MYMD-1 demonstrated favorable safety and tolerability profile across multiple doses, with no clinically relevant adverse events, supporting advancement of the compound for Sarcopenia and Rheumatoid Arthritis

MyMD Pharmaceuticals, Inc.^® (Nasdaq: MYMD) (“MyMD” or “the Company”), a clinical stage pharmaceutical company committed to developing novel therapies for age-related diseases, autoimmune and inflammatory conditions, today announced the publication of results from a Phase 1 study of oral tumor necrosis factor-alpha (TNF-α) inhibitor, MYMD-1^® (Isomyosamine), in peer-reviewed journal, Drug Research. The randomized, double-blind, placebo-controlled study, intended to evaluate the safety, tolerability, and pharmacokinetic profile of MYMD-1 in healthy adults, found that single daily doses for 3 days and multiple daily doses for 6 days were safe and well tolerated in healthy subjects. The study used single daily doses of 150 mg, 300 mg, and 450 mg, respectively, and multiple daily doses of 600 mg. There were no new or unexpected safety findings and no clinically relevant or severe adverse events reported.

MYMD-1 is an oral next-generation TNF-α inhibitor with the potential to transform the way that TNF-α based autoimmune diseases are treated. Its ease of oral dosing is a significant differentiator compared to currently available TNF-α inhibitors, all of which require delivery by injection or infusion. MYMD-1 has also been shown to selectively block TNF-α where it is overactivated without preventing it from doing its normal job of responding to routine infection. In addition, it has not been shown to cause serious side effects common with traditional immunosuppressive therapies that treat inflammation.

“As the first TNF-α inhibitor to be dosed orally, publication of these data confirm our belief that MYMD-1 may one day offer a new treatment option for patients not served by currently available therapies,” said Chris Chapman MD, President, Director, and Chief Medical Officer at MyMD Pharmaceuticals. “We look forward to upcoming Phase 2 results in sarcopenia and to advancing our MYMD-1 programs in other autoimmune disorders including rheumatoid arthritis and Hashimoto’s thyroiditis.”

MYMD-1 is currently being evaluated in Phase 2 studies for sarcopenia/frailty, a result of the aging process, with data expected in 4Q 2022. MYMD-1 has the potential to be the first drug approved by FDA for the condition. The company also expects to initiate a clinical program in rheumatoid arthritis (RA), which affects more than 1.3 million Americans.¹ Along with the growing aging population, autoimmune diseases like RA are becoming more prevalent. The National Institutes of Health estimates that autoimmune diseases overall may affect as many as 24 million Americans.²

About MYMD-1

MYMD-1, an oral selective inhibitor of tumor necrosis factor-alpha (TNF-α), a driver of chronic inflammation, is being studied to slow the aging process, prevent sarcopenia and frailty, and extend healthy lifespan. MYMD-1 has shown effectiveness in pre-clinical and clinical studies in regulating the immune system. 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 FDA-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. 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.

About MyMD Pharmaceuticals

MyMD Pharmaceuticals, Inc. (Nasdaq: MYMD), is a clinical stage biopharma company developing groundbreaking therapies for the treatment of serious and debilitating autoimmune and inflammatory diseases. MyMD’s lead clinical candidate, MYMD-1®, is an orally available next-generation TNF-alpha inhibitor with the potential to transform the way that TNF-alpha based diseases are treated. MYMD-1®, with its small molecule design, improved safety profile and ability to cross the blood brain barrier, has the promise to provide meaningful therapeutic solutions to patients not served by current TNF-alpha inhibitors and as a potential therapy for CNS-based inflammatory and autoimmune diseases. MYMD-1 has demonstrated the potential to slow the aging process and extend healthy lifespan. The company is evaluating MYMD-1® in Phase 2 studies for sarcopenia/frailty, a result of the aging process, as well as early-stage trials for rheumatoid arthritis (RA), with the potential to expand into other applications. MyMD’s second therapeutic candidate is Supera-CBD, a novel, synthetic, non-toxic cannabidiol (CBD) analog that is 8000 times more potent a CB2 agonist (activator) than plant-based CBD. In addition to its potential role in managing addiction, anxiety, chronic pain and seizures, Supera-CBD has also been shown to have anti-inflammatory effects.
