• FDA Fast Track designation supports accelerated development and expedites regulatory review
• Norovirus is responsible for an estimated 685 million global cases each year and approximately $60 billion in worldwide economic impact

BOTHELL, Wash., April 02, 2026 (GLOBE NEWSWIRE) — Cocrystal Pharma, Inc. (Nasdaq: COCP) (“Cocrystal” or the “Company”) announces that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation to its oral, direct-acting protease inhibitor, CDI-988, the first oral antiviral candidate being developed for treatment and prophylaxis of norovirus infection.

FDA Fast Track designation aims to facilitate the development and accelerate the review process for drugs that treat serious conditions and address unmet medical needs. The designation enables early and frequent communication with the FDA throughout the development process, allows for rolling review of a New Drug Application (NDA), and may qualify a product for Priority Review at the time of NDA submission.

CDI-988 was designed and developed as an inhibitor of a highly conserved region of noroviruses, coronaviruses, and other 3CL viral proteases. A Phase 1b norovirus challenge study is underway at Emory University School of Medicine to evaluate CDI-988 to both prevent and treat norovirus infection.

“We are pleased that the FDA has granted Fast Track designation for CDI-988, marking a significant milestone for Cocrystal and a critical step toward helping patients with norovirus,” said Sam Lee, Ph.D., President and co‑CEO of Cocrystal Pharma. “Norovirus infections are highly contagious and can cause acute gastroenteritis, resulting in nausea, vomiting, stomach pain, diarrhea, fatigue, fever and dehydration. While most people recover within a few days, immunocompromised individuals can experience chronic, long-term norovirus infections that can persist for weeks to years. Based on compelling data generated to date, we believe that CDI-988 has the potential to both prevent and treat norovirus infection.

“This designation further validates using our unique structure-based drug discovery technology to design pan-viral antivirals that are effective new treatment options,” added Dr. Lee. “We look forward to more frequent interactions with the FDA with the goal of delivering the first therapeutic and preventive medicine to treat norovirus infections.”

• Phase 1b norovirus challenge study is underway at Emory University School of Medicine
• CDI-988 is the first oral antiviral candidate being developed for norovirus treatment and prevention
• No approved treatments or vaccines are available for norovirus infection, posing a significant unmet need and contributing to a global economic burden of $60 billion annually
  

BOTHELL, Wash., March 31, 2026 (GLOBE NEWSWIRE) — Cocrystal Pharma, Inc. (Nasdaq: COCP) (“Cocrystal” or the “Company”) reports financial results for the year ended December 31, 2025, and provides updates on its antiviral product pipeline, upcoming milestones and business activities.

“We are delighted to report that our norovirus human challenge study evaluating efficacy and safety of CDI‑988 is underway at Emory University School of Medicine. In our first cohort, healthy subjects are being inoculated with the GII.2 (Snow Mountain Virus) strain under highly controlled conditions,” said Sam Lee, Ph.D., President and co‑CEO of Cocrystal.

“Norovirus remains a significant and underserved market. Developing an effective norovirus antiviral or vaccine has been challenging due to the high genetic and antigenic diversity of norovirus and lack of simple in vitro cell-based assays and animal model system,” Dr. Lee continued. “Using our proprietary structure‑based drug discovery platform technology, we developed CDI‑988 as a direct‑acting, oral antiviral that targets a highly conserved region of the viral 3CL protease found in all known norovirus strains. As a pan-viral 3CL protease inhibitor, CDI‑988 also holds potential as a broad‑spectrum antiviral effective against coronaviruses.”

“Norovirus outbreaks can strike at any time of year in semi-closed environments such as cruise ships, military settings, and healthcare and assisted-living facilities,” said James Martin, Cocrystal’s CFO and co-CEO. “This constant threat underscores the need for an effective oral treatment and preventive that can be deployed whenever and wherever norovirus infections emerge. With CDI-988, our goal is to provide an easy-to-administer, safe and effective drug to combat these unpredictable outbreaks. We believe CDI‑988 represents a key value-creating opportunity for our Company and our investors.”

The Phase 1b randomized, double-blind, placebo-controlled study will enroll up to 40 subjects. The study’s primary endpoint is efficacy in reducing the incidence of clinical symptoms; secondary endpoints include reduction of viral shedding and disease severity, and safety and pharmacokinetic profiles.

Antiviral Product Pipeline Overview

We leverage our innovative structure-based drug discovery platform technology to develop next-generation, broad-spectrum antivirals that effectively block viral replication. Unlike other drug discovery approaches, our technology identifies compounds that bind to highly conserved regions of viral drug targets, including proteases and replication enzymes. By specifically targeting these essential viral functions, 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.

Norovirus Program
Norovirus is a common, 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 are currently no effective treatments or vaccines for norovirus, and the ability to curtail outbreaks is inadequate.

With 685 million global cases annually and a $60 billion worldwide economic impact, norovirus represents one of healthcare’s most pressing unmet needs. In the U.S., noroviruses are responsible for an estimated 21 million infections annually, including an estimated 109,000 hospitalizations, 465,000 emergency department visits and 900 deaths. The annual burden of norovirus to the U.S. is estimated at $10.6 billion. In the developing world, each year noroviruses are responsible for up to 1.1 million hospitalizations and 218,000 pediatric deaths.

Oral protease inhibitor CDI-988 for the treatment of noroviruses and coronaviruses: Our novel, broad-spectrum 3CL protease inhibitor CDI-988 is designed as a potential treatment for noroviruses and coronaviruses. CDI-988 has shown in vitro activity against multiple norovirus strains.

• In April 2025 we announced that CDI-988 showed superior broad-spectrum antiviral activity against the norovirus GII.17 strain, the most prevalent strain in the U.S. and Europe in 2024-2025.
• In August 2025 we presented favorable Phase 1 safety and tolerability data from all CDI-988 doses, including a high-dose 1200 mg cohort, at the 2025 Military Health System Research Symposium (MHSRS).
• In September 2025 we discussed CDI-988’s scientific foundation and clinical progress in an oral presentation at the 9^th International Calicivirus Conference, the leading calicivirus scientific meeting.
• In September 2025 we received a Study May Proceed Letter from the FDA to conduct a Phase 1b challenge study in the U.S. evaluating CDI-988 as a norovirus preventive and treatment.
• In March 2026 we enrolled the first subjects in our Phase 1b challenge study with the initial cohort evaluating the infectivity rate of the GII.2 challenge inoculum, and subsequent cohorts to be orally administered CDI-988 or placebo.
  

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 approximately 1 billion cases of seasonal influenza, 3-5 million severe illnesses and up to 650,000 deaths are reported worldwide. About 8% 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.

CC-42344 is our novel PB2 inhibitor that showed excellent in vitro activity against pandemic and seasonal influenza A strains, as well as against strains that are resistant to Tamiflu^® and Xofluza^®.

• Oral CC-42344 as a treatment for pandemic and seasonal influenza A
  • In December 2022 we reported favorable Phase 1 safety and tolerability results.
  • In December 2023 we began a randomized, double-blind, placebo-controlled Phase 2a human challenge study to evaluate the safety, tolerability, and 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.
  • In May 2025 we reported that CC-42344 was shown to be active against the highly pathogenic 2024 Texas H5N1 avian influenza strain.
  • In November 2025 an initial Phase 2a study was completed, with CC-42344 showing a favorable safety and tolerability profile with no serious adverse events and no drug-related discontinuations by study participants. Efficacy analyses were not reported due to issues with trial conduct.
  • We plan to continue development of oral CC-42344 as a treatment for pandemic and seasonal influenza A with an additional Phase 2a study.

• 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 developed a dry powder inhalation formulation and have completed toxicology studies.
    
• Influenza A/B program
  
  • In October 2025 we received a $500,000 Small Business Innovation Research Phase I award from the NIH’s National Institute of Allergy and Infectious Diseases to support the development of a novel, broad-spectrum lead candidate targeting the influenza A/B polymerase complex.
    

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. CDI-988 showed potent in vitro pan-viral activity against common human coronaviruses, rhinoviruses and respiratory enteroviruses, as well as against noroviruses. By the end of 2031, the global COVID-19 therapeutics market is estimated to exceed $16 billion annually.

Oral 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 pharmacokinetic properties.

• In August 2025 we presented favorable safety and tolerability Phase 1 data from all CDI-988 doses, including a high-dose 1200 mg cohort, at the MHSRS.
• We are currently pursuing further development of CDI-988 as a prophylaxis and treatment for norovirus and remain optimistic about its viability as a treatment for coronaviruses.
  

2025 Financial Results

• Subject enrollment expected to begin in Q1 2026
• CDI-988 is the first oral broad-spectrum antiviral drug candidate for potential prevention of norovirus outbreaks and treatment of acute viral gastroenteritis caused by norovirus infection
• There are no approved treatments or vaccines currently available for norovirus infection

BOTHELL, Wash., Dec. 18, 2025 (GLOBE NEWSWIRE) — Cocrystal Pharma, Inc. (Nasdaq: COCP) (“Cocrystal” or the “Company”) announces the approval from the Institutional Review Board (IRB) at Emory University School of Medicine to initiate a Phase 1b human challenge study with CDI-988. This study aims to evaluate CDI-988 as both a preventive and treatment for norovirus infections. Initial screening of study subjects is currently underway, with enrollment expected to begin in the first quarter of 2026. The IRB approval from Emory University School of Medicine follows Cocrystal’s prior regulatory milestones, including U.S. Food and Drug Administration (FDA) clearance of its investigational New Drug (IND) application.

CDI-988 is the first oral antiviral drug candidate developed for the prevention and treatment of norovirus acute gastroenteritis. It was specifically designed as a broad-spectrum inhibitor by targeting a highly conserved region of the viral 3CL protease of all noroviruses, including GII.4 and recently re-emerging GII.17.

The randomized, double-blind, placebo-controlled Phase 1b study will be conducted at Emory University and involve up to 40 healthy subjects ages 18-49. Participants will be screened and infected with the norovirus GII.2 (Snow Mountain Virus). The study’s primary efficacy endpoint is to assess the reduction in incidence of clinical symptoms, while the secondary efficacy endpoint focuses on the reduction in viral shedding and disease severity. The study will also assess the safety and pharmacokinetic profile of CDI-988. Additional information is available on clinicaltrials.gov.

“This approval from the Emory IRB marks a significant milestone in advancing our Phase 1b norovirus challenge study,” said Sam Lee, Ph.D., Cocrystal’s President and co-CEO. “We are very excited about collaborating with the Emory team, given their exceptional expertise in norovirus and experience in human challenge studies.

“Cocrystal’s norovirus challenge study is a critical step in addressing the global burden of norovirus outbreaks, which account for an estimated 700 million cases each year worldwide. We are committed to delivering innovative medicine for norovirus outbreaks and chronic norovirus infection among immunocompromised patients,” added Dr. Lee.

“CDI-988 may revolutionize the management of the highly contagious norovirus, which is known for quickly spreading in hospitals, nursing homes, cruise ships, schools, disaster relief sites, military settings and other semi-closed environments,” said James Martin, CFO and co-CEO. “Used as a prophylaxis, oral CDI-988 could offer a potential solution and add a new layer of defense.”

CDI-988 was designed with Cocrystal’s proprietary structure-based drug discovery platform technology. In August 2025 Cocrystal announced favorable Phase 1 safety and tolerability data from all CDI-988 dose cohorts including the highest dose of 1200 mg. In September 2025 the Company received a Study May Proceed Letter from the FDA for the Phase 1b challenge study.

• Received FDA IND clearance to evaluate CDI-988 as both norovirus preventive and treatment
• Expects to initiate CDI-988 Phase 1b norovirus challenge study in Q1 2026
• Granted NIH SBIR award to advance influenza A/B replication inhibitor program

BOTHELL, Wash., Nov. 14, 2025 (GLOBE NEWSWIRE) — Cocrystal Pharma, Inc. (Nasdaq: COCP) (“Cocrystal” or the “Company”) reports financial results for the three and nine months ended September 30, 2025, and provides updates on its antiviral product pipeline, upcoming milestones and business activities.

“We expect to begin enrolling participants in the first quarter of 2026 for our norovirus challenge study evaluating CDI-988, our oral broad-spectrum protease inhibitor,” said Sam Lee, Ph.D., President and co-CEO of Cocrystal. “This study will provide an initial assessment of CDI-988 for both prevention and treatment of norovirus infection. Norovirus is a major cause of acute gastroenteritis and is highly contagious. It spreads rapidly in enclosed environments such as cruise ships, military bases, nursing homes, and hospitals. At present, there is no FDA-approved treatment or prevention for norovirus infection.

“We were honored to receive a Small Business Innovation (SBIR) award from the National Institutes of Health (NIH) to advance our work in developing a novel, broad-spectrum lead candidate targeting the influenza A/B polymerase complex,” added Dr. Lee. “This recognition further validates the strength of our structure-based drug discovery platform technology and its capability to develop innovative antiviral therapies for addressing unmet medical needs.”

“Together with the non-dilutive SBIR award, we strengthened our balance sheet through two recent at-the-market financings under Nasdaq rules,” said James Martin, Cocrystal’s CFO and co-CEO. “This enhanced cash position supports the continued development of our product pipeline, including our potentially groundbreaking norovirus program.”

In September 2025 Cocrystal raised gross proceeds of $4.7 million from a registered direct offering along with a private placement of warrants that, if fully exercised on a cash basis, will raise an additional $8.3 million. In October 2025, the Company completed a private placement with directors and management for gross proceeds of $1.03 million with warrants that, if fully exercised on a cash basis, will raise an additional $1.83 million.

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.

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.

With 685 million global cases annually and a $60 billion worldwide economic impact, norovirus represents one of healthcare’s most pressing unmet needs. 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 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 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).
  • In September 2025 we received a Study May Proceed Letter from the FDA to conduct a Phase 1b challenge study in the U.S. evaluating CDI-988 as a norovirus preventive and treatment.
  • Preparations are underway for the challenge study, with subject enrollment expected to begin in the first quarter of 2026.
    

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 approximately 1 billion cases of seasonal influenza, 3-5 million severe illnesses and up to 650,000 deaths are reported worldwide. 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.
  • In November 2025 our Phase 2a study was completed, with CC-42344 showing a favorable safety and tolerability profile with no serious adverse events (SAEs) and no drug-related discontinuations by study participants. Efficacy analyses were not reported due to issues in trial conduct.
  • We plan to continue development of oral CC-42344 as a treatment for pandemic and seasonal influenza A.

• 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 developed a dry powder inhalation formulation and have completed toxicology studies.

Further information on our risk factors is contained in our filings with the SEC, including our Annual Report on Form 10-K for the year ended December 31, 2024. Any forward-looking statement made by us herein speaks only as of the date on which it is made. Factors or events that could cause our actual results to differ may emerge from time to time, and it is not possible for us to predict all of them.
