This study is evaluating whether an experimental treatment called GLPG5101 helps to treat non-Hodgkin lymphoma (NHL) and if it is safe to use. This study will be carried out in 2 phases: * The first phase is to see which doses of GLPG5101 work best with the least number of side effects. * In the second phase, participants will receive the selected dose(s) based on the results in the first phase.
Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.
Phase 2 trials begin testing efficacy in a larger patient group (100–300). This is often where biotech binary events occur — positive Phase 2 data can significantly advance a company's pipeline narrative, while failures can be terminal for a program.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
Galapagos NV (GLPG) is the sponsoring company for this trial. BiotechSign currently grades this company F (23/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
