Original article Patterns of total cost and economic consequences of progression for patients with newly diagnosed multiple myeloma

Background: Few studies have addressed the cost patterns of patients with multiple myeloma (MM) before and after first relapse. This US claims analysis evaluated, from a US health plan perspective, patterns of total direct costs of care from treatment initiation to progression for patients with MM treated with novel agents, using time to next therapy (TTNT) as a proxy measure for progression. Methods: A retrospective study was conducted using a large US claims database, evaluating patients with claims for MM between 2006 and 2013. Patients with claims for stem cell transplant (SCT) were excluded. The analysis focused on patients receiving lenalidomide (LEN) or bortezomib (BORT) based treatment, for whom complete claim history was available through initiation of subsequent treatment. Average patient monthly direct costs were determined, including medical and pharmacy costs, and total cost patterns over quarterly time periods were calculated.
