Phase 2 |
Detailed Description
Enfortumab vedotin is an antibody-drug conjugate that delivers the microtubule-disrupting agent monomethyl auristatin E (MMAE) to cells expressing Nectin-4. Enfortumab vedotin is FDA approved for bladder cancer.
This is a phase II, open-label, study to evaluate the efficacy, safety and tolerability of Enfortumab vedotin in participants with previously treated locally advanced, recurrent, or metastatic pancreatic adenocarcinoma

Outcome Measures
Primary Outcome Measures
- Overall Response Rate (ORR) [Every 8 weeks until disease progression or end of study (approximately 2 years), whichever is earlier]
To determine anti-tumor activity by overall response rate (ORR) using RECIST 1.1
Secondary Outcome Measures
- Safety and Tolerability [Adverse Event Collection and Review will occur on Days 1,8,15 for each 28-day cycle until disease progression or end of treatment (approximately 2 years)]
To determine treatment safety based on toxicities evaluated according to National Cancer Institute (NCI)-Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 in patients who have received at least one dose of enfortumab vedotin
- Duration of Response (DOR) [approximately 2 years]
To determine anti-tumor activity by duration of response (DOR)
- Disease Control Rate (DCR) [approximately 2 years]
To determine anti-tumor activity by disease control rate (DCR)
- Progression Free Survival (PFS) [Every 8 weeks until disease progression or subsequent therapy assessed up to 2 years]
To determine progression free survival (PFS)
- Overall Survival (OS) [Every 3 months for 12 months after End of Treatment]
To determine overall survival (OS)
Eligibility Criteria
Criteria
Inclusion Criteria:

Women of child-bearing potential and men with partners of child-bearing potential must agree to practice sexual abstinence or to use the forms of contraception listed in Child-Bearing Potential/Pregnancy section for the duration of study participation and
-
Females: at least 2 months after the last dose of the study medication.
-
Males: at least 4 months after the last dose of the study medication.
Exclusion Criteria:
-
Simultaneously enrolled in any therapeutic clinical trial
-
Current or anticipating use of other anti-neoplastic or investigational agents while participating in this study
-
Diagnosed with a psychiatric illness or is in a social situation that would limit compliance with study requirements
-
Has a known allergic reaction to any excipient contained in the study drug formulation
-
Active Grade 3 (per the NCI CTCAE, Version 5.0) or higher viral, bacterial, or fungal infection within 2 weeks prior to the first dose of study treatment.
-
Ongoing sensory or motor neuropathy Grade 2 or higher.
-
Active central nervous system (CNS) metastases. Patients with treated CNS metastases are permitted on study if all the following are true:
-
CNS metastases have been clinically stable for at least 6 weeks prior to screening and baseline scans show no evidence of new or enlarged metastasis.
-
If requiring steroid treatment for CNS metastases, the patient is on a stable dose <10 mg/day of prednisone or equivalent for at least 2 weeks.
-
Patient does not have leptomeningeal disease
-
Patients with conditions requiring high doses of steroids (>10 mg/day of prednisone or equivalent) or other immunosuppressive medications are excluded. Inhaled or topical steroids are permitted in the absence of active autoimmune disease.
-
Prior treatment with enfortumab vedotin or other MMAE-based antibody-drug conjugates (ADCs).
-
Currently receiving systemic antimicrobial treatment for active infection (viral, bacterial, or fungal) at the time of first dose of enfortumab vedotin. Routine antimicrobial prophylaxis is permitted.
-
Patients with a positive hepatitis B surface antigen and/or antihepatitis B core antibody; patients with a negative polymerase chain reaction (PCR) assay are permitted with either universal prophylaxis or the use of a pre-emptive approach.
-
Active hepatitis C infection or known human immunodeficiency virus (HIV) infection NOTE: Patients who have been curatively treated for hepatitis C infection are permitted if they have documented sustained virologic response of 12 weeks. No HIV testing is required unless mandated by local health authority.
-
Patients with active tuberculosis based on medical history.
-
Documented history of a cerebral vascular event (stroke or transient ischemic attack), unstable angina, myocardial infarction, or cardiac symptoms (including congestive heart failure) consistent with NYHA Class III-IV within 6 months prior to the first dose of enfortumab vedotin.
-
Radiotherapy or major surgery within 2 weeks prior to first dose of study drug. Patient must have recovered adequately from the toxicity and/or complications from the intervention prior to starting study treatment.
-
Patients with active keratitis or corneal ulcerations. Patients with superficial punctate keratitis are allowed if the disorder is being adequately treated in the opinion of the investigator.
-
History of idiopathic pulmonary fibrosis; organizing pneumonia, drug-induced pneumonitis, idiopathic pneumonitis, or evidence of active pneumonitis on screening chest CT scan.
-
Prior allogeneic stem cell or solid organ transplant.
-
Administration of a live, attenuated vaccine within 30 days prior to first dose of study drug. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, BCG, and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (e.g., FluMist®) are live attenuated vaccines and are not allowed.
-
Other underlying medical condition that, in the opinion of the investigator, would impair the ability of the patient to receive or tolerate the planned treatment and follow-up; any known psychiatric or substance abuse disorders that would interfere with cooperating with the requirements of the study.
