Branded Amtagvi, lifileucel is cleared for use in patients with unresectable or metastatic melanoma previously treated with a PD-1 blocking antibody, and if BRAF V600 mutation-positive, a BRAF inhibitor with or without a MEK inhibitor

Previous research has validated hematopoietic progenitor kinase 1 (HPK1) as a target in immune oncology, and pharmacological inhibition of HPK1 has been shown to enhance effector T-cell function and antitumor activity.
As a cytokine used in the field of immuno-oncology, interleukin-2 (IL-2) can produce durable and even complete responses in some patients, as well as induce immune memory against tumors. However, its rapid metabolism within the body means it has a short serum half-life, so it needs to be given in high doses, which can trigger severe side effects.
When Nektar Therapeutics Inc. decided to push ahead with development of Treg stimulator rezpegaldesleukin (rezpeg) in atopic dermatitis despite what appeared to be middling early stage data, investors weren’t exactly jumping up and down.
