Dr. Mease: Clinical trials are medical research studies that test the safety and effectiveness of a drug. BENLYSTA was tested in the largest clinical trial program involving people with systemic lupus erythematosus ever conducted. This clinical trial program involved three different trials and involved 2,133 patients.

In the trials of BENLYSTA, BENLYSTA was added to other treatments. These treatments, which varied among the people who participated in the trials, are accepted by experts and widely used to treat lupus symptoms including steroids, nonsteroidal anti-inflammatory drugs, also called NSAIDS, antimalarials and immunosuppressants.

Dr. Mease: The results of these clinical trials showed that BENLYSTA plus other lupus treatments was superior to other lupus treatments alone in reducing lupus disease activity. The reduction in disease activity seen with BENLYSTA plus other lupus treatments was mainly due to improvements in parts of the body most commonly affected among the participants in the trials. These body areas included the skin, the mouth, the joints and muscles and the immune system.

Dr. Mease: In a person with lupus, some B cells, called autoreactive B cells, react against your own body. These cells contribute to symptoms of lupus.

Dr. Mease: Researchers have discovered a protein known by the abbreviation B-L-Y-S, or BLyS, which stimulates the growth of these autoreactive B cells. BENLYSTA works by binding to the BLyS protein. In other words, BENLYSTA prevents BLyS from stimulating the type of B cells that have been associated with lupus. So adding BENLYSTA to your lupus treatments may help reduce the abnormal immune system activity seen in lupus.

Dr. Mease: It is important to know that BENLYSTA is not a steroid. BENLYSTA contains belimumab, which belongs to a group of drugs called monoclonal antibodies. These are large, complex proteins produced in laboratories. Monoclonal antibodies copy the disease fighting response of your natural antibodies.

Dr. Mease: Drugs, such as BENLYSTA, which are made of complex proteins, cannot be taken by mouth. That's because these protein-based medications would be broken down in the stomach before they ever reach the bloodstream. Once BENLYSTA is broken down, it cannot work properly. For this reason, this type of medication is given directly into the bloodstream through an intravenous infusion.

Dr. Mease: In some cases, you may get your infusion at your doctor's office. In other cases, you may get it at a hospital or an infusion center. In general, when you arrive for your treatment, a healthcare professional, such as a nurse, will take you to a room where others may also be receiving infusions.

Dr. Mease: Your infusion with BENLYSTA will take about an hour to complete, with additional preparation time before and observation time after the infusion.

Dr. Mease: Before starting the infusion, the nurse may ask you how you are feeling and will likely check your blood pressure, pulse and temperature. After answering some questions about your medical history, you may receive medications prior to the infusion. For example, you may receive an antihistamine to help reduce your chance of having an allergic reaction. The nurse or other healthcare professional will then insert an IV line into your arm or hand so that you can receive your infusion of BENLYSTA. While they are inserting the IV line, you may feel some pain or discomfort. Also, if you've been given an antihistamine, you may feel tired.

Dr. Mease: Some people like to bring something along to occupy themselves during their infusion, such as a book or crossword puzzle. Of course, you can always close your eyes and get some rest while you are receiving the infusion of BENLYSTA.

Dr. Mease: After the infusion, you may feel some discomfort where you had the IV line inserted. That should go away within a few hours. Depending on how you feel, you may be able to return to your usual activities once the infusion process is over. However, if you were given an antihistamine, you may feel drowsy and may want to go home and rest for a while. If you are drowsy, it is important that you have someone drive you home.

If you don't feel well or have any soreness or tenderness that doesn't go away, contact your healthcare professional.

NOTE: BENLYSTA is an add-on treatment. It is intended to be used together with other lupus medicines.

Other Important Information

In 2 of 3 studies, fewer blacks/African Americans who received BENLYSTA responded to treatment compared to blacks/African Americans who did not receive BENLYSTA. Therefore, caution should be used when considering treatment with BENLYSTA in blacks/African Americans. It is important to discuss with your healthcare professional whether BENLYSTA is right for you. A clinical trial is ongoing to study BENLYSTA specifically in blacks/African Americans with lupus.
