About this study

Official title: A Phase I Study of Metformin and Cytarabine for the Treatment of Relapsed/Refractory Acute Myeloid Leukemia

The purpose of the study is to determine if metformin in combination with cytarabine is safe and effective. Participants in this research study have acute myeloid leukemia (AML) that has come back after initial treatment or has not gone away with initial therapy.There is evidence that metformin directly kills leukemia cells. Laboratory data have also shown that combinations of metformin with cytarabine are more efficient than each agent alone in killing leukemia cells in the laboratory.

Read the detailed description

PRIMARY OBJECTIVES:

  1. Determine the maximum tolerated dose (MTD) of metformin (metformin hydrochloride) in combination with cytarabine in relapsed/refractory AML.

II. Define the dose limiting toxicity (DLT) of metformin in combination with cytarabine in relapsed/refractory AML.

SECONDARY OBJECTIVES:

  1. Remission rate. II. Overall survival (OS). III. Disease-free survival (DFS). IV. Length of remission.

OUTLINE: This is a dose-escalation study of metformin hydrochloride in combination with Cytarabine.

Patients receive metformin hydrochloride orally (PO) twice daily (BID) on days 1-15 and cytarabine intravenously (IV) over 3 hours BID on days 4-10.

After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 5 years.

What is being measured

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

  1. Evaluate Toxicity by Assessing the Adverse Events of Metformin and Cytarabine

    To determine the maximum tolerated dose (MTD) by assessing the adverse events of metformin in combination with cytarabine in evaluating toxicity. Assessments will occur daily during cytarabine administration and at least twice weekly following treatment until blood count recovery.

    Measured: Checked daily during administration of cytarabine and at least 2x weekly following therapy until desired blood counts acheived (maximum 15 days)

  2. Study Treatment Dose Toxicity Will be Evaluated by Measurement of Adverse Events Experienced While on Treatment

    Determination of Dose Limiting Toxicity (DLT) as evidenced by adverse events due to toxicity from study treatment. If no DLT is observed, then 3 patients will be enrolled in the next dose escalated cohort. If one DLT is seen in the first 3 patients, then an additional 3 patients will be enrolled at the same dose cohort. If 0-1 in 6 patients experience a DLT this dose will be considered tolerable and the next dose escalated cohort with enroll 3 patients. If 2 or more in 6 patients experience a DLT, the maximum tolerated dose (MTD) will have been exceeded and the next cohort will enroll 3 patients at a reduced dose.

    Measured: Checked daily during administration of cytarabine and at least 2x weekly following therapy until desired blood counts acheived (maximum 15 days)

Secondary outcomes (4)
  1. Remission Rate

    Patients will be evaluated for remission status in response to therapy.

    Measured: Every 3 months for 2 years, and then every 6 months for 5 years post-treatment

  2. Overall Survival

    Patients will be followed-up with from the initiation of study treatment until progression of disease or for up to 5 years, whichever comes first.

    Measured: Every 3 months for 2 years, and then every 6 months for 5 years post-treatment

  3. Disease-free Survival

    Evaluation of Disease-Free Survival will defined as the time from the initiation of study treatment until the time of disease relapse.

    Measured: Every 3 months for 2 years, and then every 6 months for 5 years post-treatment

  4. Length of Remission

    Patients will be followed-up with to determine Remission length which is defined as the time from attainment of remission to relapse of disease.

    Measured: From date of remission of disease to date of relapse (maximum of 5 year follow-up)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing metformin hydrochloride, cytarabine and laboratory biomarker analysis in people with Adult Acute Megakaryoblastic Leukemia (M7) and Adult Acute Minimally Differentiated Myeloid Leukemia (M0), run by Northwestern University 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 20 inclusion and 8 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 31 Jan 2019. 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 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 13 Nov 2018). 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?

Evaluate Toxicity by Assessing the Adverse Events of Metformin and Cytarabine (time frame: Checked daily during administration of cytarabine and at least 2x weekly following therapy until desired blood counts acheived (maximum 15 days)). 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?
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 31 Jan 2019.
