Clinical trial: 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)

Summary: 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 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.
