I. To determine the objective response rate (ORR; complete response + partial response) in pediatric patients treated with PI3K/mTOR inhibitor LY3023414 (LY3023414) with advanced solid tumors, non-Hodgkin lymphomas or central nervous system (CNS) tumors that harbor TSC loss of function mutations, that harbor other PI3K/MTOR activating mutations, and if efficacy is observed in a MATCHed cohort, in patients that lack mutations in the PI3K/MTOR pathway.
I. To estimate the progression free survival in pediatric patients treated with LY3023414 with advanced solid tumors, non-Hodgkin lymphomas or CNS tumors that harbor TSC loss of function mutations, that harbor other PI3K/MTOR activating mutations, or if efficacy is observed in a MATCHed cohort, that lack mutations in the PI3K/MTOR pathway.
II. To obtain information about the tolerability of LY3023414 in children with relapsed or refractory cancer.
III. To characterize the pharmacokinetics of LY3023414 in children with recurrent or refractory cancer.
IV. If efficacy is observed in a MATCHed cohort, to obtain preliminary information on the response rate to LY3023414 in patients that lack mutations in the PI3K/MTOR pathway.
I. To increase knowledge of the genomic landscape of relapsed pediatric solid tumors and lymphomas and identify potential predictive biomarkers (other than the genomic alteration for which study treatment was assigned) using additional genomic, transcriptomic, and proteomic testing platforms.
II. To explore approaches to profiling changes in tumor genomics over time through evaluation of circulating tumor deoxyribonucleic acid (DNA).
III. To evaluate the frequency and mechanism of biallelic loss of function, and evaluate the expression of TSC1, TSC2, and PTEN in subjects who enroll with a loss of function mutation in one of these genes.
OUTLINE: This is a dose-escalation study.
Patients receive PI3K/mTOR inhibitor LY3023414 orally (PO) twice daily (BID) on days 1-28. Courses repeat every 28 days for up to 2 years in the absence of disease progression or unexpected toxicity.
After completion of study treatment, patients are followed up periodically.

- Response rate [ Time Frame: 3 years ]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.
- Incidence of adverse events graded by National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0 [ Time Frame: Up to 3 years ]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.
- Progression free survival (PFS) [ Time Frame: From the initiation of protocol treatment to the occurrence of any of the following events: disease progression or disease recurrence or death from any cause, assessed up to 3 years ]PFS along with the confidence intervals will be estimated using the Kaplan-Meier method.
- Pharmacokinetic (PK) parameters [ Time Frame: At baseline, 30 minutes, 1, 2, 4, 4, 6-8 hours, and 24 hours after the morning dose on day 1 course 1, pre-dose and at 1-2 hours after the morning dose on day 15 course 1 ]A descriptive analysis of pharmacokinetic (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).
- Potential predictive biomarker identification using additional genomic, transcriptomic, and proteomic testing platforms [ Time Frame: Up to 3 years ]A descriptive analysis will be performed and will be summarized with simple summary statistics. All of these analyses will be descriptive in nature.
- Biallelic loss of function frequency and mechanism [ Time Frame: Up to 3 years ]A descriptive analysis will be performed and will be summarized with simple summary statistics. All of these analyses will be descriptive in nature.
- Change in tumor genomic profile [ Time Frame: Baseline up to 3 years ]A descriptive analysis will be performed and will be summarized with simple summary statistics. All of these analyses will be descriptive in nature.
- TSC1, TSC2, and PTEN expression levels [ Time Frame: Up to 3 years ]
