About this study

Official title: Multicentric Phase II Trial to Evaluate the Efficacy and Safety of Ibrutinib in Combination With Rituximab in Patients With Indolent Clinical Forms of Mantle Cell Lymphoma

Phase II study with a two-stage design to evaluate efficacy and safety of ibrutinib in combination with rituximab (I+R) in untreated patients with indolent clinical forms of MCL.

An extensive biological study will be conducted in order to further characterize this population of MCL patients and evaluate the response obtained with the mutational profile of the tumor.

Read the detailed description

Patients with mantle cell lymphoma (MCL) have a median survival of 3-5 years despite treatment. Indeed, the best therapeutic approach for different patients with MCL remains to be established, coexisting different options of immunochemotherapy regimes which may include autologous transplantation in first-line treatment or rituximab maintenance.

Moreover, last years MCL starts to be recognized as a heterogeneous disease both from biological and clinical stand points. For instance, MCL cases with a non-nodal clinical presentation, usually have distinctive biological features such as SOX-11 negativity, hypermutated IGHV genes and a low number of genetic lesions associated. The outcome of these cases is much more favourable compared to conventional MCL, reaching median survivals over 7 to 10 years even receiving less intensive treatments. In addition to that, up to 30% of the patients with newly diagnosed MCL can be safely deferred from initial therapy until progression . Therapeutic abstention may be prolonged for more than one year in 50% of cases. These patients usually show longer survivals from the start of treatment compared to patients immediately treated after diagnosis. Therefore, all these observations indicate that there are indolent clinical forms in MCL, so its clinico-biological identification is crucial to tailor treatment appropriately. However, at present there is no consensus on the diagnostic criteria or treatment recommendations in cases of indolent MCL. This results in difficulties for the identification of these forms in the clinical practice as well as with a certain therapeutic in definition, as indolent forms of MCL can be treated either with therapeutic abstention until progression or receive immediate treatment with conventional or more intensive immuno-chemotherapy regimes, which may even include an autologous hematopoietic stem cell transplantation. With the emergence of new biological agents in the therapeutic arsenal of MCL arises the question whether a completely different approach with new drugs and chemotherapy-free could be more appropriate in selected subsets of patients such as indolent MCL forms.

    Measured: within 12 months after initiation of study treatment

  5. Overall survival

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing IBRUTINIB and Rituximab in people with Mantle Cell Lymphoma, run by Grupo Español de Linfomas y Transplante Autólogo de Médula Ósea at 15 sites in Spain.

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 13 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: under way, not looking for participants, as of the sponsor's last update on 27 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites in Spain. 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?

This study is still under way. Results are not available in the source record yet.

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?

Rate of complete remission (time frame: 12 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 NCT02682641, 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 27 Mar 2026.
