Galapagos NV and CellPoint presented encouraging initial data from the ongoing ATALANTA-1 Phase 1/2 study with GLPG5101 at the 64th Annual American Society of Hematology Congress taking place in New Orleans, Louisiana, from 10-13 December.
- 6 out of 7 eligible patients with relapsed/refractory Non-Hodgkin Lymphoma (rrNHL) responded to treatment (ORR of 86%) and all responding patients achieved complete response (CR)
- No grade 3 or higher cytokine release syndrome (CRS) or immune effector cell-associated neurotoxicity syndrome (ICANS) was observed in any of the eligible patients
- Initial data suggest the potential of our decentralized manufacturing and supply model for faster, convenient, and efficient delivery of GLPG5101 at the point-of-care
Mechelen, Belgium; 13 December 2022, 7.00 CET; Galapagos NV (Euronext & NASDAQ: GLPG) and CellPoint (a Galapagos company)today presented encouraging initial data from the ongoing ATALANTA-1 Phase 1/2 study with GLPG5101 at the 64th Annual American Society of Hematology (ASH)Congress taking place in New Orleans, Louisiana, from 10-13 December.
ATALANTA-1 is a Phase 1/2 study in heavily pre-treated rrNHL patients to evaluate the safety, efficacy, and feasibility of GLPG5101, a fresh CD19 CAR-T product candidate manufactured at point-of-care. The dose levels that are evaluated in the Phase 1 part of the study are 50x106 (DL1), 110x106 (DL2) and 250x106 (DL3). As of 8 November 2022, 9 patients were enrolled; baseline and safety data for 8 patients were available (n=4 at DL1; n=4 at DL2). 7 patients reached the follow-up period of 28-days and were eligible for efficacy evaluation.
The initial results from 7 patients that were eligible for efficacy evaluation (cut-off date: 8 November 2022) indicated that a 7-day vein-to-vein time is feasible and demonstrated strong and consistent in vivo CAR-T expansion levels. Moreover, the initial efficacy results are encouraging with an objective response rate (ORR) of 86% observed and all responding patients achieving a complete response (CR). A duration of response of up to 7 months has been reported and follow-up is ongoing. Two patients who received DL1 that progressed after initial stable disease or CR respectively, had a CD19-negative escape. No CD19-positive relapses have been observed.
In the safety analysis of these 7 patients, adverse events were consistent with the known toxicities of CD19 CAR-T treatment. No grade 3 or higher cytokine release syndrome (CRS) or immune effector cell-associated neurotoxicity syndrome (ICANS) was observed in any of the patients. At DL2, CRS grade 1 or 2 was reported in 4 patients and ICANS grade 1 was reported in 3 patients. Patients at DL1 did not experience any grade of CRS or ICANS. Dose-limiting toxicity (neutropenia grade 4 for >21 days) was observed in 1 patient (DL2) and the majority of grade ≥3 adverse events were hematological toxicities.
“We are committed to accelerating transformational innovation to address unmet needs of patients with advanced cancers,” said Dr. Paul Stoffels1, CEO and Chairman of the Board of Directors of Galapagos. “Despite significant medical advancements in recent years, many cancer patients relapse, become resistant to treatment or are diagnosed too late. We believe that differentiation and broader access to therapy can come from a disruptive CAR-T manufacturing model at the point-of-care, closer to patients. We are excited to present initial encouraging safety, efficacy and feasibility data from the ATALANTA-1 study with GLPG5101 manufactured at point-of-care, which support that potential. We are on track to report topline data from the completed study in the first half of 2023.”
The poster presentation was given by Marie José Kersten, MD, PhD, Professor of Hematology and Head of the Department of Hematology at the Academic Center in Amsterdam:

CellPoint has developed, in a strategic collaboration with Lonza, a novel point-of-care supply model, which is designed to enable clinicians to administer fresh CAR T cells within 7 days of leukapheresis, without complex logistics or cryopreservation, thereby aiming to address important limitations of current CAR-T treatments. The proprietary platform consists of CellPoint’s end-to-end xCellit workflow management and monitoring software and Lonza’s Cocoon® Platform, a functionally closed, automated manufacturing platform for cell therapies.
About theATALANTA-1 study (EudraCT 2021-003272-13)
ATALANTA-1 is an ongoing Phase 1/2, open-label, multicenter study to evaluate the feasibility, safety, and efficacy 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 an intravenous infusion of a fresh product candidate in a single fixed dose. Each enrolled patient will be followed for 24 months. 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 point-of-care manufacturing of GLPG5101. The planned dose levels that are evaluated in the Phase 1 are 50x106, 110x106 and 250x106 CAR 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 feasibility of point-of-care manufacturing. The study is currently enrolling rrNHL patients in Europe and the first expansion cohort for Mantle Cell Lymphoma, a form of NHL, is currently open for recruitment. The company aims to broaden the study to include US patients in 2023 and to provide topline results in the first half of 2023.
About Non-Hodgkin’s Lymphoma
Non-Hodgkin’s lymphoma is a cancer originating from lymphocytes, a type of white blood cell which is part of the body’s immune system. Non-Hodgkin’s lymphoma can occur at any age although it is more common in adults over 50 years old. Initial symptoms usually are enlarged lymph nodes, fever, and weight loss. There are many different types of Non-Hodgkin’s lymphoma. These types can be divided into aggressive (fast-growing) and indolent (slow-growing) types, and they can be formed from either B lymphocytes (B cells) or in lesser extent from T lymphocytes (T cells) or Natural Killer cells (NK cells). B-cell lymphoma makes up about 85 percent of Non-Hodgkin’s lymphomas diagnosed in the US. Prognosis and treatment of Non-Hodgkin’s lymphomas depend on the stage and type of disease.
