Target enrollment:
0
Participant gender:
All
Summary
This phase I/II trial studies the side effects and best dose of adavosertib and irinotecan hydrochloride in treating younger patients with solid tumors that have come back (relapsed) or that have not responded to standard therapy (refractory). Adavosertib and irinotecan hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

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

vaccines

related to prior antibody therapy must be recovered to grade =< 1

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)

least 84 days must have elapsed after transplant or stem cell infusion

absolute neutrophil count (ANC) >= 1000/mm^3

>= 100,000/mm^3 (transfusion independent, defined as not receiving platelet
transfusions for at least 7 days prior to enrollment)

- 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
