Targeted Therapy Directed by Genetic Testing in Treating Pediatric Patients With Relapsed or Refractory Advanced Solid Tumors Non-Hodgkin Lymphomas or Histiocytic Disorders (The Pediatric MATCH Screening Trial)


Brief description of study

This Pediatric MATCH screening and multi-sub-study phase II trial studies how well treatment that is directed by genetic testing works in pediatric patients with solid tumors, non-Hodgkin lymphomas, or histiocytic disorders that have progressed following at least one line of standard systemic therapy and/or for which no standard treatment exists that has been shown to prolong survival. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic changes or abnormalities (mutations) may benefit more from treatment which targets their tumor's particular genetic mutation, and may help doctors plan better treatment for patients with solid tumors or non-Hodgkin lymphomas.

Detailed Study Description

PRIMARY OBJECTIVES:

I. To utilize clinical and biological data to screen for eligibility to phase 2 pathway-targeting specific subprotocols of pathway-targeting agents in pediatric patients with advanced solid tumors, non-Hodgkin lymphomas, and histiocytic disorders.

II. To determine the proportion of pediatric patients whose advanced tumors have pathway alterations that can be targeted by select anti-cancer drugs.

III. To determine the objective response rates (ORR; complete response + partial response) in pediatric patients with advanced solid tumors, non-Hodgkin lymphomas, and histiocytic disorders harboring a priori specified genomic alterations treated with pathway-targeting agents.

SECONDARY OBJECTIVES:

I. To estimate the progression free survival in pediatric patients receiving targeted therapies for advanced solid tumors, non-Hodgkin lymphomas, and histiocytic disorders.

II. To obtain preliminary or additional information about the tolerability of targeted therapies in children with advanced cancers.

III. To provide preliminary estimates of the pharmacokinetics of targeted therapies in children with advanced cancers.

IV. To obtain preliminary information on the response rate to targeted therapy in patients whose tumors lack actionable alterations as defined for the molecular analysis for therapy choice (MATCH) study, for selected agents for which efficacy is observed in the primary matched cohort.

TERTIARY OBJECTIVES:

I. To increase knowledge of the genomic landscape of advanced pediatric solid tumors, non-Hodgkin lymphomas, and histiocytic disorders.

II. To describe the genomic changes that occur in advanced pediatric cancers between the time of initial diagnosis and relapse, in cases for which paired tumor specimens are available.

III. To explore approaches to diagnosing and profiling genomics of advanced pediatric cancers through evaluation of circulating tumor deoxyribonucleic acid (DNA).

IV. To determine the frequency and spectrum of germline cancer susceptibility mutations in children with relapsed solid tumors and non-Hodgkin lymphomas and assess the feasibility of return of those results in the National Clinical Trial Network (NCTN) group setting.

OUTLINE

STEP 1 (SCREENING): Patients undergo biopsy along with tumor mutational screening of the biopsy material for specific, pre-defined mutations, amplifications, or translocations of interest via tumor sequencing and immunohistochemistry. Patients also undergo collection of blood samples for research purposes.

STEP 2 (TREATMENT): Patients with a mutation targeted by one or more of the investigational drugs used in this study or those without mutations are assigned to 1 of 10 treatment subprotocols.

APEC1621A: Patients with a NTRK1, NTRK2, or NTRK3 gene fusion receive Trk inhibitor LOXO-101 orally (PO) or via nasogastric- or gastric-tube twice daily (BID) on days 1-28. Courses repeat every 28 days for 2 years in the absence of disease progression or unacceptable toxicity.

APEC1621B: Patients with a FGFR1, FGFR2, FGFR3, or FGFR4 gene mutation receive pan-FGFR tyrosine kinase inhibitor JNJ-42756493 PO once daily on days 1-28. Courses repeat every 28 days for up to 2 years in the absence of disease progression or unacceptable toxicity.

APEC1621C: Patients with an EZH2, SMARCB1, or SMARCA4 gene mutation receive tazemetostat PO BID on days 1-28. Courses repeat every 28 days for 2 years in the absence of disease progression or unacceptable toxicity.

APEC1621D: Patients with a TSC1, TSC2, or PI3K/mTOR gene mutations receive PI3K/mTOR inhibitor LY3023414 PO BID on days 1-28. Courses repeat every 28 days for 2 years in the absence of disease progression or unacceptable toxicity.

APEC1621E: Patients with an activating MAPK pathway gene mutation receive selumetinib sulfate PO BID on days 1-28. Courses repeat every 28 days for 2 years in the absence of disease progression or unacceptable toxicity.

APEC1621F: Patients with an ALK or ROS1 gene alteration receive ensartinib (ALK Inhibitor X-396) PO BID on days 1-28. Courses repeat every 28 days for 2 years in the absence of disease progression or unacceptable toxicity.

APEC1621G: Patients with a BRAF V600 gene mutation receive vemurafenib PO BID on days 1-28. Courses repeat every 28 days for 2 years in the absence of disease progression or unacceptable toxicity.

APEC1621H: Patients with deleterious ATM, BRCA1, BRCA2, RAD51C, or RAD51D gene mutations receive olaparib PO BID on days 1-28. Courses repeat every 28 days for 2 years in the absence of disease progression or unacceptable toxicity.

APEC1621I: Patients with Rb positive advanced solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with activating alterations in cell cycle genes receive palbociclib PO QD on days 1-21. Courses repeat every 28 days for up to 2 years in the absence of disease progression or unacceptable toxicity.

APEC1621J: Patients with MAPK Pathway Mutations receive ulixertinib PO BID. Courses repeat every 28 days for up to 2 years in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up periodically.
