What is this trial about?

A plain-language summary of the goals, design and what participants do

This clinical trial is focused on helping people who use e-cigarettes and want to quit. The study will test a treatment called Nicotine Freshmint Mouthspray, which is a spray used in the mouth that contains nicotine. The trial will compare this spray to a similar spray that looks the same but does not contain nicotine, known as a placebo. The main goal of the study is to see how effective the Nicotine Freshmint Mouthspray is in helping people stop using e-cigarettes.

Participants in the study will be randomly assigned to use either the Nicotine Freshmint Mouthspray or the placebo. The study will last for several weeks, during which participants will visit the clinic at different times to check their progress. These visits will help researchers understand how well the spray works and if there are any side effects. Participants will be asked to report if they have stopped using e-cigarettes and if they have any cravings or withdrawal symptoms.

The study will also monitor the safety of the Nicotine Freshmint Mouthspray by collecting information on any adverse events reported by participants. This information will help determine if the spray is safe to use. The trial aims to provide valuable insights into whether the Nicotine Freshmint Mouthspray can be an effective aid for people looking to quit e-cigarettes.

The research process

The trial runs in 7 steps – from screening to follow-up. Each step says what happens and what the team monitors.

Step 1
Initial visit
Upon joining the study, participants will attend an initial visit. During this visit, participants will be informed about the study details and will sign a consent form to confirm their willingness to participate.
Participants will undergo an assessment to ensure they meet the study's eligibility criteria, which includes being a healthy individual over 18 years old, having a history of daily nicotine intake from vaping for at least 3 months, and a strong motivation to quit nicotine.
Step 2
Randomization
Participants will be randomly assigned to one of two groups: one group will receive the Nicotine Freshmint Mouthspray, and the other group will receive a placebo mint mouthspray that looks the same but does not contain nicotine.
This process is double-blind, meaning neither the participants nor the researchers will know which group the participants are in.
Step 3
Treatment phase
Participants will use the assigned mouthspray as directed. The mouthspray is administered oromucosally, which means it is sprayed into the mouth.
The dosage and frequency of use will be explained during the initial visit, and participants are expected to follow these instructions throughout the study.
Step 4
Follow-up visits
Participants will attend regular follow-up visits at weeks 2, 4, 6, 12, 26, 30, and 52. During these visits, participants will report their progress and any side effects they may experience.
The study will monitor participants' abstinence from e-cigarettes and verify this through various tests, including checking for nicotine by-products in the body.
Step 5
Daily diary
Participants will be required to keep a daily electronic diary (eDiary) to record their urge to vape, any e-cigarette use, and the number of mouthspray doses taken.
This diary helps track progress and any withdrawal symptoms experienced during the study.
Step 6
Safety monitoring
Throughout the study, participants' safety will be closely monitored. Any adverse events or side effects should be reported immediately.
The study team will evaluate and analyze these reports to ensure participant safety.
Step 7
End of study
The study is expected to conclude by February 2026. Participants will have a final visit to assess their overall progress and any long-term effects of the treatment.
Participants will receive information on further support for maintaining nicotine abstinence after the study ends.

Investigated drugs

Nicotine Freshmint Mouthspray is a type of nicotine replacement therapy designed to help people who want to quit using e-cigarettes. It comes in the form of a mouth spray with a fresh mint flavor. The spray delivers a small amount of nicotine into the mouth, which is absorbed through the lining of the mouth. This helps to reduce cravings and withdrawal symptoms that people often experience when they stop using e-cigarettes. The goal of using this mouth spray is to make it easier for people to quit e-cigarettes by providing a controlled amount of nicotine without the harmful effects of smoking or vaping.

What is already known about the treatment

Nicotine Freshmint Mouthspray – This medication is administered as a mouth spray and is designed to help people who use e-cigarettes to quit vaping. It is currently being studied in clinical trials to assess its effectiveness and safety compared to a placebo. The main therapeutic use of this spray is to support vaping cessation by providing a controlled dose of nicotine to reduce withdrawal symptoms. At the molecular level, it works by delivering nicotine, which binds to receptors in the brain, helping to reduce cravings and withdrawal effects. It is classified pharmacologically as a nicotine replacement therapy.

Investigated diseases

Nicotine Dependence – Nicotine dependence is a condition characterized by an addiction to nicotine, a chemical found in tobacco products, including e-cigarettes. It develops as nicotine alters brain chemistry, leading to cravings and withdrawal symptoms when not consumed. Over time, individuals may require increasing amounts of nicotine to achieve the same effects, reinforcing the cycle of addiction. The progression of nicotine dependence can lead to habitual use, making it challenging to quit. Withdrawal symptoms can include irritability, anxiety, difficulty concentrating, and increased appetite. The condition often requires behavioral changes and support to overcome.
