Bristol-Myers Squibb
announced that the FDA has approved Nulojix or belatecept for the prevention of acute rejection in adult patients who underwent kidney transplant. The medication is approved under a condition that it is to be used with other immunosuppressants specifically basiliximab, mycophenolate, and corticosteroid.
Nulojix is a T-cell co-stimulation blocker. If you are not familiar with immunology, T-cell plays an important role in our immune system. It has key role in the defense mechanism. In patients undergoing transplantation, to prevent the body from rejecting the organ, often time, we have to give immunosuppressant to suppress the immune system (make it weaker so that it can’t form an attack against the transplant organ). Organ rejection has not been a common issue since the emerging of the immunosuppressant.
The approval came from the results of the two open-label, randomized, multicenter, controlled phase 3 studies in over 1,200 patients. The studies evaluating two dose regimens of Nulojix in addition to cyclosporine showed that the regimen was safe and effective for the prevention of acute organ rejection.
Common adverse reactions observed in patients in the trials were: anemia, constipation, kidney or bladder infection, and swollen legs, ankles, or feet. Patients taking Nulojix is advised to stay away frm the sun due to an increase risk of skin cancer. Patients are also advised to not take any live vaccines due to risk of infections.
Strength and formulations: 250 mg Lyophilized powder per vial. Each vial is accompanied with a 12 mL syringe.
