Descriptive Information

• Brief Title: Phase 1 Study of DS-6051b in Japanese Subjects With Advanced Solid Malignant Tumors
• Official Title: Phase 1 Study of DS-6051b in Japanese Subjects With Advanced Solid Malignant Tumors Harboring Either a ROS1 or NTRK Fusion Gene
• Brief Summary: This is a Phase 1 study to evaluate the safety, tolerability, and pharmacokinetics of DS-6051b in Japanese subjects with advanced solid malignant tumors harboring either a ROS1 or NTRK fusion gene.
• Detailed Description: This study is single arm study with DS-6051b in approximately 9 subjects with advanced solid malignant tumors harboring either a ROS1 or NTRK fusion gene. Safety and tolerability, pharmacokinetics (PK), maximum tolerated dose/recommended phase 2 dose (MTD/RP2D) and preliminary efficacy of DS-6051b will be evaluated.
