Trial Outcomes & Findings for MT2015-20: Biochemical Correction of Severe EB by Allo HSCT and Serial Donor MSCs (NCT NCT02582775)
NCT ID: NCT02582775
Last Updated: 2024-09-19
Results Overview
An event defined as death or a 50% increase in a patient's IScoreEB from baseline
COMPLETED
PHASE2
17 participants
1 year post-transplant
2024-09-19
Participant Flow
The JEB subject (n=1) was enrolled on Arm B, receiving the same therapy as the RDEB subjects, but pulled out and reported separately due to the very different baseline disease course.

Timeframe: 1 year post-transplantiscorEB surveys are a validated, standard of care tool used to assess disease status in patients with Epidermolysis Bullosa. Measure changes in quality of life (QOL) through pain, itching, and general QOL IScorEB questionnaire. Scores can range from 16 to 112. The QOLS scores are summed so that a higher score indicates higher quality of life.
