Enfortumab Vedotin with Concurrent Radiation Therapy for the Treatment of Locally Advanced Bladder Cancer, CONSOLIDATE Trial
This phase I/II trial studies the side effects and best dose of enfortumab vedotin when given at the same time as (concurrent) radiation therapy (RT) and to see how well it works in treating bladder cancer that has spread to nearby tissue or lymph nodes (locally advanced). Enfortumab vedotin is a monoclonal antibody, enfortumab, linked to an anticancer drug called vedotin. It works by helping the immune system to slow or stop the growth of cancer cells. Enfortumab attaches to a protein called nectin-4 on cancer cells in a targeted way and delivers vedotin to kill them. It is a type of antibody-drug conjugate. RT uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Giving enfortumab vedotin concurrently with RT may work better in treating locally advanced bladder cancer.

- PRIOR TO CORE ENROLLMENT: Female patients must consistently use highly effective methods of birth control starting at screening and continue throughout the study period and for at least 6 months after radiation completion
- FOLLOWING CORE ENROLLMENT: Candidate for definitive local radiation therapy to active disease per the discretion of the treating physicians
Exclusion Criteria
- PRIOR TO CORE ENROLLMENT: Has a diagnosis of active scleroderma, lupus, ulcerative colitis, or other rheumatologic disease which in the opinion of the treating radiation oncologist precludes safe radiation therapy
- PRIOR TO CORE ENROLLMENT: Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial as determined by the treating physician and/or member of the study team
- PRIOR TO CORE ENROLLMENT: Distant metastatic disease beyond lymph node metastases, which by the discretion of the treating physician cannot be treated definitively in a radiation field
- PRIOR TO CORE ENROLLMENT: Has history of prior pelvic radiation therapy
- PRIOR TO CORE ENROLLMENT: Has ongoing clinically significant toxicity (grade 2 or higher with exception of alopecia) associated with prior systemic therapy
- PRIOR TO CORE ENROLLMENT: History of uncontrolled diabetes mellitus within 3 months of enrollment. Uncontrolled diabetes is defined as hemoglobin A1c (HbA1c) ≥ 8% or HbA1c between 7 and < 8% with associated diabetes symptoms (polyuria or polydipsia) that are not otherwise explained

Testing is recommended if deemed appropriate based on clinical factors and/or laboratory abnormalities prior to study enrollment
- PRIOR TO CORE ENROLLMENT: Has a known history of human immunodeficiency virus (HIV) infection. Testing is recommended if deemed appropriate based on clinical factors and/or laboratory abnormalities prior to study enrollment
- PRIOR TO CORE ENROLLMENT: Has 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. Physiologic replacement doses of corticosteroids are permitted for subjects with adrenal insufficiency
- PRIOR TO CORE ENROLLMENT: Has a history of idiopathic pulmonary fibrosis, organizing pneumonia, drug induced pneumonitis, idiopathic pneumonitis, or evidence of active pneumonitis on screening chest CT scan
- PRIOR TO CORE ENROLLMENT: Has received a prior allogeneic stem cell or solid organ transplant
- PRIOR TO CORE ENROLLMENT: Has active tuberculosis
- FOLLOWING CORE ENROLLMENT: Is pregnant or expecting to conceive within the projected duration of the trial at the screening visit * Female subject of childbearing potential should have a negative urine or serum pregnancy within 6 weeks prior to study registration up to the first fraction of radiation * Note: If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required

PRIMARY OBJECTIVES:
I. To estimate progression free survival for concurrent enfortumab vedotin with RT in locally advanced muscle invasive bladder cancer (MIBC).
II. To evaluate the safety/tolerability of enfortumab vedotin with RT in patients with locally advanced MIBC.
III. To evaluate global health-related quality of life (HRQOL) using EuroQol-5 Dimension-5 Level (EQ-5D-5L), European Organization for Research and Treatment of Cancer Muscle Invasive Bladder Cancer (EORTC MIBC) module, and Expanded Prostate Cancer Index Composite (EPIC) bowel domain surveys.
SECONDARY OBJECTIVES:
I. To estimate the overall survival at 12 months after study enrollment.
II. To estimate the metastasis free survival at 12 months after study enrollment.
III. To determine the treatment related toxicities associated with enfortumab vedotin with RT as part of definitive local therapy for advanced MIBC.
IV. To estimate the freedom from genitourinary (GU) events after enfortumab vedotin with RT.
EXPLORATORY OBJECTIVE:
I. To determine the association of translational biomarkers including peripheral blood tumor markers and urine tumor markers with patient outcomes.
OUTLINE: This is a phase I, dose-escalation study of enfortumab vedotin followed by a phase II study.
Patients receive enfortumab vedotin intravenously (IV) over 1-2 hours on days 1 and 8 of every cycle and undergo RT with either intensity modulated radiation (IMRT), proton RT, 3-dimensional (3D) conformal RT, or magnetic resonance imaging (MRI) linac RT once daily (QD) for 20 days over 4-5 weeks. Cycles repeat every 28 days, while receiving concurrent RT, in the absence of disease progression or unacceptable toxicity. Patients may receive maintenance enfortumab vedotin once RT is completed at the discretion of the treating physician. Patients undergo blood sample collection, cystoscopy, and computed tomography (CT) or MRI throughout the study. Patients may also undergo a transurethral resection of bladder tumor (TURBT) during screening.
After completion of study treatment, patients are followed up at months 3, 6, 12, 18, and 24 and then yearly for up to 5 years.
