What this Trial Is About

This study adopts a single-center, open-label, non-randomized trial design. It plans to enroll patients with HR- positive, HER2- negative advanced breast cancer who are resistant to (neo)adjuvant endocrine therapy. Dose-escalation and dose-expansion studies will be carried out to evaluate the safety, tolerability, and preliminary efficacy of sirolimus (albumin-bound) in combination with palbociclib and fulvestrant in this patient population, and to confirm the recommended phase 2 dose (RP2D)
