Nektar to present NKTR-255 combo poster at ASH meeting

Nektar Therapeutics announced that collaborators from the Cairo Laboratory at New York Medical College presented a poster highlighting new preclinical data on NKTR-255 at the 65th American Society of Hematology (ASH) Annual Meeting demonstrating that NKTR-255 significantly enhanced the cytotoxicity of expanded Natural Killer (NK) cells when combined with obinutuzumab against rituximab-resistant BL cells and significantly improved the survival of mice xenografted with Raji-4RH compared to controls. NKTR-255 is a novel polymer-conjugated human IL-15 receptor agonist currently being studied in three separate clinical studies in combination with cell therapies and immunotherapies. Preclinical and early clinical data suggest that NKTR-255 can improve proliferation and persistence of NK and CD8+ T cells to enhance specific anti-tumor activity.
