This research study is trying to determine which patients with newly diagnosed or relapsed/refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL), as grouped by their risk for tumor lysis syndrome (TLS), are able to safely tolerate an accelerated, daily venetoclax dose ramp-up rather than the standard approved schedule (5-week dose ramp-up).
The name of the study drug involved in this study is:
- Venetoclax
The following drugs may also be included in some participants treatment regimen:
- Obinutuzumab
- Rituximab

Chronic Lymphocytic Leukemia Small Lymphocytic Lymphoma | Drug: Venetoclax Drug: Obinutuzumab Drug: Rituximab | Phase 1 |
This is an open label phase Ib study of an accelerated venetoclax ramp-up in patients with CLL/SLL in either the front-line or relapsed/refractory setting. This clinical trial is testing a new dosing schedule of a drug that is normally dosed in a different fashion. As such, venetoclax is considered an investigational drug when given in this new schedule. "Investigational" means that the drug is being studied. The U.S. Food and Drug Administration (FDA) has approved venetoclax as a treatment option for CLL or SLL but the approval is based on a different schedule.
Venetoclax is an oral drug inhibitor of BCL-2, a protein that regulates the death of cells in the body. It has been FDA approved with or without rituximab for the treatment of adult patients with CLL/SLL who have received at least one prior therapy, with obinutuzumab for frontline therapy of CLL/SLL, as well in combination with azacitabine, decitabine, or low-dose cytarabine for the treatment of adults with newly diagnosed acute myeloid leukemia (AML).
Venetoclax is typically started at a low dose and increased on a weekly basis, over 5 weeks, to the desired dose for patients with CLL/SLL.This study is trying to determine if patients can safely increase the venetoclax dose in the hospital on a daily basis, over 5 days rather than weekly, and which patients, grouped by their risk for TLS, with newly diagnosed or relapsed/refractory CLL/SLL, are able to safely tolerate this accelerated, daily venetoclax dose ramp-up.
The research study procedures include screening for eligibility and study treatment including evaluations and follow up visits.
All participants will be actively followed for approximately 3 months. Following completion of the active study period, participants will be encouraged to return for a response evaluation. Following this, patients will enter a long-term follow up period where they will be observed for a maximum of 5 years.
It is expected that about 40 people will take part in this research study.

Experimental: Venetoclax
Participants will be separated into two cohorts: Cohort A: Patients at low risk for TLS. Cohort B: Patients with both median and high risk for TLS. Five (5) participants from cohort A will be initially enrolled, if these first 5 participants tolerate the accelerated ramp-up, cohorts A and B will enroll simultaneously. All participants will be hospitalized and receive venetoclax daily with accelerated dose increases over 5 days to reach full dose. After reaching full dose, participants will be discharged and continue daily venetoclax at home. Per doctor assessment, some participants may also receive rituximab or obinutuzumab as part of the treatment regimen with venetoclax. Rituximab: Given every 28 days starting on the second study cycle and continuing for up to 6 cycles as per standard of care. Obinutuzumab: Days 1, 2, 8, and 15 of cycle 1 and once every 28 days there after for up to 6 cycles as per standard of care. |
