Trial Information

Ofatumumab Early Treatment for High-Risk Treatment-Naive, Early Stage (0-II) Patients With Chronic Lymphocytic Leukemia (CLL)


The Study Drug:

Ofatumumab is designed to bind to the surface of some of the white blood cells (B-cells).
It may destroy cancer cells that come from B-cells.

Study Drug Administration:

If you are found to be eligible to take part in this study, you will receive a "loading
dose" (a lower dose given first, to lower the risk of a bad reaction to the study drug) of
ofatumumab by vein on Day 1 of Cycle 1. The loading dose is less than one-third (1/3) of
the normal dose. You will then receive the normal dose over 4 hours 1 time each week (+/- 3
days). The doses may be given more slowly, if your doctor thinks it is needed. All doses of
the study drug will be given at M. D. Anderson.

Benadryl (diphenhydramine) and glucocorticoids (steroids such as prednisolone) will be given
by vein 30 minutes to 2 hours before you receive ofatumumab to help prevent side effects.
You will also take pills of acetaminophen (Tylenol) to help prevent side effects. If no
side effects occur, these "pre-medications" may be reduced or not given after the second
infusion.

Study Visits:

One (1) time each week, before you receive ofatumumab:

- You will have a physical exam, including measurement of your vital signs.

- You will be asked about how you are feeling, about any side effects you may be having,
and about any changes in your health since the last visit.

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

Length of Study:

You may continue taking the study drug until Day 50, 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, if you develop hepatitis B, or if you decide to go
off study.

End-of-Treatment Visit:

On the day of your last treatment or after you stop receiving 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 how you are feeling, about any side effects you may be having,
and about any changes in your health since the last visit.

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

- If the doctor thinks it is needed, blood (about 2 teaspoons) will be drawn for
hepatitis testing.

Follow-Up:

About 3 months (+/- 2 weeks) after the end-of-treatment visit, 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 how you are feeling, about any side effects you may be having,
and about any changes in your health since the last visit.

- You will have a bone marrow aspirate and biopsy, as well as CT scans of the chest,
abdomen, and pelvis, to check the status of the disease.

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

- If the doctor thinks it is needed, blood (about 2 teaspoons) will be drawn for
hepatitis testing.

Every 3 months (+/- 4 weeks) after the end-of-treatment visit for 6 months:

- You will have a physical exam, including measurement of your vital signs.

- You will be asked about how you are feeling, about any side effects you may be having,
and about any changes in your health since the last visit.

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

- If the doctor thinks it is needed, blood (about 2 teaspoons) will be drawn for
hepatitis testing.

Every year (+/- 4 weeks) after the end-of-treatment visit:

- You will have a physical exam, including measurement of your vital signs.

- You will be asked about how you are feeling, about any side effects you may be having,
and about any changes in your health since the last visit.

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

- You will have a bone marrow aspirate and biopsy, as well as CT scans of the chest,
abdomen, and pelvis, to check the status of the disease.

This is an investigational study. Ofatumumab is FDA approved and commercially available for
use in the treatment of CLL. The use of ofatumumab as an early treatment for patients with
CLL/SLL who have not received other treatment is investigational.

Up to 44 patients will take part in this study. All will be enrolled at M. D. Anderson.


Inclusion Criteria:



1. Diagnosis of chronic lymphocytic leukemia (CLL)/ small lymphocytic leukemia (SLL),
previously untreated, Rai stage 0-ll

2. At least 1 of the following high-risk features for previously untreated patients: Rai
stage II disease; Rai stage 0-I with disease-related fatigue; Serum beta2M >/= 3
mg/L; Absolute lymphocyte count >/= 25,000/uL; Unmutated IGHV gene or IGHV3-21; ZAP70
positive (>/= 20% by flow cytometry or positive by immunohistochemistry); CD38
positive (>/= 30% by flow cytometry); OR Deletion 11q or 17p by FISH

3. ECOG PS
4. Age >/= 18 years

5. Patients must have adequate renal and hepatic function (creatinine <2mg/dL, total
bilirubin <2mg/dL). Patients with renal or liver dysfunction due to organ
infiltration with CLL may be eligible after discussion with the study chairman

6. Provide informed consent

7. Female patients (including those < 1 year post-menopausal) and male patients who have
not undergone previous surgical sterilization must agree to use contraception.

Exclusion Criteria:

1. Presence of 2008 IWCLL/NCI-WG indication for CLL treatment: Constitutional symptoms
related to CLL/SLL: Fever > 100.5 degrees F for >/= 2 weeks or night sweats for > 1
mo, both without evidence of infection; Unintentional weight loss of >/= 10% body
weight in previous 6 months; Extreme fatigue (ECOG PS > 2; inability to work or
perform usual activities); Lymphocyte doubling time of in absolute lymphocyte count within 2 months; Progressive anemia (Rai stage III) or
thrombocytopenia (Rai stage IV); Recurrent infections unrelated to
hypogammaglobulinemia; Autoimmune phenomenon poorly responsive to corticosteroids or
other standard therapy; Massive, progressive or symptomatic lymphadenopathy (> 10 cm
in longest diameter) or splenomegaly (> 6 cm below left costal margin)

2. Prior or concurrent chemotherapy, radiotherapy, or immunotherapy for CLL

3. Active infection (febrile and requiring IV/PO antibiotics), including hepatitis C or
HIV, or significant medical illness including renal, cardiac, pulmonary disease, or
current active hepatic or biliary disease (with exception of patients with Gilbert's
syndrome, asymptomatic gallstones, liver metastases or stable chronic liver disease
per investigator assessment)

4. Positive serology for Hepatitis B virus (HB) defined as a positive test for HBsAg. In
addition, if negative for HBsAg but HBcAb positive (regardless of HBsAb status), a HB
DNA test will be performed and if positive, the patient will be excluded.

5. Pregnant or breast feeding females are not eligible.
