Frequently asked questions about Gimsilumab

What is gimsilumab?

Gimsilumab is an investigational monoclonal antibody developed by Roivant Sciences Ltd. (ticker ROIV) for the treatment of COVID-19. It was studied in patients with lung injury or acute respiratory distress syndrome secondary to COVID-19. It is a Phase 2 candidate and has not been approved by the FDA.

What is gimsilumab used for in COVID-19?

Gimsilumab was studied for lung injury or acute respiratory distress syndrome secondary to COVID-19. The Phase 2 BREATHE trial enrolled 227 participants aged 18 years and older in the United States. Gimsilumab remains investigational and is not an approved treatment for COVID-19.

What does gimsilumab target?

Gimsilumab targets CSF2, also known as granulocyte-macrophage colony-stimulating factor (GM-CSF). It is an inhibitor of this target, meaning it is designed to block CSF2 signaling. This mechanism was the basis for studying gimsilumab in inflammatory lung injury associated with COVID-19.

Who is developing gimsilumab?

Gimsilumab is being developed by Roivant Sciences Ltd., which trades under the ticker ROIV. Roivant sponsored the Phase 2 BREATHE study of gimsilumab in COVID-19 patients with lung injury or acute respiratory distress syndrome.

What phase is gimsilumab in?

Gimsilumab is in Phase 2 development. Its only registered trial, the BREATHE study, was a Phase 2 trial that has been completed. Gimsilumab is investigational and has not been approved by the FDA for any indication.

What clinical trials is gimsilumab in?

Gimsilumab was evaluated in one clinical trial, NCT04351243, also called the BREATHE study. This completed Phase 2 trial tested gimsilumab in 227 participants with lung injury or acute respiratory distress syndrome secondary to COVID-19. It was randomized, double-blind, and placebo-controlled, and enrolled patients in the United States.
