AIM ImmunoTech Announces Central IRB Approval of Phase 2 Study Protocol Evaluating Ampligen® for the Treatment of Post-COVID Conditions

Preliminary data of Ampligen seen to date demonstrates potential to be an effective treatment option for post-COVID conditions

OCALA, Fla., April 04, 2023 — AIM ImmunoTech Inc. (NYSE American: AIM) (“AIM” or the “Company”), an immuno-pharma company focused on the research and development of therapeutics to treat multiple types of cancers, immune disorders and viral diseases, today announced central Institutional Review Board (“IRB”) approval for the protocol of its Phase 2 study evaluating Ampligen® as a therapeutic for patients with post-COVID conditions (“AMP-518”). With this approval in hand, AIM is moving forward with the start-up process for the study’s planned clinical sites.

The AMP-518 clinical trial is a two-arm, randomized, double-blind, placebo-controlled, multicenter study to evaluate efficacy and safety of Ampligen in patients experiencing the post-COVID condition of fatigue. The primary outcome measure of the study is change from baseline to week 13 in PROMIS® Fatigue Score. Other 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.

AIM Chief Executive Officer Thomas K. Equels commented, “This is an important step forward in the development of Ampligen as a potential therapeutic for the treatment of post-COVID chronic fatigue-like conditions. We continue to be encouraged by the pilot data demonstrated to date and believe Ampligen has the potential to meet an important growing unmet medical need, with a patient population that exceeds several million in the United States alone, with even more worldwide. With central IRB approval, our team is working toward getting our pre-selected sites open so that patient enrollment and dosing can be up and running as quickly and efficiently as possible.”

AMP-518 is expected to enroll approximately 80 subjects between the ages of 18 to 60 years across up to 10 centers in the United States. Patients will be randomized 1:1 to receive twice weekly IV infusions of Ampligen or placebo for 12 weeks with a follow up phase of two weeks. The Company expects to begin patient enrollment and dosing in the AMP-518 study in Q2 2023.
