Registered outcomes5

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryNumber of Subjects Reported at Least One Adverse Event, Safety Populationbaseline 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.
PrimaryNumber of Adverse Events Reported, Safety Populationbaseline 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.
PrimaryComplete Wound Closure Responder, ITT Populationfrom baseline at Weeks 8, 10, and 12One wound is a responder if the reduction from baseline in wound surface is ≥90%.
PrimaryTime to Wound Closure Analysis, ITT Populationbaseline to complete wound closureTime to wound closure was defined as the time from the first treatment to Complete Wound Closure (≥90% reduction in wound surface area from baseline)

The per-protocol (PP) population: all subjects in the ITT population who have had at least one paired assessment of the target wound area post-administration and completed the protocol as planned.
