About this study

Official title: Sequential Triple Therapy With Ibrutinib, Obinutuzumab and Venetoclax in First and Second Line for Patients With Chronic Lymphocytic Leukemia

Background: Chronic Lymphocytic Leukemia (CLL) is the most common leukemia in the occidental countries. Until now, it is considered a chronic disease without a cure. The development of new molecular therapies have showed that the cure may be an option. This protocol propose a triple sequential therapy with three direct therapies for the leukemic cell: an inhibitor of Bruton´s tyrosine kinase (ibrutinib), a second generation monoclonal antibody versus CD20 (obinutuzumab) and a BCL-2 inhibitor (venetoclax) as treatment of first or second line in CLL.

Objective: Negativize the minimal residual disease and by this way obtain longer survivals (overall survival and relapse free survival).

Design: This is a multicenter, longitudinal, experimental, open, non-randomized and non-comparable study coordinated by the "Grupo Cooperativo de Hemopatías Malignas" situated on Hospital Angeles Lomas in Huixquilucan, México. The study, is a phase II clinical study that will employ three target therapy drugs in sequencing phases. It will start with a BTK inhibitor as induction, later an anti-CD20 will be used for consolidation and it will end with a BH3 analog as maintenance for one year. The primary outcome is the negativization of minimal residual disease.

Read the detailed description

The international recommendations indicate that the first line of treatment for patients <65 years old and with no significant comorbidities (fit patients) the known regime of FCR with recommendation of category 1 and later bendamustine with antiCD20 or ibrutinib. For patients >65 years old or not fit for intensive treatment it is recommended chlorambucil with obinutuzumab, monotherapy with ibrutinib, bendamustine with antiCD20 or chlorambucil with another antiCD20 like rituximab or ofatumumab. In case of patients with high-risk alterations of relapse due to positive MRD at the end of the treatment it is recommended a maintenance schedule with lenalidomide.

The antibodies against CD20 have shown through the years its activity in diverse alterations of B-cells. Rituximab was approved in 1998 for B-cells Non-Hodgkin lymphomas including CLL. Currently there are new anti-CD20 with more activity than rituximab. One of them is obinutuzumab which, by the monoclonal antibody engineering shows a greater affinity to the union of the epitope CD20 generating increased cellular cytotoxicity.

Bruton's tyrosine kinase (BTK), generates signaling cascades for the cell survival by the NF-KB and MAP kinases way, which leads to the transduction of the B cell receptor (BCR). Ibrutinib is a molecule that inhibits BTK inducing apoptosis in the B cells being currently used in the diverse mature B cell neoplasms.

Another therapeutic target is the BCL-2 protein (B-cell lymphoma 2) which is a key regulator in the apoptotic and it's compromised in the B cell neoplasms. Venetoclax is a mimetic drug to BH3 that blocks the function of BCL-2.

Based in the old and new drugs described in CLL, there is a great number of combinations that can be applied in the different phases of the disease as well as by risk stages and physical state of the patient. Before this scenario diverse CLL study groups proposes the strategy of sequencing in three phases (triple T) trying to prevent the development of leukemic subclones, minimize the use of chemotherapy that generates secondary mutations in CLL and other neoplasms. These type of treatment counts with the advantage of: 1) being available for patients physically fit or not due to the a limited toxicity of the drugs, 2) applying in an out-of-hospital environment and 3) adjusting the treatment according to the response to generate an effective cost in the new drugs. Thus, it is proposed the cytoreduction sequencing for 1 to 2 cycles, induction for 6 to 12 months and the MRD maintenance that could go from one year up to undefined with ibrutinib, obinutuzumab and venetoclax in that order.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ibrutinib, Obinutuzumab and Venetoclax in people with B-Cell Chronic Lymphocytic Leukemia and B-Cell Chronic Lymphocytic Leukemia in Relapse (Diagnosis), run by Grupo Cooperativo de Hemopatías Malignas at 1 site in Mexico.

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 6 inclusion and 13 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 2 Feb 2021. 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 Mexico. 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?

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?

Best response obtained (time frame: Two months after finishing the triple sequencing therapy). 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 NCT03755947, which also lists 12 linked publications.

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 2 Feb 2021.
