CTD Holdings Scientific Advisory Board Endorses Alzheimer's Disease as Next Indication for Company's Trappsol® Cyclotm Drug Development Program

CTD Holdings, Inc. (OTCQB: CTDH), a clinical-stage biotechnology company that develops cyclodextrin-based products for the treatment of disease with unmet medical need, today announced that the Company's Scientific Advisory Board endorsed Alzheimer's Disease as the company's next drug development indication. The Scientific Advisory Board met via videoconference on July 17, 2019. The endorsement was made based on the company's data from an ongoing expanded access program in late-onset Alzheimer's Disease with Trappsol^® Cyclotm and on data from two ongoing trials using Trappsol^® Cyclotm in Niemann-Pick Disease Type C, a rare genetic disease which may also lead to cognitive decline. The expanded access program in late-onset Alzheimer's Disease is now in its second year. CTD's Niemann-Pick Disease Type C trials and the expanded access program in Alzheimer's are based on intravenous administration of the drug.

CTD Chairman and CEO N. Scott Fine said, "CTD is grateful to the Scientific Advisory Board for its insights and its work. We will move forward to build and launch a clinical trial in Alzheimer's Disease."

The Scientific Advisory Board is led by two Co-Chairs: Rita Colwell, PhD, Distinguished University Professor both at the University of Maryland at College Park and at Johns Hopkins University Bloomberg School of Public Health, and former Director of the National Science Foundation, and Sharon Hrynkow, PhD, CTD's Chief Scientific Officer and Senior Vice President for Medical Affairs.

Scientific Advisory Board members are:

M. Flint Beal, MD, University Professor of Neurology and Neuroscience in the Department of Neurology and Neuroscience at the Weill Medical College of Cornell University - New York Presbyterian Hospital;

Caroline Hastings, MD, Pediatric Hematologist/Oncologist and senior clinician-scientist and educator at the UCSF Benioff Children's Hospital, Oakland CA; and

Benny Liu, MD, Associate Division Chief of Gastroenterology at Highland Hospital in Oakland, CA and an Assistant Clinical Professor at the University of California, San Francisco (UCSF).
