Tailored Smoking Cessation Therapy for Smoking Addiction
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores a new method to help people quit smoking through a personalized approach called Metabolism-Informed Smoking Treatment (MIST). The approach matches the right medication with how a person's body processes nicotine, using either Nicotine Replacement Therapy (such as nicotine gum, lozenge, patch, inhaler, or nasal spray) or Varenicline (also known as Chantix or Champix). Participants receive support through phone calls after leaving the hospital to help them stay on track. Daily smokers planning to quit and eligible to use these medications could be a good fit for this trial. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to a potentially groundbreaking treatment.
Do I have to stop taking my current medications for the trial?
The trial information does not specify if you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Studies have shown that the treatments used in the Metabolism-Informed Smoking Treatment (MIST) trial, Nicotine Replacement Therapy (NRT) and varenicline, are generally safe for people.
Research indicates that NRT, which manages cravings and withdrawal symptoms by providing nicotine without smoking, is usually well-tolerated. Minor side effects, such as skin irritation from patches, can occur.
For varenicline, studies found that it significantly aids smoking cessation. Some individuals experience side effects, with nausea and headaches being the most common. Despite these, varenicline is considered safe for many users.
Both treatments have been used in previous studies and are approved for helping people stop smoking. This suggests they are safe options for those considering joining this trial.12345Why do researchers think this study treatment might be promising for smoking addiction?
Researchers are excited about this trial because it explores a more personalized approach to smoking cessation. Unlike the standard care that doesn't consider nicotine metabolism, the MIST (Metabolism-Informed Smoking Treatment) arm tailors medication based on how quickly a person metabolizes nicotine. This means faster metabolizers receive varenicline, while slower metabolizers are given nicotine replacement therapy (NRT). This personalized strategy could potentially enhance the effectiveness of the treatment, offering a more targeted way to help individuals quit smoking.
What evidence suggests that this trial's treatments could be effective for smoking addiction?
Research has shown that customizing smoking treatments based on how quickly a person processes nicotine can be very effective. One study found that people who break down nicotine faster are less likely to quit smoking unless their treatment is adjusted to their metabolism. This is where the Metabolism-Informed Smoking Treatment (MIST), one of the treatment arms in this trial, plays a role. It uses a measure called the Nicotine Metabolite Ratio (NMR) to help choose the best treatment.
In this trial, participants in the MIST arm will receive either Nicotine Replacement Therapy (NRT) or Varenicline, based on their nicotine metabolism. NRT can boost the chances of quitting by 50%. Varenicline, another option in this trial, has shown high effectiveness, with about 44% of people successfully quitting in some studies. When these treatments match a person's nicotine metabolism, they may lead to better success in quitting smoking.23678Who Is on the Research Team?

Are You a Good Fit for This Trial?
This trial is for daily smokers over 18 with a regular healthcare provider, who are willing to try quitting smoking after hospital discharge. They must be able to use nicotine replacement or varenicline, have phone access, a permanent address, and prescription coverage. Those too ill, in hospice care, not cognitively able to participate or already in another smoking study can't join.Inclusion Criteria

Follow-up
Participants are monitored for abstinence and clinical practice implementation at 6 and 12 months
What Are the Treatments Tested in This Trial?
Interventions
- Metabolism Informed Smoking Treatment (Nicotine metabolite ratio (NMR)-based selection of pharmacotherapy)
- Nicotine Replacement Therapy
- Post-discharge automated phone calls (IVR) with option to connect with a tobacco coach
- Varenicline
Trial Overview
The MIST RCT is testing tailored smoking cessation treatments based on how fast individuals metabolize nicotine. Participants will receive either standard Nicotine Replacement Therapy or Varenicline guided by their Nicotine Metabolite Ratio (NMR), along with automated follow-up calls and tobacco coaching.

Experimental Treatment
Active Control
At hospital discharge, participants randomized to the MIST precision care arm will receive a prescription for medication (either varenicline or NRT). Post discharge, participants will receive automated phone calls via TelASK to promote continued engagement. Medication prescriptions will be informed by nicotine metabolism (i.e., NMR result) such that faster metabolizers are prescribed varenicline and slower metabolizers are prescribed NRT.
At hospital discharge, participants randomized to the Usual Care arm will receive a prescription for medication (either varenicline or NRT). Post discharge, participants will receive automated phone calls via TelASK to promote continued engagement. Medication prescription will not be informed by nicotine metabolism.
Nicotine Replacement Therapy is already approved in United States, European Union, Canada, Japan for the following indications:
- Smoking cessation
- Smoking cessation
- Smoking cessation
