In the Motion Syros study, 365 participants embarked on boat trips under varied sea conditions and received tradipitant 170 mg, tradipitant 85 mg, or placebo.
Study participants had a prior history of motion sickness and were distributed across thirty-four boat trips between November 2021-April 2023.
170 mg and 85 mg tradipitant doses were superior to placebo in preventing vomiting, with only 18.3% and 19.5% of participants experiencing vomiting on tradipitant 170 mg and 85 mg, respectively, compared to 44.3% of participants on placebo.
The FDA has not approved a new medication for motion sickness in over forty years since scopolamine, a transdermal patch placed behind the ear, was approved in 1979.
Price Action: VNDA shares are down 1.39% at $6.03 on the last check Thursday.
