20Background: The economic burden of MPC is substantial while treatment options are limited. This study compared treatment, supportive care, and total health care costs in MPC pts who initiated nab-P+G or FFX in a large insured US population. Methods: A retrospective study was conducted using claims from the Clinformatics Data Mart Database. Adults who had ≥2 claims for PC, ≥1 claim with a secondary malignancy, completed >1 cycle of nab-P+G or FFX as 1L between 1/1/2013 and 12/31/2015, and had continuous enrollment in health plans for ≥6 months prior to and 3 months following the start of 1L, were selected. Total health care costs and MPC-related treatment costs were measured per patient per month (PPPM) during 1L. Results: 216 MPC pts met selection criteria (nab-P+G, n=139; FFX, n=77). Pts on nab-P+G were significantly older (mean age: 67.6 vs. 61.4 years; p<0.001) vs. FFX. nab-P+G pts incurred similar total health care costs but less supportive care and treatment administration costs vs. FFX (table).
