Frequently asked questions about Mosliciguat

What is mosliciguat?

Mosliciguat is an inhaled small molecule being developed by Roivant Sciences Ltd. (ticker ROIV) for pulmonary hypertension. It is an investigational therapy in Phase 3 clinical development and has received an orphan drug designation from the FDA. It is also referred to as inhaled mosliciguat.

What is mosliciguat used for in pulmonary hypertension?

Mosliciguat is being studied for pulmonary hypertension, with the clinical program focused on pulmonary hypertension associated with interstitial lung disease, known as PH-ILD. The trials enroll adults with pulmonary hypertension, interstitial lung disease, and related vascular and cardiovascular conditions.

Who makes mosliciguat?

Mosliciguat is developed by Roivant Sciences Ltd., which trades under the ticker ROIV. The company is running the clinical program for the inhaled small molecule across pulmonary hypertension associated with interstitial lung disease.

What phase is mosliciguat in?

Mosliciguat is in Phase 3 clinical development. It is investigational and has not been approved by the FDA. The Phase 3 program includes the PHrontier trial, and earlier Phase 2 studies of the drug in PH-ILD are also part of the development effort.

What clinical trials is mosliciguat in?

Mosliciguat is being evaluated in three trials. The Phase 3 PHrontier trial (NCT07816185) is recruiting 376 patients. A Phase 2 combination study with inhaled treprostinil (NCT07333183) is recruiting 20 patients, and a Phase 2 PH-ILD study (NCT06635850) is active but not recruiting 135 patients.

Is mosliciguat the same as inhaled mosliciguat?

Yes, inhaled mosliciguat is another name for mosliciguat. Both refer to the same investigational small molecule developed by Roivant Sciences Ltd. for pulmonary hypertension, delivered by inhalation and studied in pulmonary hypertension associated with interstitial lung disease.
