About this study
Official title: A Randomized, Double-Blind, Placebo-Controlled, Ascending Multiple Dose Study to Evaluate the Safety, Tolerability and Pharmacokinetics of AMG 157 in Healthy Subjects
The primary objective is to evaluate the safety, tolerability, and immunogenicity of multiple-dose administration of tezepelumab in healthy adults.
Read the detailed description
This study will follow a randomized, multiple-dose, double-blind, placebo-controlled, sequential dose-escalation study design. The study will consist of five subcutaneous (SC) cohorts and one intravenous (IV) cohort. Each dose cohort is planned to enroll 8 participants, randomized such that 6 participants will receive tezepelumab and 2 will receive placebo (3:1 ratio).

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With Treatment-emergent Adverse Events
Adverse events (AEs) include any untoward medical occurrence in a trial participant administered a study drug and does not necessarily have a causal relationship with this treatment. AEs include worsening of a pre-existing medical condition and laboratory value changes requiring therapy or adjustment in prior therapy.
AEs were assessed for severity according to the Common Terminology Criteria for Adverse Events (CTCAE), Version 3, where Grade 1 = Mild AE, Grade 2 = Moderate AE, Grade 3 = severe AE, Grade 4 = life-threatening AE and Grade 5 = death due to AE.
Relationship to study treatment was determined by the investigator.
A serious adverse event (SAE) is defined as an AE that met 1 or more of below criteria:
- was fatal;
- was life threatening;
- required in-patient hospitalization or prolongation of existing hospitalization;
- resulted in persistent or significant disability/incapacity;
- was a congenital anomaly/birth defect;
- other significant medical hazard.
Measured: From first dose of study drug up to day 169
Number of Participants Who Developed Anti-tezepelumab Antibodies After Initiation of Treatment
All study samples (tezepelumab and placebo) were tested using an electrochemiluminescence (ECL) based immunoassay to detect and confirm the presence of antibodies capable of binding to tezepelumab. Samples identified as positive in the immunoassay were tested in a receptor-binding ECL-based assay to detect neutralizing or inhibitory effects toward tezepelumab.
The number of participants with positive anti-tezepelumab binding antibodies / neutralizing antibodies at any time post-baseline with a negative or no result at baseline is reported.
Measured: For Q28D groups: Days 28, 56, 85, 113, and 169; For Q14D and Q7D groups: Days 29, 57, 85, 113, 141, and 169
Secondary outcomes (5)
Time of Maximum Observed Concentration (Tmax) of Tezepelumab
The pharmacokinetic (PK) parameter Tmax was estimated based on the serum concentrations of tezepelumab using noncompartmental methods.
The concentration of tezepelumab in human serum was measured using a validated enzyme-linked immunosorbent assay (ELISA). The lower limit of quantification of the assay was 10 ng/ml.
Measured: First dose: Day 1 predose, end of infusion (EOI; IV cohort only), 4 hours, 3, 7, 14 (Q14D & Q28D only) and 28 days (Q28D only) postdose. Last Dose: Day 57 (Q28D), Day 71 (Q14D) and Day 78 (Q7D) predose, EOI (IV cohort), 4 hours, 3, 7, 14, 28 days postdose
Maximum Observed Concentration (Cmax) of Tezepelumab
The PK parameter Cmax was estimated based on the serum concentrations of tezepelumab using noncompartmental methods. The concentration of tezepelumab in human serum was measured using a validated ELISA. The lower limit of quantification of the assay was 10 ng/ml.
Measured: First dose: Day 1 predose, end of infusion (EOI; IV cohort only), 4 hours, 3, 7, 14 (Q14D & Q28D only) and 28 days (Q28D only) postdose. Last Dose: Day 57 (Q28D), Day 71 (Q14D) and Day 78 (Q7D) predose, EOI (IV cohort), 4 hours, 3, 7, 14, 28 days postdose
Area Under the Concentration-time Curve Over the Dosing Interval (AUCtau) for Tezepelumab
The PK parameter AUCtau was estimated based on the serum concentrations of tezepelumab using noncompartmental methods.
The dosing interval (tau) was 28 days, 14 days or 7 days depending on the treatment arm.
The concentration of tezepelumab in human serum was measured using a validated ELISA. The lower limit of quantification of the assay was 10 ng/ml.
Measured: First dose: Day 1 predose, end of infusion (EOI; IV cohort only), 4 hours, 3, 7, 14 (Q14D & Q28D only) and 28 days (Q28D only) postdose. Last Dose: Day 57 (Q28D), Day 71 (Q14D) and Day 78 (Q7D) predose, EOI (IV cohort), 4 hours, 3, 7, 14, 28 days postdose
Accumulation Ratio Based on AUCtau
Accumulation ratio (AR) based on AUCtau was calculated as AUCtau after last dose / AUCtau after first dose, except for the Q7D cohort where AR was calculated as AUCtau after last dose / area under the concentration-time curve from time 0 to time of last measurable concentration (AUC0-t) after first dose.
Measured: First dose: Day 1 predose, end of infusion (EOI; IV cohort only), 4 hours, 3, 7, 14 (Q14D & Q28D only) and 28 days (Q28D only) postdose. Last Dose: Day 57 (Q28D), Day 71 (Q14D) and Day 78 (Q7D) predose, EOI (IV cohort), 4 hours, 3, 7, 14, 28 days postdose
Accumulation Ratio Based on Cmax
Accumulation ratio based on Cmax calculated as Cmax after last dose / Cmax after first dose
Measured: First dose: Day 1 predose, end of infusion (EOI; IV cohort only), 4 hours, 3, 7, 14 (Q14D & Q28D only) and 28 days (Q28D only) postdose. Last Dose: Day 57 (Q28D), Day 71 (Q14D) and Day 78 (Q7D) predose, EOI (IV cohort), 4 hours, 3, 7, 14, 28 days postdose

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Tezepelumab in people with Healthy Volunteers, run by Amgen.
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 9 inclusion and 15 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 21 Sep 2022. Status can change between updates, so confirm with the study contact before making plans.
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 23 May 2022). 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 (time frame: From first dose of study drug up to day 169). The study lists 2 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 NCT00972179, 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 21 Sep 2022.
