What was measured

The EQ-5D self-report questionnaire is a standardized measure of health status developed by the EuroQoL Group. It consists of the EQ-5D descriptive system and a visual analogue scale (VAS), EQ-VAS. The EQ-5D descriptive system measures a participants' health state on 5 dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has 3 levels, reflecting "no problems", "some problems", and "extreme problems". The EQ-VAS records the respondent's self-rated health on a scale from 0 (worst imaginable health state) to 100 (best imaginable health state); higher scores indicate a better health state. EQ-5D summary index is obtained with a formula that weights each level of the dimensions. The index-based score is interpreted along a continuum of 0 (death) to 1 (perfect health).

Analysis population: ITT population. Although only 143 participants were treated in the Defined Investigator's Choice of Chemotherapy arm, all 162 randomized participants were included in the ITT population.

Groups in this outcome

Inotuzumab Ozogamicin

Participants were treated with inotuzumab ozogamicin at a starting dose of 1.8 mg/m\^2 (according to body surface area) per cycle with a divided-dose regimen using 3 weekly administrations. Participants received 0.8 mg/m\^2/cycle on Week 1 (Day 1), followed by 0.5 mg/m\^2 on Week 2 (Day 8) and Week 3 (Day 15) of a 21-day cycle, and administered as an intravenous infusion over 60 minutes. For participants who achieved a CR or CRi, or to allow recovery from toxicity, the length of Cycle 1 could be extended up to 28 days (ie, 1 week treatment-free interval starting on Day 21). For participants who achieved CR or CRi, the inotuzumab ozogamicin dose administered on Week 1 was reduced to 0.5 mg/m\^2 (for a total cycle dose of 1.5 mg/m\^2/cycle) for Cycles 2 through 6 (maximum number of cycles permitted). For Cycles 2 through 6, the cycle length was 28 days for all participants (regardless of remission status).

Defined Investigator's Choice of Chemotherapy

Participants received fludarabine, cytarabine, granulocyte-colony stimulating factor (FLAG), mitoxantrone + cytarabine (MXN/Ara-C), or high-dose cytarabine (HIDAC), according to the Investigator's choice.
