On Oct. 2, the FDA did two things to enhance the transparency of its CLIA activities.

1. Revised Categorization Guidance
The FDA issued updated guidance providing more details about the procedures it will use to categorize IVDs and respond to applications for CLIA waivers. The key details:

  • The FDA will try to notify sponsors of an approved IVD's categorization within two weeks of approval;
  • IVDs approved for home or over-the-counter use will be waived automatically;
  • Makers of IVDs categorized as moderate complexity can apply for a CLIA waiver;
  • To get the waiver, the maker must use clinical and flex studies to show that the test is simple to use and poses "insignificant risk of an erroneous result."

2. Publication of CLIA Waivers
The second thing the FDA did to beef up transparency is launch a pilot program under which it will publish summaries of its CLIA Waiver by Application (CW) decisions. In addition to enabling the public to see how the FDA reviewed the data, publishing the decision summaries will help test makers prepare their future CW applications, according to the agency.

NOTE TO USERS: To keep you abreast of FDA CLIA waivers, LIR will include CW decision summaries in the monthly FDA Watch column from now on.

Here's a rundown of the other key diagnostic product launches from late August through the third week of September.

A Zika Approval First
On Oct. 6, Roche's Cobas test for detecting Zika virus in plasma specimens of human blood and organ donors the first Zika detection test approved for use by blood collection facilities in screening blood supplies. Although the FDA has issued about two dozen emergency use authorizations for Zika assays, including two new EUAs this month (see chart below), it has yet to greenlight any Zika test for actually diagnosing patients.

Here's a look at key FDA diagnostics approvals in late September through mid-October:

NEW FDA APPROVALS
