• Completed enrollment in the Phase 1 study with novel, broad-spectrum antiviral PB2 candidate CC-42344 for the treatment of pandemic and seasonal influenza A; remains on track to report topline results in 2022
• Announced oral presentation of CC-42344 Phase 1 influenza A data at the World Antiviral Congress 2022 being held in December
• Selected novel antiviral candidate CDI-988 for clinical development as an oral treatment for SARS-CoV-2 with Phase 1 study expected to begin in the first quarter of 2023
  

BOTHELL, Wash., Nov. 14, 2022 (GLOBE NEWSWIRE) -- Cocrystal Pharma, Inc. (Nasdaq: COCP) reports financial results for the three and nine months ended September 30, 2022, and provides updates on its antiviral pipeline, upcoming milestones and business activities.

“We are reporting continued progress in advancing our highly promising antiviral portfolio,” said Sam Lee, Ph.D., President and co-interim CEO of Cocrystal. “With enrollment completed in our CC-42344 Phase 1 study for the treatment of pandemic and seasonal influenza A, we are on track to report topline safety and pharmacokinetic (PK) results later this year. The full trial results will be a key component of UK regulatory agency submission for our influenza A Phase 2a human challenge study. Subject to the agency’s review and clearance of our submission, we expect Phase 2a study initiation in the second half of 2023.

“We advanced our oral COVID-19 program with the selected the novel, broad-spectrum protease inhibitor CDI-988 as our lead development candidate,” he added. “We are conducting IND-enabling toxicology studies with CDI-988 and plan to file for regulatory clearance to begin a first-in-human trial in Australia in the first quarter of 2023. Preclinical development activities are ongoing in our norovirus program with plans to select a lead candidate in the first half of 2023.”

“The recent increase in patients hospitalized with viral disease particularly among the pediatric population underscores the need for effective, broad-spectrum antivirals and provides rationale for our approach in developing candidates with barriers to drug resistance,” said James Martin, CFO and co-interim CEO. “We continue to be well positioned to execute on our clinical and regulatory goals given our clean capital structure, cost-efficient business model and a cash balance we believe is sufficient to fund planned operations for the next three years. That said, we continue to pursue non-dilutive funding to further support development of our promising antiviral programs.”

Antiviral Product Pipeline Overview

Many commercial antiviral drugs are only effective against certain strains of a virus and are less effective or not effective at all against other strains or variants. Cocrystal is developing novel drug candidates that specifically target proteins involved in viral replication. Despite the numerous strains that may exist or emerge, these targeted enzymes are required for viral replication and are essentially similar (highly conserved) across all strains. By targeting these highly conserved regions of the replication enzymes, our antiviral compounds are designed to be effective against major virus strains.

COVID-19 and Other Coronavirus Programs
By targeting viral replication enzymes and protease, we believe it is possible to develop an effective treatment for all coronavirus diseases including COVID-19, Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS). Our main SARS-CoV-2 protease inhibitors showed potent in vitro pan-viral activity against common human coronaviruses, rhinoviruses and respiratory enteroviruses that cause the common cold, as well as against noroviruses that can cause symptoms of acute gastroenteritis.

During 2022 Cocrystal entered into two agreements with the National Institute of Allergy and Infectious Diseases (NIAID) for exploratory preclinical studies to evaluate our 3CL protease inhibitors for the treatment of COVID-19. The NIAID collaboration announced in April 2022 for in vitro and in vivo studies evaluating the antiviral activity of our compounds has been successfully completed. In June 2022 we expanded our collaboration with the NIAID with a second agreement in which we provided our proprietary process chemistry information for oral 3CL protease inhibitors to the NIAID to support scale-up synthesis of a key intermediate of these compounds. This collaboration is ongoing.

• Oral Protease Inhibitor CDI-988
  • We selected CDI-988 as our lead candidate for development as a potential oral treatment for SARS-CoV-2. CDI-988, which was designed and developed using our proprietary structure-based drug discovery platform technology, targets a highly conserved region in the active site of SARS-CoV-2 3CL (main) protease required for viral RNA replication.
  • CDI-988 exhibits superior in vitro potency against SARS-CoV-2 with activity maintained against current variants of concern, and demonstrated a safety profile and PK properties that are supportive of daily dosing.
  • We are currently conducting good laboratory practice (GLP) toxicology studies in preparation for a Phase 1 study.
  • We plan to initiate a Phase 1 study in the first quarter of 2023. We believe the FDA’s guidance for further development of our antiviral candidate CDI-45205 (described below) provides us with a clearer pathway for our planned Phase 1 study with CDI-988, as well as directives for designing a subsequent Phase 2 study.
    
    
• Intranasal/Pulmonary Protease Inhibitor CDI-45205
  
  
  • An IND-enabling study is ongoing with CDI-45205, our novel SARS-CoV-2 3CL (main) protease inhibitor being developed as a potential treatment for COVID-19 and its variants.
  • We received guidance from the FDA regarding further preclinical and clinical development of CDI-45205 that provides a clearer pathway for future clinical development.
  • CDI-45205 and several analogs showed potent in vitro activity against the main SARS-CoV-2 variants to date including the Omicron variant, surpassing the activity observed with the original Wuhan strain.
  • CDI-45205 demonstrated good bioavailability in mouse and rat PK studies via intraperitoneal injection, and no cytotoxicity against a variety of human cell lines. CDI-45205 also demonstrated a strong synergistic effect with the FDA-approved COVID-19 medicine remdesivir.
  • CDI-45205 was among the broad-spectrum viral protease inhibitors we obtained from Kansas State University Research Foundation (KSURF) under an exclusive license agreement announced in April 2020. We believe the protease inhibitors obtained from KSURF have the ability to inhibit the inactive SARS-CoV-2 polymerase replication enzymes into an active form.

• Replication Inhibitors
  • We are using our proprietary structure-based drug discovery platform technology to discover replication inhibitors for orally administered therapeutic and prophylactic treatments for SARS-CoV-2. Replication inhibitors hold potential to work with protease inhibitors in a combination therapy regimen.

Influenza Programs
Influenza is a severe respiratory illness caused by either the influenza A or B virus that results in outbreaks of disease mainly during the winter months.

• Pandemic and Seasonal Influenza A
  • A novel PB2 inhibitor, CC-42344 has shown excellent antiviral activity against influenza A strains including pandemic and seasonal strains, as well as strains resistant to Tamiflu^® and Xofluza^®. CC-42344 also has favorable PK and drug-resistance profiles.
  • In March 2022 we initiated enrollment in our randomized, double-controlled, dose-escalating Phase 1 study to evaluate the safety, tolerability and pharmacokinetics of orally administered CC-42344 in healthy adults.
  • In April 2022 we announced preliminary Phase 1 study data, demonstrating a favorable safety and PK profile in the first two cohorts administered single ascending doses of CC-42344 at 100 mg and 200 mg.
  • In July 2022 we reported PK results from the single ascending dose of the study supporting once-daily dosing.
  • In November 2022 we announced the Phase 1 study had reached full enrollment and reiterated our expectation to report topline results in 2022.
  • We entered into an agreement with a UK-based clinical research organization to conduct a human challenge Phase 2a study evaluating safety, viral and clinical measures of orally administered CC-42344 in influenza A-infected subjects. Under the human challenge model, healthy adults will be infected with the influenza A virus under carefully controlled conditions, which we believe will hasten trial enrollment and ensure subjects are infected with influenza A.
  • We expect to submit an application with the United Kingdom Medicines and Healthcare Products Regulatory Agency in early 2023 to conduct a human challenge Phase 2a study. Pending clearance by the agency, we expect to initiate the study in the second half of 2023.

• Pandemic and Seasonal Influenza A/B Program
  • In January 2019 we entered into an Exclusive License and Research Collaboration Agreement with Merck Sharp & Dohme Corp. (Merck) to discover and develop certain proprietary influenza antiviral agents that are effective against both influenza A and B strains. This agreement includes milestone payments of up to $156 million plus royalties on sales of products discovered under the agreement.
  • In January 2021 we announced completion of all research obligations under the agreement. Merck is now solely responsible for further preclinical and clinical development of compounds discovered under this agreement, and continues development activities with the compounds discovered under this agreement.
  • In April 2022 Merck indicated it was continuing development of the compounds discovered under this agreement.

Norovirus Program

• We are developing certain proprietary broad-spectrum, non-nucleoside polymerases for the treatment of human norovirus infections using our proprietary structure-based drug design technology platform. We also hold exclusive rights to norovirus protease inhibitors for use in humans under the KSURF license.
• We are targeting the selection of a preclinical lead in the first half of 2023.
• Norovirus is a global public health problem responsible for nearly 90% of epidemic, non-bacterial outbreaks of gastroenteritis around the world.
  

Hepatitis C Program

• We are seeking a partner to advance the development of CC-31244 following the successful completion of a Phase 2a study. This compound has shown favorable safety and preliminary efficacy in a triple-regimen Phase 2a study in combination with Epclusa (sofosbuvir/velpatasvir) for the ultra-short duration treatment of individuals infected with the hepatitis C virus (HCV).
• HCV is a viral infection of the liver that causes both acute and chronic infection. In June 2022, the World Health Organization estimates that 58 million people worldwide have chronic HCV infections.
