What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants Who Experienced a Dose Limiting Toxicity (DLT)
A DLT was assessed by the Common Terminology Criteria for Adverse Events (CTCAE) v 4.0, and considered by the investigators to be related to AMG 176. A DLT was defined as a grade 3 or higher non-hematological or a grade 4 hematologic adverse event (AE) that occurred during the DLT observation period.
CTCAE is graded from grade 1 to 5, with higher grades indicating a worse outcome, and included; grade 1 = mild, grade 2= moderate, grade 3 = severe, grade 4 = life-threatening, and grade 5 = death.
Measured: Days 1 to 28 of cycle 1 (4 weeks)
Number of Participants Who Experienced Treatment-emergent Adverse Events (TEAEs)
An AE was defined as any untoward medical occurrence in a clinical trial participant.
A TEAE was an AE that started on or after the first dose of investigational product (AMG 176) up to 30 days after the end of investigational product. Any clinically significant changes in vital signs, electrocardiograms, and clinical laboratory tests were reported as TEAEs.
A treatment-related AE was any TEAE that per investigator review had a reasonable possibility of being caused by the investigational product (AMG 176).
Measured: Day 1 cycle 1 to 30 days after the last dose of AMG 176; median treatment duration was 1.2 months
Maximum Observed Concentration (Cmax) of AMG 176
Plasma concentrations of AMG 176 were determined using a validated assay. Noncompartmental analysis was performed for estimation of pharmacokinetic (PK) parameters. Concentrations below the lower limit of quantification (LLOQ) of 5.00 ng/mL were set to zero before data analysis.
Measured: Parts 1B, 3B, 3C, 3A (cohort 4) Cycle 1: day 1 pre, end of infusion (EOI), 1, 2, 3, 5, 7 hrs EOI, day 8 pre, EOI; Part 3D also days 9, 15 pre and EOI; Parts 1A, 3 (except cohort 4), 4: also day 2 pre, EOI, 1, 2, 3, 5, 7 hrs EOI, day 9 pre and EOI

Plasma concentrations of AMG 176 were determined using a validated assay. Noncompartmental analysis was performed for estimation of PK parameters. Concentrations below the LLOQ of 5.00 ng/mL were set to zero before data analysis.
Measured: Parts 1A, 3A and, 4: Cycle 1 day 1 pre, EOI, 1, 2, 3, 5, and 7 hrs EOI, cycle 1 day 8 pre and EOI

Plasma concentrations of AMG 176 were determined using a validated assay. Noncompartmental analysis was performed for estimation of PK parameters. Concentrations below the LLOQ of 5.00 ng/mL were set to zero before data analysis.
Measured: Parts 1A, 3A, and 4: Cycle 1 day 2 pre, EOI, 1, 2, 3, 5, and 7 hrs EOI, cycle 1 day 9 pre and EOI
AUC From Time 0 to 168 Hours (AUC0-168) of AMG 176 (Parts 1B, 3 [Cohort 4], 3B, 3C, and 3D)
Plasma concentrations of AMG 176 were determined using a validated assay. Noncompartmental analysis was performed for estimation of PK parameters. Concentrations below the LLOQ of 5.00 ng/mL were set to zero before data analysis.
Measured: Parts 1B, 3B, 3C, and 3 (cohort 4): Cycle 1 day 1 pre, EOI, 1, 2, 3, 5, and 7 hrs EOI, cycle 1 day 8 pre, EOI; Part 3d also cycle 1 day 15 pre and EOI
Clearance (CL) of AMG 176
Plasma concentrations of AMG 176 were determined using a validated assay. Noncompartmental analysis was performed for estimation of PK parameters. Concentrations below the LLOQ of 5.00 ng/mL were set to zero before data analysis. Clearance was calculated as Dose/ AUC0-144 for Parts 1A, 3A, and 4; and as Dose/AUC0-168 for Parts 1B, 3 (Cohort 4 only) 3B, 3C, and 3D.
Measured: Parts 1B, 3B, 3C, 3A (cohort 4) Cycle 1: day 1 pre, EOI, 1, 2, 3, 5, 7 hrs EOI, day 8 pre, EOI; Part 3D also days 9, 15 pre and EOI; Parts 1A, 3 (except cohort 4), 4: also day 2 pre, EOI, 1, 2, 3, 5, 7 hrs EOI, day 9 pre and EOI

Plasma concentrations of AMG 176 were determined using a validated assay. Noncompartmental analysis was performed for estimation of PK parameters. Concentrations below the LLOQ of 5.00 ng/mL were set to zero before data analysis.

Time frame: Parts 1B, 3B, 3C, and 3 (cohort 4): Cycle 1 day 1 pre, EOI, 1, 2, 3, 5, and 7 hrs EOI, cycle 1 day 8 pre, EOI; Part 3d also cycle 1 day 15 pre and EOI
Plasma concentrations of AMG 176 were determined using a validated assay. Noncompartmental analysis was performed for estimation of PK parameters. Concentrations below the LLOQ of 5.00 ng/mL were set to zero before data analysis.
Clearance (CL) of AMG 176
Time frame: Parts 1B, 3B, 3C, 3A (cohort 4) Cycle 1: day 1 pre, EOI, 1, 2, 3, 5, 7 hrs EOI, day 8 pre, EOI; Part 3D also days 9, 15 pre and EOI; Parts 1A, 3 (except cohort 4), 4: also day 2 pre, EOI, 1, 2, 3, 5, 7 hrs EOI, day 9 pre and EOI
Plasma concentrations of AMG 176 were determined using a validated assay. Noncompartmental analysis was performed for estimation of PK parameters. Concentrations below the LLOQ of 5.00 ng/mL were set to zero before data analysis. Clearance was calculated as Dose/ AUC0-144 for Parts 1A, 3A, and 4; and as Dose/AUC0-168 for Parts 1B, 3 (Cohort 4 only) 3B, 3C, and 3D.
Terminal Half-life (t1/2) of AMG 176
Time frame: Parts 1B, 3B, 3C, 3A (cohort 4) Cycle 1: day 1 pre, EOI, 1, 2, 3, 5, 7 hrs EOI, day 8 pre, EOI; Part 3D also days 9, 15 pre and EOI; Parts 1A, 3 (except cohort 4), 4: also day 2 pre, EOI, 1, 2, 3, 5, 7 hrs EOI, day 9 pre and EOI
Plasma concentrations of AMG 176 were determined using a validated assay. Noncompartmental analysis was performed for estimation of PK parameters. Concentrations below the LLOQ of 5.00 ng/mL were set to zero before data analysis.

Best Overall Response According to the 2017 European LeukemiaNet (ELN) Criteria in AML Participants (Parts 3A, 3B, 3C, 3D, and 4)
Time frame: Day 1 cycle 1 to end of study; median duration from start of study treatment to end of study for all participants was 2.2 months

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing AMG 176, Azacitidine and Itraconazole in people with Relapsed or Refractory Multiple Myeloma and Relapsed or Refractory Acute Myeloid Leukemia, run by Amgen at 24 sites in 5 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 14 inclusion and 16 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 9 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 24 sites in United States, Japan, Germany, Australia, Canada. 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?
Yes. Results are posted in the registry (first posted 9 Jul 2025). 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 a Dose Limiting Toxicity (DLT) (time frame: Days 1 to 28 of cycle 1 (4 weeks)). The study lists 8 primary outcomes in all. 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 9 Jul 2025; AzTrials last refreshed its copy on 6 Nov 2026.
