Abstract 3925


D + T improved outcomes and HRQOL in pts with BRAF V600–mutant melanoma vs BRAFi alone in COMBI-d (NCT01584648) and COMBI-v (NCT01597908). Although pooled analysis of melanoma clinical/prognostic characteristics across D + T registration trials identified baseline (BL) LDH as the most influential covariate on outcomes, D + T improved response, PFS, and OS vs BRAFi alone in both normal and elevated-LDH groups. This retrospective analysis of COMBI-d and COMBI-v patient-reported outcomes (PROs) assessed whether HRQOL was consistently improved across LDH groups.


COMBI-d and COMBI-v are phase 3, randomized, double-blind studies of first-line D + T vs D + placebo (Pbo) or vemurafenib (V), respectively, in pts with unresectable stage IIIC or IV BRAF V600–mutant melanoma. HRQOL was evaluated in COMBI-d and COMBI-v by EORTC QLQ-C30 (global QOL, functional, and symptom domains) at BL, during treatment (Tx), and at disease progression (PD). PROs were analyzed by LDH (≤ and > ULN). ANCOVA adjusted for BL score using mixed-model repeated measures was carried out.


Across COMBI-d (D + T, n = 211 [77 with LDH > ULN]; D + Pbo, n = 212 [71 with LDH > ULN]) and COMBI-v (D + T, n = 352 [118 with LDH > ULN]; V, n = 352 [114 with LDH > ULN]), EORTC QLQ-C30 completion rates were > 85% through wk 40 and ≥ 70% at PD. Clinically meaningful differences in mean scores between arms favoring D + T vs BRAFi alone were seen for most HRQOL domains for both LDH subgroups across time points, including at PD (Table). Results for D + T vs BRAFi alone by LDH in COMBI-d and COMBI-v for all EORTC QLQ-C3cl be presented.

D + T consistently improved HRQOL vs BRAFi alone for most EORTC QLQ-C30 domains, regardless of LDH, further supporting continued use of D + T in BRAF-mutant melanoma across LDH subgroups. HRQOL benefit with D + T may be greater in pts with LDH > ULN.
