Brief Summary:
Multicentric phase II trial to evaluate efficacy and safety of ibrutinib in combination with rituximab, gemcitabine, oxaliplatin and dexamethasone followed by Ibrutinib maitenance in patients with refractory/relapsed non-GCB DLBCL non candidates to autologous stem-cell transplantation (ASCT) An extensive biological study will be conducted in order to further characterize this population of DLBCL patients and correlate the response obtained with the biological profile of the tumor.

Condition or disease Intervention/treatment Phase
Diffuse Large B-Cell Lymphoma Drug: Ibrutinib Drug: Rituximab Drug: Gemcitabine Drug: Oxaliplatin Drug: Dexamethasone Phase 2

Detailed Description:

The use of highly effective rituximab-containing therapy for treating diffuse large B-cell lymphoma (DLBCL) makes it more difficult to salvage relapsed or refractory patients. In addition, patients with advanced age or significant comorbidities, who are consequently not candidates for high-dose consolidative therapy, have a very poor prognosis. Prospective studies investigating new salvage regimens are essential.

The combination of rituximab, gemcitabine and oxaliplatin (R-GEMOX) is an effective salvage regimen for patients with relapsing or refractory DLBCL, with a favourable toxicity profile for unfit and/or elderly patients. Ibrutinib, an oral Bruton's tyrosine kinase inhibitor, is a potent killer of ABC DLBCL cell lines in vitro and in xenografts.

It is expected that the combination of ibrutinib with R-GEMOX-Dexa could be effective and well tolerated. Thus, it is proposed an open-label, non-randomized, multicentre, phase II trial, to investigate the safety and efficacy of the combination of ibrutinib with rituximab, gemcitabine, oxaliplatine and dexamethasone followed by ibrutinib maintenance as salvage therapy for patients with relapsed or refractory non-GCB DLBCL non-candidates to stem cell transplant.

Primary Outcome Measures :
  1. Overall Response (OR) rate (complete remission + partial response) measured by PET(Positron Emission Tomography)/CT imagen scan [ Time Frame: Treatment responses will be evaluated 30 days after end of study treatment wich can be ocurred after 2 years and 4 months ]
    OR will be assessed by Lugano Classification: Revised Criteria for Response Assessment (Cheson et al. 2014)


Secondary Outcome Measures :
  1. CR rate during induction and maintenance phases. [ Time Frame: 2 years ]
    Complete treatment responses evaluation during 21-35 days after initiation of 6 or 8 cycle of study treatment (depend of treatment responses obtained from cycle 4) and 30 days after end of study treatment which can be occurred after 2 years and 4 months

  2. Conversion rate from SD (Stable Disease) or PR to PR or CR by PET/CT imagen scan [ Time Frame: 2 years ]
    Responses conversion rate evaluation after 30 days of the end of the maintenance treatment which can be occurred after 2 years of maintenance study treatment

  3. Response duration [ Time Frame: Response duration will be evaluated at any time during the study when tumor response is documented or after end of study treatment which can be occurred after 2 years and 4 months. ]
    Response duration defined as the time from the documentation of tumor response to disease progression or death, in the event of no documented recurrence, or start of a new anti - lymphoma treatment because of refractory or persistent disease.

  4. Progression free survival [ Time Frame: Progression free survival will be evaluated at any time during the study when first documentation of recurrence, progression, or death or after end of study treatment which can be occurred after 2 years and 4 months ]
    Progression free survival defined as the time between start of treatment and the first documentation of recurrence, progression, or death in the event of no documented recurrence, or start of a new anti - lymphoma treatment, due a refractory or persistent disease

  5. Event-free survival [ Time Frame: 2 years ]
    Event-free survival defined as the time between start of treatment and the first documentation of adverse events and serious adverse events graded according to NCI CTCAE v4.0

  6. Overall survival [ Time Frame: 2 years ]
    Overall survival is defined as the time between the start of treatment and death from any cause. Patients that are withdrawn from the trial or lost of follow-up, will be censored with the date of last contact. Patients who are still alive at the end of the study will be censored at that time.

  7. Safety and tolerability of ibrutinib in combination rituximab, gemcitabine, oxaliplatin and dexamethasone [ Time Frame: 2 years ]
    Safety and tolerability will be assessed during any phase of study treatment and 30 days after end of study treatment which can be occurred after 2 years and 4 months and will be classified according to the Common Toxicity CNC
