Covalent BTK inhibitors have transformed the care of B-cell cancers such as CLL/SLL and MCL, but challenges to optimal care remain. How well do you understand the barriers to consistent, efficacious treatment with BTK-based treatment and what that means for treatment planning across multiple lines of therapy? During this activity, experts will tackle these questions and demonstrate how to strategically plan for and implement management protocols that address clinical problems such as BTK inhibitor resistance and intolerance. Throughout, the panelists will share insights on evidence-based and effective sequential therapy (including with second-generation covalent BTK inhibitors, noncovalent BTK options, and non–BTK inhibitor agent classes) and use case-based discussion to illustrate how therapeutic challenges associated with BTK inhibitor therapy can be overcome. Upon completion of this CE activity, participants will be able to: Develop plans to capture therapeutic intolerance or BTK resistance mutations before or at disease progression in patients receiving treatment with covalent BTK inhibitors, Select evidence-based sequential therapy for patients with CLL/SLL or MCL who are progressing on a covalent BTK inhibitor with resistance mutations, Recommend appropriate sequential options for patients with B-cell cancers who exhibit therapeutic intolerance to BTK inhibitors in order to maximize safety, ensure continued efficacy, and augment patient quality of life.
