The U.S. FDA’s final rule for regulation of lab-developed tests was hardly a shock to the world of regulation, but the final rule might provide a shock for sorts for smaller entities in the diagnostics space. Analysts with Leerink Partners said most companies they routinely track are unlikely to be immediately affected by the final rule, but noted that FDA regulation might make it tougher for smaller, new entries to the space to get to market.

The U.S. FDA has posted the long-awaited final rule for lab-developed tests, which amends the draft rule in a few key respects, but Reps. Diana DeGette and Larry Buchson, once again voiced their opposition to the rule. DeGette and Bucshon acknowledged that congressional inaction has left the FDA with few choices, but called again for passage of the Verifying Accurate, Leading-edge IVCT Development (VALID) Act, which they said is critical because “burdensome regulation of these medical products creates uncertainty in the future of innovation and patient care.”

In what represents just the third PCT filing to have been published in the name of Zurich, Switzerland-based Siva Health AG, protection is sought for a computer-implemented method of classifying an individual suffering from chronic cough.

Sunbird Bio Inc. is advancing its blood-based diagnostics platform for neurological diseases like Alzheimer’s and Parkison’s disease (AD/PD), amidst new breakthroughs in the AD drug therapies and diagnostics space.

Owlstone Medical Ltd. received $6.5 million in funding from the Bill & Melinda Gates Foundation which will go towards expanding its Breath Biopsy platform as well as developing breath-based diagnostic tests to identify breath biomarkers for tuberculosis and HIV.

Molecular You Corp. said it has achieved a significant milestone in the early detection of pancreatic cancer. A case report, published in the journal OMICS, described the effectiveness of the company’s proteomic and metabolomic analysis – known as longitudinal multiomics monitoring (LMOM) – in identifying pancreatic cancer in a symptom-free 60-year-old female patient. A biopsy on lesions discovered because of the company’s diagnostic tests confirmed stage 1 pancreatic cancer.

Quest Diagnostics Inc. expanded its Alzheimer’s disease (AD) portfolio with a blood-based biomarker test for phosphorylated tau 217 (pTau217). The test joins the company’s plasma tests for p-tau181, beta-amyloid 42/40 ratio and ApoE genetic risk as well as several cerebrospinal fluid tests for Alzheimer’s.

The Netherlands-based research company Stichting imec Nederland filed for protection of a smart toilet seat for the non-invasive measurement of physiological parameters, and especially for detecting a bowel movement and/or urination, and for characterizing excrement or feces in terms of a firmness level.

Researchers from the U.K. reported seeking protection for a device and method that combines electromyography (EMG) and Raman spectroscopy to improve the diagnostic pathway for patients with neuromuscular disorders, and that may be used as a minimally invasive bedside test of muscle health.

While the U.S. FDA’s final rule for regulation of lab-developed tests (LDTs) has yet to emerge, there is some reason to expect the rule will be met with litigation from clinical lab associations. The FDA’s Jeff Shuren said in remarks to this year’s meeting of the Medical Device Manufacturers Association that there is a legitimate problem with the accuracy of many LDTs, adding that while stakeholders are at liberty to question the FDA’s rulemaking, the agency’s experience in this area indicates that the question of LDT reliability is not up for debate.
