## Exhibit 99.1

**Exhibit 99.1**

**Cocrystal Pharma Reports 2025 Financial Results and Provides Updates on its Antiviral Drug-Development Programs**

● *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)** – 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.

*<u>Norovirus Program</u>*

 

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.

<u>With 685 million global cases annually and a $60 billion worldwide economic impact</u>, norovirus represents one of healthcare's most pressing unmet needs. <u>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</u>. The annual burden of norovirus to the U.S. is estimated at <u>$10.6 billion</u>. In the developing world, each year noroviruses are responsible for <u>up to 1.1 million hospitalizations and 218,000 pediatric deaths</u>.

 

*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<sup>th</sup> 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.

 

*<u>Influenza Programs</u>*

 

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. <u>About 8% of the U.S. population gets sick from flu each season</u>. In addition to the health risk, <u>influenza is responsible for an estimated $10.4 billion in direct medical costs in the U.S. each year</u>.

 

*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.

*<u>SARS-CoV-2 and Other Coronavirus Program</u>*

 

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**

Research and development expenses for 2025 were $5.1 million compared with $12.5 million for 2024, with the decrease primarily due to lower costs with the winddown of the Phase 2a influenza study and reduction in employee-related expenses. General and administrative expenses for 2025 were $4.0 million compared with $5.3 million for 2024, with the decrease primarily due to a reduction in compensation, insurance and corporate expenses.

Net loss for 2025 was $8.8 million, or $0.78 per share, compared with a net loss for 2024 of $17.5 million, or $1.72 per share.

Cocrystal reported unrestricted cash as of December 31, 2025, of $7.7 million compared with $9.9 million as of December 31, 2024.
