Clinical Trial Summary

The purpose of this study is to compare the effectiveness of daratumumab when combined with lenalidomide and dexamethasone (DRd) to that of lenalidomide and dexamethasone (Rd), in terms of progression-free survival in participants with relapsed or refractory multiple myeloma.

Description:

This is a randomized (participants will be assigned by chance to study treatments), open-label (all participants and study personnel will know the identity of the study treatments), active-controlled (none of the study treatments are placebo), parallel-group (both treatment arms will run at the same time), multicenter study. In this study, daratumumab, lenalidomide, and low-dose dexamethasone (DRd) will be compared with lenalidomide and low dose dexamethasone (Rd) in participants with relapsed or refractory multiple myeloma. Participants will be randomized in a 1:1 ratio to receive either DRd or Rd. The study will include a Screening Phase, a Treatment Phase (involving treatment cycles of approximately 28 days in length), and a Follow-up Phase. The Treatment Phase will extend from the administration of the first dose of study medication until disease progression or unacceptable toxicity. Participants will also discontinue study treatment if: they become pregnant; have their dose held for more than 28 days (or if 3 consecutive planned doses of daratumumab are missed for reasons other than toxicity); or for safety reasons (for example, adverse event). The Follow-up Phase will begin at the end of treatment and will continue until death, loss to follow-up, consent withdrawal for study participation, or the final overall survival (OS) analysis, whichever occurs first. Eligible participants from Rd group who have had sponsor confirmed disease progression will be offered the option for treatment with daratumumab monotherapy (of 28 days cycle). The primary endpoint will be progression-free survival (PFS). Analysis of the primary endpoint was performed at a pre-specified point determined by PFS events with a clinical cutoff of March 7, 2016 when 169 events of death or progression had occurred. The end of study is anticipated at approximately 6 years after the last participant is randomized. Blood and urine samples will be obtained at time points during the study, together with bone marrow aspirates/biopsies and skeletal surveys. Participant safety will be assessed throughout the study.

• Has received anti-myeloma treatment within 2 weeks or 5 pharmacokinetic half-lives of the treatment

• Has received autologous stem cell transplantation within 12 weeks before the date of randomization, or previously received an allogenic stem cell transplant (regardless of timing), or planning to undergo a stem cell transplant prior to progression of disease
• History of malignancy (other than multiple myeloma) within 5 years before the first dose of daratumumab monotherapy (exceptions are squamous and basal cell carcinomas of the skin and carcinoma in situ of the cervix, or breast, or other non-invasive lesion, that in the opinion of the investigator, with concurrence with the sponsor's medical monitor, is considered cured with minimal risk of recurrence within 5 years)

Related Conditions & MeSH terms

Intervention

Drug:
• Daratumumab
Daratumumab 16mg/kg will be administered as an intravenous (IV) infusion (into the vein) as per the following schedule: once a week during treatment cycles 1 and 2; every 2 weeks during treatment cycles 3 to 6; and every 4 weeks for cycles 7 and onwards. Following amendment 8, participants receiving daratumumab IV have the option to switch to daratumumab subcutaneous (SC) 1800 mg/dose until documented progression, unacceptable toxicity, or the end of study on Day 1 of any cycle, at the discretion of the investigator.
• Lenalidomide
Lenalidomide will be administered at a dose of 25 mg orally (by mouth) on Days 1 through 21 of each treatment cycle.
• Dexamethasone
Dexamethasone (or equivalent in accordance with local standards) will be administered as a total dose of 40 mg weekly (or 20 mg weekly for participants > 75 years old or with a body mass index < 18.5).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Progression-free Survival (PFS)	PFS: duration from date of randomization to either progressive disease (PD)/death, whichever occurred first. PD: defined as meeting any 1 of following criteria: Increase of greater than equal to (>=)25 percent(%) in level of serum M-protein from lowest response value and absolute increase must be >=0.5 gram per deciliter (g/dL); Increase of >=25% in 24-hours(h) urinary light chain excretion (urine M-protein) from lowest response value and absolute increase must be >=200 mg/24h; Only in participants without measurable serum and urine M-protein levels: increase of >=25% in difference between involved and uninvolved free light chain (FLC) levels from lowest response value and absolute increase must be >10 mg/dL; Definite increase in size of existing bone lesions or soft tissue plasmacytomas; Definite development of new bone lesions or soft tissue plasmacytomas; Development of hypercalcemia (corrected serum calcium >11.5 mg/dL) attributed solely to plasma cell (PC) proliferative disorder.
