Phase I/II Study of MK-0752 Followed by Docetaxel in Advanced or Metastatic Breast Cancer

Completed · Phase 1/Phase 2

Conditions studied: Metastatic Breast Cancer

In brief

New and better therapies for locally advanced and metastatic breast cancer are needed because, even if standard treatment is successful in shrinking the cancer, there is still a high chance that the cancer will recur. Recent research suggests that breast tumors have a small number of cells in them that are "breast cancer stem cells", which are very resistant to standard treatment. It is thought that the reason that many patients cannot be cured of their breast cancers is that the stem cells are unable to be killed and remain in the body after standard treatment. Laboratory research has shown that a new drug, MK-0752, can target stem cells and prevent tumor recurrences when the drug is combined with docetaxel, a chemotherapy drug commonly used to treat breast cancer. We know that MK-0752 is safe when given by itself to people. We do not know if treatment with MK-0752 and docetaxel combined is safe or if it will kill "breast cancer stem cells" in people with breast cancer. This clinical trial is being done to determine the safety of several doses of MK-0752 in combination with docetaxel. Preliminary data about the effectiveness of MK-0752 in combination with docetaxel will be collected. Also, tumor biopsy samples will be taken from some patients who have tumors that can be easily biopsied. The samples will be used to perform research tests to help determine if the "breast cancer stem cells" are being killed by the drug combination.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Men or women with metastatic (Stage IV) breast cancer, or with locally advanced breast cancer (Stages IIIA > 10 cm, or Stages IIIB and IIIC) that did not respond to first-line anthracycline-based chemotherapy, for whom docetaxel is a recommended therapy
• Presence of measurable or evaluable disease
• Adequate organ function
• Ability to swallow intact study drug capsules
• Zubrod Performance Status of 0-1 with at least a 3 month life expectancy
• Appropriate time must have elapsed since prior anti-neoplastic therapy with resolution of acute toxicity

You may not qualify if…

• Concurrent treatment with hormonal therapy intended to treat cancer
• Radiotherapy within 7 days prior to first dose
• Symptomatic central nervous system, and/or epidural metastases or symptomatic carcinomatous meningitis or with radiation treatment completed within the past 8 weeks
• Serious comorbid illness which will limit the ability of the patient to safely receive anticancer treatment
• Patients who are pregnant or nursing
• Confounding factors present to provide misinterpretation of data (i.e., concurrent malignancy)
