NCT04553263

Brief Summary

The purpose of this study is to assess the relationship between bupropion, stimulant use and relapse, ADHD (Attention Deficit Hyperactivity Disorder), and measures of mood, drug craving, and inhibitory control in individuals enrolled in inpatient treatment for stimulant-use disorder with and without ADHD. The experimenters hypothesize that Bupropion and Contrave (Bupropion/Naltrexone) will increase inhibitory control and decrease drug craving and depressive symptoms in recently abstinent stimulant users in inpatient treatment with effects greater than those seen in recently abstinent stimulant users completing inpatient treatment as usual. An additional hypothesis is that relapse rates after leaving inpatient treatment in the group receiving bupropion will be lower than those of the group completing inpatient treatment as usual. The study design consists of four assessments of drug craving, inhibitory control, impulsive choice, and mood (depression and anxiety). The timepoints for these assessments include: A. baseline after entering treatment B. 2 weeks after starting drug C. 8 weeks after starting drug, and D. 1 month after leaving treatment. Following eligibility screening, 60 stimulant users will be enrolled in one of 3 groups. Group 1 Bupropion Active Group: 20 subjects will receive bupropion for 8 weeks during inpatient treatment. Group 2 Contrave Active Group: 20 subjects will receive Contrave for 8 weeks during inpatient treatment. Group 3 Control Group: 20 subjects enrolled in inpatient treatment will complete treatment as usual as well as the four assessments (A-D) described above but will not receive drug (convenience control). Half of the subjects in each group will be diagnosed with ADHD and half will not, for a total of 10 subjects per group with ADHD.

Study Arms (3)

Contrave

EXPERIMENTAL

Participants will receive daily weight loss medication, Contrave, at a dose of 360 mg (Naltrexone HCl 32mg, Bupropion HCl 360mg). The dose will be titrated: 8 mg/90 mg on Week 1, 16 mg/180 mg on Week 2, 24 mg/270 mg on Week 3 and 32 mg/360 mg on Week 4. Dosing will continue for a total of 4 weeks during inpatient treatment, and thereafter for another month, with compliance monitored by smartphone.

Drug: Contrave 8Mg-90Mg Extended-Release Tablet

Bupropion

EXPERIMENTAL

Participants will receive daily extended-release oral bupropion (Wellbutrin XL) at a dose of 450 mg. The dose will be titrated: 150 mg on Days 1 and 2, 300 mg on Days 3 and 4, and 450 mg on Day 5. Dosing will continue for a total of 4 weeks during inpatient treatment, and thereafter for another month, with compliance monitored by smartphone. A reduction to 300 mg will permitted to alleviate medication-related adverse effects if they occur.

Drug: Bupropion

Treatment As Usual

NO INTERVENTION

Participants will complete inpatient treatment as usual and will not receive any medication. This arm serves as a TAU control to compare outcomes versus Bupropion and Contrave arms.

Interventions

Naltrexone HCl/Bupropion HCl is an FDA-approved weight-loss medication with efficacy via the mesolimbic dopamine system to reduce hunger and help control cravings.

Also known as: Naltrexone HCl/Bupropion HCl 8 Mg-90 Mg
Contrave

Bupropion is FDA-approved and marketed both as an antidepressant agent (Wellbutrin®) and treatment for smoking cessation (Zyban®) and has shown efficacy in reducing symptoms of depression and drug craving in stimulant users. it is also a promising candidate to improve cognition function.

Also known as: Wellbutrin, Zyban
