That news comes from UCB, the drug company that makes Cimzia.
Cimzia targets an inflammatory compound called TNF-alpha. It's given by injection at intervals of every two weeks or every four weeks, alone or with another drug called methotrexate.
In a news release, UCB states that the FDA approved Cimzia to treat rheumatoid arthritis based on clinical trials in which more than 2,300 rheumatoid arthritis patients taking Cimzia with another drug, methotrexate, had a greater reduction in signs and symptoms of RA after 24 weeks of treatment, compared to patients only taking methotrexate. Some patients showed clinical responses to Cimzia plus methotrexate within one to two weeks.
Patients taking Cimzia and methotrexate also had a slower progression of joint damage during the trial than patients only taking methotrexate, according to UCB.
