What is being measured

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

  1. Number of Participants Who Experienced One or More Treatment-emergent Adverse Events (TEAEs)

    TEAEs were adverse events with an onset after the administration of study treatment.

    TEAEs were graded using the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0.

    Grade 2 Moderate; minimal, local or noninvasive intervention indicated; limited age appropriate instrumental activities of daily life (ADL).

    Grade 3 Severe or medically significant but not immediately life-threatening; hospitalization or prolonged hospitalization indicated; disabling; limited self care ADL.

    Grade 4 Life-threatening consequences; urgent interventions indicated.

    Serious adverse events (SAEs) were defined as meeting at least 1 of the following criteria:

    • Results in death (fatal)
    • Immediately life-threatening
    • Requires in-patient hospitalization or prolongation of existing hospitalization
    • Results in persistent or significant disability/incapacity
    • Is a congenital anomaly/birth defect
    • Other medically important serious event

    Measured: Day 1 to Day 105

  2. Number of Participants Who Experienced a Clinically Significant Change in Physical Examinations

    Physical examinations were performed by the investigator, designated physician, or nurse practitioner. A complete physical examination included, at a minimum, assessment of cardiovascular, respiratory, gastrointestinal and neurological systems. A brief physical examination included assessment of the skin, lungs, cardiovascular system, and abdomen (liver and spleen).

    Measured: Baseline to Day 105

  3. Number of Participants Who Experienced a Clinically Significant Change in Vital Signs

    Any changes in blood pressure, body temperature, heart rate, and pulse rate that were deemed as clinically significant by the Investigator were reported.

    Measured: Baseline to Day 105

  4. Number of Participants Who Experienced a Clinically Significant Change in Clinical Laboratory Safety Tests

    Laboratory safety tests included chemistry, hematology, and urinalysis parameters. Clinically significant laboratory safety tests were any events assessed as CTCAE Grade ≥3 at any post-baseline visit.

    Grade 3 Severe or medically significant but not immediately life-threatening; hospitalization or prolonged hospitalization indicated; disabling; limited self care ADL.

    Grade 4 Life-threatening consequences; urgent interventions indicated.

    Measured: Baseline to Day 105

  5. Number of Participants Who Experienced a Clinically Significant Change in Electrocardiograms (ECGs)

    Any changes in ECG parameters that were deemed clinically significant by the Investigator were reported.

    Measured: Baseline to Day 105

Secondary outcomes (8)
  1. Maximum Observed Concentration (Cmax) of AMG 570

    AMG 570 pharmacokinetic (PK) parameters were estimated using non-compartmental analysis.

    Measured: Pre-dose and 12 hours post-dose on Day 1 and days 2, 3, 4, 6, 8, 11, 15, 22, 29, 43, 57, 71 and 105

  2. Time to Reach Maximum Observed Concentration (Tmax) of AMG 570

    AMG 570 PK parameters were estimated using non-compartmental analysis.

    Measured: Pre-dose and 12 hours post-dose on Day 1 and days 2, 3, 4, 6, 8, 11, 15, 22, 29, 43, 57, 71 and 105

  3. Area Under the Concentration-time Curve From Time 0 to Time of the Last Quantifiable Concentration (AUClast) of AMG 570

    AMG 570 PK parameters were estimated using non-compartmental analysis.

    Measured: Pre-dose and 12 hours post-dose on Day 1 and days 2, 3, 4, 6, 8, 11, 15, 22, 29, 43, 57, 71 and 105

  4. Area Under the Concentration-time Curve Observed From Time Zero to Infinity (AUCinf) of AMG 570

    Measured: Pre-dose and 12 hours post-dose on Day 1 and days 2, 3, 4, 6, 8, 11, 15, 22, 29, 43, 57, 71 and 105

  5. Number of Participants With an Anti-AMG 570 Binding Antibody Positive Postbaseline Result

    The presence of anti-AMG 570 binding antibodies was assessed using a validated assay. The number and percentage of participants who developed binding anti-AMG 570 antibodies at any postbaseline visit are presented.

    Measured: Baseline to Day 105

  6. Mean Peripheral Blood B7-Related Protein-1 (B7RP-1) Receptor Occupancy on Total B Cells

    Peripheral B7RP1 (also known as inducible costimulator ligand [ICOSL]) receptor occupancy was calculated from the free ICOSL and total ICOSL measurement from B cells in whole blood.

    Measured: Day 8; Day 29; Day 57; and Day 105

  7. Percentage Change From Baseline for Cluster of Differentiation (CD)19+ Total B Cells Counts

    Measured: Baseline to Day 8; Day 29; Day 57 and Day 105

  8. Percentage Change From Baseline for CD19+ Total B Cells Percentages (%)

    Measured: Baseline to Day 8; Day 29; Day 57 and Day 105

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing AMG 570 in people with Systemic Lupus Erythematosus, run by Amgen at 3 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 5 inclusion and 5 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 14 May 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 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. 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 15 Oct 2021). 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 Who Experienced One or More Treatment-emergent Adverse Events (TEAEs) (time frame: Day 1 to Day 105). The study lists 5 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 NCT02618967, 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 14 May 2024.
