Legend Biotech Provides Regulatory Update on Ciltacabtagene Autoleucel (Cilta-Cel)

Legend Biotech Corporation (“Legend Biotech”) announced that the U.S. Food and Drug Administration (the “FDA”) has extended the Prescription Drug User Fee Act (“PDUFA”) target date for ciltacabtagene autoleucel (“cilta-cel”) to February 28, 2022. Cilta-cel is a BCMA-directed chimeric antigen receptor T cell (CAR-T) therapy being investigated for the treatment of adults with relapsed and/or refractory multiple myeloma. The Biologics License Application (BLA) was submitted by Legend Biotech’s collaboration partner Janssen Biotech, Inc. (“Janssen”).

Following an initial notification of the extension on October 28, 2021, Legend and Janssen met with the FDA on November 1, 2021. The extension of the PDUFA date allows sufficient time for the FDA to review information recently submitted pertaining to an updated analytical method following an FDA information request. No additional clinical data have been requested.

This Form 6-K (other than Exhibit 99.1 hereto) is incorporated by reference into the Company’s Registration Statements on Form F-3 (File Nos. 333-257625 and 333-257609) and Form S-8 (File No. 333-239478).

Cautionary Note Regarding Forward-Looking Statements

Statements in this report on Form 6-K about future expectations, plans and prospects, as well as any other statements regarding matters that are not historical facts, constitute “forward-looking statements” within the meaning of The Private Securities Litigation Reform Act of 1995. These statements include, but are not limited to, statements relating to the timing and outcome of regulatory reviews relating to cilta-cel, including the BLA being reviewed by the FDA. The words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “potential,” “predict,” “project,” “should,” “target,” “will,” “would” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. Actual results may differ materially from those indicated by such forward-looking statements as a result of various important factors. Legend Biotech’s expectations could be affected by, among other things, uncertainties involved in the development of new pharmaceutical products; unexpected clinical trial results, including as a result of additional analysis of existing clinical data or unexpected new clinical data; unexpected regulatory actions or delays, including requests for additional safety and/or efficacy data or analysis of data, or government regulation generally; as well as the other factors discussed in the “Risk Factors” section of Legend Biotech’s Annual Report on Form 20-F filed with the Securities and Exchange Commission on April 2, 2021. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those described in this presentation as anticipated, believed, estimated or expected. Legend Biotech specifically disclaims any obligation to update any forward-looking statement, whether as a result of new information, future events or otherwise.
