Outlook 2024 Financial outlook For the full year 2024, we reconfirm our cash burn guidance of €280 million to €320 million (compared to €414.8 million for the full year 2023), not including future potential business development opportunities. R&D Outlook We are progressing three CAR-T Phase 1/2 studies in hemato-oncology: GLPG5101 in relapsed/refractory NHL; GLPG5201 in relapsed/refractory CLL, and RT; andGLPG5301 in relapsed/refractory multiple myeloma. We are progressing two Phase 2 studies with TYK2 inhibitor GLPG3667, in systemic lupus erythematosus and in dermatomyositis. We plan to file Investigational New Drug applications in the U.S. to progress clinical development of our CAR-T programs in hemato-oncology. We will further upscale our CAR-T network and operations in the U.S. and Europe. Business development We will continue to evaluate business development opportunities that fit our strategy to accelerate and expand our pipeline of potential best-in-class investigational medicines in our therapeutic focus areas of oncology and immunology.

Two oral presentations and one poster on encore preliminary data from Phase 1/2 CD19 CAR-T studies in non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukemia (CLL) / Richter transformation (RT) Mechelen, Belgium; 4 April 2024, 22:01 CET – Galapagos NV (Euronext & NASDAQ: GLPG) today announced that four abstracts, including two oral presentations on encore preliminary clinical and translational data for its seven-day vein-to-vein CAR-T product candidates GLPG5101 and GLPG5201, will be presented at the 50th Annual Meeting of the European Society for Blood and Marrow Transplantation (EBMT) to be held in Glasgow, UK, on 14-17 April 2024. ATALANTA-1 and EUPLAGIA-1 are ongoing Phase 1/2 open-label, multi-center studies designed to assess the safety, efficacy and feasibility of point-of-care manufactured GLPG5101 and GLPG5201 in patients with relapsed/refractory NHL, and relapsed/refractory CLL and RT, respectively. The primary objective of the Phase 1 part of the studies is to evaluate the safety and preliminary efficacy to determine the recommended dose for the Phase 2 part of the study. The primary objective of the Phase 2 part of the studies 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. GLPG5101 and GLPG5201 are second generation anti-CD19/4-1BB CAR-T product candidates, administered as a single fixed intravenous dose. “We are committed to accelerating breakthrough innovations to extend the reach of CAR-T therapies to patients with rapidly progressing cancers,” said Dr. Jeevan Shetty, M.D., Head of Clinical Development Oncology at Galapagos. “We believe that the preliminary safety and efficacy data from our ongoing Phase 1/2 studies with our CD19 CAR-T therapy candidates in patients with relapsed/refractory NHL, CLL and RT, combined with our unique, innovative decentralized manufacturing approach that enables a seven-day vein-to-vein time, support the promise of GLPG5101 and GLPG5201 in addressing the critical needs of patients facing poor prognosis.” The following table provides a summary of Galapagos’ presentations at EBMT 2024: Abstract Title Authors/Presenter Presentation date/time Galapagos encore abstracts Seven-Day Vein-to-Vein Point-of-Care Manufactured CD19 CAR T-Cell Therapy (GLPG5101) in Relapsed/Refractory Non-Hodgkin Lymphoma (NHL): Results from the Phase 1 ATALANTA-1 Trial Marie José Kersten, Kirsten Saevels, Sophie Servais, Yves Beguin, Joost S.P.

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. About the ATALANTA-1 study (EudraCT 2021-003272-13)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 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 is to evaluate the safety and preliminary efficacy 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. About the EUPLAGIA-1 study (EudraCT 2021-003815-25)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 chronic 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 is to evaluate the safety and preliminary efficacy to 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.
