Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 55 years
  • Men only
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Healthy male subjects who, at the time of screening, are between 18 and 55 years of age, inclusive. Healthy is defined as no clinically relevant abnormalities identified by a detailed medical history, full physical examination, including blood pressure and pulse rate measurement, 12 lead ECG and clinical laboratory tests.
  • The subject must have a normal, stable body temperature at Screening and on Day 0. If the subject's oral temperature is not between 97.4°F and 98.8°F, then 2 additional oral temperature readings will be obtained within a 30 minute period. These 3 consecutive temperature readings must be between 97.4°F and 98.8°F, with the highest value within 0.4°F of the lowest temperature value.
  • Body Mass Index (BMI) of 17.5 to 37.0 kg/m2; and a total body weight 50 kg (110 lbs) at Screening.
  • The subject has demonstrably adequate veins, by visual inspection, for IV catheter insertion.

Who cannot join

  • Evidence or history of clinically significant laboratory abnormality, hematological, renal, endocrine, pulmonary, cardiovascular, hepatic, psychiatric, neurologic, or allergic disease (excluding untreated, asymptomatic, seasonal allergies at the time of dosing) within the last 5 years that may increase the risk associated with study participation.
  • Subjects with any gastrointestinal disorders (eg, gastrectomy, tracheostomy, esophageal surgeries, short gut syndrome, peptic ulcer disease, known or suspected obstructive disease, previous gastrointestinal surgery, felinization of the esophagus, hypomotility of the gastrointestinal track) that could affect the absorption, metabolism, or excretion of the study medication or affect the results of the ingestible thermometer.
  • Subjects at risk for excessive bleeding.
  • Subjects with a history of nasal polyps, angioedema, or significant or actively treated bronchospastic disease.
  • Screening supine blood pressure ≤90 or ≥140 mm Hg (systolic) or ≤50 or ≥90 mm Hg (diastolic), following at least 5 minutes of supine rest. If blood pressure (BP) is ≤90 or ≥140 mm Hg (systolic) or ≤50 or ≥90 mm Hg (diastolic), the BP should be repeated two more times and the average of the three consecutive BP values should be used to determine the subject's eligibility.
  • Screening supine 12 lead ECG demonstrating QTc >450 msec or a QRS interval >120 msec at Screening and on Day 1 prior to RSE administration. If QTc exceeds 450 msec, or QRS exceeds 120 msec, the ECG should be repeated two more times and the average of the three consecutive QTc or QRS values should be used to determine the subject's eligibility.
Show all 9Show fewer
  • The subject has a history of recurrent or acute or chronic infections of any type or any findings suggestive of occult infection, such as tuberculosis, sinusitis, urinary tract infection, respiratory tract or dental (abscess) infection, etc., or those with a positive QuantiFERON Tuberculosis, Hepatitis B surface antigen, Hepatitis C antibody, and/or Human immunodeficiency virus (HIV) test at Screening. Also excluded are subjects with frequent (more than 3 outbreaks per year), recurrent oral or genital herpes, recurrent herpes zoster, or any infection otherwise judged by the investigator to have the potential for exacerbation by participation in the study.
  • Subjects who have experienced cold/flu symptoms (ie, runny nose, cough, and/or fever) within 2 weeks prior to the first administration of study treatments.
  • Subjects with a reduction in heart rate to ≤50 beats per minute or deemed to be at high risk of syncope and/or hypotension per the clinical judgment of the investigator following a carotid sinus massage procedure.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Time Weighted Sum of Temperature Difference (WSTD) From 0 to 8 Hours

    WSTD 0-8 was defined as time-weighted sum of temperature differences over 8 hours, weighted by time elapsed between each 2 consecutive time points post treatment (10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110 minutes, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5 and 8 hours). Temperature difference was defined as baseline temperature (at 0 hour) minus the post-baseline temperature at each time point up to 8 hours (10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110 minutes, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5 and 8 hours).

    Measured: 0 to 8 hours post-dose

Secondary outcomes (4)
  1. Time Weighted Sum of Temperature Differences (WSTD) From Baseline Through Hours 2, 4 and 6

    WSTD 0-2, 0-4 and 0-6 was defined as time-weighted sum of temperature differences over each specified time interval (0-2 hour, 0-4 hour and 0-6 hour), weighted by time elapsed between each 2 consecutive time points post treatment (10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110 minutes, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6 hour), within each time interval. Temperature difference was defined as baseline temperature (at 0 hour) minus the post-baseline temperature at each time point within each specified time interval: 1) 0-2 hour (20, 30, 40, 50, 60, 70, 80, 90, 100, 110 minutes) , 2) 0-4 hour (10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110 minutes, 2, 2.5, 3, 3.5, 4 hour), 3) 0-6 hour (10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110 minutes, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6 hour).

    Measured: 0 to 2 hours postdose, 0 to 4 hours postdose, 0 to 6 hours postdose

  2. Time to Return to Normal Body Temperature

    Time to return to normal body temperature was defined as time from initial measurement of normal body temperature (at baseline; before administration of first test dose of RSE to induce pyrexia) till the time at which normal temperature was achieved again after pyrexia. Normal body temperature was defined as the last non-missing body temperature value, assessed prior to or at the time of first RSE test dose.

    Measured: Baseline (pre-dose) up to 8 hours post dose

  3. Time to Rescue Medication

    Time to rescue medication (other than study treatment) (in minutes) was defined as time from first dosing of study medication to the time a participant first takes a rescue medication, or to the end of the study time for participants that do not take any rescue medication prior to the end of the study. The rescue medication was defined as medication received for the treatment of fever during the time period from the administration of study medication to the time of end of the study.

    Measured: 0 to 8 hours post dose

  4. Time Weighted Sum of Temperature Difference From 6 to 8 Hours

    WSTD 6-8 was defined as time-weighted sum of temperature differences between 6 to 8 hours post-dose, weighted by time elapsed between each 2 consecutive time points within 6 to 8 hours (6.5, 7, 7.5 and 8 hours). Temperature difference was defined as temperature at 6 hours minus the temperature at specified time points (6.5, 7, 7.5 and 8 hours).

    Measured: 6 to 8 hours postdose

What is this clinical trial studying?

A Phase 3 study testing Ibuprofen 250 mg / Acetaminophen 500 mg, Ibuprofen 250 mg and Acetaminophen 500 mg in people with Fever, run by Pfizer at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 7 Dec 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Time Weighted Sum of Temperature Difference (WSTD) From 0 to 8 Hours (time frame: 0 to 8 hours post-dose). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02761980, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Dec 2018.
