target interactions that may cause undesirable side effects. Our drug discovery process differs from traditional, empirical medicinal chemistry approaches that often require iterative high-throughput compound screening and lengthy hit-to-lead processes.

Influenza Programs

Influenza is a major global health threat that may become more challenging to treat due to the emergence of highly pathogenic avian influenza viruses and resistance to approved influenza antivirals. Each year there are approximately 1 billion cases of seasonal influenza worldwide, 3-5 million severe illnesses and up to 650,000 deaths. On average, about 8% of the U.S. population contracts influenza each season. In addition to the health risk, influenza is responsible for an estimated $11.2 billion in direct and indirect costs in the U.S. annually.

Norovirus Program

Norovirus is a highly contagious infection and is the most common cause of acute gastroenteritis. Worldwide, norovirus causes about one out of five cases of acute gastroenteritis that leads to diarrhea and vomiting. An estimated 685 million cases and an estimated 50,000 child deaths are attributed to norovirus each year worldwide, with an estimated societal cost of $60 billion. By targeting viral replication, we believe it is possible to develop an effective treatment and/or short-term prophylactic for closed environments for all genogroups of norovirus.

COVID-19 and Other Coronavirus Programs

By targeting viral replication enzymes and proteases, we believe it is possible to develop effective treatments for all diseases caused by coronaviruses including COVID-19 and its variants, Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS). CDI-988 showed potent in vitro pan-viral activity against common human coronaviruses, rhinoviruses and respiratory enteroviruses, as well as against noroviruses. The global COVID-19 therapeutics market is estimated to exceed $16 billion by the end of 2031.

Third Quarter Financial Results

Research and development (R&D) expenses for the third quarter of 2024 were $3.2 million, compared with $4.2 million for the third quarter of 2023, with the decrease primarily due to lower clinical study expenses. General and administrative (G&A) expenses for the third quarters of 2024 and 2023 remained relatively stable at $1.8 million.

The net loss for the third quarter of 2024 was $4.9 million, or $0.49 per share, compared with a net loss for the third quarter of 2023 of $4.2 million, or $0.41 per share, that included a $1.6 million payment to the Company in 2023 for a legal settlement.

Nine Month Financial Results

R&D expenses for the first nine months of 2024 were $10.5 million, compared with $10.9 million for the first nine months of 2023. G&A expenses for the first nine months of 2024 were $4.1 million, compared with $4.6 million for the first nine months of 2023.

The net loss for the first nine months of 2024 was $14.2 million, or $1.40 per share, compared with a net loss for the first nine months of 2023 of $13.5 million, or $1.43 per share.

Cocrystal reported unrestricted cash as of September 30, 2024 of $13.0 million, compared with $26.4 million as of December 31, 2023. Net cash used in operating activities for the first nine months of 2024 was $13.3 million, compared with $11.3 million for the first nine months of 2023. The Company had working capital of $12.3 million and 10.2 million common shares outstanding as of September 30, 2024.
