Experimental: Obinutuzumab +/- bendamustine then obinutuzumab + venetoclax
Debulking Period: Obinutuzumab with or without bendamustine (bendamustine administered in participants with high tumor load as described in the protocol) during the debulking period (up to 6 cycles). Treatment Period: Venetoclax + obinutuzumab regimen initiated when participant achieves low tumor burden during debulking period, or if the participant has not achieved low tumor burden status after 6 cycles of debulking, the participant may proceed to venetoclax per the discretion of the treating provider after discussion with the study physician. During this regimen period, participants to receive obinutuzumab in combination with venetoclax for 5 months then venetoclax therapy alone to continue for a total duration of up to 53 weeks. |
Drug: Obinutuzumab
intravenous
Other Name: Gazyva Drug: Bendamustine intravenous

Primary Outcome Measures :
- Percent of Participants Achieving Low Tumor Burden Status with induction of Obinutuzumab or Obinutuzumab plus Bendamustine (Debulking Period) [ Time Frame: Up to approximately 24 weeks after initial dose of study drug ]Low tumor burden is defined by peripheral lymphocyte counts of < 25,000 and all lymph nodes < 5 cm per CT scans.
- Complete Remission Rate (CR) and Complete Remission with Incomplete Marrow Recovery (CRi) [ Time Frame: Up to approximately 65 weeks after initial dose of venetoclax ]Defined as the proportion of subjects who achieved CR or CRi (per the 2008 Modified International Workshop on Chronic Lymphocytic Leukemia National Cancer Institute-sponsored Working Group [IWCLL NCI-WG] criteria).
Secondary Outcome Measures :
- Overall Response Rate (ORR) [ Time Frame: Up to approximately 3.5 years after initial dose of study drug ]ORR is defined as the proportion of participants with an overall response (CR, CRi, nodular partial remission [nPR] plus partial remission [PR]) per the 2008 Modified IWCLL NCI-WG criteria.
- Duration of Response (DoR) [ Time Frame: Up to approximately 3.5 years after initial dose of study drug ]DOR defined as the number of days from the date of first response (CR, CRi, nPR, or PR) (per the 2008 Modified IWCLL NCI-WG criteria) to the date of disease progression or death. All disease progression will be included regardless whether the event occurred during or after the participant was taking any study drug (either venetoclax, obinutuzumab, or bendamustine).
- Progression-Free Survival (PFS) [ Time Frame: Up to approximately 3.5 years after initial dose of study drug ]PFS is defined as the number of days from the date of first dose of any study drug (either venetoclax, obinutuzumab, or bendamustine) to the date of disease progression or death, whichever occurs first. All disease progression will be included regardless whether the event occurred during or after the participant was taking any study drug.
- Time to Progression (TTP) [ Time Frame: Up to approximately 3.5 years after initial dose of study drug ]TPP is defined as the number of days from the date of first dose of any study drug (either venetoclax, obinutuzumab, or bendamustine) to date of disease progression. All disease progression will be included regardless whether the event occurred during or after the participant was taking any study drug.
- Overall Survival (OS) [ Time Frame: Up to approximately 3.5 years after initial dose of study drug ]OS is defined as number of days from the date of first dose of any study drug (either venetoclax, obinutuzumab, or bendamustine) to the date of death.
- Undetectable Minimal Residual Disease (UMRD) Rate [ Time Frame: Up to approximately 3.5 years after initial dose of study drug ]UMRD defined as less than one CLL cell per 10,000 leukocytes (or below 10^-4). Rate of UMRD status will be defined as the percentage of participants who have UMRD.
