Bintrafusp Alfa (M7824) and PDS01ADC Alone and in Combination With Stereotactic Body Radiation Therapy (SBRT) in Adults With Metastatic Non-Prostate Genitourinary Malignancies

Recruiting now · Phase 1

Conditions studied: Urothelial Cancer, Bladder Cancer, Genitourinary Cancer, Urogenital Neoplasms, Urogenital Cancer

In brief

Background: Genitourinary cancers are some of the most common types of cancer. They are lethal when they spread. The drug M7824 blocks the paths that cancer cells use to stop the immune system from fighting cancer. The drug PDS01ADC triggers the immune system to fight cancer. Researchers want to learn if these drugs can help fight these cancers when given with and without Stereotactic Body Radiation Therapy (SBRT) radiation. Objective: To learn if M7824 and PDS01ADC, with or without SBRT, can help the immune system to fight cancer better. Eligibility: People 18 and older with cancer that started in the bladder, kidneys, or other genitourinary organs (but not the prostate) and has spread to other parts of the body. Design: Participants will be screened with: medical history physical exam ability to do their normal activities blood tests urine tests electrocardiogram body scans. Participants will give a tumor sample or have a tumor biopsy. Screening tests will be repeated during the study. Participants will get PDS01ADC . It is injected under the skin every 4 weeks. They will also get M7824 through an intravenous (IV) infusion every 2 weeks. For this, a small plastic tube is put into a vein in the arm. They will get these drugs in 28-day cycles until they leave the study. They may have SBRT. Participants will give tissue and saliva samples. Participants will have a follow-up visit 30 days after treatment ends. Then they will get phone calls or emails every 12 weeks indefinitely.

You may not qualify if…

• History of allergic reactions attributed to compounds of similar chemical or biologic composition to M7824 and/or PDS01ADC investigational agents used in the study.
• Uncontrolled intercurrent illness including, but not limited to, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements. Participants with a history of bleeding diathesis or recent clinically significant bleeding events considered by the Investigator as high risk for investigational drug treatment are also excluded with the exception of hematuria.
• Participants unwilling to accept blood products as medically indicated
• Pregnant individuals are excluded from this study because M7824 and/or PDS01ADC are agents with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with M7824 and/or PDS01ADC, nursing should be discontinued if the nursing individual is treated with these agents.
• Participants with any active or recent history of a known or suspected autoimmune disease or recent history of a syndrome that required treatment with either systemic corticosteroids (> 10 mg daily prednisone equivalent) or immunosuppressive medications. Inhaled steroids and adrenal replacement steroid doses up to 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease. Participants with inflammatory bowel disease that have been in remission for at least 5 years whether or not they are currently on immunosuppressive therapy provided that they are not on systemic corticosteroids (> 10mg daily prednisone equivalent) are eligible.
• Participants with any active or recent history of inflammatory bowel disease, active lupus or scleroderma or other medical conditions (i.e., pneumonits with planned SBRT to lung lesion) or genetic radiosensitivity syndromes will be excluded from the study unless deemed eligible by Principal Investigator because these diseases make the participant unsafe or ineligible for radiation therapy with SBRT.
• Participants with a "currently active" second malignancy other than non-melanoma skin cancers or cervical carcinoma in situ or incidental organ-confined prostate cancer found on cystoprostatectomy (provided that the following criteria are met: Stage T2N0M0 or lower; Gleason score <= 3+4, Prostate-Specific Antigen (PSA) undetectable). Participants 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.
• Participants having tumor lesion(s) in the liver or chest which are 10 cm or larger.
