Trial Information

Phase I-II Study of Idarubicin, Cytarabine, and Sorafenib (BAY43-9006), an Oral VEGF, RAF and FLT3 Inhibitor, in Patients With High-risk MDS and AML

The Study Drugs:

Sorafenib is designed to block the function of important proteins in cancer cells. When
active, these proteins help cause abnormal growth and behavior of leukemia cells.

Idarubicin and Ara-C are both designed to insert themselves into DNA (the genetic material
of cells) and to stop DNA from repairing itself.

Study Groups:

If you are found to be eligible to take part in this study, you will be assigned to a study
group based on when you join this study.

If you are enrolled in the Phase I part of this study, the dose of sorafenib you receive
with Ara-C and idarubicin will depend on when you enrolled in this study. Each new group of
3 participants will receive a higher dose level of sorafenib than the previous group until
the highest safe dose of sorafenib that can be given in combination with Ara-C and
idarubicin is reached.

If you are enrolled in the Phase II portion of this study, you will receive the highest safe
dose of sorafenib in combination with Ara-C and idarubicin found in the Phase I part.

Study Drug Administration:

During the study, you will receive treatment over 28-day "cycles." The doses of idarubicin
and Ara-C are the same for all study participants.

On Days 1-4 (Days 1-3 if you are older than 60) of each induction cycle (#1 and possibly
#2), you will receive Ara-C through a nonstop infusion (through a needle in your vein). You
will also receive steroids by mouth or through a vein every day to reduce the risks of side
effects, such as rash.

On Days 1-3 of each induction cycle (#1 and possibly #2), you will receive idarubicin by
vein over 1 hour once a day.

In general, sorafenib will be taken by mouth twice daily on Days 1-7, unless otherwise
instructed. However, the dose of sorafenib may differ among study participants. Sorafenib
should be taken with water on an empty stomach. Your study doctor will give you complete
instructions on when and how to take sorafenib.

Depending on the side effects that you may have, the dose of sorafenib may be decreased,
stopped until side effects go away, or even stopped completely, if your doctor thinks that
this is in your best interest.

Study Visits:

During Cycles 1-2, you will have study visits about 2 times a week. You may need to have
study visits more often when the study doctor thinks it is necessary. At these visits, you
will have the following procedures performed.

- You will be asked about any side effects you may have experienced and any medications
you may be taking.

- Blood (about 2 teaspoons) will be drawn for routine tests.

During Cycles 1 and 2, between Days 21-28, you will have a bone marrow aspirate and/or
biopsy performed to check the status of the disease.

For Cycle 3 and in further cycles, you will have a bone marrow aspirate as determined
necessary by your doctor. If your doctor thinks you have responded to the treatment, you
will then have bone marrow aspirates collected every 3-6 months, if your doctor feels this
to be necessary.

Consolidation Therapy:

If it is found that the disease is responding to treatment, you may receive 5 additional
cycles of therapy. These cycles are called "consolidation" therapy and will be given every
4-6 weeks.

On Days 1-3, Ara-C will be given as a nonstop infusion. You will also receive steroids
either by mouth or by vein to help reduce the risk of side effects.

On Days 1-2, idarubicin will be given by vein over 1 hour.

Sorafenib will be taken twice daily by mouth for 7 or more days, at a schedule determined by
your study doctor.

After each cycle, about every 4-6 weeks, blood (about 2 teaspoons) will be drawn to check
your blood count levels.

Maintenance Therapy:

After 5 cycles of consolidation therapy, and according to your response to consolidation
therapy, you may continue on this study to receive "maintenance" treatment, as needed, and
as determined by your study doctor for up to 7 more cycles.

You will take sorafenib twice a day every day during the 28-day cycle.

Every 1-4 weeks, blood (about 2 teaspoons) will be drawn for routine tests.

Length of Study:

You may receive up to 14 cycles in total of therapy. You may be taken off this study if the
leukemia gets worse, develop another illness that interferes with taking the study drugs, or
you have intolerable side effects.

This is an investigational study. Sorafenib is FDA approved and commercially available for
the treatment of metastatic renal cancer only. Idarubicin is FDA approved for use in
combination with other approved antileukemic drugs for the treatment of acute myeloid
leukemia (AML) in adults. Cytarabine is FDA approved for use in the treatment of leukemia.
The use of sorafenib combined with idarubicin and Ara-C in the treatment of AML and
high-risk MDS is investigational and authorized for use in research only. Up to 75
patients will take part in this study. All patients will be enrolled at M. D. Anderson
Cancer Center.

Inclusion Criteria:

1. Diagnosis of 1) AML (World Health Organization classification definition of > 20%
blasts), or 2) high risk MDS (defined as the presence of > 10% blasts).

2. Patients aged 15 to 60 years are eligible. Patients older than 60 who are deemed fit
to receive intensive chemotherapy by the treating physician are eligible after
discussion with the Principal Investigator (PI). For the Phase II portion of the
study, patients must be chemo-naïve, i.e. not have received any prior chemotherapy
(except hydrea) for AML or MDS. They could have received hypomethylator agents,
transfusions, hematopoietic growth factors or vitamins. Temporary prior measures such
as pheresis or hydrea are allowed. In the Phase I portion, patients with relapsed or
refractory AML/MDS are also eligible.

3. Serum biochemical values with the following limits unless considered due to leukemia:
1) creatinine less than or equal to 2 mg/dl, 2) total bilirubin less than or equal to
2 mg/dL, unless increase is due to hemolysis or congenital disorder, and 3)
transaminases (SG PT) less than or equal to 2.5 times ULN

4. Ability to take oral medication.

5. Ability to understand and provide signed informed consent.

6. Baseline test of ejection fraction must be >/=50%.

7. Performance status < 3, unless directly related to the disease process as determined
by the principal investigator.

Exclusion Criteria:

1. Patients with Acute promyelocytic leukemia (APL).

2. Any coexisting medical condition that in the judgment of the treating physician is
likely to interfere with study procedures or results.

3. Nursing women, women of childbearing potential with positive urine pregnancy test, or
women of childbearing potential who are not willing to maintain adequate
contraception (such as birth control pills, IUD, diaphragm, abstinence, or condoms by
their partner) over the entire course of the study.
