About
This phase I trial studies the side effects and best dose of belinostat when given together with durvalumab in treating patients with urothelial cancer that has spread to other places in the body (metastatic) or cannot be removed by surgery (unresectable) and has spread to nearby tissue or lymph nodes (locally advanced). Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Belinostat is a potential anti-cancer drug, known as a histone deacetylase (HDAC) inhibitor, which means that belinostat stops the activity of HDAC enzymes (an enzyme is a protein that in small amounts can speed up a biological reaction). HDAC enzymes play an important role in cell growth and cell death. Giving durvalumab and belinostat may improve the body's ability to fight cancer.
Full description
PRIMARY OBJECTIVES:
I. To assess the recommended phase 2 dose of belinostat in combination with tremelimumab and durvalumab or belinostat in combination with durvalumab alone in advanced urothelial carcinoma. (Phase 1A) II. To assess the ongoing safety of belinostat in combination with durvalumab in patients with advanced urothelial carcinoma. (Phase 1B)
SECONDARY OBJECTIVES:
I. To assess the efficacy of belinostat in combination with tremelimumab and durvalumab or belinostat in combination with durvalumab in patients with advanced urothelial carcinoma.
EXPLORATORY OBJECTIVES:
I. To assess the mechanism of action of belinostat in combination with tremelimumab and durvalumab or belinostat in combination with durvalumab.
II. To explore possible mechanisms of treatment resistance. III. Determine the feasibility of establishing patient-derived xenografts from tumor cells collected from enrolled subjects at baseline, and progression to better explore mechanisms of response and resistance. IIII. To explore possible biomarkers predictive of treatment benefit.
OUTLINE: This is a dose-escalation study of belinostat.
Patients receive durvalumab intravenously (IV) over 30 minutes on day 1. Patients also receive tremelimumab IV over 60 minutes on day 1 of cycle 1. Beginning cycle 2, patients receive belinostat IV over 30 minutes on days 1-5. Treatment repeats every 21 days for 7 cycles in the absence of disease progression or unacceptable toxicity. Patients then receive durvalumab IV over 30 minutes on day 1. Treatment repeats every 28 days for up to 24 cycles in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 1 year and then every 6 months for 2 years.

Estimated life expectancy of at least 12 weeks
Exclusion criteria

Subject has received systemic antineoplastic therapy (including unconjugated therapeutic antibodies and toxin immunoconjugates) or any investigational therapy =< 14 days or within 5 half-lives before starting study treatment, whichever is shorter
Prior treatment with durvalumab
Subject has received radiotherapy =< 14 days before the first dose of study treatment. Localized radiation therapy for the treatment of symptomatic bone metastasis is allowed during that timeframe
Subjects who have undergone major surgery =< 3 weeks before starting study drug or who have not fully recovered from major surgery
Known additional malignancy that is active and/or progressive and requiring treatment.
Known brain metastases or cranial epidural disease
Current evidence of uncontrolled, clinically significant intercurrent illness including, but not limited to, the following conditions:
Cardiovascular disorders:
Congestive heart failure New York Heart Association Class 3 or 4, unstable angina pectoris, serious cardiac arrhythmias
Stroke (including transient ischemic attack [TIA]), myocardial infarction (MI), or other ischemic events, or thromboembolic event (e.g., deep venous thrombosis, pulmonary embolism) within 3 months before the first dose
Uncontrolled hypertension defined as a sustained systolic blood pressure >= 160 mmHg or a diastolic blood pressure >= 100 mmHg despite optimal management
Adrenal insufficiency
Interstitial lung disease (ILD)
Subjects with congenital long QT syndrome
Patients currently on or who will require valproic acid for any medical condition during the study
Active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease [e.g., colitis or Crohn's disease], diverticulitis [except for diverticulosis], systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome [granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc.]). The following are exceptions to this criterion:
