Legend Biotech Corporation (NASDAQ: LEGN) (Legend Biotech), a global, clinical-stage biotechnology company developing and manufacturing novel therapies, today reported its 2021 third quarter unaudited financial results.

“It continues to be a banner year for us, as we launch our clinical trial in the US for the T cell lymphoma program and see promising developments in our pipeline,” said Ying Huang, PhD, CEO and CFO of Legend Biotech. “We intend to close the year on a strong note by presenting new and updated results from our CARTITUDE Clinical Development Program at the 63rd American Society of Hematology Annual Meeting next month and work to bring cilta-cel to more patients.”

Recent Highlights

• In October 2021, Legend Biotech and its collaboration partner Janssen Biotech, Inc. (Janssen) completed the enrollment of the Phase 3 CARTITUDE-4 study, evaluating cilta-cel in patients with multiple myeloma who have received 1-3 prior lines of therapy including a proteasome inhibitor and immunomodulatory agent and are refractory to lenalidomide. The purpose of this study is to compare the efficacy of cilta-cel with standard therapy – either pomalidomide, bortezomib and dexamethasone (PVd) or daratumumab, pomalidomide and dexamethasone (DPd).
• The U.S. FDA has extended the PDUFA target date for cilta-cel by three months to February 28, 2022. The extension allows the FDA sufficient time to review information recently submitted pertaining to an updated analytical method following an FDA information request.
• On October 18, 2021, Legend Biotech hosted its first Research & Development (R&D) Day in New York, sharing updates on Legend Biotech’s pipeline advancements, including expanded capabilities in cell therapy, and milestones in the cilta-cel clinical development program. The Legend Biotech pipeline has been updated to reflect the disclosures made at this event, including the targets for two of the company’s investigational autologous CAR-T therapies, LB2101 and LB2102. Additionally, the investigator-initiated clinical trial in China evaluating an investigational autologous CAR-T targeting CD33 and CLL-1 for the treatment of acute myeloid leukemia has been removed. The Phase I dose escalation study showed a lack of CAR-T expansion and efficacy.
• In September 2021, the Phase 1, open-label, multicenter clinical trial began in the United States for LB1901, an investigational autologous CD4-targeted CAR-T therapy for the treatment of adults with relapsed or refractory peripheral T-cell lymphoma (PTCL) or cutaneous T-cell lymphoma (CTCL). The primary objectives of the trial are to characterize the safety and tolerability of LB1901 and determine the optimal dose.

Financial Results for the Three-month and Nine-month Periods Ended September 30, 2021

Cash and Cash Equivalents and Time Deposits

As of September 30, 2021, Legend Biotech had approximately $636.0 million of cash and cash equivalents, interest yielding securities and time deposits.

Revenue

Revenue for the three months ended September 30, 2021 was $16.9 million compared to $11.7 million for the three months ended September 30, 2020. $2.2 million out of the increase of $5.2 million was due to two additional milestones achieved pursuant to Legend Biotech’s agreement with Janssen in the fourth quarter of 2020 and in the second quarter of 2021, respectively. The remaining $3.0 million increase in revenue was consideration for the exclusive licensing of patents to Nanjing Probio Biotech Co., Ltd (Probio), a related party controlled by Legend Biotech’s majority shareholder, Genscript Corporation, and affiliates of Probio in September 2021.

Revenue for the nine months ended September 30, 2021 was $50.8 million compared to $34.9 million for the nine months ended September 30, 2020.

Milestone payments are constrained and only included as customer consideration for revenue recognition when it is highly probable that the associated milestone will be achieved, typically when the triggering event occurs. This resulted in an increase in revenue recognized in 2021.

Legend Biotech has not generated any revenue from product sales to date.

Research and Development Expenses

Research and development expenses for the three months ended September 30, 2021 were $72.3 million compared to $63.7 million for the three months ended September 30, 2020.

Other Income and Gains

Other income and gains for the three months ended September 30, 2021 was $0.6 million compared to $1.5 million for the three months ended September 30, 2020. Other income and gains for the nine months ended September 30, 2021 was $2.3 million compared to $5.3 million for the nine months ended September 30, 2020. The decrease of $0.9 million and $3.0 million, respectively, primarily resulted from lower government grant and interest income earned during the three- and nine-month periods ended September 30, 2021, as compared to the corresponding prior year periods.

Other Expenses

Other expenses for the three months ended September 30, 2021 was $2.5 million compared to $1.2 million for the three months ended September 30, 2020. The increase of $1.3 million was primarily due to higher foreign currency exchange loss. Other expenses for the nine months ended September 30, 2021 was $6.9 million compared to $1.3 million for the nine months ended September 30, 2020. The increase of $5.6 million was primarily due to higher foreign currency exchange loss, loss from disposal of assets and other expenses during the nine months ended September 30, 2021.

Finance Costs

Finance costs for the nine months ended September 30, 2021 was $0.3 million compared to $4.2 million for the nine months ended September 30, 2020. The decrease was primarily due to finance costs related to the issuance of convertible redeemable preferred shares in 2020, which were fully converted into ordinary shares upon the completion of Legend Biotech’s initial public offering in June 2020.

Fair Value Loss of Warrant Liability

Fair value loss of warrant liability for the nine months ended September 30, 2021 was $37.4 million caused by changes in fair value of a warrant, which was issued to an institutional investor through a private placement transaction in May 2021. Concurrently, ordinary shares were sold to the same institutional investor in a private placement transaction. The warrant was assessed as a financial liability with a fair value of $119.1 million as of September 30, 2021 and a fair value loss of $35.8 million was recorded for the three months ended of September 30, 2021.

Fair Value Loss of Convertible Redeemable Preferred Shares

For the nine months ended September 30, 2020, Legend Biotech reported a one-time non-cash charge of $80.0 million caused by changes of fair value of Series A convertible redeemable preferred shares (Series A Preferred Shares). Upon consummation of Legend Biotech’s U.S. initial public offering, all outstanding Series Preferred Shares were converted into ordinary shares of Legend Biotech and all accrued but unpaid dividends were settled in the form of ordinary shares of Legend Biotech.

Loss for the Period

About the Cilta-cel Clinical Development Program

CARTITUDE-1 (NCT03548207) is a Phase 1b/2, open-label, multicenter study evaluating the safety and efficacy of cilta-cel in adults with relapsed and/or refractory multiple myeloma who have received at least three prior lines of therapy or are double refractory to an immunomodulatory drug (IMiD) and a proteasome inhibitor (PI), received an IMiD, a PI and an anti-CD38 antibody, and documented disease progression within 12 months of starting the most recent therapy. The primary objective of the Phase 1b portion of the study was to characterize the safety and confirm the dose of cilta-cel, informed by the first in-human study with LCAR-B38M CAR-T cells (LEGEND-2). The Phase 2 portion further evaluated the efficacy of cilta-cel with overall response rate as the primary endpoint.

CARTITUDE-2 (NCT04133636) is a global, multi-cohort Phase 2 study evaluating cilta-cel in patients with multiple myeloma in various clinical settings. Cohort A included patients who had progressive multiple myeloma after 1–3 prior lines of therapy, including PI and IMiD, were lenalidomide refractory, and had no prior exposure to BCMA-targeting agents. Cohort B included patients with early relapse after initial therapy that included a PI and IMiD. Cohort C included patients with RRMM who had been previously treated with a PI, an IMiD, an anti-CD38 monoclonal antibody and B-cell maturation antigen (BCMA)-directed therapy and had no prior treatment with chimeric antigen receptor T (CAR-T) therapy directed at any target. Cohort D included patients with NDMM per IMWG with a history of 4 to 8 total cycles of initial therapy, including induction, high-dose therapy, and ASCT with or without consolidation, and had no prior exposure to BCMA-targeting agents. Cohort E included patients who had NDMM without prior therapy and classified as high risk. Cohort F included patients with a documented efficacy response of very good partial response (VGPR) or better, without progressive disease prior to enrollment, as assessed per IMWG 2016 criteria, and had no prior exposure to BCMA-targeting agents. This study is being conducted to evaluate the overall minimal residual disease (MRD) negative rate of participants who receive cilta-cel.

CARTITUDE-4 (NCT04181827) is a global, randomized Phase 3 study, evaluating cilta-cel in patients with multiple myeloma who have received 1-3 prior lines of therapy including a PI and IMiD and are refractory to lenalidomide. The study is being conducted to evaluate the efficacy of cilta-cel compared to standard therapies including daratumumab, pomalidomide and low-dose dexamethasone (DPd) or pomalidomide, bortezomib and low-dose dexamethasone (PVd).

CARTITUDE-5 (NCT04923893) is a global, randomized Phase 3 open-label study evaluating cilta-cel in patients with newly diagnosed MM for whom autologous stem cell transplant (ASCT) is not planned as initial therapy. The study is being conducted to evaluate the efficacy of bortezomib, lenalidomide and dexamethasone (VRd) followed by cilta-cel vs. VRd followed by Rd maintenance.
