Abeona Therapeutics announced today that the US Food and Drug Administration (FDA) has accepted its resubmitted Biologics License Application (BLA) for prademagene zamikeracel (pz-cel) for the treatment of recessive dystrophic epidermolysis bullosa.1

The FDA has established a Prescription Drug User Fee Act (PDUFA) target action date of April 29, 2025.

Abeona's initial BLA for the COL7A1 gene-corrected epidermal sheets was submitted to the FDA in September 2023.2 The FDA accepted the BLA and granted it priority review the following month, establishing an initial PDUFA date of May 24, 2024.3

However, earlier this year, the FDA issued a Complete Response Letter in response to the BLA4 just one month shy of the anticipated target action date.

The FDA identified the need for additional Chemistry, Manufacturing, and Controls information, including validation for specific manufacturing and release testing methods noted during the pre-license inspection. However, the CRL did not find deficiencies in the clinical efficacy or safety data of pz-cel.

Last month, Abeona resubmitted its BLA for pz-cel.5

The BLA's acceptance is based on positive data from the pivotal phase 3 VIITAL study (NCT04227106) and supporting phase 1/2a data (NCT01263379), which demonstrated sustained wound healing and pain reduction with pz-cel.

"The FDA acceptance of our BLA resubmission moves us one step closer to providing pz-cel as a differentiated treatment option to address the persistent unmet needs of people with RDEB in the US," said Vish Seshadri, chief executive officer of Abeona, in a news release.1 "We look forward to continuing to work with the FDA to finalize the review of the pz-cel application."
