Basic Information

• Recruitment Status: RECRUITING

Brief Summary

Triple-negative breast cancer (TNBC) accounts for about 20% of clinical breast cancer. Clinical characteristics include early onset, high malignancy and heterogeneity. There is no effective drug target for TNBC, resulting in poor outcomes, high relapse rate and distant metastasis. So, further research on TNBC pathological features is particularly important.

Compared with the solvent-based paclitaxel, albumin-bound paclitaxel (nab-P) demonstrates a stronger therapeutic effect. With albumin nanoparticles as a carrier, nab-P increases the concentration of extra-tumor drugs by passing through the albumin receptor (Gp60) transmembrane pathway and the secreted protein acidic and rich in cysteine (SPARC) approach that binds to the extracellular matrix of the tumor. Numerous clinical trials have found that nab-P is superior to the solvent-based paclitaxel in the treatment of breast cancer, especially in breast cancer with poor prognosis. However, the current efficacy of nab-P in the treatment of TNBC has not been fully verified. The mechanism underlying the killing effect of nab-P on TNBC breast cancer cells remains unclear yet. This trial will compare the therapeutic effect of nab-P with solvent-based paclitaxel in TNBC patients, and seek for important scientific clues, scientific evidence, and clinical data for nab-P in the treatment of TNBC.

Detailed Description

Breast cancer has been one of the most common malignant tumors with highest morbidity and mortality that threatens women's health worldwide. Among US women, there were 250,000 new invasive breast cancers and 40,000 breast cancer deaths in 2017. In the US, 12.4% women develop breast cancer in their lifetime, and the incidence of breast cancer in women over 50 years of age has increased significantly. Although the development of molecular typing and comprehensive treatments have significantly improved the prognosis of breast cancer patients, the recurrence and metastasis of breast cancer is still the main cause of death in breast cancer patients.

TNBC accounts for about 20% of clinical breast cancer. Clinical characteristics include early onset, high malignancy and heterogeneity. There is no effective drug target for TNBC, resulting in poor outcomes, high relapse rate and distant metastasis. So, further research on TNBC pathological features is particularly important.

Paclitaxel is a natural secondary metabolite isolated and purified from the bark of Taxus chinensis. It has been clinically proven to have a good anti-tumor effect. However, polyoxyethylene castor oil/ethanol is often used as a solvent for paclitaxel in clinical practice, and this solvent-based paclitaxel is prone to causing severe allergic reactions, even aggravating myelosuppression and neurotoxicity. In addition, the solvent-based paclitaxel can also influence the efficacy of other drugs by inhibiting albumin-mediated drug delivery. nab-P is a novel paclitaxel that can compensate for the adverse effects of solvent-based paclitaxel and have good efficacy and safety. Compared with the solvent-based paclitaxel, nab-P demonstrates a stronger therapeutic effect. With albumin nanoparticles as a carrier, nab-P increases the concentration of extra-tumor drugs by passing through the albumin receptor (Gp60) transmembrane pathway and the secreted protein acidic and rich in cysteine (SPARC) approach that binds to the extracellular matrix of the tumor. Numerous clinical trials have found that nab-P is superior to the solvent-based paclitaxel in the treatment of breast cancer, especially in breast cancer with poor prognosis. However, the current efficacy of nab-P in the treatment of TNBC has not been fully verified. The mechanism underlying the killing effect of nab-P on TNBC breast cancer cells remains unclear yet.

This trial will compare the therapeutic effect of nab-P with solvent-based paclitaxel in TNBC patients, and seek for important scientific clues, scientific evidence, and clinical data for nab-P in the treatment of TNBC.
