Spots Global Cancer Trial Database for GEM-CLARIDEX: Ld vs BiRd

Study Description

Brief Summary: This phase III study, open-label, randomized study investigating lenalidomide and dexamethasone with and without biaxin in subjects with newly diagnosed, previously untreated MM. Eligible subjects will be randomized in a 1:1 ratio to receive a regimen consisting of either biaxin, lenalidomide, and low-dose dexamethasone (BiRd arm), or lenalidomide and low-dose dexamethasone (Rd arm). 306 patients will be included (50% in Spain (153) and 50% in the USA (153)

Detailed Description: BiRd Arm Subjects on the BiRD arm will receive clarithromycin, Revlimid (lenalidomide), and dexamethasone in 28-day cycles. Dosing is as follows: * Clarithromycin 500mg PO twice daily on days 1-28 for a 28-day cycle. If a dose of clarithromycin is missed, it should be taken as soon as possible on the same day. If it is missed for the entire day, it should not be made up. Vomited doses will not be made up. * Lenalidomide 25mg PO daily on days 1-21 of a 28-day cycle for patients with a calculated creatinine clearance of \>60 cc/min. Patients with a calculated creatinine clearance of \<60 cc/min will receive 15 mgs PO daily on days 1-21 of a 28 cycle. If a dose of lenalidomide is missed, it should be taken as soon as possible on the same day. If it is missed for the entire day, it should not be made up. Vomited doses will not be made up. * Dexamethasone 40mg PO will be given on days 1, 8, 15, 22 of a 28-day cycle. Missed or vomited doses will not be made up. If subject cannot tolerate oral dexamethasone, it will be given intravenously. Rd Arm Subjects on the Rd arm will receive Revlimid, and dexamethasone in 28-day cycles. Dosing is as follows: * Lenalidomide 25mg PO daily on days 1-21 of a 28-day cycle for patients with a calculated creatinine clearance of \>60 cc/min. Patients with a calculated clearance of \<60 cc/min will receive 15 mgs PO daily on days 1-21 of a28 cycle. If a dose of lenalidomide is missed, it should be taken as soon as possible on the same day. If it is missed for the entire day, it should not be made up. Vomited doses will not be made up. * Dexamethasone 40mg PO will be given on days 1, 8, 15, 22 of a 28-day cycle. Missed or vomited doses will not be made up. If subject cannot tolerate oral dexamethasone, it will be given intravenously. Correlative studies: Relative dose intensity: Projected total dose per cycle of each component of assigned drug will be divided by the actual dose received and a ratio will be assessed for each cycle delivered. MRD: Minimal residual disease testing will be performed in subjects who achieve complete response. MRD testing may be performed either by flow cytometry or polymerase chain reaction (PCR), whichever is more readily available at the study institution. Subjects will continue their randomized treatment assignment until disease progression or unacceptable toxicity (whichever occurs first). In case toxicity precludes dosing of one agent (i.e dexamethasone, clarithromycin, lenalidomide), treatment regimen will continue with the remaining agents. Subjects unable to receive ALL the components of the assigned treatment arms will be removed from study after reasonable attempts to dose reduce and manage side effects. Subjects can also be removed from study at investigator's discretion, or if they withdraw consent. At completion or early discontinuation of treatment, subjects will be followed for 30 additional days or up to the initiation of subsequent treatment (whichever occurs first), after which they will be off the active treatment phase of the study. Long-term follow-up for disease status and survival will proceed until the subject has withdrawn consent, is lost to follow-up, or has died.
