Phase 2
Conditions
patients with HR-positive and HER2-negative advanced breast cancer
HR-positive and HER2-negative advanced breast cancer

Lead Sponsor

Brief Summary

Although the incidence of diarrhea did not improve in both arms compared to historical data, bifidobacterial with or without TM shortened the duration of AID and prevented grade 3 or higher diarrhea, while the rate of constipation unchanged. As a result, the incidences of drug suspension/reduction were decreased.
