Compare Lenalidomide and Subcutaneous Daratumumab vs Lenalidomide and Dexamethasone in Frail Subjects With Previously Untreated Multiple Myeloma Who Are Ineligible for High Dose Therapy

• Status: Recruiting
• Trial end date: 2027-10-01
• Target enrollment: 0
• Participant gender: All

Summary

This is a Phase 3, randomized (study drug assigned by chance), open-label (participants and researchers are aware about the treatment, participants are receiving), active-controlled (study in which the experimental treatment or procedure is compared to a standard treatment or procedure), parallel-group (each group of participants will be treated at the same time), and multicenter (when more than one hospital team work on a medical research study) study in participants with newly diagnosed multiple myeloma (a blood cancer of plasma cells) and who are not candidates for high dose chemotherapy (treatment of disease, usually cancer, by chemical agents) and autologous stem cell transplant (ASCT). The primary hypothesis of this study is that subcutaneous Daratumumab in combination with Lenalidomide will prolong progression-free survival and likely induce less toxicity as compared with Lenalidomide and dexamethasone, in elderly frail subjects with newly diagnosed Multiple myeloma who are ineligible for high dose chemotherapy and ASCT

Women participating in this study must be postmenopausal.

8. Each subject must sign an informed consent form (ICF) indicating that he or she understands the purpose of and procedures required for the study and are willing to participate in the study. Subject must be willing and able to adhere to the prohibitions and restrictions specified in this protocol, as referenced in the ICF.

9. Subjects affiliated with an appropriate social security system.

Exclusion Criteria:

1. Subject has a diagnosis of primary amyloidosis, monoclonal gammopathy of undetermined significance, or smoldering multiple myeloma.

2. Subject has a diagnosis of Waldenström's disease, or other conditions in which IgM M-protein is present in the absence of a clonal plasma cell infiltration with lytic bone lesions.

3. Subject has prior or current systemic therapy or SCT for multiple myeloma

4. Subject has a history of malignancy (other than multiple myeloma) within 5 years before the date of randomization

5. Subject has had radiation therapy within 14 days of randomization.

6. Subject has had plasmapheresis within 28 days of randomization.

7. Subject is exhibiting clinical signs of meningeal involvement of multiple myeloma.

8. Subject has known chronic obstructive pulmonary disease (COPD) (defined as a forced expiratory volume [FEV] in 1 second <60% of predicted normal), persistent asthma, or a history of asthma within the last 2 years (intermittent asthma is allowed).

9. Subject is known to be seropositive for history of human immunodeficiency virus (HIV)

10. Seropositive for hepatitis B.

11. (Known to be) seropositive for hepatitis C

12. Subject has any concurrent medical or psychiatric condition or disease that is likely to interfere with the study procedures or results, or that in the opinion of the investigator, would constitute a hazard for participating in this study.

16. Subject is known or suspected of not being able to comply with the study protocol. Subject has any condition for which, in the opinion of the investigator, participation would not be in the best interest of the subject or that could prevent, limit, or confound the protocol-specified assessments.

17. Subject has had major surgery within 2 weeks before randomization or has not fully recovered from surgery.

18. Subject has received an investigational drug (including investigational vaccines) or used an invasive investigational medical device within 4 weeks before randomization or is currently enrolled in an interventional investigational study.

19. Refusal to consent or protected by legal regime ( guardianship, trusteeship)
