Vanda Pharmaceuticals Reports Results from a Phase III study of Tradipitant in Motion Sickness
The Motion Syros study was a multicenter, randomized, double-blind, placebo-controlled study where 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 that took place between November 2021 and April 2023. Sea conditions and participant evaluation of the symptoms of motion sickness were recorded for each trip. The primary endpoint of the study was the effect of tradipitant on vomiting induced by motion sickness.
Both 170 mg and 85 mg tradipitant doses were shown to be 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, as compared to 44.3% of participants on placebo (p < 0.0001 for both).
Motion sickness remains an unmet need as various pharmacological and non-pharmacological interventions suffer from low efficacy, substantial side effects, or both. The
Vanda plans to continue the motion sickness clinical program and pursue FDA approval upon completion of additional efficacy and safety studies.

Motion sickness is a disorder characterized by a constellation of symptoms, with nausea and vomiting being the primary ones1. Motion sickness has plagued travelers for thousands of years, as evidenced by the ancient Greek physician Hippocrates who wrote "sailing on the sea proves motion disorders the body"1. Historians theorize that motion sickness may have changed the fate of civilization on several occasions, notably the defeat of the Spanish Armada by the English in 1588 and the negative effects on Napoleon's camel corps during the Egyptian campaign in 17982.
It is believed that a discrepancy between actual body position and perceived body position triggers the maladaptive response of motion sickness3. Approximately 30% of the general population is reported to suffer from motion sickness under ordinary travel conditions that include sea, air and land travel4.
According to IQVIA data, approximately two to three million doses of Dramamine, a common motion sickness remedy, are purchased monthly in the
Motion sickness is one of the most prevalent episodic disorders in the world, whose prevalence has dramatically increased with world population mobility over the last 100 years.
