• Receiving or having received investigational agents or systemic anti-cancer agents within 14 days of Day 1 of dosing or 28 days for those agents with unknown elimination half-lives or half-lives of greater than 50 hours

• Received extensive radiation therapy including sternum, pelvis, scapulae, vertebrae or skull,week prior to starting study drug, or who have not recovered from side effects of such therapy

• Major surgery to the upper gastrointestinal tract, or inflammatory bowel disease, malabsorption syndrome or other medical condition that may interfere with oral absorption
