- Solid clinical and operational execution demonstrated with advancement of Trappsol^® Cyclo™ for Niemann-Pick Disease Type C1 (NPC1) with commencement of pivotal study (TransportNPC™) and start of commercial-scale manufacturing

- Progression of Phase 2 study for Alzheimer’s Disease asset towards investigational new drug application (IND) filing remains on track for H2 2021

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 reported its financial results for the second quarter of 2021, and provided a business update.

“Our second quarter was marked by solid execution across multiple fronts. On the heels on positive topline results from our Phase 1/2 study in NPC and the recently announced positive long-term safety and efficacy from our Phase 1 open-label extension study, we have continued to build on that momentum and initiated our pivotal Phase 3 study in NPC as well as commenced commercial-scale manufacturing for Trappsol^® Cyclo™. Additionally, with the positive feedback from the FDA supporting our strategy moving forward with our Alzheimer’s Disease program, we continue to advance towards multiple catalytic milestones ahead. I am incredibly pleased with our team and our progress and believe we are poised for an exciting remainder of the year and beyond,” commented N. Scott Fine, CEO of Cyclo Therapeutics.

Recent Highlights

• Announced new positive safety and efficacy data from ongoing Phase 1 open-label extension study of Trappsol^® Cyclo™ for the treatment of NPC;
• Commenced the commercial-scale production of batches of Trappsol^® Cyclo™ which will be used to support ongoing TransportNPC™ study in NPC1, the upcoming Phase 2 study in Alzheimer’s Disease, and the Company’s active compassionate use program;
• Commenced site activation and patient enrollment for the TransportNPC™ study evaluating Trappsol^® Cyclo™ for the treatment of NPC1;
• Appointed Lori McKenna Gorski as Global Head of Patient Advocacy. Ms. Gorski is a leading biotechnology executive with more than 20 years of experience specializing in patient advocacy for rare disease communities, including lysosomal disorders; and
• Received feedback from the FDA supporting the Company’s development strategy to submit an IND application for a Phase 2 study of Trappsol^® Cyclo™ in the treatment of early Alzheimer’s Disease, following a positive Type B interaction.

Trappsol^® Cyclo™ Clinical Program Update

Trappsol^® Cyclo™ is a proprietary formulation of hydroxypropyl beta cyclodextrin, used intravenously (IV) and currently in development for the treatment of NPC, a rare genetic disorder causing cholesterol accumulation in lysosomes of cells, organ dysfunction and premature death.

Niemann-Pick Disease Type C1 Development Program

In June 2021, the Company commenced the TransportNPC™ study evaluating Trappsol^® Cyclo™ for the treatment of NPC1, a rare, progressive and fatal genetic disorder. Initial sites are in the U.S.

The pivotal Phase 3 study is a randomized, double-blind, placebo-controlled, parallel group, multicenter study designed to evaluate the safety, tolerability, and efficacy of 2,000 mg/kg doses of Trappsol^® Cyclo™ administered intravenously and standard of care (SOC), compared to placebo administered intravenously and SOC alone, in patients with NPC1. The Phase 3 study intends to enroll at least 93 pediatric (age 3 years and older) and adult patients with NPC1 in at least 23 study centers in 9 countries. Eligible patients will be randomized 2:1 to receive either Trappsol^® Cyclo™ or a placebo. Randomization will not be constrained based on patient age, nor will patient enrollment be gated by patient age. The study duration is 96 weeks and includes an interim analysis at 48 weeks.

The Company recently received a positive opinion from the Paediatric Committee (PDCO) of the EMA and agreement on its Paediatric Investigation Plan (PIP) for Trappsol^® Cyclo™. The PIP opinion from PDCO endorsed the clinical program to evaluate the safety, tolerability and efficacy of Trappsol^® Cyclo™ in patients from 3 to less than 18 years of age with NPC in the randomized study, and in addition, to include a single-arm open-label sub-study of patients from birth to less than 3 years of age with NPC Type C1 irrespective of symptoms to evaluate safety and to obtain descriptive data on global disease severity and the response to Trappsol^® Cyclo™. The sub-study in patients from birth to less than 3 years of age will only be conducted in the EU and countries following EMA guidelines.

Additionally, Cyclo Therapeutics recently presented new long-term safety and efficacy data from its ongoing Phase 1 open-label extension study evaluating Trappsol^® Cyclo™ for the treatment of NPC. The data seen to-date provide additional support for the capacity of Trappsol^® Cyclo™ to stabilize disease progression with home-based intravenous infusions as well as for a favorable safety profile of more than two years in NPC.

Cyclo Therapeutics received Orphan Drug Designation for Trappsol^® Cyclo™ to treat NPC1 in both the U.S. and EU and Fast Track and Rare Pediatric Disease Designations in the U.S. The Rare Pediatric Disease Designation is one of the chief requirements for sponsors to receive a Priority Review Voucher in the U.S. upon marketing authorization.

Alzheimer’s Disease Asset

Cyclo Therapeutics is also planning to evaluate Trappsol^® Cyclo™ for the treatment of Alzheimer’s Disease, targeting the reduction of amyloid beta and tau. As part of a Type B interaction with the FDA, Cyclo Therapeutics received positive feedback supporting the Company’s development strategy to submit an IND application for a Phase 2 study of intravenous Trappsol^® Cyclo™ in the treatment of early Alzheimer’s disease. The Company is on track to file its IND for a Phase 2 study of Alzheimer’s disease before year-end 2021.

Expected Upcoming Milestones

• Target filing IND in H2 2021 for potential Phase 2 study evaluating Trappsol^® Cyclo™ for the treatment of Alzheimer’s Disease.

Summary of Financial Results for Second Quarter 2021

Net loss for the quarter ended June 30, 2021 was approximately $3.6 million. Research and development expenses increased 54% to $2.6 million for the three months ended June 30, 2021, from $1.7 million for the three months ended June 30, 2020. The increase in research and development expense is due to increased activity in the Company’s international clinical program and U.S. clinical trials. The Company expects research and development costs to further increase in 2021 as we continue to seek regulatory approval for the use of Trappsol^® Cyclo™ in the treatment of NPC and Alzheimer’s disease.

The Company ended the quarter with approximately $11.4 million of cash.
