Brief Summary

This is a phase II trial designed to estimate the activity of single agent tremelimumab in subjects with metastatic urothelial cancer with disease progression despite prior treatment with PD-1/PD-L1 blockade. The primary endpoint is objective response rate and the study will employ a Simon's 2-stage design.

Primary Outcomes:

Primary Outcome 1 - Measure: Objective Response Rate

Primary Outcome 1 - Time Frame: 24 months

Condition:

  • Urothelial Carcinoma

Eligibility

Criteria:
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.
r/> - 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.

- Demonstrate adequate organ function as defined in the table below. All screening labs
to be obtained within 14 days prior to registration.

- Absolute Neutrophil Count (ANC) ≥ 1500/mm3

- Hemoglobin (Hgb) ≥ 9 g/dL

- Renal

- Calculated creatinine clearance ≥ 30 cc/min OR

- Creatinine ≤ 1.5

- Bilirubin ≤ 1.5 × upper limit of normal (ULN); This will not apply to

- Aspartate aminotransferase (AST) ≤ 2.5 × ULN (≤ 5 x ULN for subjects with hepatic
metastases

- Alanine aminotransferase (ALT) ≤ 2.5 × ULN (≤ 5 x ULN for subjects with hepatic
metastases

- Evidence of postmenopausal status or negative urinary or serum pregnancy test for
female premenopausal subjects. Women will be considered postmenopausal if they have
been amenorrheic for 12 months without an alternative medical cause. The following
age-specific requirements apply:

- 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

Exclusion Criteria:

- Pregnant or breastfeeding (NOTE: breast milk cannot be stored for future use while the
mother is being treated on study).

- Known additional malignancy that is active and/or progressive requiring treatment.
Patients with incidental histologic findings of prostate cancer (tumor/node/metastasis
stage of T1a or T1b or prostate-specific antigen <10) who have not received hormonal
treatment may be included, pending a discussion with the sponsor-investigator

- Treatment with any investigational drug within 28 days prior to registration.

- Prior treatment with an anti-CTLA-4 antibody

- Any unresolved toxicity National Cancer Institute (NCI) CTCAE Version 4.03 Grade ≥ 2

laboratory values defined in the inclusion criteria.

- Subjects with Grade ≥ 2 neuropathy will be evaluated on a case-by-case basis
after consultation with the Sponsor Investigator

- Subjects with irreversible toxicity not reasonably expected to be exacerbated by
treatment with tremelimumab (e.g., hearing loss) may be included after
consultation with the sponsor-investigator

- Any concurrent chemotherapy, investigational product, biologic, or hormonal therapy
for cancer treatment. Concurrent use of hormonal therapy for non-cancer related
conditions (e.g., hormone replacement therapy) is acceptable. Note: Local treatment of
isolated lesions, excluding target lesions, for palliative intent is acceptable (e.g.,
local surgery or radiotherapy)

- Radiation therapy within 14 days of first dose of study drug

- Major surgical procedure within 28 days prior to first dose of study treatment

- History of allogeneic organ transplantation that requires use of immunosuppressive
agents

- Active or prior documented autoimmune of inflammatory disorders (including but not
limited to inflammatory bowel disease [eg, colitis or Crohn's disease], diverticulitis
[with the exception of diverticulosis], systemic lupus erythematosus, Sarcoidosis
syndrome [granulomatosis with polyangiitis], Graves' disease, rheumatoid arthritis,
hypophysitis, uveitis, etc). The following are exceptions to this criterion:

- Subjects with vitiligo

- Subjects with hypothyroidism (e.g., following Hashimoto syndrome) stable on
hormone replacement

- Any chronic skin condition that does not require systemic therapy

- Subjects without active disease in the last5 years may be considered for
enrollment after discussion with the sponsor-investigator

- Subjects with celiac disease controlled by diet alone may be considered for
enrollment after discussion with the sponsor-investigator

- QT interval corrected for heart rate using Fridericia's formula (QTcF) ≥470 ms

results and a mean QTcF <470 ms calculated from 3 ECGs obtained over a brief period
(eg, 30 minutes)

- Past medical history of Interstitial Lung Disease (ILD), drug-induced ILD, radiation
pneumonitis which required steroid treatment, or any evidence of clinically active
interstitial lung disease.
