Patients and methods: Patients with mCRC and progression during or within 3 months following their last standard chemotherapy regimen were randomised to receive the approved dose of regorafenib of 160 mg QD (arm A) or 120 mg QD (arm B) administered as 3 weeks of treatment followed by 1 week off, or 160 mg QD 1 week on/1 week off (arm C). The primary end-point was the percentage of patients with G3/G4 treatment-related adverse events (AEs) in each arm. Results: There were 299 patients randomly assigned to arm A (n = 101), arm B (n = 99), or arm C (n = 99); 297 initiated treatments (arm A n = 100, arm B n = 98, arm C n = 99: population for safety analyses). G3/4 treatment-related AEs occurred in 60%, 55%, and 54% of patients in arms A, B, and C, respectively. The most common G3/4 AEs were hypertension (19, 12, and 20 patients), fatigue (20, 14, and 15 patients), hypokalemia (11, 7, and 10 patients), and hand-foot skin reaction (8, 7, and 3 patients). Median overall survival was 7.4 (IQR 4.0-13.7) months in arm A, 8.6 (IQR 3.8-13.4) in arm B, and 7.1 (IQR 4.4-12.4) in arm C. Conclusions: The alternative regorafenib dosing schedules were feasible and safe in patients with mCRC who had been previously treated with standard therapy. There was a higher numerical improvement on the most clinically relevant AEs in the intermittent dosing arm, particularly during the relevant first two cycles. http://hdl.handle.net/11351/9556 Còlon - Càncer - Tractament Recte - Càncer - Tractament Proteïnes quinases - Inhibidors - Ús terapèutic Metàstasi DISEASES::Neoplasms::Neoplasms by Site::Digestive System Neoplasms::Gastrointestinal Neoplasms::Intestinal Neoplasms::Colorectal Neoplasms Other subheadings::Other subheadings::Other subheadings::/drug therapy CHEMICALS AND DRUGS::Chemical Actions and Uses::Pharmacologic Actions::Molecular Mechanisms of Pharmacological Action::Enzyme Inhibitors::Protein Kinase Inhibitors Other subheadings::Other subheadings::/therapeutic use ENFERMEDADES::neoplasias::neoplasias por localización::neoplasias del sistema digestivo::neoplasias gastrointestinales::neoplasias intestinales::neoplasias colorrectales Otros calificadores::Otros calificadores::Otros calificadores::/farmacoterapia COMPUESTOS QUÍMICOS Y DROGAS::acciones y usos químicos::acciones farmacológicas::mecanismos moleculares de acción farmacológica::inhibidores enzimáticos::inhibidores de proteínas cinasas Otros calificadores::Otros calificadores::/uso terapéutico A randomised phase 2 study comparing different dose approaches of induction treatment of regorafenib in previously treated metastatic colorectal cancer patients (REARRANGE trial)
