Safety and Efficacy of T-DXd vs. CDK4/6i-based ET as First-line Therapy of HR-positive and HER2-low/Ultralow Advanced Breast Cancer Patients Classified as Non-luminal Subtype

This trial studies a type of advanced breast cancer defined as hormone receptor HR-positive/HER2-negative and classified as non-luminal by gene expression profiling (PAM50). Patients will be treated with trastuzumab deruxtecan (T-DXd) or with physician's choice of CDK4/6 inhibitor (CDK4/6i) plus endocrine therapy (ET). The main purpose of the study is to analyze the efficacy of T-DXd in patients who have HR-positive and HER2-low/ultralow advanced breast cancer classified as non-luminal subtype.

Using FDG-PET/CT to Assess Response of Bone-Dominant Metastatic Breast Cancer, FEATURE Study

This phase II trial studies how well FDG-PET/CT works in assessing the response of patients with breast cancer that has spread to the bones or mostly to the bones (bone-dominant metastatic breast cancer). Diagnostic procedures, such as FDG-PET/CT, may work better in measuring breast cancer activity before and after treatment compared to other standard imaging tests.

ARX788 for Treating Patients With HER2-low Locally Advanced Unresectable or Metastatic Breast Cancer

This phase II trial tests how well ARX788 works in treating patients diagnosed with HER2-low, locally advanced unresectable or metastatic breast cancer. ARX788 is an antibody-drug conjugate (ADC) that is given by infusion (diluted and injected slowly into veins). Antibodies are proteins which are naturally produced by the body's immune system to help fight infections. ARX788 consists of antibodies that have been attached to a toxin that has the potential to kill cancer cells. ARX788 sticks to a protein called human epidermal growth factor receptor (HER2), which is found on some breast cancer cells. Giving ARX788 may be safe and effective in treating patients with HER2-low locally advanced unresectable metastatic breast cancer.

Alpelisib (BYL719) in Combination With Continued Endocrine Therapy Following Progression on Endocrine Therapy in Hormone Receptor Positive, HER2 Negative, PIK3CA Mutant Metastatic Breast Cancer

Patients who have histologically confirmed metastatic or unresectable (not amenable to curative therapy) breast cancer may be screened for eligibility. All patients must have HER2 negative breast cancer with the identified PIK3CA mutation and received at least one line of endocrine therapy. The study will consist of a screening phase, a treatment phase, and a post-treatment phase which includes safety, efficacy, and follow-up. The treatment phase will include taking alpelisib daily in combination with continued use of either Fulvestrant or Aromatase Inhibitor per standard of care until disease progression or unacceptable toxicity.

Trastuzumab Deruxtecan Alone or in Combination With Anastrozole for the Treatment of Early Stage HER2 Low, Hormone Receptor Positive Breast Cancer

This phase II trial investigates how well trastuzumab deruxtecan works alone or in combination with anastrozole in treating patients with HER2 low, hormone receptor positive breast cancer. Trastuzumab deruxtecan is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug called deruxtecan. Trastuzumab attaches to HER2 expressed at low levels on cancer cells in a targeted way and delivers deruxtecan to kill them. Anastrozole works by decreasing estrogen production and suppressing the growth of tumors that need estrogen to grow. This study is evaluating how effective trastuzumab deruxtecan is at treating hormone receptor positive cancer cells that have low levels of HER2 expressed on them when given alone or in combination with anastrozole.

Study of the Monoclonal Antibody IMT-009 in Patients With Advanced Solid Tumors or Lymphomas

This is a Phase 1/2a open-label, multicenter, dose escalation and dose expansion trial in which IMT-009 will be administered by the intravenous (IV) route to participants with solid tumors or lymphomas. The main goals of this study are to: * Find the recommended dose of IMT-009 that can be safely given to participants * Learn more about the side effects of IMT-009 * Learn more about pharmacokinetics of IMT-009 * Learn more about the effectiveness of IMT-009 * Learn more about different pharmacokinetic biomarkers and how they might change in the presence of IMT-009

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.

Predicting clinicAL outcoMes During First-line CDK4/6 Inhibitors Plus Endocrine Therapy in Patients With Advanced Hormone REceptor-poSitive HER2-negative Breast Cancer: the Retrospective-prospective Multicenter Italian PALMARES-2 Study

PALMARES-2 is a retrospective/prospective, observational, multicenter, population-based study, aiming at providing real-world evidences on HR+/HER2- aBC patients treated with first-line CDK4/6i plus ET. The present study has the objective to collect data coming from different sources, i.e. RWD, medical images and biological samples, from patients treated with CDK4/6i as first-line of therapy for HR+/HER2- aBC. In consideration of the complexity of data collected and different objectives of the study, this master protocol foresees different sub-studies, which encompasses different methodologies for data collection, data extraction and analyses.
