Overview

In vitro and in vivo studies reveal NX-5948 reduces cytokine storm and promotes macrophage polarization in HLH, indicating a novel therapeutic approach.

Key Points

This analysis examines the efficacy and mechanisms of BTK degrader NX-5948 in treating HLH.
In vitro experiments using murine macrophage cell line RAW264.7 to model HLH-like inflammation
Comparison of NX-5948 with other BTK inhibitors and a JAK inhibitor
In vivo evaluation in C57/BL6 mice with secondary HLH induced by CpG injections
Measurement of drug effects on macrophage function, cytokine release, and BTK/NF-κB pathway activity
Histopathological analysis via H&E staining
NX-5948 reduced macrophage proliferation and exhibited a lower IC50 than comparator drugs
Induced macrophage apoptosis and shifted macrophage polarization from M1 to M2
In vivo, NX-5948 improved hepatosplenomegaly and increased platelet counts
Decreased serum cytokine levels of TNF-α, IL-6, and ferritin
No significant pathological changes in major organs observed after treatment with NX-5948.
