GLPG - Galapagos presents encouraging new data for CD19 CAR-T candidate GLPG5101 in non-Hodgkin lymphoma at EHA 2024 | Benzinga
Mechelen, Belgium; June 14, 2024, 22:01 CET; Galapagos NV ((Euronext &, NASDAQ:GLPG) today announced that it will present encouraging new data from the ongoing Phase 1/2 ATALANTA-1 study of CD19 CAR-T candidate, GLPG5101, in relapsed/refractory non-Hodgkin lymphoma (R/R NHL) at the annual European Hematology Association (EHA) 2024 Hybrid Congress. Galapagos' product candidate GLPG5101 is produced using the company's innovative, decentralized T-cell manufacturing platform.
The oral presentation includes updated safety and efficacy data for GLPG5101 in patients with diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), marginal zone lymphoma (MZL) and mantle cell lymphoma (MCL). The presentation also includes durability and cellular kinetics data. At the data cut-off date of December 20, 2023, no unexpected safety findings were observed and treatment with GLPG5101 resulted in high complete response rates in all indications in this heavily pretreated patient population.
GLPG5101 was administered as a fresh product in 94% of patients with a median vein-to-vein time of seven days, eliminating the need for bridging therapy. T-cell subsets were assessed in the apheresis starting material and final CAR-T product. There was a higher proportion of early phenotypes of CD4+ and CD8+ CAR T cells (naive/stem cell memory and central memory T cells) in the final product compared with starting material, indicating an increase of those populations during the manufacturing process. This demonstrates the feasibility of Galapagos' decentralized manufacturing platform to deliver a high-quality CAR T-cell product to patients.
The new data will be presented by Marie José Kersten, M.D., Professor of Hematology and Head of the Department of Hematology at the Amsterdam University Medical Center.
"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 are delighted to present promising new data for GLPG5101 at the EHA congress. The high complete response rates, combined with low-grade CRS and ICANS, demonstrates the potential of GLPG5101 in addressing the critical needs of this patient population. The data also confirm the feasibility of our innovative decentralized T-cell manufacturing platform in delivering fresh, fit cells with a median vein-to-vein time of just seven days."
Key new data from the ongoing Phase 1/2 ATALANTA-1 study include:
As of the data cut-off date of December 20, 2023, 34 patients (17 in Phase 1 and 17 in Phase 2) received GLPG5101 with a median vein-to-vein time of seven days. Overall, safety results were available for 33 patients and efficacy results were available for 31 patients. The data are summarized below:
- GLPG5101 showed an encouraging safety profile with most TEAEs1 of Grade 1 or 2; the majority of Grade ? 3 events were hematological. Two cases of CRS2 Grade 3 were observed in Phase 1 and one case of ICANS3 Grade 3 was observed in Phase 2.
- In Phase 1, 14 of 16 efficacy-evaluable patients responded to treatment (objective response rate, ORR 87.5%), with 12 patients achieving a complete response (CR) (CR rate, CRR 75%). In Phase 2, 14 of 15 efficacy-evaluable patients responded to treatment (ORR 93.3%), and all responders achieved a complete response (CRR 93.3%).
- High ORR and CRR were observed in the pooled Phase 1 and Phase 2 efficacy analysis set, split by indication:
- In patients with DLBCL, 7 of 9 efficacy-evaluable patients responded to treatment (ORR 78%), with 5 patients achieving a complete response (CRR ...
