SGMO Sangamo Therapeutics Inc

Continued to advance our prioritized neurology genomic medicine pipeline towards the clinic.

Announced two neurology license agreements with blue-chip pharma companies, including a global epigenetic regulation and capsid delivery license agreement with Genentech in August 2024 to develop novel genomic medicines for neurodegenerative diseases and a capsid license agreement with Astellas in December 2024 to deliver genomic medicines for up to five neurological disease targets.

Raised over $100 million in funding in 2024 through non-dilutive license fees and milestone payments, as well as equity financing.

Investigational new drug (IND) application cleared by U.S. Food and Drug Administration (FDA) for ST-503 for treatment of intractable pain due to idiopathic small fiber neuropathy (iSFN), a type of chronic neuropathic pain. Expect to commence patient enrollment and dosing in mid-2025.

Demonstrated nonclinical proof of concept in prion disease. A single intravenous infusion of Sangamo’s zinc finger repressor (ZFR) significantly reduced expression of prion mRNA and protein in the mouse brain and extended mouse survival.

Aligned with FDA on clear regulatory pathway to Accelerated Approval for isaralgagene civaparvovec in Fabry disease, using expected data from ongoing Phase 1/2 STAAR study, avoiding requirement for additional registrational study and accelerating estimated time to potential approval by approximately three years.

Announced updated Phase 1/2 STAAR study data that showed sustained benefit, improvements in kidney function and favorable safety profile.

Sangamo Therapeutics, Inc. (Nasdaq: SGMO), a genomic medicine company, today reported recent business highlights and fourth quarter and full year 2024 financial results.

“I am pleased with Sangamo’s pipeline progress since the start of 2024. We advanced our two prioritized neurology therapies towards the clinic, securing our first ever neurology IND; we showed we are a collaborator of choice for neurotropic capsids, with the announcement of two blue-chip pharma agreements for our STAC-BBB capsid, with negotiations advancing for a third potential agreement; and we have a clear regulatory pathway to Accelerated Approval in Fabry disease, which could reduce the time to potential approval by approximately three years,” said Sandy Macrae, Chief Executive Officer of Sangamo Therapeutics. “We believe our neurology pipeline represents important potential value. In addition, we continue to engage in Fabry business development negotiations, in an effort to capitalize the business for the future. This will be an important year for the Company as we plan to begin patient enrollment and dosing in mid-2025 for our clinical study in iSFN, which we believe has the potential to transform the chronic neuropathic pain landscape, and as we prepare for an anticipated BLA submission in Fabry disease in the second half of the year.”

Recent Business Highlights

Corporate Updates

• Announced in December a capsid license agreement with Astellas Gene Therapies, Inc. (Astellas) to deliver genomic medicines for neurological diseases. Agreement grants Astellas a worldwide exclusive license to STAC-BBB for up to five potential neurological disease targets. Received a $20 million upfront license fee from Astellas and eligible to earn up to $1.3 billion in additional licensed target fees and milestone payments across all five potential neurology disease targets, as well as tiered royalties on potential net sales.
• Announced in December that Sangamo is scheduled to regain full rights to giroctocogene fitelparvovec, an investigational gene therapy product candidate for the treatment of adults with moderately severe to severe hemophilia A that it has co-developed with, and licensed to, Pfizer, Inc. (Pfizer), following a decision by Pfizer to terminate the global collaboration and license agreement between the parties. Sangamo continues to explore how to maximize the value of the SB-525 program, including a search for a potential new collaboration partner.

Core Neurology Pipeline

Chronic Neuropathic Pain – ST-503

• IND application cleared by the FDA for ST-503, an investigational epigenetic regulator for the treatment of intractable pain due to iSFN, a type of chronic neuropathic pain.
• Preparing for a Phase 1/2 study of ST-503 to assess the safety, tolerability and preliminary efficacy of a one-time dose administered intrathecally to patients with intractable pain due to iSFN.
• Expect to commence patient enrollment and dosing in mid-2025, with preliminary proof of efficacy data anticipated in Q4 2026.

Prion Disease

• Clinical Trial Authorisation (CTA) enabling activities continue to advance for Sangamo’s product candidate to treat prion disease, leveraging STAC-BBB.
• Published a manuscript in bioRxiv titled, “Zinc Finger Repressors mediate widespread prion depletion from the nonhuman primate brain and profoundly extend survival in prion disease mice” demonstrating nonclinical proof of concept for this approach. A single intravenous infusion of Sangamo’s ZFR significantly reduced expression of prion mRNA and protein in the mouse brain, extended mouse survival and improved an array of molecular, histological, biomarker and behavior readouts – even when administered post-symptomatically to mice with prion disease. In addition, a single intravenous administration of the prion ZFR, delivered via STAC-BBB to nonhuman primates, resulted in potent and widespread reduction of prion expression in transduced neurons throughout the brain.
• A CTA submission is expected in Q1 2026, with preliminary clinical data anticipated in Q4 2026.

Novel Adeno-Associated Virus (AAV) Capsid Delivery Technology

• Actively engaged in advanced contract negotiations with a potential collaborator for a third STAC-BBB license agreement for use in delivering intravenously administered genomic medicines for certain specified neurological diseases.

Clinical – Fabry Disease

• Presented updated Phase 1/2 STAAR study data at the 21st Annual WORLDSymposium in San Diego, CA in February 2025 showing sustained benefit, improvements in kidney function and a favorable safety profile, following a single administration of isaralgagene civaparvovec in 33 adults with Fabry disease.
• Elevated expression of alpha-galactosidase A (α-Gal A) activity maintained for nearly four years for the longest treated patient as of the September 12, 2024 data cutoff date.
• Positive mean estimated glomerular filtration rate (eGFR) slope of 3.061 mL/min/1.73m2/year (95% confidence interval: 0.863, 5.258) was observed in the 23 patients who had reached at least one-year follow-up, indicating notable improvements in renal function.
• All 18 patients who began the study on enzyme replacement therapy (ERT) have been withdrawn from, and remain off, ERT as of March 17, 2025.
• Significant improvements continued to be observed in the short form-36 (SF-36) quality of life (QoL) scores reported, with a mean change in General Health score of 10.6. Significant improvements in physical component, bodily pain, physical, vitality, social function, and emotional SF-36 scores were also observed.
• Enrollment and dosing are complete in the Phase 1/2 STAAR study.
• The FDA has provided a clear regulatory pathway to Accelerated Approval for isaralgagene civaparvovec, agreeing that data from the ongoing Phase 1/2 STAAR study can serve as the primary basis for approval under the Accelerated Approval Program, using eGFR slope at 52 weeks across all patients as an intermediate clinical endpoint.
• The 52-week eGFR slope data from all enrolled patients in the Phase 1/2 STAAR study will be available in the first half of 2025. A potential Biologics License Application (BLA) submission is anticipated in the second half of 2025.
• Sangamo is advancing BLA preparation activities for isaralgagene civaparvovec, while continuing to engage in business development negotiations for a potential Fabry commercialization agreement.

Fourth Quarter and Full Year 2024 Financial Results

Consolidated net loss for the fourth quarter ended December 31, 2024 was $23.4 million, or $0.11 per share, compared to consolidated net loss of $60.3 million, or $0.34 per share, for the same period in 2023. For the year ended December 31, 2024, consolidated net loss was $97.9 million, or $0.49 per share, compared to consolidated net loss of $257.8 million, or $1.48 per share, for the year ended December 31, 2023.

Revenues

Revenues for the fourth quarter ended December 31, 2024 were $7.6 million, compared to $2.0 million for the same period in 2023.

The increase of $5.5 million in revenues was primarily attributed to $6.5 million and $0.8 million in revenues relating to our license agreements with Astellas Gene Therapies, Inc., or Astellas, and Genentech, Inc., respectively, partially offset by revenue decreases in other collaborations.

Revenues were $57.8 million in 2024, compared to $176.2 million in 2023.

The decrease of $118.4 million in revenues in 2024 compared to 2023 was primarily attributed to decreases of $134.8 million and $12.2 million in revenues relating to our collaboration agreements with Biogen and Novartis, respectively, due to the termination of these collaboration agreements in June 2023, a decrease of $20.5 million in revenue relating to our collaboration agreement with Kite, which expired pursuant to its terms in April 2024, a decrease of $4.7 million in revenue relating to our license agreements with Sigma and Ligand, and a decrease of $2.7 million in revenue relating to our other license agreements. These decreases were partially offset by $50.0 million in revenue relating to our license agreement with Genentech and $6.5 million in revenue relating to our license agreement with Astellas.

Total operating expenses on a GAAP basis for the fourth quarter ended December 31, 2024 were $33.5 million compared to $64.1 million for the same period in 2023. Non-GAAP operating expenses, which exclude impairment charges, depreciation and amortization and stock-based compensation expense as shown in the reconciliation table above, for the fourth quarter ended December 31, 2024 were $29.0 million, compared to $55.9 million for the same period in 2023.

Total operating expenses on a GAAP basis in 2024 were $161.8 million compared to $450.2 million in 2023. Non-GAAP operating expenses, which exclude impairment charges, depreciation and amortization and stock-based compensation expense as shown in the reconciliation table above, were $138.8 million in 2024 compared to $252.7 million in 2023.

The decrease in total operating expenses on a GAAP basis was primarily driven by cost reductions resulting from the strategic realignment of the business, which included a lower headcount due to the restructuring of operations and corresponding reductions in workforce announced during 2023. Additionally, the decrease reflects intentional reprioritization of research and development investments, with a focused shift toward advancing the neurology pipeline. Other contributing factors included lower impairment charges recorded in the current year, lower preclinical and clinical expenses due to program deferrals, a decrease in restructuring charges related to the 2023 restructuring of operations, a decrease in depreciation due to reduced carrying values as a result of impairment charges recorded in 2023, and a decrease in external professional services, facilities, and infrastructure-related costs.

Cash and Cash Equivalents

Cash and cash equivalents as of December 31, 2024 were $41.9 million, compared to cash, cash equivalents and marketable securities of $81.0 million as of December 31, 2023. Based on our current operating plan, we believe that our cash and cash equivalents as of December 31, 2024, together with $10.1 million generated to date through our at-the-market offering program in 2025 and the $5.0 million payment expected from Pfizer by the end of March, will be sufficient to fund our planned operations into the middle of the second quarter of 2025.

Financial Guidance for 2025

• 2025 operating expenses on a non-GAAP basis are expected to be roughly in line with 2024, reflecting our intention to operate a lean neurology-focused business and to continue advancing isaralgagene civaparvovec towards a potential BLA submission, while engaging in business development negotiations for a potential Fabry commercialization agreement.
• On a GAAP basis, we expect total operating expenses in the range of approximately $135 million to $155 million in 2025, which includes estimated non-cash stock-based compensation expense, and depreciation and amortization.
• We expect non-GAAP total operating expenses, excluding estimated non-cash stock-based compensation expense of approximately $7 million, and estimated depreciation and amortization of approximately $3 million, in the range of approximately $125 million to $145 million in 2025, consistent with the prior year.

Non-GAAP Financial Measures

To supplement our financial results and guidance presented in accordance with GAAP, we present non-GAAP operating expenses, which excludes depreciation and amortization, stock-based compensation expense and impairment of goodwill, indefinite-lived intangible assets and long-lived assets from GAAP operating expenses. We believe that this non-GAAP financial measure, when considered together with our financial information prepared in accordance with GAAP, can enhance investors’ and analysts’ ability to meaningfully compare our results from period to period and to our forward-looking guidance, and to identify operating trends in our business. We have excluded depreciation and amortization, and stock-based compensation expense because they are non-cash expenses that may vary significantly from period to period as a result of changes not directly or immediately related to the operational performance for the periods presented, and we have excluded impairment of goodwill, indefinite-lived intangible assets and long-lived assets to facilitate a more meaningful evaluation of our current operating performance and comparisons to our operating performance in other periods. This non-GAAP financial measure is in addition to, not a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. We encourage investors to carefully consider our results under GAAP, as well as our supplemental non-GAAP financial information, to more fully understand our business.
