(Nasdaq: ALLO), a clinical-stage biotechnology company pioneering the development of allogeneic CAR T (AlloCAR T) products for cancer and autoimmune disease, today announced preliminary safety, efficacy and translational data from the ongoing Phase 1 RESOLUTION study evaluating ALLO-329, an investigational, next-generation, off-the-shelf allogeneic CAR T product designed specifically for autoimmune disease. The data are being presented today at the American College of Rheumatology (ACR) Convergence in Orlando, Florida.<\/p>\n<p>ALLO-329 incorporates Allogene\u2019s proprietary Dagger<sup>\u00ae<\/sup> technology, designed to enhance allogeneic CAR T activity while potentially reducing or eliminating conventional cytotoxic lymphodepletion (LD). The RESOLUTION trial is evaluating escalating doses of ALLO-329 with three LD conditioning regimens: no LD, cyclophosphamide (Cy) alone, or fludarabine plus cyclophosphamide (Flu\/Cy). As of the September 21, 2026 data cutoff, 18 patients with systemic sclerosis (SSc\/scleroderma), idiopathic inflammatory myopathies (IIM\/myositis), or systemic lupus erythematosus (SLE\/lupus) had received a single dose of ALLO-329 and completed the 28-day dose-limiting toxicity assessment period.<\/p>\n<p>\u201cThese initial results provide a solid foundation for ALLO-329, our first dual targeting CAR T product to emerge from our Dagger pipeline,\u201d said Zachary Roberts, M.D., Ph.D., President and Chief Executive Officer of Allogene Therapeutics. \u201cWe are seeing meaningful and durable clinical improvement in patients with scleroderma across very different conditioning approaches, including without lymphodepletion, and even at the lowest cell doses studied. Our goal has always been to develop ALLO-329 with safety as the top priority while also delivering meaningful clinical benefit at a reduced treatment burden for patients with chronic autoimmune disease.\u201d<\/p>\n<p>\n        <strong>Favorable Early Safety Profile Across Lymphodepletion Approaches<\/strong><br \/>\n        <br \/>ALLO-329 demonstrated a favorable early safety profile across all 18 patients. There were no dose-limiting toxicities (DLTs), immune effector cell-associated hemophagocytic syndrome (IEC-HS), immune effector cell-associated neurotoxicity syndrome (ICANS), graft-versus-host disease (GvHD) or Grade \u22653 CRS events in any patient. Four patients (22%) experienced CRS (three with Grade 1, and one with Grade 2). All patients experienced at least one TEAE with 83% being Grade 1 or Grade 2. No patients in the no-LD cohorts experienced any TEAEs greater than Grade 2.<\/p>\n<p>\n        <strong>Summary of Adverse Events <\/strong>\n      <\/p>\n<table style=\"border-top: solid black

focuses on 10 patients with skin-predominant SSc, a serious autoimmune disease associated with substantial morbidity and mortality for which current therapies are largely chronic, immunosuppressive and organ-directed. No therapy has been shown to reliably halt or reverse disease progression. Four patients with IIM, two patients with SLE, and two patients with non-skin-predominant SSc were also treated as of the data cutoff and are expected to be the focus of future presentations.<\/p>\n<p>Preliminary efficacy was observed in these 10 patients with early and durable improvements in modified Rodnan skin score (mRSS), a validated measure of skin involvement. Improvements were observed as early as Day 14 across all three ALLO-329 dose levels and LD approaches evaluated as of the data cutoff, including without LD. Eight of 10 patients achieved and maintained a five-point or greater improvement in mRSS, with several patients experiencing rapid and substantially greater reductions of 10 points or more. Notably, four patients achieved total mRSS scores below 10, reflecting a low level of skin involvement, despite having progressive disease at baseline. Nine of 10 patients remained off background immunosuppressive therapy as of the data cutoff, with the longest treatment-free interval ongoing beyond eight months.<\/p>\n<p>Individual patient assessments showed improvements beyond skin score, including in validated measures of patient-reported disease impact and physical function. In one patient treated with 40 million cells plus Cy, improvement in mRSS was accompanied by improvement in Patient Global Assessment, resolution of tendon friction rubs, and improvement in the Health Assessment Questionnaire-Disability Index (HAQ-DI), a validated measure of functional disability. In a second patient treated with 40 million cells and no-LD, digital ulcers and tendon friction rubs resolved, and HAQ-DI improved from 1.63 to 0, a change that substantially exceeds published estimates of the minimal clinically important difference for HAQ-DI in systemic sclerosis. These multidimensional improvements are notable in a disease where approved therapies have generally demonstrated benefit in specific organ-based endpoints rather than across skin, function and patient-reported outcomes simultaneously.<\/p>\n<p>\u201cSystemic sclerosis remains a disease with substantial unmet need, particularly for patients who continue to progress despite immunosuppressive therapy,\u201d said Vivek Nagaraja, M.D., FACR, Mayo Clinic Arizona and lead author of the ACR poster presentation. \u201cIn this early cohort, we observed clinically meaningful reductions in skin involvement across the treatment approaches evaluated, including in patients who stopped their immunosuppressant regimens and received ALLO-329 without lymphodepleting chemotherapy. The consistency of the initial clinical improvement across conditioning regimens is encouraging, particularly given that these observations are occurring early in dose escalation. Continued follow-up will provide further insight into the durability of these encouraging early skin responses.\u201d<\/p>\n<p>\n        <strong>Study Design Provides Insight into the Role of Lymphodepletion<\/strong><br \/>\n        <br \/>RESOLUTION\u2019s novel parallel dose-escalation design enables systematic evaluation of conditioning intensity, helping distinguish ALLO-329\u2013mediated effects from those of chemotherapy-based conditioning and define the minimum lymphodepletion, if any, needed for meaningful clinical activity.<\/p>\n<p>B-cell suppression occurred across all LD approaches, with the depth of B-cell and total lymphocyte suppression increasing with lymphodepletion intensity. Pre-treatment B-cell and lymphocyte counts recovered most rapidly in patients with no LD. Importantly, durable clinical improvement occurred without complete peripheral B-cell depletion, raising the possibility that peripheral B-cell aplasia may not be required to achieve an immune reset.<\/p>\n<p>\u201cRESOLUTION was designed not only to determine whether ALLO-329 can treat autoimmune disease, but to understand which components of the treatment regimen are contributing to clinical activity,\u201d said Eric Zollars, M.D., Ph.D., Vice President, Clinical Development in Autoimmune Disease at Allogene. \u201cClinical improvement across the three lymphodepletion regimens at these early doses, as well as clear differences in depth and duration of lymphocyte count suppression, should help us to identify a regimen that optimizes benefit and risk while reducing chemotherapy and lengthy intervals of immune suppression.\u201d<\/p>\n<p>\n        <strong>RESOLUTION Study Next Steps<\/strong><br \/>\n        <br \/>RESOLUTION (NCT07085104) is a first-in-human Phase 1 study evaluating escalating doses of ALLO-329 with and without lymphodepletion in adults with active SSc, IIM and SLE. The dose-escalation portion includes five planned ALLO-329 dose levels (20 million, 40 million, 80 million, 160 million and 320 million cells). Enrollment began in November 2025 and dose escalation continues to inform selection of a Phase 2 regimen.

In April 2025, the U.S. Food and Drug Administration granted three Fast Track Designations (FTD) to ALLO-329 for the treatment of adult patients with lupus, myositis, and scleroderma. ALLO-329 utilizes CRISPR-based site-specific integration for dual CAR expression. This approach targets both CD19+ B cells and CD70+ T cells, which play a role in autoimmune disease pathogenesis. Additionally, ALLO-329 incorporates Allogene&#8217;s clinically validated Dagger<sup>\u00ae<\/sup> technology, designed to reduce or eliminate the need for lymphodepletion, a pre-treatment regimen that may be a significant barrier to CAR T cell therapy adoption in autoimmune indications.<\/p>\n<p>\n        <strong>About Allogene Therapeutics<\/strong><br \/>\n        <br \/>Allogene Therapeutics, with headquarters in\u00a0South San Francisco, is a clinical-stage\u00a0biotechnology company pioneering the development of allogeneic chimeric antigen receptor T\u00a0cell (AlloCAR T) products for cancer and autoimmune disease.
