Immuno-Oncology Pipeline:

Bempegaldesleukin (BEMPEG; NKTR-214):

Bempegaldesleukin (an immunostimulatory IL-2 cytokine prodrug which has been engineered to deliver a controlled, sustained, and preferential IL-2 pathway signal) in combination with a checkpoint inhibitor, leverages two immuno-oncology pathways with the aim of addressing the unmet needs of patients living with cancer.

Skin Cancer (1L Metastatic Melanoma and Adjuvant Melanoma):

Bladder Cancer (1L Metastatic Urothelial Carcinoma (mUC) and Muscle Invasive Bladder Cancer (MIBC)):

Kidney Cancer (1L Advanced Renal Cell Carcinoma (RCC)):

Lung Cancer (1L Non-Small Cell Lung Cancer (NSCLC)):


NKTR-255 is an investigational IL-15 agonist that is designed to engage the IL-15 pathway to increase both NK cell proliferation and activation and proliferation and survival of CD8+ T cells.

Multiple Myeloma and Non-Hodgkin's Lymphoma:

Relapsed or Refractory Solid Tumors:


NKTR-262 is an investigational novel small molecule agonist designed to activate toll-like receptors (TLR 7/8), promoting TLR activation to induce the generation of antigen-specific cytotoxic T cells to the patient’s specific tumor.

Relapsed/Refractory Metastatic Melanoma:
