ObjectivesOral oncolytics are an increasingly important treatment option for cancer. These agents often fall within the pharmacy benefit, with the potential for increased out-of-pocket (OOP) cost burden for patients. The purpose of this study was to evaluate patient OOP payments for oral oncolytic therapies in US managed care plans.Materials And MethodsPatients aged >18 years who received 1 of 21 oral oncolytics were identified in 2009 US claims; the first oral therapy was the index therapy. OOP payments were calculated as the allowed amount (dollar amount a health plan allows for a therapy, including member liability) minus the paid amount (dollar amount paid by a health plan). Patient characteristics were provided, and per-claim OOP payments were evaluated for each of the 21 therapies in aggregate and stratified by payer type and index therapy.ResultsA total of 6094 patients who received at least 1 oral oncolytic therapy were identified. Mean age was 53 years; 54% were women; 77% had a commercial payer; prevalent cancer diagnoses included breast, colorectal, glioblastoma, and lung. Mean OOP payments were highest for dasatinib ($527; median, $36) and lowest for cyclophosphamide ($15; median, $10). Medicare Risk patients had higher mean OOP payments for most therapies compared with commercial, Medicaid, and self-insured patients.ConclusionsAmong 21 oral oncolytics, average OOP cost ranged from $15 to >$500. These results confirm previous findings showing OOP payments differing widely among oral oncolytic options. As cost for therapy becomes a greater part of treatment decisions, an understanding of patient OOP cost will be critical in informing choices.
