What was measured

The MTD was defined as the highest carfilzomib dose at which \< 33% of participants had a treatment-related DLT during the first 28-day cycle. A DLT was categorized as nonhematologic or hematologic and defined as follows: Nonhematologic: * ≥ grade 3 nonhematological toxicity (excluding nausea, vomiting, diarrhea, fatigue lasting \< 14 days, increased serum creatinine or electrolyte abnormalities not clinically significant or requiring treatment) * ≥ grade 3 acute kidney injury (creatinine \> 3 x baseline or \> 4.0 mg/dL) lasting \> 72 hours * ≥ grade 3 nausea, vomiting, or diarrhea uncontrolled by maximal antiemetic/antidiarrheal therapy Hematologic: * grade 4 neutropenia (absolute neutrophil count \[ANC\] \< 500/mm³) for \> 7 days * febrile neutropenia (ANC \< 1000/mm³ with a fever ≥ 38.3ºC) of any duration * grade 4 thrombocytopenia (\< 25 000/mm³) for \> 14 days, despite holding treatment * grade 3 or 4 thrombocytopenia (\< lower limit of normal) associated with \> grade 1 bleeding

Analysis population: Participants in phase 1 who received at least 1 dose of any investigational product (carfilzomib or dexamethasone).

Groups in this outcome

Phase 1 Carfilzomib 45 mg/m²

Participants received carfilzomib administered by intravenous (IV) infusion on days 1, 8 and 15 of each 28-day cycle. The carfilzomib dose was 20 mg/m² on day 1 of cycle 1; thereafter, subsequent carfilzomib dosing was 45 mg/m². Participants also received 40 mg dexamethasone IV or orally on days 1, 8, 15 and 22 for the first 8 cycles; starting with cycle 9, dexamethasone was administered only on days 1, 8, and 15.

Phase 1: Carfilzomib 56 mg/m²

Participants received carfilzomib administered by intravenous (IV) infusion on days 1, 8 and 15 of each 28-day cycle. The carfilzomib dose was 20 mg/m² on day 1 of cycle 1; thereafter, subsequent carfilzomib dosing was 56 mg/m². Participants also received 40 mg dexamethasone IV or orally on days 1, 8, 15 and 22 for the first 8 cycles; starting with cycle 9, dexamethasone was administered only on days 1, 8, and 15.

Phase 1: Carfilzomib 70 mg/m²

Participants received carfilzomib administered by intravenous (IV) infusion on days 1, 8 and 15 of each 28-day cycle. The carfilzomib dose was 20 mg/m² on day 1 of cycle 1; thereafter, subsequent carfilzomib dosing was 70 mg/m². Participants also received 40 mg dexamethasone IV or orally on days 1, 8, 15 and 22 for the first 8 cycles; starting with cycle 9, dexamethasone was administered only on days 1, 8, and 15.

Phase 1: Carfilzomib 88 mg/m²

Participants received carfilzomib administered by intravenous (IV) infusion on days 1, 8 and 15 of each 28-day cycle. The carfilzomib dose was 20 mg/m² on day 1 of cycle 1; thereafter, subsequent carfilzomib dosing was 88 mg/m². Participants also received 40 mg dexamethasone IV or orally on days 1, 8, 15 and 22 for the first 8 cycles; starting with cycle 9, dexamethasone was administered only on days 1, 8, and 15.
