  • Baseline QTcF > 500 ms
  • Concurrent active malignancy other than non-melanoma skin cancer or carcinoma in situ of the cervix, bladder cancer, or prostate cancer not requiring treatment. Subjects with previous malignancies are eligible if they have been disease-free for 2 years or more.
  • Unstable or severe uncontrolled medical condition that would, in the Investigator's judgment, increase the subject's risk to participating in this study.

Primary Outcome Measures
NameTimeMethod
Overall Response Rate (ORR) According to the 2007 Revised International Working Group (IWG) CriteriaUp to 14 months

ORR was defined as the percentage of participants achieving a complete response (CR) or partial response (PR) and assessed using the 2007 revised IWG criteria. The 2007 revised IWG criteria defined CR as the disappearance of all evidence of disease and PR as the regression of measurable disease and no new sites.

Secondary Outcome Measures
NameTimeMethod
Progression-free Survival (PFS)Up to 2 years

PFS was defined as the time from first dose to first progressive disease (PD) or death (progression date/death date - treatment start date + 1) or, for participants without PD or documented death, as the time from first dose to censoring date (censoring date - treatment start date + 1). The 2007 revised IWG criteria defined PD as any new lesion or increase by ≥50% of previously involved sites from nadir. The 2014 Lugano criteria defined PD as a progressive metabolic response (according to positron emission tomography-computed tomography \[PET-CT\]) and progressive disease (according to computed tomography \[CT\]). Results reported as months.

ORR At Specific Timepoints6, 12, 18, and 24 months after first dose of study intervention

ORR at 6, 12, 18, and 24 months after first dose of study intervention was defined as the percentage of participants achieving CR or PR at each timepoint and was assessed using both the 2007 revised IWG criteria and the 2014 Lugano criteria. The 2007 revised IWG criteria defined CR as the disappearance of all evidence of disease and PR as the regression of measurable disease and no new sites. The 2014 Lugano criteria defined CR as a complete metabolic response (according to PET-CT) and a complete radiologic response (according to CT) and PR as partial metabolic response (according to PET-CT) and partial remission (according to CT). The response was cumulative for each timepoint; a participant was considered a responder if their first response occurred up to the end of that timepoint.

Duration of Response (DOR)Up to 2 years

DOR was defined for participants with CR or PR as the time from the date of first documentation of response (CR or PR) to date of the first documentation of PD or death. The 2007 revised IWG criteria defined CR as the disappearance of all evidence of disease, PR as the regression of measurable disease and no new sites, and PD as any new lesion or increase by ≥50% of previously involved sites from nadir. The 2014 Lugano criteria defined CR as a complete metabolic response (according to PET-CT) and a complete radiologic response (according to CT), PR as partial metabolic response (according to PET-CT) and partial remission (according to CT), and PD as a progressive metabolic response (according to PET-CT) and progressive disease (according to CT). Results are reported as months.

Overall Survival (OS)Up to 2 years

OS was the time from first dose to death (death date - treatment start date + 1). Participants without documented death were censored at their last known alive date (last known alive date - treatment start date + 1). Results reported as months.

Lymph Node Response Rate (LNRR)14 months

LNRR was calculated as the percentage of participants achieving ≥50% decrease in the sum of the product of the diameters of target lymph nodes. The confidence interval for LNRR was calculated only for participants who had at least 1 nodal target lesion, using the Clopper-Pearson exact method for binomial proportions. Participants whose target lesions were all extranodal were excluded from this analysis.

Time To First Response (TTFR)Up to 14 months

For participants with CR or PR, TTFR was defined as the time from first dose of study intervention to time of first CR or PR and was calculated as: the date of first CR or PR - randomization date + 1. The 2007 revised IWG criteria defined CR as the disappearance of all evidence of disease and PR as the regression of measurable disease and no new sites. The 2014 Lugano criteria defined CR as a complete metabolic response (according to PET-CT) and a complete radiologic response (according to CT) and PR as partial metabolic response (according to PET-CT) and partial remission (according to CT). Results are reported as months.

Time To Treatment Failure (TTF)Up to 2 years

TTF was calculated as the time from first dose of study treatment to discontinuation for any reason (discontinuation date - treatment start date + 1). Participants who were still ongoing treatment at time of data cut were censored (last dose date - treatment start date + 1). Results reported as months.

ORR According to 2014 Lugano CriteriaUp to 14 months

ORR was defined as the percentage of participants achieving a CR or PR and was assessed using the 2014 Lugano criteria. The 2014 Lugano criteria defined CR as a complete metabolic response (according to PET-CT) and a complete radiologic response (according to CT) and PR as partial metabolic response (according to PET-CT) and partial remission (according to CT).
