• If patient has brain metastasis, documented treatment and stability for at least 30 days by scans and off steroids at the time of enrollment
• Women of child bearing age and actively menstruating must have a negative pregnancy test prior to study enrollment.
• Ability to understand and the willingness to give informed consent

Exclusion Criteria:
