New hope for MDS patients? study tests MBG453 combo but ends early
NCT ID NCT03946670
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested adding an experimental drug called MBG453 to standard chemotherapy for people with a serious bone marrow disorder called myelodysplastic syndrome (MDS). The trial included 127 adults with high-risk MDS who could not have a stem cell transplant. The goal was to see if the combination could improve remission rates and delay disease progression, but the study was stopped early.

Inclusion Criteria: * Signed informed consent must be obtained prior to participation in the study. * Age ≥ 18 years at the date of signing the informed consent form (ICF)-. Morphologically confirmed diagnosis of a myelodysplastic syndrome (MDS) based on 2016 WHO classification (Arber et al 2016) by investigator assessment with one of the following Prognostic Risk Categories, based on the International Prognostic Scoring System (IPSS-R): * Very high * High * Intermediate with at least ≥ 5% bone marrow blast * Not eligible at the time of screening, for intensive chemotherapy according to the investigator, based on local standard medical practice and institutional guidelines for treatment decisions * Not eligible at the time of screening, for hematopoietic stem-cell transplantation (HSCT) according to the investigator, based on local standard medical practice and institutional guidelines for treatment decisions. * Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2 Exclusion Criteria: * Prior exposure to TIM-3 directed therapy at any time. Prior therapy with immune check point inhibitors (e.g. anti-CTLA4, anti-PD-1, anti-PD-L1, or anti-PD-L2), cancer vaccines are allowed except if the drug was administered within 4 months prior to randomization. * Previous first-line treatment for higher risk MDS with chemotherapy or any other antineoplastic agents including lenalidomide and hypomethylating agent (HMAs) such as decitabine or azacitidine. * History of severe hypersensitivity reactions to any ingredient of the study treatment (azacitidine, decitabine or MGB453) or their excipients, or to monoclonal antibodies (mAbs). * Currently using or used within 14 days prior to randomization of systemic, steroid therapy (\> 10 mg/day prednisone or equivalent) or any immunosuppressive therapy. Topical, inhaled, nasal, ophthalmic steroids are allowed. Replacement therapy, steroids given in the context of a transfusion are allowed and not considered a form of systemic treatment. * Investigational treatment for MDS received within 4 weeks prior to randomization. In case of a checkpoint inhibitor: 4 months minimum prior to randomization interval is necessary to allow enrollment. * Active autoimmune disease requiring systemic therapy (e.g.corticosteroids). * Live vaccine administered within 30 Days prior to randomization.
