Brief Summary:
A Phase 1, Randomized, Open-Label, 3-Way Crossover, Pilot, Pharmacokinetic Study to Evaluate the Steady State Pharmacokinetics of a Once-Weekly Application of Corplex Donepezil Transdermal Delivery System (TDS) Compared to Daily Oral Administration of Aricept in Healthy Adult Subjects

Condition or disease Intervention/treatment Phase
Alzheimer Disease Drug: Donepezil TDS Version A Drug: Donepezil TDS Version B Drug: Aricept Drug: Donepezil TDS Version D Drug: Donepezil TDS Version E Phase 1

Detailed Description:

Part A:

60 male and female subjects will be enrolled Subjects will receive 2 versions of once-weekly Corplex Donepezil TDS and QD oral Aricept; each administered for 35 days in 3 different treatment periods.

For each treatment period; Subjects will receive a lead-in dose of approximately 5 mg donepezil/day for 7 days before commencing a dose of 10 mg donepezil/day for 28 days. Blood samples for donepezil PK and red blood cell (RBC) AChEI (as a potential pharmacodynamic [PD] marker) will be collected pre-dose through Week 8.

Adhesion and skin irritation will be monitored throughout TDS Treatments. A washout period of at least 21 days between the last study drug administration (oral administration or removal of TDS, as appropriate) in each treatment period and the first application of TDS or oral drug administration, as appropriate, in the following treatment period.

Safety will be monitored throughout the study by adverse event reporting, repeated clinical and laboratory evaluations

Part B:

Up to 47 subjects male and/or female will be enrolled This is an open-label, randomized, 2-way crossover sub-study. Eligible subjects will be randomized to 1 of 2 treatment sequences prior to the first TDS application.

Subjects will receive 2 different once-weekly Corplex Donepezil TDS treatments (Treatments D and E), each administered for 1 week, in 2 different treatment periods (Treatment Period 1 and Treatment Period 2).

In each treatment period, subjects will receive a target dose of 5 mg donepezil/day for 7 days. There will be a washout period of 35 days between removal of the first TDS in Treatment Period 1 and application of the second TDS in Treatment Period 2.

Blood samples for donepezil PK will be collected pre-dose and through to Week 6 of each treatment period.

Safety will be monitored throughout the sub-study by repeated clinical, skin irritation and laboratory evaluations.

Primary Outcome Measures :
  1. Steady-state PK [ Time Frame: TDS PK sampling time-points: Predose; Day 1 (hr0); Post-dose; Day 1 (hr2,6,12); Day 2-15,22 (hr0); Day 29 (hr0,3,6,12); Day 30-35 (hr0,12) Day 36 (hr0, 2,6,12); Day 37-38,41,44,47,50,54 (hr0); ]

    To evaluate the steady-state PK of donepezil following once weekly Corplex Donepezil TDS application compared to once-daily (QD) oral administration of Aricept.

    Aricept PK sampling time points; Day 1 (hr0,1,2,3,4,6,8,12); Day 2,8,15,22,29 (hr0); Day 35(hr0,1,2,3,4,6,8,12); Day 36-37,40,43,46,49,53 (hr0)


  2. PK (Part B) [ Time Frame: TDS PK sampling time-points: Predose; Day 1 (hr0); Post-dose; Day 1 (hr2,6,12); Day 2-8 (hr0,12); Day 9,10,11,13,16,19,22,26,30,36 (hr0) ]
    To compare the PK of 2 once-weekly Corplex Donepezil TDS treatments (target dose 5 mg donepezil/day)


Secondary Outcome Measures :
  1. Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 (Part A and B) [ Time Frame: Daily during 36-day confinement period and 7 visits over the 21 day wash-out period. ]
    General Safety (AE and SAE as reported by subject following guidance CTCAE v4.0)

  2. PI assessment of local skin irritation response to TDS (Part A and B) [ Time Frame: Part A: Daily during 36-day confinement period and 7 visits over the 21 day wash-out period. Part B:Daily during 10-day confinement period and 8 visits over the 28-35 day wash-out period. ]
    To evaluate the safety and tolerability (including local skin irritation) of once-weekly Corplex Donepezil TDS. Skin irritation assessed using 8 pt categorical scale based on former FDA.gov/ohrms/dockets/98fr/990236GD.pdf. The Skin Irritation scale is: no irritation; minimal erythema/barely perceptible; definite erythema readily visible, minimal edema or minimal papular response; erythema and papules; definite edema; erythema, edema and papules; vesicular eruption; strong reaction spreading beyond application site.

  3. PI assessment of TDS Adhesion per FDA UCM504157 [ Time Frame: Twice daily during 36-day confinement period ]
    To evaluate the adhesion of once-weekly Corplex Donepezil TDS. Adhesion is based on the adhered area (%) of the patch according to FDA.gov/downloads/Drugs/GuidanceComplianceRegulatory Information/Guidances/UCM504157.pdf. Specifically: ≥ 90% adhered (essentially no lift off skin); ≥ 75% to <90% adhered (some edges only lifting off skin); ≥ 50% to <75% adhered (less than half the TDS lifting off skin); < 50% adhered but did not detach (not detached, but more than half of the TDS lifting off skin without falling off); patch completely detached (TDS detached, completely off skin).
