Genomic profiling and expanded use of targeted anticancer drugs in solid cancers with exhausted evidence-based treatment options: the PRECODE study protocol

Background: Genomic profiling of advanced solid cancer in patients with no further evidence based standard treatment options is a novel approach to identify potential experimental treatment options based on specific genomic alterations. Due to the expected short survival of these patients timely assessment of potential druggable targets is critical to minimize the risk of deterioration during the analysis. The primary objective of this prospective study is to evaluate the turnaround time for genomic profiling and the feasibility of clinical investigational procedures. The secondary objectives are to investigate how often genomic alterations in tumor tissue gives rise to a matched treatment offer and evaluate the clinical outcome. Methods: The PRECODE study is a prospective, non-randomized, single-center cohort study conducted at Departments of Oncology and Pathology, Odense University Hospital, Denmark. Enrollment between March 1, 2019 and December 31, 2024. Eligibility criteria are age > 18 years, written informed consent, advanced solid tumors, exhausted treatment options, ECOG performance status 0-2, adequate organ function and life expectancy > 3 months. A core needle biopsy is analyzed by next generation sequencing using a pan-cancer comprehensive panel. Results are discussed weekly at institutional/local and national multidisciplinary tumor boards. Discussion: Strategies and methods for genomic profiling of advanced solid cancers differ. Rapid analysis and interpretation of sequencing data are key to avoiding delays in initiation potential experimental treatments, as these late-stage patients may quickly deteriorate. A highly optimized setup with fast-track clinical evaluation and genomic profiling has been established. Local and national multidisciplinary teams have been established to optimize individualized treatment decisions Trial registration: ClinicalTrials.gov Identifier: NCT05385081 (retrospectively registered)
