Company targets first quarter 2024 for trial initiation

Potential to be first orally-administered TNF-α inhibitor treatment for RA

MyMD Pharmaceuticals, Inc.® (Nasdaq: MYMD) (“MyMD” or “the Company”), a clinical stage biopharmaceutical company committed to developing novel therapies for age-related diseases, autoimmune and inflammatory conditions, announced today that its Investigational New Drug (IND) application for a Phase 2 clinical trial of oral MYMD-1® as a treatment for rheumatoid arthritis (RA) was recently cleared by the U.S. Food and Drug Administration (FDA), and plans are underway for trial launch in the first quarter of 2024.

“With the FDA’s recent clearance of our IND in RA, we are moving forward with plans to initiate a Phase 2 trial within the next several months. Results from preclinical studies have demonstrated MYMD-1’s potential to treat RA, and we believe this drug could one day be a disruptor in the massive market for similar treatments,” said Chris Chapman, M.D., president, director, and chief medical officer of MyMD.

Differentiated by its ease of oral dosing and selectivity, MYMD-1 is a TNF-α inhibitor with a small molecule design that enables the drug to cross the blood brain barrier for entry into the central nervous system. In a preclinical trial, MYMD-1 was shown to significantly reduce swelling and other clinical arthritis measures compared to widely used RA therapy Enbrel® (etanercept).¹ Disease severity (total composite score) was reduced by 47% with MYMD-1 (450 mg/kg/day orally) versus a 37% reduction with etanercept (10 mg/kg by subcutaneous injection).

Under this IND, the Phase 2 clinical trial of MYMD-1 will be a randomized placebo-controlled study that is expected to enroll approximately 60 patients with active rheumatoid arthritis. Patients will receive oral MYMD-1 dosing of 1050 mg.

Market Opportunity

Rheumatoid arthritis is a chronic, systemic inflammatory disorder that causes chronic inflammation of the joints and affects approximately 1.5 million Americans. RA’s cost to society, including healthcare costs; loss of employment; costs to employers, government, and caregivers; and costs associated with a deterioration of quality of life, is estimated to be over $40 billion annually.²

About MYMD-1

Originally developed for autoimmune diseases, MYMD-1’s primary purpose is to slow the aging process, prevent sarcopenia and frailty, and extend healthy lifespan. Because it can cross the blood-brain barrier and gain access to the central nervous system (CNS), MYMD-1 is also positioned to be a possible treatment for brain-related disorders. Its mechanism of action and efficacy in diseases including multiple sclerosis (MS) and thyroiditis have been studied through collaborations with several academic institutions.

MYMD-1 has shown effectiveness in preclinical and clinical studies in regulating the immune system by performing as a selective inhibitor of tumor necrosis factor-alpha (TNF-α), a driver of chronic inflammation. Unlike other therapies, MYMD-1 has been shown in these studies to selectively block TNF-α when it becomes overactivated in autoimmune diseases and cytokine storms, but not block it from doing its normal job of being a first responder to any routine type of moderate infection. MYMD-1’s ease of oral dosing is another differentiator compared to currently available TNF-α blockers, all of which require delivery by injection or infusion. No approved TNF inhibitor has ever been dosed orally. In addition, the drug is not immunosuppressive and has not been shown to cause the serious side effects common with traditional therapies that treat inflammation.

About MyMD Pharmaceuticals, Inc.

MyMD Pharmaceuticals, Inc. (Nasdaq: MYMD), a clinical stage pharmaceutical company committed to extending healthy lifespan, is focused on developing two novel therapeutic platforms that treat the causes of disease rather than only addressing the symptoms. MYMD-1 is a drug platform based on a clinical stage small molecule that regulates the immune system to control TNF-α, which drives chronic inflammation, and other pro-inflammatory cell signaling cytokines. MYMD-1 is being developed to delay aging, increase longevity, and treat autoimmune diseases. The Company’s second drug platform, Supera-CBD, is being developed to treat chronic pain, addiction and epilepsy. Supera-CBD is a novel synthetic derivative of cannabidiol (CBD) and is being developed to address and improve upon the rapidly growing CBD market, which includes both FDA approved drugs and CBD products not currently regulated as drugs.
