Uncovering mechanisms of resistance to CDK inhibition in breast cancer., Canada

Registration Status: Completed

Objective: We will obtain breast cancer tumor specimens from various subtypes of breast cancer from patients undergoing routine surgery as part of their standard of care. Tissue will primarily be used for ex vivo analyses in support of a study examining the efficacy of combination treatment with CDK4/6 and FAK inhibitors. The primary objectives of the study are: • Determine the basal activity of FAK in patient tumor tissue ex vivo and correlate it with response to CDK4/6 inhibitor treatment. • Determine the ability of the combination treatment with CDK4/6 and FAK inhibitors to more effectively inhibit tumor viability ex vivo than either drug alone. • Validate ex vivo findings of effective combination treatments in patient-derived xenograft preclinical animal models.

  • Mono: A biobank that supports a specific research project, may have few staff members, a small-scale accrual scope with little to no initial intention of releasing or distributing biospecimens to secondary parties
  • Oligo: A biobank that supports several research groups or clinical trials, may or may not be designed to release biospecimens outside their collaborative group
  • Poly: A biobank that has generally a larger accrual scope, resources, and multiple users outside the biobank proper
