Cyclo Therapeutics Announces Completion of Enrollment in its Extension Protocol to the Phase I Trial to Evaluate Trappsol® Cyclo™ for the Treatment of Niemann-Pick Disease Type C

Cyclo Therapeutics, Inc. CTDH, a clinical-stage biotechnology company that develops cyclodextrin-based products for the treatment of Niemann-Pick Disease Type C and Alzheimer's Disease, today announced that it has completed patient enrollment in its Extension Protocol to the Phase I trial to evaluate the safety and tolerability of Trappsol^® Cyclo™ administered intravenously to Niemann-Pick Disease Type C1 (NPC1) patients.

"Today's announcement is another critical milestone for our company and the NPC community," said Company Chairman and CEO, N. Scott Fine. "All eligible patients who completed the Phase I trial entered the Extension Protocol, an important signal of how patients perceive benefits of receiving Trappsol^® Cyclo™ intravenously."

Niemann-Pick Disease Type C is a rare genetic disease affecting 1 in 100,000 live births globally. NPC affects every cell in the body due to a defect in the NPC1 protein which is responsible for cholesterol processing in the cell. NPC causes symptoms in the brain, liver, spleen, lung and other organs and often leads to premature death. There are no approved drug therapies for NPC in the United States and only one approved therapy in Europe.

"The Extension Protocol allows subjects who are resident in the United States to continue receiving our drug through home-based infusions, with qualified healthcare personnel oversight," said Sharon Hrynkow PhD, Cyclo Therapeutics' Chief Scientific Officer and Senior Vice President for Medical Affairs. "All foreign patients who participated in the trial also wish to continue on the drug: some are well underway in approved expanded access use programs, and others are now in process."

Data from the current study combined with those of the companion Phase I study (ClinicalTrials.gov NCT02939547) and the Phase I/II trial underway in Europe and Israel (ClinicalTrials.gov NCT02912793) will be used to inform the design of the Company's global pivotal trial. Cyclo Therapeutics, Inc. will meet with FDA in the first quarter of 2020 and expects to meet with EMA in the second quarter of 2020 to discuss the global pivotal development plan and timelines to initiate the pivotal trial.
