• Positive RG6501 (OpRegen®) Phase 1/2a Clinical Study 36 Month Results Featured at Clinical Trials at the Summit 2025
• Successfully Reduced-to-Practice Critical Aspect of Commercial-Scale, Cell-Based, GMP Production Processes
• First Chronic Patient Treated in New Clinical Study of OPC1 in Patients with Subacute and Chronic Spinal Cord Injury
• Hosted the 3rd Annual SCI Investor Symposium

CARLSBAD, Calif.--(BUSINESS WIRE)-- Lineage Cell Therapeutics, Inc. (NYSE American and TASE: LCTX), a clinical-stage biotechnology company developing novel allogeneic, or “off the shelf”, cell therapies for serious neurological and ophthalmic conditions, today reported its second quarter 2025 financial and operating results and will host a conference call today at 4:30 p.m. Eastern Time to discuss these results and provide a business update.

“Following the recent positive 36-month clinical data update with the OpRegen RPE cell therapy program, which is licensed by Genentech and Roche, we continue to remain confident in its potential to address a significant medical need, especially because long term clinical outcomes following a single administration of OpRegen cell therapy are challenging the long-held view that GA is an irreversible condition,” stated Brian M. Culley, Lineage CEO. “It is notable that among patients who received extensive one-time coverage of OpRegen RPE cells across the area of atrophy, anatomical and functional benefits have lasted for at least three years, outcomes consistent with meaningful disease stabilization and even improvement.”

“In addition to supporting our partners in advancing the OpRegen program, we are equally excited to have reached a milestone with our OPC1 program for the treatment of spinal cord injury, treating our first-ever chronic patient with a new parenchymal spinal delivery system. We also solidified our position as a leader in allogeneic cell process development and manufacturing by reporting in-house GMP production for each of two separate cell-based product candidates from a master and working cell bank system which, in its current form, can support a production capability of several million doses for a single-administration product. This is in addition to continuing to advance our ReSonanceTM program for the treatment of sensorineural hearing loss and evaluating other strategically selected early-stage initiatives. As our cell therapy platforms gain further validation, we believe our pipeline and cell manufacturing and related expertise continue to position us as a compelling partner and investment opportunity,” added Mr. Culley.

Select Business Highlights

• RG6501 (OpRegen Cell Therapy)
  • Positive RG6501 (OpRegen) Phase 1/2a Clinical Study 36 Month Results featured at Clinical Trials at the Summit (CTS) 2025. 2025 CTS highlights:
    • Gains in Best Corrected Visual Acuity (BCVA) in patients in Cohort 4 (less advanced GA) measured at month 12 remain evident through month 36 following subretinal administration of OpRegen cell therapy;
    • Mean change in BCVA among treated eyes for patients (n=10) completing 3-year follow up was +6.2 letters (compared to +5.5 letters at 24 months) (Early Treatment Diabetic Retinopathy Study (ETDRS) assessment);
    • Improvement in BCVA and outer retinal structure in patients with extensive OpRegen bleb coverage of their GA area was greater than in patients with limited coverage and persisted through month 36
    • Effects were greater on average in the five (5) patients with extensive OpRegen cell therapy coverage of atrophic areas at the time of surgical delivery
      • In these patients’ treated eyes, the mean change in BCVA was +9.0 ETDRS letters for those completing 3-year follow-up (compared to +7.4 ETDRS letters at 24 months) (n=5)
    • These data suggest that OpRegen cell therapy may counteract RPE cell dysfunction and loss in GA by providing support to the remaining retinal cells within atrophic areas, and these effects appear durable through at least 36 months after a single administration
      
      
  • Ongoing execution of Lineage’s contributions to its collaboration with Roche and Genentech across multiple functional areas, including support for the ongoing Phase 2a clinical study (the “GAlette Study”) in patients with geographic atrophy (GA) secondary to age-related macular degeneration (AMD) at sites in the U.S. and Israel.
    • In addition to testing of other surgical parameters, Genentech currently plans to evaluate two proprietary surgical delivery devices that have potential advantages over available off-the-shelf devices in the GAlette Study.
      
      
  • Ongoing efforts to further support development of OpRegen RPE cell therapy under a separate services agreement with Genentech, signed May 2024, including: (i) activities to support the ongoing Phase 1/2a study long term follow-up and the currently enrolling Phase 2a GAlette Study; and (ii) additional technical training and materials related to our cell therapy technology platform to support commercial manufacturing strategies.
    
    
• Manufacturing Capability
  • Successfully completed a production run for two different product candidates, each produced from a customized, two-tiered current Good Manufacturing Practice (“cGMP”) cell banking system, highlighting the application of the Lineage platform across multiple programs.
    • This production process utilizes a genetically-stable master cell bank created from a single, well-characterized pluripotent cell line, to generate a working cell bank, which then provides the source material for a final cell-based product candidate.
    • This demonstrated cGMP production process should enable the ability to produce millions of doses of a cost-effective, scalable and consistent supply of an allogeneic, cell-based product derived from a single initial cell line, that can be applied across multiple programs.
      
      
• OPC1
  • First chronic spinal cord injury patient treated in the DOSED (Delivery of Oligodendrocyte Progenitor Cells for Spinal Cord Injury: Evaluation of a Novel Device) clinical study.
    • First chronic SCI patient treated in DOSED was a neurologically complete SCI injury (American Spinal Injury Association Impairment Scale [AIS] grade A), with a single neurological level of injury (NLI) from levels T1 to T10, and the novel delivery system successfully administered a one-time injection of OPC1.
  • Hosted the 3rd Annual Spinal Cord Injury Investor Symposium (3rd SCIIS) in partnership with the Christopher & Dana Reeve Foundation.

Balance Sheet Highlights

Cash, cash equivalents, and marketable securities of $42.3 million as of June 30, 2025, is expected to support planned operations into Q1 2027.

Second Quarter Operating Results

Revenues: Revenue is generated primarily from collaboration revenues, royalties, and other revenues. Total revenues for the three months ended June 30, 2025 were $2.8 million, a net increase of $1.4 million as compared to $1.4 million for the same period in 2024. The increase was primarily driven by more collaboration revenue recognized from deferred revenues under the Roche Agreement, as well as deferred revenues recognized upon termination of the VAC platform-related collaboration 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 June 30, 2025 were $22.5 million, an increase of $15.2 million as compared to $7.3 million for the same period in 2024. The overall increase was driven by the $14.8 million expense recognized for the loss on impairment for the intangible asset related to the VAC platform.

R&D Expenses: R&D expenses for the three months ended June 30, 2025 were $3.1 million, an increase of $0.2 million as compared to $2.9 million for the same period in 2024. The net increase was primarily driven by ongoing activities within our preclinical programs.

G&A Expenses: G&A expenses for the three months ended June 30, 2025 were $4.6 million, an increase of $0.2 million as compared to $4.4 million for the same period in 2024. The net increase was primarily driven by more costs incurred for services provided by third parties.

Loss from Operations: Loss from operations for the three months ended June 30, 2025 were $19.8 million, an increase of $13.9 million as compared to $5.9 million for the same period in 2024. This increase in loss was primarily driven by the impairment expense related to the VAC platform of $14.8 million, which is a non-recurring transaction.

Other Income/(Expenses): Other income/(expenses) for the three months ended June 30, 2025 reflected other expense of $10.6 million, compared to other income of $0.1 million for the same period in 2024. The net change was primarily attributable to the quarterly fair value remeasurement of the warrant liabilities of $12.7 million primarily due to an increase in our share price as compared to the prior quarter, partially offset by $1.7 million for 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, 2025 was $30.5 million, or $0.13 per share (basic and diluted), compared to a net loss of $5.8 million, or $0.03 per share (basic and diluted), for the same period in 2024. The change was primarily driven by the loss on impairment expense related to a 2019 acquisition and the quarterly fair value remeasurement of the warrant liabilities.

About Lineage Cell Therapeutics, Inc.

Lineage Cell Therapeutics is a clinical-stage biotechnology company developing allogeneic, or “off the shelf”, cell therapies for serious neurological and ophthalmic conditions. Lineage’s programs are based on its proprietary cell-based technology platform and associated development and manufacturing capabilities. From this platform, Lineage designs, develops, manufactures, and tests specialized human cells with anatomical and physiological functions similar or identical to cells found naturally in the human body. These cells are created by applying directed differentiation protocols to established, well-characterized, and self-renewing pluripotent cell lines. These protocols generate cells with characteristics associated with specific and desired developmental lineages. Cells derived from such lineages are transplanted into patients in an effort to replace or support cells that are absent or dysfunctional due to degenerative disease, aging, or traumatic injury, and to restore or augment the patient’s functional activity. Lineage’s neuroscience focused pipeline currently includes: (i) OpRegen cell therapy, a retinal pigment epithelial cell therapy in Phase 2a development under a worldwide collaboration with Roche and Genentech, a member of the Roche Group, for the treatment of geographic atrophy secondary to age-related macular degeneration; (ii) OPC1, an oligodendrocyte progenitor cell therapy in Phase 1/2a development for the treatment of spinal cord injuries; (iii) ReSonance (ANP1), an auditory neuronal progenitor cell therapy for the potential treatment of auditory neuropathy; (iv) PNC1, a photoreceptor neural cell therapy for the potential treatment of vision loss due to photoreceptor dysfunction or damage; and (v) RND1, a novel hypoimmune induced pluripotent stem cell line being developed under a gene editing partnership.
