Summary
Brief summary (as posted)
This is a study of trastuzumab deruxtecan for the treatment of HER2-positive unresectable or metastatic breast cancer following two or more prior anti-HER2 based regimens. Participants will receive this study drug along with a cancer drug, an immune checkpoint inhibitor, anti-PD1, called nivolumab. The study will be done in two parts: * Part 1 is to identify the recommended dose to use for treatment. * Part 2 is to find out how well the combination works, and how safe and tolerable it is.

- description
- Participants with HER2-expressing breast cancer who received starting intravenous dose of trastuzumab deruxtecan at 3.2 mg/kg and a fixed intravenous dose of 360mg of nivolumab every 3 weeks (Q3W). Escalating/de-escalating doses of trastuzumab deruxtecan in combination with a flat dose of nivolumab was administered on Day 1 of each 21-day cycle. The DLT observation period will be the first 2 cycles.

Has pathologically documented breast cancer or urothelial cancer that is unresectable or metastatic, and refractory to or intolerant of existing therapy(ies) known to provide clinical benefit, and as specified in each study cohort 4. Has an adequate archival tumor sample available for the central laboratory to determine eligibility to participate 5. Has at least 1 measurable lesion per RECIST version 1.1 6. Has cardiac, bone marrow, kidney, liver, blood and clotting test results required per protocol 7. Has had an adequate washout period before enrollment since previous surgery and other treatment 8. If reproduction is possible, agrees to use protocol-defined methods of contraception (or completely abstain from heterosexual intercourse) from screening to at least 7 months for females and males after the last dose of study drug 9. Agrees to avoid harvesting sperm or ova for any reason from screening to at least 7 months for females and males after the last dose of study drug 10. Has a life expectancy of at least 3 months Exclusion Criteria: 1. Has received prior treatment with nivolumab or trastuzumab deruxtecan 2.
