Hypothesis #2: The 6-month rate of symptomatic VTE in MM patients receiving IMiDs who are prescribed apixaban 2.5 mg orally twice daily for primary prevention of VTE will be <7% (3). Although additional therapies for MM such as dexamethasone and erythropoietin-stimulating agents may further increase the risk of VTE, the rate of incident VTE should be reduced to <7% with apixaban.
