Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study involves administering RECCE327 topical gel to normal intact skin, once daily for seven (7) days on the ventral mid-section of the forearm (area will be 4 cm x 10 cm).

The daily dose amount will not exceed one tube of study medication (i.e., 4g of investigational product). The dose amount will be calculated as follows:
Weight of tube before application – weight of tube after application = dose amount (g) of study medication.

The safety and tolerability of the investigational product will be assessed throughout the study. Safety will be determined by physical examinations, vital signs, clinical laboratory parameters, adverse events, and skin tolerability assessments. Tolerability will be assessed with a two-part tolerability scale that incorporates dermal response and other effects of the medication on the skin.
