- Manuscript published online ahead of print -
TORONTO, Aug. 12, 2016 (GLOBE NEWSWIRE) -- Cynapsus Therapeutics Inc. (NASDAQ:CYNA) (TSX:CTH), today announced that data from its CTH-105 Phase 2 trial of APL-130277 for the treatment of OFF episodes in patients with Parkinson's disease was published in the peer-reviewed journal Movement Disorders. The paper, titled "Sublingual Apomorphine (APL-130277) for the Acute Conversion of OFF to ON in Parkinson's Disease" by Robert A. Hauser, M.D., et al., was published electronically (http://onlinelibrary.wiley.com/doi/10.1002/mds.26697/full) ahead of print. The company had previously announced top-line data (http://content.equisolve.net/cynapsus/news/2014-11-19_Cynapsus_Therapeutics_Announces_Positive_Top_Line__92.pdf) from the CTH-105 trial in November of 2014.
Key findings from the manuscript include:
- A full ON response was achieved by 15 of 19 patients dosed (78.9%) with a mean dose of 18.4 mg
- All 15 responders (100.0%) achieved a full ON response within 30 minutes from the time of administration, and 6 of 15 (40.0%) achieved a full ON response within 15 minutes of administration
- The mean duration of ON time was 50 (SD 19.4) minutes with 9 of 15 (60.0%) patients remaining fully ON for 90 minutes
- A significant improvement in Movement Disorder Society's Unified Parkinson's Disease Rating Scale Part III (MDS-UPDRS) from baseline was observed at all time points with a mean maximum change of 18.9 points
- APL-130277 was safe and generally well-tolerated with no discontinuations because of adverse events
CTH-105 was a Phase 2 multicenter, open-label, clinical trial assessing APL-130277 in patients with Parkinson's disease who experience OFF episodes, with a total duration of OFF of at least two hours daily. OFF episodes were achieved by having patients take their last dose of levodopa the night before coming into the clinic. Patients were not allowed to take their first dose of levodopa or other PD medications in the morning, resulting in a morning OFF state. Patients were then given escalating doses of APL-130277 (at a minimum of three hours between doses) until ON was achieved, as documented by study staff, the patient and a clinician assessment of MDS-UPDRS. The MDS-UPDRS score was measured at 15, 30, 45, 60 and 90 minutes.
Albert Agro, Ph.D., author and chief medical officer of Cynapsus, said "The Phase 2 results published in this manuscript confirm the preliminary findings announced in 2014 that APL-130277 was highly effective at rapidly and safely converting patients from OFF to full ON. We look forward to continued validation of our approach to treating patients suffering with OFF episodes with top-line data from our Phase 3 efficacy study expected late in the third quarter or early fourth quarter of this year. We also intend to share longer-term safety data and file our new drug application in the first half of 2017."
Cynapsus is a specialty central nervous system pharmaceutical company developing and preparing to commercialize a fast-acting, easy-to-use, sublingual thin film for the on-demand management of debilitating OFF episodes associated with PD. The Company has successfully completed a Phase 2 clinical trial for its product candidate, APL-130277, a sublingual formulation of apomorphine hydrochloride, or apomorphine. Apomorphine is the only molecule approved for acute, intermittent treatment of OFF episodes for advanced PD patients, but is currently only approved as a subcutaneous injection in the United States. APL-130277 is a "turning ON" medication designed to rapidly, safely and reliably convert a PD patient from the OFF to the ON state while avoiding many of the issues associated with subcutaneous delivery of apomorphine. It is designed to convert all types of OFF episodes, including morning OFF episodes, often considered the most difficult to treat. Cynapsus has initiated its Phase 3 clinical program for APL-130277, relying on the abbreviated Section 505(b)(2) regulatory pathway in the United States, and the Company intends to submit an NDA in the first half of 2017.
