In the coming months, Urteste plans to start a multi-centreclinicaltrialintheUSandEuropeforitsflagshipprojectPANURI,atestforpancreaticcancer.

Urteste’s breakthrough technology allows for early detection of cancer by measuring the activity of enzymes present in urine using proprietary synthetic peptides. One urine sample can be used to screen for many types of cancers. Urteste technology is non-invasive, low-cost to produce, has high sensitivity and specificity, and results are available in up to 2 hours. The diagnostic process is automated to minimize the likelihood of human error.

PANURI - the pancreatic cancer test is Urteste's flagship and most advanced project. Pancreatic cancer is one of the worst prognosis cancers. A proof-of-concept study of 322 participants confirmed the high sensitivity (95.6%) and specificity (95.5%) of the PANURI test. Urteste is currently undergoing an FDA Q-Submission programme.

“In recent years, we have worked intensively to develop our unique technology platform for the earlierdetectionofoveradozenofthemostcommoncancers.Asaresult,wearenowclosetostartingclinicaltrials for our flagship PANURI project.

In the MULTI-CANCER project, Urteste is developing a diverse portfolio of tests. The company already has prototypes of 12 diagnostic tests for the most common cancers. In the coming months, Urteste plans to add the final prototypes to its pipeline and complete the prototype development phase of the tests. The company will then focus on preparing for clinical trials.

Urteste holds polish patents and international patent applications for its technology. Urteste's patent strategy is to seek patent protection in countries that collectively generate around 90% of global GDP.

The Urteste Management Board will attend the BIO International Convention in San Diego, 3-6 June.
