NCI-COG Pediatric MATCH Study (Molecular Analysis for Therapy Choice) Peter C. Adamson, MD D. Will Parsons, MD, PhD Nita Seibel, MD Pediatric MATCH Target/Agent Prioritization • Is there a clearly defined target or biomarker? • Can the target/biomarker be detected with the proposed testing platform? • What is the frequency of target alterations in pediatric solid tumors and lymphomas? • What is the evidence linking the target to activity of the agent? (clinical vs. pre-clinical) • What are the specific agents in the drug class? • Are trials of the agents already planned in biomarker-defined patient populations? Target/Agent Prioritization • Level 1: FDA approved; evidence of target inhibition, or proof of mechanism; demonstration that patient selection with CDx are more likely to respond • Level 2: Agent met a clinical endpoint (objective response, PFS, or OS); with evidence of target inhibition; plausible evidence of a predictive or selection assay/analyte • Level 3: Agent demonstrated evidence of clinical activity with evidence of target inhibition; some evidence of a predictive or selection assay Target/Agent Prioritization Agent classes initially reviewed ALK inhibitor MEK inhibitor BET bromodomain inhibitor PARP inhibitor BRAF inhibitor PDGFRA/B inhibitor CDK 4/6 inhibitor PI3K/AKT/mTOR inhibitor EGFR inhibitor ROS1 inhibitors ERK inhibitor SMO inhibitor FGFR inhibitor TRK inhibitor IDH inhibitor Target/Agent Prioritization Agent classes not initially reviewed MDM2 inhibitors Target (MDM2 amplification) uncommon ERBB inhibitors Target uncommon Met inhibitor Target (met amplification) uncommon Src/Syk inhibitor Target uncommon c-Kit inhibitor Target uncommon Anti-angiogenic (VEGF and Ang/Tie) Not sufficiently targeted to define biomarker Pan-tyrosine kinase inhibitors Not sufficiently targeted to define biomarker Aurora kinase inhibitors Target/Biomarker not known Base excision repair inhibitor (TRC102) Target/Biomarker not known ATR kinase inhibitor (VX-970) Target/Biomarker not known FAK inhibitor Target/Biomarker not known CK2 inhibitors Target/Biomarker not defined by genomic alteration IGF1R inhibitors Target/Biomarker not defined by genomic alteration Pediatric Match Subprotocols (Subprotocols in development – subject to change) Clinical Sequencing • FFPE tumor samples • Oncomine DNA/RNA mutation panel (Life Technologies/ Thermo Fisher Scientific) • >140 genes • >4000 mutations of interest • defined set of SNVs, indels, CNVs, gene fusions • Analytic pipeline adapted for pediatric study • Sequencing to be initially be performed at two existing MATCH laboratories • Plan to perform germline sequencing in parallel Levels of Evidence: Variants • Level 1: Gene variant approved for selection of an approved drug (BRAF V600E and vermurafenib). The variant will be Level 1 in all tissues open to treatment with the approved drug . • Level 2a: Gene variant is an eligibility criteria for an ongoing clinical trial for that treatment • Level 2b: Gene variant has been identified in an N of 1 responses (TSC1 and everolimus) for that treatment • Level 3: Preclinical inferential data (in vivo and in vitro models) that provide biological evidence sufficient to support the use of a variant for treatment selection Tumor and Germline Mutations • Genomic evaluation of tumors can reveal both tumor and germline cancer mutations • Need plan for interpretation and return of germline results detectable by the study mutation panel NCI-COG Pediatric MATCH Study Study committees • • • • • • Study design and logistics: Target/agent prioritization: Sequencing platform/analysis: Germline result reporting: Biospecimens: Informatics: Stacey Berg, Beth Fox Katie Janeway, Jae Cho Will Parsons, Jim Tricoli Sharon Plon, Steven Joffe Julie Gastier-Foster Hema Chaudhary, David Patton COG leadership and staff • Peter Adamson, Catalina Martinez, Rita Tawdros, Todd Alonzo, Thalia Beeles, Heather Day… NCI/CTEP leadership and staff • Nita Seibel (NCI study PI), Malcolm Smith, adult NCI-MATCH leadership (Conley, Chen, Williams, Patton…) FDA leadership • Martha Donoghue, Greg Reaman NCI-Molecular Analysis for Therapy Choice (NCI-MATCH EAY131) A phase II precision medicine cancer trial Co-developed by the ECOG-ACRIN Cancer Research Group and the National Cancer Institute Mutational Burden Lawrence MS, et al.
