Metabolism Informed Smoking Treatment: The MIST RCT

Phase 3
Completed
Conditions
Smoking
Interventions
Behavioral: Post-discharge automated phone calls (IVR) with option to connect with a tobacco coach.
Other: Metabolism Informed Smoking Treatment (Nicotine metabolite ratio (NMR)-based selection of pharmacotherapy)
Registration Number
NCT04590404
Lead Sponsor
Vanderbilt-Ingram Cancer Center
Brief Summary

This phase 3 randomized controlled trial will test Metabolism-Informed Smoking Treatment (MIST), a precision approach to smoking treatment that biologically tailors medication selection to nicotine metabolism.

Detailed Description

This is a randomized controlled trial to compare effects of MIST versus usual care (UC) interventions on the outcomes below.

Objectives:

* Abstinence as defined by biochemically-verified self-reported 7-day point prevalence abstinence at 6 m (1° study outcome) and 12 m (2° outcome).

* Clinical practice implementation as measured by participant self-reported medication adherence at months 1 and 3, self-reported receipt of prescription for smoking cessation medication after hospital discharge, and whether the prescription was tailored to the NMR result.

Exploratory Objective:

- Longitudinal assessment of health care utilization visits (ER and hospitalization) for 12 months following hospital discharge.

GroupInterventionDescription
MIST (Metabolism-Informed Smoking Treatment)Post-discharge automated phone calls (IVR) with option to connect with a tobacco coach.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.
MIST (Metabolism-Informed Smoking Treatment)Metabolism Informed Smoking Treatment (Nicotine metabolite ratio (NMR)-based selection of pharmacotherapy)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.
Usual CarePost-discharge automated phone calls (IVR) with option to connect with a tobacco coach.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.
Usual CareNicotine Replacement TherapyAt 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.
MIST (Metabolism-Informed Smoking Treatment)Nicotine Replacement TherapyAt 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.
MIST (Metabolism-Informed Smoking Treatment)VareniclineAt 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.
Usual CareVareniclineAt 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.
