Stem cell transplant vs. standard care in myeloma relapse: a Head-to-Head trial
NCT ID NCT05675319
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether a donor stem cell transplant (allogeneic) works better than standard drug therapy for people with multiple myeloma that came back after initial treatment. It included adults aged 18-70 with a compatible donor. The trial was stopped early, so results are limited.

Inclusion Criteria: Patients eligible for study inclusion must meet criteria 1- 7 at registration and all of the following criteria before randomization: 1. Multiple Myeloma 2. Age 18 - 65 years 3. A signed informed consent form must be obtained before participation in the study 4. Age 66 - 70 years, if comorbidity index according to Sorror score = 0 and ECOG ≤ 1 5. 1st relapse/ progression according to IMWG criteria after first-line therapy (consisting of induction therapy followed by autologous transplantation once or twice and maintenance therapy), Additionally: meeting the need for treatment based on the SLiM-CRAB-criteria 6. Negative pregnancy test in female patients 7. Maximum of 1 cycle salvage therapy prior to study inclusion 8. Availability of a fully compatible stem cell donor (HLA-ident. Sibling or 10/10 MUD or 9/10 MMUD if mismatch affects DQB) after 3 cycles salvage therapy 9. CR/PR or SD according to IMWG-criteria after 3 cycles salvage therapy within the study Exclusion Criteria: Patients are excluded from the study if any one of criteria 1-6 are met at registration and if criterion 7 is met before randomization: 1. Non-sufficient organ function defined as: Bilirubin (in the absence of Meulengracht's disease), SGPT or SGOT ≥3 higher than normal values Cardiac ejection fraction ≤ 50% GFR \< 30 ml/min DLCO \< 35 % or continuous oxygen dependency 2. Active hepatitis B or C infection or uncontrolled HIV infection 3. Other, active malignant disease 4. Prior treatment with allogeneic stem cells 5. Participation in a clinical trial or taking an IMP within 30 days or five times the half-life of the IMP, whichever is longer, prior to registration 6. Positive serum pregnancy test at screening and before first treatment or breastfeeding 7. PD under salvage therapy
