Active clinical trials for "Breast Neoplasms"

The purpose of this study is to evaluate the efficacy and safety of recombinant anti-EGFR monoclonal antibody（SCT200）in patients with triple receptor negative breast cancer treated after failure of standard therapy (including Anthracyclines and/or Taxanes).

Phase II Pilot Study of Trastuzumab Biosimilar (Herzuma®) plus Gedatolisib in Patients with HER-2 Positive Metastatic Breast Cancer Who Progressed after 2 or more HER-2 directed Chemotherapy

In this phase I feasibility study, the investigators evaluate the combination of lyso-thermosensitive liposomal doxorubicin (LTLD, ThermoDox) with local hyperthermia and cyclophosphamide (C), for the local treatment of the primary breast tumour in patients with metastatic breast cancer. When heated to 40-43 degrees Celsius (ºC), LTLD releases a very high concentration of doxorubicin locally within seconds. Hyperthermia of the primary tumour will be induced by Magnetic Resonance guided High Intensity Focused Ultrasound (MR-HIFU) on a dedicated Sonalleve MR-HIFU breast system. The investigators hypothesize that by substituting doxorubicin (A) in the AC-chemotherapy regimen for the combination of LTLD and MR-HIFU induced hyperthermia, optimal local tumour control can be achieved without compromising systemic toxicity or efficacy. This will be the first study to evaluate LTLD with MR-HIFU hyperthermia in breast cancer patients.

Trastuzumab combined with chemotherapy has been approved as the first line therapy in HER2+ metastatic breast cancer. When patients experienced progression beyond trastuzumab containing therapy, T-DM1 is considered as the second line therapy followed by trastuzumab plus any other chemotherapeutic agents or lapatinib plus capecitabine. A biosimilar drug is a biological product that is highly similar to a licensed biological product, with no clinically meaningful differences in terms of safety, purity, or potency. Several trastuzumab biosimilar products have been approved after efficacy and safety studies which were usually as the first line setting with taxane combined. Even though trastuzumab biosimilar drugs demonstrated similarity of equivalence with trastuzumab in these studies, the efficacy of their second use beyond progression with other chemotherapeutic agents has not been tested yet. In addition, the investigators don't have any data regarding possible cross reactivity between trastuzumab and trastuzumab biosimilar drugs. In this study, the investigators plan multicenter phase II clinical trial to test the efficacy, safety and immunogenicity of trastuzumab biosimilar, Herzuma® in combination with TPC in patients with HER2+ metastatic breast cancer who progressed after 2 or more HER-2 directed chemotherapy.

Pyrotinib is an oral tyrosine kinase inhibitor targeting both HER1, HER2 and HER4 receptors. This study is a single-arm, prospective, single-center clinical study of pyrotinib plus fulvestrant as the therapy HR+/HER2+ metastatic breast cancer.

Pfizer's innovative drug palbociclib (trade name: Ibrance®) got China National Drug Administration (CNDA) approval on July 31, 2018. Palbociclib combined with an aromatase inhibitor can be used to treat hormone receptor-positive/human epidermal growth factor receptor 2-negative locally advanced breast cancer or metastatic breast cancer. This brings more treatment options for hormone receptor-positive/human epidermal growth factor receptor 2-negative locally advanced breast cancer. How to scientifically evaluate the efficacy, tolerability, and safety of palbociclib combined with an aromatase inhibitor and to establish a more suitable treatment strategy for Chinese patients is one of the questions that need to be answered in clinical practice. This multi-center parallel-group randomized controlled trial will address on this issue.

Multi-focal Breast Cancers(MFBC) still have undiscoverable Clinical Significance reflecting on a debatable surgical decision for this Category of breast cancer. A prospective study was conducted using certain surgical technique as a surgical treatment for female patients with operable breast cancer managed at the Surgical Oncology Unit, Alexandria University from May. 2017 to May2018 and will be followed for 3 Years.Analysis will be done to settle a paradigm for surgical management of Multi-focal Breast Cancer

To compare efficacy and safety of adding thoracic paravertebral nerve blocks to modified PEC block versus modified PEC block only in breast cancer surgery. This study evaluate systemic opioid requirement in 48 hours in primary outcome and the analgesic profile ( pain score at rest and on shoulder movement), opioid-related side effects and nerve blocks complications.

This clinical trial aim to evaluate the efficacy and safety of Pyrotinib in combination with nab-paclitaxel in patients with HER2-positive advanced breast cancer.

Overexpression of the HER2 gene accounts for 20% to 30% of breast cancer. Although trastuzumab combined with chemotherapy has become the basic treatment for patients with HER2-positive advanced breast cancer, For patients who have progressed or relapsed after trastuzumab treatment, There are still many issues to explore on the choice of program of retargeted therapy. In HER2-positive advanced breast cancer, the results of Phase I and Phase I/II trials of pyrotinib or pyrotinib combined with capecitabine show that the anti-tumor effect is rapid, efficient and sustainable, and the patient is safe and well tolerated. Capecitabine is an oral cytotoxic drug that has high selectivity and specificity against tumors. Many patients need to adjust the dose due to adverse reactions, especially for patients after multi-line treatment. Previous studies have shown that sustained low-dose capecitabine reduces the adverse effects of the drug while ensuring efficacy. Based on the above, this study is to conduct a single-center, one-arm phase II clinical trial to explore the efficacy and safety of pyrotinib and capecitabine in the treatment of HER2-positive advanced breast cancer.
