The double-blind period was followed by the open-label extension phase in which all patients could receive HUMIRA (40 mg every other week) for up to an additional 144 weeks (n=179). During the open-label extension phase of the study, both the investigator and the patient knew that the patient was receiving HUMIRA. Baseline demographics and disease characteristics were comparable between patients who entered the open-label period and those of patients who were initially randomized.About HUMIRA ® (adalimumab) UsesHUMIRA (adalimumab) is a prescription used to reduce the signs and symptoms of ankylosing spondylitis in adults. HUMIRA is used alone or with certain other medicines to reduce the signs and symptoms of psoriatic arthritis in adults. It may prevent further damage to bones and joints and may help with the ability to perform daily activities. Important Safety Information HUMIRA is a TNF blocker medicine that affects the immune system and can lower the ability to fight infections. Serious infections have happened in people taking HUMIRA. These serious infections include tuberculosis (TB) and infections caused by viruses, fungi, or bacteria that have spread throughout the body. Some people have died from these infections. People should be tested for TB before HUMIRA use and monitored for signs and symptoms of TB during therapy. People at risk of TB may be treated with medicine for TB. Treatment with HUMIRA should not be started in a person with an active infection, unless approved by a doctor. HUMIRA should be stopped if a person develops a serious infection. People should tell their doctor if they live in or have been to a region where certain fungal infections are common, have had TB, hepatitis B, are prone to infections, or have symptoms such as fever, fatigue, cough, or sores. For people taking TNF blockers, including HUMIRA, the chance of getting lymphoma or other cancers may increase. Some people have developed a rare type of cancer called hepatosplenic T-cell lymphoma. This type of cancer often results in death. If using TNF blockers including HUMIRA, the chance of getting two types of skin cancer (basal cell and squamous cell) may increase. These types are generally not life threatening if treated.
