Sangamo Therapeutics Advances Rolling Submission Of Its Biologics License Application To FDA For Accelerated Approval Of Isaralgagene Civaparvovec

Sangamo Therapeutics, Inc. (Nasdaq: SGMO), a genomic medicine company, today announced advancement of the rolling submission of a BLA to the FDA seeking accelerated approval of isaralgagene civaparvovec, or ST-920, a wholly owned investigational gene therapy for the treatment of adults with Fabry disease.

Following initiation of the rolling submission in December 2025, Sangamo has now submitted the preclinical and clinical modules to the FDA for review. Rolling submission allows for completed modules of the BLA to be submitted and reviewed by the FDA on an ongoing basis rather than waiting for the entire BLA to be submitted at once. In addition, the antibody assay companion diagnostic, which is designed to screen patients for eligibility with isaralgagene civaparvovec, has been submitted to, and accepted by, the FDA's Center for Devices and Radiological Health (CDRH) seeking Premarket Approval (PMA).
