Brief Summary

To evaluate the saftye and effectiveness of AIV001 treatment on scar formation and/or keloid scar recurrence following keloidectomy.

Detailed Description

AIV001 (axitinib) has been formulated to provide focal disease-modifying therapy for patients undergoing surgical procedures where scar formation will occur. This was a multicenter, dose-escalation open label study to assess the safety and efficacy of AIV001 on scar formation and/or keloid recurrence following keloidectomy. This study design is an evaluation of surgical excision of keloid scar tissue followed by AIV001 intradermal injection. On Day 1, following keloidectomy, the incision area (devoid of keloid scar tissue) was sutured, creating an incision line. The incision line is the area of scar formation and assessment. This is a variable dose study defined by incision line length. The incision line length measurement defined each subject's AIV001 treatment based on the dose plan table in the protocol. Subjects received a minimum of 1 and up to 3 treatments, dependent on the protocol amendment implemented at the time of their participation and PI discretion based upon safety assessments. The excised tissue was sent to pathology for confirmation of keloid scar tissue. The treatment interval was Day 1 to Day 30 visits with observation visits on Days 60, 90, 183, and 365. A safety data review was conducted after the first 3 subjects in Cohort 1 completed the Day 30 visit. Assessment of local skin reactions (LSRs), wound healing, vitals, treatment-emergent adverse events (TEAEs) and pre-defined dose-limiting toxicities (DLTs) were reviewed to determine whether additional subjects were permitted to be enrolled. If safety was deemed acceptable, enrollment into Cohort 1 continued and Cohort 2 was open for enrollment. The same safety data review was conducted at Day 30 visit for the first 3 subjects enrolled in Cohort 2. The open-label study design allowed for adjustments to the dosing regimen (timing and frequency of dosing) based on review of each consecutive dosing cohort.
