RICHMOND, Calif., May 12, 2025--(BUSINESS WIRE)--Sangamo Therapeutics, Inc. (Nasdaq: SGMO), a genomic medicine company, today reported recent business highlights and first quarter 2025 financial results.
"This quarter we continued to advance our promising neurology genomic medicine pipeline and are pleased to have signed our third STAC-BBB license agreement, reinforcing that Sangamo is a collaborator of choice for neurotropic capsids," said Sandy Macrae, Chief Executive Officer of Sangamo Therapeutics. "We achieved significant clinical and regulatory derisking milestones in our Fabry disease program and raised additional capital through business development and other means, to provide additional runway to secure a potential Fabry partner. With our neuropathic pain program ready to enter the clinic, we look forward to dosing the first patients with our epigenetic regulation technology, which we hope will usher in a new era in chronic pain treatment."
Recent Business Highlights
Corporate Updates
Announced in April a capsid license agreement with Eli Lilly and Company (Lilly) to deliver genomic medicines for diseases of the CNS. Agreement grants Lilly a worldwide exclusive license to Sangamo’s novel proprietary neurotropic adeno-associated virus (AAV) capsid, STAC-BBB, for up to five potential disease targets. Received an $18 million upfront license fee from Lilly and eligible to earn up to $1.4 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 pricing of a $23 million underwritten registered direct offering of equity securities, which is expected to close on May 14, 2025, subject to customary closing conditions.
Fabry Disease
All dosed patients in the Phase 1/2 STAAR study evaluating isaralgagene civaparvovec, an investigational gene therapy for the treatment of Fabry disease, have now completed at least 52-weeks of follow-up, a key milestone required by the FDA for an Accelerated Approval regulatory pathway.
Preliminary analysis of clinical data collected as of the April 2025, 52-week milestone, date across all 32 dosed patients indicates that the mean estimated glomerular filtration rate (eGFR) slope continued to remain positive since the last clinical update, which had a data cutoff date of September 12, 2024, presented at the WORLDSymposium in February 2025.
The product candidate continues to be well tolerated, and a pivotal data readout is expected by the end of the second quarter of 2025.
In April 2025, held a productive Type B meeting with the FDA, providing Sangamo with a clear CMC pathway to a planned BLA submission as early as the first quarter of 2026, including clarity on plans for process validation, path to commercial specifications and the commercial launch manufacturing site.
This BLA submission timeline would facilitate a potential approval and commercial launch as early as the second half of 2026.
Sangamo is advancing BLA preparation activities for isaralgagene civaparvovec, while continuing to engage in business development negotiations for a potential Fabry commercialization agreement.
Core Neurology Pipeline
Chronic Neuropathic Pain – ST-503
Advanced preparations for the Phase 1/2 study of ST-503, an investigational epigenetic regulator for the treatment of intractable pain due to iSFN, a type of chronic neuropathic pain.
Expect to commence patient enrollment and dosing in mid-2025, with preliminary proof of efficacy data anticipated in Q4 2026.
Prion Disease – ST-506
Clinical Trial Authorisation (CTA) enabling activities continue to advance for ST-506, an investigational epigenetic regulator for the treatment of prion disease, leveraging STAC-BBB.
A CTA submission is expected in Q1 2026, with preliminary clinical data anticipated in Q4 2026.
Novel AAV Capsid Delivery Technology

First Quarter 2025 Financial Results
Consolidated net loss for the first quarter ended March 31, 2025 was $30.6 million, or $0.14 per share, compared to a net loss of $49.1 million, or $0.27 per share, for the same period in 2024.
Revenues
Revenues for the first quarter ended March 31, 2025 were $6.4 million, compared to $0.5 million for the same period in 2024.
The increase in revenues was primarily attributed to $5.0 million in revenue relating to our collaboration agreement with Pfizer upon transfer of a specified sublicense and an increase of $1.0 million in revenue relating to our license agreement with Sigma-Aldrich Corporation.

Total operating expenses on a GAAP basis for the first quarter ended March 31, 2025 were $36.1 million compared to $52.0 million for the same period in 2024. Non-GAAP operating expenses, which exclude depreciation and amortization, stock-based compensation expense, and impairment charges for the first quarter ended March 31, 2025 were $32.5 million, compared to $43.6 million for the same period in 2024.
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. Additionally, the decrease reflects reprioritization of research and development investments, with a shift toward neurology programs. Other contributing factors included lower preclinical and clinical expenses due to program deferrals, lower impairment charges recorded in the current year, a decrease in restructuring charges related to the 2023 restructuring of operations, and a decrease in external professional services, facilities and infrastructure costs.
Cash and Cash Equivalents
Cash and cash equivalents as of March 31, 2025 were $25.2 million, compared to cash and cash equivalents of $41.9 million as of December 31, 2024. Based on our current operating plan, we believe that our cash and cash equivalents as of March 31, 2025, together with the $18.0 million upfront license fee received from Lilly in April 2025, the anticipated net proceeds from the underwritten offering announced today, and our at-the-market offering program since March 31, 2025, will be sufficient to fund our planned operations into late in the third quarter of 2025.
Financial Guidance for 2025 Reiterated (initial guidance provided on March 17, 2025)
On a GAAP basis, we continue to 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 continue to 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 2024. This reflects 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.
In addition, we expect to implement additional cost saving measures over the near term to further reduce our operating expenses and maximize the efficiency of the go-ahead neurology-focused genomic medicine company.
