About this study
Official title: Phase I/II Study of Sorafenib and 5-Azacitidine for the Treatment of Patients With Refractory or Relapsed Acute Leukemia and Myelodysplastic Syndrome (MDS) - (VZ-MDS-PI-0227)
The goal of this clinical research study is to learn if 5-azacitidine and sorafenib can control the disease in patients with AML or MDS. The safety of this drug combination will also be studied.
Read the detailed description
The Study Drugs:
Sorafenib is designed to block the function of important proteins in cancer cells. These proteins, when active, are partly responsible for the abnormal growth and behavior of cancer cells.
5-Azacytidine is designed to activate ("turn on") certain genes in cancer cells whose job is to fight tumors.
Study Drug Administration:
If you are found to be eligible to take part in this study, you will receive 5-azacytidine either under the skin or by vein on Days 1-7 of each 28-day cycle. If by vein, the infusion will take about 10-40 minutes.
You will take sorafenib by mouth 2 times a day about 12 hours apart, with water on empty stomach, every day.
Each study cycle may last a little longer than 28 days, depending on how you are doing.
Study Visits:
Every week, blood (about 1 tablespoon) will be drawn for routine tests.
Every week for the first 6 weeks, and then as often as your doctor thinks it is needed, you will have your blood pressure measured.
Before each cycle:
- Your performance status will be recorded.
- You will have a physical exam, including measurement of your blood pressure and weight.
Before every 2-4 cycles, you will have a bone marrow aspirate to check the status of the disease.
Length of Study:
You may continue taking the study drugs for as long as the doctor thinks it is in your best interest. You will no longer be able to take the study drugs if the disease gets worse or intolerable side effects occur.
Your participation on the study will be over once you have completed the end-of-treatment and follow-up visits.
End of Study Drug Administration Visit:
After you have stopped taking the study drugs, the following tests and procedures will be performed:
- Your medical history will be recorded.
- Your performance status will be recorded.
- You will have a physical exam, including measurement of your blood pressure and weight.
- You will have a bone marrow aspirate collected to check the status of disease.
This is an investigational study. Sorafenib is FDA approved and commercially available for kidney cancer and liver cancer. 5-Azacitidine is FDA approved for the treatment of MDS, but its combination with sorafenib is investigational.
Up to 60 patients will take part in this study. All will be enrolled at MD Anderson.

Also called 5-aza, Vidaza, 5-AZC, AZA-CR
75 mg/m^2 subcutaneously (SQ) or by vein (IV) daily for 7 days per 28 day cycle.
SorafenibDrug
Also called Nexavar, BAY43-9006

| Study group | Role | What they receive |
|---|---|---|
| Azacitidine + Sorafenib | Experimental | Azacitidine (AZA) 75 mg/m^2 subcutaneously (SQ) or intravenously (IV) daily for 7 days; Sorafenib 200 mg orally twice a day. Receives: Drug: Azacitidine; Drug: Sorafenib |
What is being measured
The primary outcome is the main question the study is designed to answer.
Phase I: Maximum Tolerated Dose (MTD) of Sorafenib Given With Azacitidine
MTD is defined as highest dose level in which 6 patients treated with at most 1 experiencing a dose limiting toxicity (DLT) during 1st cycle. One cycle of therapy is 7 days of azacitidine (AZA) and 28 days of sorafenib. Starting dose of Sorafenib is 200 mg twice a day azacitidine
Measured: 28 day cycle
Secondary outcomes (1)
Phase II: Number of Participants With Response
Response according to International Working Group response criteria for Acute myeloid leukemia (AML) (JCO 2003; 21: 4642-9): CR defined by presence of <5% blasts in the bone marrow (BM), with >1 X 10^9/L neutrophils and >100 x 10^9/L platelets in the peripheral blood (PB) with no detectable extramedullary disease. Participants who met the above criteria but had neutrophil or platelet counts less than the stated values were considered to have achieved CRi (CR with incomplete recovery of PB counts) or CR with incomplete platelet recovery (CRp) if CR but platelets < 100 x 10^9/L but ≥ 50 x 10^9/L and platelet transfusion independent. Partial response (PR) required all of the hematologic values for a CR but with a decrease of >/= 50% in the percentage of blasts to 5% to 25% in the BM aspirate.
Measured: 90 days

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Azacitidine and Sorafenib in people with Leukemia, 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 15 inclusion and 23 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 6 May 2016. 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?
Yes. Results are posted in the registry (first posted 6 May 2016). 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?
Phase I: Maximum Tolerated Dose (MTD) of Sorafenib Given With Azacitidine (time frame: 28 day cycle). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01254890, which also lists 2 linked publications.
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 6 May 2016.
