简要总结

This is a multicenter, open label clinical trial evaluating the safety of the combination of belantamab mafodotin + the combination treatment VRd (bortezomib, lenalidomide, dexamethasone) in newly diagnosed (ND) transplant eligible multiple myeloma (MM) patients.

Eligible patients will be included in the study and they will receive three induction cycles with belantamab mafodotin (8-week cycles) and six induction cycles with VRd (4-week cycles). Immediately after the fourth VRd cycle, and in the absence of progression or unacceptable toxicity, mobilization of hematopoietic stem cells with G-CSF and subsequent apheresis will take place. Then, patients will receive one additional induction cycle with belantamab mafodotin (8-week cycle) and two additional induction cycles with VRd (4-week cycles) followed by intensification with high-dose melphalan (200mg/m2) and the autologous stem cell transplant. Three months after transplantation, and as long as clinical and hematological conditions allow, patients will receive one cycle of consolidation with belantamab mafodotin (8-week cycle) and two additional cycles of consolidation with VRd (4-week cycles) at the same doses as during induction and, subsequently, patients will receive maintenance treatment with lenalidomide (continuously until disease progression, patient withdrawal, unacceptable toxicity, loss to follow up, end of study or death) and belantamab mafodotin (for 2 years).

详细描述

The study comprise the following phases:

Induction: Cycles 1-6

Cycles will be of 8 weeks of duration for belantamab mafodotin and 28 days of duration for VRd:

Belantamab mafodotin will be administered at the dose of 2.5 mg/kg/every 8 weeks on day 1, intravenously.
Bortezomib will be given subcutaneously, at 1.3 mg/m2, on days: 1, 4, 8 and 11 of every 28-day cycle.
Lenalidomide will be given as an oral drug, in the dose of 25 mg/day on days 1-21.
Dexamethasone will be given as an oral drug, in the dose of 20 mg on days: 1, 2, 4, 5, 8, 9, 11 and 12.

Additional requirements for pregnancy testing during and after study intervention The investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with a nearly undetected pregnancy.
