A Study of Escalating Doses of ASG-22CE Given as Monotherapy in Subjects With Metastatic Urothelial Cancer and Other Malignant Solid Tumors That Express Nectin-4
This research study will be of the investigational product, ASG-22CE that has only been administered to a small number of human subjects to date.There are three main purposes to this study. The first purpose is to test the safety of the investigational medicine at different dose levels. We want to find out what effects, good and/or bad, it has on metastatic urothelial cancer. The second purpose of this study is to measure the levels of the investigational medicine in blood at different times. The third purpose is to see whether the investigational medicine has any effect in the control of cancer.
Stanford is currently not accepting patients for this trial.

- Drug: enfortumab vedotin
- 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.

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 CPI-Treated Expansion Cohort: Subject must have received prior treatment with
a CPI in the metastatic setting.
- Subjects must have measurable disease according to RECIST (version 1.1)
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1

- Platelet count ≥ 100 x 10^9/L
- Hemoglobin ≥ 9 g/dL
- Renal function, as follows: Dose Escalation, NSCLC, Ovarian, and CPI Treated Expansion
Cohorts: creatinine clearance of ≥ 30 mL/min by the Cockcroft-Gault equation or as
measured by 24 hour urine collection. For the Renal Insufficiency Expansion Cohort:
creatinine clearance estimate ≥15 ml/min and <30 ml/min by Cockcroft-Gault equation or
as measured by 24 hour urine collection.
