Study Comparing Lenalidomide and Dexamethasone With or Without Daratumumab for High-Risk Smoldering Myeloma

What this Trial Is About

Researchers are evaluating the effects of lenalidomide and dexamethasone with or without daratumumab in treating patients with high-risk smoldering multiple myeloma. This phase III trial aims to compare overall survival, progression-free survival, response rates, and safety between these treatments. The study also explores patient-reported quality of life, treatment adherence, minimal residual disease status, and imaging associations during therapy. Participants are randomly assigned to one of two treatment groups. The first group receives daratumumab intravenously on a detailed schedule across up to 24 courses, plus oral lenalidomide daily for 21 days and dexamethasone on specific days during the first 12 courses. The second group receives only oral lenalidomide and dexamethasone on a similar schedule for up to 24 courses. Treatment cycles repeat every 28 days unless disease progression or unacceptable side effects occur. During the study, participants complete quality-of-life questionnaires and undergo laboratory tests, including minimal residual disease assessments and PETCT imaging. Safety is closely monitored, especially infusion-related reactions and toxicity. After treatment, patients are followed for up to 15 years with periodic visits every 3 to 12 months to track long-term outcomes and survival.
