A Study to Assess the Bioavailability and Adhesion of Selegiline TDS in Healthy Subjects

This is a single-dose, single-center, open-label, randomized crossover study (2 treatments, 2 periods and 4 sequences) of a generic test formulation of Selegiline TDS 6 mg/24 hours with the comparator EMSAM® TDS 6 mg/24 hours, with at least 56 days washout period, recruiting around 92 healthy male and female subjects. For each study period, subjects will be admitted and confined in the clinical study site the night before the study day from at least 10 hours before dosing and they will be discharged once all PK, safety and tolerability are completed at 72 hours after dosing. Subjects will be required to return for subsequent PK, safety and tolerability at 84-hours post-dosing. The clinic will follow up by telephone 7 ± 3 days after subject completion of the study. Trained study staff will also examine the patch application sites at scheduled time points and will score any skin reactions using standardized assessment scales. In addition, photographs of the patch application site will be taken to document adhesion status while the patch is being worn. PK blood samples will be collected before dosing and at 1, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 25, 27, 28, 32, 36, 40, 44, 48, 60, 72 and 84 hours after dosing. Furthermore, the overall safety of the test product will be compared with that of the comparator product by monitoring and recording any adverse events, side effects, or discomfort experienced by subjects during the study.
