Galapagos Announces Oral Presentations at EHA and ICML 2025 Featuring Promising New Data from ATALANTA-1 study of Investigational CAR-T Candidate GLPG5101
Mechelen, Belgium; May 14, 2025, 22:01 CET; Galapagos NV (Euronext & NASDAQ: GLPG), a global biotechnology company dedicated to transforming patient outcomes through life-changing science and innovation, today announced that new data from our ongoing ATALANTA-1 Phase 1/2 study of GLPG5101 in relapsed/refractory non-Hodgkin lymphoma (R/R NHL) have been accepted for oral presentations at the 2025 European Hematology Association (EHA) Congress taking place June 12-15, 2025, in Milan, Italy, and the International Conference on Malignant Lymphoma (ICML) in Lugano, Switzerland the following week.
“At Galapagos, we are driven by a mission to expand access to transformative cell therapies for patients facing serious hematological and solid tumors, where unmet needs remain high,” said Omotayo Fasan, M.D., Clinical Development Program Head at Galapagos. “We are excited to present new data for GLPG5101 in multiple relapsed/refractory non-Hodgkin lymphoma subtypes, which continue to support our approach of rapidly delivering fresh, stem-like early memory cells to potentially improve outcomes.”
The data to be presented are summarized below:
- The oral presentation at EHA will feature new safety and longer follow-up data for GLPG5101 in 64 patients with R/R large B-cell lymphoma (DLBCL), mantle cell lymphoma (MCL), follicular lymphoma (FL), and marginal zone lymphoma (MZL) from the ongoing ATALANTA-1 Phase 1/2 study.
- The oral presentation at ICML will feature new and full results from ATALANTA-1 Cohort 3 (indolent NHL, iNHL) on safety, efficacy and translational data for GLPG5101 in patients with iNHL (follicular lymphoma and marginal zone lymphoma) from the ongoing ATALANTA-1 Phase 1/2 study.

About GLPG5101 and ATALANTA-1 (EudraCT 2021-003272-13; NCT 06561425)
GLPG5101 is a second generation anti-CD19/4-1BB CAR-T product candidate, administered as a single fixed intravenous dose. The safety, efficacy, and feasibility of decentralized manufactured GLPG5101 are currently being evaluated in the ATALANTA-1 Phase 1/2 study in patients with relapsed/refractory non-Hodgkin lymphoma (R/R NHL).
The primary objective of the Phase 1 part of the study is 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 decentralized manufacturing of GLPG5101. The dose levels that were evaluated in Phase 1 are 50x106 (DL1), 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 Rate (CRR), duration of response, progression free survival, overall survival, safety, pharmacokinetic profile, and the feasibility of decentralized manufacturing. Each enrolled patient will be followed for 24 months.
About Galapagos’ cell therapy manufacturing platform
Galapagos’ innovative decentralized cell therapy manufacturing platform has the potential for the administration of fresh, fit cells within a median vein-to-vein time of seven days, greater physician visibility, and 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.
