Eligibility Criteria  ICMJE

Inclusion Criteria:

  • Written informed consent and HIPAA authorization for release of personal health information prior to registration. NOTE: HIPAA authorization may be included in the informed consent or obtained separately.
  • ECOG Performance Status of 0 or 1 within 14 days prior to registration.
  • Histologically or cytologically documented urothelial cancer. Locally advanced (T4b, any N; or any T, N 2-3) or metastatic disease (M1, Stage IV) (also termed TCC or UCC of the urinary tract; including renal pelvis, ureters, urinary bladder, and urethra) Subjects with mixed histologies are eligible provided that the predominant component is urothelial cancer. Locally advanced bladder cancer must be inoperable on the basis of involvement of pelvic sidewall or adjacent viscera (clinical Stage T4b) or bulky nodal metastasis (N2-N3).
  • Representative formalin-fixed paraffin-embedded (FFPE) tumor specimens in paraffin blocks (blocks preferred) or at least 15 unstained slides. If archival tissue is not available and the subject is undergoing a standard of care biopsy, tissue from the biopsy is required to be submitted for correlative analyses. Subjects without adequate baseline tumor tissue may be considered for enrollment on a case by case basis after discussion with the sponsor-investigator.
  • Measurable disease according to RECIST 1.1 within 28 days prior to registration. At least 1 lesion, not previously irradiated, that can be accurately measured at baseline as ≥10 mm in the longest diameter (except lymph nodes, which must have short axis ≥15 mm) with computed tomography (CT) (preferred) or magnetic resonance imaging (MRI) scans, preferably with IV contrast, and that is suitable for accurate repeated measurements as per RECIST 1.1 guidelines; lesions in a previously irradiated field can be used as a measurable disease provided that there has been demonstrated progression in the lesion.
  • A subject with prior brain metastasis may be considered if they have completed their treatment for brain metastasis at least 4 weeks prior to study registration, have been off of corticosteroids for ≥ 2 weeks, and are asymptomatic
  • Subjects must have progressed despite prior treatment with anti-PD-1/PD-L1 antibody therapy. In addition, subjects must meet the following criteria:

    • Subjects must not have progressed within 2 months of starting prior anti-PD-1/PD-L1 antibody therapy.
    • Subjects must have received at least 1 line of prior systemic therapy
    • Must not have experienced a toxicity that led to permanent discontinuation of prior immunotherapy.
    • All AEs while receiving prior immunotherapy must have completely resolved or resolved to baseline prior to screening for this study with the exception of endocrine related AEs that are stable on replacement therapy (e.g., steroids, thyroid hormone) which may be considered eligible but must be discussed with the sponsor-investigator.
    • Must not have experienced a ≥ Grade 3 immune related AE or an immune related neurologic (neuro-muscular) or ocular AE of any grade while receiving prior immunotherapy. NOTE: Subjects with endocrine AE of ≤ Grade 2 are permitted to enroll if they are stably maintained on appropriate replacement therapy and are asymptomatic. Must not have required the use of additional immunosuppression other than corticosteroids for the management of an AE, not have experienced recurrence of an AE if re-challenged, and not currently require maintenance doses of > 10 mg prednisone or equivalent per day.
    • Patients with Gr 3 AST/ALT elevation < 8 fold that resolved with steroids without additional immunosuppression can be included (Patients who experienced Hy's law on PD-1/L1 therapy will be excluded)
  • Prior cancer treatment must be completed at least 28 days or 5 half-lives (whichever is shorter) prior to first dose of study drug. Subjects must have recovered from all reversible acute toxic effects of the regimen (other than alopecia) to ≤ Grade 1 or baseline.

  • Females of childbearing potential who are sexually active with a non-sterilized male partner must be willing to abstain from heterosexual activity or to use 1 highly of effective method of contraception from the time of informed consent until 90 days after the last dose of tremelimumab. Non-sterilized male partners of a female patient must use male condom plus spermicide throughout this period. See Table 2 for acceptable contraceptive methods.
  • Non-sterilized males who are sexually active with a female partner of childbearing potential must use a male condom plus spermicide from screening through 90 days after receipt of the final dose of tremelimumab. Female partners (of childbearing potential) of male subjects must also use a highly effective method of contraception throughout this period
