Infectious disease-focused biopharmaceutical company, Appili Therapeutics Inc., today announced that the Phase 3 PRESECO clinical trial evaluating oral antiviral Avigan®/Reeqonus™(favipiravir) for the treatment of mild-to-moderate COVID-19 did not achieve statistical significance on the primary endpoint of time to sustained clinical recovery. Additional analyses of the trial data are ongoing. The clinical trial enrolled 1,231 patients with mild-to-moderate COVID-19 from 38 study sites across the United States, Mexico, and Brazil.
“While we are disappointed by the topline results of the PRESECO trial, we remain steadfast in our belief that safe and effective oral antivirals are urgently needed for patients who are still struggling to overcome COVID-19. We wish to thank all the patients who participated, and hope that information obtained from our trial can help guide research and development around more potential treatment options for COVID-19,” said Dr. Armand Balboni, Chief Executive Officer, Appili Therapeutics. “Appili remains committed to addressing the challenges posed by infectious diseases and we will continue developing our pipeline to improve patient lives around the world.”
The Phase 3 PRESECO (PREventing SEvere COVID-19 Disease) study is a double-blind, placebo-controlled, randomized, multi-center, global superiority trial investigating the safety and efficacy of oral Avigan/Reeqonus in the early treatment for adults infected with COVID-19 and showing mild-to-moderate symptoms. Participants were enrolled at multiple clinical trial sites in the United States, Brazil and Mexico. Participants were outpatients with mild-to-moderate symptoms who have had a recent positive COVID-19 test (within 72 hours of enrollment). Participants self-administered the drug regimen in their homes, with clinical investigators monitoring patients remotely.
Avigan/Reeqonus is a broad-spectrum antiviral in oral tablet form. It is a selective inhibitor of viral RNA-dependent RNA polymerase (RdRP) with potent antiviral activity against single-stranded RNA viruses, including coronaviruses. Developed by FUJIFILM Toyama Chemical Co., Ltd. (FFTC) and approved in Japan as a treatment and stockpile countermeasure for pandemic influenza. Unlike most other interventions that researchers are evaluating in COVID-19, Avigan/Reeqonus has already been thoroughly studied in human trials and has a well-known safety profile, with over 3,000 subjects receiving at least one dose of the drug. Avigan/Reeqonus’ oral tablet form is shelf-stable and has an established commercial manufacturing process, which may provide advantages over other COVID-19 interventions, which often require temperature-controlled storage and/or injection or intravenous administration.
