Study summary

A study to assess the skin irritation and sensitization potential of Corplex™ Donepezil Transdermal Delivery System (TDS)

Read the detailed description

This study is a multiple center, randomized, double-blind, vehicle-controlled, and multiple-dose study to assess skin irritation and skin sensitization in healthy subjects.

Subjects will be randomized prior to the first TDS application. The total duration of the study from Screening to Follow-up is approximately 95 days for subjects participating in the Induction Phase and the Challenge Phase of the study and potentially up to 156 days for subjects requiring to complete Re-Challenge Phase.

Skin irritation will be monitored by visual scoring scales. TDS adhesion will be assessed during TDS wear period. Safety will be monitored throughout the study by clinical and laboratory evaluations.

Inclusion criteria

  • Healthy, adult, male or female
  • ≥ 18.0 and ≤ 35.0 kg/m2
  • Medically healthy, as deemed by the Investigator
  • Have a skin type with Fitzpatrick scale score of I, II, or III

Exclusion criteria

Exclusion Criteria:

  • History or presence of alcoholism or drug abuse
  • History or presence of or idiosyncratic reaction to the study product or related compounds
  • Positive urine drug or alcohol results
  • Female subjects with a positive pregnancy test or who are lactating
  • Any of the following drugs, but not limited to, for 30 days prior to the first dose of study product treatment on Day 1 and throughout the study:

    1. Inducers of cytochrome enzymes and/or P-glycoprotein
    2. Anti-inflammatory drugs or cyclooxygenase 2 analgesics
    3. Beta-blockers
    4. Cholinergics and anticholinergics
    5. Muscle relaxants, anti-Parkinsonian, or neuroleptic medications
  • History or presence of significant skin damage deemed by the investigator to potentially interfere
  • Any medical or surgical procedure or trauma
  • Participation in another clinical study within 30 days or 5 times the half-life of the product (whichever is longer) prior to the first study product treatment
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

  • Placebo comparator
    Vehicle TDS

    Subjects will receive Vehicle TDS during Induction, Challenge, and Re-Challenge phase.

    Drug: Vehicle TDS

What researchers measure

Primary outcomes

  1. Mean Cumulative Skin Irritation Score of Donepezil Corplex TDS (Induction Phase)

    Mean Cumulative skin irritation score is determined by averaging the combined Dermal Response score (8-point categorical scale using numeric values) and the Other Effects score (6-point categorical scale using alphabet letters equivalent to numeric values) during the induction phase of the study.

    Time frame: Induction (21 days)

  2. Number of Subjects with Skin sensitization potential of Corplex TDS (Challenge Phase)

    Subject's sensitization potential will be assessed using the combined Dermal Response score (8-point categorical scale using numeric values) and the Other Effects score (6-point categorical scale using alphabet letters equivalent to numeric values) . The last of 48 hr or 72 hr score collected after TDS removal during the Challenge Phase will be assessed. Provided the combined score is 2 or greater, it will then be compared to the skin irritation scores collected during the induction phase. If the last Challenge Phase score is 2 or greater and generally exceeds the skin irritation scores collected during the induction phase, the subject will return for the Re-Challenge phase.

    Time frame: Challenge: Up to 5 days including 2-day TDS application and a 3-day visual scoring of the TDS application site following TDS removal

  3. Number of Subjects with Skin sensitization potential of Corplex TDS (Re-Challenge Phase)

    Subject's sensitization potential will be assessed using the combined Dermal Response score (8-point categorical scale using numeric values) and the Other Effects score (6-point categorical scale using alphabet letters equivalent to numeric values). The last of 48 hr or 72 hr score collected after TDS removal during the Re-Challenge phase will be assessed. The subject will be considered for potential sensitization if they meet the same criteria in both Challenge phase and Re-Challenge phase (i.e. a combined score of 2 or greater at the last assessment at 48 hr or 72 hr post patch removal and the score are generally higher compared to induction phase scores.

    Time frame: Re-Challenge: Up to 5 days including 2-day TDS application and a 3-day visual scoring of the TDS application site following TDS removal

Secondary outcomes

  1. Mean Cumulative Skin Irritation Score of Donepezil Corplex TDS compared to Vehicle TDS (Induction Phase)

    Mean cumulative skin irritation will be determined and compared between Corplex Donepezil TDS and Vehicle TDS. Mean Cumulative skin irritation score is determined by averaging the combined Dermal Response score (8-point categorical scale using numeric values) and the Other Effects score (6-point categorical scale using alphabet letters equivalent to numeric values) during the induction phase of the study.

    Time frame: Induction (21 days)

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 14, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
