Title:
Phase Ib/II clinical trial of BEBT-908 combined with BEBT-209 in patients with advanced recurrent or metastatic HR+/HER2- breast cancer
Excerpt:
...Patients with advanced recurrent or metastatic breast cancer diagnosed by histology, immunohistochemical detection of HR positive staining cells >= 10% and HER2 negative (receive the latest metastatic tissue sample or previous primary tumor tissue sample test results), menopausal state or receiving LHRH agonist treatment, there is evidence of focal recurrence or metastasis, not suitable for surgical resection or radiation therapy for the purpose of cure; those who meet any of the following can be considered to have reached the menopausal state: (1) Premenopausal/perimenopausal female patients agree to use concomitant luteinizing hormone-releasing hormone (LHRH agonist), and start receiving LHRH agonist treatment at least 28±2 days before the first dose of study dosing can be considered to meet the inclusion criteria3 (Those who have used LHRH agonist for >=21 days but = 60 years; aged = 12 months, follicle-stimulating hormone (FSH) and estradiol (E2) levels in the postmenopausal range without chemotherapy, tamoxifen, toremifene, or ovarian castration within the past year (judged based on the reference range of each research center); (3) For patients aged = 1500/mm^3 (1.5 x 10^9/L); (2) Platelets >= 100000/mm^3 (100 x 10^9/L); (3) Hemoglobin >= 9g/dL (90g/L); (4) Both ALT or AST are l bilirubin (TBIL) =60mL/min (according to Cockcroft and Gault formula); Note: No blood components, hematopoietic-stimulating factors (including granulocyte colony-stimulating factor, granulocyte-macrophage colony-stimulating factor, erythropoietin, and thrombopoietin, etc.) are allowed within the first 14 days of screening laboratory tests. ...

CDK4/6 inhibitors, PI3K/mTOR inhibitors, and HDAC inhibitors as second-line treatments for hormone receptor-positive, HER2-negative advanced breast cancer: a network meta-analysis
Published date:
08/29/2023
Excerpt:
Compared with placebo plus fulvestrant, PFS was significantly improved by CDK4/6 inhibitor plus fulvestrant, mTOR inhibitor plus fulvestrant, mTOR inhibitor plus exemestane, and PI3K inhibitor plus fulvestrant, but not HDAC inhibitor plus exemestane….mTOR inhibitor and CDK4/6 inhibitor-based regimens demonstrated superior clinical efficacy and comparable safety profiles as second-line treatment in patients with HR-positive, HER2-negative advanced breast cancer.
