Researchers believe that the area surrounding the tumor, called the lymphoma microenvironment (LME), plays a major role in why treatments fail.\n\nIn this study, researchers will classify patients into four different LME subtypes (GC, IN, ME, or DE) using a standard lab test on their tumor samples. Patients will then be randomly assigned to one of two groups. The control group will receive a standard single-drug therapy (glofitamab). The experimental group will receive a tailored combination therapy based specifically on their tumor's LME subtype. The main hypothesis of this study is that customizing the treatment based on the tumor's microenvironment will significantly improve how long patients live without their disease getting worse (progression-free survival) compared to the standard single-drug approach.",[74],"Large B-cell Lymphoma",[76,77,78],"Large B-Cell Lymphoma (LBCL)","CAR-T Failure","Lymphoma Microenvironment (LME)","NOT_YET_RECRUITING","2026-05-15",{"date":82,"type":83},"2026-05-22","ACTUAL",{"date":85,"type":68},"2026-05-14",{"date":87,"type":68},"2028-11-01",{"name":5,"class":6},1]
