Chronic Lymphocytic LeukemiaPhase 1NCT02611908
Obinutuzumab With High-dose Ibrutinib for the Treatment of Patients With Chronic Lymphocytic Leukemia With Progressive Disease on Single Agent Ibrutinib.
A Phase 1 study testing ibrutinib and obinutuzumab in people with Chronic Lymphocytic Leukemia, run by Michael Choi.
Trial summary
The purpose of the study is to investigate whether the combination of obinutuzumab and ibrutinib (administered up to 840 mg per day) might be useful for the treatment of CLL or SLL that is not responding or no longer responding to treatment with ibrutinib alone. Read more about this study

About this study
Official title: A Phase 1 Clinical Trial to Evaluate Obinutuzumab With High-dose Ibrutinib for the Treatment of Patients With Chronic Lymphocytic Leukemia With Progressive Disease on Single Agent Ibrutinib.
The purpose of the study is to investigate whether the combination of obinutuzumab and ibrutinib (administered up to 840 mg per day) might be useful for the treatment of CLL or SLL that is not responding or no longer responding to treatment with ibrutinib alone. The study will evaluate whether this regimen can reduce the amount of cancerous cells in the body. Subjects will be treated with ibrutinib at a dose of up to 840 mg a day by mouth, as well as obinutuzumab infusions. Although both of these agents are approved by the FDA for the treatment of CLL or SLL, the combination and the dosing schedule of ibrutinib are considered experimental.
Read the detailed description
This is phase 1 study for patients with CLL or small lymphocytic lymphoma (SLL) experiencing disease progression on single ibrutinib. This study will evaluate the optimal ibrutinib dose (including doses higher than 420 mg) when combined with obinutuzumab.
During the screening period, patients will continue on ibrutinib at their previous tolerated dose, unless required to stop (e.g.: by a preceding clinical trial).
On cycle 1, day 1, the dose of ibrutinib will be assigned based on the dose cohort. Patients in cohort 1 will receive ibrutinib 420 mg PO daily. Patients in cohort 2 will receive ibrutinib 560 mg PO daily. Cohort 3 will be 700 mg PO daily. Cohort 4 will be 840 mg PO daily.
On cycle 1, day 1, patients will also initiate treatment with obinutuzumab (100 mg on day 1, 900mg on day 2, 1000mg day 8, 15, 28 then q 28 days for a total of 8 doses).
The primary safety endpoint is determination of DLTs during the first 28 days. The primary efficacy endpoint of overall response rate will be assessed 2 months after the final dose of obinutuzumab.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing ibrutinib and obinutuzumab in people with Chronic Lymphocytic Leukemia, run by Michael Choi.
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 7 inclusion and 22 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: withdrawn, as of the sponsor's last update on 25 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.
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 was withdrawn before enrolling participants, so there are no results.
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?
Maximum tolerated dose (time frame: 2 months). 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?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Jan 2019.
