Galapagos’ Cell Therapy Exit Amid Promising GLPG5101 Data Might Change The Case For Investing In Galapagos (ENXTAM:GLPG)

Simply Wall St · 2d ago
  • In early December 2025, Galapagos NV reported updated Phase 2 ATALANTA-1 data showing high complete response rates and durable outcomes for its CD19 CAR T-cell candidate GLPG5101 in high-risk mantle cell lymphoma, with rapid manufacturing timelines and limited severe toxicities.
  • On the same occasion, Galapagos confirmed plans to wind down its cell therapy activities, while remaining open to a potential sale, highlighting a contrast between promising clinical results and a retreat from in-house cell therapy operations.
  • We will now examine how Galapagos’s plan to wind down its cell therapy business, despite promising GLPG5101 data, shapes its investment narrative.

What Is Galapagos' Investment Narrative?

To own Galapagos today, you have to believe that the company can turn a sizeable, loss-making R&D engine into a focused, cash-disciplined biotech with a few value-driving assets at its core. The updated ATALANTA-1 data strengthen the scientific case for GLPG5101, but the decision to wind down cell therapy means the near-term story now tilts more toward portfolio rationalization, cost restructuring and what, if anything, Galapagos can realize from a sale of the cell therapy unit. With revenue expected to contract and a new CEO and leadership team still bedding in, execution risk and visibility on the future pipeline become more important short-term drivers than this single data readout. So while the GLPG5101 news is clinically encouraging, it may not be the main financial catalyst most shareholders are waiting for.

The valuation report we've compiled suggests that Galapagos' current price could be inflated.
