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

BOTHELL, Wash., March 31, 2025 (GLOBE NEWSWIRE) -- Cocrystal Pharma, Inc. (Nasdaq: COCP) (“Cocrystal” or the “Company”) reports financial results for the 12 months ended December 31, 2024, and provides updates on its antiviral product pipeline, upcoming milestones and business activities.

“Our novel, potent antiviral compounds for norovirus, influenza and coronavirus address critical gaps in global health where effective treatments or vaccines are currently lacking,” said Sam Lee, Ph.D., President and co-CEO of Cocrystal. “We plan to initiate a norovirus human challenge study in the U.S. later this year to evaluate our pan-viral protease inhibitor CDI-988 for the potential treatment and prevention of norovirus infection. The big surge in reported norovirus outbreaks is possibly due to norovirus variants switching from GII.4 to GII.17, as well as increased social gathering after the COVID-19 pandemic. Norovirus is the most common cause of acute gastroenteritis and there are no approved therapeutics or vaccines, making it a compelling target.

“We are optimistic that our oral PB2 inhibitor CC-42344 will have potential as a treatment for seasonal influenza A infection and pandemic avian influenza,” he added. “Following the unexpected low infection rate from the Phase 2a challenge study that precluded us from obtaining meaningful human efficacy data, we plan to continue the influenza challenge study.”

“News coverage in recent months of norovirus and avian flu outbreaks underscore the urgent need for new antiviral solutions,” said James Martin, CFO and co-CEO of Cocrystal. “We are advancing our first- and best-in-class antiviral drug compounds that were designed using our Nobel Prize-winning structure-based technologies for these high-value viral targets that address multibillion-dollar markets.”

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 candidates that target highly conserved regions of the viral enzymes, we seek to develop drugs that are effective against the virus and mutations of the virus, while reducing 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.

• Oral CC-42344 for the treatment of pandemic and seasonal influenza A
  • Our novel PB2 inhibitor CC-42344 showed excellent in vitro antiviral 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 oral 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 human challenge study due to unexpectedly low influenza infection among study participants.
    
    
• 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.
  • We have completed CC-42344 inhalation formulation development and GLP toxicology studies.
    
    
• Influenza A/B program
  
  
  • Our efforts to develop a preclinical lead of novel influenza replication inhibitors are ongoing.

Norovirus Program

Norovirus symptoms can include severe nausea, vomiting and diarrhea. An estimated 685 million cases and an estimated 50,000 child deaths worldwide are attributed to norovirus each year, with an estimated societal cost of $60 billion. By targeting viral replication, we believe it is possible to develop an effective treatment and/or prophylaxis for closed environments for all genogroups of norovirus.

• 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 oral 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 oral CDI-988 in healthy volunteers.
  • In August 2023 we announced our selection of CDI-988 as our lead compound for the oral 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 higher-dose cohort.
  • We expect to report topline results from the high-dose healthy volunteer cohort with CDI-988 in the second quarter of 2025.
  • We plan to initiate a human challenge study in the U.S. in 2025 to evaluate CDI-988 as a norovirus treatment and prophylaxis.
    

SARS-CoV-2 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 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 dual pan-norovirus/pan-coronavirus oral 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 cohort 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 higher-dose cohort.
  • We expect to report topline results from the higher dose cohort in the CDI-988 Phase 1 study in the second quarter of 2025.

2024 Financial Results

Research and development (R&D) expenses for 2024 were $12.5 million, compared with $15.2 million for 2023. The decrease was primarily due to the timing of clinical study costs. General and administrative (G&A) expenses for 2024 were $5.3 million, compared with $6.0 million for 2023, with the $0.7 million decrease primarily due to a reduction of insurance costs and other expenses.

During 2023 the Company received $2.6 million related to litigation with an insurer.

The net loss for 2024 was $17.5 million, or $1.72 per share, compared with the net loss for 2023 of $18.0 million, or $1.87 per share. For 2024 the year over-year-net loss was reduced by $3.1 million exclusive of the $2.6 million received in 2023 noted above.

Cocrystal reported unrestricted cash as of December 31, 2024 of $9.9 million, compared with $26.4 million as of December 31, 2023.
