Trial of Exemestane +/- MM-121 in Postmenopausal Women With Locally Advanced or Metastatic Estrogen Receptor Positive and/or Progesterone Receptor Positive Her2 Negative Breast Cancer

2014-07-24 14:00:53 | BioPortfolio


To determine whether the combination MM-121 + Exemestane in ER+ and/or PR+ breast cancer patients is more effective than Exemestane alone


The study is a double-blind, randomized Phase 2 trial of Exemestane +/- MM-121. The trial is designed to demonstrate whether MM-121 + Exemestane is more effective than Exemestane alone in ER+ and/or PR+ and Her2 negative breast cancer patients that have failed first-line anti-estrogen therapy in the locally advanced or metastatic setting and patients that have progressed during (or within 6 months of completing) adjuvant treatment with a non-steroidal aromatase inhibitor (AI)and/or tamoxifen. Patients will be treated until radiologic or clinical progression of their disease is documented. Local radiologist and/or PI assessment is accepted.

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).

Carbohydrate antigen elevated in patients with tumors of the breast, ovary, lung, and prostate as well as other disorders. The mucin is expressed normally by most glandular epithelia but shows particularly increased expression in the breast at lactation and in malignancy. It is thus an established serum marker for breast cancer.

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.

The phosphoprotein encoded by the BRCA1 gene (GENE, BRCA1). In normal cells the BRCA1 protein is localized in the nucleus, whereas in the majority of breast cancer cell lines and in malignant pleural effusions from breast cancer patients, it is localized mainly in the cytoplasm.
