Galapagos NV to Present New Preliminary Translational Data at EBMT-EHA Annual Meeting 2024
Galapagos NV to present new preliminary translational data and previously disclosed data at the European Society for Blood and Marrow Transplantation (EBMT)-European Hematology Association (EHA) 6th European CAR T-cell meeting taking place from 15–17 February 2024 in Valencia, Spain. The preliminary translational data from its EUPLAGIA-1 Phase 1/2 study demonstrate that Galapagos’ differentiated point-of-care manufacturing platform offers the potential for a single infusion of fresh early-phenotype CD19 CAR-T cells with robust expansion and persistence in patients with relapsed/refractory chronic lymphocytic leukemia (rrCLL) and patients with Richter transformation (RT). Further, previously disclosed safety, efficacy and feasibility data from EUPLAGIA-1 and ATALANTA-1 support the potential of Galapagos’ innovative approach to CAR-T manufacturing and of the transformational impact on patients with severe hematologic cancers. Patient recruitment of the Phase 1 dose-finding part of EUPLAGIA-1 has been completed and 15 patients were enrolled (6 at dose level 1 (DL1); and 9 at dose level 2 (DL2)), all of whom were diagnosed with rrCLL and 9 with additional RT. All 15 Phase 1 batches were manufactured at the point-of-care and infused as a single fresh, fit product within a median vein-to-vein time of seven days, with 80% of patients receiving the product in seven days. GLPG5201 final product showed an increase in early phenotypes of CD4+ and CD8+ CAR-T cells (naïve, stem cell memory (TN/SCM) and central memory) compared to apheresis starting material. A robust in vivo expansion of GLPG5201 occurred with a median time-to-peak expansion of 14 days, regardless of dose level, and a higher exposure for patients infused with DL2 compared to DL1. GLPG5201 expansion and exposure were similar in patients with rrCLL and in patients with RT. Persisting CAR-T cells were detected up to 15 months post-infusion. Moreover, the abundance of both CD4+ and CD8+ TN/SCM CAR-T cells in the final product correlated with CAR-T-cell exposure in patients. Galapagos’ decentralized, innovative point-of-care CAR T-cell manufacturing platform offers the potential for the administration of fresh, fit cells with a vein-to-vein time of seven days, greater physician control and a significantly improved patient experience. The platform consists of an end-to-end xCellit™ workflow management and monitoring software system, a decentralized, functionally closed, automated manufacturing platform for cell therapies (using Lonza’s Cocoon®) and a proprietary quality control testing and release strategy. EUPLAGIA-1 is an ongoing Phase 1/2 open-label, multi-center study evaluating the safety, efficacy and feasibility of point-of-care manufactured GLPG5201, a CD19 CAR-T product candidate, in patients with relapsed/refractory lymphocytic leukemia (rrCLL) and small cell lymphocytic lymphoma (rrSLL), with or without Richter transformation (RT). GLPG5201 is a second generation anti-CD19/4-1BB CAR-T product candidate, administered as a single fixed intravenous dose. Patients with CD19+ rrCLL or rrSLL with =2 lines of prior therapy are eligible to participate, and patients with RT are eligible regardless of prior therapy. The primary objective of the Phase 1 part of the study was to evaluate safety and determine the recommended dose for the Phase 2 part of the study. The dose levels that were evaluated in the Phase 1 part of the study are 35x106 (DL1), and 100x106 (DL2) CAR+ viable T cells. The primary objective of the Phase 2 part of the study is to assess the Objective Response Rate (ORR) and the secondary objectives include the analysis of the Complete Response (CR), duration of response, progression free survival, overall survival, safety, pharmacokinetic profile, and feasibility of point-of-care manufacturing. ATALANTA-1 is an ongoing Phase 1/2, open-label, multicenter study to evaluate the safety, efficacy and feasibility of point-of-care manufactured GLPG5101, a CD19 CAR-T product candidate, in patients with relapsed/refractory non-Hodgkin’s lymphoma (rrNHL). GLPG5101 is a second generation anti-CD19/4-1BB CAR-T product candidate, administered as a single fixed intravenous dose. The primary objective of the Phase 1 part of the study was to evaluate safety and to determine the recommended dose for the Phase 2 part of the study. Secondary objectives include assessment of efficacy and feasibility of near the point-of-care manufacturing of GLPG5101. The dose levels that were evaluated in Phase 1 are 50x106 (DL1) and 110x106 (DL2) and 250x106 (DL3) CAR+ viable T cells. The primary objective of the Phase 2 part of the study is to evaluate the Objective Response Rate (ORR) while the secondary objectives include Complete Response (CR), duration of response, progression free survival, overall survival, safety, pharmacokinetic profile, and the feasibility of point-of-care manufacturing. Each enrolled patient will be followed for 24 months. PAPILIO-1 is a Phase 1/2, open-label, multicenter study to evaluate the safety, efficacy and feasibility of point-of-care manufactured GLPG5301, a BCMA CAR-T product candidate, in patients with relapsed/refractory multiple myeloma (rrMM) after =2 prior lines of therapy. The primary objective of the Phase 1 part of the PAPILIO-1 study is to evaluate safety and determine the recommended dose for the Phase 2 part of the study. The primary objective of the Phase 2 part of the study is to evaluate the efficacy of GLPG5301, as measured by the Objective Response Rate (ORR). Secondary objectives for both Phase 1 and Phase 2 include further assessment of the safety of GLPG5301, additional efficacy endpoints, including assessment of Minimal Residual Disease (MRD), as well as the feasibility of point-of-care manufacture of GLPG5301 in rrMM patients. Each enrolled patient will be followed for 24 months. During Phase 1, up to 3 dose levels will be evaluated and at least 12 patients will be enrolled to establish the recommended Phase 2 dose. Approximately 30 additional patients will be enrolled in the Phase 2 part of the study to further evaluate the safety and efficacy of GLPG5301.
