BEBT-209 capsules

Title: A Study to See if BEBT-209 Combined With Chemotherapy Works to Treat People With Triple-Negative Breast Cancer Researchers want to learn if a new drug called BEBT-209 works to treat people with a specific type of breast cancer. This cancer is called locally advanced or metastatic triple-negative breast cancer (TNBC). The study has two parts. In the first part, researchers want to see if the new drug combination can shrink tumors. In the second part, researchers want to see if this treatment helps people live longer. Researchers will put participants into two groups by chance. This is like flipping a coin. Group 1: Participants get BEBT-209 plus two chemotherapy drugs. These drugs are Carboplatin and Gemcitabine. Group 2: Participants get only the two chemotherapy drugs. Researchers will group people based on the treatments they had in the past. Researchers will also check: How long the treatment keeps the cancer from growing. This is called progression-free survival (PFS). If the treatment is safe. Researchers will look for adverse events (AE), such as low blood cell counts. How participants feel. This is called health-related quality of life (HRQoL). How the body uses the drug.

This study is a randomized, double-blind, multicenter, placebo-controlled Phase III clinical trial designed to evaluate the efficacy and safety of BEBT-209 in combination with fulvestrant in patients with HR+/HER2- locally advanced or metastatic breast cancer.

This is a multicenter, open-label, two-stage Phase II clinical study to evaluate the safety and efficacy of BEBT-209 capsule in combination with carboplatin and gemcitabine for the treatment of advanced triple-negative breast cancer (TNBC).
