Percentage of Participants with CR
CR or CR with incomplete bone marrow recovery (CRi) was determined by the investigator according to IWCLL 2008 criteria. CR requires all of the following: Peripheral blood lymphocytes below 4x10^9/L, absence of lymphadenopathy by physical examination and computed tomography (CT) scan, No hepatomegaly or splenomegaly, Absence of disease or constitutional symptoms, Blood counts of neutrophils >1.5*10^9/L, platelets >100*10^9/L and hemoglobin >110 g/L, Bone marrow at least normocellular for age without clonal infiltrate (except for Cri).

Progression-Free Survival (PFS) According to IWCLL 2008 Guidelines
PFS was determined according to IWCLL 2008 criteria and defined as the time from randomization to the first occurrence of progressive disease (PD) or death. Disease progression was characterized by at least one of the following: 1) >/= 50% increase in the absolute number of circulating lymphocytes to at least 5*10^9/L, 2) Appearance of new palpable lymph nodes (> 15 mm in longest diameter) or any new extra-nodal lesion; 3) >/= 50% increase in the longest diameter of any previous site of lymphadenopathy; 4) >/= 50% increase in the enlargement of the liver and/or spleen; 5) Transformation to a more aggressive histology.
Measured: Baseline up to approximately 5.75 years
Overall Survival (OS)
OS was defined as the time from randomization to death from any cause.
Measured: Baseline up to approximately 5.75 years
Number of Participants With Adverse Events
An adverse event is any untoward medical occurrence in a subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.
Measured: Up to approximately 5.75 years

What is this clinical trial studying?
A Phase 1 study testing Bendamustine, Obinutuzumab and Rituximab in people with Chronic Lymphocytic Leukemia, run by Genentech, Inc. at 12 sites in 3 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 12 sites in United States, France, Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants With Dose Limiting Toxicities (DLTs) (time frame: Schedule (Sch) A (venetoclax [V] introduced before other agents): Cycle 1 Day 1 (Cy1D1) to Cy1D21; Sch B (V introduced after other agents): Cy1D21 to Cy2D28; Cycle length = 28 days.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
