Item 7.01 Regulation FD Disclosure.

On October 26, 2025, Fate Therapeutics, Inc. (the “Company”) issued a press release (i) announcing that 10 patients with treatment-refractory, moderate-to-severe systemic lupus erythematosus (“SLE”) were treated with a single dose of FT819, the Company’s off-the-shelf, CD19-targeted 1XX chimeric antigen receptor (“CAR”) T-cell product candidate as of a data cut-off date of September 25, 2025, and (ii) highlighting new and updated data (including, without limitation, translational data) as of the data cut-off date from the first 10 patients dosed with FT819 in a Phase 1 clinical trial for the treatment of moderate-to-severe SLE at the American College of Rheumatology (“ACR”) Convergence 2025 in Chicago. The press release also highlighted that the Company (i) has initiated independent dose-expansion cohorts in anti-neutrophilic cytoplasmic antibody-associated vasculitis (“AAV”), idiopathic inflammatory myositis (“IIM”), and systemic sclerosis (“SSc”), and (ii) is actively engaged under its Regenerative Medicine Advanced Therapy (“RMAT”) designation with the U.S. Food and Drug Administration (“FDA”) to align on a registrational study design with the goal of initiating a pivotal study in 2026. The press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K.

The Company posted links to the ACR Convergence 2025 abstracts in connection with its FT819 programs on its website.

The information in Item 7.01 of this Current Report on Form 8-K, including Exhibit 99.1 attached hereto, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, except as expressly set forth by specific reference in such filing.

Item 8.01 Other Events.

FT819 iPSC-derived CAR T-cell Program

On October 26, 2025, the Company (i) announced that 10 patients with treatment-refractory, moderate-to-severe SLE were treated with a single dose of FT819, the Company’s off-the-shelf, CD19-targeted CAR T-cell product candidate as of a data cut-off date of September 25, 2025, and (ii) highlighted new and updated data (including, without limitation, translational data) as of the data cut-off date at the ACR Convergence 2025 from its Phase 1 clinical trial of FT819 for the treatment of moderate-to-severe SLE, which data underscored the unique ability of FT819 to remodel the B-cell repertoire toward a more naïve and less pathogenic state without the need for intensive conditioning chemotherapy.

The study is designed to evaluate the safety, pharmacokinetics, and activity of a single dose of FT819 administered to patients with active refractory lupus with either (i) a less-intensive conditioning regimen (Regimen A; fludarabine (flu)-free conditioning consisting of either cyclophosphamide alone or bendamustine alone), or (ii) a conditioning-free regimen to patients on standard-of-care maintenance therapy (Regimen B). The Company announced key insights from the study with respect to 10 patients (8 on Regimen A, 2 on Regimen B) who have been treated with FT819 as of a data cut-off date of September 25, 2025.

The data showed that, in patients treated with less-intensive conditioning chemotherapy, rapid and sustained CD19+ B cell depletion was observed, positively correlating with dose escalation. Upon return of the B cell compartment, naïve B cell emergence beyond baseline levels was observed, suggestive of an immune reset and correlative to reduction in disease burden. Further, in patients treated without conditioning chemotherapy, a meaningful reduction in CD19+ B cells was also observed, alongside reduction in expanded B-cell clones and remodeling of the B-cell compartment that correlated with improvement in disease activity scores.

Forward Looking Statements
