Fully funded multi-center study initiated at University of Florida to further explore efficacy of isomyosamine for preventing progressive muscle loss and frailty

Study builds on positive results achieved in earlier Phase 2a trial

TNF-alpha inhibitor market estimated at $40+ billion with no FDA-approved oral treatments

BALTIMORE, MD, USA I February 25, 2025 I TNF Pharmaceuticals, Inc. (Nasdaq: TNFA) (“TNF” or the “Company”), a clinical stage biopharmaceutical company committed to developing novel therapies for autoimmune and inflammatory conditions, today announced the initiation of a fully funded Phase 2b clinical trial evaluating oral TNF-alpha (TNF-α) inhibitor drug candidate isomyosamine as a treatment for chronic inflammation associated with muscle loss (frailty or sarcopenia) in patients who have undergone hip or femur fracture repair surgery.

“The initiation of our Phase 2b isomyosamine trial marks an important milestone in our mission to develop a novel science for immuno-metabolic regulation and increased longevity,” said Mitchell Glass, M.D., President and Chief Medical Officer of TNF. “A deeper exploration of isomyosamine’s efficacy will be studied in patients with acute post-surgical inflammation and complications from hip or femur fractures. In addition to further functional decline, these patients face a higher likelihood of complications that can compromise or delay recovery and are associated with higher healthcare costs.”

According to Jay Magaziner, Ph.D., Director of the Center for Research on Aging at the University of Maryland and founder of the Baltimore Hip Studies project that evaluates outcomes after hip fractures in older patients, “After hip fracture, older patients can precipitously lose bone, muscle, and function, which is associated with a systemic inflammatory response. If we can block this inflammatory response, we have a chance to reduce the amount of muscle loss and the associated functional loss, leading to better outcomes in hip fracture among older persons.”

The upcoming Phase 2b trial to be initiated at the University of Florida is a randomized, placebo-controlled, double-blind study evaluating the efficacy and safety of isomyosamine in reducing inflammation in patients with sarcopenia undergoing fracture repair. Sixty patients will be treated with isomyosamine or placebo for up to 90 days after surgery. The study will measure the extent and time course of recovery to evaluate functional improvement, comparing active dosing to placebo.

The site’s principal investigator is Porter Young, M.D., an assistant professor of orthopaedic surgery and rehabilitation at the University of Florida. His research centers on acetabulum fractures, pelvis fractures, periarticular fractures and management of polytrauma patients.

Isomyosamine 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. Isomyosamine 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. 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.

Burden of Sarcopenia

Sarcopenia (ICD-10-CM code M62.84) affects approximately 10% to 16% of the elderly worldwide.1 It is also estimated to affect more than 1 in every 10 young adults of most ethnicities.2 Based on conservative calculations, at least 50 million people were affected by sarcopenia in 2018, and the disease is projected to affect over 200 million over the next four decades due to the growing elderly population.3

The sarcopenia treatment market is estimated to be $3.07 billion in 2024 and is expected to grow at a compound annual growth rate (CAGR) of 4.5% to $4.0 billion by 2029.4 With no FDA-approved treatments for sarcopenia, the estimated $40+ billion in related hospitalization costs is a considerable economic burden on the U.S. healthcare system.5

The global market value for TNF inhibitor drugs was estimated to be $39.7 billion in 2024. Growing at an expected CAGR of 3.6% for the next five years, the TNF inhibitor market is expected to reach $47.3 billion by 2029.6

About Isomyosamine

Isomyosamine is a novel plant alkaloid small molecule shown to regulate the immuno-metabolic system through the modulation of numerous pro-inflammatory cytokines including TNF-alpha (TNF-α), an immune cell signaling protein and inflammatory cytokine responsible for inducing and maintaining the inflammatory process. TNF-α is located upstream of a cascade of molecular signals that induces inflammation and helps activate the process of aging. Many in vivo and in vitro studies have shown that TNF-α plays a causative role in the pathogenesis of various age-related diseases.

About TNF Pharmaceuticals, Inc.

TNF Pharmaceuticals, Inc. (Nasdaq: TNFA), 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. Isomyosamine 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. Isomyosamine is being developed to treat diseases and disorders marked by acute or chronic inflammation. 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.
