What this trial studies

This clinical trial evaluates the effectiveness of Cecebot, a conversational agent, in improving insomnia among survivors of stage I-III breast cancer. Participants are randomized into two groups: one receiving immediate access to sleep education and activity tracking, and the other serving as a waitlist control. The intervention combines cognitive behavioral therapy for insomnia (CBTi) and physical activity strategies delivered via SMS over a 12-week period. The goal is to enhance sleep quality and overall quality of life for breast cancer survivors experiencing insomnia.

Who should consider this trial

Good fit: Ideal candidates for this study are female breast cancer survivors aged 18 and older who have clinically significant insomnia symptoms.

Not a fit: Patients with sleep disorders such as sleep apnea or those currently undergoing chemotherapy or radiation may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly improve sleep quality and quality of life for breast cancer survivors suffering from insomnia.

How similar studies have performed: Other studies have shown positive outcomes with similar CBTi approaches, suggesting potential for success in this novel application.
