Abstract 5263

Background

Part 1 of the COLUMBUS study demonstrated that the BRAF inhibitor ENCO 450 mg once daily (QD) + the MEK inhibitor BINI 45 mg twice daily (BID; COMBO450) improved progression-free survival vs VEM 960 mg BID alone and ENCO 300 mg QD (ENCO300) alone in patients (pts) with advanced BRAF V600−mutant melanoma. Tolerability of COMBO450 was favorable compared with VEM or ENCO300. Here we evaluate resource utilization based on hospitalization data (ClinicalTrials.gov, NCT01909453; EudraCT, 2013-001176-38).

Methods

Pts were randomized 1:1:1 to receive COMBO450, VEM, or ENCO300. Efficacy endpoints, including the number of pts hospitalized and number of hospitalizations, were described. Time to first occurrence of hospitalization was assessed by the Kaplan-Meier method. Hospitalization endpoints were adjusted per 100 pt-months (pt-mo) of exposure to study drug.

Results

Among 577 pts, 192 were randomized to COMBO450, 191 were randomized to VEM, and 194 were randomized ENCO300. Exposure-adjusted hospitalization rates (per 100 pt-mo) were 3.5% in the COMBO450 arm compared with 4.3% and 6.2% in the ENCO300 and VEM arms, respectively. Exposure-adjusted mean duration of hospitalization per 100 pt-mo was 32.5, 38.2, and 53.7 days in the COMBO450, ENCO300, and VEM arms, respectively. Median (95% CI) time to first hospitalization for pts with ≥1 event was 5.1 (2.6–6.1) mo in the COMBO450 arm compared with 2.8 (0.8–4.2) and 2.8 (2.0–3.8) mo in the ENCO300 and VEM arms, respectively.

Conclusions

Resource utilization, as determined by hospitalization data in COLUMBUS Part 1, was lower with COMBO450 compared with VEM or ENCO300 monotherapy.
