About this study

Official title: A Phase 2a, Open Label, Multiple-Dose Study to Evaluate Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Immunogenicity of Teplizumab in Adults With Moderate or More Severe Psoriasis

The purpose of this study is to determine whether teplizumab is safe when administered subcutaneously (by needle under the skin) in subjects with psoriasis. The study will also evaluate how long teplizumab stays in the blood and how long it takes for it to leave the body, what is the highest dose that can safely be given, and whether it improves psoriasis.

Read the detailed description

This study will test the hypotheses that therapeutic modulation of T-cell function by teplizumab is well tolerated in subjects with moderate or more severe psoriasis, and that this treatment ameliorates the immunopathology of psoriasis. This study will evaluate the safety, pharmacokinetics (PK), and pharmacodynamics (PD) of subcutaneous (SC) administration for 6 days. Once the SC maximum tolerated dose is identified, this dose will be administered to a cohort of subject by intravenous for comparison of PK and PD.

What is being measured

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

  1. Adverse Events (AE)

    Primary endpoints include safety data such as vital signs, physical examinations, electrocardiograms, AE reports, and laboratory test results.

    Measured: Day 0 through Day 84

Secondary outcomes (4)
  1. Number of Participants Improved on Lattice System Physician's Global Assessment (LS-PGA)

    The LS-PGA score is determined by estimating the extent of body surface area involved by psoriasis and rating plaque qualities (elevation, erythema, scaling) averaged over the entire body. LS-PGA score is then determined using available software. LS-PGA ranks involvement on an 8 point scale from clear, almost clear, mild, mild to moderate, moderate, moderate to severe, severe, and very severe. Participants who have an improvement of one or more steps in the LS-PGA will be considered to have met the primary criteria for a clinical response.

    Measured: Day 0, 14, 28, 63 and 84

  2. Number of Participants Improved on the Psoriasis Area and Severity Index (PASI)

    The PASI combines assessments of the extent of body-surface involvement in 4 anatomical regions (head, trunk, arms, and legs) and the severity of plaque scale, erythema, and plaque induration (thickness) in each region, yielding an overall score of 0 for no psoriasis to a maximum of 72 for severe disease.

    Measured: Day 0, 14, 28, 63 and 84

  3. Physician's Global Assessment (PGA)

    The PGA rates the subject's psoriasis relative to baseline as 1 (100% clearing), 2 (excellent: 75% through 99% clearing with striking improvement), 3 (good: 50% through 74% clearing with moderate improvement), 4 (fair: 25% through 49% clearing with slight improvement), 5 (poor: 0% through 24% clearing with little or no change), or 6 (worsening). Involvement of body-surface area, induration, scaling, and erythema are taken into account.

    Measured: Day 0, 14, 28, 63 and 84

  4. Teplizumab Blood Levels

    Measured: Day 0 through Day 84

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing teplizumab in people with Psoriasis, run by MacroGenics at 2 sites 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 3 inclusion and 17 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: stopped early, as of the sponsor's last update on 10 Feb 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 19 Apr 2012). 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?

Adverse Events (AE) (time frame: Day 0 through Day 84). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 10 Feb 2022.
