SPOCK Trial Summary

This trial is testing if scientists can correctly predict which of several guideline-recommended treatments for metastatic, estrogen receptor-positive breast cancer is best for each patient, using the tumor's biology.

Who is the study for?
This trial is for adults with metastatic breast cancer that's positive for estrogen receptor and has worsened after treatment with aromatase inhibitors and CDK4/6 inhibitors. Participants need to have a tumor suitable for biopsy, be in fairly good health (ECOG 0-2), and not have received certain other treatments or have another life-threatening cancer.Check my eligibility
What is being tested?
The study aims to see if using the biology of tumors can predict which among several approved treatments would work best for individuals whose breast cancer has progressed on specific previous therapies. It also seeks to gather more information about these tumors to develop better future treatments.See study design
What are the potential side effects?
While the summary doesn't specify side effects, typical ones from such therapies may include fatigue, nausea, skin reactions, low blood counts leading to increased infection risk or bleeding problems, hormonal changes, and potential liver issues.
