About this study

This is a phase 2, open-label, single institution trial of combination of intravenous (IV) ofatumumab and oral GSK2110183 in patients with relapsed or refractory Chronic Lymphocytic Leukemia (CLL). Patients must have received at least one prior line of therapy containing fludarabine (single-agent or combination therapy). During the initial 6 months Treatment Phase, ofatumumab will be administered weekly for 8 doses, then once every 4 week cycle for an additional 4 doses (dose and schedule identical to the pivotal phase 2 trial) and GSK2110183 will be given daily PO (Treatment Phase). There will be an initial 10 day lead-in with GSK2110183 alone prior to initiation of ofatumumab to allow for evaluation of changes in cell surface expression due to GSK2110183 and for GSK2110183 pharmacokinetic studies (Lead-in Phase). The official Cycle 1 Day 1 will start on the date of first dose of ofatumumab. Cycle duration = 4 weeks. Patients will be assessed for safety, disease assessment, response, and survival on day 1 of each cycle during the Treatment Phase. A formal review of safety data by the Data Safety Monitoring Board (DSMB) after the first 6 patients have completed cycle 1 of the Treatment Phase will be performed before continuing accrual. All patients achieving SD, PR or CR by the end of the Treatment Phase will proceed to the Maintenance Phase. Patients with PD at any time, including by the end of Treatment Phase, will be taken off study. During the Maintenance Phase, single-agent GSK2110183 will be administered daily for a maximum of 12 months (12 cycles). Maximum duration on any study drug is 18 months (18 cycles). During the Follow-up Phase, patients will be assessed for safety, disease assessment, response, and survival every 3 months through month 36 (year 3), or until subsequent CLL therapy or death, whichever comes first. Key indications for study withdrawal are progressive disease, intolerable toxicity, or completion of therapy

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Overall Response Rate, as Per the IWCLL 2008 Response Criteria

    IWCLL Response Criteria 2008-Hallek. Complete response (CR): requires peripheral blood lymphocytes < 4 x 109/L, absence of significant lymphadenopathy (>1.5cm), no organomegaly, normal CBC, bone marrow must be at least normocellular; Complete Remission with incomplete bone marrow recovery (CRi): fulfill all the criteria for CR but have persistent anemia, thrombocytopenia or neutropenia apparently unrelated to disease activity but related to drug toxicity; Partial Remission (PR): ≥ 50% decrease in the peripheral blood lymphocytes from baseline, > 50% reduction in the sum products of up to 6 lymph nodes, > 50% reduction in hepatomegaly and/or neutrophils > 1.5 x109/L, platelets > 100 x109/L, hemoglobin > 110 g/L; Stable Disease: Not CR, PR or PD (equivalent to nonresponse); Progressive Disease: Lymphadenopathy, or appearance of any new lesion/organomegaly, > 50% increase in the size of the liver and/or spleen, > 50% increase in the absolute number of circulating lymphocytes

    Measured: 36 months

Secondary outcomes (3)

  1. Stable Disease, Response Rate, Toxicity (as Graded Per NCI CTC Version 4.03)

    Measured: 36 months

  2. Median Progression Free Survival, Overall Survival

    Progression Free Survival (PFS) is defined as the length of time between the date of first dose of study treatment (GSK2110183) and the earliest date of disease progression or death due to any cause.

    Overall survival is defined as the length of time between the date of first dose of study treatment (GSK2110183) and death due to any cause.

    Measured: 36 months

  3. Median Duration of Response

    Duration of Response (DOR) is defined, for the subset of patients with a CR or PR, as the time from first documented evidence of CR or PR until first documented disease progression or death due to any cause. Duration of response will be summarized descriptively using Kaplan-Meier medians and quartiles.

    Measured: 36 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ofatumumab with GSK2110183 in people with Chronic Lymphocytic Leukemia (CLL), run by University Health Network, Toronto at 1 site in Canada.

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 11 inclusion and 28 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 24 Sep 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 24 Sep 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Overall Response Rate, as Per the IWCLL 2008 Response Criteria (time frame: 36 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01532700.

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 24 Sep 2019.
