简要总结
Background:
A most common liver cancer in adults is hepatocellular carcinoma. Other kinds of liver cancer happen when colorectal or pancreatic cancer spreads to the liver. Researchers want to study if a combination of drugs helps people with these cancers. The drugs are nivolumab, tadalafil, and vancomycin.
Objective:
To investigate if nivolumab given with tadalafil and vancomycin causes liver cancer to shrink.
Eligibility:
Adults ages 18 years and older with hepatocellular carcinoma or metastases to the liver from colorectal or pancreatic cancer for which standard treatment has not worked
Design:
Participants will be screened with:
Medical and cancer history
Review of symptoms and ability to perform normal activities
Physical exam
Heart test. Some participants may meet with a cardiologist and/or have another heart test.
Scan of the chest, abdomen, and pelvis
Blood and urine tests
Tumor sample review. This can be from a previous procedure.
Participants will receive the study drugs in 4-week cycles. In each cycle participants will:
Get nivolumab through a small plastic tube in the arm on Day 1.
Take tadalafil by mouth 1 time every day.
Take vancomycin by mouth 4 times a day. They will take it every day for weeks 1 3, then not take it for week 4.
Complete a medicine diary of dates, times, missed doses and symptoms.
Throughout the study, participants will repeat screening tests and will give stool samples or rectal swabs.
After their last cycle, participants will have 3 follow-up visits over 3 months. Then they will be contacted every 6 months by phone or email and asked about their general well-being.

详细描述
Background:
- Current treatment options for patients with liver cancers, including hepatocellular carcinoma (HCC) and advanced liver cancers are limited and take no account of the known biological and genetic heterogeneity in these diseases. Median survival for advanced disease remains poor at approximately 1 year.
- Nivolumab is a fully human monoclonal immunoglobulin G4 (IgG4) antibody that is specific for human programmed death-1 (PD-1, cluster of differentiation 279 [CD279]) cell surface membrane receptor. Nivolumab has been approved by the Food and Drug Administration (FDA) for the treatment of HCC and other solid tumors.
- Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor which have been approved by the FDA for the treatment of pulmonary arterial hypertension, benign prostatic hyperplasia and erectile dysfunction, with a relative safe clinical profile. PDE5 inhibitors have been examined in multiple malignancies and cancer cell lines for their direct anticancer activities, for their
efficacy as chemo-sensitizers and for cancer chemoprevention.
- Oral vancomycin is antibiotic that has effect on altering gut commensal bacteria subsequently inducing a liver-selective anti-tumor effect.
- The aim of the study is to evaluate whether the immunomodulatory effect induced by PDE5 inhibitor and oral vancomycin can be enhanced by immune checkpoint inhibition in advanced liver cancer.

- •The effects of nivolumab on the developing human fetus are unknown.

- •Therapy with antibiotics within 30 days prior to enrollment.
- •Therapy with nitrates, alpha-blockers, or cytochrome P450 (CYP3A4) inhibitors within 7- days prior to enrollment and for whom stopping is unsafe and/or a safe substitute is not medically recommended.

- •The patient must not be currently on a corticosteroid dose greater than physiologic replacement dosing defined as 10 mg of cortisone per day or its equivalent.
- •For PDAC patients with liver metastases, primary PDAC has not been resected (unless the primary is in the tail of the pancreas).
- •Patients with known brain metastases will be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.
- •Have signs of liver failure, e.g., clinical significant ascites, encephalopathy, or variceal bleeding within 6 months prior to enrollment.
- •Prior major liver resection: remnant liver <50% of the initial liver volume. Patients with a biliary stent can be included.
- •Patients with active autoimmune disease or history of autoimmune disease that might recur, which may affect vital organ function or require immune suppressive treatment including systemic corticosteroids. These include but are not limited to patients with a history of immune related neurologic disease, multiple sclerosis, autoimmune (demyelinating) neuropathy, Guillain-Barre syndrome or Chronic Inflammatory Demyelinating Polyneuropathy (CIDP), myasthenia gravis; systemic autoimmune disease such as Systemic lupus erythematosus (SLE), connective tissue diseases, scleroderma, inflammatory bowel disease (IBD), Crohn's, ulcerative colitis, hepatitis; and patients with a history of toxic epidermal necrolysis (TEN), Stevens-Johnson syndrome, or phospholipid syndrome. Such diseases should be excluded because of the risk of recurrence or exacerbation of disease.
- •Of note, patients with vitiligo, endocrine deficiencies including thyroiditis managed with replacement hormones including physiologic corticosteroids are eligible. Patients with rheumatoid arthritis and other arthropathies, Sjogren's syndrome and psoriasis controlled with topical medication and patients with positive serology, such as antinuclear antibodies (ANA), anti-thyroid antibodies should be evaluated for the presence of target organ involvement and potential need for systemic treatment but should otherwise be eligible.

- •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 would limit compliance with study requirements.
- •Patients with myocardial infarction or myocarditis within 12 months prior to enrollment.
- •History of severe or unstable cerebrovascular disease.
- •Sustained hypotension (<90/50 mmHg) or uncontrolled hypertension (>160/100 mmHg)
- •Stroke within 6 months prior to enrollment.
- •Human immunodeficiency virus (HIV)-positive patients are excluded because HIV causes complicated immune deficiency and study treatment can possess more risks for these patients.
- •Have had prior transplant of any kind.
- •Have ascites.
- •History of allergic reactions attributed to compounds of similar chemical or biologic composition to nivolumab, tadalafil or vancomycin.
- •History of severe hypersensitivity reaction to any monoclonal antibody.
- •Prior invasive malignancy (except non-melanomatous skin cancer) unless disease free for a minimum of 3 years prior to enrollment.
- •Pregnant women are excluded from this study because nivolumabs potential for teratogenic or abortifacient effects is unknown. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with nivolumab, breastfeeding should be discontinued if the mother is treated with nivolumab

结局指标
主要结局
Best Overall Response (BOR)
时间窗: Every 2 months and then every 6 months after discontinuation of treatment, for survival purposes, up to 3 years
Best overall response is defined as the best response recorded from the start of the treatment until disease progression/recurrence (taking as reference for progressive disease the smallest measurements recorded since the treatment started) assessed by the Response Evaluation Criteria in Solid Tumors (RECIST)v1.1. Complete Response (CR) is disappearance of all target lesions. Partial Response (PR) is at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum of diameters. Progressive Disease (PD) is at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). The appearance of one or more new lesions is also considered progressions). Stable Disease (SD) is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum of diameters while on study.
次要结局
- Serious Adverse Events Possibly, Probably, and/or Definitely Related to Treatment(From first study treatment, approximately 90 days)
- Overall Survival (OS) of Nivolumab Combined With Oral Vancomycin and Tadalafil in Participants With Refractory Hepatocellular Carcinoma (HCC) or Liver Dominant Metastatic Cancer From Colorectal Cancer or Pancreatic Ductal Adenocarcinoma (PDAC)(Participants were followed from the on-study date to post discontinuation of treatment until the day of death, an average of 8 months.)
