FDA reverses its rejection of Regenxbio Navsunli, allowing the company to refile its gene therapy application.

The FDA will reconsider approving Regenxbio's experimental gene therapy for a deadly and rare childhood brain disorder it rejected just four months ago.

Regenxbio plans to resubmit its Hunter syndrome gene therapy RGX-121 after the FDA reversed course, saying existing data are sufficient for accelerated approval review.
