Patient-Derived Organoids to Functionally Characterize Chemotherapy Resistance in Breast Cancer

This prospective observational study aims to functionally characterize chemotherapy resistance in patients with locally advanced breast cancer undergoing neoadjuvant chemotherapy. Despite standard molecular classification, significant heterogeneity in treatment response exists, and the biological mechanisms underlying chemoresistance remain incompletely understood. In this study, patient-derived organoid (PDO) models will be established from tumor tissues obtained during routine clinical care. These three-dimensional models preserve the biological characteristics of individual tumors and enable ex vivo functional assessment of drug response. Chemotherapy sensitivity and resistance will be evaluated using quantitative parameters including IC50 values, cell viability, and apoptotic response. Functional data obtained from PDO models will be correlated with clinical and pathological treatment outcomes, particularly pathological complete response (pCR), to assess the predictive value of PDO-based assays. In addition, apoptotic biomarkers such as Caspase-3/7 will be measured in serum samples collected during routine clinical evaluation and analyzed in relation to treatment response. Furthermore, selected FDA- and EMA-approved small molecules will be tested in PDO models to evaluate their potential to reverse chemotherapy resistance, supporting drug repurposing strategies. This study aims to establish a functional, patient-specific platform for assessing chemoresistance and to contribute to the development of personalized therapeutic approaches in breast cancer.

A Study to Assess CLBR001+ABBV-461 in Subjects With Locally Advanced or Metastatic Breast Cancer

The goal of this clinical trial is to evaluate CLBR001 and ABBV-461 as a treatment for patients with locally advanced or metastatic breast cancer. The goals are to establish the safety and efficacy of the combination therapy while establishing the optimal biologic doses. Patients will be administered a single infusion of CLBR001 cells followed by cycles of ABBV-461 with regular assessments of safety and disease response to treatment.

Preoperative Shoulder Exercises and Postoperative Inflammation, Pain, and Function After Modified Radical Mastectomy

This study evaluates whether preoperative shoulder range-of-motion exercises influence postoperative inflammatory response, pain, shoulder function, and quality of life in patients with locally advanced breast cancer undergoing modified radical mastectomy.

JSKN016 in Combination With D-0502 for Locally Advanced or Metastatic HR-Positive, HER2-Negative Breast Cancer

This is a multicenter, open-label, Phase Ib/II randomized study designed to evaluate the safety, tolerability, dose-limiting toxicities (DLTs), and preliminary antitumor activity of JSKN016 in combination with the oral selective estrogen receptor degrader (SERD) D-0502 in patients with locally advanced or metastatic hormone receptor-positive (HR+), HER2-negative breast cancer who have previously progressed on CDK4/6 inhibitor-based endocrine therapy. Approximately 60 patients will be randomized in a 1:1 ratio to receive JSKN016 administered intravenously every 2 weeks (Q2W) or every 3 weeks (Q3W), in combination with daily oral D-0502. Each dosing cohort will include a safety lead-in phase to assess DLTs prior to cohort expansion. Tumor response will be assessed according to RECIST v1.1.

A Phase Ib/II Study to Evaluate Multiple Combination Therapies of FWD1802 in Patients With ER+/HER2- BC

This is a Study to Evaluate the Efficacy and Safety of Multiple Combination Therapies with FWD1802 in Subjects with ER-positive/HER2-negative Unresectable Locally Advanced or Metastatic Breast Cancer

Pyrotinib Maleate Tablets in Combination With Dalpiciclib Isethionate Tablets and Standard Endocrine Therapy

This study is a prospective, exploratory clinical study design, and plans to enroll 33 patients with HR+HER2 low expression breast cancer who received pyrotinib combined with darcili and standard endocrine neoadjuvant therapy to evaluate the efficacy of this regimen in HR+HER2 low expression breast cancer. Imaging evaluation was performed according to RECIST 1.1 criteria, and tumor imaging evaluation was performed by the participating center. The pathological evaluation after surgery of neoadjuvant patients was the pCR assessed by the pathologist of the participating center.
