10. The effects of ATN 161 on the developing human fetus at the recommended therapeutic dose are unknown. For this reason and because antiangiogenic agents are known to be teratogenic, women of child-bearing potential and men with partners of child-bearing potential must agree to use adequate contraception (hormonal and/or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation through the follow up visit 28 days after the last dose of ATN 161. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. Similarly, if the partner of a male patient should become pregnant while he is participating in this study, he should inform his treating physician immediately.
