Fostemsavir is the phosphonooxymethyl prodrug of temsavir, a novel HIV-1 attachment inhibitor. It binds to and inhibits the activity of gp120, a subunit within the HIV-1 gp160 envelope glycoprotein that facilitates the attachment of HIV-1 to host cell CD4 receptors - in doing so, temsavir prevents the first step in the HIV-1 viral lifecycle. The discovery of gp120 as a potential target of interest in the treatment of HIV-1 infection is relatively recent, and was born out of a desire to find alternative target proteins (i.e. mechanistically orthogonal therapies) for the treatment of HIV-1 patients with resistant infections. Fostemavir is the first attachment inhibitor to receive FDA approval, granted in July 2020 for use in combination with other antiretrovirals in highly treatment-experienced patients with multidrug-resistant HIV-1 infection whom are failing their current therapy.[L14867,L
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]
