Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an adaptive open-label, first-in-human (Phase IIa) study designed to assess the safety (and efficacy) of Aurase Wound Gel, an enzymatic debridement product, intended for topical application to sloughy venous leg ulcers (VLU)

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The study has been designed as a dose escalation study, and will serially explore increasing concentrations of the Aurase enzyme in a relevant patient population. Five cohorts (of 10 patients each, except cohort 1 with 5 patients), will receive standard of care supplemented with increasing concentrations of Aurase and will be assessed for clinical tolerability at the wound site, systemic safety and efficacy (extent of wound debridement) over a period of 4 weeks. Patients will receive a total of 12 doses of Aurase Wound Gel. At the end of the study, patients will revert to standard of care only.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Aurase wound gel X0

Cohort 1: Aurase wound gel x0 dose concentration

Group Type EXPERIMENTAL

Aurase Wound gel

Intervention Type DRUG

Aurase Wound Gel is reconstituted from Aurase Component A (a hydrogel) and Aurase Component B (stabilised solutions of Aurase enzyme). By diluting different strengths of Aurase Component B with Component A, specific concentrations of Aurase Wound Gels with differing Aurase contents are yielded.

Aurase wound gel X1

Cohort 2: Aurase wound gel x1 dose concentration

Group Type EXPERIMENTAL

Aurase Wound gel

Intervention Type DRUG

Aurase Wound Gel is reconstituted from Aurase Component A (a hydrogel) and Aurase Component B (stabilised solutions of Aurase enzyme). By diluting different strengths of Aurase Component B with Component A, specific concentrations of Aurase Wound Gels with differing Aurase contents are yielded.

Aurase wound gel X1.8

Cohort 3: Aurase wound gel X1.8 dose concentration

Group Type EXPERIMENTAL

Aurase Wound gel

Intervention Type DRUG

Aurase Wound Gel is reconstituted from Aurase Component A (a hydrogel) and Aurase Component B (stabilised solutions of Aurase enzyme). By diluting different strengths of Aurase Component B with Component A, specific concentrations of Aurase Wound Gels with differing Aurase contents are yielded.

Aurase wound gel X5

Cohort 4: Aurase wound gel X5 dose concentration

Group Type EXPERIMENTAL

Aurase Wound gel

Intervention Type DRUG

Aurase Wound Gel is reconstituted from Aurase Component A (a hydrogel) and Aurase Component B (stabilised solutions of Aurase enzyme). By diluting different strengths of Aurase Component B with Component A, specific concentrations of Aurase Wound Gels with differing Aurase contents are yielded.

Aurase wound gel X9

Cohort 5: Aurase wound gel X9 dose concentration

Group Type EXPERIMENTAL

Aurase Wound gel

Intervention Type DRUG

Aurase Wound Gel is reconstituted from Aurase Component A (a hydrogel) and Aurase Component B (stabilised solutions of Aurase enzyme). By diluting different strengths of Aurase Component B with Component A, specific concentrations of Aurase Wound Gels with differing Aurase contents are yielded.
