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 of 2022. Lineage management will host a conference call and webcast today at 4:30 p.m. Eastern Time/1:30 p.m. Pacific Time to discuss its first quarter 2022 financial and operating results and to provide a business update.

“The first quarter of this year was highlighted by the rapid launch of new cell therapy programs in hearing loss and vision disorders and conducting tech transfer activities to support our alliance with Roche and Genentech for our dry AMD program,” stated Brian M. Culley, Lineage CEO. “Our broad strategic plan is to position Lineage as a leader in regenerative medicine through the transplant of specific cell types to treat significant unmet medical needs. As part of that plan, we have expanded our cell therapy pipeline to five distinct programs, each offering an opportunity to impact various diseases. We believe our ability to, in just a matter of months, advance from a product concept to generating new intellectual property to support the manufacture of specific cell types, is not only illustrative of the power and efficiency of our platform but also a competitive advantage compared to others in this field. Looking forward, our focus is on clinical and regulatory execution across our portfolio. We are working to advance OPC1 and VAC2 into their next phases of clinical testing, in spinal cord injury and oncology, respectively, as well as advancing our auditory neuron and photoreceptor programs through preclinical development and toward pre-IND meetings with FDA. We believe the combination of our disciplined use of capital and current balance sheet will support multiple years of progress, during which we anticipate reaching significant events with each of our clinical and preclinical programs.”

Recent milestones include:

• Reported RG6501 (OpRegen) Phase 1/2a clinical results at 2022 Association for Research in Vision and Ophthalmology, Inc. (ARVO) annual meeting: 12-month primary endpoint data support the potential for OpRegen to slow, stop or reverse disease progression in geographic atrophy (GA) secondary to age-related macular degeneration (AMD); outer retinal structure improvement observed in five dry AMD patients;
• Announced expansion of pipeline with addition of new cell therapy program: allogeneic photoreceptor neural cell (PNC1) transplants for the treatment of diseases which may lead to blindness; dynamic culturing process offers path to clinical- and industrial-scale production of photoreceptors; data generated further demonstrated that a single cell suspension of photoreceptor precursor cells has the potential to survive and mature post-transplantation in a rodent model of retinal degeneration;
• Announced completion of patient enrollment in Phase 1 clinical study of VAC2 for the treatment of non-small cell lung cancer (NSCLC) by Cancer Research UK; Lineage has now assumed responsibility for further clinical development of VAC2 and any future development opportunities derived from the VAC platform; and
• Announced expansion of pipeline with addition of new cell therapy program: auditory neuronal cells (ANP1) for the treatment of hearing loss; intellectual property filed covering composition and methods for generating auditory neuronal progenitors.

Some of the events and milestones anticipated by Lineage in the rest of 2022 include:

• Investigational New Drug (“IND”) amendment submission to enable clinical performance and safety testing of a novel parenchymal spinal delivery system for OPC1, in Q4 2022;
• FDA interaction to discuss recent manufacturing improvements made to OPC1, anticipated in Q4 2022;
• Clinical data update from the ongoing VAC2 Phase 1 non-small cell lung cancer study; anticipated from CRUK in 2H 2022;
• An IND submission for VAC2 to support US-based clinical testing in 2H 2022;
• Preclinical activities for both ANP1 and PNC1 programs; ongoing throughout 2022;
• Additional OPC1 publications, including full clinical study results from the SCiStar clinical study and an MRI findings paper; anticipated in 2H 2022;
• Continued development of a cell-based therapeutic for glioblastoma with our strategic partner, Immunomic Therapeutics; ongoing throughout 2022;
• Evaluation of opportunities for new VAC product candidates based on internally identified or partnered tumor antigens; ongoing throughout 2022;
• Evaluation of new funded partnership opportunities and/or expansion of existing collaborations; ongoing throughout 2022; and
• Continued participation in numerous investor and partnering meetings and medical and industry conferences to broaden awareness of our mission and accomplishments.

Balance Sheet Highlights

Cash and cash equivalents totaled $78.1 million as of March 31, 2022.

First Quarter Operating Results

Revenues: Lineage’s revenue is generated primarily from research grants, royalties, and licensing fees. Total revenues for the three months ended March 31, 2022 were $5.2 million, an increase of $4.8 million as compared to $0.4 million for the same period in 2021. The increase was primarily related to licensing fees recognized from deferred revenues in connection with the $50.0 million upfront licensing payment received in the first quarter of 2022 from Roche.

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, 2022 were $11.5 million, an increase of $4.2 million as compared to $7.3 million for the same period in 2021, primarily attributable to a $3.5 million non-recurring expense related to the potential settlement of the litigation concerning our 2019 acquisition of Asterias (“Asterias Litigation”).

R&D Expenses: R&D expenses for the three months ended March 31, 2022 were $3.0 million, a decrease of $0.4 million as compared to $3.4 million for the same period in 2021. The decrease was driven by $0.7 million in lower expenses for the OPC1 program, partially offset by $0.2 million and $0.1 million in higher expenses to support the VAC program and OpRegen related expenses to support the Roche Collaboration, respectively. Another $0.1 million of the offsetting increase was related to initial costs to support the new auditory neuron cell therapy program.

G&A Expenses: G&A expenses for the three months ended March 31, 2022 were $8.5 million, an increase of $4.6 million as compared to $3.9 million for the same period in 2021. The increase was primarily attributable to the $3.5 million non-recurring expense related to the potential settlement of the Asterias Litigation, and $0.5 million in share-based compensation.

Loss from Operations: Loss from operations for the three months ended March 31, 2022 was $6.4 million, a decrease of $0.7 million as compared to $7.1 million for the same period in 2021.

Other Income/(Expenses), Net: Other income (expenses), net for the three months ended March 31, 2022 reflected other expense, net of ($0.7) million, compared to other income, net of $5.6 million for the same period in 2021. The net change of ($6.3) million was primarily related to the gain on sale of marketable securities in the prior year.

Net Loss Attributable to Lineage: The net loss attributable to Lineage for the three months ended March 31, 2022 was $7.1 million, or $0.04 per share (basic and diluted), compared to a net loss attributable to Lineage of $1.4 million, or $0.01 per share (basic and diluted), for the same period in 2021.
