Cost Of Care For Patients With Metastatic Castration-Resistant Prostate Cancer Initiating On Docetaxel Versus Oral Targeted Therapies In The United States.

88Background: Abiraterone acetate + prednisone and enzalutamide are approved oral targeted therapies (OTT) for metastatic castration-resistant prostate cancer (mCRPC) which have significant clinical benefit. However, their impact on healthcare cost relative to docetaxel (DOC) is not well understood. Methods: This retrospective cohort study used combined claims data from Truven MarketScan Commercial and Medicare Supplement Plan databases. Males ≥18 years with ≥1 prostate cancer diagnosis and a subsequent metastasis diagnosis were indexed on the first claim date of DOC or OTT between 1/1/2012 and 12/31/2016. ≥1 claim for an androgen deprivation therapy during the 12-month continuous enrollment period prior to metastasis was required; patients with end stage renal disease or other primary cancer were excluded. All-cause per patient per year (PPPY) costs were estimated in 2016 US dollars. A generalized linear model was used to compare adjusted costs between DOC and OTT cohorts. Results: A total of 1,159 and 2...
