(Nasdaq: ALLO), a clinical-stage biotechnology company pioneering the development of allogeneic CAR T (AlloCAR T™) products for cancer and autoimmune disease, today announced its 2024 Platform Vision that redefines the future of CAR T by leveraging the unique attributes of allogeneic CAR T products. “Until now, CAR T development has been defined by how autologous CAR Ts are made and used. As a management team with extensive experience in both autologous and allogeneic CAR Ts, and the only Company with the breadth of data to demonstrate comparability between the two, we are uniquely positioned to potentially redefine development and trial design of allogeneic CAR T products that allows us to do what no autologous CAR T has done before,” said David Chang, M.D., Ph.D., President, Chief Executive Officer and Co-Founder of Allogene. “We believe this entirely new approach to development creates an advantage for our investigational AlloCAR T™ products now and in the future while providing a clinical framework to generate far more competitive CAR T products and dramatically expand market opportunity.” The Foundation: Pivotal ALPHA3 1L Consolidation Trial in Large B Cell Lymphoma (LBCL)In a commanding pivot for the CD19 program, the Company will focus development of its investigational product cemacabtagene ansegedleucel, or cema-cel (previously known as ALLO-501A) as part of the first line (1L) treatment plan for newly diagnosed and treated LBCL patients who are likely to relapse and need further therapy. The groundbreaking design of the ALPHA3 1L consolidation trial builds upon the results demonstrated in the Phase 1 ALPHA2 trial and leverages an investigational cutting-edge diagnostic test developed by Foresight Diagnostics to identify patients who have minimal residual disease (MRD) at the completion of 1L chemoimmunotherapy for treatment with cema-cel. Although 1L R-CHOP is curative for many with LBCL, approximately 30% of patients who initially respond will relapsei. The standard of care after 1L treatment has been simply to “watch and wait” for the disease to relapse. ALPHA3 takes advantage of cema-cel as a one-time, off-the-shelf treatment that can be administered immediately upon discovery of MRD following six cycles of R-CHOP, positioning it to become the standard “7th cycle” of frontline treatment available to all eligible patients with MRD. ALPHA3 builds on the growing understanding that administration of CAR T therapies to patients with low disease burden improves both safety and efficacy outcomes. Cema-cel’s Phase 1 safety profile, with low rates of cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS), already permits its use in the outpatient setting in relapsed/refractory (r/r) patients and may further improve in patients with no radiological evidence of disease. Start-up activities for the ALPHA3 trial have been initiated. The study will randomize approximately 230 patients who are MRD positive at the end of 1L therapy to either consolidation with cema-cel or the current standard of care (observation). The design, with a primary endpoint of event free survival (EFS), will initially include two lymphodepletion arms (one with standard fludarabine and cyclophosphamide plus ALLO-647 and one without ALLO-647). The outcome of this pivotal trial could allow cema-cel to be embedded in the 1L setting to boost cure rates, potentially rendering later-line treatment obsolete, and making cema-cel available in community cancer centers where most earlier line patients seek care. As a result of this differentiated vision for cema-cel which competitively places its use ahead of other CAR T therapies, the Company will focus on quickly advancing this market-defining ALPHA3 trial and deprioritize the currently enrolling third line (3L) ALPHA2 and EXPAND trials. The Higher Bar: ALPHA2 Cema-Cel Trial in Chronic Lymphocytic Leukemia (CLL)There is a growing need for effective treatment in CLL post-Bruton tyrosine kinase inhibitors (BTKis) and B-cell lymphoma 2 inhibitor (BCL2i) therapies. While recent autologous CD19 CAR T data has been a positive step for patients with r/r CLL, these therapies are still not meeting the efficacy bar or expectations set in r/r LBCL. This is likely due in part to T cell dysfunction and high circulating tumor burden in CLL, making the isolation of functional T cells for autologous CAR T manufacturing difficult. There is strong scientific rationale to believe that an AlloCAR T™ product derived from healthy donor cells could raise the bar and potentially create a clinically meaningful advance for these late-stage patients, with a one-time dose and simpler administration and logistics. The new Phase 1 ALPHA2 cohort of 12 patients treated with the investigational product cema-cel provides the opportunity to set a higher bar where patients with CLL are not reliant on their own T cells’ fitness to benefit from the curative potential of CAR T. This study, driven by investigator enthusiasm, will leverage currently active ALPHA2 trial sites in the U.S. which should allow it to advance quickly. It is expected to begin enrolling in Q1 2024 with initial data projected by YE 2024. The Disruptor: ALLO-329 CD19 Dagger™ in Autoimmune Disease (AID)The Company is applying its deep understanding of CAR Ts to design a next-generation allogeneic CAR T with reduced or chemotherapy-free conditioning that the Company believes can sustain the scale of the AID market while meeting the unique requirements for these patients where they seek care. The risk tolerance of these patients is very different than those with cancer, in large part because of patient demographics, wide availability of effective therapies, and rheumatologists’ general lack of experience with chemotherapy, leukapheresis procedures and cell therapies. Incorporation of the Dagger technology into an off-the-shelf CD19 product for use in AID is designed to reduce or eliminate the need for standard chemotherapy while targeting CD19+ B-cells and CD70+ activated T-cells, both of which play a role in AID. Initiation of this Phase 1 trial with ALLO-329 is expected in early 2025. The Key: TRAVERSE ALLO-316 in Renal Cell Carcinoma (RCC)A fundamental discovery in early CAR T trials was the use of tocilizumab and steroids, the “safety key” needed to mitigate treatment-associated CRS without compromising CAR T function or efficacy. The Company believes it may have made the same cornerstone discovery in the TRAVERSE trial in renal cell carcinoma. During the careful advancement of the TRAVERSE trial with ALLO-316, the Company has observed remarkable allogeneic CAR T cell expansion and persistence driven by its unique CD70 CAR that allows elimination of alloreactive host lymphocytes. This biology has brought the potential for clinical efficacy not often seen in patients with r/r RCC but has also resulted in a hyperinflammatory response in some patients as CD70 CAR T cells expand and persist. Leveraging recent advances in the management of hyperinflammation following autologous CAR T administration, the Company has developed a diagnostic and treatment algorithm similar to what the management team previously helped develop for CRS and ICANS. Like tocilizumab and steroids, this algorithm may mitigate the treatment-associated hyperinflammatory response without compromising the CAR T function needed to eradicate solid tumors. The Company has recently implemented a protocol amendment to further maximize the benefit-risk of ALLO-316 in patients with CD70+ RCC. The next update from this trial is planned for a medical forum in Q2 2024 and will discuss the algorithm that is believed to be a critical advance for both the TRAVERSE trial as well as the industry at large. A more robust data update from the ongoing trial with the updated protocol is planned for later in 2024. The Source: Proprietary Cell Forge 1 Allogeneic CAR T Manufacturing FacilityCell Forge 1 (CF1), the Company’s wholly owned and fully integrated manufacturing facility, serves as a crucial strategic asset given the potential outlook for allogeneic CAR T product demand. We believe the ability to scale and control manufacturing will allow the Company to deliver a consistently high-quality allogeneic CAR T product. Financial Runway Extended into 2026The refined approach of the 2024 Platform Vision results in a streamlined trial footprint as well as a focused pipeline prioritization, allowing the Company to implement a planned restructuring of resources in Q1 2024. The result will reduce cash burn and is expected to extend the Company’s financial runway into 2026. Full 2024 guidance will be provided in the Company’s Q4/YE 2023 quarterly call.

Comprehensive Review of All Patients in the Phase 1 ALPHA/ALPHA2 Trials Demonstrate that Adding Investigational ALLO-647 to Standard Lymphodepletion Can Yield Durable Responses and a Safety Profile Comparable to Approved Autologous CAR T TherapiesCompany Received Fast Track Designation for ALLO-647 for Use in Adult Patients with Relapsed/Refractory Large B-Cell Lymphoma in November 2023 SOUTH SAN FRANCISCO, Calif., Dec. 09, 2023 (GLOBE NEWSWIRE) -- Allogene Therapeutics, Inc. (Nasdaq: ALLO), a clinical-stage biotechnology company pioneering the development of allogeneic CAR T (AlloCAR T™) products for cancer, today announced the presentation of data from a comprehensive safety review of patients treated in the Phase 1 ALPHA/ALPHA2 trials with ALLO-501/501A at the 65th Annual Meeting of the American Society of Hematology (ASH) in San Diego, CA. The safety review, which encompasses all 87 Phase 1 patients treated in both relapsed/refractory (r/r) Large B Cell Lymphoma (LBCL) and follicular lymphoma (FL), demonstrates that investigational ALLO-647 added to standard lymphodepletion can safely provide a window for the expansion and persistence of AlloCAR T cells, and has the potential to induce deep and durable remissions in relapsed and treatment-refractory cancers. "We believe in the immense potential of off-the-shelf CAR T products to not only address the limitations of current autologous CAR T cell therapy, but to also provide greater access to patients in need,” said Zachary Roberts, M.D., Ph.D., Executive Vice President of Research & Development and Chief Medical Officer of Allogene. “We fully understand the importance of lymphodepletion to achieving optimal outcomes, and ALLO-647 is just the first generation of our innovative approaches to enhancing lymphodepletion to promote expansion of CAR T cells.” The inclusion of our ALLO-647 candidate in the lymphodepletion regimen is designed to selectively prevent host rejection of allogeneic CAR T cell products. As previously presented in the Phase 1 ALPHA/ALPHA2 studies1, CAR T cell-naive patients with r/r LBCL were able to obtain a durable response, including a complete remission rate of 42% and a median duration of response of 23.1 months. In the studies, lymphodepletion consisted of three daily doses of fludarabine 30 mg/m2 and cyclophosphamide 300-500 mg/m2 (FC) and 39, 60, or 90 mg of ALLO-647 in divided doses prior to ALLO-501/501A infusion. The addition of ALLO-647 to standard lymphodepletion did not result in adverse events beyond those commonly observed with autologous CAR T cell therapy. No unexpected safety concerns were observed. Neutropenia and anemia were the most common any-grade treatment-emergent adverse events (or TEAEs) and neutropenia, anemia, and thrombocytopenia were the most common Grade 3 or higher TEAEs. Grade 3 or higher cytopenias decreased over time from Day 28 to Month 4 and were consistent across all subsets of patients. Incidence of Grade 3 or higher cytopenias were consistent with that reported for autologous CAR T cell therapy.2-4 Safety: TEAEs of Special Interest TEAEs, n (%)All (N=87)LBCLFL (n=26)All LBCL (n=61)CAR T Cell–Naive Pts Who ReceivedALLO-501/501A Manufactured WithThe Phase 2 Selected Process (n=33)Any GradeGrade ≥3Any GradeGrade ≥3Any GradeGrade ≥3Any GradeGrade ≥3CRS21 (24)1 (1)17 (28)1 (2)8 (24)04 (15)0ICANS1 (1)01 (2)00000Neurotoxicity24 (28)3 (3)19 (31)3 (5)13 (39)2 (6)5 (19)0GvHD00000000IRR48 (55)5 (6)31 (51)4 (7)16 (48)3 (9)17(65)1 (4)Infections50 (57)18 (21)34 (56)13 (21)19 (58)5 (15)16 (62)5 (19) There were no reports of graft-versus-host disease (GvHD) or Grade 3 or higher immune effector cell-associated neurotoxicity syndrome (ICANS). In total, 24% of patients experienced low-grade CRS, and there was 1 Grade 3 CRS event. Infection events were primarily low grade and manageable, with the most common being cytomegalovirus reactivation with an any-grade incidence of 25% and a Grade 3 or higher incidence of 9%. Incidence of infections were consistent with that reported for autologous therapy following lymphodepletion (12%-33% percent of patients).3-5 Eight patients experienced fatal adverse events not related to study treatment. The EXPAND trial, currently enrolling in the United States and Europe, is expected to support licensure of ALLO-647, used in conjunction with standard low-dose FC lymphodepletion regimens. The trial will enroll approximately 70 patients with r/r LBCL who will be randomized to lymphodepletion with FCA90 (which includes 90 mg of ALLO-647) versus FC alone before receiving a single 120 million cell dose of ALLO-501A. The primary endpoint of the study is progression free survival (PFS). Separately, the Company announced that the U.S. Food and Drug Administration (FDA) granted Fast Track Designation (FTD) for the investigation of ALLO-647 in adult patients with r/r LBCL based on its potential to enhance standard lymphodepletion. FTD designation is intended to accelerate the development and review of treatments for serious and life-threatening diseases where no treatment exists or where the treatment in discovery may be better than what is currently available. ALLO-647 is investigated as a lymphodepleting agent in combination with flu/cy prior to infusion of allogeneic CD19-directed CAR T cells with genomes edited to knock out CD52. About ALLO-501 and ALLO-501AALLO-501 and ALLO-501A are anti-CD19 AlloCAR TTM investigational products for the treatment of large B cell lymphoma. ALLO-501A, a next-generation anti-CD19 AlloCAR TTM product, eliminates the rituximab recognition domains in ALLO-501, which could allow for use in a broader patient population, including NHL patients with recent rituximab exposure. This product candidate is currently being studied in an ongoing potentially pivotal Phase 2 trial.
