FDA Clears Appili Therapeutics to Expand its Phase 2 Clinical Trial of Favipiravir for the Potential Prevention of COVID-19


Appili Therapeutics Inc. recently announced the  US FDA has granted the company clearance to proceed after Appili’s filing of an investigational new drug (IND) application for broad-spectrum antiviral favipiravir. Appili is expanding its Phase 2 clinical trial into the US to evaluate the safety and efficacy of favipiravir tablets in controlling outbreaks following exposure to COVID-19 in long-term care (LTC) facilities. Appili’s Phase 2 clinical trial is leveraging the versatility of favipiravir as an oral tablet suitable for administration across a wide variety of care settings, including long-term care. Appili intends to enroll up to 760 participants in this Phase 2 clinical trial across both the US and in Canada. Health Canada provided regulatory clearance on May 21, 2020, for Appili’s Phase 2 study evaluating FUJIFILM Toyama Chemical’s (FFTC) favipiravir as a preventative measure against COVID-19 outbreaks.

“The burden of illness in long-term care centers continues to be a significant problem, and finding ways to offer LTC residents and staff protection against COVID-19 with an oral treatment would be a significant advance in our fight to control the devastating effects of this pandemic,” said Dr. Armand Balboni, Chief Executive Officer at Appili Therapeutics. “The limited response to vaccines often seen in the elderly further supports expanding this trial into the US. Favipiravir is an antiviral that can be administered orally as a tablet, without the need to be given intravenously or as injections, and may be an important option to avoid and/or control outbreaks in elderly residents living in LTC facilities.”

“The elderly are at the highest risk for contracting the disease and the rising rates of COVID-19 infection currently seen in much of the US will likely continue to be a major threat to those living and working in long-term care facilities,” said Primary Investigator Dr. Allison McGeer, senior clinician scientist at the Lunenfeld-Tanenbaum Research Institute at Sinai Health. “Through the means of a randomized control clinical trial, our team is looking forward to working with clinical partners in the US to understand if favipiravir could be an option for outbreak control in this setting.”

Favipiravir was originally developed and approved in Japan as a treatment and stockpile countermeasure for pandemic influenza outbreak under the name AVIGAN. Following promising clinical studies, Russia and India recently approved favipiravir-based antiviral medications for the emergency treatment of COVID-19. Researchers are conducting additional trials evaluating favipiravir as a treatment for COVID-19 in countries including the US, Japan, China, and the UK.

Appili Therapeutics Inc. was founded to advance the global fight against infectious disease by matching clearly defined patient needs with drug development programs that provide solutions to existing challenges patients, doctors, and society face in this critical disease space. Appili has built a pipeline of assets designed to address a broad range of significant unmet medical needs in the infectious disease landscape. This diverse pipeline aims to address some of the most urgent threats in global public health, including ATI-2307, a novel, broad spectrum, clinical-stage antifungal candidate in development for severe and difficult-to-treat invasive fungal infections; ATI-1701, a vaccine candidate for tularemia, a very serious biological weapons threat; ATI-1503, a drug discovery program aimed at generating a novel class of antibiotics with broad-spectrum activity against Gram-negative superbugs; and ATI-1501, which employs Appili’s proprietary, taste-masked, oral-suspension technology with metronidazole for the growing number of patients with difficulty swallowing. In addition, the Company is also testing FUJIFILM Toyama Chemical Inc.’s drug favipiravir for the prevention of COVID-19 as a potential prophylaxis treatment. Headquartered in Halifax, Nova Scotia, with offices in Toronto, Ontario, Appili is pursuing worldwide opportunities in collaboration with scientific and industry commercial partners, governments and government agencies.
