Study start date: July 1, 2004Actual date on which the first participant was enrolled.

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. 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.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
9 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How participants are assigned to different groups/arms
In this clinical study, all participants receive the same treatment. Since there is only one group, there is no need for randomization or assignment to different arms. This type of study is often used to test a new treatment without comparing it to another.

Other Ways to Assign Participants
Randomized allocation: Participants are assigned randomly, like flipping a coin, to ensure fairness and reduce bias.
Non-randomized allocation: Participants are assigned based on specific factors, such as their medical condition or a doctor's decision.

How treatments are given to participants
In this study, all participants receive the same treatment. This approach is often used to evaluate the effects of a single intervention without comparing it to another.

Other Ways to Assign Treatments
Parallel assignment: Participants are split into separate groups, each receiving a different treatment.
Cross-over assignment: Participants switch between treatments during the study.
Factorial assignment: Participants receive different combinations of treatments.
Sequential assignment: Participants receive treatments one after another in a specific order, possibly based on individual responses.
Other assignment: Treatment assignment does not follow a standard or predefined design.

How the effectiveness of the treatment is controlled
In a non placebo-controlled study, no participants receive an inert substance (placebo) to compare outcomes. Instead, all participants receive either the experimental treatment or an alternative treatment (often the Standard of Care). This method allows researchers to compare the effects of the experimental treatment with those of a different active intervention, rather than a placebo.

Other Options
Placebo-Controlled: A placebo is used to compare the effects of the experimental treatment with those of an inert substance, isolating the true treatment effect.

How the interventions assigned to participants is kept confidential
Everyone involved in the study knows which treatment is being given. This is typically used when it's not possible or necessary to hide the treatment details from participants or researchers.

Other Ways to Mask Information
Single-blind: Participants do not know which treatment they are receiving, but researchers do.
Double-blind: Neither participants nor researchers know which treatment is given.
Triple-blind: Participants, researchers, and outcome assessors do not know which treatment is given.
Quadruple-blind: Participants, researchers, outcome assessors, and care providers all do not know which treatment is given.

Negative for proteinuria based on dip stick reading OR, if documentation of +1 result for protein on dip stick reading, then total urinary protein less than or equal to 500 mg and measured creatinine clearance (CrCl) greater than or equal to 50 mL/min from a 24-hour urine collection

16 exclusion criteria prevent from participating
Patients who have had cytotoxic chemotherapy, except for hydroxyurea, or radiotherapy within 7 days prior to entering the study. Patients will have cleared all toxicities from prior therapies before starting this study combination
Patients who have received investigational drugs less than or equal to 2 weeks prior to study entry
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

Treatment Groups
Study Objectives
2 intervention groups 

are designated in this study

This study does not include a placebo group 

Treatment Groups
Group I
Experimental
For 1 week prior to receipt of study combination regimen, all patients will receive single agent PTK 787 at dose specified for that dose level of the study combination regimen to allow stabilization of PTK 787 levels. Patients should not have a grade 3 or 4 PTK 787-related adverse events in order to begin study combination therapy with a imatinib on day 8. On Day 8, PTK 787 250 mg by mouth every day and imatinib 600 mg by mouth every day (for Acute Myelogenous Leukemia (AML), Chronic Myelogenous Leukemia- blastic phase (CML-BP) and imatinib 400 mg by mouth every day (for Agnogenic Myeloid Metaplasia (AMM). Length of therapy is four courses; each course equals 28 days. Patients assessed for response after each course.
Group II
Experimental
For 1 week prior to receipt of study combination regimen, all patients will receive single agent PTK 787 at dose specified for that dose level of the study combination regimen to allow stabilization of PTK 787 levels. Patients should not have a grade 3 or 4 PTK 787-related adverse events in order to begin study combination therapy with a imatinib on day 8. PTK 787 250 mg by mouth for Days 1 - 7.
