Cyclo Therapeutics Announces First Patient Dosed in Phase 2b Study of Trappsol® Cyclo™ for the Treatment of Early Alzheimer’s Disease

– Biologic similarities demonstrated between Niemann-Pick Disease Type C and Alzheimer’s disease, including cholesterol accumulation in regions of the brain, elevated levels of Tau in CSF, and amyloid plaques in the brain, bolsters rationale for studying Trappsol^® Cyclo™ for the treatment of early Alzheimer’s disease

Cyclo Therapeutics, Inc. (Nasdaq: CYTH) (“Cyclo Therapeutics” or the “Company”), a clinical stage biotechnology company dedicated to developing life-changing medicines through science and innovation for patients and families living with diseases, today announced the first patient has been enrolled and dosed in its Phase 2b study of Trappsol^® Cyclo™ for the treatment of early Alzheimer’s disease (AD), targeting the disrupted lipid pathways and the reduction of amyloid beta and tau.

“The start of this study is a significant milestone for our Company and the Alzheimer’s disease community. Based on the encouraging results Trappsol^® Cyclo™ has demonstrated to date we believe we are well-positioned to address the unmet medical need that patients, families and physicians are facing,” commented Lise Kjems M.D. PhD. Chief Medical Officer.

The Phase 2b study is a U.S. multicenter, randomized, placebo-controlled, double-blind, parallel group, 6-month study evaluating the safety, tolerability, and potential efficacy of monthly Trappsol^® Cyclo™ infusions in patients with early Alzheimer’s disease. The study will enroll approximately 120 patients who have shown evidence of progressive cognitive decline in the last year as determined by serial cognitive test scores, if available, or patient or informant/caregiver/study partner report as documented by the Investigator. Enrolled patients will be randomized across three study arms: 500 mg/kg or 1000 mg/kg of Trappsol^® Cyclo™ and placebo. The study will consist of a screening period, treatment period up to 24 weeks, and a safety follow-up period.

Trappsol^® Cyclo™ is the Company’s proprietary formulation of hydroxypropyl beta cyclodextrin, and in multiple clinical studies, has shown encouraging results to effectively manage the transportation of cholesterol, a known defect in neurodegenerative diseases. Many of the known risk factors for Alzheimer’s disease are associated with cholesterol metabolism.

Cyclo Therapeutics is currently testing the same investigational Trappsol^® Cyclo™ drug in a Phase 3 clinical trial (TransportNPC™) and a long-term extension study for the treatment of Niemann-Pick disease Type C1, a rare, fatal and progressive genetic disorder. Taking the place of the defective NPC1 protein, Trappsol^® Cyclo™, with its cyclic structure, facilitates the transport of accumulated cholesterol out of cellular lysosomes so it can be further processed and excreted out of cells. With the biologic similarities demonstrated between Niemann-Pick disease Type C1 and Alzheimer’s disease, including cholesterol accumulation in regions of the brain, elevated levels of Tau in cerebrospinal fluid (“CSF”), and amyloid plaques in the brain, the Company believes Trappsol^® Cyclo™ has significant potential to be an effective treatment option for Alzheimer’s disease.

About Alzheimer’s Disease

Alzheimer’s disease is a progressive neurologic disorder that causes the brain to shrink (atrophy) and brain cells to die. Estimates vary, but experts suggest that more than 5.5 million Americans, most of them age 65 or older, may have dementia caused by Alzheimer’s. The early signs of the disease include forgetting recent events or conversations. As the disease progresses, a person with Alzheimer’s disease will develop severe memory and thinking skills impairment, then lose ability to learn, reason, make judgments, communicate and carry out daily activities. Medications may temporarily improve or slow progression of symptoms, however there is currently no treatment that cures Alzheimer’s disease or alters the disease process in the brain.

About Cyclo Therapeutics

Cyclo Therapeutics, Inc. is a clinical-stage biotechnology company dedicated to developing life-changing medicines through science and innovation for patients and families living with disease. The Company’s Trappsol^® Cyclo™, an orphan drug designated product in the United States and Europe, is the subject of four formal clinical trials for Niemann-Pick Disease Type C, a rare and fatal genetic disease, (www.ClinicalTrials.gov NCT02939547, NCT02912793, NCT03893071 and NCT04860960). The Company is conducting a Phase 2b clinical trial using Trappsol^® Cyclo™ intravenously in early Alzheimer’s disease based on encouraging data from an Expanded Access program for Alzheimer’s disease (NCT03624842). Additional indications for the active ingredient in Trappsol^® Cyclo™ are in development. For additional information, visit the Company’s website: www.cyclotherapeutics.com.
