Axcella Therapeutics Announces FDA IND Clearance Supporting Regulatory Path to Registration of AXA1125

Axcella Therapeutics (Nasdaq: AXLA), a clinical-stage biotechnology company pioneering novel approaches to treating complex diseases using multi-targeted endogenous metabolic modulator (EMM) compositions, today announced its Investigational New Drug (IND) application to initiate a phase 2b/3 trial in the U.S. for AXA1125 in the treatment of Long COVID Fatigue has been cleared by the U.S. Food and Drug Administration (FDA). The company reported that it had received regulatory guidance from the FDA, supporting a trial that is designed to serve as the registration trial for patients with Long COVID Fatigue. The study design now has acceptance from both the U.S. and U.K. regulatory authorities. Last month, the company announced a regulatory path to registration of AXA1125 in the treatment of Long COVID Fatigue, and that it had received regulatory guidance from The Medicines and Healthcare products Regulatory Agency (MHRA), the U.K.’s regulatory agency, supporting a single trial that could serve as the registration trial for patients with Long COVID Fatigue.

The guidance from the FDA and the MHRA follows the company’s submission of materials to both regulatory agencies including results from the Phase 2a randomized, double-blind, placebo-controlled investigation to evaluate the efficacy and safety of AXA1125 in patients with fatigue related to Long COVID. The study found that subjects who received AXA1125 experienced clinically and statistically significant improvement in mental (p=0.0097) and physical (p=0.0097) fatigue scores compared to placebo subjects. Consistent with the Ph2a trial, the Ph2b/3 trial will enroll participants who have had fatigue for at least 12 weeks after COVID-19 infection. The primary endpoint will utilize the same patient reported outcome tool, the Chalder Fatigue Questionnaire (CFQ-11), to measure improvements in fatigue. Additional endpoints will evaluate improvements in physical function, quality of life, and ability to return to work. Participants will receive either placebo or AXA1125 for three months.

“We’re excited to now have the regulatory clearance from both the U.S. and U.K. authorities to advance our Long COVID program into a trial that can lead to registration,” said Bill Hinshaw, CEO of Axcella. “The guidance from the FDA demonstrates continued progress, following the MHRA milestone a few weeks ago, providing clear next steps in this important, ongoing, and as-yet untreated disease. There are millions of people around the world suffering from Long COVID Fatigue who are without options. Axcella has the leading program in the field, and this regulatory feedback provides the next step in developing a potential Long COVID Fatigue treatment.”

“We are pleased to obtain FDA clearance for this phase 2b/3 study, following our positive feedback from the MHRA,” said Margaret Koziel, M.D., Chief Medical Officer of Axcella. “Both on an individual and a societal level, the impact of Long COVID on the ability to have a full and productive life is significant, and we hope to offer a solution to these patients.”

Dr. Koziel will be presenting at a forum on February 21 that will bring hundreds of stakeholders together to discuss how the government and private industry can foster greater and more urgent public-private engagement on treatments for Long COVID. The forum is co-sponsored by the Biotechnology Innovation Organization (BIO) and SOLVE M.E., a non-profit organization that serves as a catalyst for critical research into diagnostics, treatments, and cures for myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), Long COVID and other post-infectious diseases. Axcella will make a presentation at the forum to discuss its novel approach to treating Long COVID Fatigue and its promising clinical data.

“Treatment with AXA1125 resulted in statistically significant improvement in mental and physical fatigue scores, compared to placebo, in a well-designed and carefully conducted randomized controlled trial,” added Jason Maley, M.D., Director of the Beth Israel Deaconess Medical Center COVID-19 Survivorship Program. “I’m eager to see AXA1125 move into a phase 2b/3 study. This work is important to help patients with Long COVID who commonly experience debilitating daily fatigue.”

“There remains an urgent need for treatment developed specifically for the millions of patients suffering from Long COVID Fatigue, a disease that is having a devastating health and economic impact,” said Oved Amitay, Chief Executive Officer of Solve M.E. Amitay, who also is the co-founder of the Long COVID Alliance, a network of patient-advocates, scientists, disease experts, and drug developers focused on educating policy makers and accelerating research into post-viral illnesses, added, “I am looking forward to the conversation at the BIO and SOLVE forum, where I expect multiple stake-holders to continue to advance progress for Long COVID patients.”

Long COVID is a persistent and growing long-term consequence of the pandemic, affecting an estimated one hundred million patients worldwide, with fatigue as the most commonly reported symptom. Recent estimates indicate that 15-20% of Americans with COVID have persisting health issues,i up to four million Americans are out of work due to Long COVID symptoms, and that Long COVID has contributed to approximately $1 trillion in lost earnings and $544 billion in increased medical spending.ii
