Managing CDK4/6 Inhibitor Toxicities and Encouraging Adherence

Panelists discuss how common adverse events (AEs) with CDK4/6 inhibitors in HR+/HER2- early breast cancer (eBC) vary based on treatment and patient population, with strategies for mitigating toxicities, adjusting dosing, and monitoring labs to ensure treatment continuation; they also address approaches to dose reductions, promoting treatment adherence, educating patients about toxicity management, and balancing efficacy, quality of life, and side effect risks, particularly for high-risk patients with no or low nodal involvement.

Video content above is prompted by the following:

  1. What adverse events (AEs) do you commonly see in your practice with CDK4/6 inhibitors?
    1. In your experience, how can these vary based on the treatment and patient population?
    2. What strategies work best for you to mitigate these toxicities?
    3. What dosing adjustments or lab monitoring can help manage toxicity for treatment continuation?
  2. What is your approach to dose reductions or interruptions with CDK4/6 inhibitors when managing AEs? What is your threshold for dose reductions?
    1. How important is treatment adherence and continuation for maintaining the efficacy benefits?
    2. What strategies might promote adherence?
  3. Could you walk through your approach to educating patients about potential CDK4/6 inhibitor toxicity?
    1. How do you counsel patients on symptom reporting?
  4. How do you balance efficacy, quality of life, and adverse effect risks when selecting systemic therapy for patients with eBC?
    1. Does this balance shift for high-risk patients with no or low nodal involvement?
