What was measured

Toxicity was graded according to the National Cancer Institute - Common Terminology Criteria for Adverse Events Version 4.03. DLT criteria that apply to Regimens A and B: * Grade 3 non-hematologic toxicity preventing the administration of \> 1 dose of bortezomib or daratumumab during the 1st cycle. * Grade 4 or greater non-hematologic toxicity. * Grade 4 thrombocytopenia (platelet count \< 25,000 cells/ mm\^3) preventing the administration of \> 1 dose of bortezomib or daratumumab during the 1st cycle or with clinically significant bleeding during the 1st cycle. * Grade 4 neutropenia (ANC \< 500 cells/mm\^3), lasting more than 7 days during the 1st cycle. * Greater than 14 days' delay to meet the criteria for the start of a new cycle (Cycle 2) due to toxicity.

Analysis population: Only participants included in the DLT Analysis set were included in this analysis. The DLT Analysis Set was defined as all participants in Phase 1 that complete Cycle 1 of therapy or are discontinued due to a DLT event.

Groups in this outcome

Regimen A - Melflufen 30mg + Bortezomib + Dexamethasone

Participants were administered IV melflufen at a dose of 30 mg on Day 1 of each 28-day cycle in combination with SQ bortezomib at a dose of 1.3mg/m\^2 on Days 1, 4, 8, and 11 and dexamethasone PO at a dose of 20 mg (12 mg if the participants is ≥ 75 years of age) on Days 1, 4, 8, and 11 and 40 mg (20 mg if the participants is ≥ 75 years of age) on Day 15 and 22 of each 28-day cycle.

Regimen A - Melflufen 40mg + Bortezomib + Dexamethasone

Participants were administered IV melflufen at a dose of 40 mg on Day 1 of each 28-day cycle in combination with SQ bortezomib at a dose of 1.3mg/m\^2 on Days 1, 4, 8, and 11 and dexamethasone PO at a dose of 20 mg (12 mg if the participants is ≥ 75 years of age) on Days 1, 4, 8, and 11 and 40 mg (20 mg if the participants is ≥ 75 years of age) on Day 15 and 22 of each 28-day cycle.

Regimen B - Melflufen 30mg + Daratumumab + Dexamethasone

Participants were administered IV melflufen at a dose of 30 mg on Day 1 of each 28-day cycle in combination with IV daratumumab at a dose of 16 mg/kg weekly for 8 doses, every other week for 8 doses and then once every 4 weeks. Participants were also administered dexamethasone orally (PO) at a dose of 40 mg weekly (20 mg weekly if the participants is ≥ 75 years of age).

Regimen B - Melflufen 40mg + Daratumumab + Dexamethasone

Participants were administered IV melflufen at a dose of 40 mg on Day 1 of each 28-day cycle in combination with IV daratumumab at a dose of 16 mg/kg weekly for 8 doses, every other week for 8 doses and then once every 4 weeks. Participants were also administered dexamethasone orally (PO) at a dose of 40 mg weekly (20 mg weekly if the participants is ≥ 75 years of age).
