About this study

In plain language

This study tests repeat treatment with venetoclax pills and obinutuzumab given through a vein (IV). It is for adults whose chronic lymphocytic leukemia (CLL), a cancer of blood cells, came back after earlier treatment with venetoclax and an anti-CD20 antibody. Researchers will check changes in the cancer and side effects.

Chronic lymphocytic leukemia (CLL) is the most common leukemia (cancer of blood cells). The purpose of this study is to assess retreatment with venetoclax-obinutuzumab (VenG) in participants previously treated with fixed duration first-line (IL) therapy of venetoclax in combination with an anti-CD20 antibody +/- X (where X is any additional drug). Adverse events and change in disease activity will be assessed. Venetoclax is an approved drug for the treatment of CLL. Study doctors put the participants in 1 of 2 groups, called cohorts, based on when symptoms of CLL came back after previous treatment in first-line. Approximately 75 adult participants with CLL who have been treated with venetoclax in combination with an anti-CD20 antibody +/- X will be enrolled in the study in approximately 60 sites worldwide. Participants will receive intravenous (IV) obinutuzumab + oral venetoclax (VenG) in 28-day cycles for a total of 6 cycles per cohort, followed by 6 to 18 cycles of venetoclax alone, for a total treatment of 12 to 24 cycles, depending on the cohort. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

Compensation is read from the study's own description and may be missing — always confirm with the study team.

Eligibility

Who can join

  • Have a confirmed diagnosis of CLL that needs treatment under standard medical guidelines.
  • Finished a first CLL treatment with venetoclax and an anti-CD20 antibody, with or without other drugs, for a set length of time. An anti-CD20 antibody is a drug that targets certain blood cells.
  • Have medical records showing that the cancer partly or fully improved after that treatment.
  • The cancer worsened 12–24 months after the last venetoclax dose for Group 2, or more than 24 months after the last dose for Group 1.

Who can't join

  • Had any other CLL treatment after finishing the earlier treatment with venetoclax and an anti-CD20 antibody, with or without other drugs.

Simplified for readability. The official criteria below are what the study team uses.

Official eligibility criteria

Inclusion Criteria: * Documented diagnosis of chronic lymphocytic leukemia (CLL) that requires treatment for CLL according to International Workshop for Chronic Lymphocytic Leukemia (iwCLL) 2018 criteria. * Previously completed venetoclax + anti-CD20 antibody +/- X regimen as a fixed duration first-line (1L) therapy and achieved documented response, defined as complete remission, complete remission with incomplete marrow recovery, partial remission, or nodular partial remission. * More than 24 months (Cohort 1) or 12-24 months (Cohort 2) have elapsed between last dose of venetoclax and disease progression after completion of 1L treatment. Exclusion Criteria: \- Received intervening treatment for CLL after completing previous treatment with a venetoclax + anti-CD20 antibody +/- X regimen.
