Sangamo Therapeutics Reports Recent Business and Clinical Highlights and Third Quarter 2021 Financial Results
Sangamo Therapeutics (SGMO) reported its Q3 2021 financial results, revealing a net loss of $47.7 million or $0.33 per share, a significant increase from a loss of $1.6 million in Q3 2020. Revenue dropped to $28.6 million, down from $57.8 million, mainly due to reduced collaboration revenue with Pfizer. Key clinical updates include positive data from its Fabry disease and hemophilia A programs, with plans for a Phase 3 trial for Fabry disease. Additionally, preliminary results for its sickle cell disease therapy will be shared at the ASH meeting in December.
- Fabry disease data shows patients with above normal α-Gal A activity, leading to Phase 3 trial planning.
- Sickle cell program shows promising preliminary results with no transfusions required post-engraftment.
- Hemophilia A treatment demonstrates mean FVIII activity of 30.9% at 104 weeks with zero annualized bleeding rate.
- Q3 2021 revenue decreased by $29.2 million compared to Q3 2020.
- Net loss significant increase from $1.6 million in Q3 2020 to $47.7 million in Q3 2021.
- Clinical hold on the Phase 3 AFFINE trial for hemophilia A necessitated by protocol amendment.
Conference Call and Webcast Scheduled for
“We are delighted to share clinical data and business updates across several programs demonstrating that Sangamo has three important assets progressing toward late-stage development. Our gene therapy portfolio is advancing with accumulating safety and efficacy data in our Fabry and hemophilia A programs, and preliminary proof-of-concept data demonstrate the clinical potential of our zinc finger genome engineering technology in sickle cell disease. These data readouts show the progression of our first-generation genomic medicine pipeline and potentially pave the way for new treatments. Our next generation programs focus on genome regulation and allogeneic CAR-Treg cell therapy, where we have a robust preclinical pipeline in neurological and autoimmune diseases. We are energized by this momentum and look forward to continued execution of our corporate strategy,” said
Recent Clinical and Business Highlights
Fabry Disease – First four patients dosed exhibited above normal α-Gal A activity; Phase 3 planning initiated
-
Earlier today, we announced preliminary clinical data from the first four patients treated in our Phase 1/2 STAAR study evaluating isaralgagene civaparvovec, or ST-920, our wholly owned Fabry disease gene therapy product candidate. Data as of the
September 17, 2021 cutoff date from the four patients in the first two dose cohorts showed that isaralgagene civaparvovec was generally well tolerated. All four patients exhibited above normal alpha-galactosidase A (α-Gal A) activity, which was maintained for up to one year for the first patient treated and through 14 weeks for the most recently treated patient. Activity of 2-fold to 15-fold above mean normal was observed at last measurement as of the cutoff date. Withdrawal from enzyme replacement therapy (ERT) has taken place for one patient and is planned for the other patient on ERT, based on the stability of their α-Gal A activity following treatment. - The fifth patient in the STAAR study, who is the first patient in the third cohort (3e13vg/kg), was dosed after the cutoff date. The sixth patient is currently in screening also for the third dose cohort. We expect to provide updated data throughout 2022 and present these results at a medical meeting.
- Based on the STAAR study results to date, we have initiated planning for a Phase 3 Fabry disease clinical trial.
Sickle Cell Disease – Preliminary-proof-of-concept data will be presented at ASH as clinical program advances
-
Preliminary proof-of-concept results from the Phase 1/2 PRECIZN-1 study investigating
SAR445136 , formerly BIVV003, an investigational zinc finger nuclease gene edited cell therapy, in patients with severe sickle cell disease (SCD) will be presented at the 63rd Annual Meeting of theAmerican Society of Hematology (ASH ) onDecember 12, 2021 . Results as of theJune 25, 2021 cutoff date show that all four treated patients did not require blood transfusions post engraftment and had no adverse or serious adverse events related toSAR445136 through 65 weeks of follow-up for the longest treated patient. The four treated patients all experienced increases in total hemoglobin, fetal hemoglobin and percent F cells. -
We and Sanofi continue to advance the sickle cell disease program. We recently obtained manufacturing requirements guidance from FDA in preparation for further potential clinical studies. Separately, we and Sanofi made the business decision to cease development of the beta thalassemia indication in order to focus resources on the sickle cell disease program. ST-400 for beta thalassemia was developed with the support of a grant from the
California Institute for Regenerative Medicine (CIRM).
Hemophilia A – Four patients at highest dose experienced mean FVIII activity of
-
Updated follow-up results from the Phase 1/2 Alta study of giroctocogene fitelparvovec gene therapy in patients with severe hemophilia A will be presented at ASH on
December 12, 2021 . For the four patients in the highest dose 3e13vg/kg cohort who have reached 104 weeks of follow-up as of theMay 19, 2021 cutoff date, mean Factor VIII (FVIII) activity was30.9% at week 104 as measured by chromogenic assay. In this cohort, the annualized bleeding rate was zero for the first year after treatment and 0.9 throughout total duration of follow-up. Giroctocogene fitelparvovec was generally well tolerated. -
We and Pfizer also announced that some of the patients treated in the Phase 3 AFFINE trial of giroctocogene fitelparvovec experienced FVIII activity greater than
150% following treatment. None of these patients have experienced thrombotic events and some have been treated with direct oral anticoagulants to reduce thrombotic risk. Pfizer voluntarily paused screening and dosing of additional patients in the trial to implement a protocol amendment intending to provide guidance regarding the management of patients with FVIII levels that exceed150% . OnNovember 3, 2021 , Pfizer was informed that the FDA has put this trial on clinical hold. The next step is to share the proposed protocol amendment with health authorities and respond to the clinical hold, after which the Companies will be able to provide updated timing for the trial.
Renal Transplant – First patient enrolled, expect two patients to be dosed by mid-2022
- The first patient has been enrolled in our Phase 1/2 STEADFAST study evaluating TX200, our wholly owned autologous HLA-A2 CAR Treg cell therapy product candidate treating patients receiving an HLA-A2 mismatched kidney from a living donor. We expect the first two patients in this study to be dosed by the middle of 2022 following kidney transplantation. We continue to open study sites and screen patients.
Research, Manufacturing, and Corporate Updates
- Biogen announced type 1 myotonic dystrophy (DM1) as the previously undisclosed neuromuscular preclinical target in our collaboration.
-
We recently completed and brought online our in-house cell therapy manufacturing facility in our
Brisbane, California headquarters and remain on track to complete our in-house cell therapy manufacturing facility in Valbonne,France by year-end. -
We appointed
D. Mark McClung as Chief Operating Officer, an important organizational step to support the multiple advancing wholly owned and partnered programs.

Forward-Looking Statements
This press release contains forward-looking statements regarding our current expectations. These forward-looking statements include, without limitation, statements relating to 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, the anticipated advancement of our product candidates to late-stage development including potential future Phase 3 trials, anticipated implementation of a protocol amendment for the Phase 3 AFFINE clinical trial of giroctocogene fitelparvovec and the resumption of the dosing of additional patients in the trial; our revised 2021 financial guidance related to GAAP and non-GAAP total operating expenses and stock-based compensation; our continued execution of our corporate strategy; the anticipated completion of our in-house cell therapy manufacturing facility in Valbonne,
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
Non-GAAP Financial Measure
To supplement our financial results and guidance presented in accordance with GAAP, we present non-GAAP total operating expenses, which exclude stock-based compensation expense from GAAP total 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 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. 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.
