Non-hematologic criteria, excluding corneal toxicity, comprise Grade 3-5 toxicities, with exceptions for manageable nausea, vomiting, or diarrhea, controlled Grade 3 hypertension, and events linked to disease progression. Tumor lysis syndrome (TLS) of Grade 3 or 4, successfully managed within 7 days without end-organ damage, is considered. Corneal toxicity, assessed by the GSK corneal grading scale at Grade 4, is a DLT. Other organ-specific toxicities, notably liver toxicity meeting GSK stopping criteria, also qualify as DLTs. Severity was graded using National Cancer Institute - Common Terminology Criteria for Adverse Events (version 5.0).","groups":[{"description":"Participants with Relapsed/Refractory Multiple Myeloma (RRMM) received 1.9 milligram (mg)/kilogram (kg) belantamab mafodotin intravenous (IV) infusion as powder for solution once every 3 weeks (Q3W) infused over 30- 60 minutes on day 1 of 21-day cycles in combination with 500 mg dostarlimab as a 30-minute IV infusion 1 hour after belantamab mafodotin end of infusion (EOI) on day 1 of 21-day cycles (Q3W).","id":"OG000","title":"1.9 mg/kg Belantamab Mafodotin + 500mg Dostarlimab"}],"paramType":"COUNT_OF_PARTICIPANTS","populationDescription":"DLT Evaluable Population included participants in DE who have received the first course of treatment containing both agents within a sub-study and followed up within cycle 1 (Each cycle is of 21 days) or withdrew within cycle 1 due to an AE meeting the definition of a DLT.","reportingStatus":"POSTED","timeFrame":"Up to 21 days","title":"DE Phase: Number of Participants With Dose Limiting Toxicities (DLT)","type":"PRIMARY","unitOfMeasure":"Participants"}
