The potential of urine as liquid biopsy sample
Liquid biopsies offer a dynamic and minimal invasive window into cancer biology. While tissue biopsies provide a localized snapshot of a tumour, liquid biopsies can offer a broader and more dynamic view of the disease over time. This creates opportunities for early cancer detection, assessment of cancer treatment response, and surveillance for cancer recurrence.
Urine is particularly attractive as liquid biopsy medium because it can be collected noninvasively, repeatedly, and even at home without the involvement of a healthcare professional. Its availability also supports serial sampling and the potential for multiomics (combined analysis of multiple biological data types such as DNA, RNA, proteins and metabolites).
Importantly, its potential may extend beyond cancer of the urogenital tract: small fragments of circulating cell-free DNA, including tumour-derived DNA, can cross the renal filtration barrier and enter the urine. This transrenal DNA could provide molecular information about cancers elsewhere in the body.

Our comprehensive approach
We have established two complementary R&D programs designed to unlock the diagnostic potential of urine.
1. Qatra Program: capturing biomarkers from urine
Detecting cancer and monitoring treatment response depend on the reliable recovery of biomarkers such as DNA, RNA and proteins. Through the Qatra Program, we develop technologies that efficiently capture and extract these biomarkers, even when present at very low concentrations, from a full void of urine, without limiting collection to first-morning or midstream samples. The products resulting from this program, are designed for full automation processing and delivers high yields of high-quality biomarkers suitable for downstream molecular analysis.
2. Qumbra Program: clinically actionable assays
The Qumbra Program translates the biological signals, extracted from urine, into clinically meaningful insights in the field of oncology. Starting with a clearly defined unmet medical need, we develop assays that analyse selected urinary biomarkers and use interpretive software to assess the results. The findings are presented in a clear clinical report, providing healthcare professionals and patients with additional information to support decisions along the care pathway.
