LOC-R01 Study of Lenalidomide and Ibrutinib in Association With Rituximab-Methotrexate Procarbazine Vincristin (R-MPV)

LOC-R01: Randomized Phase IB/II Study of Escalating Doses of Lenalidomide and Ibrutinib in Association With R-MPV as a Targeted Induction Treatment for Patients Aged 18 to 60 (up to 65 for Phase II) With a Newly Diagnosed Primary Central Nervous System Lymphoma

• Status: Active Not Recruiting
• Phase: Phase 1 / Phase 2
• Study type: Interventional
• Enrollment: 118 (estimated)
• Sponsor: Institut Curie · Academic / Other
• Sex: All
• Age: 18 Years – 65 Years
• Healthy volunteers: Not accepted

Summary

This study is to improve the first-line induction chemotherapy, by combining either Ibrutinib, or Lenalidomide, to a conventional immuno- chemotherapy of R-MPV type (Rituximab-Methotrexate-Procarbazine-Vincristine). This is a randomized Phase II trial, preceded by a dose escalation phase Ib. The objective of the phase Ib is to rule out any limiting toxicity of the new treatment associations, and to determine the recommended dose of Lenalidomide and Ibrutinib to be used in the phase II. In the phase II study, patients will receive 4 cycles of R-MPV + Lenalidomide or 4 cycles of R-MPV + Ibrutinib. The therapeutic response will be evaluated after the 2nd and the 4th cycle. Patients in good therapeutic response will proceed to the consolidation phase with Autologous Stem Cell Transplantation (ASCT).

Detailed description

The objective of this proposal is to test the feasibility and efficacy of two targeted induction chemotherapies obtained by adding either Lenalidomide or Ibrutinib to a standard Rituximab-High Dose (HD) Methotrexate (MTX) based induction chemotherapy regimen. The R-MPV regimen is chosen as the backbone chemotherapy because of its wide use with robust reproducible results and a good and manageable toxicity profile

Conditions

• Lymphoma, Large B-Cell, Diffuse
• Central Nervous System Neoplasms, Primary

Interventions

Type	Name	Description
DRUG	Lenalidomide	Patients will receive 4 cycles of induction chemotherapy with R-MPV + Lenalidomide using the Maximum Tolerated Dose (MTD) of Lenalidomide and Ibrutinib as determined in the phase-Ib part of the study.
DRUG	Ibrutinib	Patients will receive 4 cycles of induction chemotherapy with R-MPV + Ibrutinib, using the Maximum Tolerated Dose (MTD) of Lenalidomide and Ibrutinib as determined in the phase-Ib part of the study.
