Bluejay Diagnostics shares fall 31% after Thursday’s rise


By Chris Wack


Shares of Bluejay Diagnostics Inc. reversed course on Thursday’s gains, falling 31% to $1.12 a day after it said the Food and Drug Administration had agreed to review its plan to pursue a De Novo bid for his Symphony IL-6 review.

The stock ended Thursday’s session up 26% and hit a 52-week low of 82 cents on March 8.

In written comments to a January submission of an FDA pre-submission information package, the FDA said Bluejay’s Symphony IL-6 test could be considered for the De Novo pathway.

Bluejay said it continues to progress the Symphony IL-6 test toward its planned FDA marketing application, expected by the end of 2022.

If it is determined that a device does not have a legally marketed Class I or Class II device on which to base a determination of substantial equivalence and a device is considered low to moderate risk, the FDA may decide to classify the product candidate as a De Novo application, rather than the more conventional 510(k) marketing application.
