Trial summary

This phase II trial is studying how well aflibercept works in treating patients with myelodysplastic syndromes. Aflibercept may be able to carry cancer-killing substances directly to myelodysplastic syndrome cells. It may also stop the growth of cancer cells by blocking blood flow to the cancer Read more about this study

About this study

Official title: A Phase II Study of VEGF Trap (NSC 724770) in Patients With MDS

This phase II trial is studying how well aflibercept works in treating patients with myelodysplastic syndromes. Aflibercept may be able to carry cancer-killing substances directly to myelodysplastic syndrome cells. It may also stop the growth of cancer cells by blocking blood flow to the cancer

Read the detailed description

OBJECTIVES:

  1. To determine the antitumor activity of aflibercept as assessed by the hematological response rate.

II. To determine overall and progression-free survival in patients with myelodysplastic syndromes.

III. To assess hematologic improvement and time to leukemic transformation. IV. To assess the toxicity profile of aflibercept in this patient population. V. To perform correlative studies to better understand the ability of aflibercept to reach and modulate its respective targets.

OUTLINE: This is a multicenter study.

Patients will receive aflibercept IV over 1 hour on day 1. Courses repeat every 14 days in the absence of disease progression or unacceptable toxicity.

Blood and bone marrow samples will be obtained periodically for pharmacokinetic and biomarker correlative studies. Pharmacokinetic analysis by ELISA; anti-aflibercept antibody measurements; analysis of VEGF and VEGFR expression; and analysis of gene expression by quantitative PCR will be conducted. The effect of aflibercept on apoptosis and proliferation of CD34+ cells will also be analyzed by flow cytometry based assays.

After completion of study treatment, patients are followed periodically.

What is being measured

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

  1. Hematological Response Rate

    Complete Response (CR): repeat bone marrow (BM) shows <5% myeloblasts, and peripheral blood values lasting ≥ 2 months of hemoglobin (hgb) (>110 g/L), neutrophils (≥1.0x10^9/L), platelets (≥100x10^9/L), blasts (0%) and no dysplasia. Partial Response (PR): same as CR for peripheral blood except BM shows blasts decrease by ≥ 50% but still > 5% or a less advanced FAB classification from pretreatment. Hematological response=CR+PR.

    Measured: Up to 3 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing ziv-aflibercept, laboratory biomarker analysis and pharmacological study in people with Atypical Chronic Myeloid Leukemia, BCR-ABL1 Negative and Chronic Myelomonocytic Leukemia, run by National Cancer Institute (NCI) 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 19 inclusion and 24 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 Jan 2015. 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 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 8 Jan 2015). 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?

Hematological Response Rate (time frame: Up to 3 years). 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 Jan 2015.
