Methamphetamine Intoxication, Methamphetamine Disorders, Methamphetamine Abuse
Conditions
Brief summary
The purpose of the study is to evaluate the safety, efficacy, and pharmacokinetics of four single, increasing doses of CS-1103, given by intravenous (IV) infusion in otherwise healthy, non-treatment seeking participants with methamphetamine use disorder in the presence of a clinically relevant dose of methamphetamine HCl (30 mg IV).
Interventions
Methamphetamine HCl for intravenous administration
Sterile Saline for intravenous administration
CS-1103 for intravenous administration

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of participants with CS-1103-related adverse events (AEs) assessed by physical examinations | 3 days plus follow-up on Day 10 | Physical examinations |
| Number of participants with CS-1103-related adverse events (AEs) assessed by electrocardiograms (ECGs) | 3 days plus follow-up on Day 10 | Digital 12-lead electrocardiograms (ECGs). Any correlation between CS-1103 plasma concentrations and changes in QT intervals will be noted. |
| Number of participants with CS-1103-related adverse events (AEs) assessed by vital signs | 3 days plus follow-up on Day 10 | Blood pressure, pulse rate, respiratory rate, oxygen saturation, and body temperature |
| Number of participants with CS-1103-related adverse events (AEs) assessed by laboratory parameters | 3 days plus follow-up on Day 10 | Clinical chemistry, hematology, coagulation, and urinalysis |
| Time course and magnitude of urine excretion of methamphetamine | 48 hours | Measurement of concentration of methamphetamine in urine |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time course of CS-1103 blood and urine concentrations | 48 hours | Measurement of plasma and urine concentrations of CS-1103 |
