NCT07483307

A Study of the Impact of Endocrine Therapy on Surgical Outcomes in People With Breast Cancer

The purpose of this study is to look at how effective neoadjuvant (before surgery) endocrine therapy (NET) is in participants with invasive lobular carcinoma (ILC) who have breast-conserving surgery (BCS). The main purpose of the study is to see if NET reduces the chance of having cancer cells at the edges of tissue removed during surgery (positive margins).

Palazestrant in Combination With Ribociclib for the First-line Treatment of ER+/HER2- Advanced Breast Cancer

This phase 3 clinical trial compares the efficacy and safety of palazestrant with ribociclib to letrozole and ribociclib in women and men who have not received prior systemic anti-cancer treatment for advanced breast cancer.

OP-1250 (Palazestrant) vs. Standard of Care for the Treatment of ER+/HER2- Advanced Breast Cancer

This phase 3 clinical trial compares the safety and efficacy of palazestrant (OP-1250) to the standard-of-care options of fulvestrant or an aromatase inhibitor in women and men with breast cancer whose disease has advanced on one endocrine therapy in combination with a CDK4/6 inhibitor.

Vaccine Therapy in Treating Patients With HER2-Negative Stage III-IV Breast Cancer

This phase I trial studies the side effects and best dose of multiantigen deoxyribonucleic acid (DNA) plasmid-based vaccine in treating patients with human epidermal growth factor receptor 2 (HER2)-negative stage III-IV breast cancer. Multiantigen DNA plasmid-based vaccine may target immunogenic proteins expressed in breast cancer stem cells which are the component of breast cancer that is resistant to chemotherapy and has the ability to spread. Vaccines made from DNA may help the body build an effective immune response to kill tumor cells.

SHARON: A Clinical Trial for Metastatic Cancer Using Chemotherapy and Patients' Own Stem Cells

The clinical trial is a phase 1, single-arm trial that will evaluate the safety of the investigational treatment on metastatic pancreatic cancer and metastatic breast cancer. The investigational treatment will involve 2 cycles of a combination of intravenous melphalan, BCNU, vitamin B12b, and vitamin C with autologous hematopoietic stem cell infusion. A dose-escalation schedule is being employed for the vitamin C.

Prospective Registry of ADC as First- and Second-line Treatment for Breast Cancer

Antibody-drug conjugates (ADCs) have demonstrated substantial improvement in progression free survival (PFS) and overall survival (OS) in phase III clinical trials in patients with metastatic triple negative breast cancer (mTNBC) and hormone receptor positive/HER2 negative (HR+/HER2-) metastatic breast cancer (MBC), offering an effective new treatment strategy. Several outstanding questions drive the decision to use ADC drugs clinically. This is a prospective, multi-site observational study of patients with metastatic breast cancer (mBC) who are being treated with FDA-approved antibody drug conjugates (ADCs) as part of routine care and aims to collect real-world data to evaluate the impact of ADC treatment as part of routine care.

Additional Support Program Via Text Messaging and Telephone-Based Counseling for Breast Cancer Patients Receiving Hormonal Therapy

This phase III trial compares an additional support program (text message reminders and/or telephone-based counseling) with usual care in making sure breast cancer patients take their endocrine therapy medication as prescribed (medication adherence). Medication adherence is how well patients take the medication as prescribed by their doctors, and good medical adherence is when patients take medications correctly. Poor medication adherence has been shown to be a serious barrier to effective treatment for hormone receptor positive breast cancer patients. Adding text message reminders and/or telephone-based counseling to usual care may increase the number of days that patients take their endocrine therapy medication as prescribed.

Neoadjuvant Breast Cancer Time Restricted Eating

A phase II study to evaluate an innovative approach of following time restricted eating (TRE) in patients with HER2- negative breast cancer who will start neoadjuvant chemotherapy (NCT) for a new diagnosis of stage I-III breast cancer. Participants at baseline will have a body mass index (BMI) of (25-40) and engage in a TRE 16:8 schedule which includes 16 hours of fasting and 8 hours of eating. Patients will continue TRE for 16 weeks while receiving NCT. For patients who report at the time of the 2-3 week clinic visit that they are finding it challenging to adhere to the 16:8 TRE, instructions will be provided about alternative measures such as changing the time of the day they fast, dietary modifications and finally changing to a 14:10 schedule if other measures fail. For patients requiring NCT for longer than 16 weeks, they will be encouraged to continue TRE. Adherence calculation for the primary endpoint will include data for the first 16 weeks, and then monitored separately for any additional optional fasting beyond the first 16 weeks. Adherence to TRE will be self-reported by patients daily through electronic surveys through RedCap and approximately every 2-3 weeks (+/- 5 days) by the research team during their clinic visit.
