About this study

Official title: Phase Ib/II Study of the Glutaminase Inhibitor CB-839 in Combination With Azacitidine in Patients With Advanced Myelodysplastic Syndrome

This phase I/II trial studies the side effects of glutaminase inhibitor CB-839 in combination with azacitidine in treating patients with myelodysplastic syndrome that has spread to other places in the body. Glutaminase inhibitor CB-839 and azacitidine may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine the safety, tolerability and clinical activity of glutaminase inhibitor CB-839 (CB-839) in combination with azacitidine (AZA) for patients with advanced myelodysplastic syndrome (MDS).

SECONDARY OBJECTIVES:

  1. To explore the pharmacokinetics (PK) of CB-839 in combination with AZA. II. To explore the pharmacodynamics (PDn) of CB-839 in combination with AZA. III. To assess overall survival, event-free survival and duration of response of CB-839 in combination with AZA.

OUTLINE:

Patients receive glutaminase inhibitor CB-839 orally (PO) twice daily (BID) on days 1-28 and azacitidine subcutaneously (SC) or intravenously (IV) over 10-40 minutes on days 1-7.

After completion of study treatment, patients are followed up at 28 days.

Being tested
Azacitidine, Glutaminase Inhibitor CB-839
Medical subject headings

What is being measured

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

  1. Number of Participants With a Response

    Response is Complete Remission (CR) + Partial Remission (PR) + Marrow CR = Complete Remission (CR) is </=5% myeloblasts with normal maturation of all cell lines* Persistent dysplasia will be noted, Peripheral blood; hemoglobin>/=11 g/dL, Platelets >/= 100x10^9/L ,Neutrophils >/=1.0 x 10^9/L, Blasts = 0%. Partial Remission (PR) is all CR criteria if abnormal before treatment except: Bone marrow blasts decreased by </=50% over pretreatment but still >5% Cellularity and morphology not relevant. Marrow CR is Bone marrow: </= 5% meyloblasts and decreased by >/= 50% over pretreatment† Peripheral blood: if HI responses, they will be noted in addition to marrow CR.

    Measured: Up to 5 years, 4 months

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Azacitidine and Glutaminase Inhibitor CB-839 in people with Acute Myeloid Leukemia With Multilineage Dysplasia and Blasts 20-30 Percent of Bone Marrow Nucleated Cells, run by M.D. Anderson Cancer Center 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 11 inclusion and 9 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 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 14 May 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 With a Response (time frame: Up to 5 years, 4 months). 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 NCT03047993, 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.
