Active clinical trials for "Breast Neoplasms"

This study was a single-arm, open-label, phase II study of breast cancer patients with brain metastases. Eligible patients received a regimen of eutidrone(30mg/m2/d,iv,d1-5,21d/cycle), etoposide(30mg/m2/d,iv,d1-3,21d/cycle), and bevacizumab (10mg/kg,d1,21d/cycle).At least 4 to 6 cycles were administered, and if patients had a response or stable disease, bevacizumab was used as maintenance therapy until disease progression or intolerable toxicity.

The main purpose of this study is to evaluate the efficacy and safety of GB491 combined with Letrozole versus placebo combined with Letrozole in the treatment of HR+/HER2- locally advanced or metastatic breast cancer without prior systemic antitumor therapy

To explore the efficacy and safety of Chidamide combined with endocrine for maintenance therapy after first-line chemotherapy for HR+/HER2- breast cancer

CDK4/6 inhibitors are currently the standard treatment for female breast cancer patients with HR+ tumors. However, there is no established standard treatment for patients who experience treatment failure with CDK4/6 inhibitors. The MAINTAIN study has shown clinical benefits by switching to Ribociclib and changing endocrine therapy after progression on CDK4/6 inhibitors. We hypothesize that combining Dalpiciclib with physician-selected endocrine therapy, following treatment failure with CDK4/6 inhibitors, would similarly lead to improved patient survival. In this study, 18F-FES PET/CT will be employed as a non-invasive alternative to biopsy techniques for evaluating the expression of ER in various systemic lesions of the patients.

Aromatase inhibitor (AI) + CDK4/6 inhibitor is settled down as the standard first line therapy for HR+/HER2- metastatic breast cancer and all three CDk4/6 inhibitors, palbociclib, ribociclib, and abemaciclib are currently available for same indications. However, there is no effective treatment strategy for patients who have progressed on AI+CDK4/6 inhibitor. In particular, the clinical efficacies of subsequent hormone therapy are lowered when ESR1 mutations, one of mechanisms of AI resistance occur. In the PADA-1 trial, when ESR1 mutations in ctDNA were detected in patients treated with AI+CDK4/6 inhibitor, AI was switched to fulvestrant even if disease progression was not confirmed clinically. As a result, the median PFS was prolonged by about 8 months in this switching group compared to the group in which AI was continued. The results of this study suggested that delaying the occurrence of ESR1 mutations and early response to them are necessary to increase the effectiveness of hormone therapy. In SWOG S0226 study, fulvestrant + AI combination showed significant benefits in PFS and OS compared to AI monotherapy as the first line therapy. Based on these results, the NCCN guideline suggests fulvestrant + AI combination as one of the first line hormone therapy options. However, the clinical effect of AI + fulvestrant + CDK4/6 inhibitor has not been investigated yet. Therefore, the investigators are planning to compare the clinical efficacy of AI+ fulvestrant + CDK4/6 inhibitor and AI+CDK4/6 inhibitor, and to investigate if a triple combination regimen can delay the emergence of ESR1 mutations and modulate occurred ESR1 mutations.

The aim of this study was to evaluate whether the progression-free survival of SHR-A1811 was superior to investigator-selected chemotherapy in patients with HER2-low recurrent/metastatic breast cancer. To evaluate whether SHR-A1811 is superior to investigator-selected chemotherapy in patients with HER2-low recurrent/metastatic breast cancer.

The study is being conducted to assess the efficacy and safety of anthracycline-containing ddEC-THP intensive regimen and an anthracycline-free TCbHP neoadjuvant therapy for HER2-positive breast cancer

The purpose of this study is to evaluate the safety and efficacy of samuraciclib in combination with fulvestrant versus fulvestrant alone in adult participants with metastatic or locally advanced Hormone Receptor (HR) positive and Human Epidermal Growth Factor Receptor (HER)2-negative breast cancer.

This is an international, multisite, open-label, Phase 1b/2 study, to confirm safety and efficacy of samuraciclib in combination with elacestrant in adult participants with metastatic or locally advanced Hormone Receptor (HR) positive and Human Epidermal Growth Factor Receptor (HER)2-negative breast cancer.
