T-DM1 and Non-pegylated Liposomal Doxorubicin in HER2-positive Metastatic Breast Cancer

2015-09-30 08:38:23 | BioPortfolio

Summary

The primary goal is to determine the maximum tolerated dose (MTD) of the combination of T-DM1 and non-pegylated liposomal doxorubicin in metastatic breast cancer (mBC) patients previously treated with taxanes and trastuzumab-based therapy.

In addition, pharmacokinetic data on the combination of T-DM1 and lyposomal doxorubicin will be obtained.

Description

Subjects: Age ≥ 18 years with HER2-positive metastatic breast cancer that have relapsed or progressed on or after taxanes and trastuzumab-based therapy. Subjects must have histologic or cytologic confirmation of the HER2-positive metastatic breast cancer. Evidence of measurable or evaluable metastatic disease is required.

Primary objective:

- To determine the maximum tolerated dose (MTD) of the combination of T-DM1 and non-pegylated liposomal doxorubicin in metastatic breast cancer (mBC) patients previously treated with taxanes and trastuzumab-based therapy.

Secondary objectives:

- To determine the efficacy of the combination of T-DM1 and non-pegylated liposomal doxorubicin, defined by the overall response rate (ORR), clinical benefit rate (CBR), number of progressions and number and reasons for deaths.

- To assess the safety profile of the combination of T-DM1 and non-pegylated liposomal doxorubicin, defined by all toxicities reported during the study.

- To evaluate the cardiac safety of the combination of T-DM1 and non-pegylated liposomal doxorubicin measured by LVEF as assessed by echocardiography, cardiac troponin I and B-type natriuretic peptide (BNP) levels.

- To evaluate the potential role of single nucleotide polymorphisms (SNP) in the predisposition for developing cardiotoxicity.

- To analyze the pharmacokinetics (PK) profile of T-DM1 and its metabolites and non-pegylated liposomal doxorubicin.

Type of study: This is a prospective dose-finding, multicenter and open-label phase I clinical trial.

Treatment: Trastuzumab emtansine (T-DM1) will be administered at a fixed dose of 3.6 mg/kg IV on Day 1 every 3 weeks and three cohorts of patients with three different dose levels of conventional non-pegylated liposomal doxorubicin (45 mg/m2, 50 mg/m2 and 60 mg/m2) IV on Day 1 in cycles of 21 days each are planned.

Medical and Biotech [MESH] Definitions

A humanized monoclonal antibody against the ERBB-2 RECEPTOR (HER2). As an ANTINEOPLASTIC AGENT, it is used to treat BREAST CANCER where HER2 is overexpressed.

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

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.

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)

A deoxycytidine derivative and fluorouracil PRODRUG that is used as an ANTINEOPLASTIC ANTIMETABOLITE in the treatment of COLON CANCER; BREAST CANCER and GASTRIC CANCER.
