Study Endpoints

Primary Endpoints

To record safety outcomes of participants while on B-VEC.
Up to 112 weeks

Record reportable Adverse (AE) and Serious Adverse Events (SAEs) during the continued use of B-VEC to participants who have participated in and completed Krystal Biotech's Phase 3 Protocol (A Phase 3 Efficacy and Safety Study of Beremagene Geperpavec (B-VEC, previously KB103) for the Treatment of Dystrophic Epidermolysis Bullosa (DEB)), as an extension of use, upon study completion; as well as, for participants diagnosed with DEB who have not participated in the B-VEC Phase 3 trial.

Primary Wound With Complete Wound Healing (100% Wound Closure) on Weeks 22 and 24 or Weeks 24 and 26
26 weeks post-baseline

The primary wound was defined as a responder wound that met either of the following conditions: * Complete wound healing on Week 22 and Week 24, or * Complete wound healing on Week 24 and Week 26. For subjects with missing primary wound healing data, a multiple imputation approach (10 repliates) was used. The total numbers of primary wounds with complete healing for B-VEC and Placebo presented below were the average of those from the multiple imputation replicates, and therefore, they would not be whole numbers (integers).

Number of Subjects Reported at Least One Adverse Event, Safety Population
baseline to 12 weeks

Safety assessments included evaluation of medical and medication history, physical / skin examination, vital signs, adverse events, and laboratory evaluations. Due to the 'split-person' intrasubject design, the safety assessments were reported at subject level, but not per intervention.

Number of Adverse Events Reported, Safety Population
baseline to 12 weeks

Safety assessments included evaluation of medical and medication history, physical / skin examination, vital signs, adverse events, and laboratory evaluations. Due to the 'split-person' intrasubject design, the safety assessments were reported at subject level, but not per intervention.

Complete Wound Closure Responder, ITT Population
from baseline at Weeks 8, 10, and 12

One wound is a responder if the reduction from baseline in wound surface is ≥90%.

Time to Wound Closure Analysis, ITT Population
baseline to complete wound closure

Time to wound closure was defined as the time from the first treatment to Complete Wound Closure (≥90% reduction in wound surface area from baseline)

Duration of Wound Closure, ITT Population
Time from the complete closure to the first reopening of the same wound

Duration of wound closure

Secondary Endpoints

Primary Wound With Complete Wound Healing (100% Wound Closure) on Weeks 8 and 10 or Weeks 10 and 12
12 weeks post-baseline
Primary Wound Pain Severity (Visual Analog Scale (VAS)) Change for Ages 6 and Above Subjects at Weeks 22, 24, and 26.

Frequently asked questions about beremagene geperpavec

What is beremagene geperpavec used for?

Beremagene geperpavec is an investigational therapy for Dystrophic Epidermolysis Bullosa (DEB), a rare genetic skin disorder. It is being developed as a topical treatment for this condition. The drug is currently in Phase 3 clinical development and has not been approved by the FDA.

What does beremagene geperpavec target?

Beremagene geperpavec is a topical gene therapy that delivers a functional copy of the COL7A1 gene to skin cells. It is designed to restore production of type VII collagen, which is deficient in patients with Dystrophic Epidermolysis Bullosa. The drug is administered topically to wounds.

Who makes beremagene geperpavec?

Beremagene geperpavec is being developed by Krystal Biotech, Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol KRYS. The company is focused on developing gene therapies for rare diseases, with beremagene geperpavec being one of its lead product candidates.

What phase is beremagene geperpavec in?

Beremagene geperpavec is in Phase 3 clinical development for Dystrophic Epidermolysis Bullosa. It has completed three clinical trials, including two Phase 3 studies and one Phase 1/2 study. The drug is investigational and has not received FDA approval.

What clinical trials is beremagene geperpavec in?

Beremagene geperpavec has completed three clinical trials: NCT03536143, a Phase 1/2 study in 12 patients; NCT04491604, a Phase 3 efficacy and safety study in 31 patients; and NCT04917874, a Phase 3 long-term treatment study in 47 patients. All trials were conducted in the United States.
