Belatacept is a soluble fusion protein, which links the extracellular domain of human cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) to the modified Fc (hinge, CH2, and CH3 domains) portion of human immunoglobulin G1 (IgG1). Structurally, abatacept is a glycosylated fusion protein with a MALDI-MS molecular weight of 92,300 Da and it is a homodimer of two homologous polypeptide chains of 357 amino acids each. It is produced through recombinant DNA technology in mammalian CHO cells. The drug has activity as a selective co-stimulation modulator with inhibitory activity on T lymphocytes. It is approved for the treatment of rheumatoid arthritis. Belatacept selectively blocks the process of T-cell activation. It was developed by Bristol-Myers-Squibb. Belatacept is only 2 amino acids different
Ozanimod is a once-daily sphingosine 1-phosphate receptor modulator for the treatment of relapsing Multiple Sclerosis (MS) and inflammatory bowel disease. It was developed by Celgene (now acquired by Bristol-Myers Squibb) and was approved by the FDA on March 26, 2020.[L12573,L12582] The US approval was followed by the approval in Canada on October 2, 2020. In November 2021, ozanimod was also approved by the European Commission for the treatment of adults with relapsing remitting multiple sclerosis.[L39377,L39382] MS is a devastating inflammatory disease that often progresses and causes severe neurological, physical, and cognitive effects. Inflammatory bowel disease also a chronic inflammatory condition and can cause persistent abdominal pain, diarrhea, bloody stools, and vomiting. In clinical trials, Ozanimod has been shown to be well-tolerated and has resulted in a higher decrease in the rate of MS relapses than with intramuscular [interferon beta-1a], a current standard in MS therapy. Studies involving patients with inflammatory bowel disease have also shown promising results.[A189318,A189342]
