Trial Outcomes & Findings for Study of Survival Duration for Donor Skin Cells in Skin Biopsy Wounds (NCT NCT01190865)

NCT ID: NCT01190865

Last Updated: 2017-07-02

Results Overview

The primary efficacy variable was detection of the full set of 17 Y STR loci. If all loci amplified such that a clear identification of a donor was possible, the test result was categorized as positive. If fewer loci amplified such that identification of the donor was not possible in a forensic setting, the result was categorized as negative. Descriptive statistics are presented for this variable.

Participant Flow

Subjects were enrolled at a single US investigational site, between September 14, 2010 and December 08, 2010.

Subjects underwent buccal smear to ensure absence of a Y chromosome or translocated material from a Y chromosome. Day 1, all subjects underwent a baseline 3mm skin punch biopsy on the inner upper arm followed by a single application of HP802-247.

PRIMARY outcome

Timeframe: Cohorts of 3 subjects were biopsied at weekly intervals for 8 weeks

Population: 3 subjects were withdrawn; 2 for non-compliance and one at the subject's request. One subject, who was available to replace a subject assigned to a weekly cohort if the subject was unavailable, was assayed on Day 57 with the subjects assigned to the Week 8 cohort.

The primary efficacy variable was detection of the full set of 17 Y STR loci. If all loci amplified such that a clear identification of a donor was possible, the test result was categorized as positive. If fewer loci amplified such that identification of the donor was not possible in a forensic setting, the result was categorized as negative. Descriptive statistics are presented for this variable.

SECONDARY outcome

Timeframe: Cohorts of 3 subjects were biopsied at weekly intervals for 8 weeks

Population: The analysis population consisted of the 8 cohorts of 3 subjects biopsied at weekly intervals over the 8-week duration of the study. It should be note that the cohort for Week 8 (Day 57) was composed of 4 subjects

The biopsy area was examined for the presence of the Y chromosome, based on the presence of a full set of Y-STR loci as well as partial sets, assayed by a commercial kit (AmpFISTRTM). Probit analysis was utilized to determine the time in days to 50% correct identification (ID50) of the implanted male DNA 17 loci in female volunteers, with regard to three DNA profile types, including partial DNA profile, \> 50% DNA profile, and full (or complete) DNA profile. The analysis was performed using SAS® PROC PROBIT
