relapsed after standard therapy, or who have no standard therapy available that
improves progression-free or overall survival by at least three months.

condom, hormonal contraceptive) from the time of signing of the informed consent
form through 21 days after the last dose of study agent, OR
o Agrees to practice true abstinence when this is in line with the preferred and
usual lifestyle of the subject. (Periodic abstinence [e.g., calendar, ovulation,
symptothermal, postovulation methods] and withdrawal are not acceptable
contraception methods.)

stomach or small bowel, or preexisting Crohn's disease or ulcerative colitis or a
preexisting chronic condition resulting in baseline grade 2 or higher diarrhea).
2. Second primary malignancy except most in situ carcinomas (e.g., adequately treated
non-melanomatous carcinoma of the skin) or other malignancy treated at least five
