Phase I/II Trials Advancing

Developing novel therapies for neuroinflammatory diseases

Artielle Immunotherapeutics is a venture-backed company pioneering a first-in-class therapeutic platform (DRhQ) to treat neuroinflammatory conditions and advanced cancers — based on groundbreaking research from OHSU and VA Portland Healthcare System.

Disease indications being targeted

A novel, differentiated mechanism of action

Artielle's lead molecule, DRhQ, targets the CD74 receptor on monocytes and inflammatory T cells and blocks the action of macrophage migration inhibitory factor (MIF) — a key inflammatory cytokine elevated in MS and many other diseases. This dual-action approach reverses the chemotactic gradient attracting inflammatory cells to CNS injury sites and promotes apoptosis of destructive infiltrating cells.

1

CD74 Receptor Targeting

DRhQ competitively inhibits MIF binding to the CD74 receptor on monocytes and T cells.

2

Chemotactic Gradient Reversal

Blocks pro-inflammatory signaling, reversing the attraction of peripheral cells to CNS injury sites.

3

Neuroprotective Reprogramming

Promotes apoptosis of infiltrating cells and reprograms microglia and astrocytes toward neuroprotection.
