Rafael Holdings Announces Patent Licensing Agreement with MIT for “Small Molecules to Improve Myelination in ApoE4 positive Alzheimer’s Disease”

License of the MIT patent strengthens Rafael’s intellectual property around cyclodextrins as an Active Pharmaceutical Ingredient (API) in the treatment of ApoE4-positive Alzheimer’s Disease

NEWARK, N.J., April 22, 2026 (GLOBE NEWSWIRE) -- Rafael Holdings, Inc. (NYSE: RFL) today announced that its subsidiary, Cyclo Therapeutics, has entered into an exclusive licensing agreement with Massachusetts Institute of Technology (“MIT”) covering U.S. Patent No.12285440. This license covers the use of cyclodextrins in patients with Alzheimer's Disease (AD) who carry an ApoE4 genetic mutation, strengthening the company’s intellectual property portfolio around Trappsol^® Cyclo™ in this important AD patient population.

The ApoE4 gene variant is estimated to be present in 50-70% of patients with AD and is believed to be a key risk factor in the development early onset sporadic AD. Dysregulated cholesterol metabolism is believed to contribute to amyloid and tau pathology, especially in those patients with the ApoE4 gene variant, which has been shown to accelerate AD as it is the key lipids/cholesterol transporter in the brain.

The established mechanism of action (MOA) for Trappsol^® Cyclo™ could have a direct impact in ApoE4 positive patients as it has been shown to improve cholesterol transport between central nervous system (CNS) cells. Preclinical data suggest Trappsol^® Cyclo™ can improve delivery of cholesterol between CNS cells, reduce tau-pathology and improve learning/memory in mice.

“Securing this exclusive license from MIT represents a transformative milestone for our company and greater potential positive news for the millions of patients and their families affected by Alzheimer's disease. By combining the results of MIT's world-class foundational research with our clinical development expertise, we are well positioned to accelerate a potential breakthrough that addresses the underlying pathology of this devastating condition. This agreement underscores our commitment to pursuing the highest caliber of innovation to deliver life-changing therapies to patients in need," said Howard Jonas, CEO, Executive Chairman and Chairman of the Board of Rafael Holdings.

“With Phase 3 results from Transport NPC due in calendar Q3, 2026, we’re excited by Trappsol^® Cyclo™’s potential across multiple disease areas. Our NPC1 phase 3 study is the largest ever conducted in patients with NPC, yielding crucial clinical and safety data needed to advance the treatment paradigm for patients and families dealing with NPC " said Joshua Fine, COO of Rafael Holdings.
