About
This phase II trial studies how well nivolumab works in preventing colon adenomas in participants with Lynch syndrome and a history of surgery to remove part of the colon. Monoclonal antibodies, such as nivolumab, may interfere with the ability of tumor cells to grow and spread.
Full description
PRIMARY OBJECTIVES:
I. To determine if maintenance therapy with nivolumab can decrease the incidence of colon adenomas in a population of patients with genetic predisposition to colorectal cancer and a history of hemicolectomy due to colon cancer or advanced colon adenoma.
SECONDARY OBJECTIVES:
I. To assess the safety of nivolumab maintenance therapy in this population. II. To obtain preliminary data on the short-term incidence of advanced colon adenomas (measuring greater than 10 mm or with high-grade dysplasia) and colon and non-colonic cancers in Lynch patients treated with maintenance nivolumab.
EXPLORATORY OBJECTIVES:
I. To determine biomarkers of immunologic activity associated with biologic activity of nivolumab in this population.
OUTLINE:
Participants receive nivolumab intravenously (IV) over 60 minutes on day 1. Treatment repeats every 3 months for a total of 8 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, participants are followed up at 3 months, every 6 months for 1 year, then every 12 weeks thereafter.

Inclusion criteria
Exclusion criteria
Is currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of the first dose of treatment.
Has a diagnosis of immunodeficiency or is receiving immunosuppressive therapy within 7 days prior to the first dose of trial treatment. Individuals who are receiving systemic steroid therapy at a stable dose less than or equal to 10 mg of prednisone per day or its equivalent will be permitted to participate.
Has a known history of active TB (Bacillus tuberculosis).
Hypersensitivity to nivolumab or any of its excipients.
Has had a prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to study day 1 or who has not recovered (i.e., =< grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier.
Has had hemicolectomy, prior chemotherapy, targeted small molecule therapy, or radiation therapy within one year prior to study day 1 or who has not recovered (i.e., =< grade 1 or at baseline) from adverse events due to a previously administered agent.
Has a known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer.
Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids exceeding 10 mg prednisone per day or its equivalent, or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
Has known history of, or any evidence of, active, non-infectious pneumonitis.
Has an active infection requiring systemic therapy.
Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject?s participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.
Have a known history of a bleeding disorder or gastrointestinal ulceration that would preclude the use of a daily 81 mg aspirin.
Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
Is pregnant or breastfeeding or is expecting to conceive or father children within the projected duration of the trial, starting with the pre-screening or screening visit through 120 days after the last dose of trial treatment.
Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent.
Has a known history of human immunodeficiency virus (HIV) (HIV 1/2 antibodies).
Has known active hepatitis B (e.g., hepatitis B surface antigen [HBsAg] reactive) or hepatitis C (e.g., hepatitis C virus [HCV] ribonucleic acid [RNA] [qualitative] is detected).
Has received a live vaccine within 30 days of planned start of study therapy.
Subjects with germline MSH6, PMS2, or EPCAM mutations will be excluded from participation.
Prisoners or individuals who are compulsorily detained will be excluded from participation.
