Summary

This trial will compare the effects of two different therapies, ASA vs. Rivaroxaban, in newly diagnosed or relapsed and refractory multiple myeloma patients treated with Len-Dex combination therapy.

Who is the study for?
Adults diagnosed with Multiple Myeloma starting Len-Dex therapy can join. They must have certain blood, liver, and kidney function levels and be able to consent. Excluded are those with recent major surgery or bleeding, uncontrolled diseases like diabetes or heart conditions, allergies to study drugs, on antiplatelet agents for specific reasons, or a life expectancy under 3 months.
What is being tested?
The trial compares Rivaroxaban (a blood thinner) versus ASA (Aspirin) in preventing blood clots in patients with Multiple Myeloma who are receiving Lenalidomide Dexamethasone treatment. It's a phase IV study where participants are randomly assigned to one of the two drugs.
What are the potential side effects?
Rivaroxaban may cause bleeding complications, digestive issues or allergic reactions. Aspirin could lead to stomach ulcers, increased bleeding risk especially if taken at high doses over long periods.
