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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 60 years (Adult)

Accepts Healthy Volunteers

No

Inclusion Criteria:

  • Male of female, aged 18 to 60, inclusive
  • No clinically relevant abnormalities identified by a detailed medical history and vital signs
  • Presence of one keloid scar, up to 2.2 cm length and up to 1.2 cm width, at least 1 year from formation, and located on trunk or arms
  • Willing to undergo surgical excision of keloid
  • No concurrent treatment of the study keloid or prior treatment within last 2 months

Exclusion Criteria:

  • Prior keloidectomy of study keloid
  • History of genetic disorder that predisposes to keloids (e.g., Ehlers-Danlos syndrome, Ullrich congenital muscular dystrophy, etc.)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Adverse events
Time Frame: Approximately 365 days
Incidence of adverse events
Approximately 365 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Keloid recurrence
Time Frame: 365 days
Number of subjects experiencing keloid recurrence within study duration
365 days
Modified Vancouver Scar Scale (mVSS)
Time Frame: Day 90 and Day 180
Modified Vancouver Scar Scale (mVSS) includes four categories of scar quality (i.e., pliability (0-4), height (0-4), vascularity (0-3), and pigmentation (0-3)), with 0 representing normal body skin. The composite mVSS scar score (ranges 0-14) is the sum of the 4 category scores to represent the overall scar quality.
