Testing Shorter Duration Radiation Therapy Versus the Usual Radiation Therapy in Patients Receiving the Usual Chemotherapy Treatment for Bladder Cancer, ARCHER Study
Purpose
This phase III trial compares the effect of decreased number of radiation (ultra-hypofractionated) treatments to the usual radiation number of treatments (hypofractionation) with standard of care chemotherapy, with cisplatin, gemcitabine or mitomycin and 5-fluorouracil for the treatment of patients with muscle invasive bladder cancer. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a short period of time. Ultra-hypofractionated radiation therapy delivers radiation over an even shorter period of time than hypofractionated radiation therapy. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of tumor cells. Gemcitabine is a chemotherapy drug that blocks the cells from making DNA and may kill tumor cells. Chemotherapy drugs, such as mitomycin-C and 5-fluorouracil (5-FU), 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. Giving ultra-hypofractionated radiation may be equally effective as hypofractionated therapy for patients with muscle invasive bladder cancer.

sterilization (hysterectomy or bilateral oophorectomy) or who is not
postmenopausal
- Absolute neutrophil count (ANC) ≥ 1,500 cells/mm^3
- Platelets ≥ 100,000 cells/mm^3

hemoglobin [Hgb]) ≥ 8.0 g/dl is acceptable)
- Creatinine clearance (CrCL) of ≥ 30 mL/min by the Cockcroft-Gault formula
- Total bilirubin ≤ 2 x institutional upper limit of normal (ULN)
- Aspartate aminotransferase (AST)(serum glutamic oxaloacetic transaminase [SGOT]) and
alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase [SGPT]) ≤ 3 x
institutional ULN
- All adverse events associated with any prior therapy must have resolved to Common
Terminology Criteria for Adverse Events (CTCAE) grade ≤ 3 prior to randomization
- For patients who have completed neoadjuvant therapy, they are eligible if the
pre-neoadjuvant therapy diagnosis (TURBT path) is within 180 days before
randomization
- Must not have had prior pelvic radiation
- New York Heart Association Functional Classification II or better (NYHA Functional
Classification III/IV are not eligible) (Note: Patients with known history or
current symptoms of cardiac disease, or history of treatment with cardiotoxic
agents, should have a clinical risk assessment of cardiac function using the New
York Heart Association Functional Classification.)
- No active infection requiring IV antibiotics
- Patients with hydronephrosis are eligible if they have unilateral hydronephrosis and
kidney function meet criteria specified

Active Comparator Arm I (hypofractionated radiation therapy) |
Patients receive hypofractionated RT QD, Monday to Friday, for 20 treatments in the absence of disease progression or unacceptable toxicity. Patients also receive one of 3 systemic chemotherapy regimens per treating physician's choice: 1) cisplatin IV weekly for 4 weeks; 2) gemcitabine IV on days 1, 4, 8, 11, 15, 18, 22 and 25 or weekly for 4 weeks; or 3) mitomycin-C IV on day 1 and 5 FU, over 120 hours on days 1-5 and 22-26. Treatment is given in the absence of disease progression or unacceptable toxicity. Patients also undergo CT scan and/or MRI or FDG PET throughout the study. In addition, patients may undergo optional blood and urine sample collection throughout the study, as well as an optional biopsy during cystoscopy during follow up. |

Experimental Arm II (Ultrahypofractionated radiation therapy) |
Patients receive ultra-hypofractionated RT QD, no more than twice weekly, for 5 treatments in the absence of disease progression or unacceptable toxicity. Patients also receive one of 3 systemic chemotherapy regimens per treating physician's choice: 1) cisplatin IV weekly for 4 weeks; 2) gemcitabine IV on days 1, 4, 8, 11, 15, 18, 22 and 25 or weekly for 4 weeks; or 3) mitomycin-C IV on day 1 and 5 FU, over 120 hours on days 1-5 and 22-26.

Detailed Description
PRIMARY OBJECTIVE: I. Demonstrate non-inferiority of ultra-hypofractionated (stereotactic body radiation therapy [SBRT]) compared to hypofractionated radiation therapy (RT) with a 10% non-inferiority margin (from 50% to 40%) in the rate of bladder-intact event-free survival (BI-EFS) at 3 years (corresponding to a hazard ratio < 1.32). SECONDARY OBJECTIVES: I. Compare the rates of urinary and bowel toxicity, patient-reported outcomes (PRO), event-free survival (EFS), metastasis-free survival (MFS), and overall survival (OS) between the two treatment arms. II. Compare and evaluate symptomatic adverse events and quality of life measures that are most meaningful to patients. III. Evaluate circulating tumor deoxyribonucleic acid (ctDNA) as a biomarker to determine whether it is predictive of disease recurrence and as a secondary outcome variable. EXPLORATORY OBJECTIVES: I. Evaluate ctDNA, tissue-free minimal residual disease (tfMRD) and urine tumor DNA (utDNA) as biomarkers for predicting recurrence. II. Evaluate tfMRD, obtained at the time of progression, to determine if it captures the presence of disease. OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Patients receive hypofractionated radiation therapy (RT) once daily (QD), Monday to Friday, for 20 treatments in the absence of disease progression or unacceptable toxicity. Patients also receive one of 3 systemic chemotherapy regimens per treating physician's choice: 1) cisplatin intravenously (IV) weekly for 4 weeks; 2) gemcitabine IV on days 1, 4, 8, 11, 15, 18, 22 and 25 or weekly for 4 weeks; or 3) mitomycin-C IV on day 1 and fluorouracil (5 FU), over 120 hours on days 1-5 and 22-26. Treatment is given in the absence of disease progression or unacceptable toxicity. Patients also undergo computed tomography (CT) scan and/or magnetic resonance imaging (MRI) or fluorodeoxyglucose (FDG) positron emission tomography (PET) throughout the study. In addition, patients may undergo optional blood and urine sample collection throughout the study, as well as an optional biopsy during cystoscopy during follow up. ARM II: Patients receive ultra-hypofractionated RT QD, no more than twice weekly, for 5 treatments in the absence of disease progression or unacceptable toxicity. Patients also receive one of 3 systemic chemotherapy regimens per treating physician's choice: 1) cisplatin IV weekly for 4 weeks; 2) gemcitabine IV on days 1, 4, 8, 11, 15, 18, 22 and 25 or weekly for 4 weeks; or 3) mitomycin-C IV on day 1 and 5 FU, over 120 hours on days 1-5 and 22-26. Treatment given in the absence of disease progression or unacceptable toxicity. Patients also undergo CT scan and/or MRI or FDG PET throughout the study. In addition, patients may undergo optional blood and urine sample collection throughout the study, as well as an optional biopsy during cystoscopy during follow up. After completion of study treatment, patients are followed up at week 16, every 3 months for 3 years then every 6 months to year 5.
