CARLSBAD, Calif. / May 11, 2023 / Business Wire / Lineage Cell Therapeutics, Inc. (NYSE American and TASE: LCTX), a clinical-stage biotechnology company developing allogeneic cell therapies for unmet medical needs, today reported financial and operating results for the first quarter ended March 31, 2023 and will host a conference call today at 4:30 p.m. Eastern Time to discuss these results.

“During the first quarter of this year, the Lineage team executed on multiple fronts, advancing our clinical and preclinical cell transplant programs while continuing support of our existing alliances and establishing new ones,” stated Brian M. Culley, Lineage CEO. “A key area of focus was our partnership with Roche and Genentech and supporting the ongoing Phase 2a clinical study of OpRegen in patients with GA secondary to AMD, which is enrolling and treating patients at multiple sites in the U.S. Through presentations at various medical and scientific conferences, we also broadened our efforts to enhance awareness of OpRegen’s potential to provide durable anatomical and functional improvements in dry AMD patients. In addition, we established new collaborations with CIRM and the Christopher & Dana Reeve Foundation to support a new SCI conference which aims to identify, discuss, and address gaps in the product development process and elevate the patient’s voice in the treatment process. Looking ahead, we will be working on regulatory interactions for OPC1 while continuing to maintain our commitment to disciplined spending and making responsible investments in disease settings where we believe the use of differentiated cell transplants can provide a meaningful impact for patients.”

Balance Sheet Highlights

Cash, cash equivalents, and marketable securities totaled $46.8 million as of March 31, 2023, which is expected to support planned operations into Q3 2024.

First Quarter Operating Results

Revenues: Lineage’s revenue is generated primarily from licensing fees, royalties, collaboration revenues, and research grants. Total revenues for the three months ended March 31, 2023 were approximately $2.4 million, a net decrease of $2.8 million as compared to $5.2 million for the same period in 2022. The decrease was driven by less collaboration and licensing revenue recognized from deferred revenues from the Roche Agreement.

Operating Expenses: Operating expenses are comprised of research and development (“R&D”) expenses and general and administrative (“G&A”) expenses. Total operating expenses for the three months ended March 31, 2023 were $8.9 million, a decrease of $2.5 million as compared to $11.4 million for the same period in 2022.

R&D Expenses: R&D expenses for the three months ended March 31, 2023 were $4.2 million, a net increase of $1.2 million as compared to $3.0 million for the same period in 2022. The net increase was primarily driven by $0.5 million for nonclinical-related expenses to support the OPC1 program, and $0.2 million in OpRegen program expenses to support the Roche collaboration. Another $0.4 million and $0.2 million of the increase was related to R&D spending on the new auditory neuron and photoreceptor cell therapy programs, respectively.

G&A Expenses: G&A expenses for the three months ended March 31, 2023 were $4.7 million, a net decrease of $3.7 million as compared to approximately $8.4 million for the same period in 2022. The decrease was primarily driven by $3.5 million in lower litigation and legal expenses, mostly due to the Asterias litigation settlement expense accrued in the prior year, and $0.2 million in lower expense for accounting and tax services.

Loss from Operations: Loss from operations for the three months ended March 31, 2023 was $6.6 million, an increase of $0.2 million as compared to $6.4 million for the same period in 2022.

Other Income/(Expenses), Net: Other income (expenses), net for the three months ended March 31, 2023 reflected other income, net of $0.4 million, compared to other expense, net of ($0.7) million for the same period in 2022. The net income was primarily driven by fair market value changes in marketable equity securities, interest income from our marketable debt securities, and other income recorded in the current period related to the employee retention credit program, partially offset by exchange rate fluctuations related to Lineage’s international subsidiaries.

Net Loss Attributable to Lineage: The net loss attributable to Lineage for the three months ended March 31, 2023 was $4.4 million, or $0.03 per share (basic and diluted), compared to a net loss attributable to Lineage of $7.1 million, or $0.04 per share (basic and diluted), for the same period in 2022.
