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 2021. Lineage will host a conference call today at 4:30 p.m. Eastern Time to discuss its first quarter 2021 financial results and to provide a business update.

“Lineage reported significant operational progress with each of its three clinical programs during the first quarter and beyond, delivering not only continued positive clinical results with OpRegen for the treatment of dry-AMD with GA, but also validating partnerships to support our OPC1 and VAC programs,” stated Brian M. Culley, Lineage CEO. “We remain encouraged by the totality of the OpRegen clinical data presented to date, which is suggestive of clinically meaningful benefits, especially in earlier stage disease dry-AMD patients. Moreover, the strategic collaborations we announced for OPC1 and VAC reflect our commitment to a comprehensive asset management approach and add external validation to the potential of our platform to create positive outcomes for patients. Additionally, the capital we brought in during the first quarter ensures that we not only are well funded to reach additional milestones, but also provide us with optionality with respect to partnership discussions.”

Some of the significant events and milestones achieved to date this year include:

- Presented a positive interim clinical update from the ongoing Phase 1/2a study of OpRegen for the treatment of dry-AMD with GA at the 2021 Association for Research in Vision and Ophthalmology Meeting: 83% of all Cohort 4 patients exhibited stable or improved Best Corrected Visual Acuity (BCVA) while visual acuity declined in the majority of untreated eyes;

- Reported that the first known finding of retinal tissue restoration in a patient who received a retinal pigment epithelium (RPE) cell transplant continues to demonstrate areas of retinal restoration as of their last assessment, approximately 3 years after treatment;

- Treated a vitelliform maculopathy patient with OpRegen under named patient compassionate use: the delivery of OpRegen RPE cells via pars plana vitrectomy (PPV) was successful, with no complications arising during the procedure and the patient remains in follow-up;

- Entered into a worldwide license agreement with Immunomic Therapeutics for an allogeneic cell-based cancer immunotherapy based on Lineage’s VAC platform with a total of $2 million in upfront payments anticipated in the first year and the potential for $67 million in development and commercial milestones;

- Entered into an exclusive agreement with Neurgain Technologies to evaluate a novel delivery system for OPC1 for treatment of spinal cord injury;

- Announced the appointment of Anula Jayasuriya, M.D., Ph.D., M.B.A., a successful healthcare private equity executive and venture capitalist with extensive clinical, industry, entrepreneurial, and investment experience, to the Company’s Board of Directors; and

- Announced the appointment of Dr. Dipti Amin, MBBS, a medically trained senior executive with broad expertise in medicine, pharmacology, healthcare, research, and product development, to the Company’s Board of Directors.

Some of the events and milestones to look forward to during the remainder of 2021 include:

- OpRegen Program

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, 2021 were approximately $0.4 million, a decrease of $0.1 million as compared to $0.5 million for the same period in 2020. The decrease was primarily related to an approximate $0.2 million decrease in grant income, which was primarily driven by the completion of SBIR grant-related activities, offset by a $0.1 million increase in royalty-related 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 March 31, 2021 were $7.3 million, a decrease of $0.6 million as compared to $7.9 million for the same period in 2020.

R&D Expenses: R&D expenses for the three months ended March 31, 2021 were $3.4 million, an increase of approximately $0.1 million as compared to $3.3 million for the same period in 2020. The overall increase was primarily related to increases of $0.5 million and $0.4 million in VAC and OPC1 program expenses, respectively, and a net decrease of $0.8 million in OpRegen and other ophthalmic application expenses, primarily driven by fluctuations in the timing of manufacturing activities.

G&A Expenses: G&A expenses for the three months ended March 31, 2021 were $3.9 million, a decrease of approximately $0.6 million as compared to $4.5 million for the same period in 2020. The decrease was primarily attributable to decreases of $0.4 million in expenses related to our merger with Asterias Biotherapeutics, Inc., $0.2 million in rent expense and utilities, $0.1 million in legal and patent expenses, and $0.1 million in compensation expense, offset by a $0.2 million increase in investor and public relations expenses.

Loss from Operations: Loss from operations for the three months ended March 31, 2021 was approximately $7.0 million, a decrease of $0.4 million as compared to $7.4 million for the same period in 2020.

Other Income/(Expenses), Net: Other income/(expenses), net for the three months ended March 31, 2021 reflected other income, net of $5.6 million, compared to other expense, net of ($1.0) million for the same period in 2020. The variance was primarily related to the gain on sale of marketable securities and changes in the value of marketable equity securities for the applicable periods, as well as exchange rate fluctuations related to Lineage’s international subsidiaries. The increase in the value of Lineage’s OncoCyte shares and subsequent sales during the first quarter 2021 contributed significantly to the overall net increase in other income.

Net loss attributable to Lineage: The net loss attributable to Lineage for the three months ended March 31, 2021 was $1.4 million, or $0.01 per share (basic and diluted), compared to a net loss attributable to Lineage of $8.4 million, or $0.06 per share (basic and diluted), for the same period in 2020.
