Cost effectiveness analysis

Cost utility analysis

Effectiveness data was taken from a phase III randomised trial.

Direct unit medical costs were collected from each country participating in the trial (from 2015).

Outcomes were presented overall survival (OS) and progression free survival (PFS). The outcomes were also presented as quality adjusted life years (QALYs). Preference values were taken from European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30). The scores were mapped onto the EQ-5D questionnaire from which utility values were derived. The values were taken from three sources; Kontodimopoulos 2009, Kim 2012 and McKenzie 2009. The QALY calculation based on the assumption that the patient on treatment is to live for 4 months.

Restricted mean overall survival (RMOS)

Incremental cost effectiveness ratio (ICER).
