NKTR-255 in Combination With CAR-T Cell Therapy for the Treatment of Relapsed or Refractory Large B-cell Lymphoma (NCT05359211)
A Phase Ib Open-Label Study Evaluating the Safety and Efficacy of NKTR-255 in Combination With CD19-Directed CAR-T Cell Therapy in Patients With Relapsed/Refractory (R/R) Large B-Cell Lymphoma (LBCL)
🩺 Plain-English Summary (8th-Grade Level)
This phase Ib trial studies the effects of NKTR-255 in combination with chimeric antigen (CAR)-T cell therapy and to see how well they work in treating patients with large B-cell lymphoma that has come back (relapsed) or does not respond to treatment (refractory). NKTR-255 is an investigational IL-15 receptor agonist designed to boost the immune system's natural ability to fight cancer. T cells are infection fighting blood cells that can kill tumor cells. Lisocabtagene maraleucel is a CAR-T cell product that consists of genetically engineered T cells, modified to recognize CD19, a protein on the surface of cancer cells. These CD19-specific T cells may help the body's immune system identify and kill CD19-positive cancer cells. Giving NKTR-255 together with lisocabtagene maraleucel may work better in treating large B-cell lymphoma than either drug alone.
