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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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
Multi-centre, open-label study to evaluate the potential for systemic bioavailability of single and/or multiple doses of RECCE®327 topical gel into the systemic circulation when applied to acute bacterial skin and skin structure infections (ABSSSI).

The study will also evaluate the safety and tolerability, plasma pharmacokinetics, and efficacy of RECCE®327 topical gel when applied to ABSSSI, after a single dose and multiple doses.

The study will consist of sequential enrolment of up to approximately 30 participants who present with an ABSSSI, and who meet all inclusion criteria and do not meet any exclusion criteria. Participants may be treated in either the outpatient or inpatient setting.

RECCE®327 topical gel will be applied once daily for seven (7) days to the participant's ABSSSI, followed by safety and efficacy evaluations, then a possible additional seven (7) day treatment period, (at investigator recommendation), with repeat safety and efficacy evaluations at the end of the treatment period.

RECCE327 topical gel 4g single use tube. The dose amount will be calculated as follows: weight of tube before application – weight of tube after application = dose amount (g) of RECCE®327 topical gel.
