BRISBANE, Calif.--(BUSINESS WIRE)-- Sangamo Therapeutics, Inc. (Nasdaq: SGMO), a genomic medicines company, today announced recent business highlights, including a strategic pipeline prioritization and restructuring, and reported certain preliminary first quarter 2023 financial results.

“This quarter, Sangamo continued to advance its clinical and pre-clinical pipeline. Our Phase 1/2 Fabry study continues to enroll and dose patients, alongside preparations for a potential Phase 3 trial expected to commence by the end of 2023. We successfully dosed the third patient with TX200, our CAR-Treg therapy in kidney transplantation, and received positive regulatory feedback from the first two European authorities required to accelerate the dose escalation. We are also excited to unveil Nav 1.7 as the prioritized target in our wholly owned neurology epigenetic regulation pipeline,” said Sandy Macrae, Chief Executive Officer of Sangamo. “Today’s environment necessitates careful choices when deciding how many programs to take forward at once. We are therefore announcing a sharpened strategic focus, prioritizing our investments in our most promising programs. This has led to difficult, but necessary, decisions to step away from certain pre-clinical assets, shrink parts of our infrastructure and redeploy investments towards realizing the full potential of what we believe are our most valuable programs.”

The restructuring announced today is the result of a strategic decision to increase focus on three key areas: Nav 1.7 and Prion as cornerstones to the neurology epigenetic regulation portfolio; Fabry Phase 3 readiness; and the TX200 CAR-Treg clinical study, alongside a broader rightsizing of resources and investments across the company. Additionally, Sangamo expects to significantly reduce its internal manufacturing and allogeneic research footprints in California. As a result of this restructuring, Sangamo is reducing its US workforce by approximately 27%, or approximately 120 roles. These actions are in addition to the previously announced portfolio prioritization which resulted in the decision to seek a partner for our sickle cell disease program. In addition, R. Andrew Ramelmeier, Ph.D., Executive Vice President, Technical Operations will be leaving the company on July 10, 2023. Phillip Ramsey, currently serving as Vice President, Technical Development, has been appointed as Head of Technical Operations effective May 29, 2023.

The restructuring plus other planned cost reduction initiatives are expected to result in annualized savings of approximately $31 million. Sangamo believes its available cash, cash equivalents and marketable securities as of March 31, 2023, in combination with the other expected cost reductions, will be sufficient to fund its planned operations for at least the next 12 months. Sangamo expects to incur approximately $5 million - $7 million in one-time restructuring costs in the second and third quarters of 2023. Sangamo is assessing ways to further reduce annual operating expenses, consistent with the prioritized objectives and progress of the company.

“I am grateful to all our employees for their commitment to Sangamo and dedication to patients, and have special gratitude to those who are leaving for all they have done to advance our mission. Additionally, I would like to personally thank Andy for the passion, dedication and leadership he has brought to Sangamo. He leaves a great legacy of technical excellence and I wish him well in the future.”

Preliminary First Quarter 2023 Financial Results

Sangamo is in the process of completing its customary quarter-end close and review procedures, including the evaluation of non-cash charges related to impairment of long-lived assets, as of and for the quarter ended March 31, 2023, and the final results for this period could materially differ from the preliminary expected results disclosed in this press release. Sangamo’s full first quarter 2023 financial results will be reflected in a Quarterly Report on Form 10-Q which is expected to be filed no later than May 10, 2023. The financial performance measures presented in this press release for the first quarter of 2023 are forward-looking statements, preliminary estimates and unaudited, based on management’s initial review of the information presented, and are thus inherently uncertain and subject to change as Sangamo completes its end-of-period reporting process and related activities for the first quarter of 2023. During the course of the review of Sangamo’s condensed consolidated financial statements and related notes as of and for the quarter ended March 31, 2023, Sangamo’s independent registered public accountants may identify items that could cause final reported results to be materially different from the preliminary estimates presented herein. Additional information and disclosures would be required for a more complete understanding of Sangamo’s financial position and results of operations as of and for the quarter ended March 31, 2023. Accordingly, undue reliance should not be placed on this preliminary information.

Revenues

Revenues for the first quarter ended March 31, 2023, are estimated to be approximately $158.0 million, compared to $28.2 million for the same period in 2022.

The estimated increase of $129.8 million in revenues is primarily attributable to an increase of $121.1 million in revenue relating to our collaboration agreement with Biogen, mainly due to the impact of termination related contract modification, and an increase of $6.0 million in revenue relating to our collaboration agreement with Kite, mainly due to a reduction in the estimated project costs, which resulted in an adjustment to the measure of proportional cumulative performance.

Operating Expenses

Total operating expenses on a GAAP basis for the first quarter ended March 31, 2023, are estimated to be in the range of $120 million to $140 million, compared to $73.5 million for the same period in 2022.

The total estimated operating expenses on a GAAP basis for the quarter included certain non-cash charges such as impairment of goodwill of $38.1 million, and impairment of long-lived assets of up to $20 million. These estimated charges are a result of the termination of our collaboration agreements with Biogen and Novartis, a sustained decline in our stock price and related market capitalization and a general decline in equity values in the biotechnology industry.

Cash, Cash Equivalents and Marketable Securities

Cash, cash equivalents and marketable securities as of March 31, 2023 were $241.0 million, compared to $307.5 million as of December 31, 2022.

Sangamo believes its available cash, cash equivalents and marketable securities as of March 31, 2023, in combination with the other expected cost reductions, will be sufficient to fund its planned operations for at least the next 12 months.

Financial Guidance for 2023 Updated

In line with the business announcements outlined, we are revising our full-year operating expense guidance as follows:

• GAAP operating expenses, including goodwill and long-lived assets impairment charges and stock-based compensation expense, are estimated to be in the range of approximately $315 million to $335 million (updated on April 26, 2023). The previous GAAP operating expenses guidance provided on February 22, 2023 was in the range of approximately $310 million to $330 million.
• Non-GAAP operating expenses are estimated to be in the range of approximately $240 million to $260 million (updated on April 26, 2023). Estimated non-GAAP operating expenses exclude impairment of goodwill of $38 million, impairment of long-lived assets of up to $20 million and stock-based compensation expense of $35 million. The previous non-GAAP operating expenses guidance provided on February 22, 2023 was in the range of approximately $275 million to $295 million.

These forward-looking statements include, without limitation, statements relating to: our preliminary estimated operating results for the quarter ended March 31, 2023, the therapeutic and commercial potential of our product candidates, the anticipated plans and timelines of Sangamo and our collaborators for screening, enrolling and dosing patients in and conducting our ongoing and potential future clinical trials and presenting clinical data from our clinical trials, including expectations regarding the conclusion of dosing in our Phase 1/2 STAAR study, preparations and plans for patient dosing in the STEADFAST study and the potential for acceleration of the study timeline, the anticipated advancement of our product candidates to late-stage development, including potential future Phase 3 trials of isaralgagene civaparvovec and the timing thereof, the availability and presentation of data from the Phase 3 AFFINE trial, and plans for a BLA and MAA submission for giroctocogene fitelparvovec, expectations regarding advancement of our preclinical neurology programs, including announcement of data from, and anticipated IND submissions related to, such programs, the potential for a partner for our sickle cell disease program; expectations concerning our strategic prioritization and restructuring, including plans to reduce our manufacturing and allogenic research footprints and the expected charges and cost savings associated with such restructuring, future cost reductions, our expected cash runway, our 2023 financial guidance related to GAAP and non-GAAP total operating expenses and stock-based compensation, our plans to participate in industry and investor conferences, and other statements that are not historical fact. These statements are not guarantees of future performance and are subject to certain risks and uncertainties that are difficult to predict. Factors that could cause actual results to differ include, but are not limited to, risks and uncertainties related to impediments to adjustments to Sangamo’s preliminary measures of financial performance resulting from, among other things, the completion of Sangamo’s financial close procedures; Sangamo’s ability to execute its strategic prioritization and restructuring as currently contemplated; the actual charges associated with the restructuring being higher than anticipated or changes to the assumptions on which the estimated charges associated with the restructuring are based; Sangamo’s ability to achieve projected cost savings in connection with the restructuring and to further reduce operating expenses; unintended consequences from the restructuring that impact Sangamo’s business; the effects of macroeconomic factors or financial challenges, including as a result of the ongoing conflict between Russia and Ukraine, the COVID-19 pandemic and current or potential future bank failures, on the global business environment, healthcare systems and business and operations of Sangamo and our collaborators, including the initiation and operation of clinical trials; the research and development process, including the enrollment, operation and results of clinical trials and the presentation of clinical data; the impacts of clinical trial delays, pauses and holds on clinical trial timelines and commercialization of product candidates; the uncertain timing and unpredictable nature of clinical trial results, including the risk that therapeutic effects in the Phase 3 AFFINE trial will not be durable in patients as well as the risk that the therapeutic effects observed in the latest preliminary clinical data from the Phase 1/2 STAAR study, including data from kidney biopsies, and the Phase 1/2 PRECIZN-1 study will not be durable in patients and that final clinical trial data from the study will not validate the safety and efficacy of isaralgagene civaparvovec, and that the patients withdrawn from ERT will remain off ERT; the unpredictable regulatory approval process for product candidates across multiple regulatory authorities; reliance on results of early clinical trials, which results are not necessarily predictive of future clinical trial results, including the results of any Phase 3 trial of our product candidates; our limited experience manufacturing biopharmaceutical products, including the risks that we may be unable to maintain compliant manufacturing facilities, build additional facilities and manufacture our product candidates as intended; the potential for technological developments that obviate technologies used by Sangamo; our lack of capital resources to fully develop, obtain regulatory approval for and commercialize our product candidates, and our related need for substantial additional funding to execute our operating plan and to continue to operate as a going concern; our reliance on collaborators and our potential inability to secure additional collaborations, including for our sickle cell disease program; and our ability to achieve expected future financial performance.

There can be no assurance that we and our collaborators will be able to develop commercially viable products. Actual results may differ materially from those projected in these forward-looking statements due to the risks and uncertainties described above and other risks and uncertainties that exist in the operations and business environments of Sangamo and our collaborators. These risks and uncertainties are described more fully in our Securities and Exchange Commission, or SEC, filings and reports, including in our Annual Report on Form 10-K for the year ended December 31, 2022, as supplemented by our Quarterly Report on Form 10-Q for the quarter ended March 31, 2023 to be filed with the SEC, and future filings and reports that Sangamo makes from time to time with the SEC. Forward-looking statements contained in this announcement are made as of this date, and we undertake no duty to update such information except as required under applicable law.

Non-GAAP Financial Measures

To supplement our financial guidance presented in accordance with GAAP, we present non-GAAP total operating expenses financial guidance, which exclude stock-based compensation expense and impairment of goodwill and long-lived assets from GAAP total operating expenses. We believe that these non-GAAP financial measures, 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 stock-based compensation expense because it is a non-cash expense 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 and long-lived assets to facilitate a more meaningful evaluation of our current operating performance and comparisons to our operating performance in other periods. These non-GAAP financial measures are 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.
