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
  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Healthy female subjects of non-childbearing potential and/or male subjects. Healthy is defined as no clinically relevant abnormalities identified by a detailed medical history, full physical examination, including BP and pulse rate measurement, 12-lead ECG, or clinical laboratory tests.
  • Body mass index (BMI) of 17.5 to 30.5 kg/m2; and a total body weight >50 kg (110 lb) at screening.
  • Evidence of a personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the study.
  • Subjects who are willing and able to comply with all scheduled visits, treatment plan, laboratory tests, and other study procedures.

Who cannot join

  • Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic (including alcoholic liver disease, nonalcoholic steatohepatitis (NASH), autoimmune hepatitis, and hereditary liver diseases), psychiatric, neurological, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at the time of dosing)
  • Self-reported history or risk factors for QT prolongation or torsades de pointes (eg, organic heart disease, congestive heart failure, hypokalemia, hypomagnesaemia, congenital long QT syndrome, myocardial ischemia or infarction), congenital deafness, family history of sudden death, and family history of long QT syndrome.
  • Treatment with an investigational drug within 30 days (or as determined by the local requirement) or 5 half-lives preceding the first dose of investigational product (whichever is longer)
  • Subjects with known prior participation (ie, randomized and received at least 1 dose of investigational product) in a trial involving PF-06700841
  • History of tuberculosis or active or latent or inadequately treated infection, positive QuantiFERON- tuberculosis (TB) Gold test
  • History of human immunodeficiency virus (HIV), hepatitis B, or hepatitis C; positive testing for HIV, hepatitis B surface antigen (HepBsAg), hepatitis B core antibody (HepBcAb), or hepatitis C antibody (HCVAb)
  • Blood donation (excluding plasma donations) of approximately 1 pint (500 mL) or more within 60 days prior to dosing
  • Other acute or chronic medical or psychiatric condition including recent (within the past year) or active suicidal ideation or behavior or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the subject inappropriate for entry into this study.

About this study

Official title: A PHASE 1, RANDOMIZED, PLACEBO-AND POSITIVE-CONTROLLED CROSSOVER STUDY TO DETERMINE THE EFFECT OF SINGLE-DOSE PF-06700841 ON QTC INTERVAL IN HEALTHY VOLUNTEERS

A phase 1, 6-sequence, 3-period, subject- and investigator blinded and sponsor-open, crossover study in healthy volunteers to evaluate the PF-06700841 effect on QTc interval. Each subject randomized will receive placebo, PF-06700841 200 mg and moxifloxacin (open label) in one of the 6 sequences. Moxifloxacin is positive control to demonstrate the study sensitivity and PF-06700841 effect on QTc will be assessed by concentration-QT analysis

What is being measured

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

  1. QTc change from baseline following PF-06700841 treatment

    QTc change from baseline at geometric mean of maximum concentrations observed after single doses of 200 mg PF-06700841 and maximum concentrations expected at lower doses of 30 and 60 mg.

    Measured: 0 to 48 hours post-dose

Secondary outcomes (1)
  1. QTc change from baseline following moxifloxacin treatment

    QTc change from baseline at 3 hours (Tmax) after a single dose of 400 mg moxifloxacin administration

    Measured: 0-48 hours post-dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PF-06700841 and moxifloxacin in people with Healthy, run by Pfizer at 1 site in Belgium.

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 8 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 27 Feb 2019. 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 Belgium. 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

QTc change from baseline following PF-06700841 treatment (time frame: 0 to 48 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 NCT03656952, 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 27 Feb 2019; AzTrials last refreshed its copy on 30 Oct 2026.
