简要总结
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.
详细描述
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.

- •Albumin >= 2.5 mg/dL within 10 days of treatment initiation.
- •International normalized ratio (INR) or prothrombin time (PT) =< 1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or partial thromboplastin time (PTT) is within therapeutic range of intended use of anticoagulants within 10 days of treatment initiation.
- •Activated partial thromboplastin time (aPTT) =< 1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants within 10 days of treatment initiation.
- •Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin [HCG]) within 24 hours prior to the start of study drug.
- •Women must not be breastfeeding.
- •WOCBP must agree to follow instructions for method(s) of contraception for the duration of treatment with nivolumab plus 5 half-lives of nivolumab (19 weeks) plus 30 days (duration of ovulatory cycle) for a total of 23 weeks post-treatment completion.
- •Men who are sexually active with WOCBP must agree to follow instructions for method(s) of contraception for the duration of treatment with nivolumab plus 5 half-lives of the study drug (19 weeks) plus 90 days (duration of sperm turnover) for a total of 31 weeks post-treatment completion.
- •Hemicolectomy and adjuvant chemotherapy (if given) must be completed at least one year prior to study entry.
- •All subjects must take at least 81 mg of aspirin per day. Daily doses up to 650 mg of aspirin per day will be accepted.
排除标准
- •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.
- •Note: Subjects with =< grade 2 neuropathy and/or alopecia are an exception to this criterion and may qualify for the study.
- •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).

- •Note: Seasonal influenza vaccines for injection are generally inactivated flu vaccines and are allowed; however intranasal influenza vaccines (e.g., Flu-Mist) are live attenuated vaccines, and are not allowed.
- •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.
