Erlizumab, also known as rhuMAb, is a recombinant humanized monoclonal antibody that was an experimental immunosuppressive drug. Erlizumab was developed by Genentech under a partnership with Roche to treat heart attack, stroke, and traumatic shock.[1]


Mechanism of action

The drug works by blocking a growth factor in blood vessels.[2] Specifically, erlizumab targets CD18 and an LFA-1 integrin.[3] Erlizumab was meant to stop lymphocyte movement into inflamed tissue, thereby reducing tissue damage.[4]

Clinical trials

Genentech started clinical trials on the drug in October 1996.[5] During clinical trials, six patients suddenly started coughing up blood, and four of them later died.[2] In June 2000, preliminary phase II clinical trial results showed that erlizumab did not meet Genentech's goals.[1] Genentech's primary goal was for the drug to increase blood flow to the heart within 90 minutes of administering the medicine.[4]

Other anti-CD18 drugs

Multiple companies have tried to develop anti-CD18 drugs, but none of them have been successful.[4] Among them are Icos's rovelizumab (LeukArrest), and two drugs developed by Protein Design Labs (PDL) and Centocor.[4] Although trials in humans have not gone well, the research of CD18 drugs in animals has been encouraging.[4] It is thought that the experimental medicines are affecting the lymphocyte adhesion pathway in humans in unintended ways.[4] One hypothesis is that the endothelial cell barrier function fails when blood supply is low for a prolonged time in humans.[6] If this is true, the drug is not able to stop lymphocyte movement into inflamed tissue.[6]
