A Prospective Study Comparing DRd With VRd-lite in Elderly Newly Diagnosed Multiple Myeloma

Официальное название

A Prospective, Multi-center, Open-label, Cohort Study to Compare Daratumumab-Lenalidomide-Dexamethasone (DRd) With Modified Bortezomib-Lenalidomide-Dexamethasone (VRd-lite) in Elderly Newly Diagnosed Multiple Myeloma

Обзор

The purpose of the study is to compare the efficacy and safety of daratumumab, lenalidomide and dexamethasone (DRd) to that of modified bortezomib, lenalidomide and dexamethasone (VRd-lite), in terms of progression-free survival and minimal residual disease negativity rate in elderly participants with newly diagnosed multiple myeloma.

Подробное описание

This is a prospective, open-label, multicentered cohort study. This study will evaluate elderly participants with newly diagnosed multiple myeloma (MM) for whom hematopoietic stem cell transplant is not planned as initial therapy. All the eligible participants can be free to choose to receive either daratumumab lenalidomide and dexamethasone (DRd) or modified bortezomib lenalidomide and dexamethasone (VRd-lite). Daratumumab (16 milligram per kilogram \[mg/kg\]) will be administered weekly for first 8 weeks (Cycles 1 to 2) of treatment and then every other week for 16 weeks (Cycles 3 to 6), then every 4 weeks (Cycle 7 to 8). Bortezomib will be administered subcutaneously 1.3 mg/m\^2 weekly of each 28-day cycle for Cycles 1-8. Lenalidomide will be administered at a dose of 25 mg orally on Days 1 through 21 of each 28-day cycle, and dexamethasone will be administered at a dose of 20 mg twice a week for both treatment arms. Participants in both treatment arms will continue at least lenalidomide maintenance until disease progression or unacceptable toxicity.The primary endpoint will be progression-free survival (PFS) and percentage of participants with Negative Minimal Residual Disease (MRD). Participant safety will be assessed throughout the study.

• Overall Survival (OS) [Срок оценки: From enrollment until the participant's death from any cause (up to approximately 5 years, or 8 years if the adaptive approach is decided at the interim)]
• Complete Response (CR) or Better Rate [Срок оценки: Approximately 5 years]
