Topline data expected as early as Q1 2024

OCALA, Fla., Aug. 08, 2023 — AIM ImmunoTech Inc. (NYSE American: AIM) (“AIM”) today announced the completion of enrollment in the company’s Phase 2 study evaluating Ampligen® as a potential therapeutic for people with post-COVID conditions (“AMP-518”).

The study has met the planned enrollment of 80 AMP-518 subjects ages 18 to 60 years who have been randomized 1:1 to receive twice-weekly intravenous infusions of Ampligen or placebo for 12 weeks, with a follow-up phase of two weeks. The company expects to complete dosing of the last study patient in Q4 2023. Topline data is expected as early as Q1 2024.

AIM Chief Executive Officer Thomas K. Equels commented, “We are incredibly pleased with the extremely rapid pace of enrollment for AMP-518. The completion of enrollment in such a short timeframe highlights the unmet medical need for a therapeutic option to treat Long COVID with chronic fatigue-like symptoms. We continue to be encouraged by the potential of Ampligen and are working diligently to bring this study across the finish line with the ultimate goal of helping the millions of people struggling with this debilitating and life-altering syndrome.”

Oved Amitay, President and CEO of the national advocacy organization Solve M.E., commented, “The CDC estimates that approximately four million Americans are struggling with significant activity limitations from Long COVID, presenting extreme challenges for patients, their caregivers and their families. Complete AMP-518 study enrollment is a critical step in the ongoing effort to develop Ampligen as a therapeutic to address the debilitating aspects of Long COVID and to bring hope not only to the millions of people affected by this disease, but also to the many people suffering from associated conditions such as myalgic encephalomyelitis, also known as chronic fatigue syndrome or ME/CFS.”

The AMP-518 clinical trial is a two-arm, randomized, double-blind, placebo-controlled, multicenter study to evaluate efficacy and safety of Ampligen in subjects experiencing the post-COVID condition of fatigue. The primary protocol planned outcome measure of the study is change from baseline to week 13 in PROMIS® Fatigue Score. Other protocol planned study outcomes include: change from baseline to week 6 in PROMIS® Fatigue Score; change from baseline to weeks 6 and 13 in distance traveled during a Six-Minute Walk Test; proportion of subjects that surpass 54 meters in the Six-Minute Walk Test at the end of 12-week treatment phase; change from baseline to weeks 6 and 13 in PROMIS® Cognitive Function Score; and change from baseline to weeks 6 and 13 in PROMIS® Sleep Disturbance Score.
