Objective:
This analysis includes pooled safety data from 2 clinical trials (NCT01437852; NCT03005106) that evaluated the safety and efficacy of StrataGraft in patients with deep partial-thickness (DPT) burns.
Methods:
The study enrolled 101 adult patients with thermal burns covering 3-49% of total body surface area. Patients were followed for up to 1 year. The pooled safety events included: adverse events (AEs), adverse reactions (ARs), serious AEs (SAEs), discontinuation, and deaths; immunological responses (reactivity to panel reactive antibodies [PRA] and human leukocyte antigen [HLA] class 1 alleles); and persistence of allogeneic DNA from StrataGraft.
Results:
Eighty-seven (86.1%) patients experienced 397 AEs. Thirty patients (29.7%) experienced ARs; 16 patients (15.8%) experienced SAEs. The most frequent AEs were pruritus (n = 31; 30.7%), and blister, hypertension, and hypertrophic scar (n = 11 each; 10.9%); the most common AR was pruritus (n = 13; 12.9%). One patient discontinued the study; 2 patients experienced SAEs (unrelated to StrataGraft) leading to death. PRA and HLA allele reactivity was ≤ 25% at Month 3, with no persistent allogeneic DNA from StrataGraft.
Conclusions:
StrataGraft was well tolerated by patients, with a safety profile similar to autograft. StrataGraft may offer a safe alternative to autograft for DPT burns.
