The U.S. FDA reported a pilot program for validation of lab-developed tests (LDTs) used as companion diagnostics, a move that seems an implicit recognition that test kits as CDx products are not the darlings of test developers. The program arrives as the agency is considering rulemaking for regulation of LDTs, however, a combination of developments that promises to roil the already strained relationship between the FDA and clinical labs.

The U.S FDA 510(k) clearance for Corneat Vision Ltd.’s Everpatch is a “safety stamp” for the product, and the “first step’ in the deployment of Corneat’s synthetic tissue substitute technology, which could displace the use of donor and processed tissue, Almog Aley-Raz, CEO of Corneat, told BioWorld. The Corneat Everpatch, for use in ophthalmic surgeries, is the first non-degradable material that seamlessly embeds itself with surrounding tissue avoiding foreign body response often triggered by implanted devices, Aley-Raz claimed.

Whoever said beauty is only skin deep hasn’t looked below to see what Sientra Inc. has made available there recently. The medical aesthetics company now boasts the only tissue expander cleared in the U.S. for exposure to magnetic resonance imaging, an important screening tool for breast reconstruction patients. Sientra’s CTO Denise Dajles told BioWorld the newly cleared Allox2 Pro Tissue Expander builds on the original expander also cleared by the FDA. “No other expander in the market has an MRI compatibility indication because they are based on a metal, i.e., metallic ports and big magnets in them,” Dajles explained.
