About this study

Official title: Phase 1, Randomized, Patient And Investigator-blind, Placebo-controlled Study To Investigate The Safety, Tolerability, Pharmacokinetics And Pharmacodynamics Of Multiple Intravenously Administered Doses Of Pf-04236921 In Patients With Rheumatoid Arthritis Receiving Methotrexate

This study will evaluate the safety and tolerability of PF-04236921 administered monthly as three intravenous infusions. Each group of patients will be assigned to a dose level; Safety and tolerability of a low dose level will be required before proceeding to successively higher dose levels. Blood tests will be performed to measure the amount of drug and changes in measures of inflammation.

What is being measured

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

  1. Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)

    An AE was any untoward medical occurrence in a participant who received study medication without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study medication and up to 28 days after last dose or until serum PF-04236921 concentrations were below the LLOQ that were absent before treatment or that worsened relative to pretreatment state. AEs included both serious and non-serious adverse events.

    Measured: Baseline up to 28 days after last dose of study medication or until serum PF-04236921 concentrations below the LLOQ (up to Day 624)

  2. Number of Participants With Positive Anti-drug Antibodies Response

    Measured: Day 1, 28, 56, 84, 174, 354, End of Study (Day 624)

  3. Maximum Observed Serum Concentration (Cmax): Day 1

    Measured: Day 1: Pre-dose (0 hour), 15 minutes, 168 hours, 336 hours post-dose

  4. Time to Reach Maximum Observed Serum Concentration (Tmax): Day 1

    Measured: Day 1: Pre-dose (0 hour), 15 minutes, 168 hours, 336 hours post-dose

  5. Area Under the Curve From Time Zero to Last Quantifiable Concentration [AUC (0-168)]: Day 1

    AUC (0-168) = Area under the serum concentration versus time curve from time zero (pre-dose) to 168 hours (0-168).

    Measured: Day 1: Pre-dose (0 hour), 15 minutes, 168 hours post-dose

  6. Maximum Observed Serum Concentration (Cmax): Day 28

    Measured: Day 28: Pre-dose (0 hour), 15 minutes, 168 hours, 336 hours post-dose

  7. Time to Reach Maximum Observed Serum Concentration (Tmax): Day 28

    Measured: Day 28: Pre-dose (0 hour), 15 minutes, 168 hours, 336 hours post-dose

  8. Area Under the Curve From Time Zero to Last Quantifiable Concentration [AUC (0-168)]: Day 28

    AUC (0-168) = Area under the serum concentration versus time curve from time zero (pre-dose) to 168 hours (0-168).

    Measured: Day 28: Pre-dose (0 hour), 15 minutes, 168 hours post-dose

  9. Maximum Observed Serum Concentration (Cmax): Day 56

    Measured: Day 56: Pre-dose (0 hour), 15 minutes, 168 hours, 336 hours, 672 hours post-dose

  10. Time to Reach Maximum Observed Serum Concentration (Tmax): Day 56

    Measured: Day 56: Pre-dose (0 hour), 15 minutes, 168 hours, 336 hours, 672 hours post-dose

  11. Area Under the Curve From Time Zero to Last Quantifiable Concentration [AUC (0-168)]: Day 56

    AUC (0-168) = Area under the serum concentration versus time curve from time zero (pre-dose) to 168 hours (0-168).

    Measured: Day 56: Pre-dose (0 hour), 15 minutes, 168 hours post-dose

  12. Serum Decay Half-Life (t1/2): Day 56

    Serum decay half-life is the time measured for the serum concentration to decrease by one half.

    Measured: Day 56: Pre-dose (0 hour), 15 minutes, 168 hours, 336 hours, 672 hours post-dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing dose level 1, dose level 2 and dose level 3 in people with Rheumatoid Arthritis, run by Pfizer at 8 sites in 3 countries.

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 2 inclusion and 3 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 2 Nov 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in United States, South Korea, Spain. 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 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?

Yes. Results are posted in the registry (first posted 2 Nov 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?

Number of Participants With Treatment-Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs) (time frame: Baseline up to 28 days after last dose of study medication or until serum PF-04236921 concentrations below the LLOQ (up to Day 624)). The study lists 12 primary outcomes in all. 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 NCT00838565, 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 2 Nov 2018.
