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

“Lineage continued to make significant operational and developmental progress during the second quarter, providing additional reports of clinically meaningful outcomes in patients with dry-AMD with geographic atrophy, advancing our OPC1 program for spinal cord injury, and reaching a paid milestone under our new VAC platform alliance,” stated Brian M. Culley, Lineage CEO. “OpRegen has generated the only known cases of retinal tissue restoration in previously confirmed atrophic areas in humans, and as importantly, has provided a durable functional benefit of improved visual acuity in the treated eyes of the majority of better vision, earlier-stage patients. We are excited that we soon will be returning OPC1 to clinical testing in a device safety study, which will include chronic spinal cord injury patients, and look forward to collaborating with the SCI community as part of our efforts to improve outcomes for individuals with this debilitating condition. We also believe being added to the Russell 3000^® Index will improve awareness of the continued success of our cell transplant approach and that our current cash and cash equivalents provide funding to reach additional value-creating milestones in the months and years ahead.”

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

- Reported a positive interim clinical update from the ongoing Phase 1/2a study of OpRegen for the treatment of dry-AMD with GA: 83% of all Cohort 4 patients exhibited stable or improved Best Corrected Visual Acuity at least 6 months post-treatment, while visual acuity declined in the majority of untreated eyes; notably, the first retinal restoration patient, with confirmed atrophy growth at baseline has had zero progression for almost three full years;

- Reported two additional cases of retinal tissue restoration in dry AMD patients treated with OpRegen; restoration has now been observed in three of four patients who received OpRegen RPE cells across a wide area of atrophy;

- Hosted a webinar with key therapeutic area experts to discuss the reported evidence of retinal tissue restoration findings in detail, including a review of anatomical improvements, functional activity, and additional results of treatment with OpRegen;

- Reported that the Company has been added to both the Russell 3000^® as well as the Russell Microcap^® Indexes;

- Reported that OPC1 will return to clinical testing; a Phase 1 clinical study will evaluate a novel delivery system in partnership with Neurgain Technologies and will include treatment of chronic spinal cord injury patients. The Phase 1 study is intended to validate the delivery system for use in a late-stage clinical study, expected to begin in 2022;

- 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;

- Announced an exclusive option agreement with Amasa Therapeutics for the supply and use of clinical-grade HyStem^® for the development and commercialization of therapies for local treatment of solid tumors; and

- Announced the appointment of Kevin L. Cook as Chief Financial Officer. Mr. Cook brings broad expertise across a range of financial matters and has executed over $30 billion of capital raising and corporate development transactions, approximately half of which involved life sciences companies.

Some of the events and milestones to look forward to include:

- OpRegen Program

• Presentation of additional interim data from the Phase 1/2a study, anticipated during the third and fourth quarters of 2021;
• Meeting with the U.S. Food and Drug Administration (FDA) to discuss further clinical development, anticipated in the fourth quarter of 2021.

- OPC1 Program

• Evaluation of the Neurgain Parenchymal Spinal Delivery (PSD) system in preclinical and clinical testing;
• GMP production of OPC1 via an improved manufacturing process and release testing to support a late-stage clinical trial;
• FDA interaction to discuss manufacturing improvements, anticipated around the end of 2021 or early 2022.

- VAC Program

• Completion of enrollment in the ongoing VAC2 Phase 1 non-small cell lung cancer study;
• Reporting results from the ongoing VAC2 Phase 1 study;
• Evaluation of opportunities for new VAC product candidates based on internally identified or partnered tumor antigens.

- Continued evaluation of partnership opportunities and expansion of existing external collaborations and identification of new collaborations.

Balance Sheet Highlights

Cash, cash equivalents and marketable securities totaled $68.7 million as of June 30, 2021. Marketable securities of $6.7 million as of June 30, 2021 include the Company’s remaining ownership in OncoCyte and Hadasit Bio-Holdings Ltd.

Second Quarter Operating Results

Revenues: Lineage’s revenue is generated primarily from research grants, royalties, and licensing fees. Total revenues for the three months ended June 30, 2021 were approximately $0.5 million, an increase of $0.1 million as compared to $0.4 million for the same period in 2020. The increase was primarily related to a $0.2 million increase in licensing revenues in connection with the new collaborative agreement with Immunomic Therapeutics, and a $0.1 million increase in royalties, partially offset by a $0.2 million decrease in grant revenues, primarily driven by the completion of NIH grant-activities in the prior year.

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 June 30, 2021 were $7.5 million, an increase of $0.8 million as compared to $6.7 million for the same period in 2020.

R&D Expenses: R&D expenses for the three months ended June 30, 2021 were $2.9 million, an increase of approximately $0.1 million as compared to $2.8 million for the same period in 2020. The increase was primarily related to increases of $0.3 million and $0.2 million in OPC1 and VAC program expenses, respectively, partially offset by a net decrease of $0.4 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 June 30, 2021 were $4.5 million, an increase of approximately $0.6 million as compared to $3.9 million for the same period in 2020. The increase was primarily attributable to increases of $0.3 million in litigation and other expenses related to Lineage’s merger with Asterias Biotherapeutics, Inc., $0.3 million in investor and public relations expenses, and $0.1 million in legal and patent expenses, partially offset by a $0.1 million decrease in rent and utilities expenses.

Loss from Operations: Loss from operations for the three months ended June 30, 2021 was approximately $7.1 million, an increase of $0.7 million as compared to $6.4 million for the same period in 2020.

Other Income/(Expenses), Net: Other income/(expenses), net for the three months ended June 30, 2021 reflected other income, net of $2.1 million, compared to other expense, net of ($0.1) million for the same period in 2020. The variance was primarily related to an increase in the value of Lineage’s OncoCyte shares and the gain on extinguishment of debt from Lineage’s Paycheck Protection Program loan forgiveness, partially offset by no sales of marketable equity securities as compared to the prior year’s quarter, as well as 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 June 30, 2021 was $4.8 million, or $0.03 per share (basic and diluted), compared to a net loss attributable to Lineage of $6.5 million, or $0.04 per share (basic and diluted), for the same period in 2020.
