A Trial in Healthy Participants to Assess Drug Interaction Potential of BGB-43395

BGB-43395 is a drug that blocks a protein called cyclin-dependent kinase 4 (CDK4). CDK4 is a type of protein that regulates cell growth and division and can drive uncontrolled tumor cell growth. BGB-43395 is being developed for the treatment of patients with advanced solid tumors. The purpose of this study is to test whether BGB-43395 has any significant drug interactions with midazolam, celecoxib, dabigatran, and rosuvastatin. The main goal of the study is to test whether BGB-43395 affects how other drugs are processed by the body. This study consists of 2 parts. In Part 1, healthy participants will receive midazolam and celecoxib alone and with BGB-43395. In Part 2, healthy participants will receive dabigatran and rosuvastatin alone and with BGB-43395. The study will enroll approximately 24 healthy adult participants. The overall time to participate in this study is up to 7 weeks. Blood samples will be taken at specific time points, as well as vital signs and electrocardiograms.
