Official title
REVERT- Breast Cancer: Phase 1b/2 Study of the Addition of STAT3 Inhibitor TTI-101 to Reverse Resistance to Palbociclib or Ribociclib Plus Aromatase Inhibitor or Fulvestrant Therapy for Metastatic Hormone Receptor-Positive and HER2-Negative Breast Cancer
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The primary objective of Phase 1b will be to evaluate the safety and tolerability of TTI-101 when added to palbociclib and AI or fulvestrant administered orally to participants with hormone receptor-positive (HR+) human epidermal receptor 2-negative (HER2)- palbociclib-resistant breast cancer, and to determine the recommended Phase 2 dose (RP2D) for TTI-101 when added to palbociclib and AI or fulvestrant. The primary objective of Phase 2 will be to evaluate anti-tumor activity in participants who receive TTI-101 added to palbociclib or ribociclib and AI or fulvestrant.
