Plain-language summary
The purpose of this trial is the comparative evaluation of overall response rate (ORR) in paediatric participants with steroid-refractory acute graft-versus-host disease (SR-aGvHD) at Visit Day 28 after treatment with MC0518 or first used best available therapy (BAT).

Inclusion criteria
✓. Participant had a previous allogeneic HSCT as indicated for non-malignant (including inborn errors of metabolism, primary immunodeficiencies, haemoglobinopathies, and bone marrow failure syndromes) or hematological malignant disease or neuroblastoma.
✓. Participant has been clinically diagnosed with Grade II to IV aGvHD according to Harris et al. A biopsy of the involved organs with aGvHD is encouraged but not required.
✓. Participant has experienced failure of previous first-line aGvHD treatment (that is, SR-aGvHD), defined as:
✓. Male or female participant who is \>=28 days and \<18 years of age and has a minimum body weight of 3.2 kilograms (kg) at the Screening Visit.
✓. Participant has an estimated life expectancy of \>28 days.
✓. Participant, if female and of childbearing potential, agrees to use a highly effective contraceptive measure starting at the Screening Visit and continuing throughout the entire trial period.
✓. Participant, if a fertile male, agrees to sexual abstinence or to use a condom during sexual activity with their female partner of childbearing potential or pregnant partner. Additionally, if their partner is a woman of childbearing potential (WOCBP), then their partner must use an additional highly effective contraceptive method during sexual activity starting at the Screening Visit and continuing throughout the entire trial period.
✓. A written informed consent of the participant's parent(s) / legal guardian(s) (and participant's assent, when applicable) has been obtained according to national regulations.
. Participant has overt relapse or progression or persistence of the underlying disease.
✕. Participant has received the last HSCT for a solid tumor disease other than neuroblastoma.
✕. Participant has graft-versus-host disease overlap syndrome.
✕. Participant has received systemic first-line treatment for aGvHD other than steroids and a prophylaxis with other than calcineurin inhibitors, mammalian target of rapamycin (mTOR) inhibitors, anti-thymocyte globulin, mycophenolate mofetil, methotrexate, abatacept, or cyclophosphamide. Note: In vitro or in vivo graft manipulation to prevent graft-versus-host disease (example, T-cell depletion) during HSCT is permitted. Restart of initial prophylaxis with calcineurin inhibitors, mammalian target of rapamycin inhibitors, or mycophenolate mofetil after aGvHD onset is permitted.
✕. Participant has received prior mesenchymal stromal cell (MSC) treatment, including MC0518/Obnitix®.
✕. Participant has a known pregnancy (as confirmed by a positive pregnancy test result at the Screening Visit) and / or is breastfeeding.
✕. Participant has a known hypersensitivity to MC0518 and / or its excipients (dimethyl sulfoxide, human serum albumin, isotonic sodium chloride solution).
✕. Participant has a known hypersensitivity or any contraindication to the Investigator's choice BAT (extracorporeal photopheresis, anti thymocyte globulin, etanercept, infliximab, or ruxolitinib) and / or its excipients.
