Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 15 years and older
- All sexes
- No healthy volunteers
- Child, Adult, Older adult
Who may be able to join
- Patients with relapsed or refractory AML (including refractory anemia with excess of blasts [RAEB], refractory anemia with excess of blasts in transition to AML [RAEBT], or untreated AML when standard chemotherapy is not considered appropriate or is refused, CML in blastic phase, and agnogenic myeloid metaplasia (AMM)
- Age 15 years or greater (separate pediatric studies will be conducted if results of adult studies are considered sufficiently positive)
- Laboratory values less than or equal to 2 weeks prior to study entry - Serum bilirubin 1.5mg/dL, unless considered due to organ leukemic involvement or Gilbert's syndrome. - SGOT or SGPT less than or equal to 2.5 x upper limit of normal. - Serum creatinine less than or equal to 2mg/dL,

- The effects of PTK 787 and imatinib on the developing human fetus are unknown. For this reason and because inhibitors of mRNA translation are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (barrier method of birth control; abstinence) for the duration of study participation.
- Due to possible interactions with study drugs, oral contraceptives should not be used. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.

- Ability to understand and the willingness to sign a written informed consent document.
- Performance Status less than or equal to 2.

- Prior therapy with anti-VEGF agents.
- Concomitant administration of anticancer drugs is not permitted, except for hydroxyurea. Leukopheresis is allowed within the first 28 days of treatment if required to control elevated blast levels or platelet counts. Within the first 28 days of treatment, hydroxyurea may be given at a maximum dose of 5 g daily for up to a total of 7 days. For leukopheresis, a maximum of 2 procedures per week or 4 procedures during the first 28 days is allowed.

- Uncontrolled intercurrent illness including, but not limited to, uncontrolled diabetes, interstitial pneumonia or extensive and symptomatic interstitial fibrosis of the lung, chronic liver disease or psychiatric illness/social situations that would limit compliance with study requirements.

- Patients with confirmed diagnosis of human immunodeficiency virus (HIV) infection are excluded - A separate study for patients with HIV will be performed if indicated.
- Pregnant women are excluded from this study because PTK 787 and imatinib may have a potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with PTK 787 or imatinib, breastfeeding patients will not be eligible.

About this study
Official title: Ph I/II Study of PTK 787 (Vatalanib) and Gleevec (Imatinib) in Patients With Refractory Acute Myelogenous Leukemia (AML), Agnogenic Myeloid Metaplasia (AMM), and Chronic Myelogenous Leukemia- Blastic Phase (CML-BP)
The goal of this clinical research study is to find the highest safe doses of PTK 787 (vatalanib) and Gleevec (imatinib mesylate) that can be given to treat Chronic Myelogenous Leukemia-Blastic Phase (CML-BP), Refractory Acute Myelogenous Leukemia (AML), or Agnogenic Myeloid Metaplasia (AMM). Another goal is to see how effective this combination treatment is.
Read the detailed description
Rationale: The purpose of this study is to combine PTK-787, a potent orally vascular endothelial growth factor (VEGF) receptor inhibitor (in disorders where VEGF is known to be involved in the pathophysiology), with Imatinib mesylate (IM), a protein-tyrosine kinase inhibitor of abl, Bcr-Abl, platelet derived growth factor (PDGF), and c-Kit (in same disorders where these kinases are believed to be important). The potential synergy between oral agents that inhibit these kinases in disorders where each of the two agents have some, but inadequate, single agent activity is being studied in this protocol. We will also have an opportunity to assess if there is any correlation between response and individual kinase mutations e.g., c-Kit in patients with AML. If improved outcomes are observed, further studies will be indicated to investigate which, if either, agent is predominantly responsible for such a benefit - these studies will be facilitated by the availability of more potent e.g., (AMN107 as an abl inhibitor), (Bevacizumab, AG013736 as VEGF inhibitors) agents which will help to define the relative importance of the various inhibitory activities.
Objectives: To determine the maximum tolerated doses (MTD) and pharmacokinetics (PK) of PTK 787 and imatinib mesylate, when given in combination to patients with refractory acute myelogenous leukemia (AML), agnogenic myeloid metaplasia (AMM) and chronic myelogenous leukemia in blastic phase (CML-BP).
To determine the efficacy (response rate, survival, time to progression, time to treatment failure, duration of response) of the MTD in these study populations.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Imatinib Mesylate (Gleevec) and PTK 787 (vatalanib) in people with Acute Myelogenous Leukemia and Agnogenic Myeloid Metaplasia, 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 8 inclusion and 16 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 20 Jan 2012. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Time to Response (time frame: 28 days). 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 20 Jan 2012.
