About
This phase II trial compares the use of pembrolizumab and radiation therapy to chemotherapy with cisplatin, gemcitabine, 5-fluorouracil or mitomycin-C and radiation therapy for the treatment of non-muscle invasive bladder cancer. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as cisplatin, gemcitabine, 5-fluorouracil or mitomycin-C, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Giving pembrolizumab with radiation may kill more tumor cells than chemotherapy with radiation therapy in patients with non-muscle invasive bladder cancer.
Full description
PRIMARY OBJECTIVE:
I. To compare bladder-intact event-free survival.
SECONDARY OBJECTIVES:
I. To assess complete response by cystoscopy at 6 months. II. To assess disease-free survival. III. To assess local-regional control. IV. To assess metastasis-free survival. V. To assess overall survival. VI. To assess quality of life using European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) and the Bladder Cancer Index at 18 months.
VII. To assess Common Terminology Criteria for Adverse Events (CTCAE) adverse events (both acute and late).
EXPLORATORY OBJECTIVES:
I. To assess fatigue using the Patient Reported Outcomes Measurement Information System Fatigue-4A (PROMIS-Fatigue-4a).
II. To assess quality adjusted survival using European Quality of Life Five Dimension Five Level Scale (EQ-5D-5L).
III. To assess cumulative quality of life using EORTC QLC-C30 and Bladder Cancer Index at 24 months.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM 1: Patients receive one of the following chemotherapy regimens per physicians choice: 1) cisplatin intravenously (IV) once per week for 4 weeks, 2) gemcitabine IV on days 1, 4, 8, 11, 15, 18, 22, and 25, or 3) mitomycin IV on day 1 and 5-fluorouracil IV continuously over 120 hours on days 1-5 and 16-20. Patients receiving cisplatin or gemcitabine continue chemotherapy for 6 weeks if they are receiving radiation according to the standard hypofractionated radiation schedule. Starting on day 1, patients also receive radiation therapy for 20, 32, or 36 treatments over 4-7 weeks. Treatment is given in the absence of disease progression or unacceptable toxicity. Patients also undergo computed tomography (CT)/magnetic resonance imaging (MRI) and blood sample collection throughout the study. Patients may also undergo optional urine sample collection on study.
ARM 2: Patients receive pembrolizumab IV over 25-40 minutes on day 1 of each cycle. Cycles repeat every 6 weeks for 9 cycles in the absence of disease progression or unacceptable toxicity. Starting on day 1, patients also receive radiation therapy for 20, 32, or 36 treatments over 4-7 weeks. Treatment is given in the absence of disease progression or unacceptable toxicity. Patients also undergo CT/MRI and blood sample collection throughout the study. Patients may also undergo optional urine sample collection on study.
After completion of study treatment, patients are followed up every 3 months for 2 years, then every 6 months for 3 years and then annually for 5 years.

Inclusion and exclusion criteria
Inclusion Criteria:
-
Pathologically (histologically) proven diagnosis of T1 high-grade non-muscle invasive urothelial carcinoma of the bladder without radiographic evidence of regional nodal disease or metastatic disease (N0, M0) on CT, MRI, or positron emission tomography (PET)/CT scan who would otherwise be treated with cystectomy off-trial. Patients should have cystectomy recommended disease but do not need to be medically operable for a cystectomy to be eligible for the trial.
- NOTE: Patients with nodal disease ≥ 1 cm on short-axis or with suspicious nodes that are PET-avid of any size are not eligible
-
High grade T1 disease history that must meet at least ONE of the three criteria below:
- Histologically confirmed recurrence with high-grade T1 urothelial carcinoma (+/- focal carcinoma in situ [CIS]) in the bladder following initial transurethral resection of bladder tumor (TURBT) and at least one induction course of intravesical therapy. Adequate induction course is defined as ≥ 5 doses of intravesical Bacillus Calmette-Guerin (BCG) or intravesical chemotherapy when BCG is not available.
- T1 with pathologic high-risk features (lymphovascular invasion [LVI] or variant histology of micropapillary, sarcomatoid, or plasmacytoid features) post initial TURBT. (No prior intravesical therapy required)
- Persistent high-grade T1 urothelial carcinoma at repeat TURBT (+/- focal CIS) in the bladder. (No prior intravesical therapy required)
-
Restaging TURBT must be performed and must meet ALL of the following criteria below:
-
If there is absence of muscularis propria in the initial TURBT, there must be uninvolved muscularis propria in the restaging TURBT.
-
All grossly visible papillary tumors must be removed
- Note: If the restaging TURBT is performed outside of the enrolling institution, an office cystoscopy should be performed by a Urologist who will be following the patient as part of the clinical trial
-
-
No pure squamous cell carcinoma or adenocarcinoma of the bladder
-
No neuroendocrine (small or large cell) features
-
No diffuse carcinoma in situ determined on cystoscopy and biopsy (i.e. extensive carcinoma in situ that is not just tumor-associated CIS in the opinion of the site investigator)
-
No prostatic urethral involvement
-
