Tofacitinib is an inhibitor of Janus kinases, a group of intracellular enzymes involved in signalling pathways that affect hematopoiesis and immune cell function. It is approved by the FDA for treatment of moderate to severe rheumatoid arthritis that responds inadequately to methotrexate or in those who are intolerant to methotrexate. Besides rheumatoid arthritis, tofacitinib has also been studied in clinical trials for the prevention of organ transplant rejection, and is currently under investigation for the treatment of psoriasis. Known adverse effects include nausea and headache as well as more serious immunologic and hematological adverse effects. Tofacitinib is marketed under the brand name Xeljanz by Pfizer.
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]
