Safety, Tolerability, and Pharmacokinetics of Proxalutamide Therapy in Women With Metastatic Breast Cancer

2019-10-01 07:55:13 | BioPortfolio


This study is a multi-center, open-label, dose-esclation I/Ib clinical study to explore safety, efficacy an pharmacokinetics of proxalutamide in patients with metastatic breast cancer.

This study includes two stages, stage I: single- and multiple-dose tolerance and pharmacokinetic study; stage 2: preliminary efficacy and safety study.


This study is a multi-center, open-label, dose-esclation study.

Subjects will be enrolled to the 100mg, 200mg, 300mg, 400mg and 500mg group in turn. Unless DLT was found, the dose esclation will continue. 28 days of DLT observation period is needed after 7-day single dose administration, until disease progression, intolerable toxicities (AEs), or withdrawn consent.

After the completion of stage 1, 2 doses for the stage 2 will be determined. In stage 2, patients with AR-positive metastatic breast cancer will be selected to explore the efficacy and safety of proxalutamide, and biomarkers will be explored.

Medical and Biotech [MESH] Definitions

Metastatic breast cancer characterized by EDEMA and ERYTHEMA of the affected breast due to LYMPHATIC METASTASIS and eventual obstruction of LYMPHATIC VESSELS by the cancer cells.

Abnormal accumulation of lymph in the arm, shoulder and breast area associated with surgical or radiation breast cancer treatments (e.g., MASTECTOMY).

An estrogen responsive cell line derived from a patient with metastatic human breast ADENOCARCINOMA (at the Michigan Cancer Foundation.)

A synthetic long-acting agonist of GONADOTROPIN-RELEASING HORMONE. Goserelin is used in treatments of malignant NEOPLASMS of the prostate, uterine fibromas, and metastatic breast cancer.

A infiltrating (invasive) breast cancer, relatively uncommon, accounting for only 5%-10% of breast tumors in most series. It is often an area of ill-defined thickening in the breast, in contrast to the dominant lump characteristic of ductal carcinoma. It is typically composed of small cells in a linear arrangement with a tendency to grow around ducts and lobules. There is likelihood of axillary nodal involvement with metastasis to meningeal and serosal surfaces. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1205)
