• All patients should have received at least one line of chemotherapy in either the advanced or neo/adjuvant setting and hormonal therapy (where appropriate); participants who have previously been treated with endocrine therapy only, and later develop triple negative disease are eligible as long as they have had one line of chemotherapy in either the advanced or neo/adjuvant setting

• Women of child-bearing potential (WOCBP) and their partners must agree to use adequate contraception (barrier method of birth control; abstinence) prior to study entry, for the duration of study participation and for 5 months following last dose of investigational drug; after confirmation of negative pregnancy test at screening, should a WOCBP become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician and the investigator immediately; the outcome of the pregnancy will be followed and reported to Bristol-Myers Squibb (BMS) * WOCBP are any females (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meet the following criteria: ** Have not undergone a hysterectomy or bilateral oophorectomy; OR ** Have not been naturally postmenopausal for at least 12 consecutive months (i.e.: has had menses at any time in the preceding 12 consecutive months)
