Outcome Measures
Primary Outcomes (4)
Reinforcing Effects of Methamphetamine Following Methylphenidate (0 mg; Placebo) Maintenance.
Number of methamphetamine doses earned by subjects on a progressive ratio schedule of reinforcement. Subjects sample a dose of methamphetamine (0, 10, or 20 mg) and then have ten opportunities (e.g., trials) to "work" for a 1/10th of the sampled dose via clicking on a computer mouse (i.e., 10 completed trials is the full sampled dose).
Following at least 4 days of maintenance on placebo during inpatient admission, up to 1 week
Reinforcing Effects of Methamphetamine Following Methylphenidate (20 mg) Maintenance.
Number of methamphetamine doses earned by subjects on a progressive ratio schedule of reinforcement. Subjects sample a dose of methamphetamine (0, 10, or 20 mg) and then have the ten opportunities (e.g., trials) to "work" for a 1/10th of the sampled dose via clicking on a computer mouse (i.e., 10 completed trials is the full sampled dose).
Following at least 4 days of maintenance on drug during inpatient admission, up to 1 week
Reinforcing Effects of Methamphetamine Following Methylphenidate (40 mg) Maintenance.
Number of methamphetamine doses earned by subjects on a progressive ratio schedule of reinforcement. Subjects sample a dose of methamphetamine (0, 10, or 20 mg) and then have the ten opportunities (e.g., trials) to "work" for a 1/10th of the sampled dose via clicking on a computer mouse (i.e., 10 completed trials is the full sampled dose).
Following at least 4 days of maintenance on drug during inpatient admission, up to 1 week
Reinforcing Effects of Methamphetamine Following Methylphenidate (60 mg) Maintenance.
Number of methamphetamine doses earned by subjects on a progressive ratio schedule of reinforcement. Subjects sample a dose of methamphetamine (0, 10, or 20 mg) and then have the ten opportunities (e.g., trials) to "work" for a 1/10th of the sampled dose via clicking on a computer mouse (i.e., 10 completed trials is the full sampled dose).
Following at least 4 days of maintenance on drug during inpatient admission, up to 1 week

Study Arms (2)
Placebo Comparator: Placebo
PLACEBO COMPARATORSubjects will be maintained on oral placebo. Subjects will be maintained on placebo and methylphenidate during placebo maintenance. Methamphetamine will be administered acutely during placebo maintenance. Placebo will be administered acutely during placebo maintenance.
Active Comparator: Duloxetine
ACTIVE COMPARATORSubjects will be maintained on oral duloxetine. Subjects will be maintained on duloxetine and methylphenidate during placebo maintenance. Methamphetamine will be administered acutely during duloxetine maintenance. Placebo will be administered acutely during duloxetine maintenance.
Interventions
In each arm, subjects will receive doses of methamphetamine.
In each arm, subjects will receive methylphenidate capsules.
In each arm, subjects will receive placebo capsules.
Subjects will receive duloxetine capsules in the duloxetine arm.
Eligibility Criteria
You may qualify if:
- recent use of inhaled (i.e., snorted), smoked or injected methamphetamine
You may not qualify if:
- Abnormal screening outcome (e.g., ECG, blood chemistry result) that study physicians deem clinically significant.
- Current or past histories of substance use that are deemed by the study physicians to interfere with study completion.
- History of serious physical disease, current physical disease, impaired cardiovascular functioning, chronic obstructive pulmonary disease, history of seizure or current or past histories of serious psychiatric disorder that in the opinion of the study physician would interfere with study participation will be excluded from participation.
- Females not currently using effective birth control.
- Contraindications to methamphetamine, methylphenidate, or duloxetine.
