The regulatory clouds that have been darkening the U.S. FDA landscape of late for Uniqure NV’s gene therapy AMT-130 in Huntington’s disease may be parting a bit with the announced departure of Vinay Prasad as director of the agency’s CBER at the end of April.
The U.S. FDA rolled out its anticipated “plausible mechanism” draft guidance, enabling ultrarare disease drug developers to generate evidence of effectiveness and safety to support approval when randomized controlled trials are not possible due to small patient populations.
Moderna Inc. blamed a switcheroo by the U.S. FDA for the refusal-to-file (RTF) letter on the seasonal influenza vaccine mRNA-1010. Shares of the firm (NASDAQ:MRNA) closed Feb. 11 at $40.51, down $1.49, having traded as low as $36.66 as investors learned of the RTF letter, which Moderna said is “inconsistent with feedback” the company was given by regulators during pre-phase III as well as pre-BLA-submission talks.

Moving away from a one-size-fits-all approach, the U.S. FDA's CBER released details Jan. 11 about how it’s leveraging its growing experience with cell and gene therapies (CGTs) to exercise greater regulatory flexibility in chemical, manufacturing and control requirements for the products.
The U.S. FDA’s recent switch toward more routine use of generalist field investigators might be seen in some quarters as an attempt to do more with less, but a session on the topic at the Food and Drug Law Institute’s annual enforcement conference in Washington seems to suggest that this reversal of historic practice presents at least as many problems as solutions for industry.
