Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The Study Drug:

OPB-31121 is designed to block certain proteins in cancer cells that cause the cancer cells to reproduce and form more cancer cells.

Study Groups:

If you are found to be eligible to take part in this study, you will be assigned to a dose level of OPB-31121 based on when you joined this study. The first group of participants will receive the lowest dose level. Each new group will receive a higher dose than the group before it, if no intolerable side effects were seen. This will continue until the highest tolerable dose of OPB-31121 is found.

Study Drug Administration:

On Days 1-21 of each 28-day cycle, you will take the study drug by mouth 2 times a day. You should take the study drug with at least 1 full glass of room temperature, still (non-carbonated) water, within 30 minutes after eating a snack or meal. You should either remain sitting upright or standing for at least 30 minutes after you take the study drug. You will be given directions by the study doctor, the study nurse, and/or the study pharmacist on how to take the study drug at home.

Study Visits:

On Day 1 of Cycle 1, the following tests and procedures will be performed:

* You will have a physical exam, including measurement of your vital signs.
* You will have 5 ECGs: 1 before the morning dose of study drug and at 1, 2, 4, and 8 hours after the morning dose.
* Blood (about 3 tablespoons) will be drawn for routine tests.
* Your performance status will be recorded.
* You will be asked about any drugs you may be taking and if you have experienced any side effects.
* Blood (about 2 teaspoons each time) will be drawn before the morning dose and then 6 more times over the next 12 hours after the dose for pharmacokinetic (PK) testing. PK testing measures the amount of study drug in the body at different time points.
* Blood (about 2 teaspoons) for pharmacodynamic (PD) testing will be drawn before the morning dose. PD testing is used to look at how the level of study drug in your body may affect the disease.
* Blood (about 1 teaspoon) will be drawn for pharmacogenomic (PGx) testing. PGx testing looks at how differences in people's genes may affect if and how well the study drug may affect the disease.
* Women who are able to become pregnant will have a urine pregnancy test.

On Day 2 of Cycle 1, before your morning dose of study drug, the following tests and procedures will be performed:

* Blood (about 1 teaspoon) will be drawn for a troponin test.
* Blood (about 4 teaspoons) will be drawn for PK and PD testing.
* Your performance status will be recorded.
* You will be asked about any drugs you may be taking and if you have experienced any side effects.

On Days 8, 15, 21, and 28 of Cycle 1, the following tests and procedures will be performed:

* You will have a physical exam, including measurement of your vital signs.
* You will have an ECG.
* Blood (about 3 tablespoons on Days 8 and 15; about 1 tablespoon on Days 21 and 28) and urine will be collected for routine tests.
* Your performance status will be recorded.
* You will be asked about any drugs you may be taking and if you have experienced any side effects.

On Day 21 of Cycle 1, blood (about 2 teaspoons each time) will be drawn for PK testing before the morning dose and then 6 more times over the next 12 hours after the dose. Blood (about 2 teaspoons each time) will also be drawn for PD testing.

On Day 22 of Cycle 1, before your morning dose of study drug, the following tests and procedures will be performed:

* Your performance status will be recorded.
* You will be asked about any drugs you may be taking and if you had any side effects from them.
* Blood (about 2 teaspoons) will be drawn for PK testing before your morning dose of the study drug.

On Days 1, 15, and 28 of Cycles 2 and beyond, the following tests and procedures will be performed:

* You will have a physical exam, including measurement of your weight and vital signs.
* Your performance status will be recorded.
* You will be asked about any drugs you may be taking and if you had any side effects from them.
* You will have an ECG.
* You will have an echocardiogram or MUGA scan.
* Blood (about 3 tablespoons) will be drawn for routine tests.
* You will be asked about any drugs you may be taking and if you have experienced any side effects.
* Women who are able to become pregnant will have a urine pregnancy test.

About every 8 weeks, you will have an x-ray, CT scan, or MRI scan to check the status of the disease.

Length of Study:

You may continue taking the study drug for as long as you are benefitting. You will be taken off study if the disease gets worse, you experience intolerable side effects, or your doctor thinks that it is no longer in your best interest to receive the study drug.

You may choose to stop taking the study drug at any time. You should tell the study doctor right away if you are thinking about stopping your participation in this study. The study doctor will talk to you about how to safely stop taking the study drug.

End-of-Study Visi:t

Within 14 days after the last dose of study drug, you will return for a final visit. The following tests and procedures will be performed at the final visit:

* You will have a physical exam, including measurement of your vital signs.
* You will have an ECG.
* Blood (about 4 tablespoons) and urine will be collected for routine tests.
* You will have either an ECHO or MUGA scan.
* You will have an x-ray, CT scan, or MRI scan to check the status of the disease.
* Your performance status will be recorded.
* You will be asked about any drugs you may be taking and if you have experienced any side effects.

Follow-Up:

You will be called about 30 days after the last dose of OPB-31121 and asked if you have experienced any new or ongoing side effects.

This is an investigational study. OPB-31121 is not FDA approved or commercially available. At this time, OPB-31121 is only being used in research.

Up to 36 patients will take part in this multicenter study. Up to 18 will be enrolled at M. D. Anderson.
