A Phase 1 Study to Evaluate Pregabalin and Acetaminophen in Healthy Volunteers
Study Details
Study Description
Brief Summary
This is a Phase 1, randomized, double-blind, placebo-controlled, single and multiple ascending dose study to determine a maximum tolerated dose of IV PGB and to evaluate the safety, tolerability, and PK of an admixture of IV PGB and a fixed dose of 1300 mg IV APAP in healthy adult volunteers.

Phase 1 |
Detailed Description
This is a Phase 1, randomized, double-blind, placebo-controlled, single and multiple ascending dose study to determine a maximum tolerated dose (MTD) of IV PGB and to evaluate the safety, tolerability, and PK of an admixture of IV PGB and a fixed dose of 1300 mg IV APAP in healthy adult volunteers.
Up to 60 subjects will be enrolled into one (1) of six (6) sequential cohorts (n=10 per cohort [8 APAP + PGB and 2 placebo]).
The dose for the first cohort will be 1300 mg APAP and 100 mg PGB. For subsequent cohorts, the dose of APAP will remain constant at 1300 mg while the dose of PGB will be varied (will start with 100 mg TID and then based on tolerability will be either increased or decreased by 25 mg) based on Safety Monitoring Committee decision.
The placebo will be the saline solution.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: 1300 mg Acetaminophen and 100 mg IV Pregabalin The dose for the first cohort will be 1300 mg APAP and 100 mg PGB. For subsequent cohorts, the dose of APAP will remain constant at 1300 mg while the dose of PGB will be varied (will start with 100 mg TID and then based on tolerability will be either increased or decreased by 25 mg based on Safety Monitoring Committee decision). |
Drug: Pregabalin 100mg
Pregabalin is a structural derivative of the inhibitory neurotransmitter gamma aminobutyric acid with anticonvulsant, anxiolytic and sleep-modulating properties.
Other Names:
Drug: Acetaminophen 1300mg
Acetaminophen is a non-salicylate antipyretic and non-opioid analgesic agent.
Other Names:

| No Intervention: Placebo Saline solution |
|
| Experimental: 1300 mg Acetaminophen and 100 mg +/- 25 IV Pregabalin Decisions to escalate or decrease the dose for Cohorts 2 through 6 will be dependent upon blinded review of emerging safety and tolerability data by the Safety Monitoring Committee (SMC). However, PK data is not part of the SMC review, but may be reviewed by a SMC designee at a later time. |
