What is the purpose of this trial?

This trial tests whether nicotine oral pouches (ONPs) can help individuals switch from cigarettes or smokeless tobacco to a less harmful option. ONPs contain nicotine but no tobacco, and researchers consider them safer than smoking. The trial evaluates the effectiveness of these pouches and identifies factors that contribute to their success for those looking to switch. It includes different groups to compare results across various ONP types. Ideal participants smoke at least 5 cigarettes a day or use moist snuff regularly. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group of people.

Do I have to stop taking my current medications for the trial?

The trial protocol does not specify whether you need to stop taking your current medications. However, you must abstain from all tobacco, nicotine, and marijuana use for at least 12 hours before certain study visits.

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

Research has shown that nicotine oral pouches (ONPs) are generally less harmful than traditional cigarettes, cigarillos, and heated tobacco products. ONPs contain nicotine but no tobacco, which may reduce the risk of exposure to harmful substances compared to smoking. However, ONPs are not completely risk-free and may still affect oral health, though the specific impacts remain unclear.

Studies have found that the FDA recognizes ONPs as having a lower risk than regular cigarettes. Still, more research is needed to understand any potential long-term harm they might cause. So far, limited information exists on any serious side effects from ONPs. Prospective clinical trial participants should know that while ONPs may be less risky than cigarettes, they are not entirely without harm. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about nicotine oral pouches for tobacco-related cancer prevention because they offer a potentially safer alternative to traditional tobacco products. Unlike smoking or using standard smokeless tobacco, these pouches provide a controlled delivery of nicotine without harmful combustion or smoke exposure. This novel delivery method could reduce the risk of tobacco-related cancers, as it minimizes exposure to carcinogens typically found in tobacco smoke. Additionally, the use of high free-base nicotine in these pouches might offer better satisfaction for users looking to cut down on traditional tobacco use, making it a promising tool for harm reduction.

What evidence suggests that this trial's treatments could be effective for tobacco-related cancer prevention?

Research has shown that nicotine oral pouches (ONPs) are generally less harmful than traditional cigarettes and other tobacco products. Because ONPs do not contain tobacco, they expose users to fewer harmful chemicals than smoking does. Studies have found that these pouches are well-tolerated in the short term, usually safe to use without causing serious side effects. Experts believe ONPs might even be safer than e-cigarettes, offering a potentially lower-risk option for tobacco users. While the FDA recognizes that ONPs carry a lower risk compared to cigarettes, limited information exists on their long-term safety and effectiveness in helping people switch from smoking to using pouches. This trial will explore various formulations of ONPs, including low and high free-base nicotine versions, to assess their safety and effectiveness in tobacco-related cancer prevention. ^{3 6 7 8 9}

The study analyzed nicotine pouch regulations across 67 countries, revealing significant differences in how these products are classified and regulated, particularly regarding synthetic nicotine.

Only 34 countries have regulations for nicotine pouches, with 23 of those including synthetic nicotine in their policies, highlighting a need for more consistent regulatory frameworks to ensure safety and control over these products.

Tobacco use is a major preventable cause of cancer, linked to 30% of all cancer-related deaths in the U.S., and negatively impacts cancer treatment efficacy, quality of life, and survival outcomes.

The authors recommend that smoking history and status be systematically collected in all oncology clinical trials to better understand its effects on treatment outcomes and to improve patient care.

Nicotine treatment in SCC15 oral squamous cell carcinoma cells increased reactive oxygen species (ROS) levels and promoted cell growth, indicating a potential role in cancer cell proliferation.

At a concentration of 1 µmol/L, nicotine significantly increased cell apoptosis and activated the NF-κB signaling pathway, suggesting that nicotine may influence both growth and death of oral cancer cells through this mechanism.

In a study involving 30 adult smokers, 6-mg oral nicotine pouches (ONPs) delivered more nicotine to the bloodstream at 30 minutes compared to both 3-mg ONPs and cigarettes, suggesting they can be effective for nicotine delivery.

However, neither concentration of ONPs provided as much relief from cravings at 5 minutes as cigarettes did, indicating that while ONPs may be less harmful, they might not satisfy cravings as effectively, which could influence their potential for misuse.

Approximately 46.6% of U.S. adult tobacco users are aware of nicotine pouches, but only 3.0% currently use them, indicating a gap between awareness and actual use.

Younger individuals and those who use smokeless tobacco are more likely to have used nicotine pouches, and having positive beliefs about NPs correlates with increased likelihood of use, highlighting the need for ongoing monitoring of public perceptions and usage trends.

A significant number of patients with head and neck squamous cell carcinoma (HNSCC) continue to smoke after treatment, with 58.4% still smoking at 6 months and 44.9% at 24 months, indicating a persistent challenge in smoking cessation among this group.

The highest likelihood of quitting smoking occurred within the first 6 months post-treatment, suggesting that this period is critical for implementing effective smoking cessation interventions in cancer care.

The Cancer Center Cessation Initiative (C3I) has successfully expanded access to tobacco cessation programs at 52 NCI-designated Cancer Centers, ensuring that cancer patients can receive evidence-based support for quitting tobacco.

Despite the increased availability of these services, patient utilization remains low, prompting the formation of the C3I Implementation Science Working Group to develop strategies that enhance the adoption of tobacco treatment interventions in oncology settings.

A study involving 246 clinicians and 2,146 cancer patients showed that electronic health record (EHR) nudges aimed at clinicians significantly increased tobacco use treatment (TUT) referrals and prescriptions, with TUT penetration rising from 13.5% in usual care to 35.6% with clinician nudges.

The results indicate that while clinician nudges were effective, adding patient nudges did not further enhance TUT engagement, suggesting that targeting clinicians may be the most effective strategy for improving tobacco treatment in oncology settings.

Nicotine pouch use in Great Britain is currently rare, with a prevalence of only 0.26% among adults, but it has doubled from November 2020 to October 2021, indicating a growing interest in these products.

The use of nicotine pouches is significantly more common among men, current smokers, and users of other nicotine products like e-cigarettes and nicotine replacement therapies, suggesting that these pouches may appeal more to those already familiar with nicotine consumption.

Participants in focus groups perceived oral nicotine pouches (ONPs) as having similar or lower risks compared to traditional cigarettes and smokeless tobacco, although they acknowledged potential gastrointestinal and cardiovascular risks.

ONPs were viewed as situational substitutes rather than complete replacements for cigarettes and smokeless tobacco, which could lead to increased overall nicotine use in certain populations, particularly in Appalachia.
