The U.S. Department of Health and Human Services (HHS) has withdrawn its August 2020 rescission of the FDA’s authority to regulate lab-developed tests (LDTs), a reversal predicated on the need for additional testing capacity for the COVID-19 pandemic. However, the non-COVID implications are not clear as the FDA is not widely seen as having the capacity to regulate LDTs for non-pandemic purposes, while pending legislation would dramatically overhaul the agency’s approach to LDT regulation, making the current regulatory environment an unstable environment at best. The FDA accompanied the announcement with a statement that the emphasis at the agency is on tests that do not require that the patient sample be sent to a lab for processing.

The FDA has approved Pharmaessentia Corp.'s Besremi (ropeginterferon alfa-2b) for the rare blood disorder polycythemia vera, the interferon offering an alternative to JAK inhibitor therapy. PV is a rare, chronic and life-threatening blood cancer caused by a mutation in stem cells in the bone marrow, resulting in overproduction of blood cells. Besremi, which is already approved in Taiwan, Europe and South Korea, is a monopegylated, long-acting interferon, which counteracts the effects of the mutated bone marrow cells and is initially taken fortnightly.

The FDA categorized the recall of more than 2.2 million Ellume Pty Ltd. COVID-19 Home Tests that began Oct. 5 as a class I recall, “the most serious type of recall.” While the agency has received significant criticism lately about ambiguity in recalls that often leaves consumers uncertain about their seriousness, the FDA eliminated all doubt on this one saying, “use of these tests may cause serious adverse health consequences or death.” The FDA said it received 35 reports of false positives associated with the antigen test. No deaths have been reported.

The FDA’s device center has revisited the 2005 guidance for the content of premarket submissions for device software functions, a document that puts much more emphasis on risk compared to the legacy 2005 guidance.

U.S. President Joe Biden on Nov. 12 announced his intent to nominate former FDA Commissioner Robert Califf to return to the regulator’s top job. He would take the place of Janet Woodcock, acting commissioner of the agency since Jan. 20.
