Summary
Due to economic reasons, thalidomide is still widely used as a first line drug for Multiple Myeloma patients in China. However,the efficacy of CTd is still lower than the therapeutic regimens with new drugs. Clarithromycin may have partly efficacy in association with steroids and thalidomide for Multiple Myeloma patients. This multicenter, randomized, phase 3 clinical trial is proposed to explore whether clarithromycin could potentiate responsiveness of CTd (Cyclophosphamide, Thalidomide and Dexamethasone) regimen in Newly Diagnosed Multiple Myeloma patients. The trial will also evaluate the side effects caused by the combination of these drugs.
Detailed Description
This phase III,randomized controlled trial will enroll 130(65 each arm) newly diagnosed patients with active disease from 4 medical centers in East China.

The participants are randomly equally selected to receive BiCTd regimen arm or CTd regimen arm. The treatment consists of eight induction and consolidation therapy followed by maintenance therapy.

BiCTd(Clarithromycin, Cyclophosphamide, Thalidomide and Dexamethasone) regimen arm: Induction and consolidation Phase: All patients will also receive aspirin 100mg PO QD while receiving BiCTd. Aspirin will continue through maintenance.

Clarithromycin 500 mg orally daily on days 1-28,thalidomide 100-200mg orally on days d1-28, dexamethasone 40 mg orally on days on 1,8,15,22, and cyclophosphamide 300 mg/m^2 intravenously on day 1-3. Eight Cycles were repeated every 28 days.

If efficacy
Maintenance Therapy:

Patients who complete the induction and consolidation regimen could be started on maintenance therapy as follows: Maintenance with CP (cyclophosphamide 200 mg orally on days 1-14 and prednisone 30mg twice daily orally on days 1-7,repeated every 28 days) regimen until disease progression.

CTd regimen arm: Induction and consolidation Phase: All patients will also receive aspirin 100mg PO QD while receiving CTd. Aspirin will continue through maintenance.

Thalidomide 100-200mg orally on days d1-28, dexamethasone 40 mg orally on days on 1,8,15,22, and cyclophosphamide 300 mg/m^2 intravenously on day 1-3. Eight Cycles were repeated every 28 days.

If efficacy
If no further reduction in the serum and urine M protein in the next cycle,patients may cross over to BiCTd regimen.

Maintenance Therapy:

Patients who complete the induction and consolidation regimen could be started on maintenance therapy as follows: Maintenance with CP (cyclophosphamide 200 mg orally on days 1-14 and prednisone 30mg twice daily orally on days 1-7,repeated every 28 days) regimen until disease progression Then, patients will be followed up for 24 months after chemotherapy. The investigators will record all the laboratory and clinical investigations to assess response at different points of the study. We also assess adverse events (AEs), as graded according to NCI-Common Toxicity Criteria for Adverse Effects (CTCAE) Version 4.0.Response categories were based on the International Myeloma Working Group uniform response criteria.
