Citeline's Patient Recruitment Pulse — October 2026

Studies report breast cancer clinical trial participation rates ranging from 5% to 25%. While the high end of this range indicates some positive progress, the low end indicates there are still many challenges for sponsors looking to fill breast cancer studies. They include overwhelmed patients, unclear communication, and difficulty when seeking trusted information sources.

Sponsors need to address these challenges in a way that keeps the patient centered in the process. Some tactics include giving patients time to make the decision to participate, involving the treating physician in communications, and using social media to inform patients about clinical trials that are actively recruiting.
