exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the
skin, or in situ cervical cancer that has undergone potentially curative therapy
- Has known active central nervous system (CNS) metastases and/or carcinomatous
meningitis; subjects with previously treated brain metastases may participate provided
