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.
Intervention code [1] 328871 0
Treatment: Drugs
Comparator / control treatment
No control group.
The study analyses will look at participants response to a single dose of recce (Day 1) assessments and multiple doses (after 7 days of daily treatment), and for participants who have extended treatment (after 14 days of treatment)
Control group
Uncontrolled

Outcomes
Primary outcome [1] 338605 0
To evaluate the potential for systemic bioavailability of single and multiple doses of RECCE®327 topical gel applied once daily for 7 or 14 days to infected ABSSSI via analysis of plasma concentrations of RECCE®327

Eligibility
Key inclusion criteria
- Must be able to read and understand study information sheet and must give voluntary written informed consent prior any study assessment
- Aged 18 years or older at screening, with suitability confirmed by screening assessments.
- Female participants must: a) Be of non-child-bearing potential or surgically sterilised (hysterectomy, bilateral salpingectomy, bilateral oophorectomy at least 6 weeks before the Screening Visit) or postmenopausal (where postmenopausal is defined as no menses for 12 months without an alternative medical cause), or b) All female participants (unless the Investigator assesses them to not be of childbearing potential), must have a negative urine pregnancy test before the first RECCE®327 administration (Day 1). They must agree not to attempt to become pregnant, must not donate ova for a minimum of 30 days after last RECCE®327 administration, and must agree to: Use at least one form of highly effective contraceptive method between signing consent, during the study, and at least 30 days after the last dose of study therapy.
- Male participants must agree to abstain from unprotected sex and sperm donation after signing the consent through 90 days after the last dose of study medication.
