PRIMARY outcome

Population: Due to the early termination of the study, efficacy data were not available for all participants, and therefore the prespecified analyses were not conducted.

Overall response rate (ORR) was defined as the proportion of participants who achieve a confirmed complete or partial response. ORR was to be assessed by an independent review committee (IRC).

Outcome measures

Outcome data not reported

SECONDARY outcome

Population: Due to the early termination of the study, efficacy data were not available for all participants, and therefore the prespecified analyses were not conducted.

Duration of response (DOR) was defined as the interval from the first documentation of confirmed complete response or partial response (by IRC) to the first documentation of definitive disease progression or death from any cause. Definitive disease progression is chronic lymphocytic leukemia (CLL) progression based on standard criteria, excluding lymphocytosis alone.

Outcome measures

Outcome data not reported

SECONDARY outcome

Population: Due to the early termination of the study, efficacy data were not available for all participants, and therefore the prespecified analyses were not conducted.

Nodal response rate was defined as the proportion of participants who achieve a 50% decrease from baseline in the sum of the products of the greatest perpendicular diameters of index lesions. Nodal response rate was to be assessed by an IRC.

Outcome measures

Outcome data not reported

SECONDARY outcome

Population: Due to the early termination of the study, efficacy data were not available for all participants, and therefore the prespecified analyses were not conducted.

Complete response rate was defined as the proportion of participants who achieve a confirmed complete response. Complete response rate was to be assessed by an IRC.

Outcome measures

Outcome data not reported

SECONDARY outcome

Population: Due to the early termination of the study, efficacy data were not available for all participants, and therefore the prespecified analyses were not conducted.

Progression-free survival (PFS) was defined as the interval from first dose of study drug to the first documentation of definitive disease progression or death from any cause. Definitive disease progression is CLL progression based on standard criteria, excluding lymphocytosis alone. PFS was to be assessed by an IRC.

Outcome measures

Outcome data not reported

SECONDARY outcome

Population: Due to the early termination of the study, efficacy data were not mature for all participants, and therefore the prespecified analyses were not conducted.

Overall survival was defined as the interval from the start of study treatment to death from any cause.

Outcome measures

Outcome data not reported

SECONDARY outcome

Population: Due to the early termination of the study, efficacy data were not available for all participants, and therefore the prespecified analyses were not conducted.

Minimal residual disease (MRD) negativity rate was defined as the proportion of participants with MRD \< 10\^-4 assessed by flow cytometry in bone marrow at Week 36 after therapy initiation. For participants receiving the final dose of rituximab after the original scheduled date, the MRD assessment will be performed no fewer than 12 weeks after the last dose of rituximab.
