SB939

Alfonso Quintas-Cardama, MD

The goal of this clinical research study is to learn if SB939 can help to control myelofibrosis. The safety of this drug will also be studied.

The Study Drug:

SB939 is designed to change the DNA (genetic material) of cancer cells. This may keep the cells from growing and cause them to die.

This is the first study in which SB939 is given to patients with myelofibrosis.

Study Drug Administration:

If you are found to be eligible to take part in this study, you will take SB939 by mouth 3 times a week for the first 3 weeks of every 4-week cycle. In some cases, the study doctor may decide your dose can be raised sometime after Cycle 1.

SB939 can be taken at any time of day, 2 hours before or 2 hours after a meal. You should take SB939 at about the same time each day. Do not open, break, or chew the capsules.

If you have any side effects, the doctor may change the amount or how often you take SB939.

You will fill out a study drug diary to keep track of your SB939 doses. You should bring the diary and all used and unused bottles of study drug with you to every study visit.

Study Visits:

At every study visit, you will be asked about any side effects you have had and any drugs you may be taking.

On Day 1 of Cycle 1 (+/- 3 days):

* You will have a physical exam, including measurement of your vital signs.
* You will be asked about any blood transfusions you have had and drugs you have taken since the last visit.
* Your performance status will be recorded.
* Blood (about 4 teaspoons) will be drawn for routine tests.
* You will have an ECG before taking this medication, about 10 minutes after taking medication, and 4-6 hours after taking medication.

On Day 8 of Cycle 1 (+1-3 days), blood (about 2 teaspoons) will be drawn for routine tests.

On Day 15 of Cycle 1 (+/- 3 days):

* You will have a physical exam, including measurement of your vital signs.
* Blood (about 4 teaspoons) will be drawn for routine tests.
* You will have an ECG before taking this medication, about 10 minutes after taking medication, and 4-6 hours after taking medication.

On Day 22 of Cycle 1 (+1-3 days), blood (about 2 teaspoons) will be drawn for routine tests.

On Day 1 of Cycles 2 and 3 (+/- 3 days):

* You will have a physical exam, including measurement of your vital signs.
* You will be asked about any blood transfusions you have had since the last visit.
* Your performance status will be recorded.
* Blood (about 4 teaspoons) will be drawn for routine tests.
* You will have an ECG.

On Day 1 of Cycles 4 and beyond (+/- 3 days), or every 3 cycles starting on Day 1 of Cycle 6 (+/- 3 days) if the doctor decides your schedule can change (if you have not had serious side effects):

* You will have a physical exam, including measurement of your vital signs.
* You will be asked about any blood transfusions you have had and drugs you have taken since the last visit.
* Your performance status will be recorded.
* Blood (about 4 teaspoons) will be drawn for routine tests.
* You will have a bone marrow biopsy and aspiration to check the status of the disease, if the doctor thinks it is needed.
* You will have an ECG at every visit to MD Anderson.

If your study visit schedule is changed to every 3 cycles (Day 1 of Cycles 6, 9, and so on), blood (about 4 teaspoons) will be drawn for routine tests every 28 days (+/- 3 days). These tests will be done at your local doctor's office. Every 28 days (+/- 3 days), the study staff will also call you to ask how you are doing and if you have had any side effects.

You may have additional bone marrow biopsies and aspirations and ECGs any time the doctor thinks it is needed. The study visits may also occur more often than described above, if the doctor thinks it is needed.

Length of Study:

You may continue taking the study drug for as long as the doctor thinks it is in your best interest. You will no longer be able to take the study drug if the disease gets worse, if intolerable side effects occur, or if you need radiation therapy, surgery, or other chemotherapy.

Your participation on the study will be over once you have completed the end-of-treatment visit and follow-up.

End-of-Treatment Visit:

After you stop taking the study drug for any reason, the following tests and procedures will be performed:

* You will have a physical exam, including measurement of your vital signs.
* You will be asked about any blood transfusions you have had and drugs you have taken since the last visit.
* Your performance status will be recorded.
* Blood (about 4 teaspoons) will be drawn for routine tests.
* You will have a bone marrow biopsy and aspiration to check the status of the disease, if the doctor thinks it is needed.

Follow-up:

The study staff will call you 30 days and 60 days after your last dose of the study drug (+/- 3 days). You will be asked how you are doing and if you have had any side effects.

If you have any side effects within 60 days after you stop taking the study drug, you may have extra tests and procedures. For example, blood (about 2 teaspoons) may be drawn for routine tests. If you are still having side effects, the study staff will continue calling you to ask how you are doing until the side effects get better. The schedule for how often you are called will depend on the side effects.

This is an investigational study. SB939 is not FDA approved or commercially available. It is currently being used for research purposes only.

Up to 41 patients will take part in this study. All will be enrolled at the University of Texas (UT) MD Anderson Cancer Center.

Study of SB939 in Subjects With Myelofibrosis

A Phase 2, Prospective, Open-Label Study to Determine the Safety and Efficacy of SB939, A Histone Deacetylase Inhibitor, in Subjects With Primary, Post-Polycythemia Vera, or Post-Essential Thrombocythemia Myelofibrosis (PMF; Post-Polycythemia Vera (PV) Myelofibrosis (MF), Or Post- Essential Thrombosis (ET) MF

Objective response defined as Complete, Partial response, and Clinical Improvement based on International Working Group (IWG) Criteria: Complete remission (CR): Absence transfusion \& growth factor support AND Complete resolution disease-related symptoms/signs; Peripheral blood count remission; Normal leukocyte differential; Bone marrow histological remission. Partial remission (PR): All CR except bone marrow histological remission. Clinical improvement (CI): No CR/PR, disease progression with one: ≥2 g/dL increase hemoglobin level or transfusion independent; Either ≥50% reduction in palpable splenomegaly of spleen ≥10 cm baseline or spleen palpable at \>5 cm baseline becomes not palpable; ≥100% increase in platelet count \& absolute platelet count ≥50,000 x 10\^9/L; or ≥100% increase in absolute neutrophil count (ANC) \& ANC ≥0.5 x 10\^9/L. Progressive disease: Progressive splenomegaly or Leukemic transformation confirmed by bone marrow blast of ≥20%; or Increase peripheral blood blast

The purpose of this study is to find out what effects a new drug SB939 has on you and your sarcoma.

This research is being done because there is a need for better treatment options for advanced or recurring sarcoma.

SB939 has been shown to shrink tumours in animals and some people and seems promising but it is not clear if it has any positive effects in sarcoma.

Objectives:

1. - To determine the efficacy of SB939 in translocation associated sarcoma patients.
2. - To determine response duration, stable disease rate and progression free survival.
3. - To evaluate toxicity of SB939.
4. - To investigate potential molecular factors predictive of response.

60mg SB939 will be given every other day 3 times a week for 3 weeks followed by a week off. Patients may receive a maximum of 12 cycles if they have a response to treatment in the absence of disease progression or unacceptable toxicity. Patients with stable disease may continue therapy for a maximum of 6 cycles.

A Study of SB939 in Patients With Translocation-Associated Recurrent/Metastatic Sarcomas

A Phase II Study of SB939 in Patients With Translocation-Associated Recurrent/Metastatic Sarcomas

The primary endpoint of this study is objective tumour response using RECIST 1.1 \[Eisenhauer 2009\]. Response is defined as 30% decrease in the sum of the diameters of the target lesions (partial response) maintained for at least 4 weeks, or complete disappearance of disease and cancer related symptoms (complete response), also maintained for at least 4 weeks. The median and range of the duration of response will be assessed. A 95% confidence interval for the true objective response rate will be given.
