Effect of High-Fat Food on the Pharmacokinetic Profile and Safety of SAF-189s, an ALK/ROS1 Inhibitor, in Healthy Chinese Adults

This study was conducted to investigate the effect of high-fat meals on the pharmacokinetics (PK) and safety profile of SAF-189s, a novel ALK/ROS1 inhibitor. This was a single-center, phase I, open-label, crossover study in which healthy adults (≥18 years) were randomized (1:1) to two sequences of SAF-189s administration (fasted-fed or fed-fasted) separated by a 14-day washout. After a ≥10-h overnight fast, volunteers received SAF-189s 160 mg orally in a fasted state or 30 min after a high-fat, high-calorie meal. Similarity of pharmacokinetic parameters was concluded if the 90
