FDA Accepts MyMD Pharmaceuticals’ Investigational New Drug Application (IND) for Phase 2 Study of oral TNF-α inhibitor MYMD-1® in Rheumatoid Arthritis (RA)

- Next-generation and first oral TNF-α inhibitor, which completed Phase 2 study for age-related condition sarcopenia, represents a potentially groundbreaking advance in the treatment of RA and disruption of a $41 billion industry

- Acceptance follows statistically significant Phase 2 data in sarcopenia showing MYMD-1 reduced TNF-α and other inflammatory markers common to RA, while demonstrating safety and tolerability

- MyMD now advancing 3 clinical programs for MyMD-1 in chronic inflammatory conditions including Sarcopenia, RA and Hashimoto’s Thyroiditis

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 the U.S. Food and Drug Administration (FDA) has accepted the Company’s Investigational New Drug Application (IND) to evaluate the safety, efficacy, pharmacodynamics and pharmacokinetics of oral TNF-α inhibitor MYMD-1^® in patients with active rheumatoid arthritis (RA). The application was based on preclinical data showing that MYMD-1 significantly reduced swelling and other clinical arthritis measures compared to widely used RA therapy, Enbrel® (etanercept).¹ The Company plans to initiate discussions with CRO vendor IQVIA on timing of a Phase 2 study in this indication.

MYMD-1 is an oral, next-generation TNF-α inhibitor with the potential to transform the way TNF-α based diseases are treated due to its selectivity and ability to cross the blood brain barrier. 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 action where it is overactivated without preventing it from doing its normal job of responding to routine infection. MYMD-1 is doubly effective at inhibiting inflammation by blocking both TNF-a and IL-6 activity, whereas currently approved anti-TNF and anti-IL-6 treatments for RA can only target one or the other. In addition, in early clinical studies it has not been associated with serious side effects known to occur with traditional immunosuppressive therapies that treat inflammation.

“FDA acceptance of an IND in RA for our next-generation oral TNF-α inhibitor, MYMD-1, is our most significant milestone as it adds substantial momentum to our clinical program with sufficient funding and targets one of the largest potential market opportunities,” said Chris Chapman, M.D., president, director, and chief medical officer of MyMD. “We are excited to initiate discussions with our CRO regarding a Phase 2 clinical trial in RA and believe the statistically significant biomarker data from the Phase 2 study in sarcopenia show MYMD-1 has the potential to disrupt the TNF-α inhibitor market and offer therapeutic benefit to patients with a range of chronic inflammatory conditions.”

Recently, MyMD announced positive, statistically significant Phase 2 study results in participants with sarcopenia/frailty which showed MYMD-1 reduced TNF-α, IL-6 and sTNFR1, biomarkers which are common to a number of chronic inflammatory diseases, and met all safety and tolerability endpoints. The Company plans to initiate Phase 3 trials. If approved, MYMD-1 has the potential to be the first drug approved by FDA for the sarcopenia, an age-related decline in muscle mass and physical function which leads to greater risk of hospitalization, disability, and death.

“This is significant news and suggests MYMD-1 may hold promise to be the first oral TNF-α inhibitor and a potential future treatment for rheumatoid arthritis,” said clinical researcher, rheumatologist and past President of the Florida Society of Rheumatology, Robert W. Levin, MD. “There remains a need for new oral therapies with novel mechanism of action for patients not served by current options and I look forward to leading upcoming Phase 2 studies of MYMD-1 to determine its full potential in RA. I look forward to reviewing the study outcomes.”

About Rheumatoid Arthritis

Rheumatoid arthritis, an autoimmune disorder characterized by inflammation (painful swelling) and bone erosion, affects nearly 14 million people worldwide, including 1.5 million Americans.² Although typically associated with older adults, RA can occur at any age, and it is three times more likely to affect women than men.³ TNF-α has played a central role in treatments for RA since 1998, all of which are administered via injection or infusion.

Furthermore, the burden to patients, care providers and society is striking, with an estimated annual cost of $39.2 billion.⁴ The price tag includes healthcare costs, loss of employment, costs to employers, government and caregivers as well as costs associated with a deterioration of quality of life, among other societal costs.

About MYMD-1

MYMD-1, a next generation, oral selective inhibitor of tumor necrosis factor-alpha (TNF-α), a driver of chronic inflammation, and this drug is being studied to slow the aging process, prevent sarcopenia and frailty, extend healthy lifespan, as well as treat rheumatoid arthritis. 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 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. In addition, it has not been shown to cause serious side effects common with traditional immunosuppressive therapies that treat inflammation.

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-α inhibitor with the potential to transform the way that TNF-α 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-α inhibitors and as a potential therapy for CNS-based inflammatory and autoimmune diseases. The company has completed Phase 2 studies of MYMD-1^® 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. The U.S. Drug Enforcement Administration (DEA)’s scientific review concluded Supera-CBD will not be considered a controlled substance or listed chemical under the Controlled Substances Act (CSA) and its governing regulations or require scheduling during development. 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.
