Silo Pharma Enters into Letter of Intent to Form Joint Venture with Hoth Therapeutics to Develop Obesity Treatment Targeting $16 Billion Global Market

Technology Co-Developed by the U.S. Department of Veterans Affairs and Emory University

NEW YORK, June 25, 2025 (GLOBE NEWSWIRE) — Silo Pharma, Inc. (Nasdaq: SILO) (“Silo” or the “Company”), a developmental stage biopharmaceutical company focused on novel therapeutics and drug delivery systems, today announced that it has entered into a non-binding letter of intent to form a strategic 50:50 joint venture with Hoth Therapeutics, Inc. (Nasdaq: HOTH) to develop and commercialize a potential treatment for obesity and metabolic disease based on technology Hoth has exclusively licensed from the U.S. Department of Veterans Affairs (VA) that was co-developed by the VA and Emory University.

The novel therapeutic platform centers on glial cell line-derived neurotrophic factor (GDNF), a VA-invented biologic with demonstrated anti-obesity effects and metabolic regulation in preclinical models. The platform is protected under U.S. Patent No. 10,052,362 and targets multiple high-burden conditions, including non-alcoholic fatty liver disease (NAFLD), type 2 diabetes, and central obesity.

“With obesity at epidemic levels and no curative therapies available, we believe the VA’s biologic GDNF is potentially a game-changer,” said Eric Weisblum, CEO of Silo Pharma. “We believe that our potential JV collaboration with Hoth aligns with our mission to accelerate groundbreaking science into human trials.”

“This VA-originated obesity technology has the potential to disrupt a $16 billion market and deliver life-changing impact for millions, including veterans disproportionately affected by metabolic disorders,” added Robb Knie, CEO of Hoth Therapeutics. “We are proud to partner with Silo Pharma in an effort to bring this innovation to the public.”

Deal Highlights:

Unmet Need:
Obesity affects over 40% of U.S. adults and is a leading risk factor for diabetes, cardiovascular disease, and liver failure. Veterans are especially impacted due to chronic inflammation, PTSD-linked metabolic disruption, and access challenges to effective care. There are no approved curative biologics targeting the neuroinflammatory root of obesity, a gap that this VA-originated technology is uniquely positioned to fill.

Strategic Alignment:
