Background: There is a need for a screening methodology to evaluate cost effectiveness of anticancer drugs. High costs raise concerns on approval, affordability and utilization. Objectives: Develop simplified methodology to screen and score cost versus value survival of docetaxel, cabazitaxel, abiraterone and sipuleucel-T in castrate- resistant prostate cancer (CRPC) Methods: Estimated costs in US $ of the entire course of an evaluated drug were added to downstream ancillary costs. The total was divided by the reported median survival gain over control in days. A reference value scale between 0- 100% was constructed with 0% assigned to cost/overall survival (OS) > $750, life threatening/ fatal adverse events (AEs) and worsened quality of life (QoL). A plan was designed to correct for AEs and QoL. Results were expressed as cost/OS and value and corrected scores. Results: Abiraterone at $5,000 per month x 6 months demonstrated cost/OS of $256 with 66% value and 61% corrected scores. Abiraterone x 9-12 months raised cost/OS and decreased scores. Generic docetaxel x 8 cycles demonstrated $63 cost/OS and 92% value score. Ancillary treatment increased cost/OS to $136 and decreased score to 82%. Cost/OS of cabazitaxel x 6 cycles ranged from $477- $596 with 21-36% scores. Corrections for AEs and QoL reduced scores to 6-21%. Sipuleucel-T demonstrated relatively higher cost/OS and lower scores. Conclusions: Preliminary findings would support utilization of docetaxel and abiraterone more than cabazitaxel and sipuleucel-T. The proposed methodology of cost versus value-survival could facilitate cost evaluation and budgetary planning of anticancer drugs.
