Nektar Therapeutics Presents First Preclinical Data From Novel CSF-1 Program, NKTR-422, At 2024 American College Of Rheumatology Convergence; NKTR-422 Demonstrated Inflammation Resolution And Tissue Repair In Multiple Preclinical Models Of Chronic Inflammatory Conditions

- NKTR-422 demonstrated inflammation resolution and tissue repair in multiple preclinical models of chronic inflammatory conditions -

SAN FRANCISCO, Nov. 18, 2024 /PRNewswire/ -- Nektar Therapeutics (NASDAQ:NKTR) today announced its oral presentation highlighting preclinical data on NKTR-422 at the 2024 American College of Rheumatology (ACR) conference, being held in Washington, D.C. from November 14-19, 2024.

NKTR-422 is a novel modified hematopoietic colony stimulating factor (CSF) protein engineered to selectively modulate resolution processes of inflammation by targeting the expansion, reprograming and activation of anti-inflammatory tissue resident macrophages.

Currently approved inflammatory disease therapies are not designed to achieve inflammation resolution or tissue repair, which are both required for remission.1 Nektar has identified a CSF-1R agonist with a differentiated pharmacokinetic (PK)/pharmacodynamic (PD) profile compared to the native CSF-1 cytokine. Reduced clearance enables sustained PD activity from a single dose, unlike historical multiple dose per day necessary regimens of recombinant human CSF-1 administration. This CSF-1R agonist, NKTR-422, demonstrated inflammation resolution and tissue repair markers induction in tissue resident macrophages without induction of monocytosis and enhanced the efficacy of inflammatory cytokine blockade in rodent models.
