Outcome Measures

Primary Outcomes (1)

  • Percent of patients not requiring midazolam for rescue sedation based on achieving and/or maintaining an Observer's Assessment of Alertness/Sedation Scale (OAA/S) score ≤4

    Observer's Assessment of Alertness/Sedation Scale (OAA/S) score ≤4 (Responsiveness: Lethargic response to name spoken in normal tone; Speech: Mild slowing or thickening; Facial Expression: Mild relaxation; Eyes: Glazed or mild ptosis \[less than half the eye\])

    Prior to start of study drug, 15 minutes after start of study drug infusion, every 5 minutes thereafter throughout the study drug infusion and every 15 minutes while the subject is in the post anesthesia care unit.

Secondary Outcomes (9)

  • Total amount (mg) of rescue midazolam required to achieve and/or maintain sedation (OAA/S score ≤4)

    Prior to start of study drug, 15 minutes after start of study drug infusion, every 5 minutes thereafter throughout the study drug infusion and every 15 minutes while the subject is in the post anesthesia care unit.

  • Time from onset of study drug infusion to first dose of rescue midazolam

    After the first 15 minutes of study drug infusion

  • Percentage of subjects who convert to alternative sedative and/or anesthetic therapy due to failure of treatment with study drug and rescue

    Prior to start of study drug, 15 minutes after start of study drug infusion, every 5 minutes thereafter throughout the study drug infusion and every 15 minutes while the subject is in the post anesthesia care unit.

  • Time to recovery and readiness for discharge from Post-Anesthesia Care Unit (PACU)

    Performed every 15 minutes while the subject is in the PACU until subject is discharged.

  • Total amount of fentanyl required for pain control

    After the first 15 minutes of study drug infusion

  • +4 more secondary outcomes

  • Not of childbearing potential, defined as post-menopausal for at least 1 year or surgically sterile due to bilateral tubal ligation, bilateral oophorectomy or hysterectomy.
  • Of childbearing potential but is not pregnant at time of baseline and is practicing one of the following methods of birth control: oral or parenteral contraceptives, double-barrier method, vasectomized partner, or abstinence from sexual intercourse.
  • Subject requires monitored anesthesia care (MAC) in an operating room (OR) or procedure room with an anesthesiologist in attendance.

  • Vascular stents
  • Breast biopsies
  • AV fistulas
  • Excision of lesion.
  • Subject requires local anesthetic block.
  • +1 more criteria

You may not qualify if:

  • Subject has received general anesthesia within 7 days prior to study entry, has received any experimental drug within 30 days prior to study drug administration, or has been previously enrolled in this study.
  • Subject requires endotracheal intubation or laryngeal mask airway (LMA)
  • Subject has central nervous system (CNS) disease with an anticipated potential for increased intracranial pressure, an uncontrolled seizure disorder, and/or known psychiatric illness that could confound a normal response to sedative treatment.
  • Subject requires epidural or spinal anesthesia.
  • Subject has received treatment with an alpha-2 agonist or antagonist within 14 days of the scheduled surgery/procedure.
  • Subject for whom opiates, benzodiazepines, dexmedetomidine, or other alpha-2 agonists are contraindicated.
  • Subject has received an intravenous (IV) opioid within one hour, or a by mouth (PO)/intramuscular (IM) opioid within 4 hours, of the start of study drug administration.
  • Subject has acute unstable angina, acute myocardial infarction documented by laboratory findings in the past 6 weeks, heart rate \<50 bpm, systolic blood pressure (SBP) \<90 mmHg, or third-degree heart block unless patient has a pacemaker.
  • Subject has known elevated serum glutamic pyruvic transaminase (SGPT/Alanine aminotransferase \[ALT\]) and/or serum glutamic oxaloacetic transaminase (SGOT/aspartate Aminotransferase \[AST\]) values of ≥2 times the upper limit of normal within the 2 months prior to screening, and/or a history of liver failure.
  • Subject has any other condition or factor which, in the Investigator's opinion, might increase the risk to the subject.
