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 suggests progress, the low end shows sponsors still face many challenges in recruiting for breast cancer studies. These include overwhelmed patients, unclear communication, and difficulty finding 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.
