TWB-103 for Adult Patients With Split-Thickness Skin Graft Donor Site Wounds

Donor Site Complication Clinical Trial

Official title: A Phase I/II Study to Evaluate the Safety and Efficacy of TWB-103 in Adult Patients With Split-Thickness Skin Graft Donor Site Wounds (DSW)

Status Completed

Clinical Trial Summary

Primary objective: 1. To evaluate the safety of TWB-103 in split-thickness skin graft donor site wounds (DSW) for Phase I in terms of Incidence of treatment-related AEs and SAEs (including infections and bleeding) 2. To evaluate the efficacy for Phase I+II of TWB-103 in split-thickness skin graft donor site wounds (DSW) in terms of The healing time from DSW creation to 100% re-epithelialization Secondary objective: 1. To evaluate the efficacy of TWB-103 in split-thickness skin graft donor site wounds (DSW) in secondary efficacy endpoints 2. To evaluate the safety of TWB-103 in split-thickness skin graft donor site wounds (DSW) in secondary safety endpoints

Clinical Trial Description

The study was designed to evaluate the safety and efficacy of the TWB-103 in adult subjects with split-thickness skin graft donor site wounds (DSW). In Phase I proportion, eligible subjects were recruited sequentially with one week staggering of treatment. Eligible subjects were randomized into TWB-103 or Placebo groups in a 1:1 ratio. Phase I was planned to recruit 3 evaluable subjects each in TWB-103 and Placebo groups. Evaluable subjects in Phase I were (1) he/she who received at least one dose and had follow-up evaluation at least 14 days after the first dose or (2) he/she who received at least one dose and had early withdrawn due to safety reasons before Day 28. When all of those 6 evaluable subjects completed the planned treatment period (14 days or till first 100% re-epithelialization, which came first), the recruitment was temporarily stopped for 14 days for safety observation. The safety data before and on Day 28 Visit were reviewed by the sponsor and the principal investigator. If no safety issue was decided, the study would enter Phase II portion and eligible subjects would be randomized into a 1:1 ratio into one of the TWB-103 and Placebo groups. The dosing regimen designed in Phase II portion was the same as it was designed in Phase I portion. Subjects were instructed to attend scheduled visits at Screening, Day 0 (treatment start the day), Day 3, Day 7, Day 10, and Day 14 (end of treatment). All subjects were scheduled to attend a follow-up visit on Day 28 to evaluate the status of the target wound and then enter a 360-day follow-up phase. During the 360-day follow-up, four follow-up visits were scheduled at 90±14 days, 180±14 days, 270±14 days, and 360±14 days following the subject's Day 28 visit (if no Day 42 visit) or Day 42 visit. ;
