Study Details
Study Description
Brief Summary
The primary purpose of this trial is to demonstrate the superiority of MC0518 compared to the first used best available therapy (BAT) with respect to overall response rate (ORR) in adult and adolescent participants with steroid-refractory acute graft-versus-host disease (SR-aGvHD) at Day 28.

|
| Active Comparator: Best Available Therapy (BAT) Participants will receive any one of the following systemic BATs based on the Investigator's decision: mycophenolate mofetil (MMF), extracorporeal photopheresis (ECP), anti-thymocyte globulin (ATG), everolimus, and ruxolitinib (RUX). |
Biological: BAT
BAT including MMF, ECP, ATG, everolimus, and RUX will be administered based on Investigator's decision.

Time to response is defined as the time from the date of the first treatment administration to the date of response.
- Duration of Response [Up to Month 24]
Duration is calculated from time from the first OR (CR or PR) until the time point of no aGvHD response in comparison to baseline.
- Best Overall Response (OR) [Up to Day 28]
Best OR is defined as the achievement of an OR at any time point up to and including Day 28. Number of participants with best OR will be reported.
- Cumulative Dose of Steroids for SR-aGvHD per Kilogram (kg) of Body Weight [Up to Day 60 and Month 24]
The cumulative dose of steroids given for SR-aGvHD per kg of body weight from baseline until Day 60 and until Visit Month 24 will be analyzed.

Number of participants with cGvHD will be reported.
- Time to Chronic Graft-versus-host Disease (cGvHD) [Day 60 to Month 24]

Number of participants with GF will be reported.
- Number of Participants with Relapse or Progression in Participants with Underlying Malignant Disease [Up to Month 24]
Number of participants with relapse or progression in participants with underlying malignant disease will be reported.
- Time to Relapse or Progression in Participants with Underlying Malignant Disease [Up to Month 24]
Time to relapse or progression in participants with underlying malignant disease will be reported.
- Event-free survival (EFS) [Up to Month 24]
EFS is defined as the time from the date of randomization to the date of the event. An event is defined as GF, relapse or progression of the underlying disease, or death due to any cause.
- Non-relapse Mortality (NRM) [Up to Month 24]
NRM is defined as the time from the date of randomisation to the date of the event. An event is defined as death without previous relapse or progression of the underlying disease.
- Number of Participants with Adverse Events (AEs) and Adverse Reactions (ARs) [Until Day 60 or until 30 days after last administration of trial treatment, whichever is later (Up to Month 24)]
- Number of Participants with Adverse Events (AEs) and Adverse Reactions (ARs) by Severity [Until Day 60 or until 30 days after last administration of trial treatment, whichever is later (Up to Month 24)]
Severity will be graded based on Common Terminology Criteria for Adverse Events (CTCAE) v5.0: Grade 1- Mild; Grade 2- Moderate; Grade 3- Severe; Grade 4- Life-threatening consequences; urgent intervention indicated; Grade 4- Death related to the AE.
- Change from Baseline in Performance score based on Karnofsky scale (recipient age >= 16 years) [Baseline, Days 8, 15, 22, 28, 60 and 100]
The Karnofsky performance score (KPS), which is reported on an ordinal scale from 0 to 100, provides a rough measure of the participant's well-being, including their ability to conduct activities of daily living and functional capacity. Higher score indicates normal, no complaints and no evidence of disease.
- Change from Baseline in Performance score based on Lansky Scale [Baseline, Days 8, 15, 22, 28, 60 and 100]
A Lansky score (recipient age greater than or equal to [>=] 1 years and less than [<] 16 years) will be recorded pre-treatment and measured serially at regular intervals after treatment. The score is a standard performance score that measures overall function of the child with a scale range from 0 to 100. Higher score indicates full activeness.
- Change from Baseline in EuroQol-5D-5L (EQ-5D-5L): Health Status Index (HSI) [Baseline, Days 28, 60, 100 and 180]
EQ-5D-5L is a 2-part instrument for use as a measure of health outcome, designed for self-completion by respondents. It consists of EQ-5D-5L descriptive system and EQ VAS. EQ-5D-5L descriptive system comprises of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each has 5 levels of perceived problems (1-no problem, 2-slight problems, 3-moderate problems, 4-severe problems, 5-extreme problems). Participant selects answer for each of 5 dimensions considering response that best matches his/her health "TODAY". Responses were used to generate a HSI. HSI ranges from 0 (dead) to 1.00 (full health).
- Change from Baseline in EuroQol-5D-5L (EQ-5D-5L): Visual Analogue Scale (VAS) [Baseline, Days 28, 60, 100 and 180]
EQ-5D-5L is a 2-part instrument for use as a measure of health outcome, designed for self-completion by respondents. It consists of EQ-5D-5L descriptive system and EQ VAS. The EQ VAS self-rating records the respondent's own assessment of his or her overall health status at the time of completion, on a scale of 0 (the worst health you can imagine) to 100 (the best health you can imagine).
- Change from Baseline in Functional Assessment of Cancer Therapy-Bone Marrow Transplantation (FACT-BMT) Score [Baseline, Days 28, 60, 100 and 180]
The FACT-BMT questionnaire was designed to measure the quality of life in subjects undergoing bone marrow (BM) transplantation. It consists of the following categories of assessment: physical well-being, social / family well-being, emotional well-being, functional well-being, and additional miscellaneous concerns that the subject may have concerning their healthcare, persons involved in their life, and other emotions and incapabilities. Score ranges from 0-164, with higher score indicating better quality of life.
