NexoBrid® Clinical Efficacy
The safety and efficacy of NexoBrid were evaluated in three clinical studies.1
93% of adults treated with NexoBrid achieved ≥95% eschar removal vs 4% with gel vehicle1
NexoBrid achieved ≥95% eschar removal 2.8 days sooner than SOC* in adults1
Median Time to ≥95% Eschar Removal
Only 4% of adults treated with NexoBrid required follow up excision vs 72% with SOC1*
Incidence of Excision for Eschar Removal
NexoBrid achieved ≥95% wound closure in 31 days vs 36 days with SOC1*||¶
Median Time to ≥95% Wound Closure
(Safety Endpoint)
*Standard of care (SOC) included a combination of surgical and non-surgical eschar removal procedures such as: tangential, minor, avulsion, Versajet, and/or dermabrasion excision per the investigators’ discretion.
†The statistical test that resulted in this p-value was Fisher’s Exact Test.
‡The statistical test that resulted in this p-value was Wilcoxon-Gehan Test.
§The statistical test that resulted in this p-value was Wald Chi-Square.
||Study 1 used Kaplan-Meier methods to estimate median time to ≥95% wound closure for all target wounds (TWs) on a subject. This was a noninferiority endpoint.
¶Subjects were not evaluated frequently enough after achieving ≥95% wound closure to adequately assess time to 100% wound closure.
Review Study 2:
NexoBrid compared to SOC in adult patients1
Review Study 3:
NexoBrid compared to SOC in Pediatric Patients1
Only 15% of DPT wounds in adults treated with NexoBrid required follow up excision vs 63% with SOC1*
Incidence of Excision for Eschar Removal Performed on DPT Wounds
NexoBrid resulted in a significant reduction of DPT wound autografts vs SOC (18% with NexoBrid vs 34% with SOC)2*
The mean percent of DPT wound area autografted was significantly lower with NexoBrid vs SOC (8.4 ± 21.3 with NexoBrid vs 21.5 ± 34.8 with SOC)2*
NexoBrid achieved ≥95% wound closure in 33 days vs 24 days with SOC2*‡§
Median Time to ≥95% Wound Closure (Per Subject)
*Standard of care (SOC) included a combination of surgical and non-surgical eschar removal procedures such as: tangential, minor, avulsion, Versajet, and/or dermabrasion excision per the investigators’ discretion.
†The statistical test that resulted in this p-value was Logistic Regression Model.
‡Study 2 used Kaplan-Meier methods to estimate median time to ≥95% wound closure in randomized subjects.
§Subjects were not evaluated frequently enough after achieving ≥95% wound closure to adequately assess time to 100% wound closure.
||The statistical test which resulted in this p-value was the log rank test.
¶The statistical test that resulted in this p-value was the Analysis of Covariance (ANCOVA) Model.
Review Study 1:
NexoBrid Compared to SOC and gel vehicle in adult patients
Review Study 3:
NexoBrid compared to SOC in Pediatric Patients1
NexoBrid achieved ≥95% eschar removal 5 days sooner than SOC in pediatric patients.1*
Median Time to ≥95% Eschar Removal in Pediatrics
Only 8% of pediatric patients treated with NexoBrid® required follow up excision vs 64% with SOC1‡
Incidence of Excision for Exchage Removal in Pediatrics
NexoBrid achieved ≥95% wound closure in 32 days vs 34 days with SOC1†||
Median Time to ≥95% Wound Closure in Pediatrics
Safety Endpoint
*Eschar removal was considered ≥95% total debridement per treated wound.
†The statistical test that resulted in this p-value was Wilcoxon-Gehan Test.
‡Standard of care (SOC) included a combination of surgical and non-surgical eschar removal procedures such as: tangential, minor, avulsion, Versajet, and/or dermabrasion excision per the investigators’ discretion.
§The statistical test that resulted in this p-value was Logistic Regression Model using a re-randomization test.
||The estimated median time to reach 100% wound closure on a target wound level was 44 days for the NexoBrid arm and 43 days for the SOC arm.
¶Study 3 used Kaplan-Meier methods to estimate median time to ≥95% wound closure in randomized subjects.
