About this study

Background:

Acute myeloid leukemia (AML) is a cancer of the white blood cells. It is fatal if not treated. Treatment for AML that has not responded to treatment (refractory) or has returned after treatment (relapsed) often do not work. Researchers want to see if an immunotherapy drug, combined with a less intense chemotherapy, may be able to help.

Objective:

To test if pembrolizumab, in combination with decitabine, is a possible treatment for people with relapsed or refractory AML.

Eligibility:

Adults 18 years of age and older with refractory AML or relapsed AML.

Design:

Participants will be first screened for eligibility.

The study is counted in 21-day cycles. The initial phase of the study consists of 8 cycles. Participants may be in the study for up to 2 years if they are responding to the treatment.

The first 3 weeks of treatment is usually done in the hospital. The rest may be done as an outpatient.

Participants will get pembrolizumab at the beginning of each cycle through an IV.

Participants will usually get decitabine by IV on days 8 12 and days 15 19 of every other cycle.

Participants will give blood samples.

Participants will have bone marrow exams. A needle will be inserted into the hip to extract cells from the bone marrow.

Some participants may give a sample of saliva from the inside of their cheek.

Some participants may give a small skin sample. The top layer of the skin is removed.

Some patients may require leukapheresis before starting treatment. This is a procedure to remove leukemia cells in the blood stream.

Read the detailed description

This is a pilot study to determine the feasibility of a novel combination of Pembrolizumab and Decitabine in relapsed/refractory adult AML patients. While both Pembrolizumab and Decitabine are FDA approved agents, this study will explore giving these drugs in combination for this population of patients.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PembrolizumabDrug

    Also called Keytruda, MK-3475

    200 mg will be administered as a 30 minute IV infusion every 3 weeks. Every effort should be made to target infusion timing to be as close to 30 minutes as possible. However, given the variability of infusion pumps, a window of -5 minutes and +10 minutes is permitted (i.e., infusion time is 30 minutes: -5 min/+10 min).

  • DecitabineDrug

    Also called Dacogen

    Will be administered at a dose of 20 mg/m^2 by continuous intravenous infusion over 1 hour repeated daily ordinarily on days 8 through 12 and 15 through 19 of alternative cycles (ie: cycles 1, 3, 5, 7). Decitabine should be repeated every 6 weeks.

What is being measured

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

  1. Feasibility of a Novel Combination of Pembrolizumab and Decitabine in Relapsed/Refractory Acute Myeloid Leukemia Participants

    The number of patients who could be treated with a novel combination of Pembrolizumab and Decitabine in relapsed/refractory Acute Myeloid Leukemia participants without being removed from the protocol due to treatment related toxicities.

    Measured: 24 weeks

Secondary outcomes (5)

  1. Median Days to First Response From Start of Study to Initial Achievement of First Response (mCR, mCRi, CR, CRi, PR, or SD)

    Time to first response (days) is time from start of study to first response (mCR, mCRi, CR, CRi, PR, or SD) in relapsed/refractory acute myeloid leukemia (AML) participants.

    Measurable residual disease (MRD) negative complete remission is no evidence of residual disease, < 5% blasts, no Auer rods and may be with mCR or without count recovery (ANC ≥ 1,000/mcl and platelet count ≥ 100,000/mcl) as mCRi. Morphologic complete remission (CR) is ANC ≥ 1,000/mcl, platelet count ≥ 100,000/mcl, < 5% blasts, no Auer rods, no evidence of disease; Morphologic complete remission with incomplete blood count recovery (CRi) is same as CR but ANC may be < 1,000/mcl and/or platelet count < 100,000/mcl; Partial remission (PR) is ANC ≥ 1,000/mcl, platelet count > 100,000/mcl, and at least a 50% decrease in the percentage of marrow aspirate blasts to 5-25%, or marrow blasts < 5% with persistent Auer rods. Stable disease (SD) is absence of a complete or partial response, and no progressive disease.

    Measured: At the end of each cycle 2 (week 6), 4 (week 12), 6 (week 18), 8 (up to week 24)

  2. Median Days to Best Response From Start of Study to Initial Achievement of Best Response (by the Order of mCR, mCRi, CR, CRi, PR, or SD)

    Time to Best Response is defined as time (days) from start of study to initial achievement of best response. Best response is defined by the order of mCR, mCRi, CR, CRi, PR, or SD. Measurable residual disease (MRD) negative complete remission is no evidence of residual disease, < 5% blasts, no Auer rods and may be with mCR or without count recovery (ANC ≥ 1,000/mcl and platelet count ≥ 100,000/mcl) as mCRi. Morphologic complete remission (CR) is ANC ≥ 1,000/mcl, platelet count ≥ 100,000/mcl, < 5% blasts, no Auer rods, no evidence of disease; Morphologic complete remission with incomplete blood count recovery (CRi) is same as CR but ANC may be < 1,000/mcl and/or platelet count < 100,000/mcl; Partial remission (PR) is ANC ≥ 1,000/mcl, platelet count > 100,000/mcl, and at least a 50% decrease in the percentage of marrow aspirate blasts to 5-25%, or marrow blasts < 5% with persistent Auer rods. Stable disease (SD) is absence of a complete or partial response, and no progressive disease.

    Measured: At the end of each cycle 2 (week 6), 4 (week 12), 6 (week 18), 8 (up to week 24)

  3. Median Duration (Days) of Response From Initial Achievement of Response to Loss of Response (mCR, mCRi, CR, CRi, PR, or SD)

    To determine duration (days) of response as defined as time from initial achievement of response to loss of response (mCR, mCRi, CR, CRi, PR, or SD).

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Pembrolizumab and Decitabine in people with Relapsed Acute Myeloid Leukemia, run by National Heart, Lung, and Blood Institute (NHLBI) at 1 site 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 18 inclusion and 27 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 28 Dec 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 21 May 2020). 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?

Feasibility of a Novel Combination of Pembrolizumab and Decitabine in Relapsed/Refractory Acute Myeloid Leukemia Participants (time frame: 24 weeks). 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 NCT02996474, 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 28 Dec 2022.
