Cocrystal Pharma Reports Second Quarter 2025 Financial Results and Provides Updates on its Antiviral Drug-Development Programs
- Favorable CDI-988 Phase 1 safety and tolerability reported
- Challenge study with CDI-988 as a norovirus preventive and treatment planned later this year
BOTHELL, Wash., Aug. 14, 2025 (GLOBE NEWSWIRE) -- Cocrystal Pharma, Inc. (NASDAQ:COCP) ("Cocrystal" or the "Company") reports financial results for the three and six months ended June 30, 2025, and provides updates on its antiviral product pipeline, upcoming milestones and business activities.
"Preparations are underway for a Phase 1b norovirus challenge study to evaluate our potent, oral antiviral candidate CDI-988 as a prophylaxis and treatment," said Sam Lee, Ph.D., Cocrystal's President and co-CEO. "We are encouraged by the favorable safety and tolerability results from our Phase 1 study with CDI-988. This novel protease inhibitor has the potential to transform how we manage this highly contagious virus, which spreads rapidly in military facilities, cruise ships, nursing homes, hospitals and other confined environments. As a prophylactic treatment, CDI-988 could potentially prevent rapid spread of norovirus outbreaks in close quarters.
"We developed CDI-988 for the treatment of norovirus and coronavirus infections using our proprietary structure-based drug discovery platform technology. We are encouraged by our recent in vitro data demonstrating CDI-988 inhibits newly re-emerging norovirus GII.17 strains that are responsible for the 2024-2025 norovirus outbreaks," added Dr. Lee.
"The absence of any approved norovirus treatments or vaccines creates a substantial market opportunity for Cocrystal," said James Martin, Cocrystal's CFO and co-CEO. "With 685 million global cases annually and a $60 billion worldwide economic impact, norovirus represents one of healthcare's most pressing unmet needs."
Antiviral Product Pipeline Overview
We harness our revolutionary, structure-based drug discovery platform technology to engineer next-generation, broad-spectrum antivirals that precisely disrupt viral replication mechanisms. Unlike traditional approaches, our technology identifies compounds that bind to highly conserved regions of viral enzymes, thereby creating a formidable defense against current viral threats as well as their mutations. By specifically targeting these evolutionary-constrained viral regions, our drug candidates maintain efficacy even as viruses mutate, while simultaneously minimizing off-target interactions that typically lead to adverse side effects. This dual advantage represents a significant breakthrough in antiviral drug development. In addition, our innovative methodology fundamentally transforms the conventional drug discovery paradigm by eliminating the inefficient, resource-intensive cycles of high-throughput compound screening and prolonged hit-to-lead optimization. The result is faster identification of promising candidates with superior resistance profiles and safety characteristics.
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. Currently approved antiviral treatments for influenza are effective but are burdened with significant viral resistance.
Each year there are approximately 1 billion cases of seasonal influenza worldwide, 3-5 million severe illnesses and up to 650,000 deaths. About 8 percent of the U.S. population gets sick from flu each season. In addition to the health risk, influenza is responsible for an estimated $10.4 billion in direct medical costs in the U.S. each year.
- Oral CC-42344 for the treatment of pandemic and seasonal influenza A
- Our novel PB2 inhibitor CC-42344 showed excellent in vitro activity against pandemic and seasonal influenza A strains, as well as strains that are resistant to Tamiflu® and Xofluza®.
- In December 2022 we reported favorable safety and tolerability results from the CC-42344 Phase 1 study.
- In December 2023 we began a randomized, double-blind, placebo-controlled Phase 2a human challenge study to evaluate the safety, tolerability, viral and clinical measurements of CC-42344 in influenza A-infected subjects in the United Kingdom, following authorization from the UK Medicines and Healthcare Products Regulatory Agency (MHRA).
- In May 2024 we completed enrollment in the Phase 2a human challenge study.
- In June 2024 we reported that in vitro studies demonstrated CC-42344 inhibits the activity of the highly pathogenic avian influenza A (H5N1) PB2 protein identified in humans exposed to infected dairy cows.
- In December 2024 we announced a plan to extend the CC-42344 Phase 2a human challenge study due to unexpectedly low influenza infection among study participants.
- In May 2025 we reported that CC-42344 was shown to be active against the highly pathogenic 2024 Texas H5N1 avian influenza strain.
- Inhaled CC-42344 as prophylaxis and treatment for pandemic and seasonal influenza A
- Our preclinical testing showed superior pulmonary pharmacology with CC-42344, including high exposure to drug and a long half-life.
- Dry powder inhalation formulation development and toxicology studies have been completed.
- Influenza A/B program
- Our efforts to develop a preclinical lead of novel influenza replication inhibitors for pandemic and season influenza are ongoing.
Norovirus Program
Norovirus is a common and highly contagious virus that afflicts people of all ages and causes symptoms of acute gastroenteritis including nausea, vomiting, stomach pain and diarrhea, as well as fatigue, fever and dehydration. There is currently no effective treatment or effective vaccine for norovirus, and the ability to curtail outbreaks is limited.
In the U.S., noroviruses are responsible for an estimated 21 million infections annually, including 109,000 hospitalizations, 465,000 emergency department visits and an estimated 900 deaths. The annual burden of norovirus to the U.S. is estimated at $10.6 billion. Noroviruses are responsible for up to 1.1 million hospitalizations and 218,000 deaths annually in children in the developing world.
- Oral pan-viral protease inhibitor CDI-988 for the treatment of noroviruses and coronaviruses
- Our novel, broad-spectrum protease inhibitor CDI-988 is being evaluated as a potential treatment for noroviruses and coronaviruses.
- CDI-988 has shown in vitro pan-viral activity against multiple norovirus strains.
- In May 2023 we announced approval of our application to the Australian regulatory agency for a randomized, double-blind, placebo-controlled Phase 1 study to evaluate the safety, tolerability and pharmacokinetics (PK) of CDI-988 in healthy subjects.
- In August 2023 we announced our selection of CDI-988 as our lead compound for the treatment for noroviruses, in addition to coronaviruses.
- In July 2024 we reported favorable safety and tolerability results from the single-ascending dose cohorts in the Phase 1 study.
- In December 2024 we reported favorable safety and tolerability results from the multiple-ascending dose cohorts of the Phase 1 study and the addition of a high-dose cohort.
- In April 2025 we announced that CDI-988 showed superior broad-spectrum antiviral activity against GII.17 strains, the most prevalent strain in the U.S. and Europe in 2024-2025.
- In August 2025 we presented favorable safety and tolerability Phase 1 data from all CDI-988 doses, including the high-dose 1200 mg cohort, at the 2025 Military Health System Research Symposium (MHSRS).
- We plan to initiate a human challenge Phase 1b study in the U.S. in 2025 to evaluate CDI-988 as a norovirus prophylaxis and treatment.
SARS-CoV-2 and Other Coronavirus Program
By targeting viral replication enzymes and proteases, we believe it is possible to develop effective treatments for all diseases caused by coronaviruses including SARS-CoV-2 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 annually by the end of 2031.
- Oral pan-viral protease inhibitor CDI-988 for the treatment of coronaviruses and noroviruses
- CDI-988 exhibited superior in vitro potency against SARS-CoV-2 and demonstrated a favorable safety profile and PK properties.
- In September 2023 we dosed the first healthy subject in our norovirus/coronavirus CDI-988 study, which is expected to serve as a Phase 1 study for both indications.
- In July 2024 we reported favorable safety and tolerability results from the single-ascending dose cohorts in the Phase 1 study.
- In December 2024 we reported favorable safety and tolerability results from the multiple-ascending dose cohorts of the Phase 1 study and the addition of a high-dose cohort.
- In August 2025 we presented favorable safety and tolerability Phase 1 data from all CDI-988 doses, including the high-dose 1200 mg cohort, at the MHSRS.
