General information about the trial
|
|||
Main objective of the trial |
To determine the safety and tolerability of elotuzumab, thalidomide, and dexamethasone (E-Td) in subjects with relapsed and/or refractory multiple myeloma (MM) as assessed by the incidence of severe (Grade 3 or higher) non-hematological adverse events (AEs).
|
||
Protection of trial subjects |
The study was in compliance with the ethical principles derived from the Declaration of Helsinki and in compliance with all International Conference on Harmonization Good Clinical Practice Guidelines. All the local regulatory requirements pertinent to safety of trial subjects were followed.

Arm description |
Participants received thalidomide in 28-day cycles: 50 mg, for the first 2 weeks, escalated to 100 mg for the next 2 weeks and beginning with Cycle 2, to 200 mg once daily. Elotuzumab, 10 mg/kg, was administered as an intravenous infusion weekly for the first 2 cycles and beginning with Cycle 3, every 2 weeks. Dexamethasone, 40 mg, was administered weekly on those weeks when elotuzumab was not administered. On weeks when elotuzumab was also given, participants received dexamethasone as a split dose of 28 mg, 3 to 24 hours before the elotuzumab infusion, and 8 mg intravenously at least 45 minutes before the infusion. Those patients with suboptimal response, defined as evidence of progressive disease between end of Cycle 2 and end of Cycle 4 or inability to achieve partial response or better by end of Cycle 4, also received cyclophosphamide, 50 mg. Cyclophosphamide could not be added beyond Cycle 5. | ||||||||||||||||||||||
