• Novel, potent pan-viral inhibitors targeting the viral replication complex are under development for the treatment of hantavirus, bunyavirus and influenza
• Hantavirus and bunyavirus infections represent significant unmet medical needs, contribute to ongoing global outbreaks and have no approved treatments or vaccines

BOTHELL, Wash., May 26, 2026 (GLOBE NEWSWIRE) — Cocrystal Pharma, Inc. (Nasdaq: COCP) (“Cocrystal” or the “Company”) announces that its novel direct-acting antivirals demonstrate pan-viral activity against multiple viruses, including hantavirus, bunyavirus and influenza. These antiviral molecules target a highly conserved region of the viral replication enzyme, specifically the L-protein of Andes hantavirus, which is essential for viral replication and transcription. In vitro potency data show superior activity (IC₅₀ <50 nM) against hantaan virus, which is closely related to the Andes hantavirus strain associated with recent outbreaks.

“We are thoughtfully leveraging our expertise in viral replication enzymes and structure-based drug discovery to develop the next generation of pan-viral replication inhibitors. Our first pan-viral protease inhibitor, CDI-988, recently advanced to a Phase 1b norovirus challenge study in the United States. Our research efforts have expanded to novel pan-viral replication inhibitors with the goal of developing a novel pan-viral lead molecule for multiple viral diseases caused by hantaviruses, bunyaviruses and influenza viruses,” said Sam Lee, Ph.D., President and co-CEO of Cocrystal Pharma. “We are encouraged by our initial in vitro potency data against hantavirus and plan to evaluate in vitro antiviral activity against the Andes hantavirus replication enzyme. We look forward to exploring collaborations and partnerships to address these urgent unmet needs.”

The Andes hantavirus was recently responsible for a deadly outbreak on a cruise ship, infecting up to 11 passengers and crew, resulting in three deaths. Hantaviruses are primarily transmitted by rodents, although human-to-human transmission can occur through prolonged close contact. Andes hantavirus, a member of the genus Hantavirus, is endemic in Argentina and Chile and causes hantavirus cardiopulmonary syndrome (HCPS), which is associated with a case fatality rate of up to 50%. Currently, there are no approved antivirals or vaccines for Andes hantavirus or other hantaviruses.

• Ongoing Phase 1b human challenge study with oral, direct-acting protease inhibitor is designed to demonstrate proof-of-concept as a preventive and a treatment
• Fully enrolled first cohort is assessing the infectivity of the human challenge inoculum
• There are no approved treatments or vaccines for norovirus, the leading cause of acute gastroenteritis across all age groups and geographies with a $60 billion annual economic burden
• FDA Fast Track designation granted for CDI-988 underscores the lack of approved therapies and seriousness of norovirus infection

BOTHELL, Wash., April 30, 2026 (GLOBE NEWSWIRE) — Cocrystal Pharma, Inc. (Nasdaq: COCP) (“Cocrystal” or the “Company”) announces that the mechanism of action and clinical advancement of its first oral protease inhibitor CDI-988 were featured today in an oral presentation at the 39^th International Conference on Antiviral Research (ICAR 2026) in Prague, Czech Republic. The presentation, titled “First Oral Direct-Acting Antiviral CDI-988 for Norovirus Infection Prevention and Treatment: Novel Mechanism of Action and Phase 1 Study Results,” was delivered by Sam Lee, Ph.D., President and co-CEO of Cocrystal. Presentation slides are available on the Company’s website here.

“It was an honor to share our progress with CDI-988 with the global antiviral research community attending ICAR 2026,” said Dr. Lee. “Following favorable Phase 1 data, we have advanced CDI-988 into a Phase 1b study under a human challenge model that provides an efficient framework to rapidly demonstrate proof of concept as a preventive and as a treatment for norovirus infection. We have now completed enrollment of the stage 1 study cohort, which will establish the infectivity rate of the GII.2 (Snow Mountain Virus) challenge inoculum. This is a critical step in validating infectivity in the study cohorts.

“Multiple norovirus vaccine clinical studies have been initiated over the past decade, yet none have led to an approval in part due to the virus’s extensive genetic variation and drift, spanning 10 genogroups and 49 genotypes,” Dr. Lee added. “CDI-988 is designed to target the highly conserved region of the 3CL protease across all known norovirus strains, including GII.4 and the re-emerging GII.17 variants, as well as all coronaviruses. We believe this compound could offer a much‑needed option for prevention and treatment in a convenient oral formulation that can be readily stockpiled in advance of norovirus outbreaks.”

CDI-988 is a first, oral direct-acting antiviral and was developed using Cocrystal’s proprietary structure-based drug discovery platform technology. As presented by Dr. Lee, in preclinical studies CDI-988 showed favorable gastrointestinal-targeted pharmacokinetics at the site of norovirus infection and also demonstrated potent antiviral activity in GII.4-infected human enteronoid model systems.

In a completed randomized, double‑blind, placebo‑controlled single‑ and multiple‑ascending dose Phase 1 study in healthy adults, CDI‑988 was generally safe and well tolerated across doses up to 1,200 mg, with headache as the most common treatment‑emergent adverse event and no serious adverse events reported. These results, together with a no-observed adverse effect of 1,000 mg/kg in GLP toxicology studies, support CDI-988’s further clinical development in norovirus.

The ongoing Phase 1b randomized, double‑blind, placebo‑controlled challenge study (NCT07198139) is being conducted at Emory University School of Medicine in collaboration with the University of North Carolina. The study is designed to enroll up to 40 healthy adults, ages 18 to 49, in staged cohorts. The stage 1 infectivity cohort, now fully enrolled, will be followed by prevention and treatment cohorts in which CDI‑988 is administered at 1,200 mg twice daily for five days. The primary efficacy endpoint is reduction in the incidence of clinical symptoms, with secondary endpoints including reduction in viral shedding, disease severity, safety and pharmacokinetics.

CDI‑988 has been granted Fast Track designation by the U.S. Food and Drug Administration (FDA) for the treatment and prophylaxis of norovirus infection, underscoring the serious nature of norovirus disease and the lack of approved therapies. Fast Track status is intended to facilitate development and expedite the review of drugs that address unmet medical needs, providing opportunities for more frequent FDA interactions, rolling review of a potential New Drug Application and potential eligibility for Priority Review.

• 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.

• CDI-988 is a direct-acting, oral antiviral being developed for norovirus
• Norovirus challenge study is underway at Emory University School of Medicine to evaluate efficacy and safety of CDI-988
• No approved treatments or vaccines are available for norovirus treatment and prevention, posing a significant unmet need and contributing to a global economic burden of $60 billion annually
  

BOTHELL, Wash., March 09, 2026 (GLOBE NEWSWIRE) — Cocrystal Pharma, Inc. (Nasdaq: COCP) (“Cocrystal” or the “Company”) announces the first subjects have been dosed in a Phase 1b norovirus challenge study (NCT07198139) to evaluate CDI-988 as both a preventive and treatment for norovirus infections. This cohort is to assess the infectivity rate of the challenge inoculum, GII.2 (Snow Mountain Virus). CDI-988 is a direct-acting, oral antiviral designed to inhibit a highly conserved region of the viral 3CL protease present in all known norovirus strains, including GII.2, GII.4 and recently re-emerging GII.17 variants. It is the first oral antiviral drug candidate developed for norovirus acute gastroenteritis.

“Commencement of this study is a significant milestone for Cocrystal and a critical step toward addressing a serious global unmet medical need, given the debilitating symptoms and high societal cost of norovirus outbreaks,” said Sam Lee, Ph.D., President and co‑CEO of Cocrystal Pharma. “CDI-988 has particular potential in high‑risk environments such as hospitals, nursing homes, cruise ships, schools and military facilities. The human challenge model is designed to provide proof‑of‑concept for our compound in a tightly controlled setting.”

The Phase 1b randomized, double-blind, placebo-controlled study is being conducted at Emory University School of Medicine and will enroll up to 40 healthy subjects ages 18–49. All participants will be infected with the norovirus GII.2 (Snow Mountain Virus) strain.

• The first cohort will evaluate the infectivity rate of the challenge inoculum, GII.2 norovirus
• Subsequent cohorts will be orally administered CDI-988 or placebo
• The primary endpoint is efficacy versus placebo in reducing the incidence of clinical symptoms
• Secondary endpoints include reduction of viral shedding and disease severity, and safety and pharmacokinetic profiles

“This challenge study is the first clinical trial involving a direct-acting antiviral specifically targeting norovirus infections. The efficacy and safety data from this study are expected to provide a strong rationale for further clinical advancement of CDI-988, and validate our proprietary structure-based drug discovery platform technology,” added Dr. Lee. “We would like to thank the volunteers for the norovirus challenge study and staff from Emory University School of Medicine who are currently participating in the study.”

CDI-988 previously demonstrated favorable safety and tolerability in a Phase 1 study across all dose levels, including the highest dose of 1200 mg being administered in the Phase 1b human challenge study. In September 2025 Cocrystal received a Study May Proceed Letter from the FDA and in December 2025 received Institutional Review Board approval from Emory University School of Medicine.

• 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.
