Primary Outcome 1 - Timeframe: N/A


  • Urothelial Cancer


Inclusion Criteria:
* Patients must be at least 18-years-old

- * ECOG performance status 0-2

- * Patients must have pathology-proven metastatic urothelial carcinoma, with tissue sampling of at least the primary tumor. Tissue sampling of each presumed metastatic site is not necessary, provided that the patient already has a confirmed diagnosis of urothelial cancer.

- * Patients must be on immune checkpoint inhibitor therapy with radiographic scans to verify oligo-progression of at least one and ≤ 6 sites of disease per RECIST 1.1.
* Any of the currently FDA-approved PD-1/PD-L1 inhibitors are allowed. These include pembrolizumab, nivolumab, atezolizumab, avelumab, and durvalumab.

- * At least 1 metastatic lesion must show stable disease, partial response or complete response per RECIST 1.1.

- * Patients must be able to understand and willing to sign written informed consent.

- * Patients must have acceptable tolerability of ongoing therapy as decided by the treating medical oncologist.

- * Patients must have a desire to continue ongoing therapy.

- * Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 90 days following completion of therapy.

- * A female of child-bearing potential is any woman (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria:
* Has not undergone a hysterectomy or bilateral oophorectomy, or has not been naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months).

- * Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.
Exclusion Criteria:
* Inability to receive further immune checkpoint inhibitor therapy

- * Anticipated survival of fewer than 12 weeks

- * Daily steroid requirement of > 10 mg prednisone or prednisone-equivalent. Steroid replacement therapy for adrenal insufficiency is permitted.

- * Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that, in the opinion of the investigator, would limit compliance with study requirements.

- * Subjects must not be pregnant or nursing due to the potential for congenital abnormalities and the potential of this regimen to harm nursing infants.
