TCF-001 TRACK (Target Rare Cancer Knowledge): A national patient-centric precision oncology trial for rare cancers.

Abstract

TPS3143 Background: Many rare cancers are understudied, and affected patients often have few if any standard treatment options and limited access to clinical trials. Comprehensive genomic profiling (CGP) is a robust tool to efficiently identify the genomic alterations of cancer and can be applied to study rare tumors. The promise of this technology is to simultaneously enhance our understanding of diverse rare tumors and find matched therapies to benefit the individual patient in real-time. The COVID19 pandemic has challenged the “trial-centric” clinical trial infrastructure. Novel “patient-centric” trials are needed, especially for rare cancers. TRACK is a decentralized, patient advocacy-initiated trial that aims to establish whether patients with rare tumors and cancer of unknown primary can benefit from matched molecular therapy as dictated by their CGP results. Methods: This is a national open label, non-randomized, multi-center (includes community and academic centers) pragmatic study in rare tumors (<6 cases per 100,000 persons per year) and cancer of unknown primary. All participants will have tumor tissue and blood analyzed by CGP (FoundationOneCDx and FoundationOneLiquidCDx). A Virtual Molecular Tumor Board (VMTB) will convene to identify targeted treatment recommendations for participants with genomic alterations. Overall, 400 participants will be enrolled to achieve the goal of 100 patients matched to genomically informed treatment, utilizing remote consenting to ensure study access regardless of geographic location. The primary feasibility endpoint is the percent of participants who receive a molecularly matched treatment after recommendation from the VMTB. The primary efficacy endpoint is the progression-free survival (PFS) among participants who received the molecularly matched treatment. Secondary endpoints include the percent of participants with genomic alterations, overall response rate, response duration, overall survival, clinical benefit rate (SD > 6 months; PR; CR), and high-grade toxicities (as available) of matched targeted therapy. Exploratory endpoints include matching rates; understanding genomic correlates of response; concordance rates between CGP from tissue and blood, time-to-treatment failure, and the impact of the cancer treatment from the patient perspective (via ESAS-FS, a validated patient-reported outcomes (PRO) instrument). All eligible and enrolled patients, regardless of whether receiving matched treatment or not, will be followed for a minimum of one year in a uniform way such that the treatment efficacy and outcomes can be assessed in standard formats. The study is open with six patients enrolled at time of submission. Clinical trial information: NCT04504604.
