About this study

Official title: A Phase 1b Study Assessing Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Efficacy of AMG 330 cIV in Combination With Pembrolizumab in Adult Subjects With Relapsed or Refractory Acute Myeloid Leukemia

The primary objective of this study is to evaluate the safety and tolerability of AMG 330, administered in combination with pembrolizumab, in participants with relapsed or refractory acute myeloid leukemia (R/R AML).

Read the detailed description

This study will assess the safety and tolerability of AMG 330 in combination with pembrolizumab and whether pembrolizumab will enhance the anti-AML activity of AMG 330.

What is being measured

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

  1. Number of Participants Who Experienced Dose-limiting Toxicities (DLTs)

    A DLT was defined as any of the events described below occurring in a participant during the DLT window, unless clearly attributable to causes other than investigational product:

    Any treatment-related death, Grade 4 neutropenia, Grade 3-4 non hematologic toxicity not clearly resulting from the underlying leukemia, with some exceptions, cytokine release syndrome, and any Grade 5 toxicity.

    Measured: 28 days

  2. Number of Participants Who Experienced Treatment-emergent Adverse Events (TEAEs)

    A TEAE was defined as any untoward medical occurrence in a clinical study participant irrespective of a causal relationship with the study treatment that occurred after first dose. Any clinically significant changes in vital signs, electrocardiograms (ECGs), and clinical laboratory tests that occurred after first dose were recorded as TEAEs.

    Measured: From first dose of study treatment until 30 days after last dose, or end of study, whichever was earlier; median (min, max) duration was 0.79 (0.79, 0.79) months.

  3. Number of Participants Who Experienced Treatment-related Adverse Events (TRAEs)

    A TRAE was defined as any untoward medical occurrence in a clinical study participant considered to have a possible causal relationship with the study treatment. Any clinically significant changes in vital signs, electrocardiograms (ECGs), and clinical laboratory tests that were considered to have a possible causal relationship with the study treatment were recorded as TRAEs.

    Measured: From first dose of study treatment until 30 days after last dose, or end of study, whichever was earlier; median (min, max) duration was 0.79 (0.79, 0.79) months.

Secondary outcomes (12)
  1. Complete Remission Without Minimal Residual Disease (CRMRD-)

    CRMRD- was measured according to the 2017 European Leukemia Net (ELN) criteria (Döhner et al, 2017). CRMRD- was defined as complete remission (CR) with negativity for a genetic marker by quantitative reverse transcription polymerase chain reaction (RT-qPCR), or CR with negativity by multiparametric flow cytometry (MFC). CR was defined as bone marrow blasts <5%; absence of circulating blasts and blasts with Auer rods; absence of extramedullary disease; absolute neutrophil count (ANC) ≥ 1.0 x 109/L (1000/μL); platelet count ≥ 100 x 109/L (100 000/μL).

    Measured: From first dose of study treatment until 30 days after last dose, or end of study, whichever was earlier; median (min, max) duration was 0.79 (0.79, 0.79) months.

  2. Complete Remission (CR)

    CR was measured according to the 2017 European Leukemia Net (ELN) criteria (Döhner et al, 2017). CR was defined as bone marrow blasts <5%; absence of circulating blasts and blasts with Auer rods; absence of extramedullary disease; absolute neutrophil count (ANC) ≥ 1.0 x 109/L (1000/μL); platelet count ≥ 100 x 109/L (100 000/μL).

    Measured: From first dose of study treatment until 30 days after last dose, or end of study, whichever was earlier; median (min, max) duration was 0.79 (0.79, 0.79) months.

  3. CR With Incomplete Recovery (CRi)

    CRi was measured according to the 2017 European Leukemia Net (ELN) criteria (Döhner et al, 2017). CRi was defined as all CR criteria (bone marrow blasts <5%; absence of circulating blasts and blasts with Auer rods; absence of extramedullary disease; absolute neutrophil count (ANC) ≥ 1.0 x 109/L (1000/μL); platelet count ≥ 100 x 109/L [100 000/μL]), except for residual neutropenia (< 1.0 x 109/L [1000/μL]) or thrombocytopenia (< 100 x 109/L [100 000/μL]).

    Measured: From first dose of study treatment until 30 days after last dose, or end of study, whichever was earlier; median (min, max) duration was 0.79 (0.79, 0.79) months.

  4. Morphological Leukemia-free State (MLFS)

    MLFS was measured according to the 2017 European Leukemia Net (ELN) criteria (Döhner et al, 2017). MLFS was defined as bone marrow blasts < 5%; absence of blasts with Auer rods; absence of extramedullary disease; no hematologic recovery required.

    Measured: From first dose of study treatment until 30 days after last dose, or end of study, whichever was earlier; median (min, max) duration was 0.79 (0.79, 0.79) months.

  5. Partial Remission (PR)

    PR was measured according to the 2017 European Leukemia Net (ELN) criteria (Döhner et al, 2017). PR was defined as all hematologic criteria of CR; decrease of bone marrow blast percentage to 5 to 25%; and decrease of pre-treatment bone marrow blast percentage by at least 50%.

    Measured: From first dose of study treatment until 30 days after last dose, or end of study, whichever was earlier; median (min, max) duration was 0.79 (0.79, 0.79) months.

  6. Duration of Response (DoR)

    DoR was calculated for participants who achieved overall response (CRMRD-, CR, CRi, PR or MLFS). DoR was defined as time from the first observation indicating an objective response to the subsequent date of disease progression or death, whichever is earlier.

    Measured: From first dose of study treatment until 30 days after last dose, or end of study, whichever was earlier; median (min, max) duration was 0.79 (0.79, 0.79) months.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing AMG 330 and Pembrolizumab in people with Relapsed or Refractory Acute Myeloid Leukemia, run by Amgen 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 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: stopped early, as of the sponsor's last update on 8 Mar 2024. 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 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 8 Mar 2024). 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 Dose-limiting Toxicities (DLTs) (time frame: 28 days). The study lists 3 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 8 Mar 2024.
