WASHINGTON, Aug. 18, 2020 /PRNewswire/ -- Vanda Pharmaceuticals Inc. (Vanda) (Nasdaq: VNDA) today reported that interim analysis showed tradipitant may accelerate clinical improvement in SARS-CoV-2 (COVID-19) pneumonia in the ODYSSEY study.
The interim analysis of the ODYSSEY study demonstrated that hospitalized patients with COVID-19 pneumonia improved sooner when treated with tradipitant as compared to placebo. This finding was based on a preliminary analysis of the first 60 patients enrolled in the ODYSSEY study of tradipitant in COVID-19 pneumonia. ODYSSEY is an ongoing Phase III double-blind placebo-controlled trial investigating the efficacy and safety of tradipitant, a neurokinin-1 receptor (NK-1R) antagonist, in the treatment of neurogenic inflammation of the lung secondary to SARS-CoV-2 (COVID-19) infection, which was initiated in April 2020. The study is expected to enroll 300 patients, and as of July 15, 2020, 60 patients had enrolled and completed the study. Because this is the first study of tradipitant for this indication and given the increased rate of mortality seen with COVID-19 pneumonia, an interim analysis was planned to better assess the efficacy and safety of tradipitant in this population of COVID-19 patients.
In the ODYSSEY study, clinical status was assessed on a 7 point scale ranging from death, to mechanical ventilation, various levels of oxygen requirements, to hospital discharge. Clinical improvement was defined as at least a 2 point improvement in the 7 point ordinal scale.
This early analysis suggests that tradipitant may act by accelerating the time to clinical improvement for patients with severe COVID-19 pneumonia. If confirmed, this effect may be of significant clinical benefit for patients as well as for public health by decreasing the amount of resources employed in the treatment of patients with COVID-19 pneumonia. Although preliminary, the interim results from this randomized controlled study of tradipitant in COVID-19 pneumonia are encouraging. A larger sample size would be required to definitively determine whether tradipitant offers a therapeutic benefit in hospitalized patients with COVID-19 pneumonia by accelerating time to clinical improvement. The results from this interim analysis will be submitted for publication in a peer reviewed journal.
The hypothesized mechanism of action of tradipitant as an anti-inflammatory agent in COVID-19 pneumonia potentially would be complementary to antiviral treatments. Ongoing efforts in the development of COVID-19 therapeutics require coordination and cooperation between parties if they are to result in the discovery of useful therapeutics. Vanda looks forward to collaborating with U.S. government agencies and hospitals across the country to confirm these findings expediently. If these results are confirmed, tradipitant could become part of the standard of care, either alone or in combination with antivirals, for patients with COVID-19 pneumonia.
"These results, albeit preliminary, are exciting, offering the promise of a significant contribution in the treatment of COVID-19 and the prospect of making tradipitant part of the standard of care in accelerating recovery for patients with COVID-19 pneumonia," said Mihael H. Polymeropoulos, M.D., President and CEO of Vanda.
Vanda has scaled up the commercial manufacturing of tradipitant and significant supplies are expected to be available in the coming months. As the results today may suggest that tradipitant's effects in accelerating recovery may not be restricted to just COVID-19 pneumonia, Vanda also plans to evaluate a clinical program to assess the efficacy of tradipitant in the treatment of seasonal influenza pneumonia.
