Study of Trastuzumab Deruxtecan (T-DXd) vs Investigator's Choice Chemotherapy in HER2-low, Hormone Receptor Positive, Metastatic Breast Cancer

This study will evaluate the efficacy, safety and tolerability of trastuzumab deruxtecan compared with investigator's choice chemotherapy in human epidermal growth factor receptor (HER)2-low, hormone receptor (HR) positive breast cancer patients whose disease has progressed on endocrine therapy in the metastatic setting.

A Study of AND019 in Women With ER Positive HER2 Negative Advanced or Metastatic Breast Cancer

This is a first in human dose escalation and expansion study to evaluate the safety, tolerability, pharmacokinetic (PK), pharmacodynamic (PD) activity, and preliminary anti-tumor activity of AND019 in postmenopausal women with advanced or metastatic estrogen receptor (ER)-positive (human epidermal growth factor receptor 2 \[HER2\]-negative) breast cancer.

A Study to Learn About the Study Medicine Called PF-07220060 in Combination With Fulvestrant in People With HR-positive, HER2-negative Advanced or Metastatic Breast Cancer Who Progressed After a Prior Line of Treatment

The purpose of this study is to learn about the safety and how effective the study medicine (PF-07220060) plus fulvestrant is compared to the study doctor's choice of treatment in people with advanced or metastatic breast cancer. Advanced cancer is the one that is unlikely to be cured or taken care of with treatment. Metastatic cancer is the one that has spread to other parts of the body. This study is seeking female and male participants who: * are 18 years of age or older; * are hormone receptor (HR)-positive and human epidermal growth factor receptor 2 (HER2)-negative; * have advanced or metastatic breast cancer after taking other treatments before this study; * have not taken or need to take medications that are not allowed by the study protocol; * do not have any medical or mental conditions that may increase the risk of study participation. Half of the participants will take PF-07220060 two times daily by mouth along with fulvestrant. Fulvestrant will be given as a shot into the muscle. The other half will take the study doctor's choice of treatment which can either be: * Fulvestrant alone taken as shot into the muscle. * Everolimus along with exemestane taken once daily by mouth. This study will compare the experiences of participants receiving the study medicine plus fulvestrant to those who are receiving the study doctor's choice of treatment. This will help decide if the study medicine is safe and effective. Participants will receive study treatment and/or will be in the study until: * imaging scans (such as an MRI and/or CT) show that their cancer is getting worse. * the study doctor thinks the participant is no longer benefitting from the study medicine. * has side effects that become too severe. A side effect is a reaction (expected or unexpected) to a medicine or treatment you take. * the participant chooses to stop taking part.

Evaluating the Addition of Elacestrant (Oral SERD) to Olaparib (PARP-inhibitor) in Patients With Advanced/Metastatic HR+/HER2- Breast Cancer

Trial design: Phase II, prospective, multi-center, randomized, open label, parallel group study in patients with HR-positive, HER2-negative locally advanced or metastatic breast cancer with gBRCA1/2 mutation, with 2:1 randomization into Arm A (olaparib + elacestrant) or arm B (olaparib). Treatment in either arm will be given until disease progression, unacceptable toxicity, withdrawal of patient´s consent to study participation, or end of study. Trial population: Patients with HR-positive, HER2-negative locally advanced or metastatic breast cancer with gBRCA1/2 mutation, with an indication for standard-of-care PARP inhibitor therapy and planned treatment with olaparib, an ECOG performance status of 0-2 and life expectancy of \> 6 months, with normal bone marrow and kidney functions and no active or newly diagnosed central nervous system (CNS) metastases or symptomatic metastatic visceral disease at risk of life-threatening complications. Interventions: Patients randomized to Arm A will receive 600 mg olaparib daily and 400 mg elacestrant daily, while patients randomized to Arm B will receive 600 mg olaparib daily. Blood tests (hematology, biochemistry) will be performed at the beginning of every cycle, and imaging for tumor assessment (chest and abdominopelvic imaging) as well as QoL assessments will be performed every three months and in case of suspicion of progression/end of study.

The Efficacy of Oral Cryotherapy in Preventing TROP2-ADC-Induced Oral Mucositis in Patients With Advanced Breast Cancer

The incidence of oral mucositis associated with TROP2-ADC therapy in patients with advanced breast cancer is notably high. Identifying effective preventive and therapeutic strategies is essential for enhancing patient quality of life and optimizing treatment outcomes. Oral cryotherapy has been demonstrated to be efficacious in mitigating oral mucositis induced by radiotherapy and chemotherapy. Consequently, this study seeks to investigate the potential preventive efficacy of oral cryotherapy on TROP2-ADC-induced oral mucositis in patients with advanced breast cancer
