Lineage Cell Therapeutics Reports Fourth Quarter and Full Year 2019 Financial Results and Provides Business Update

Lineage Cell Therapeutics, Inc. (NYSE American and TASE: LCTX), a clinical-stage biotechnology company developing novel cell therapies for unmet medical needs, today reported financial and operating results for the fourth quarter and full year ended December 31, 2019. 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 fourth quarter and full year 2019 financial and operating results and to provide a business update.

"2019 was a transformative year for Lineage. We established Lineage as a leading cell therapy company with the goal to usher in a new branch of medicine based on transplanting intact cells into the body to restore activity lost to aging, injury, or disease," stated Brian M. Culley, CEO. "We expanded our clinical pipeline by combining three complementary cell therapy assets under one roof, and also significantly reduced our cash burn by eliminating non-core activities. We focused our priorities and rebranded the company with a new leadership team, name, and headquarters in San Diego County. As we enter 2020, we intend to capitalize on the changes we made in 2019 and continue our positive momentum. Our primary goal is to complete enrollment in our Phase 1/2a clinical trial of OpRegen for dry AMD and collect the data that will guide our late-stage trial design and partnership discussions. We also will continue our efforts to advance the OPC1 program into a randomized trial by introducing commercially enabling enhancements to the manufacturing process. Lastly, we are working with our development partner, Cancer Research UK, and continue to assess clinical data that is being generated from the ongoing Phase 1 trial of VAC2. We are evaluating whether to exercise our option to acquire the data generated in the trial if the data supports that decision. We are excited about the three clinical programs that we are working to advance, each of which represents a potential billion dollar market opportunity."

Significant events and data updates from 2019 and early 2020 include:

• Successfully dosed two patients in our OpRegen Phase 1/2a clinical trial for the treatment of dry age-related macular degeneration (AMD) with a new thaw-and-inject formulation and a new delivery device, the 510(k)-cleared Subretinal Delivery System (SDS) developed by Gyroscope Therapeutics (Gyroscope). The Gyroscope SDS is designed to precisely and consistently deliver therapeutics to the sub-retinal space via a suprachoroidal route, avoiding: (i) the need for a vitrectomy; (ii) perforation of the retina (retinotomy); and (iii) loss of cells and adverse safety events due to efflux. We have to date reported on two patients dosed with the combination of the new device and formulation. The first patient demonstrated notable improvements in vision, having gained 25 readable letters (or 5 lines) 6 months following administration, as assessed by the Early Treatment Diabetic Retinopathy Scale (ETDRS). This represented an improvement in visual acuity from a baseline of 20/250 to 20/100 in the treated eye. The second patient showed a small improvement in visual acuity in the treated eye at just 14 days following treatment. Both patients had rapid healing at the surgical site with no unexpected complications or any serious adverse events. Improvements for patients in the trial have typically become most evident approximately three to six months after treatment. Treatment for all patients in the trial continues to be well tolerated and all five patients in Cohort 4 (who have better baseline vision and less advanced disease than Cohorts 1-3 patients) registered improvement according to the ETDRS eye chart assessment. Improvements ranged from 8 to 25 additional letters correctly identified for all patients with at least 6 months of follow-up as of December 31, 2019. We expect to dose a total of six patients with the Gyroscope SDS under our current agreement with Gyroscope.
• Acquired Asterias Biotherapeutics, Inc. in March 2019. As a result of this acquisition, we acquired two additional cell therapy product candidates, OPC1 and VAC2, along with their associated expansion opportunities and other assets. As we integrated the two companies, we reduced costs by about 50% by eliminating duplicate costs and rationalizing non-key projects.
• Rebranded as Lineage Cell Therapeutics and relocated the corporate headquarters from the San Francisco Bay Area to Carlsbad, California. We also hired experienced biotech professionals to fill critical management positions, including the Chief Financial Officer, General Counsel and Vice President, Business Development.
• Entered into agreements with three separate companies, with each agreement relating to different parts of Lineage's intellectual property portfolio. All three companies have ongoing commercial operations in areas related to cell therapy. The aggregate up-front cash payment from the three transactions was greater than one million dollars with additional cash and royalties due upon reaching certain development milestones or product sales.
• Reported a positive clinical update from our ongoing Phase 1/2a clinical trial of OPC1 known as SCiStar for the treatment of acute spinal cord injury (SCI). The overall safety profile of OPC1 remained excellent with robust motor recovery in the arms/hands maintained through year 2 follow-ups to date. Gains in motor function for patients assessed to date continued, representing tremendously meaningful improvements to quality of life and independence.
• Awarded $3.2 million in grants from the Israel Innovation Authority and the National Institutes of Health and published or presented multiple papers and abstracts describing our work.
• Obtained patents associated with the manufacture of our unique cell types, adding additional protections to all three of our clinical programs. Also obtained patent rights describing the use of induced pluripotent stem cells, an alternate option for generating differentiated cells for transplant and treatment of diseases, further broadening the potential application of our work.
• Granted a Conformité Européenne (CE) Mark for Renevia^®, the Company's facial aesthetics product, with an intended use in adults for the treatment of facial lipoatrophy. The CE Mark enables us to sell Renevia in Europe and we are actively pursuing a commercialization partner for this activity.
• Announced that after reviewing promising preliminary data from the ongoing OpRegen Phase 1/2a clinical trial, our independent data safety monitoring board removed the protocol-mandated treatment stagger. Accordingly, we are opening two new U.S. clinical sites to accelerate patient enrollment and broaden surgical experience among dry AMD experts.

Potential key events for 2020:

• Complete patient enrollment in the U.S. with the Gyroscope SDS in the ongoing Phase 1/2a clinical trial of OpRegen for the treatment of dry AMD.
• Present new OpRegen data from the ongoing Phase 1/2a clinical trial in May 2020 and as available throughout the year.
• Meet with the U.S. Food and Drug Administration (FDA) to discuss the further clinical development of OpRegen.
• Evaluate partnership opportunities for the OpRegen program.
• Enhance commercial utility of OPC1 program by introducing commercially enabling improvements to the manufacturing process in our GMP manufacturing facility.
• Meet with the FDA to discuss the manufacturing and further clinical development of OPC1.
• Provide further clinical updates from the SCiStar Trial for SCI.
• Evaluate partnership opportunities for Renevia in Europe.
• Evaluate VAC2 clinical data from the initial patients in the ongoing Phase 1 trial in NSCLC (non-small cell lung cancer) run by Cancer Research UK and evaluate potential early exercise of option to acquire data.
• Continue engagement with the investment and medical communities with participation at medical and healthcare industry conferences, ongoing throughout 2020.
• Strengthen existing partnerships with the National Institutes of Health, the Israel Innovation Authority, the California Institute for Regenerative Medicine, and Cancer Research UK.

Balance Sheet Highlights

Cash, cash equivalents, and marketable securities totaled $30.7 million as of December 31, 2019. Marketable securities include our remaining ownership of unrestricted securities in OncoCyte, AgeX Therapeutics, and Hadasit Bio-Holdings Ltd (Hadasit).

During 2019, we were able to fund our operations primarily by selling a portion of our marketable securities. We sold 6,250,000 shares of OncoCyte's common stock for net proceeds of approximately $10.7 million. We also sold 765,889 shares of AgeX common stock for net proceeds of approximately $1.8 million and 1,048,147 shares of Hadasit common stock for net proceeds of approximately $1.7 million. On January 2, 2020, we sold 2,383,090 shares of OncoCyte stock for net proceeds of approximately $5.0 million. We continue to hold approximately 6 million shares of OncoCyte stock that are valued at $13.8 million as of March 10, 2020. All of our marketable securities are now in companies in which we hold less than 10% of the outstanding shares.

In conjunction with the sale of AgeX shares to Juvenescence Limited (Juvenescence) in 2018, we also hold a $21.6 million promissory note bearing 7% annual interest that matures on August 30, 2020. As of December 31, 2019, the outstanding principal and accrued interest on the note was $23.6 million. If, prior to August 30, 2020, Juvenescence completes an initial public offering resulting in gross proceeds of at least $50.0 million, the promissory note automatically converts into the Juvenescence securities. Lineage has the right to review Juvenescence's financial statements twice per year.

In summary, as of December 31, 2019, the value of the Company's cash, cash equivalents, marketable securities, and the balance of the Juvenescence promissory note due August 2020 were in excess of $54 million.

The Company has implemented significant cost savings initiatives and anticipates that net operational spend for 2020 will be approximately $16 million. This planned spending level represents a significant reduction from 2019 spending levels of $32 million and 2018 spending levels of $43 million for Lineage and Asterias combined. Lineage acquired Asterias on March 8, 2019. Assuming the Juvenescence note is paid in cash at maturity, the Company believes that it is funded well into 2021 as a result of these cost savings initiatives.
