About this study

Official title: A Phase II Study of Buparlisib in Patients With Relapsed and Refractory Chronic Lymphocytic Leukemia

The purpose of this study is to find out what effects a new drug, buparlisib, has on chronic lymphocytic leukemia.

Read the detailed description

Buparlisib has been shown to shrink tumours in animals. It has been studied in some people and seems promising but it is not clear if it can offer better results than standard treatment.

The standard or usual treatment for this disease is chemotherapy, targeted therapy or radiation, either alone or in combination.

Being tested
Buparlisib
Medical subject headings
Leukemia, Lymphocytic, Chronic, B-Cell

What is being measured

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

  1. Overall Response Rate

    To determine the overall response rate (complete + partial response, as defined in the protocol) to oral buparlisib in patients with relapsed and refractory chronic lymphocytic leukemia.

    Complete Response (CR): CR requires all of the criteria listed on page 31 of the protocol, maintained for a period of at least 8 weeks.

    Partial Response (PR): To define a PR, at least 1 of the criteria of Group A plus 1 of the criteria of Group B listed on page 32 of the protocol must be met and persist for ≥ 8 weeks, in the absence of any criteria definitive of progressive disease.

    Measured: 30 months

Secondary outcomes (1)

  1. Progression Free Survival

    Progression-free survival (PFS) is defined as the time in months from study entry until disease progression or death.

    Measured: 30 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Buparlisib in people with Chronic Lymphocytic Leukemia, run by Canadian Cancer Trials Group at 6 sites 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 26 inclusion and 34 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 22 Aug 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites 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 13 Aug 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 (time frame: 30 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 NCT02340780, which also lists 1 linked publication.

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 22 Aug 2023; AzTrials last refreshed its copy on 7 Nov 2026.
