Spots Global Cancer Trial Database for Rivaroxaban or Aspirin As Thromboprophylaxis in Multiple Myeloma

Study Description

Brief Summary: The intended study is designed as a a phase IV pragmatic multicenter randomized controlled clinical trial, comparing the impact of two different therapies including ASA vs. Rivaroxaban in newly diagnosed or relapsed and refractory multiple myeloma patients treated with Lenalidomide Dexamethasone (Len-Dex) combination therapy. The pilot feasibility study was conducted in preparation for this randomized controlled trial designed to assess the effect of an intervention.

Detailed Description: RithMM is a phase IV, pragmatic, multicenter, open label Canadian trial. The study started with a pilot feasibility phase where 3 centres (London, Ottawa and Halifax) enrolled 34 patients within 12 months. Utilizing a roll-over design, the full RithMM trial will require a total of 304 patients to demonstrate that rivaroxaban 10 mg daily for 6 months is superior to ASA 81 mg daily for 6 months in preventing any thromboembolic events in newly diagnosed myeloma (NDMM) and relapsed/refractory (RRMM) patients on Len-Dex -based therapy. The study will require 8 participating centres in order to be able to achieve our recruitment goal within 12 to 18 months. Patients with NDMM or RRMM receiving Len-Dex based combination therapy with or without combination with other anti-myeloma drugs will be assessed for eligibility to be enrolled in the study. The research team intends to rollover the participants of our feasibility study into this current full randomized control trial comparing the efficacy outcome for the RithMM trial is the overall incidence of cardiovascular events, which includes arterial or venous thromboembolic events. By conducting this trial, the investigators plan to externally validate the International Myeloma Working Group (IMWG) criteria model for thromboembolic risk by assessing the relevance of measuring pre-specified myeloma and thrombosis activity biomarkers (D-Dimer, beta-2 microglobulin, C-reactive protein (CRP), LDH) at every follow-up visit and their potential association with thromboembolism (TE) risk.
