Oncular expands access to advanced molecular testing to support patient management for a rare eye cancer
ROCKVILLE, Md. and ZURICH, May 12, 2026 /PRNewswire/ -- TrilliumBiO, a leader in biomarker discovery and precision diagnostics, and Oncobit, a Swiss precision oncology company, today announced the launch of Oncular, bringing Oncobit's uveal melanoma monitoring solution to the U.S. through TrilliumBiO's multi-accredited laboratory. The assay expands access to advanced molecular testing for patients with uveal melanoma, a rare and historically underserved cancer.
Oncular brings Oncobit's proprietary platform for personalized cancer monitoring to physicians nationwide, enabling real-time, quantitative assessment of circulating tumor DNA (ctDNA) from a simple blood draw. Designed to complement conventional imaging approaches, the assay provides precise insights into disease dynamics, supporting informed patient management across the care continuum.
Unlike traditional monitoring methods that rely primarily on imaging or nonspecific blood markers, Oncular combines personalized digital PCR with standardized, cloud-based data analysis to deliver sensitive and reproducible molecular results. This approach addresses key limitations of existing monitoring strategies, including limited sensitivity, delayed detection of disease progression, high cost, and invasiveness. The approach is designed to be both time- and cost-efficient while remaining scalable for routine clinical practice.
Oncular delivers molecular monitoring insights, including:
- Molecular residual disease (MRD) status
- Longitudinal ctDNA trends
- Early molecular signals of treatment response or disease progression, which may precede
radiographic findings
Published research has demonstrated that ctDNA dynamics measured using Oncobit's proprietary platform can predict treatment response and disease progression in metastatic uveal melanoma, underscoring the clinical relevance of this testing approach.1,2,3
"Launching Oncular in the U.S. reflects our commitment to translating innovative science into high-quality diagnostic solutions for patients with rare diseases," said Laura Vivian, CEO of TrilliumBiO. "By making this assay available through our laboratory, we are helping clinicians access reliable insights to better understand disease behavior and support patient care."
The launch combines TrilliumBiO's expertise in assay implementation and clinical laboratory operations with Oncobit's leadership in precision oncology and ctDNA-based testing. Oncular is a laboratory-developed test (LDT) performed within TrilliumBiO's CLIA-certified and CAP-accredited laboratory infrastructure, ensuring consistency, quality, and nationwide availability.
"We are thrilled to see our uveal melanoma assay reach clinical practice in the U.S. with TrilliumBiO," said Dr. Claudia Scheckel, CEO of Oncobit. "The launch of Oncular represents an important step toward expanding access to advanced molecular testing for this rare cancer and supports continued progress in biomarker development and advancing precision oncology."
Together, TrilliumBiO and Oncobit aim to improve disease understanding and patient management in uveal melanoma by providing clinicians with sensitive, informative molecular testing to support evidence-based care decisions.
