Mavrilimumab is a human monoclonal antibody[1] that inhibits human granulocyte macrophage colony-stimulating factor receptor (GM-CSF-R).[2]


Mavrilimumab was discovered as CAM-3001 by Cambridge Antibody Technology and is being developed by MedImmune, Inc.[3] as an investigational drug for the treatment of rheumatoid arthritis


Mavrilimumab has been studied in a phase 1 dose-ranging trial[2] and a phase 2a clinical trial, both sponsored by Medimmune.[4] The phase 2a trial, which studied mavrilimumab doses of up to 100 mg, reported that 55.7% of subjects met the primary endpoint of a ≥1.2 decrease from baseline in disease activity scores at week 12 (vs. only 34.7% of placebo subjects).[4]


As of 2013, two further clinical studies were reported to be underway in rheumatoid arthritis patients to investigate these effects further.[5]


In early 2017 the phase IIb study was reported to be showing promising results.[6]
