What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new treatment called tradipitant for individuals who experience motion sickness during travel. The goal is to determine the safety and effectiveness of tradipitant in reducing symptoms such as nausea and dizziness. Two different doses are being tested to identify which is most effective. Those who have experienced motion sickness in the past, with no other cause for nausea, might find this trial suitable. As a Phase 3 trial, it represents the final step before FDA approval, providing an opportunity to help bring a new treatment closer to availability.

Do I need to stop my current medications to join the trial?

The trial protocol does not specify whether you need to stop taking your current medications.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that tradipitant might help prevent vomiting and treat nausea from motion sickness. Ensuring its safety for people is important. Some studies have tested two doses of tradipitant, 85 mg and 170 mg, focusing on its effects during travel, such as in cars or on boats.

While some research is ongoing, the FDA has placed a partial hold on the drug due to safety concerns that need addressing. This does not mean the drug is unsafe, but more information is needed to confirm its safety for motion sickness.

For those considering joining a trial, these studies aim to find both the benefits and any side effects of the treatment. Participating in a trial contributes to important research that could help answer these safety questions. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for motion sickness?

Researchers are excited about Tradipitant for motion sickness because it offers a new approach compared to traditional treatments like antihistamines and scopolamine. Most current treatments work by blocking histamine or acetylcholine receptors, often causing drowsiness or dry mouth. Tradipitant, on the other hand, targets the neurokinin-1 (NK1) receptors, potentially reducing symptoms without these side effects. This different mechanism of action not only provides an alternative for those who can't tolerate standard treatments but also holds promise for more effective relief.

What evidence suggests that tradipitant might be an effective treatment for motion sickness?

Research has shown that tradipitant effectively treats motion sickness. Studies found that people taking tradipitant vomited less than those who took a placebo, a pill with no active medicine. Other research also supports that tradipitant helps prevent nausea and vomiting during travel. In this trial, participants will receive either a low dose (Dose A) or a high dose (Dose B) of tradipitant, both of which have effectively reduced symptoms of motion sickness. Overall, tradipitant appears to be a promising option for managing motion sickness. ^{1 4 6 7 8}

Are You a Good Fit for This Trial?

This trial is for adults aged 18-75 who have a history of getting motion sickness. It's not suitable for individuals with other nausea-causing conditions, those with a BMI over 40, or anyone allergic to Neurokinin-1 Receptor antagonists.

Transdermal scopolamine significantly reduces motion-induced nausea, achieving a motion sickness incidence of only 16% in a study of 35 susceptible subjects, compared to 32% with oral dimenhydrinate and 59% with placebo.

The transdermal system provides sustained relief for up to 72 hours, offering advantages over oral or intramuscular administration, especially during gastrointestinal distress, and resulting in a 73% protection rate against motion sickness.

Effect of transdermally administered scopolamine in preventing motion sickness. McCauley, ME., Royal, JW., Shaw, JE., et al.[2018]

The transdermal therapeutic system (TTS) for scopolamine provides a constant rate of drug delivery, which helps maintain stable blood levels and reduces the side effects associated with oral dosing.

This new delivery method improves patient compliance and acceptability by allowing for prolonged administration without the need for frequent dosing, making it a safer option for treating motion sickness.

In a study involving 126 adults, the NK1 receptor antagonist tradipitant significantly reduced the incidence of vomiting in participants experiencing motion sickness compared to a placebo, especially in rough sea conditions (tradipitant 15.79% vs. placebo 72.22%).

Tradipitant also led to lower overall motion sickness symptoms, with a mean severity score of 3.19 compared to 4.57 for the placebo group, indicating its potential as an effective treatment for nausea and vomiting associated with motion sickness.

In a study involving 140 subjects, transdermal scopolamine was found to be more effective than oral dimenhydrinate in preventing motion sickness at sea, reducing the incidence of motion sickness to 16.66% compared to 22.22% with dimenhydrinate.

Transdermal scopolamine provided 61.67% protection against motion sickness, significantly outperforming the placebo effect, which only reduced incidence to 43.47%.

In a study involving 20 participants with motion sickness, the transdermal system Scopoderm TTS (scopolamine) was found to be as effective as the oral antiemetic dimenhydrinate during a 1-hour test flight.

Scopoderm TTS offers a significant advantage for long-distance travel, providing effective motion sickness prevention for up to 72 hours, compared to the shorter duration of dimenhydrinate.

Transdermal scopolamine (TTS-scopolamine) and dimenhydrinate were both effective in reducing nausea and vertigo caused by motion sickness in a study of 16 healthy volunteers, with scopolamine showing adequate absorption in all subjects.

Dimenhydrinate was slightly more effective against nausea than one patch of TTS-scopolamine, but both treatments had minimal side effects, although two patches of scopolamine could occasionally cause gait disturbances.
