I. To determine the objective response rate (ORR; complete response + partial response) in pediatric patients treated with olaparib with advanced solid tumors (including central nervous system [CNS] tumors), non-Hodgkin lymphomas or histiocytic disorders that harbor activating genetic alterations in the deleterious genetic alterations in the DNA damage repair (DDR) pathway.
I. To estimate the progression free survival in pediatric patients treated with olaparib with advanced solid tumors including non-Hodgkin lymphomas, CNS tumors, and histiocytosis that harbor deleterious genetic alterations in the DDR pathway.
II. To obtain information about the tolerability of olaparib in children and adolescents with relapsed or refractory cancer.
III. To provide preliminary estimates of the pharmacokinetics of olaparib in children and adolescents with relapsed or refractory cancer.
I. To explore approaches to profiling changes in tumor genomics over time through the evaluation of circulating tumor DNA.
Patients receive olaparib orally (PO) twice daily (BID) on days 1-28. Cycles repeat every 28 days for 2 years in the absence of disease progression or unacceptable toxicity.

Experimental: Treatment (olaparib)
Patients receive olaparib PO BID on days 1-28. Cycles repeat every 28 days for 2 years in the absence of disease progression or unacceptable toxicity.
- Objective response rate (complete response/partial response) [ Time Frame: Up to 4 years ]Determined using Response Evaluation Criteria in Solid Tumors version 1.1. A responder is defined as a patient who achieves a best response of partial response or complete response on the study. Response rates will be calculated as the percent of evaluable patients who are responders, and confidence intervals will be constructed using the Wilson score interval method.
- Progression free survival (PFS) [ Time Frame: From the initiation of protocol treatment to the occurrence of disease progression, disease recurrence, or death from any cause, assessed up to 4 years ]PFS along with the confidence intervals will be estimated using the Kaplan-Meier method.
- Incidence of toxicity [ Time Frame: Up to 4 years ]Evaluated according to National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0. Toxicity tables will be constructed to summarize the observed incidence by type of toxicity and grade. A patient will be counted only once for a given toxicity for the worst grade of that toxicity reported for that patient. Toxicity information recorded will include the type, severity, time of onset, time of resolution, and the probable association with the study regimen.
- Pharmacokinetics (PK) of olaparib [ Time Frame: Pre-dose on day 1, and pre-dose, 1, 2, 4, and 6-8 hours after morning dose on day 8 of cycle 1 ]A descriptive analysis of PK parameters will be performed to define systemic exposure, drug clearance, and other pharmacokinetic parameters. The PK parameters will be summarized with simple summary statistics, including means, medians, ranges, and standard deviations (if numbers and distribution permit).
- Change in tumor genomic profile [ Time Frame: Cycle 5 day 1 to 4 years ]Approaches to profiling changes in tumor genomics over time through evaluation of circulating tumor deoxyribonucleic acid will be explored. Descriptive analysis will be performed and will be summarized with simple summary statistics.
