- Claire Gallois (Paris, France)
Abstract
Background
The combination of encorafenib with cetuximab has become the standard of care in patients with
Methods
All consecutive patients with
Results
Overall, 201 patients were included, with 55% of women, a median age of 62 years and an ECOG-PS ≥2 in 20% of cases. Other main patients’ tumor characteristics were 60% of right-sided primary tumor, 11% of MSI/dMMR phenotype and liver and peritoneum being the 2 main metastatic sites (57% and 51%). The e/c+/-b combination was prescribed in 1st line (L1) for 8 patients (4%), in 2nd line (L2) for 113 patients (56%), in 3rd line (L3) for 58 patients (29%), beyond L3 for 22 patients (11.3% ), with an addition of binimetinib for 21 patients (10%). With e/c treatment, 21% of patients experienced grade ≥3 adverse events (AEs), with each type of grade ≥3 AE observed in less than 5% of patients The most frequent grade 1-2 AEs were acneiform dermatitis/rash (43%), dry skin (29%), arthralgia (21%), and anemia (22%). The objective response rate under e/c+/-b was 32% and the disease control rate was 71%, all lines combined. Median PFS under e/c+/-b was 4.4 months (95% CI 3.9-5.6) and median OS was 9.1 months (95% CI 7.8-10.8). In multivariate analysis, the factors associated with a shorter PFS under e/c+/-b were the presence of liver metastases (HR: 1.6, p=0.02) and ECOG-PS≥2 (HR: 1.9, p=0.002) but not the line of treatment.
