Impact of treatment suspension on health-related quality of life in the EMBARK trial: a post hoc analysis.

ABSTRACT:

Background

Enzalutamide was approved for high-risk biochemically recurrent (hrBCR) prostate cancer based on the EMBARK trial (NCT02319837; 17 December 2014-31 January 2023). In EMBARK, treatment was suspended at week 37 if prostate-specific antigen (PSA) was <0.2 ng/mL and reinstated if PSA rose to ≥2.0 ng/mL with radical prostatectomy or ≥5.0 ng/mL without. This post hoc analysis assessed the impact of treatment suspension on health-related quality of life (HRQoL) to address overtreatment concerns.

Methods

Longitudinal change in HRQoL from treatment suspension at week 37 to subsequent assessments until week 109 was analyzed with mixed models for repeated measures (MMRM) and descriptively among these patients. Separate models were used to assess four patient-reported outcome
