FDA

The draft guidelines have intrigued industry players interested in pursuing labeling that would allow their CDx to direct treatment for a class of drugs instead of one drug.

Plans are in place for a Guardant360-based assay to predict response to AsztraZeneca's Tagrisso and for a blood-based TMB test using the larger GuardantOmni panel.

Told to Pause

ScienceInsider reports that US National Institutes of Health researchers were told in the fall they could not obtain new human fetal tissue.

The discussion draft includes the regulatory proposals, including precertification, the FDA provided to legislators in a technical assistance document.

The guidance addresses cases in which there's enough evidence to conclude that the CDx is suitable for use with a specific group or class of oncology therapies.

The US Department of Health and Human Services says it has not cancelled a fetal tissue contract with a University of California, San Francisco, lab, Science reports.

The endorsement is the agency's first through the Human Variant Database Program, for which it released final guidance earlier this year.

The proposal establishes procedures and criteria for the de novo classification of medical devices that would clarify requirements for submission and review.
