Independent Data Safety Monitoring Board Recommends Appili Therapeutics Complete Its Phase 3 Avigan®/Reeqonus™ Trial for Mild-to-Moderate COVID-19 Patients

HALIFAX, NS, May 17, 2021 /PRNewswire/ -- Appili Therapeutics Inc. (TSX: APLI, OTCQX: APLIF) (the “Company” or “Appili”), a biopharmaceutical company focused on drug development for infectious diseases, today announced that an independent Data and Safety Monitoring Board (DSMB) has recommended continuation without modification of Appili’s ongoing Phase 3 PRESECO (PREventing SEvere COVID-19) trial evaluating Avigan®/Reeqonus™ (favipiravir) as a potential oral therapy for patients with mild-to-moderate COVID-19.

“Even with effective vaccines available, COVID-19 is here to stay for the foreseeable future. A safe and effective oral anti-viral medicine is what government leaders and physicians around the world have been asking for since the start of the pandemic. We remain hopeful that once PRESECO is completed, Avigan/Reeqonus will emerge as the first prescription oral medicine for newly diagnosed patients with COVID-19,” said Dr. Armand Balboni, Chief Executive Officer, Appili Therapeutics.

The PRESECO study is evaluating the safety and efficacy of Avigan/Reeqonus, an oral antiviral that selectively inhibits viral RNA-dependent RNA polymerase (RdRP), as a potential treatment for patients with mild-to-moderate COVID-19. The primary goal of the study is to demonstrate a significant shortening of the time to sustained recovery for study patients receiving the experimental medicine compared to a placebo. The DSMB reported no safety issues that would have required the study to be terminated. It also did not recommend stopping the study for futility. As a result, Appili will continue the study without modification.

The interim analysis is based on data from approximately 600 subjects. Appili Therapeutics will continue recruiting patients at the 27 study sites across the United States and expects to report top-line results in Q3 2021, which will inform subsequent interactions with regulators, including the possibility Appili will pursue an Emergency Use Authorization from the U.S. Food and Drug Administration.

“COVID-19 is surging again in various parts of the world, including Asia and South America. As a practicing infectious diseases physician, I understand the importance of discovering and delivering new medicines to treat COVID-19 here and around the world,” said Yoav Golan, Chief Medical Officer, Appili.

About the PRESECO Clinical Trial
The Phase 3 PRESECO (Preventing Severe COVID-19 Disease) study is a double-blind, placebo-controlled, randomized, multi-center superiority trial investigating the safety and efficacy of Avigan/Reeqonus in the early treatment outpatient setting for adults infected with COVID-19 and showing mild-to-moderate symptoms. Investigators are enrolling participants at multiple clinical trial sites in the United States. Participants are expected to be outpatients who do not require hospitalization and who have had a recent positive COVID-19 test (within 72 hours of enrollment). Participants self-administer the drug regimen in their homes, with clinical investigators monitoring them remotely.

About Avigan/Reeqonus
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.

Appili has joined a consortium of companies, including Dr. Reddy’s Laboratories, Global Response Aid, and FFTC, for the worldwide development and distribution of Avigan/Reeqonus tablets for the potential treatment and prevention of COVID-19 (excluding Japan, China, and Russia.) This consortium is designed to ensure that Avigan/Reeqonus is thoroughly evaluated in rigorous clinical studies and, if it receives the proper regulatory approvals, has the infrastructure in place to support worldwide manufacturing and distribution.
