About ZYESAMI ™ / VIP in COVID-19
Aviptadil is a synthetic form of vasoactive intestinal polypeptide (VIP), first discovered by the late Prof. Sami Said in 1970, and ZYESAMI ™ is named in his honor. Although primarily concentrated in the lungs, it was first purified from the intestinal tract. VIP binds specifically to the type II alveolar cell (ATII) in the air sac (alveolus) of the lung, where it has been shown to have potent anti-inflammatory / anti-cytokine activity in animal models of distress respiratory, acute lung injury, and inflammation. Most importantly, VIP stimulates ATII cells to make the surfactant that must cover the lining of the lungs so that they exchange oxygen with the blood. The loss of surfactant causes respiratory failure and alveolar collapse, which are hallmarks of COVID-19.

Respiratory failure associated with COVID-19 is caused by selective infection of the ATII cell with the SARS-CoV-2 virus. ATII cells are vulnerable due to their surface receptors (ACE2), which serve as the entry route for the virus. Coronavirus infection of the ATII cell stops surfactant production, triggers the formation of inflammatory cytokines, and causes cell death (cytopathy). VIP has been shown to upregulate surfactant production, block coronavirus replication in the ATII cell, block cytokine synthesis, and prevent virus-induced cell death (cytopathy). Other than ZYESAMI ™, no currently proposed treatment for COVID-19 specifically targets this mechanism of action.
