7 active trials for Hormone Receptor Positive Breast Cancer

A Global Study to Compare the Effects of Fulvestrant and Arimidex in a Subset of Patients With Breast Cancer.

The purpose of the study is to compare how treatment with Fulvestrant (FASLODEX) or Anastrozole (ARIMIDEX) effects disease progression for women with locally advanced or metastatic breast cancer who have not had prior hormonal treatment.

WI231696: Bosutinib, Palbocicilib and Fulvestrant for HR+HER2- Advanced Breast Cancer Refractory to a CDK4/6 Inhibitor

This is an open-label, single-arm, phase I trial. It is designed with a conservative dose escalation plan to ensure patient's safety and with a strong translational component to inform if target inhibition is achieved. With concerns regarding safety, based on extensive available pharmacokinetic data and clinical efficacy experience, bosutinib will be given 5-days in a row followed by 2 days rest in a weekly basis, instead of daily. The protocol will enroll patients per 3+3 escalation design. The Dose Limiting Toxicity (DLT) observation period is 28 days. At the end of DLT observation period of each cohort of 3 patients, decision will be made regarding further escalation or de-escalation according to this plan. Once the MTD of the combination is reached, the safety data will be analyzed. There will be no dose reductions during DLT observation period. Dose reduction within patients (individually) is allowed after the 4-week DLT observation period. Treatment in this phase I trial will be administered until there is disease progression or unacceptable toxicity.

Efficacy and Safety of Leuprorelin 3M in Premenopausal Women With Hormone Receptor-positive Breast Cancer

Leuprorelin, a LHRH agonist, acts as a potent inhibitor of gonadotropin secretion and is commonly used for the treatment of hormone-responsive prostate cancer, premenopausal HR+ breast cancer, endometriosis and uterine fibroids. It is currently available in 1M, 3M, 6M for subcutaneous administration. Initially administration would stimulate an increase in LH and FSH, causing a transient increase of E2 in 2-4 weeks. Continuous administration results in a subsequent decrease in E2 levels, as a result of decreased levels of luteinizing LH and FSH. After stopping injection, ovarian function could gradually recover. Adverse events related to leuprorelin include flushing, mood swings and urogenital symptoms. At present, the treatment of premenopausal breast cancer mainly includes 1M and 3M GnRHa. Leuprorelin 11.25mg dosage form is currently the only 3M GnRHa in China that has gotten breast cancer indications. The use of 3M GnRHa could improve patients' compliance and reduce injection discomfort. However, previous studies about GnRHa alone or in combination with TAM or AIs usually used 1M GnRHa. There have been few studies reporting the suppression effects of E2 levels and clinical outcome with leuprorelin 3M in combination with TAM or AIs.

A Single Arm Phase II Study of ADjuvant Endocrine Therapy, Pertuzumab, and Trastuzumab for Patients With Anatomic Stage I Hormone Receptor-positive, HER2-positive Breast Cancer

This research study is studying a combination of HER2-directed therapies (trastuzumab and pertuzumab) and hormonal therapy as a treatment after surgery for hormone receptor positive breast cancer. The study drugs involved in this study are: A combination of trastuzumab and pertuzumab given as an injection under the skin (PHESGO) Hormonal (endocrine) Treatment

Pyrotinib in Combination With Neoadjuvant Chemotherapy in HR+/HER2-, HER4 High Expression Breast Cancer Patients: A Phase II Trial

This is a Phase II, single-center, double-blind, placebo-controlled, randomized study of Pyrotinib in combination with Doxorubicin/Epirubicin and Cyclophosphamide followed by Docetaxel/nab-Paclitaxel as neoadjuvant therapy for women with hormone receptor positive HER2-negative stage II to III breast cancer. Patients randomized to the study arm/control arm will receive standard neoadjuvant chemotherapy in combination with pyrotinib/placebo, respectively. The primary endpoint of the study is the total pathological complete response (pCR) rate. Secondary endpoints include the pCR rate in breast only, objective response rate(ORR), event-free survival, overall survival, and toxicity. We will also explore potential prognostic and predictive biomarkers.

First-in-human Study of DS-1062a for Advanced Solid Tumors (TROPION-PanTumor01)

This study is one single group of participants with non-small cell lung cancer (NSCLC) who have not been cured by other treatments. It is the first time the drug has been used in humans, and will be in two parts. The primary purpose of the parts are: Dose Escalation: To investigate the safety and tolerability and to determine the maximum tolerated dose (MTD) and the recommended dose for expansion (RDE) of DS-1062a Dose Expansion: To investigate the safety and tolerability of DS-1062a in additional solid tumors This study is expected to last approximately 6 years from the time the first participant is enrolled to the time the last subject is off the study. Study sites are located in both the United States and Japan. The number of treatment cycles is not fixed in this study. Participants who continue to benefit from the study treatment may continue, unless: they withdraw their disease gets worse they experience unacceptable side effects.

CDK4/6-inhibitor or Chemotherapy, in Combination With ENDOcrine Therapy, for Advanced Breast Cancer / KENDO

Prospective, open label, multicenter, group sequential response adaptive randomized phase 2 study, comparing two treatments for locally advanced or metastatic luminal breast cancer: Arm A: concomitant cyclin-dependent Kinase 4/6 (CDK4/6) inhibitor (palbociclib, ribociclib or abemaciclib) plus endocrine therapy (aromatase inhibitor [AI] or fulvestrant) Arm B: chemotherapy plus endocrine therapy (AI or fulvestrant, administered either concomitantly from the beginning of chemotherapy or sequentially after 4-6 months of chemotherapy) Treatments will continue until disease progression or toxicity or patient refusal.
