Study summary

The primary objective of this study is to evaluate the safety and tolerability of different dose levels of glyburide for injection, administered as a bolus dose followed by a 3-day continuous infusion. The secondary objectives are to assess the pharmacokinetics (PK) of glyburide and blood glucose and serum insulin pharmacodynamic (PD) responses to glyburide.

Exclusion criteria

Exclusion Criteria:

  1. Clinically significant history of hypoglycemia as assessed by the investigator.
  2. History of seizure disorder, even if currently not receiving anticonvulsant medications.
  3. History of adverse reaction to glyburide, other sulfonylurea class of anti-diabetic medications, or other sulfa drugs.
  4. Glucose-6-phosphate dehydrogenase (G6PD) deficiency as determined by G6PD enzyme testing at screening.
  5. Be an active smoker or user of other forms of tobacco. Former smokers or tobacco users must have refrained from smoking or using other forms of tobacco for at least 6 months prior to dosing on Study Day 1.
  6. A history or clinical manifestations of significant metabolic (including diabetes mellitus, hypercholesterolemia, or dyslipidemia), hematologic, pulmonary, cardiovascular, gastrointestinal, neurologic, hepatic, renal, urologic, immunologic, or psychiatric disorders (a history of mild depression, currently not receiving therapy, is acceptable).
  7. Use any prescription medication within 14 days prior to randomization, or nonprescription drugs within 7 days. Exceptions may be made by the medical monitor on a case-by-case basis.
  8. Received another investigational drug within 30 days prior to randomization.
  9. A positive hepatitis virus test (Hepatitis B virus surface antigen or hepatitis C virus antibody) or a positive human immunodeficiency virus (HIV) antibody test at screening. If the HIV test is positive, the subject will be informed privately and referred for additional counseling.

What researchers measure

Primary outcomes

  1. Number of Participants with Adverse Events and Serious Adverse Events

    An adverse event (AE) is defined as any untoward medical occurence such as a sign, symptom, and/or laboratory finding that is concurrent with the use of a drug in humans. A serious adverse event is any AE that is fatal, life-threatening, requires or prolongs hospital stay, results in persistent or significant disability or incapacity, a congenital anomaly or birth defect, or an important medical event

    Time frame: Up to Day 28

Secondary outcomes

  1. Pharmacokinetic (PK) Parameter of Glyburide: Clearance (CL)

    Time frame: Day 1 (baseline) and at multiple time points up to Day 5

  2. PK Parameter of Glyburide: Volume of Distribution (Vz)

    Time frame: Day 1 (baseline) and at multiple time points up to Day 5

  3. PK Parameter of Glyburide: Elimination Rate Constant (λz)

    Time frame: Day 1 (baseline) and at multiple time points up to Day 5

  4. PK Parameter of Glyburide: Half-Life (t1/2)

    Time frame: Day 1 (baseline) and at multiple time points up to Day 5

  5. PK Parameter of Glyburide: Predicted Steady-State Concentration (Css)

    Time frame: Day 1 (baseline) and at multiple time points up to Day 5

  6. PK Paramater of Metabolites (M1 and M2): Maximum Plasma Concentrations (Cmax)
