Press Release - WHO and Unitaid are concerned by Roche's statement yesterday, warning of a global shortage of tocilizumab (brand name Actemra/RoActemra), an IL6 inhibitor WHO recommended in June for use as a treatment for severe COVID-19 cases. Tocilizumab can play a key role in decreasing mortality and reducing need for invasive mechanical ventilation among severely ill patients, when delivered alongside oxygen and corticosteroids.
