NCT05887804

Brief Summary

This study is a double-blind randomized controlled trial (RCT) examining the effect of intralesional injection of umbilical cord-derived mesenchymal stem cells (UC-MSC), umbilical cord-derived conditioned medium (UC-CM), or triamcinolone acetonide (TA) on keloids carried out using CONSORT statement. Research is directed at studying keloid volume reduction and changes in POSAS score.

Outcome Measures

Primary Outcomes (2)

  • Keloid volume reduction

    Volume was measured by CT-scan 2 weeks and 17 weeks after the first visit

    15 weeks

  • The Patient and Observer Scar Assessment Scale (POSAS) score reduction

    Symptoms were measured using The Patient and Observer Scar Assessment Scale (POSAS) on the first visit, five weeks, 13 weeks, and 17 weeks after the first visit. Each item of the POSAS is rated on a 10-point score. The lowest score is '1', corresponding to the normal skin situation (i.e., normal pigmentation, no itching). Score 10 equals the most significant difference from normal skin (i.e., the worst imaginable scar or sensation). The symptoms are considered improved if the score gets lower. The total score of both scales can be calculated by summing up the scores of each of the six items. The total score can range from 6 to 60.

Study Arms (3)

umbilical cord-derived mesenchymal stem cells (UC-MSC)

EXPERIMENTAL

UC-MSC was collected in 50 mL of transport medium, which contained alpha minimal essential medium (αMEM \[GIBCO 12000-0221\]), penicillin/streptomycin (final concentration 300u/mL \[GIBCO 15140-122\]) and amphotericin B (final concentration 7500ng /mL \[JR Scientific 50701\]), and processed in less than 8 hours after collection. Group 1 was given UC-MSC 2 million cells/mL/cm3

Biological: umbilical cord-derived mesenchymal stem cells (UC-MSC)

umbilical cord-derived mesenchymal stem cells conditioned medium (UC-CM)

EXPERIMENTAL

group 2 was given UC-CM 1 mL/cm3

Biological: umbilical cord-derived mesenchymal stem cells conditioned medium (UC-CM)

triamcinolone acetonide

ACTIVE COMPARATOR

group 3 was given TA 40 mg/mL/cm3

Drug: Triamcinolone Acetonide (TA)

Interventions

Group 1 was injected UC-MSC 2 million cells/mL/cm3, given the same injection volume (1 mL) in every cm3 keloid volume using a 1 mL syringe and 27G needle. The injections were ultrasound-guided into the center of the lesion with a 30-45-degree angle using an in-plane technique, therefore the same pressure.

Model Details: Patients were screened initially by measuring the length and thickness of the keloids using a ruler. Patients who met the study inclusion criteria were randomly divided into 3 groups. Each patient in the groups was given the same injection volume (1 mL) in every cm3 keloid volume using a 1 mL syringe and 27G needle. The injections were ultrasound-guided into the center of the lesion with a 30-45-degree angle using an in-plane technique, therefore the same pressure. Group 1 was given UC-MSC 2 million cells/mL/cm3, group 2 was given UC-CM 1 mL/cm3, and group 3 was given TA 40 mg/mL/cm3.
