Brief Summary:

Background:

Metastatic urothelial carcinoma is lethal and has no cure. Response rates to current treatments are modest. Researchers want to find new strategies to treat the disease. In this study, they will test a drug called Bintrafusp alfa (M7824). The drug is a new immunotherapy that blocks the pathways that cancer cells use to stop the immune system from fighting cancer.

Objective:

To learn if M7824 can help the immune system's ability to fight urothelial cancer.

Eligibility:

People age 18 and older who have urothelial cancer that has spread to other parts of their body and they have been previously treated with chemotherapy or immunotherapy

Design:

Participants will be screened with a medical history and physical exam. They will have blood and urine tests. They will have imaging scans. They will have an electrocardiogram to measure heart function. Their ability to perform their normal activities will be evaluated. They may have a tumor biopsy. They will take a pregnancy test if needed.

Participants will repeat some of the screening tests during the study.

Treatment will be given in a series of 28-day cycles. Participants will get M7824 once every 2 weeks. It is given through an intravenous infusion. For this, a small plastic tube is put into an arm vein. They will get M7824 until their disease gets worse, they have unacceptable side effects, or they decide to stop treatment.

Participants will have a follow-up visit 30 days after treatment ends. Then they will be followed every 12 weeks in the clinic or by telephone/email. Follow-up will last indefinitely.

Official Title: A Phase II Study of Bintrafusp Alfa (M7824) in Checkpoint Inhibitor Naive and Refractory Subjects With Urothelial Carcinoma
Actual Study Start Date : October 26, 2020
Actual Primary Completion Date : January 19, 2021
Actual Study Completion Date : October 13, 2021


Arm Intervention/treatment
Experimental: 1/Arm 1-Treatment with Bintrafusp alfa (M7824)
Treatment with Bintrafusp alfa (M7824)
Drug: Bintrafusp alfa (M7824)
1200 mg administered intravenous (IV) every two weeks
Other Name: M7824




Primary Outcome Measures :
  1. Proportion of Participants With an Objective Response Rate (ORR) [ Time Frame: From time measurement criteria are met for CR or PR (whichever is first recorded) until the first date that recurrent or progressive disease is objectively documented, approximately 3 months. ]
    The proportion of evaluable patients with objective response rate (ORR) defined as a partial response (PR) or complete response (CR) at the end of treatment with Bintrafusp alfa (M7824). Response was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST)v1.1. Partial response is at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum of diameters. Complete response is disappearance of all target lesions.


Secondary Outcome Measures :
  1. Number of Participants With Toxicity Grade >1 [ Time Frame: Until confirmed progression, unacceptable toxicity or trial withdrawal, approximately 4 months and 3 days for cohort 1B and 11 months and 17 days for cohort B. ]
    The number of participants with toxicity grade >1 assessed by the Common Terminology Criteria for Adverse Events (CTCAE)v5.0. Grade 1 is mild, Grade 2 is moderate, Grade 3 is severe, Grade 4 is life-threatening, and Grade 5 is death related to adverse events.

  2. Number of Participants With Progression Free Survival (PFS) [ Time Frame: From start of treatment to time of progression or death, approximately 6 weeks (first scheduled restaging scan) ]
    PFS is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first. Progression was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST)v1.1 and is defined as at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study; and the appearance of one or more new lesions.

  3. Number of Participants That Survived [ Time Frame: Time from treatment to the date of death from any cause, approximately 11 months. ]
    Here is the number of participants that survived.


Other Outcome Measures:
  1. Number of Participants With Serious and/or Non-serious Adverse Events Assessed by the Common Terminology Criteria for Adverse Events (CTCAE v5.0). [ Time Frame: Date treatment consent signed to date off study, approximately 4 months and 3 days for cohort 1B and 11 months and 17 days for cohort B. ]
    Here is the number of participants with serious and/or non-serious adverse events assessed by the Common Terminology Criteria for Adverse Events (CTCAE v5.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned.

Patients are not considered to have a currently active malignancy if they have completed therapy and are free of disease for >= 2 years and currently do not require systemic therapy.
  • Patients who have received or will receive a live vaccine within 30 days prior to the first administration of study intervention. Seasonal flu vaccines that do not contain a live virus are permitted. Locally approved COVID vaccines are permitted.
