Roivant Unveils New Pipeline Program Mosliciguat, A Potential First-In-Class and Best-In-Category Inhaled Once-Daily Soluble Guanylate Cyclase (sGC) Activator
Roivant (Nasdaq: ROIV) unveiled mosliciguat, a potential first-in-class inhaled once-daily soluble Guanylate Cyclase (sGC) activator for pulmonary hypertension associated with interstitial lung disease (PH-ILD). The Phase 1b ATMOS study showed clinically meaningful reductions in pulmonary vascular resistance (PVR) of up to ~38% in PH patients. Mosliciguat was generally well-tolerated with low rates of adverse events.
The global Phase 2 'PHocus' study in ~120 PH-ILD patients is set to begin soon. PH-ILD affects ~200,000 patients in the U.S. and Europe, with treatment options. Roivant acquired worldwide rights to mosliciguat from Bayer for an upfront payment of ~$14.0 million, with potential additional payments of up to $280 million and tiered royalties.

- Mosliciguat showed up to 38% reduction in pulmonary vascular resistance in Phase 1b study
- Once-daily dosing via dry powder inhaler, improving convenience for patients
- Generally well-tolerated with low rates of treatment-emergent adverse events
- Targeting PH-ILD, a market of ~200,000 patients in the U.S. and Europe with treatment options
- Global Phase 2 study in ~120 PH-ILD patients to begin imminently
- Upfront payment of ~$14.0 million to Bayer for mosliciguat rights
- Potential additional payments of up to $280 million in milestones
- Tiered high-single digit sales-based royalties to be paid to Bayer
The Phase 1b ATMOS study results for mosliciguat are highly promising. The
The sGC activator mechanism of mosliciguat is particularly intriguing. Unlike sGC stimulators, it functions independently of heme and NO, potentially maintaining efficacy in the oxidative environments typical of PH. This could translate to broader efficacy across PH subtypes, addressing a critical unmet need in PH-ILD patients.
The upcoming Phase 2 PHocus study will be important in validating these early results in the target PH-ILD population. If successful, mosliciguat could significantly impact the
Roivant's unveiling of mosliciguat represents a significant potential value driver for the company. The PH-ILD market, with ~200,000 patients in the U.S. and Europe, presents a substantial commercial opportunity. Given the treatment options and high unmet need, a successful therapy could rapidly capture market share.
The licensing deal with Bayer appears favorably structured for Roivant. The
Investors should note that while early data is promising, significant clinical and regulatory hurdles remain. The upcoming Phase 2 trial will be a critical inflection point. Success could drive substantial value creation, while failure would likely impact Roivant's stock negatively. The company's diversified pipeline helps mitigate this risk.
Mosliciguat's potential as a first-in-class and best-in-category therapy for PH-ILD is significant. The once-daily dosing via dry powder inhaler addresses a key patient need, potentially improving adherence and quality of life compared to existing therapies requiring multiple daily doses or nebulizers.
The larger prevalence of PH-ILD compared to PAH presents a substantial market opportunity. With an estimated 200,000 patients in the U.S. and Europe and treatment options, mosliciguat could rapidly gain market share if approved.
However, market penetration will depend on the therapy's long-term safety profile and its ability to demonstrate meaningful clinical benefits in the Phase 2 and potential Phase 3 trials. The competitive landscape should also be monitored, as success could attract other players to this underserved market. Pricing strategy will be crucial, balancing market access with profitability in this potentially lucrative indication.

BASEL, Switzerland and LONDON and NEW YORK, Sept. 10, 2024 (GLOBE NEWSWIRE) -- Roivant (Nasdaq: ROIV) today announced its previously undisclosed pipeline program mosliciguat, a potential first-in-class, inhaled, once-daily sGC activator with targeted delivery to the lungs via dry powder inhaler, at Pulmovant. Pulmovant presented data from the proof-of-concept Phase 1b ATMOS study during the ERS Congress in Vienna, Austria.
“We believe mosliciguat can transform the lives of patients living with pulmonary hypertension, and I am excited to announce this potential first-in-class and best-in-category therapy. Mosliciguat has the incredibly rare advantage of potential differentiation across three separate key areas - efficacy, safety, and convenience in administration. We are impressed with the data generated so far, particularly the PVR results, and we believe its differentiated mechanism as an sGC activator can have maximal impact on PH-ILD patients, a large population with severe disease, high morbidity and mortality, and few treatment options,” said Matt Gline, Roivant’s Chief Executive Officer. “Along with the positive Graves’ data announcement at Immunovant yesterday, we feel incredibly fortunate to announce another exciting clinical update this week. As promised, we are continuing to expand our existing pipeline and remain laser-focused on clinical execution, with a number of important study readouts and milestones expected in the coming months.”
Mosliciguat has been extensively characterized across a robust Phase 1 program with 170 participants dosed to date, including in the ATMOS study, and based on data from these studies has the potential to show differentiation in efficacy, safety and convenience. Mosliciguat’s target, sGC, is a key enzyme in the nitric oxide (NO) / cyclic guanosine monophosphate (cGMP) signaling pathway that catalyzes cGMP production leading to increased vasodilation, reduced inflammation and apoptosis, reverse vascular remodeling and anti-fibrotic effects. Unlike sGC stimulators which require reduced heme and NO to exert their effect on sGC, mosliciguat is an sGC activator that works independently of heme and NO. This also allows mosliciguat to potentially retain efficacy in highly oxidative environments typical of PH, where stimulators are expected to lose efficacy given heme is oxidized or removed and NO levels are depleted.
ATMOS was a non-randomized, open-label, dose escalation, proof-of-concept Phase 1b trial that assessed the efficacy, safety, tolerability, and pharmacokinetics of mosliciguat following single dose inhaled administration in participants aged between 18 and 80 years with World Health Organization (WHO) Group 1 PH (pulmonary arterial hypertension (PAH)) or Group 4 PH (chronic thromboembolic pulmonary hypertension (CTEPH)). Overall, 38 patients received mosliciguat in this study. In the per-protocol set of patients (N=20), mosliciguat 1.0, 2.0 and 4.0 mg doses led to mean-max peak reductions in PVR from baseline of -
Overall, in its Phase 1 development program in 170 healthy volunteers and PH patients, mosliciguat has shown a favorable safety profile, dose-dependent increases in cGMP and a 40-hour half-life supporting convenient dosing. Mosliciguat is unique among inhaled PH therapies, requiring just one puff once per day to deliver its potential best-in-category PVR reductions – all currently approved therapies require multiple puffs, multiple times per day. Mosliciguat is formulated for delivery via DPI, providing greater convenience to patients compared to nebulizers required for many existing inhaled PH therapies. Direct delivery to the lungs also minimizes risk of serious adverse effects seen with systemic vasodilators, such as worsening of oxygenation status. In addition to greater efficacy as evidenced by PVR in ATMOS, a generally favorable safety profile and ease of administration support the potential differentiation for mosliciguat.
Pulmovant will advance the clinical program to assess mosliciguat in its global Phase 2 PHocus study in patients with PH-ILD, a subgroup of Group 3 PH. Approximately 120 patients will be enrolled in the study, which will start imminently. An estimated 200,000 patients across the U.S. and Europe are living with PH-ILD and have limited or no approved treatment options. The PH-ILD prevalence is meaningfully greater than that of PAH, representing an attractive commercial opportunity with limited competition and high unmet patient need.
Roivant created Pulmovant, a wholly-owned Roivant subsidiary, to in-license from Bayer exclusive worldwide rights to develop and commercialize mosliciguat. Bayer received an upfront cash payment of ~
