Tetra Bio-Pharma Announces Results of Artificial Intelligence Study of ARDS-003 Combined with Favipiravir


  • The combination of ARDS-003 and Favipiravir presents viable treatments against viral infections.

  • Results from the PIONEER clinical trial shows Favipiravir may improve severe COVID-19 recovery and ventilator-free survival in younger patients.

  • Tetra and Cellvera to develop an orally administered treatment, ARDS-003, in combination with Favipiravir.

MONTREAL, Dec. 6, 2022 /CNW/ – Tetra Bio-Pharma Inc. (“Tetra” or the “Company”) (TSX: TBP) (OTCQB: TBPMF) (FRA: JAM1), a leader in cannabinoid-derived drug discovery and development announced today significant results from the study of Onternabez combined with Favipiravir against ARDS (acute respiratory distress syndrome), Sepsis, and COVID-19 through PREPAiRE, an AI (Artificial Intelligence) powered platform which purposely integrates target identification, validation, lead discovery optimization, drug synthesis, and preclinical testing. Leveraging the power of AI enables more answers and greater insights, faster.

Results from the study demonstrate that Tetra’s investigational therapeutic, ARDS-003, which contains the active pharmaceutical ingredient Onternabez, acts against various ARDS and Sepsis targets, such as IL-6 and IL-8. Onternabez plays an important role in mitigating the inflammatory response in various targets of inflammatory conditions. Favipiravir acts against different SARS-CoV-2 targets, such as spike glycoprotein and nucleoprotein.  The interaction between Favipiravir and Onternabez against SARS-COV-2 yields a positive Molecule Synergy probability which is considered significant and justifies the combination of the two drugs to create a new therapeutic that is expected to be beneficial to increase treatment efficacy and reduce the duration of disease. Favipiravir can control the source of infection. Onternabez would contribute to the antiviral efficacy and can control the result of infection (i.e., the inflammatory response).

Dr. Guy Chamberland, CEO and Chief Regulatory Officer at Tetra commented “We are very pleased by these artificial intelligence results as well as the recent positive results from the PIONEER trial. This underscores our commitment with Cellvera to developing an innovative combination drug candidate to combat viral diseases. We are more excited than ever about our collaboration with Cellvera and the possibility of delivering the next scientific breakthroughs.”

About the PIONEER clinical trial – Cellvera’s Press Release

On October 11, 2022, Cellvera, shared an update that the UK’s Chelsea and Westminster NHS Foundation Trust sponsored PIONEER trial involving Avigan® (Favipiravir) vs. standard care confirms a reduction in deaths by 22% compared to the placebo group. Cellvera, directly or through their affiliates, holds exclusive worldwide rights to brand originator Favipiravir under the brand names Avigan® 200MG and Qifenda® 400mg/800MG and the injectable formulation. This broad-spectrum therapeutic has shown antiviral effects against SARS-CoV-2 (the virus responsible for causing COVID-19) and more than 20 other RNA viruses.

Favipiravir may improve severe COVID-19 recovery, ventilator-free survival in younger patients was the headline-grabbing statement after a presentation made by Dr/ Christopher M. Orton, MD, Consultant Respiratory Physician at Royal Brompton Hospital, London, during a presentation at the European Respiratory Society International Congress.

PIONEER: A Randomised Controlled Trial of Early Intervention in Patients Hospitalized with COVID-19: Favipiravir verses Hydroxychloroquine & azithromycin & zinc vErsEs Standard CaRe. The international PIONEER study, sponsored by Chelsea and Westminister Hospital NHS Foundation Trust, recruited 499 patients (median age, 58.9 years; 61% men) from the U.K., Brazil, and Mexico who were admitted to hospitals with proven or suspected COVID-19 from May 2020 to May 2021. Led by an expert clinical team and supported by NEAT ID, the study was financially supported by a group of leading organizations and individuals who committed funds to the trial, including Imperial College, Chelsea and Westminster Hospital NHS Foundation Trust, XTX Markets, medical research charity LifeArc, KU Leuven, and Ageas, and a broad community of individual donors.

Researchers reported that treatment with oral Favipiravir benefited recovery and mechanical ventilation-free survival among patients younger than 60 years hospitalized with COVID-19. The primary outcome was time to a 2-point improvement in the WHO ordinal scale or discharge, whichever occurred first. Secondary outcomes focused on mortality and health care resource utilization. When findings were analyzed for patients aged younger than 60 years, researchers observed a more significant numerical difference in deaths, with an approximate 50% reduction and a significant difference in mechanical ventilation-free survival (p=.02)

The PIONEER trial compared two potential antiviral treatments for early intervention in patients with COVID-19. The treatments initially selected were Avigan® (Favipiravir) and an Hydroxychloroquine/ azithromycin & zinc combination. The treatments were chosen due to their potential to be used for early intervention by inhibiting the virus’s ability to replicate and prevent the progression of the disease to the later, more severe phase. However, acting on guidance from the MHRA, the combination treatment arm of Hydroxychloroquine/azithromycin & zinc was dropped while safety issues around HCQ were being investigated. The PIONEER study continued with only one arm, that of Avigan® (Favipiravir) vs. standard care.

Research organizations involved:

FUJIFILM Toyama Chemicals provided Avigan® with relevant safety information to obtain the official approvals necessary to start the trial. Favipiravir, which has a long and verified history of safety and efficacy, was initially developed by FujiFilm Toyama Chemical Co and approved in Japan (2014) to treat pandemic influenza. Favipiravir is a selective inhibitor of viral RNA-dependent RNA polymerase (RdRP) with potent antiviral activity against single-stranded RNA viruses, including coronaviruses. It targets the protein needed for the coronavirus to replicate, making it impossible for the virus to copy itself. The broad-spectrum antiviral drug is effective against 12 families of viruses, including Coronaviruses (COVID, MERS, SARS), Filoviruses (EBOLA, MARBURG), Flaviviruses (ZIKA, WEST NILE, DENGUE), RABIES, NOROVIRUS, and many others.

Mary O’ Brien Chief Executive Officer commented on data made available by Dr. Orton to colleagues at the European Respiratory Society International Congress from the PIONEER trial; “The recent presentation re-confirms the potential Favirpiravir has to save people’s lives and reduce the severity of the COVID-19 infection. We already know the profound impact Avigan® 200MG and Qifenda® 400MG has made in controlling the pandemic. It was one of the first oral antivirals to be approved as a treatment for COVID-19 and is already used by governments as the first line of defense in treating the virus. With these compelling results, and more to come, we are optimistic that Avigan® and higher strength formulations of Favirpiravir will grow as an essential drug in the global effort to fight this and future pandemics, reinforcing Cellvera’s ambition to bring forward breakthroughs in infectious diseases when they are needed most.”

About FAVIPIRAVIR

Favipiravir, discovered and developed by FUJIFILM, was first approved under the brand name Avigan® by regulators in Japan in 2014 as a potent broad-spectrum antiviral treatment for influenza. This antiviral drug is effective against 12 families of viruses, including coronaviruses (COVID, MERS, SARS), Filoviruses (EBOLA, MARBURG), Flaviviruses (ZIKA, WEST NILE, DENGUE), RABIES, NOROVIRUS, and many others. Favipiravir works by inhibiting a viral enzyme called RNA polymerase, preventing viral replication within human cells. Favipiravir has potent antiviral activity against single-stranded RNA viruses, including coronaviruses. This is the protein responsible for “building” the viral proteins. Favipiravir can target the protein necessary for the coronavirus to replicate, making it impossible for the virus to copy itself.
