PRESS RELEASE 02/04/2025, 07:00 CEST Biocartis Announces Launch of the Brand-New Idylla™ POLE-POLD1 Mutation Assay Mechelen, Belgium, 02 April 2025 – Biocartis NV (“Biocartis”), an innovative molecular diagnostics company, is pleased to announce the launch of the brand-new Idylla™ POLE-POLD1 Mutation Assay (RUO1), a fully automated, real-time polymerase chain reaction (PCR) Assay designed for the detection of the hypermutated phenotype associated with mutations in POLE and POLD1. POLE and POLD1 are proteins that ensure proper DNA amplification. When these proteins malfunction due to pathogenic mutations, uncontrolled DNA replication occurs, leading to cancer. Mutations in POLE and POLD1 have been identified in endometrial cancers and beyond2,3. POLE-mutated endometrial cancers are considered a distinct subtype in the molecular classification of endometrial cancer samples, next to dMMR/MSI-H, p53abn and NSMP subtypes4. The Idylla™ POLE-POLD1 Mutation Assay, run on the Idylla™ Platform, qualitatively detects 17 point mutations in the POLE gene and one mutation in the POLD1 gene, enabling it to detect 99% of the known POLE and POLD1 pathogenic mutations in a single cartridge. Optimized for use with formalin-fixed, paraffin-embedded (FFPE) tissue specimens, the Idylla™ POLE-POLD1 Mutation Assay offers fast and accurate results, with a hands-on time of under 3 minutes and a turnaround time of approximately 95 minutes, enabling laboratories to go from sample to result in less than 2 hours. Sigurd F. Lax, Professor and Head of Department of General Hospital Graz II5, commented on the new Assay, stating: "The Idylla™ POLE-POLD1 Mutation Assay has the potential to provide an on-demand, fast, and accurate solution, making molecular testing in endometrial cancer samples easier and more accessible than ever.“ At the Association for Molecular Pathology (AMP) 2024 Annual Meeting, Biocartis (Barault et al., 20246) presented the results of a multi-center study to retrospectively detect POLE mutations in endometrial cancer tissue samples (cfr. Press Release 23 October 2024). More than 450 clinical samples were tested using a prototype version of the Idylla™ POLE-POLD1 Mutation Assay, comparing its accuracy against NGS, Sanger sequencing, and qPCR. This prototype study demonstrated 98.2% overall accuracy, highlighting the Assay’s potential. The Assay has since been further enhanced by incorporating additional POLE and POLD1 mutations, achieving a 99% mutation coverage with an impressive 97.2% positive percent agreement and 99.2% negative percent agreement.

AUSTIN, Texas--( BUSINESS WIRE )-- Natera, Inc. (NASDAQ: NTRA), a global leader in cell-free DNA and genetic testing, today announced the enrollment of the first patients in the SAGITTARIUS clinical trial. Sponsored by The AIRC Institute of Molecular Oncology (IFOM-ETS) and funded by the European Union Horizon Europe Programme, SAGITTARIUS is a global, randomized, phase III clinical trial designed to evaluate the use of Signatera to guide personalized adjuvant treatment strategies for patients with colon cancer. The study aims to enroll approximately 700-900 stage III and high-risk stage II colon cancer patients following surgical resection. Signatera-positive patients will be randomized to receive either genotype-guided therapy tailored to their individual tumor mutational profile or six months of standard chemotherapy. The trial’s investigational arm will explore the potential of administering immunotherapy or targeted agents approved for metastatic colon cancer earlier in the disease course to increase the proportion of patients cured with adjuvant therapy. This genomically-driven approach will focus on mismatch repair status, POLE, RAS/RAF mutation status, and HER2 amplification status. For Signatera-negative patients, the trial will compare physician choice treatments with options for de-escalation to observation or single-agent capecitabine for six months. SAGITTARIUS includes collaborations with 9 partners in 5 countries in Europe, and a network of 26 clinical centers in Italy, Spain, and Germany. “ The enrollment of the first patients in SAGITTARIUS represents a significant milestone in a trial that has the potential to transform treatment approaches for colorectal cancer,” said Silvia Marsoni, MD, PhD, head of the precision oncology unit at IFOM ETS and scientific coordinator of the SAGITTARIUS Project. “ The trial aims to move beyond the traditional one-size-fits-all, post-surgical standard of care with chemotherapy by introducing a truly personalized treatment approach tailored to each patient,” said Adham Jurdi, MD, senior medical director of oncology at Natera. “ Signatera-positive patients will receive adjuvant therapies matched to their specific mutational profiles. Additionally, we are optimistic that the study will generate evidence to support the de-escalation of chemotherapy for Signatera-negative patients.” Clara Montagut, MD, PhD, head of the gastrointestinal cancer unit at Hospital del Mar in Barcelona, Spain, and principal investigator of the SAGITTARIUS clinical trial, further emphasized the study’s innovative goals, noting, “ We aim to anticipate the use of therapies tailored to the molecular landscape of the patient’s tumor, including immunotherapy and targeted therapies with proven efficacy in the metastatic setting within the adjuvant treatment context. To our knowledge, SAGITTARIUS is currently the only trial pursuing this approach in the field of liquid biopsy research.” About the SAGITTARIUS Horizon Europe project The SAGITTARIUS clinical trial is part of a wider effort, the SAGITTARIUS project, funded by the European Union Horizon Europe Programme. The SAGITTARIUS project, which also includes health cost and quality of life research to comprehensively assess the full cost-effectiveness of interventional liquid biopsy, aims to pave the way for more effective, tailored treatments that enhance both outcomes and quality of life for colon cancer patients, while potentially lowering the cost impact on private and public health systems and reducing treatment disparities.

In addition, Biocartis will host a free corporate workshop. Six Idylla™ abstracts from renowned institutions will be presented at this year's AMP conference, showcasing the strong collaborations Biocartis has built with leading research and academic partners. 1. Performance Assessment and Clinical Validation of the Idylla™ IDH1-2 Mutation Assay Kit in Rapid Detection of IDH Mutations in Acute Myeloid Leukemia Ashutosh Vashisht, Ashis K Mondal, Lora Walczak, Vishakha Vashisht, Shubha Sharma, Pankaj Ahluwalia, Jana Woodall, Harmanpreet Singh, Ravindra Kolhe - Department of Pathology, Medical College of Georgia, Augusta University, GA, USA. By using 36 samples from 18 unique AML cases, the authors were able to demonstrate perfect concordance (100%) of the Idylla™ IDH1-2 Mutation Assay Kit with NGS. Directly using bone marrow aspirate in the Cartridge significantly reduced turnaround time, making this technique an ideal solution for developing assays for AML diagnosis, prognosis, and treatment evaluation. 2. The Idylla™ Platform Enables Rapid and Accurate EGFR Mutation Assessment in NSCLC with Minimal Sample InputKatherine Drews-Elger, Rodrigo Santoscoy-Valencia, Catherine Garcia-Serje, Silvia Gonzalez-Leiva, Mayra Rodriguez, Orlando Bracho-Rincon, and Roberto Ruiz-Cordero - Department of Pathology and Laboratory Medicine, University of Miami, Miami, FL - Jackson Memorial Hospital, Miami, FL - Clinical OncoMolecular Lab, Department of Pathology and Laboratory Medicine, University of Miami, Miami, FL. This new prospective study demonstrated how the Idylla™ EGFR Mutation Assay offered rapid and accurate detection of EGFR mutations in non-small cell lung cancer (NSCLC), with 95% concordance with NGS. The Assay successfully identified mutations in cases where NGS could not be performed (10% of the cohort) and reduced turnaround time from 12.1 to 1.7 days. With minimal sample requirements and hands-on time, Idylla™ provided a faster option for obtaining EGFR mutation status in NSCLC. 3. Re-verification and Report Ruling Revision of NTRK Fusion Results of Idylla™ GeneFusion Assay after Manufacturer Algorithm UpdatePatricia Caffes, Gang Zheng M.D. Ph.D., Ying-Chun Lo M.D. Ph.D. - Division of Laboratory Genetics and Genomics, Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN - Division of Anatomic Pathology, Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN.
