Prurigo Nodularis is a chronic, intensely pruritic dermatological condition characterized by the presence of pruriginous lesions such as papules, nodules or plaques, which may be associated with excoriations and ulcerations.

In September 2018, we initiated our pivotal Phase 2b/3 PRISM (Pruritus Relief thru Itch-Scratch Modulation) clinical trial evaluating the safety and efficacy of Haduvio™ in patients with severe pruritus associated with PN.

The PRISM trial is a randomized, double-blind, placebo-controlled, parallel, two-arm, 14-week treatment study that is evaluating the safety and anti-pruritic efficacy of Haduvio™ 162 mg tablets in 360 patients at more than 60 sites in the United States and Europe.

IPF is a rare, chronic, progressive lung disease, characterized by scarring and thickening of lung tissue; most patients diagnosed with IPF suffer from a dry, non-productive chronic cough that interrupts their daily living and significantly contributes to poor quality of life.

We are conducting a Phase 2 clinical trial of Haduvio™ for chronic cough in patients with IPF. The Phase 2 trial is a randomized, double-blind, placebo controlled, two-treatment, two-period, crossover study designed to evaluate the efficacy, safety, tolerability and dosing of Haduvio™ for chronic cough in up to 56 patients with IPF in the United Kingdom.

A common complication of chronic cholestatic liver diseases such as primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC); patients develop severe whole-body itch, an intense, intractable, debilitating condition that significantly disrupts patients’ daily activities and sleep, and consequently impairs their quality of life.

A Phase 1b open label study is complete to determine the safety and pharmacokinetics of Haduvio™ in patients with moderate to severe chronic liver disease.

A common, disruptive pruritic condition principally experienced by an estimated 70% of patients undergoing hemodialysis; causes significant impairment in patients’ quality of life and increased mortality.

We are not actively developing Haduvio™ for uremic pruritus at this time based on our evaluation of the market dynamics, but may consider resuming development in the future.

Involuntary movements that negatively impact patients’ lives; it is estimated that motor complications resulting from levodopa therapy affect about 400,000 patients with Parkinson’s disease in the United States, with dyskinesia occurring in approximately 150,000 patients.

Subject to discussions with the FDA and the submission of an IND for this indication, we intend to initiate a Phase 2 trial of Haduvio™ to evaluate the effect of Haduvio™ on LID in patients with Parkinson’s disease.
