Maybe I’m a little late. But in december Nektar announced the following:
Nektar Therapeutics (NASDAQ:NKTR) today announced that dosing has commenced in the Phase 1/2 clinical study evaluating the efficacy and safety of NKTR-214 in the treatment of solid tumors. NKTR-214 is a novel CD122-biased cytokine designed to preferentially activate the beta and gamma sub-units of the IL-2 receptor in order to proliferate tumor-killing T cells within the body (CD8-positive effector T cells and natural killer T cells) without stimulating regulatory T cells (CD4-positive T cells). That’s some very nice news and the stocprice jumped.
