Details and patient eligibility

About

Based on the pharmacological class of rapastinel, this study will be conducted to evaluate the abuse potential of single doses of rapastinel as compared with ketamine, a NMDAR antagonist that is a Schedule III dissociative anesthetic, and placebo in recreational polydrug users.

Inclusion criteria

Participant must be a current recreational polydrug user
Have a supine systolic blood pressure (BP) ≥ 95 mm Hg and ≤ 145 mg Hg, or supine diastolic BP ≥ 50 mm Hg and ≤ 90 mm Hg at the Screening Visit.
Have negative test results for benzoylecgonine (cocaine), methadone, barbiturates, amphetamines, benzodiazepines, alcohol, oxycodone and other opioids, and phencyclidine at any admission

History of violent or psychotic behavior when taking psychedelic drugs, or unwilling to take a drug that might alter perception in a controlled setting
Have taken or require concomitant treatment with any CNS depressants, or cannot safely discontinue these medications within 14 days (or 5 half-lives, whichever is longer) before study treatment administration
Previously participated in an investigational study of rapastinel.
Participation in any other clinical investigation using an experimental drug within 30 days, 5 half-lives or twice the duration of the biological effect of the study treatment (whichever is longer), prior to study treatment administration or is concurrently enrolled in any clinical trial, judged not to be scientifically or medically compatible with this study
Consumption of alcohol within 72 hours before administration of study treatment
Breastfeeding
Unable to refrain from consuming caffeine or xanthine-containing compounds such as tea, coffee, soft drinks, energy sports drinks or chocolate (more than 48 oz/day) from 48 hours before administration of study treatment.
Have consumed dietary supplements or other foods or beverages that may affect various drug metabolizing enzymes and transporters (eg, grapefruit, grapefruit juice, grapefruit-containing beverages), vegetables from the mustard green family (eg, kale, broccoli, watercress, collard greens, kohlrabi, Brussels sprouts, mustard), and charbroiled meats within 14 days prior to dosing or unable to refrain from consumption during the study.
