Résumé

AIM: The feasibility of an alternating regimen of BIBF 1120, a potent, oral, triple angiokinase inhibitor, and afatinib (BIBW 2992), a potent ErbB family blocker, was explored in patients with advanced pretreated colorectal cancer (CRC). PATIENTS AND METHODS: Patients received repeated courses of alternating 7-day treatment periods, first with BIBF 1120 250 mg twice daily and then afatinib 50 mg once daily. The primary endpoint was the objective response rate; the incidence/severity of adverse events (AEs) and pharmacokinetics (PK) were determined. RESULTS: Forty-six patients (>/=4 prior lines, most anti-VEGF and/or -EGFR pretreated) received BIBF 1120 and afatinib. No objective responses were observed; the best response was stable disease in 20 patients (43.5%). Seven patients (15.2%) remained progression-free for >/=16 weeks. Median progression-free survival was 1.9 months; median overall survival was 5.5 months. The most frequent drug-related AEs were diarrhoea (80.4%), asthenia (47.8%), nausea (43.5%) and rash (41.3%). PK assessments did not show obvious alterations for either drug. CONCLUSION: Weekly alternating administration of BIBF 1120 and afatinib is feasible; however, its efficacy was limited in this highly palliative patient population.
