简要总结
This phase I trial is studying the side effects and best dose of alemtuzumab when given together with bendamustine hydrochloride in treating patients with relapsed chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) that did not respond to fludarabine phosphate. Drugs used in chemotherapy, such as bendamustine hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as alemtuzumab, can also block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Giving bendamustine hydrochloride together with alemtuzumab may kill more cancer cells.
详细描述
PRIMARY OBJECTIVES:
I. Evaluate the safety of the combination of alemtuzumab and bendamustine (bendamustine hydrochloride) in patients with advanced CLL.
II. Establish the maximum tolerated dose of alemtuzumab up to the standard dose of 30mg thrice weekly when combined with bendamustine at a standard dose of 70 mg/m^2 day 8 and 9 monthly.
III. Define a recommended dose for subsequent Phase II studies. IV. Evaluate preliminary evidence of activity as determined by response rates with correlation to EAS flow cytometry.
OUTLINE: This is a dose-escalation study of alemtuzumab.

- •Males and females 18 years of age or older.
- •Patients must be relapsed or refractory and have been treated with a minimum of one prior purine analog-based chemotherapy regimen (e.g., fludarabine, cladribine, or pentostatin).
- •All previous cancer therapies, radiation, hormonal therapy and surgery, must have been discontinued at least 28 days prior to the start of treatment. Any cytotoxic chemotherapy must have been discontinued 28 days prior to the start of treatment. Acute toxicities from prior therapy must have resolved to Grade ≤ 1 above baseline.

- •Serum creatinine 2 X ULN or less. In addition, the calculated glomerular filtration rate (GFR) must be > 30cc/min.
- •ECOG Performance Status 2 or less.
- •Anticipated survival of at least 3 months.
- •For men and women of child-producing potential, use of effective contraceptive methods during the study and for one month after discontinuation of treatment.
排除标准
- •Pregnant or lactating women.
- •Severe chronic obstructive pulmonary disease with hypoxemia or an uncorrectable pulmonary compromise.
- •Seizures not controlled by anticonvulsant therapy.
- •Participation in any investigational drug study within 28 days before study entry.
- •Patients with second malignancy requiring active treatment.
- •Active, symptomatic bacterial, fungal, or viral infection including active HIV or viral (A, B, or C) hepatitis.
- •Clinically significant bleeding event within the last 3 months, unrelated to trauma, or underlying condition that would be expected to result in a bleeding diathesis.
- •Patients with life- or function-threatening CLL complications (e.g., cord compression, hemolytic crisis, urinary tract obstruction).
- •Any illness or condition that in the opinion of the investigator may affect safety of treatment or evaluation of any of the study's endpoints.
- •Systemic treatment for CLL/SLL within 28 days of study entry
- •Subjects with a history of leukemic meningitis, or signs and symptoms suggestive of leukemic meningitis, must have a negative lumbar puncture within 2 weeks of study entry.
