MyMD seeks to disrupt the $31 billion global market for rheumatoid arthritis (RA) drug therapies with MYMD-1, which could potentially prove safer, more effective and better tolerated than current options

Submission of Investigational New Drug (IND) application and protocols for a Phase 2 RA study planned for second half of 2022

BALTIMORE--(BUSINESS WIRE)-- MyMD Pharmaceuticals, Inc. (Nasdaq: MYMD) (“MyMD” or “the Company”), a clinical stage pharmaceutical company committed to extending healthy lifespan, today announced positive new preclinical study data demonstrating the potential effectiveness of MYMD-1 for the treatment of rheumatoid arthritis (RA). MYMD-1 demonstrated a significantly greater anti-inflammatory effect than current TNF-alpha inhibitors on the market, the top three of which represent an estimated $31 billion market (based on 2020 revenues)1.

The comparative study of arthritis, using the CAIA model2, was conducted and analyzed by Charles River Laboratories International, a full-service contract research organization for drug discovery and development. Study results showed that MYMD-1 inhibited inflammation more effectively in the RA model by 30% and 70% of the top two marketed drugs, respectively.

“We are excited about the impressive new data we are announcing today that shows a highly favorable comparison of our lead drug candidate MYMD-1 to the gold standard rheumatoid arthritis drug therapies currently on the market today. A small fraction of this enormous $31 billion market represents a highly attractive opportunity for MyMD,” said Chris Chapman, M.D., President, Director and Chief Medical Officer of MyMD.

“Utilizing the strong proof-of-concept and efficacy data from our pre-clinical model, we are preparing to submit to the FDA an Investigational New Drug (IND) application for MYMD-1 as treatment for RA, along with protocols for a Phase 2 study, in the second half of this year.”

In addition to the greater efficacy shown in the preclinical model of RA, we believe that MYMD-1 holds significant advantages over current anti-TNF-alpha therapies:

  • Smaller molecular size with easy access throughout the body, including the brain;
  • Selective inhibition of TNF-alpha production by lymphocytes involved in autoimmune disease, but not macrophages involved in front line immune protection against bacteria and viral infections;
  • Not shown to cause serious side effects in preclinical studies that is common with traditional therapies that treat inflammation;
  • Simultaneous inhibition of pro-inflammatory cytokines TNF-alpha, IL-6 and IL-17; and
  • Ease of oral dosing rather than by needle injection. Drug candidate MYMD-1 is the only TNF-alpha inhibitor that is dosed orally.

MyMD is currently conducting a Phase 2 clinical trial of MYMD-1 as a therapy for delaying aging and expanding healthy lifespan. The primary endpoint for the Phase 2 double-blind, placebo-controlled clinical trial is to achieve a reduction in circulating levels of TNF-alpha within 28 days of therapy.

In addition to aging and rheumatoid arthritis, MYMD-1’s distinct action in regulating the immune system and treating chronic inflammation is being developed for the treatment of multiple sclerosis (MS), diabetes, and inflammatory bowel disease.

About Rheumatoid Arthritis

Rheumatoid arthritis is a chronic autoimmune disease and an inflammatory form of arthritis. The disorder preferentially attacks the joints and is characterized by inflammation and bone erosion. In the progression of RA, joints are infiltrated by white blood cells that produce the pro-inflammatory cytokines TNF-alpha, IL-6 and IL-17. Rheumatoid arthritis is the most common form of autoimmune arthritis, affecting more than 1.3 million Americans4 and occuring at any age. Studies have determined that the number of people suffering from rheumatoid arthritis may rise to over 78 million by 20405.

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 pre-clinical 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 and COVID-19- associated depression. 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.

2 Animal models of arthritis mimic many of the features of arthritis in humans and have been used successfully in establishing proof of concept for new treatment compounds. Of the animal models available, the murine Collagen Antibody-Induced Arthritis (CAIA) model is modeled after RA, and is widely used because of the similar putative etiology to human disease. Moreover, microscopic changes associated with rheumatoid arthritis (e.g., inflammation, bone erosion, and bone degeneration) are observed in CAIA control animals.

3 Predicted Humira response was calculated based on previous comparisons of Enbrel vs. Humira in the same CAIA model during a previous experiment by Charles River.
