Allogene Therapeutics Announces Poster Presentations at the 65th Annual Meeting of the American Society of Hematology
- Comprehensive Review of Overall Treatment Safety Profile of our ALLO-501/501A Candidate Used in Conjunction with Propriety Lymphodepletion with Investigational ALLO-647 from the Phase 1 ALPHA/ALPHA2 Studies
- Translational Overview of Patient Alloimmune Responses Affecting Allogeneic CAR T Cell Expansion and Rejection in Large B-Cell Lymphoma
“All CAR T cells require lymphodepletion to support the expansion and persistence needed to eradicate malignant cells. Because of the risk of allorejection by the patient’s immune system, creating the necessary window of persistence for an off-the-shelf, allogeneic CAR T product may require an enhanced approach to lymphodepletion. These results reinforce our belief that Allogene’s strategy of adding ALLO-647, an anti-CD52 monoclonal antibody candidate, to the standard fludarabine/cyclophosphamide (flu/cy) lymphodepletion regimen in our ALPHA/ALPHA2 studies can safely achieve this,” said
The first poster is a comprehensive safety review of all 85 patients treated in the Phase 1 ALPHA/ALPHA2 studies in relapsed/refractory (r/r) Large B Cell Lymphoma (LBCL) and follicular lymphoma (FL) to characterize the overall safety profile when ALLO-647 is added to standard lymphodepletion.

About ALLO-501 and ALLO-501A
ALLO-501 and ALLO-501A are anti-CD19 AlloCAR T investigational products for the treatment of large B cell lymphoma. ALLO-501A, a next-generation anti-CD19 AlloCAR T, 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. In

Forward-looking statements include statements regarding intentions, beliefs, projections, outlook, analyses or current expectations concerning, among other things: Allogene’s ability to deliver readily available off-the shelf cell therapy on-demand, more reliably, and at greater scale to more patients; and the modes of action, the therapeutic effects and safety profile of Allogene’s product candidates including their ability to treat cancers at various stages or to treat broad populations. Various factors may cause material differences between Allogene’s expectations and actual results, including risks and uncertainties related to: our product candidates are based on novel technologies, which makes it difficult to predict the time and cost of product candidate development and obtaining regulatory approval; the FDA may disagree with our regulatory plan and we may fail to obtain regulatory approval of our CAR T cell product candidates; and our clinical trials may fail to demonstrate the safety and efficacy of any of our product candidates, which would prevent or delay regulatory approval and commercialization. These and other risks are discussed in greater detail in Allogene’s filings with the SEC, including without limitation under the “Risk Factor” Heading in its Form 10-Q filed for the quarter ended September 30, 2023, being filed with the
Caution should be exercised regarding statements comparing autologous CAR T data. There are differences in the clinical trial design, patient populations, published data, follow-up times and the product candidates themselves, and the results from the clinical trials of autologous products may have no interpretative value on Allogene’s existing or future results.
