Raghuram (Ram) Selvaraju, Chairman of the Board of Relief, said: "We are pleased that our collaboration partner has reported that it has developed a formulation of aviptadil that it reports is suitable for commercial distribution. Despite the increase in the number of people being fully vaccinated against COVID-19, with emerging variants and disparities in vaccination rates, there remains a major need for effective therapeutic options for patients with respiratory failure. We are excited about the potential that aviptadil holds in helping critical COVID-19 patients and are hopeful that the drug candidate will soon be available to those who remain in need of better treatments."
