OBJECTIVE: To compare healthcare resource utilization (HRU) between patients with metastatic melanoma (MM) initiated on first-line (1L) combination therapy with the BRAF inhibitor dabrafenib and the MEK inhibitor trametinib (D + T; oral) and those initiated on 1 L monotherapy with the anti-PD1 monoclonal antibodies nivolumab or pembrolizumab (N/P; intravenous). METHODS: Patients with melanoma initiated on D + T or N/P from Q1/2014 to Q2/2016 (defined as 1 L treatment for MM) were identified in the Truven MarketScan database. Entropy balancing was used to reweight the N/P cohort in order to make it comparable to the D + T cohort with respect to the mean and variance of baseline covariates. HRU outcomes during 1 L therapy, reported per patient-year (PPY), were described and compared between the two cohorts post-weighting (i.e. independently of baseline covariates). RESULTS: Of the 445 patients included, 202 and 243 were initiated on D + T and N/P, respectively. After weighting, patients initiated on N/P had more outpatient visits for drug administration during 1 L therapy than those initiated on D + T (difference = 18.6 visits PPY [95% CI = 16.0-21.1]). Patients initiated on N/P also had more outpatient office visits for reasons other than drug administration (difference = 8.1 visits PPY [95% CI = 1.9-13.7]). No significant differences were observed for other HRU parameters (i.e. inpatient admissions, inpatient days, and emergency department visits during 1 L therapy). CONCLUSIONS: HRU during 1 L therapy was generally similar between patients initiated on D + T and N/P. Nonetheless, patients initiated on N/P had more outpatient visits, including more outpatient visits for reasons unrelated to drug administration.
