Last Updated: 2016-12-06

Basic Information

• Recruitment Status: WITHDRAWN
• Clinical Phase: PHASE2
• Study Classification: INTERVENTIONAL
• Study Start Date: 2015-07-31

Brief Summary

The goal of this clinical research study is to learn if urelumab given in combination with rituximab can help to control CLL or SLL. The safety of the drug combination will also be studied.

Detailed Description

Study Drug Administration:

If you are found to be eligible to take part in this study, you will receive rituximab by vein over 4-6 hours on Days 1, 8, 15, 22, 43, and 64 of each 84 day (12 week) cycle.

You will receive urelumab by vein over about 1 hour on Days 2, 23, 44, and 65 of each cycle.

There will be a 2-week period between each study cycle.

Study Visits:

On Days 1, 8, 15, 22, 43, and 64 of each cycle:

• Blood (about 2 tablespoons) will be drawn for routine tests.
• You will have a physical exam.

On Days 2, 29, 36, 50, 57, 71, and 78 of each cycle, blood (about 2 tablespoons) will be drawn for routine tests.

At the end of each cycle (about Day 85):

• Blood (about 2 tablespoons) will be drawn for routine tests.
• You will have a physical exam.
• You will have a bone marrow aspiration and biopsy to check the status of the disease.
• You will have a CT or PET scan to check the status of the disease.

You will have blood draws, CT scans (or PET scans) and/or bone marrow aspiration and biopsies at any time that the doctor thinks it is needed while you are on study.

Length of Study:

You may receive up to 2 cycles of study drugs. However, your study doctor may allow you to receive the study drugs beyond Cycle 2. You will no longer be able to take the study drugs if the disease gets worse, if intolerable side effects occur, or if you are unable to follow study directions.

Your participation on the study will be over after the follow-up visits.

End-of-Study Visit:

If you are taken off study for any reason, the following tests and procedures will be performed:

• You will have a physical exam.
• Blood (about 2-3 tablespoons) will be drawn for routine tests.
• If the doctor thinks it is needed, you will have a bone marrow aspirate and CT or PET scan to check the status of the disease.

Long-Term Follow-Up:

After you are no longer on study, 1 time every month:

• You will have a physical exam.
• Blood (about 2-3 tablespoons) will be drawn for routine tests.

Every 3 months, if the doctor thinks it is needed, you will have a bone marrow aspirate and CT or PET scan to check the status of the disease.

Other Testing:

The study staff may ask you to take part in other MD Anderson clinical research study (PA13-0291) for additional research testing. The study doctor will discuss this with you and, if you decide to take part, you will sign a separate consent document.

This is an investigational study. Urelumab is not FDA approved or commercially available. Rituximab is FDA approved and commercially available for the treatment of patients with CLL. The use of these drugs in combination is investigational. The study doctor can explain how the drugs are designed to work.

Up to 24 participants will be enrolled in this study. All will take part at MD Anderson.

Eligibility Criteria

Inclusion Criteria

1. Patients will have a diagnosis of CLL or SLL who meet one or more criteria for active disease as defined by the International Working Group for CLL (IWCLL) and are relapsed and/or refractory after at least one prior therapy.

2. Age 18 years or older.

3. Eastern Cooperative Oncology Group (ECOG) Performance Status </= 2.

4. Patients must have adequate renal and hepatic function: -- Serum bilirubin </= 1.5 x upper limit of normal (ULN). For patients with Gilbert's disease, serum bilirubin up to </= 3 x ULN is allowed provided normal direct bilirubin, -- Serum creatinine </= 1.5 x ULN, -- ALT and AST </= 3 x ULN.

5. Females of childbearing potential must have a negative serum or urine beta human chorionic gonadotrophin (Beta-hCG) pregnancy test result within 24 hours prior to the first dose of treatment and must agree to use an effective contraception method during the study and for 12 months following the last dose of the study drugs. Females of non- childbearing potential are those who are postmenopausal greater than 1 year or who have had a bilateral tubal ligation or hysterectomy. Males who have partners of childbearing potential must agree to use an effective contraceptive method during the study and for 31 weeks following the last dose of study drugs. Acceptable methods of contraception are condoms with contraceptive foam; oral, implantable or injectable contraceptives; contraceptive patch; intrauterine device; diaphragm with spermicidal gel; or a sexual partner who is surgically sterilized or post-menopausal.
