Announcement
Roivant announced that Japan's Ministry of Health, Labour and Welfare (MHLW) has granted orphan drug designation (ODD) to mosliciguat, a novel, once-daily, inhaled soluble guanylate cyclase (sGC) activator, currently being studied for the treatment of Pulmonary Hypertension associated with Interstitial Lung Disease (PH-ILD), which is a progressive and life-threatening condition with significant unmet medical need.
AI Summary
Roivant announced that Japan’s Ministry of Health, Labour and Welfare has granted orphan drug designation (ODD) to mosliciguat, a novel, once-daily, inhaled soluble guanylate cyclase activator. Mosliciguat is being studied for Pulmonary Hypertension associated with Interstitial Lung Disease (PH-ILD), a progressive, life-threatening condition with no approved treatments.
The ODD status, based on the recommendation of Japan’s Pharmaceuticals and Medical Devices Agency, provides key regulatory incentives such as priority consultation, reduced fees, and up to ten years of market exclusivity if approved. Roivant’s CEO Drew Fromkin said this designation recognizes the significant unmet need for PH-ILD patients and underscores the company’s commitment to advancing mosliciguat in Japan.
Mosliciguat is now in a global Phase 2 trial called PHocus, which will enroll about 120 adults with PH-ILD. Details of the study design will be presented in a poster at the European Respiratory Society International Congress on September 28, 2025.

Announcement
Pulmovant, a Roivant company announced the presentation of data from the proof-of-concept Phase 1b ATMOS1 study during the ERS Congress in Vienna, Austria.
AI Summary
Pulmovant, a Roivant company, recently presented data from its proof-of-concept Phase 1b ATMOS1 study during the European Respiratory Society (ERS) Congress in Vienna, Austria. The study evaluated mosliciguat, an innovative, first-in-class inhaled soluble Guanylate Cyclase (sGC) activator specifically designed to target the lungs in patients with pulmonary hypertension (PH).
In this trial, 38 patients received a single dose of mosliciguat via a dry powder inhaler, resulting in a sustained, clinically meaningful reduction of pulmonary vascular resistance (PVR) by up to 38%—one of the most significant drops seen in PH studies. The once-daily dosing was well tolerated, with few treatment-emergent adverse events reported. These promising findings have set the stage for further research, including an upcoming global Phase 2 study focused on patients with PH associated with interstitial lung disease (PH-ILD).
