Study of Nivolumab and Ipilimumab in Children and Young Adults With INI1-Negative Cancers

Study Overview
=================
Brief Summary
-----------------
This clinical trial is studying two immunotherapy drugs (nivolumab and ipilimumab) given together as a possible treatment for INI1-negative tumors.

Detailed Description
-----------------
This research study is a Phase II clinical trial, which tests the safety and effectiveness of an investigational drug or drug combination to learn whether the drug or drug combination works in treating a specific disease. Investigational means that the drug combination is being studied. The names of the study drugs involved in this study are: Nivolumab (OPDIVO) Ipilimumab (YERYOY) This trial is studying whether nivolumab and ipilimumab work to treat INI1-negative cancers. The U.S. Food and Drug Administration (FDA) has not approved combination nivolumab and ipilimumab for the specific diseases in this study but it has been approved for other diseases. Nivolumab and ipilimumab have been tested in children to find out a safe dose of this combination.

OR Creatinine clearance ≥ 70 mL/min/1.73 m2 for participants with creatinine levels above institutional normal Adequate Pulmonary Function Defined as: no evidence of dyspnea at rest, no exercise intolerance due to pulmonary insufficient and a pulse oximetry > 92% while breathing room air Adequate pancreatic function defined as serum lipase ≤ ULN at baseline Negative B-HCG pregnancy test in females of childbearing potential (must be drawn within 24 hours prior to initial administration of nivolumab) Women of childbearing potential (WOCBP) receiving nivolumab agree to adhere to contraception for a period of 5 months after the last dose of nivolumab. Men receiving nivolumab and who are sexually active with WOCBP will agree to adhere to contraception for a period of 7 months after the last dose of nivolumab. Ability to understand and/or the willingness of the patient (or parent or legally authorized representative, if minor) to provide informed consent using an institutionally approved informed consent procedure. Exclusion Criteria: Participants who are receiving any other investigational agents. Participants must not be receiving concomitant systemic steroid medications The use of physiologic doses of corticosteroids (up to 5 mg/m2/day prednisone equivalent) may be approved after consultation with the PI (treatment with topical, inhaled or ophthalmic corticosteroid is acceptable) Participants with a known history of HIV, hepatitis B, and/or hepatitis C Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection or any other concurrent disease which in the judgment of the Investigator would make the subject inappropriate for enrollment on this study Has a history of (non-infectious) pneumonitis that required steroids or has current pneumonitis Has active autoimmune disease that has required systemic treatment in the past 12 months, or a documented history of clinically severe autoimmune disease, or a syndrome that requires systemic steroids or immunosuppressive agents. Subjects with vitiligo or resolved childhood asthma/atopy are exceptions. Intermittent use of bronchodilators or local steroid injections are not excluded. 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. Autoimmune diagnoses not listed must be approved by the Principal Investigator. Patients who have received prior solid organ transplantation are not eligible. Pregnancy or Breast-Feeding. Pregnant or breast-feeding women will not be entered on this study due to risks of fetal and teratogenic adverse events as there is yet no available information regarding human fetal or teratogenic toxicities. Pregnancy tests must be obtained in girls who are post-menarchal. Has received prior therapy with an anti-PD-1, anti-PD-L1, anti-PD-L2 or anti-CTLA4 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (e.g. OX-40, CD137) Participants who have received live / attenuated vaccine within 30 days of first dose of study treatment.
