Brief Summary

To assess the rapidity of onset of antipyretic effect and the efficacy and safety of a single dose of IV acetaminophen (IV APAP) versus oral (PO) acetaminophen in the treatment of fever induced by a standard dose of endotoxin

Detailed Description

A Phase III, Randomized, Double-Blind, Double-Dummy, Single-Dose Study of the Efficacy and Safety of Intravenous Acetaminophen Versus Oral Acetaminophen for the Treatment of Endotoxin-Induced Fever in Healthy Adult Males

Conditions

Fever

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: TRIPLE

Study Groups

IV acetaminophen plus oral placebo.

Administration of a 1 ng/kg body weight test dose of RSE to test for fever response. Observation period of at least 60 minutes to ensure no exaggerated systemic responses, followed by administration of a 4 ng/kg of RSE to induce fever. Randomization to receive 1 g of acetaminophen in 100 ml of intravenous solution and oral placebo.

Group Type: EXPERIMENTAL

Intravenous acetaminophen plus oral placebo

Intervention Type: DRUG

Single dose of 1 gm IV acetaminophen

Reference standard endotoxin (RSE)

Intervention Type: BIOLOGICAL

To subjects in both study arms: Administration of a 1 ng/kg body weight test dose of RSE to induce fever and test for fever response. Observation period of at least 60 minutes to ensure no exaggerated systemic responses, followed by administration of a 4 ng/kg of RSE to induce fever.

Oral acetaminophen plus IV placebo.

Administration of a 1 ng/kg body weight test dose of RSE to test for fever response. Observation period of at least 60 minutes to ensure no exaggerated systemic responses, followed by administration of a 4 ng/kg of RSE to induce fever. Randomization to receive oral acetaminophen 1 g plus 100 ml of intravenous placebo solution.

Group Type: ACTIVE_COMPARATOR

Oral acetaminophen plus IV placebo

Intervention Type: DRUG

Single dose of 1 g PO APAP

Reference standard endotoxin (RSE)

Intervention Type: BIOLOGICAL

To subjects in both study arms: Administration of a 1 ng/kg body weight test dose of RSE to induce fever and test for fever response. Observation period of at least 60 minutes to ensure no exaggerated systemic responses, followed by administration of a 4 ng/kg of RSE to induce fever.

Interventions

Intravenous acetaminophen plus oral placebo

Single dose of 1 gm IV acetaminophen

Intervention Type: DRUG

Oral acetaminophen plus IV placebo

Single dose of 1 g PO APAP

Intervention Type: DRUG

Reference standard endotoxin (RSE)

To subjects in both study arms: Administration of a 1 ng/kg body weight test dose of RSE to induce fever and test for fever response. Observation period of at least 60 minutes to ensure no exaggerated systemic responses, followed by administration of a 4 ng/kg of RSE to induce fever.

Intervention Type: BIOLOGICAL

Eligibility Criteria

Inclusion Criteria

• Provide written Informed Consent prior to participation in the Study
• Be a healthy male between the ages of 18 and 75 years of age, inclusive, at Randomization
• Have a Body Mass Index (BMI) ≥ 19 and ≤ 45 lbs/in2
• Have the ability to read and understand the Study procedures and have the ability to communicate meaningfully with the Study Investigator and staff
• Be free of physical, mental, or medical conditions which, in the opinion of the Investigator, may confound quantifying assessments for the Study
• Be willing to abstain from smoking cigarettes or using nicotine products from the time of admission to Clinic until Study Completion

• Be free of evidence of infection based upon clinical assessment and blood (Complete Blood Count- CBC) and urine testing
• Have an average baseline oral temperature that is equal to or below 37 ºC (98.6 ºF) and does not vary more than 0.4 ºC (0.7 ºF) from lowest to highest on three assessments performed during a 30-minute period
• Not develop a medically significant allergic or exaggerated systemic response to administration of a test dose of reference standard endotoxin
• Develop a core temperature of at least 38.6 ºC (101.5 ºF) after IV reference standard endotoxin dosed per Study guidelines and have a fever response to endotoxin that is at or near the peak temperature by virtue of two consecutive temperature assessments 5 minutes apart that are within 0.2 ºC (0.4 ºF) of each other

Exclusion Criteria

• Has been treated with any medication having antipyretic effects (e.g., corticosteroid,non-steroidal anti-inflammatory drug [NSAID], aspirin, or acetaminophen) within 2 days of clinic admission (aspirin at low dose for cardiac prophylaxis is allowed, but should not be taken on the day of the Study)
• Has significant medical disease(s), laboratory abnormalities, or condition(s) that in the Investigator's judgment could compromise the Subject's welfare, ability to communicate with the Study staff, complete Study activities, or would otherwise contraindicate Study participation
• Has known hypersensitivity or contraindication to receiving endotoxin that in the Investigator's clinical judgment merits discontinuation from further Study participation
• Has known hypersensitivity to acetaminophen, the inactive ingredients (excipients) of the intravenous (IV) or oral (PO) acetaminophen formulation or the Rescue Medications (ibuprofen, aspirin, and ketorolac)
• Has known or suspected recent history of alcohol or drug abuse or dependence as defined by Diagnostic Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) criteria
• Has a history of nasal polyps, angioedema, significant or actively treated bronchospastic disease, or any other significant medical condition that contraindicates participation in the Study or receiving endotoxin, Study Medication, or Rescue Medication
• Has an active infection or other disease or condition that may cause abnormal alterations in body temperature
• Has impaired liver function, e.g.Alanine aminotransferase (ALT) greater than or equal to 3 times the upper limit of normal, bilirubin greater than 3.0, active hepatic disease, or evidence of clinically significant liver disease (e.g., cirrhosis or hepatitis)
• Has participated in another clinical Study (investigational or marketed product) within 30 days of Screening

• Minimum Eligible Age: 18 Years
• Maximum Eligible Age: 75 Years
• Eligible Sex: MALE
• Accepts Healthy Volunteers: Yes
