Ovarian Cancer Clinical Trial

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

Summary

The purpose of this study is to evaluate the safety and pharmacokinetics of enfortumab vedotin as well as assess the immunogenicity and antitumor activity in subjects with metastatic urothelial cancer and other malignant solid tumors that express Nectin-4.

Full Description

All subjects will receive a single 30 minute IV infusion of enfortumab vedotin once weekly for the first 3 weeks of every 4 weeks (i.e., on Days 1, 8, and 15). A cycle is 4 weeks.

This is a 3 part study. Part A will evaluate enfortumab vedotin in subjects with histologically confirmed malignant solid tumors (excluding sarcomas) that are resistant or have recurred. Subjects will continue treatment until disease progression, intolerability of enfortumab vedotin, investigator decision or consent withdrawal. Part A will follow a modified Continual Reassessment Method (mCRM).

Part B, will evaluate enfortumab vedotin in 3 different expansion cohorts: 1) Urothelial cancer subjects with renal insufficiency defined as a Creatinine Clearance ≥ 15 ml/min and < 30 ml/min, 2) subjects with Metastatic Non Small Cell Lung Cancer (NSCLC) and 3) subjects with Metastatic Ovarian Cancer. With the exception of the renal insufficiency cohort, enrollment into Part B will occur at the recommended phase 2 dose (RP2D) established in Part A. Enrollment into the renal insufficiency cohort will begin at starting dose and escalated using a 3 + 3 dose escalation design. Subjects will continue treatment until disease progression, intolerability of enfortumab vedotin or consent withdrawal.

Part C will evaluate enfortumab vedotin at the RP2D (determined from Part A) in subjects who have been previously treated with immune checkpoint inhibitors (CPI) in the metastatic setting. Subjects will continue treatment until disease progression, intolerability of enfortumab vedotin, investigator decision or consent withdrawal.

All subjects will be followed post-treatment through the 30-day Safety Follow-up Visit.

Eligibility Criteria

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 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
Life expectancy of ≥ 3 months
Negative pregnancy test (women of childbearing potential)

Hematologic function, as follows (no red blood cell or platelet transfusions are allowed within 14 days of the first dose of enfortumab vedotin):

Absolute neutrophil count (ANC) ≥ 1.0 x 10^9/L
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 mlmin by Cockcroft-Gault equation or as measured 24 hour urine collection.
Total bilirubin ≤ 1.5 x ULN (upper limit of normal)
Serum albumin ≥2.5 g/dL
Aspartate aminotransferase (AST) ≤ 1.5 x ULN
Alanine aminotransferase (ALT) ≤ 1.5 x ULN
