Urteste S.A. has developed a urine-based diagnostic test for the early detection of brain tumors. The prototype, which can detect the activity of brain-specific enzymes in urine, is a breakthrough test and the first solution of this type in the world, Grzegorz Stefański, CEO and co-founder of Urteste S.A., told BioWorld.

The American Society of Clinical Oncology (ASCO) begins its 2024 annual meeting at the cavernous and labyrinthine McCormick Place convention center in Chicago Friday, May 31. It’s one of the world’s largest cancer research conferences and can be daunting to follow.  More than 400 organizations will participate this year, with about 200 sessions ready to convene. The vast majority of the 5,000 abstracts that cover all aspects of cancer treatment have already been released, and they will be scrutinized by the more than 40,000 attendees from around the world.

Oncohost Ltd. provided new details on a novel application for its proteomic pattern analysis technology at Biomed Israel last week. While its initial development focused on using a single blood sample to guide selection of first-line immunotherapy for cancer based on likelihood of response, the Prophet platform now also predicts severe adverse immune-related events, Oncohost CEO Ofer Sharon told BioWorld.

The U.S. FDA’s May 23 advisory hearing for the Shield test for colorectal cancer by Guardant Health Inc., included the expected debate over whether patients would abandon colonoscopy thanks to the advent of a new blood-based test. While much of that debate was fed by what some saw as the test’s poor performance regarding adenoma, the advisory committee voted 6-3 that the benefits outweigh the risks in a decision the FDA is likely to affirm.

At its investor presentation on May 22, Roche Diagnostics, a unit of Basel Switzerland-based Roche Holding AG reported on the company's pipeline plans, which include a slew of new tests, instrument upgrades, and the forthcoming launch of its fully automated mass spectrometry instrument.

Liquid biopsy typically means blood testing, but several companies presenting at Biomed Israel May 21-23 have developed diagnostics that look to other, even less invasive options, and ever broader applications. Nevia Bio Ltd. is using vaginal secretions to detect ovarian cancer, while Early OM Ltd. and Nucleix Ltd. analyze urine for cancer biomarkers.

The Surveillance Heartcare Outcomes Registry trial demonstrated that Caredx Inc.’s Heartcare test identifies acute cellular rejection in heart transplant patients better than donor-derived cell-free DNA (dd-cfDNA) alone, while reducing biopsies and improving clinical outcomes. Heartcare combines two non-invasive tests, dd-cfDNA and Allomap Heart gene-expression profiling.

As the average cost of new drug R&D continues to skyrocket, the perception around using artificial intelligence (AI) as a tool to boost drug discovery is changing. “Developing new AI-based drugs is a difficult task, not only for Korea but also for countries with leading AI technology,” Hyeyun Jung, principal researcher of Korea Health Industry Development Institute’s Center for Health Industry Policy, told the audience at the Bio Korea meeting on May 9. “But there is a change in perception; [namely that] applying AI to new drug development is not an option but a necessity.”

Profound Medical Corp. received U.S. FDA 510(k) clearance for its second transurethral ultrasound ablation (TULSA) module using artificial intelligence. When used with Profound’s TULSA-Pro system, the Contouring assistant helps physicians more quickly and accurately segment prostate imaging and design treatments.
