Inclusion Criteria: * Dose Escalation, Renal insufficiency and CPI-Treated Expansion cohorts: Histologically confirmed Transitional Cell Carcinoma of the Urothelium (TCCU) (i.e., cancer of the bladder, renal pelvis, ureter, or urethra). Subjects with Urothelial Carcinoma with squamous differentiation or mixed cell types are eligible. * Ovarian Expansion Cohort: Subjects with recurrent disease or histologically or cytologically confirmed Stage III/IV diagnosis of epithelial ovarian cancer, fallopian tube cancer, or primary peritoneal carcinoma who have previously progressed while receiving or within 6 months of completing a platinum-containing regimen. * NSCLC Expansion Cohort: Histologic or cytologic diagnosis of NSCLC (squamous or non-squamous or NSCLC-not specified) * Dose Escalation, Renal insufficiency, NSCLC and CPI-Treated Expansion Cohorts: For subjects with urothelial cancer and NSCLC: Subjects must submit a tumor tissue for Nectin-4 expression. Enrollment for these subjects is not dependent on the immunohistochemistry using the H-Score (IHC H-Score). * Ovarian Expansion Cohort: Subjects must have tumor tissue positive (IHC H-score ≥150) for Nectin-4 expression * For Dose Escalation, NSCLC and Ovarian Expansion Cohorts: Subject must have failed at least one prior chemotherapy regimen for metastatic disease (urothelial and bladder cancer subjects are not required to have failed prior chemotherapy regimen if considered unfit for cisplatin-based chemotherapy) * For the …

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
