2026년 7월 12일 업데이트: Amin Tamadon, West Kazakhstan Marat Ospanov Medical University
A Phase 1 Split-Site Pilot Study to Evaluate the Safety and Dermal Tolerability of Topical Exosome-Containing Liquid in Healthy Adult Volunteers
This Phase 1 split-site pilot study will evaluate the safety and dermal tolerability of a topical exosome-containing liquid in 10 healthy adult volunteers.
The investigational liquid will be applied to a small defined area of intact skin.
A vehicle liquid without exosomes may be applied to a matched contralateral skin site as a control.
The study will assess local skin reactions, systemic adverse events, vital signs, clinical laboratory parameters, and feasibility of topical administration.
No burn wound or artificial skin wound will be induced in participants in this Phase 1 safety study.

상세 설명
The investigational product is a sterile topical exosome-containing liquid being developed for future evaluation in burn wound repair. Preclinical in vivo evaluation in murine wound models suggested improved wound closure and better histological organization of repaired skin after topical exosome-containing formulation administration, with the therapeutic effect being more pronounced in the thermal burn model. In the burn model, the exosome-containing formulation group showed faster wound-area reduction, improved epidermal and dermal organization, reduced inflammatory cellularity, and no significant body-weight differences compared with control groups.
This first-in-human Phase 1 study is designed to evaluate safety and dermal tolerability in healthy adult volunteers before the product is tested in patients with burn wounds. No artificial burn wound or skin wound will be created. The investigational liquid will be applied to a small defined area of intact skin according to the protocol-defined dose and schedule. If a split-site design is used, vehicle liquid without exosomes will be applied to a matched contralateral intact skin site as a control. Participants will be monitored for local skin irritation, erythema, edema, pruritus, burning sensation, pain, rash, allergic reaction, systemic adverse events, vital signs, and clinical laboratory abnormalities.
The first two participants will be enrolled as sentinel participants. Safety data through at least 72 hours after first application will be reviewed before enrollment of the remaining participants. The main purpose of the study is to determine whether topical administration of the exosome-containing liquid is safe and tolerable on intact human skin.

실험적: Exosome-Containing Liquid and Vehicle-Control Skin Sites
Healthy adult volunteers will receive topical exosome-containing liquid applied to a small defined area of intact skin.
In the split-site design, vehicle liquid without exosomes will be applied to a matched contralateral intact skin site as a control.
No burn wound or artificial skin wound will be induced.
|
The investigational product is a sterile topical liquid containing exosome-enriched extracellular vesicles derived from [insert cell source, e.g., mesenchymal stromal cells].
The liquid will be applied topically to a small defined area of intact skin at a dose of [insert exact dose, e.g., X mL/cm² containing Y particles/mL, equivalent to Z particles/cm²] according to the protocol-defined schedule.
The product is investigational and is being evaluated for safety and dermal tolerability before future testing in patients with burn wounds.
다른 이름들:
Vehicle liquid without exosomes will be applied topically to a matched contralateral intact skin site according to the same protocol-defined schedule as the exosome-containing liquid.
The vehicle liquid is used as a within-participant control for local dermal tolerability assessment.

Maximum Total Score on the Draize Dermal Irritation Scale at the Exosome-Containing Liquid Application Site
기간: Baseline, 30 minutes, 24 hours, 48 hours, 72 hours, Day 7, Day 14, and Day 28
|
The Draize Dermal Irritation Scale grades erythema and eschar formation from 0, indicating no erythema, to 4, indicating severe erythema or eschar formation, and edema from 0, indicating no edema, to 4, indicating severe edema.
The total score is the sum of the erythema/eschar score and edema score and ranges from 0 to 8. Higher scores indicate worse local skin irritation.
The maximum total score observed at the exosome-containing liquid application site will be reported.

Baseline, 30 minutes, 24 hours, 48 hours, 72 hours, Day 7, Day 14, and Day 28

Within-Participant Difference in Total Draize Dermal Irritation Scale Score Between Exosome-Containing Liquid and Vehicle-Control Sites
기간: Baseline, 30 minutes, 24 hours, 48 hours, 72 hours, Day 7, Day 14, and Day 28
|
The within-participant difference will be calculated as the total Draize Dermal Irritation Scale score at the exosome-containing liquid application site minus the total score at the vehicle-control liquid application site at each assessment time point.
The total Draize score ranges from 0 to 8, with higher scores indicating worse local skin irritation.
Positive values indicate higher irritation at the exosome-containing liquid site, and negative values indicate higher irritation at the vehicle-control site.

Percentage of Planned Topical Applications Completed According to Protocol
기간: From Day 0 through Day 14
|
For each participant, the topical application completion percentage will be calculated as the number of completed topical applications divided by the number of protocol-planned topical applications, multiplied by 100.
The outcome will be reported as the mean percentage of planned topical applications completed across participants.
A higher percentage indicates better feasibility of topical application.

IPD 계획 설명
No. Individual participant data will not be shared because this is a small Phase 1 first-in-human safety and dermal tolerability study in 10 healthy volunteers, and de-identified individual-level data may still carry a risk of participant re-identification.
Aggregate study results, adverse event summaries, and protocol-defined outcome summaries may be reported in ClinicalTrials.gov
