Detailed Description
AGS-22M6E and ASG-22CE are fully human monoclonal antibody conjugated to a cytotoxic agent monomethyl auristatin E (MMAE) targeting Nectin-4 (Agensys code name AGS-22). The main difference between AGS-22M6E and ASG-22CE is the change in cell line for antibody production. AGS-22M6E and ASG-22CE will be administered at mg/kg doses based on the subjects weight at baseline and doses will not change unless the subjects weight changes by ≥ 10% from their baseline weight or the investigational product Dosage Assessment criteria is met.
Subjects will be prescreened for Nectin-4 expression prior to undergoing screening procedures for the main study. Subjects with tumors positive for Nectin-4 expression may be screened for eligibility into the main study. The dose escalation period is estimated to take between 12 and 18 months depending on whether 3 or 6 subjects are enrolled in a given dose cohort, and the availability of consenting subjects.
Subjects will be treated in the dose escalation phase of the study until the maximum tolerated dose (MTD) and recommended dose for expansion (RDE) has been determined by the data review team (DRT). After the RDE has been determined, subjects will be enrolled into 1 of 3 expansion cohorts. There will be 3 expansion cohorts, each targeting a specific cancer (i.e.,Breast, Bladder and Lung plus other solid tumor cancers). The DRT may recommend stopping the study, adjusting the dose or amending the trial at any time.
The clinical bridging to the ASG-22CE involves treating the subjects with ASG-22CE, irrespective of cancer type, at the next lowest dose level previously determined to be safe for AGS-22M6E. After the initial subjects are treated at the bridging dose with ASG-22CE and have completed the safety assessment, future subjects will only be treated with ASG-22CE throughout the remainder of the study.
A disease assessment will be performed by the investigator at Week 8 (± 14 days). Subjects without evidence of disease progression may continue to receive treatment until disease progression or intolerability.

Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria: (For Dose Escalation and Dose Expansion)
- Subjects must have a tumor positive for Nectin-4 expression (as measured by central laboratory using primary or metastatic tumor tissue
- Histologically confirmed malignant solid tumors (excluding sarcoma) that have failed all FDA approved therapies indicated for the type of metastatic cancer and line of therapy or for which they were not a candidate to receive treatment
Measurable disease according to RECIST criteria (version 1.1) (Eisenhauer, et. al.) defined as tumor lesions that are accurately measured in at least one dimension (longest diameter in the plane of measurement is to be recorded) with a minimum size of:
- 10mm by CT scan (CT scan slice thickness no greater than 5mm
- 10 mm caliper measurement by clinical exam (lesions which cannot be accurately measured with calipers should be recorded as nonmeasurable
- 20 mm by chest X-ray
- ≥ 15 mm in short axis for lymph nodes when assessed by CT scan (CT scan slice thickness recommended to be no greater than 5 mm)
Note: bone lesions, ascites, and pleural effusions are not considered measurable lesions
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
- Negative pregnancy test (women of childbearing potential)
Hematologic function, as follows:
- a. Absolute neutrophil count (ANC) ≥ 1.0 x109 /L
- b. Platelet count ≥ 100 x 109/L
- c. Hemoglobin ≥ 8.5 g/dL
- Renal function, as follows: serum creatinine ≤ 2.0 mg/dL, or measured 24 hour creatinine clearance of ≥ 45 mL/min
- Total bilirubin ≤1.5 x upper limit of normal (ULN)
- Serum albumin > 2.5 g/dL
- Aspartate aminotransferase (AST) ≤ 1.5 x ULN
- Alanine aminotransferase (ALT) ≤ 1.5 x ULN
- Gamma GT ≤1.5 ULN
- International normalized ratio (INR) < 1.5 (or ≤ 3 if on warfarin or other medications for therapeutic anticoagulation)
- Women and men of childbearing potential must be advised and agree to practice effective methods of contraception during the course of the study
Inclusion Criteria for Dose Expansion Only:
