U.S. researchers reported seeking patent protection for methods to neutralize circulating tumor cells (CTCs) during hemodialysis to prevent cancer metastasis and reduce cancer-related deaths.

In a positive sign for its future success, Harbinger Health Inc. closed a $140 million series B fundraising round, bringing total funds raised since its founding in 2020 to $190 million. The new funds will be used to support completion of the company’s CORE-HH 10,000 participant study of its blood-based multicancer early detection (MCED) test. The company expects to complete enrollment in CORE-HH, a three-part case control, adaptive study with development, validation and longitudinal cohorts in 2024.

Mission Bio Inc. released its Tapestri single-cell minimal residual disease (MRD) assay for acute myeloid leukemia (AML) on September 26, with the goal of enabling greater personalization of care for patients with blood cancers. The test can provide insights into the progression of AML and help identify targets for treatment in addition to identifying patients truly experiencing relapse as distinct from having pre-leukemic or precursor clones.

Proteomics International Pty Ltd has developed a new blood-based diagnostic test called the Promarkereso that identifies patients with esophageal adenocarcinoma as well as patients with a pre-malignant condition called Barrett’s esophagus that can arise from chronic acid reflux.

A fluorescent imaging agent developed by Vergent Bioscience Inc. enables visualization of elusive and previously undetected tumors, a phase II study presented last week at the 2023 World Conference on Lung Cancer (WCL23) demonstrated. The ability of the tumor-targeting agent, Vgt-309, to illuminate tumors could help surgeons more precisely locate tumors, better ensure clean margins and guide care decisions. In 10% of cases, the agent revealed unknown tumors in lymph nodes, which could affect which nodes are biopsied as well as when or whether a systemic therapy is recommended.

The U.K. government continues to pump money into research projects focusing on the use of artificial intelligence (AI) in health care as it looks to technology to help diagnose and treat patients. It provided £2 million (US$2.5 million) in funding to test innovative ways to tackle cancers with poor survival rates.

Limaca Medical Ltd. received U.S. FDA 510(k) clearance for its Precision for gastrointestinal (GI) endoscopic ultrasound (EUS) biopsy device which the company said allows for faster, more efficient and safer collection of tumor tissue samples. The approval follows the receipt of breakthrough device designation, and the deployment of the device into the U.S. market should lead to more efficient and effective diagnosis of GI cancers.

Nevia Bio Ltd. (formerly Gina Life Ltd.) completed a $3.1 million seed round that will allow the company, which has developed a platform that can decode biomarkers data from vaginal secretions for the early detection of ovarian cancer, to conduct clinical trials. With ovarian cancer the leading cause of death in women diagnosed with gynecological cancers, Nevia is hoping that its platform will save many lives.

Aion Biosystems Inc. may be operating at a fever pitch right now, with FDA 510(k) clearance in hand for the company’s Itempshield device, which provides continuous measurement of body temperature. The company is targeting use of the quarter-sized device for patients with cancer and individuals in long-term care.
