ADVL1312: A Phase 1/2 Study of MK-1775 in Combination With Irinotecan in Children, Adolescents, and Young Adults With Relapsed or Refractory Solid Tumors

What is the purpose of this study?

This phase I/II trial studies the side effects and best dose of WEE1 inhibitor MK-1775 and irinotecan hydrochloride in treating younger patients with solid tumors that have come back or that have not responded to standard therapy. WEE1 inhibitor MK-1775 and irinotecan hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth

·         At least 14 days after the last dose of a long-acting growth factor (e.g. Neulasta) or 7 days for short-acting growth factor; for agents that have known adverse events occurring beyond 7 days after administration, this period must be extended beyond the time during which adverse events are known to occur; the duration of this interval must be discussed with the study chair

·         At least 7 days after the last dose of a biologic agent; for agents that have known adverse events occurring beyond 7 days after administration, this period must be extended beyond the time during which adverse events are known to occur; the duration of this interval must be discussed with the study chair

·         At least 42 days after the completion of any type of immunotherapy, e.g. tumor vaccines

·         At least 3 half-lives of the antibody after the last dose of a monoclonal antibody

·         At least 14 days after local palliative radiation therapy (XRT) (small port); at least 150 days must have elapsed if prior traumatic brain injury (TBI), craniospinal XRT or if >= 50% radiation of pelvis; at least 42 days must have elapsed if other substantial bone marrow radiation, including therapeutic doses of Iobenguane (MIBG)

·         Stem cell Infusion without TBI: no evidence of active graft vs host disease and at least 84 days must have elapsed after transplant or stem cell infusion

·         Patients previously treated with irinotecan are eligible for this study

·         For patients with solid tumors without known bone marrow involvement: peripheral absolute neutrophil count (ANC) >= 1000/mm^3

·         For patients with solid tumors without known bone marrow involvement: hemoglobin >= 8.0 g/dL (may receive red blood cell [RBC] transfusions)

·         Patients with known bone marrow metastatic disease will be eligible for study provided they meet the blood counts (may receive transfusions provided they are not known to be refractory to red cell or platelet transfusions); these patients will not be evaluable for hematologic toxicity; at least 2 of every cohort of 3 patients must be evaluable for hematologic toxicity for Part A, the dose escalation part of the study; if dose limiting hematologic toxicity is observed, all subsequent patients enrolled must be evaluable for hematologic toxicity

·         Creatinine clearance or radioisotope glomerular filtration rate (GFR) >= 70ml/min/1.73 m^2 or a serum creatinine based on age/gender as follows:

o   Age 1 to < 2 years: 0.6 mg/dL

o   Age 2 to < 6 years: 0.8 mg/dL

·         Bilirubin (sum of conjugated + unconjugated) =< 1.5 x upper limit of normal (ULN) for age

·         SGPT is 45 U/L

·         Serum albumin >= 2 g/dL

·         Patients with seizure disorder may be enrolled if on non-enzyme inducing anticonvulsants and well controlled

·         Nervous system disorders (Common Terminology Criteria for Adverse Events version 4 [CTCAE v4]) resulting from prior therapy must be =<grade 2

·         All patients and/or their parents or legally authorized representatives must sign a written informed consent; assent, when appropriate, will be obtained according to institutional guidelines
