SkinTE® Met Primary and Secondary Endpoints in Multicenter, Randomized Controlled Trial in Venous Leg Ulcers

SALT LAKE CITY, Feb. 22, 2022 /PRNewswire/ -- PolarityTE, Inc. (Nasdaq: PTE) today announced results from a multi-center randomized controlled trial evaluating treatment of Venous Leg Ulcers (VLU) with its investigational product SkinTE® plus standard of care (SOC) vs SOC alone (NCT03881267).  The trial met the primary endpoint of wound closure at 12 weeks and secondary endpoint of Percent Area Reduction (PAR) at 4, 6, 8, 10, and 12 weeks.  29 participants were evaluated across 10 sites with 14 participants receiving SkinTE plus SOC and 15 receiving SOC alone.  PolarityTE is pleased to announce today the final analysis of the full data set, which includes:

• Primary Endpoint: 71% (10/14) of participants receiving SkinTE plus SOC had wound closure at 12 weeks versus 33% (5/15) of participants receiving SOC alone (p=0.046)
• Secondary Endpoint: Percent Area Reduction (PAR) assessed at 4, 6, 8, 10, and 12 weeks was significantly greater for the SkinTE plus SOC treatment group vs SOC alone (p=0.000035)
• 93% (13/14) of SkinTE plus SOC treated participants received a single application of SkinTE

Mean (SD) values for PAR at weeks 4, 6, 8, 10, and 12 by treatment group

• Average wound size for the SkinTE plus SOC treatment group was 5.8 cm² versus 6.3 cm² for the SOC treatment group (p=0.46).  A comparison by treatment group for wound-related variables showed that variables (e.g., age, BMI, gender, race/ethnicity, alcohol use, smoking, diabetes, and creatinine) were well balanced between groups.  The number of debridements was significantly lower for the SkinTE plus SOC treatment group compared to the SOC group.
• There were 39 AEs allocated to 12 subjects. The SkinTE plus SOC treatment group had 17 AEs allocated to 5 subjects while the SOC group had 22 AEs allocated to 7 subjects.  There were 8 SAEs, 4 in the SkinTE plus SOC treatment group (1 subject) and 4 in the SOC group (2 subjects).

PolarityTE started this multicenter, randomized controlled trial with a target enrollment of 100 patients, but decided in the first quarter of 2021 to suspend the trial after 29 patients were enrolled because the Company believed that its resources would be better used in future clinical trials conducted under an open investigational new drug application (IND) that can be used in its eventual planned BLA submission.  Since that time, PolarityTE has received U.S. Food and Drug Administration (FDA) approval of its IND for the proposed indication of chronic cutaneous ulcers.  PolarityTE plans to conduct its first pivotal study under the IND in diabetic foot ulcers (DFU) and is evaluating additional wound types—including but not limited to VLUs—for its second planned pivotal study that is expected to be required for a BLA submission. 

PolarityTE's Chief Scientific Officer, Nikolai Sopko, MD, PhD, commented, "VLUs are the most common chronic lower extremity cutaneous ulcers of the leg, accounting for approximately 80% of leg ulcers.  It is estimated that 1% of the western population will suffer from a VLU in their lifetime, and the incidence and prevalence of VLUs continue to increase with an aging population.  We believe that these data strongly support the potential of SkinTE to deliver meaningful and positive outcomes for VLU patients and their healthcare providers who are seeking solutions to these highly prevalent and debilitating wounds." 

Richard Hague, Chief Executive Officer, commented, "We would like to thank all of the subjects who participated, the Study Chair, Dr. David Armstrong, all of the investigators and healthcare providers, and our clinical trial teams for their unwavering commitment and support during this trial.  As we prepare to commence our first pivotal study under our approved IND, we are incredibly pleased to share these results which support our belief that SkinTE has the potential to address the significant unmet needs related to VLUs, which are among the types of chronic cutaneous ulcers that we are seeking to address with our proposed indication for SkinTE."
