Active clinical trials for "Breast Neoplasms"

The study assesses the efficacy of neoadjuvant treatment with pyrotinib and trastuzumab with chemotherapy, mainly pathological complete response (pCR) rates in the breast and axilla. And also assesses side effects, event-free survival (EFS), disease-free survival (DFS), distant disease-free survival (DDFS), and objective response rates (ORR).

This is a phase I/II, single-arm and open-label single-centre clinical trial with the aim to test the feasibility, safety and the efficacy, in terms of complete pathological response, of preoperative ablative radiotherapy in single fraction for selected breast cancer patients.

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

The purpose of this study is to identify the highest tolerable dose of pyrotinib in combination with vinorelbine and to assess the safety and efficacy of the combination in Patients With HER2-Positive Locally Advanced or Metastatic Breast Cancer. The study will be conducted in two parts. In the first part, testing will be done on up to 12 subjects to determine the highest tolerable dose of pyrotinib and vinorelbine in patients with advanced solid tumors. In the second part of the study, we will explore the safety and efficacy of Pyrotinib + vinorelbine in Patients With HER2-Positive Locally Advanced or Metastatic Breast Cancer Who Have Received Prior Trastuzumab-Based Therapy. Participants will be treated until disease progression (PD), unmanageable toxicity, or study termination.

Despite broad advancements in endocrine therapy for ERα+ breast cancer, resistance ultimately develops. A common driver of resistance are known ESR1 mutations that lead to constitutively active receptor signaling and transcriptional regulation that is always "turned on" despite the absence of estrogen. Patients with ESR1 mutations are expected to have decreased binding affinity for tamoxifen and thus may be underdosed on standard therapy. [18F]-fluoroestradiol Positron Emission Tomography/Computed tomography (FES-PET/CT) imaging is a novel functional imaging technique that can non-invasively measure ERα expression and inhibition in metastatic ERα+ breast cancer. The proposed a pilot study uses FES-PET/CT imaging to measure ERα blockade to determine the optimal dose of tamoxifen in patients with ESR1 mutations.

The purpose of this study is to compare the effect of Eflapegrastim on duration of neutropenia in patients with early-stage breast cancer when administered at varying intervals following Docetaxel and Cyclophosphamide administration.

This is a prospective, randomised, multicenter, no placebo-controlled, open label study for evaluating the efficacy and safety of pyrotinib in women with residual invasive HER2-positive breast cancer after neoadjuvant chemotherapy plus anti-HER2 target therapy. The main purpose is to investigate whether pyrotinib can further reduce the risk of recurrence from previously diagnosed HER-2 positive breast cancer based on the 1-year trastuzumab standard adjuvant treatment with or without pertuzumab.

HS-10352 is a highly potent and selective small molecule inhibitor of phosphoinositide 3-kinase (p110α). In preclinical studies, it demonstrated strong activity against PI3K p110α in vitro and in vivo, and inhibited tumor cell growth. The first-in-human trial is conducted to assess the maximum tolerated dose (MTD) and dose limiting toxicity (DLT), to evaluate the pharmacokinetics, safety and preliminary anti-tumor activity of HS-10352 at single dose and multiple doses.

The primary objective of this study is to compare progression-free survival (PFS) of patients with metastatic triple-negative breast cancer randomised to treatment with standard chemotherapy plus moxifloxacin or placebo.

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.
