A Study of Enfortumab Vedotin Alone or With Other Therapies for Treatment of Urothelial Cancer

Trial Status: Active

This study will test an experimental drug (enfortumab vedotin) alone and with different combinations of anticancer therapies. Pembrolizumab is an immune checkpoint inhibitor (CPI) that is used to treat patients with cancer of the urinary system (urothelial cancer). This type of cancer includes cancer of the bladder, renal pelvis, ureter or urethra. Some parts of the study will look at locally-advanced and metastatic urothelial cancer, which means the cancer has spread to nearby tissues or to other areas of the body. Other parts of the study will look at muscle-invasive bladder cancer (MIBC), which is cancer at an earlier stage that has spread into the muscle wall of the bladder. This study will look at the side effects of enfortumab vedotin alone and with other anticancer therapies. A side effect is a response to a drug that is not part of the treatment effect. This study will also test if the cancer shrinks with the different treatment combinations.

Inclusion Criteria

  • Locally advanced or metastatic urothelial cancer (la/mUC) - Cohorts A, B, D, E, F, G and K.
  • Histologically documented la/mUC, including squamous differentiation or mixed cell types.

  • Muscle Invasive Bladder Cancer (MIBC)- Cohorts H, J and L.
  • Histologically confirmed MIBC with predominant >50% urothelial histology:Cohorts H and J: Clinical stage cT2-T4aN0M0; Cohort L: Clinical stage cT2-T4aN0M0 or cT1-T4aN1M0: Participants with pT1 disease are eligible only if they have N1 disease on imaging. Mixed cell types are eligible if urothelial cancer is predominant (>50%); Participants with plasmacytoid and/or neuroendocrine tumors are ineligible regardless of component percentage.
  • Must be cisplatin-ineligible.
  • Cohort-specific eligibility: Cohort J, H, and L: No prior systemic treatment, chemoradiation, or radiation therapy for MIBC. May have received prior intravesical Bacillus Calmette-Guerin (BCG) or intravesical chemotherapy for non-MIBC; Cohort J: Eligible for pembrolizumab.
  • ECOG performance status of 0, 1, or 2.
  • Anticipated life expectancy of ≥3 months.
  • Tumor samples with an associated pathology report from the diagnostic transurethral resection of a bladder tumor done 90 days prior to the first dose of study treatment must be available prior to enrollment and determined to be sufficient for pathology review and biomarker analysis.
  • Participants must be deemed eligible for radical cystectomy and pelvic lymph node dissection.

Exclusion Criteria

  • la/mUC - Cohorts A, B, D, E, F, G, and K
  • Received any prior treatment with a PD-1 inhibitor, PD-L1 inhibitor, or PD-L2 inhibitor, except Cohort F.
  • Received any prior treatment with stimulatory or co-inhibitory T-cell receptor agents, such as CD137 agonists, OX-40 agonists, or cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) inhibitors (except Cohort F).
  • Ongoing sensory or motor neuropathy Grade 2 or higher.
  • Active central nervous system (CNS) metastases.
  • Ongoing clinically significant toxicity (Grade 2 or greater) associated with prior treatment (including radiotherapy or surgery).

  • Evidence of nodal or metastatic disease on imaging per local assessment. Participants in Cohort L with pT1 disease may not have ≥N2 nodal disease on imaging.
  • Ongoing sensory or motor neuropathy Grade 2 or higher.
  • Conditions requiring high doses of steroids or other immunosuppressive medications.
  • Prior treatment with enfortumab vedotin or other MMAE-based ADCs for urothelial cancer.
  • History of another malignancy within 3 years before first dose of study drug.
