Abstract
Background
Many pts with aGOAC are elderly and/or frail. GO2 [ASCO 2019 #4006] found that lower dose OxaliplatinCapecitabine (OCap) led to non-inferior progression free survival, less toxicity and better patient-centred outcomes using a novel composite endpoint ‘Overall Treatment Utility’. QoL endpoints were chosen to reflect the balance between benefits and harms of the three dose levels and to help patients understand likely implications of treatment for shared decision making.
Methods
Eligible pts unsuitable for full-dose 3-drug chemotherapy due to frailty, but fit for OCap. Baseline assessment included QoL; symptoms; functional scales; comorbidity; frailty. Randomization was 1:1:1 to dose Level (Lvl) A (Ox 130 mg/m2d1, Cap 625 mg/m2bd d1-21, q21d), B (80% Lvl A doses) or C (60% Lvl A doses) until progression or decision to stop. An alternative randomisation option where chemo benefit was considered uncertain (‘uc’) was between OCap Lvl C and Best Supportive Care (BSC). QoL (EQ-VAS) was measured weekly during chemotherapy. QoL (EQ-5D), Fatigue (EORTC QLQ-C30 Fatigue scale) were measured 9-weekly for 1 year. QoL endpoints were analysed descriptively as pre-defined in the statistical analysis plan.
Results
558 pts were enrolled, 2014-17, 61 UK centres, of which 45 pts were in the uc randomisation.
