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 third 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 third quarter 2022 financial and operating results and to provide a business update.

“A single administration of RG6501 (OpRegen^®), a proprietary retinal pigment epithelial cell transplant, across an area of atrophy in advanced AMD patients has shown the potential to slow, stop, or reverse the progression of GA in our phase 1/2a clinical trial. To our knowledge, this is the first intervention that has reported anatomical changes of this magnitude in the field of GA, so we are pleased with the continued progress on RG6501 and the efforts which have been made to initiate its next clinical trial,” stated Brian M. Culley, Lineage CEO. “Looking ahead, our focus turns increasingly to planned regulatory interactions for OPC1 and VAC2, from which we expect to inform and enable their next phases of clinical development in spinal cord injury and oncology, respectively. In parallel, we are advancing our newly launched cell transplant programs in photoreceptors for vision disorders and auditory neurons for hearing loss, with initial preclinical studies from our photoreceptor program currently ongoing and the start of preclinical testing of our auditory neuron program anticipated prior to year-end. We believe that completing these efforts while maintaining our commitment to disciplined spending will help Lineage create shareholder value in the coming year.”

Balance Sheet Highlights

Cash, cash equivalents, and marketable securities totaled $66.4 million as of September 30, 2022, which is expected to support planned operations into Q3 2024.

Third 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 September 30, 2022 were approximately $3.0 million, a net increase of $0.7 million as compared to $2.3 million for the same period in 2021. The increase was driven by collaboration and licensing revenue recognized from deferred revenues from the Roche Agreement, partially offset by less royalty revenues.

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 September 30, 2022 were $8.0 million, a decrease of $0.1 million as compared to $8.1 million for the same period in 2021.

R&D Expenses: R&D expenses for the three months ended September 30, 2022 were $3.6 million, a net increase of $0.8 million as compared to $2.8 million for the same period in 2021. The net increase was primarily driven by higher OpRegen related expenses to support the Roche collaboration.

G&A Expenses: G&A expenses for the three months ended September 30, 2022 were $4.4 million, a net decrease of approximately $0.9 million as compared to $5.3 million for the same period in 2021. The decrease was primarily driven by $1.1 million in lower litigation and legal expenses and $0.3 million in lower investor relations expense, partially offset by a $0.5 million increase in payroll and related benefits expense.

Loss from Operations: Loss from operations for the three months ended September 30, 2022 was $5.2 million, a decrease of $1.6 million as compared to $6.8 million for the same period in 2021.

Other Expenses, Net: Other expenses, net for the three months ended September 30, 2022 reflected other expense, net of $0.3 million, compared to other expense, net of $2.0 million for the same period in 2021. The net change was primarily driven by a decrease in the value of marketable equity securities and 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 September 30, 2022 was $6.1 million, or $0.04 per share (basic and diluted), compared to a net loss attributable to Lineage of $7.8 million, or $0.05 per share (basic and diluted), for the same period in 2021.
