Time frame
Assessed at Cycle 2, Day 1, and on Day 1 of every cycle thereafter; estimated median duration of follow-up was 8.1 months for Phase 1 and 31.7 months for Phase 2

What was measured

DOR is defined as the number of days from the date of first response of Partial Response (PR) or better to the date of first documented disease progression or death due to multiple myeloma, whichever occurs first. DOR was analyzed by Kaplan- Meier (K-M) methodology.

Analysis population: All enrolled participants who received venetoclax, had active disease at baseline, and achieved a response of PR or better

Groups in this outcome

Phase 1: Venetoclax 300 mg

Participants in the dose-escalation cohort received 300 mg of venetoclax daily on Days 1 -21 of each cycle after a 2-week lead-in period, during which venetoclax doses were increased weekly.

Phase 1: Venetoclax 600 mg

Participants in the dose-escalation cohort received 600 mg of venetoclax daily on Days 1 -21 of each cycle after a 2-week lead-in period, during which venetoclax doses were increased weekly.

Phase 1: Venetoclax 900 mg

Participants in the dose-escalation cohort received 900 mg of venetoclax daily on Days 1 -21 of each cycle after a 2-week lead-in period, during which venetoclax doses were increased weekly.

Phase 1: Venetoclax 1200 mg

Participants in the dose-escalation cohort received 1200 mg of venetoclax daily on Days 1 -21 of each cycle after a 2-week lead-in period, during which venetoclax doses were increased weekly.

Phase 1 Safety Expansion: Venetoclax 1200 mg

Participants in the safety expansion cohort received 1200 mg of venetoclax daily on Days 1 - 21 of each cycle after a 2-week lead-in period, during which venetoclax doses were increased weekly.

Phase 1 Combination: Venetoclax 800 mg/Dexamethasone 20 or 40 mg

Participants with t(11;14) translocation multiple myeloma received daily venetoclax at a dose of 800 mg (no lead-in period) on Days 1- 21 of each cycle concomitant with weekly dexamethasone at a dose of 40 mg (20 mg for those aged ≥ 75 years).

Phase 2 Expansion: Venetoclax 800 mg/Dexamethasone 20 or 40 mg

The Phase 2 cohort further explored the efficacy of venetoclax in combination with dexamethasone in relapsed or refractory participants with t(11;14) translocation multiple myeloma. Participants received daily venetoclax at a dose of 800 mg (no lead-in period) on Days 1- 21 of each cycle concomitant with weekly dexamethasone at a dose of 40 mg (20 mg for those aged ≥ 75 years).
