Cynapsus Therapeutics Provides Research Update for Parkinson’s Drug Candidate

Marketwire, June 24, 2022

TORONTO – Cynapsus Therapeutics Inc. (CTH: TSX-V), a specialty pharmaceutical company developing an improved dosing formulation of an approved drug used to treat the symptoms of Parkinson’s disease, today provided an update on the progress of its research activities on its lead drug candidate, APL-130277.

In providing the update, Anthony Giovinazzo, President and Chief Executive Officer, said: “I am pleased to report that our most recent drug prototypes have achieved a significant reduction in time to achieve maximum serum concentration (Tmax) of drug in the blood stream, as tested in validated animal models. As a result, we believe our latest prototypes may deliver more promising results in clinical testing in man. Over the next 6 months, our primary goal is to successfully complete a Phase 1 pharmacokinetic clinical study in healthy volunteers to further de-risk the project.”

Recent Developments

Improved Product Prototypes:

Over the past 3 months, Cynapsus continued development of new prototypes of APL-130277 in collaboration with an experienced cGMP thin-film manufacturer. Key improvements include advances in processing methodology, further increasing the speed of dissolution and the rate of absorption of the main active pharmaceutical ingredient, apomorphine hydrochloride. As a result, Cynapsus has a new lead-product candidate with a pharmacokinetic (PK) profile that is nearly identical to that of the FDA-approved injectable delivery of apomorphine hydrochloride. These results are important as they support our premise that APL-130277 thin-film strips provide efficacious serum levels that match closely the US FDA criteria for a 505(b)(2) submission.

Successful Meeting with US Food and Drug Administration (FDA):

In April, Cynapsus held a successful Pre-IND Meeting with the US FDA in Washington, DC, to discuss preliminary clinical plans for APL-130277, an apomorphine thin film strip formulation for the rescue of patients experiencing “OFF” periods in Parkinson’s disease. The outcome of the meeting was positive, and the Company expects to enter its first human clinical trials of APL-130277 in the second half of 2011.

Refined Clinical Trial Plans and Vendor Selection:

Over the past 3 months, Request-for-Proposals were sent to several experienced and qualified US-based Contract Research Organizations (CRO) who have expressed interest in conducting upcoming Phase 1 and Pivotal clinical studies. Site visits are planned and CRO selection is expected to occur in the next couple of months. Vendors for all other clinical services such as PK analysis and stats, report writing, etc. will also be made shortly.

About Parkinson’s Disease and APL-130277

In the United States alone, approximately 4 million new Americans will turn 65 each year for the next 19 years. This demographic is the primary age group for development of neurodegenerative diseases such as Alzheimer’s and Parkinson’s disease. It is estimated that there are approximately 6 million Parkinson’s disease patients in the world today.

Discovery of disease modifying therapies for chronic brain conditions such as Parkinson’s disease and Alzheimer’s disease based on early diagnosis, genetic manipulation, and/or cell therapy are more than 10 to 15 years away. Further research will be required to make such therapies practical, economical, and broadly available. As a result, effective and economical therapies that relieve symptoms, such as APL 130277, will remain a mainstay in treating patients and will address substantial unmet medical needs.

For patients with Parkinson’s disease, Apomorphine is a fast-acting, effective dopamine agonist to treat off episodes, i.e. periods when chronic Parkinson’s patients experience impaired movement or speaking capabilities. Apomorphine is currently approved by the US Food and Drug Administration (FDA) and the European Medicines Agency (EMEA), but is currently only available by subcutaneous injection.

APL-130277 has the potential to be the first marketed convenient oral (sublingual) formulation of apomorphine, a drug proven to work even in the most severe cases of Parkinson’s disease in which other drugs have diminished effect. APL-130277 is being developed as a once to three times a day rescue therapy, to be used adjunctive to levodopa combination therapies.

As a drug development project, APL-130277 has a lower risk profile than a New Chemical Entity given that the regulatory path is shorter and well-defined, the cost to an approvable New Drug Application (NDA) is relatively low (estimated at approximately $20 million), and the active compound has a well known efficacy and safety profile. If APL 130277 demonstrates “therapeutic equivalence” in its abbreviated 2 year clinical program, the Company, or a pharmaceutical partner, would be allowed under the US FDA regulations, to submit a New Drug Approval request, based on the 505b(2) criteria. These criteria would recognize the subcutaneous injection (NDA 21-264) as the reference listed drug to which APL 130277 would draw safety and efficacy data and would be compared by the US FDA.

About Cynapsus Therapeutics

Cynapsus is a specialty pharmaceutical company developing an improved dosing formulation of an approved drug used to treat the symptoms of Parkinson’s disease. Parkinson’s disease is a chronic and progressive neurodegenerative disease that impacts motor activity, and its prevalence is increasing with the aging of the population. It is estimated that between 25 percent and 50 percent of patients experience “off episodes” in which they have impaired movement or speaking capabilities. Current medications only control the disease’s symptoms, and most drugs become less effective over time as the disease progresses.

Cynapsus’ lead drug candidate, APL-130277, is an easy-to-administer, fast-acting and oral reformulation of an approved drug, apomorphine, used to rescue patients from off episodes. Cynapsus is focused on rapidly maximizing the value of APL-130277 by completing pivotal studies in advance of a New Drug Application expected to be submitted in 2013 or 2014. The Company anticipates out-licensing to an appropriate pharmaceutical partner before such an application is submitted.
