Detailed Narrative
IMVT-1402 DTRA Study Highlights
The preliminary open-label data from the IMVT-1402 DTRA study in heavily refractory rheumatoid arthritis patients showed unexpectedly strong responses. Patients had failed at least two advanced lines of therapy, including TNF and JAK inhibitors, and had strict autoantibody positivity criteria. The study design included a 16-week open-label active treatment period followed by a 12-week randomized withdrawal.
IMVT-1402 Efficacy and Safety
In the DTRA study, 73% of patients achieved ACR20 responses, over 50% achieved ACR50, and over 33% achieved ACR70. These deep responses are considered clinically meaningful, especially given the lack of significant placebo response at ACR50/70 levels. The efficacy was preserved in the JAK-experienced subset (65% of patients). IMVT-1402 was safe and well-tolerated, with no new safety signals identified across hundreds of patients dosed, including no impact on LDL.
Mosliciguat (mosli) for PH-ILD
Mosli is an inhaled sGC activator delivered directly to the lungs, aiming to address both pulmonary vascular and lung parenchymal diseases in PH-ILD. Phase I data showed a mean PVR reduction of 38% and a mean peak PVR reduction of approximately 38% with a single dose, placing it among the highest reductions seen in the PH treatment space. It was well-tolerated with limited systemic side effects and no significant cough.
Mosliciguat Phase II FOCUS Study Design
The Phase II FOCUS study is a blinded, placebo-controlled, randomized trial targeting 120-135 patients with PH-ILD, carefully selected based on Seventh World Symposium guidelines. The primary endpoint is change from baseline PVR at 16 weeks. The study is not powered for a p-value on 6-minute walk, but will look for trends. Enrollment was completed quickly, with 135 patients, and over 95% reached the maximum 4mg dose.
Brepocitinib Program Updates
Brepocitinib received Breakthrough Therapy Designation for cutaneous sarcoidosis, with a Phase III study expected to begin this year. The LPP study is actively enrolling. Commercial preparations for the dermatomyositis launch by the end of September are underway, including payer engagement, physician community work, and specialty pharmacy partnerships. The Phase III data for dermatomyositis was published in NEJM.
Financial Strength and Capital Allocation
Roivant maintains a strong financial position with $4.3 billion in cash and cash equivalents as of March 31, 2026, prior to the $2.25 billion Moderna settlement ($950 million upfront in July). The company continues to execute share repurchases and has no debt. R&D spend has increased with program scope.
