Brief Summary

RATIONALE: Monoclonal antibodies, such as alemtuzumab, can 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. PURPOSE: This phase I/II trial is studying the side effects and best dose of alemtuzumab in treating patients with B-cell chronic lymphocytic leukemia.

Outcome Measures

Primary Outcomes (2)

  • Dose-limiting toxicity

    • Dose-limiting toxicity (DLT) and maximal tolerable dose (MTD) DLT is defined as a) all grade III/IV non-hematologic toxicity and b) all grade IV hematologic toxicity lasting for more than 2 weeks (excluding lymphopenia) occuring during or within 4 weeks after end of consolidation therapy.

    28 days after the last dose of study medication

  • Maximum tolerated dose

    • Dose-limiting toxicity (DLT) and maximal tolerable dose (MTD) DLT is defined as a) all grade III/IV non-hematologic toxicity and b) all grade IV hematologic toxicity lasting for more than 2 weeks (excluding lymphopenia) occuring during or within 4 weeks after end of consolidation therapy.

    28 days after the last dose of study medication

Secondary Outcomes (8)

  • Rate of complete minimal residual disease response

    will be tested repeatedly, first time 3 months after the last dose of study medication, last time point 24 months after last dose of study medication

  • Rate of immunophenotypic remission using 4-color flow cytometry

    will be tested repeatedly, first time 3 months after the last dose of study medication,

  • Rate of infections (especially CMV infections and reactivations)

    upt to 24 months after last dose of study medication (end of study)

  • Rate of severe hematologic and non-hematologic side effects

    28 days after the last dose of study medication

  • Pharmacokinetics of alemtuzumab (after IV and subcutaneous administration)

    up to 8 weeks during the alemtuzumab treatment

  • +3 more secondary outcomes

Study Arms (2)

Cohort A: Alemtuzumab i.v.

EXPERIMENTAL

Intravenous administration of alemtuzumab according to the 3 + 3 dose escalation design.

Biological: Alemtuzumab i.v.

Cohort B: Alemtuzumab s.c.

EXPERIMENTAL

After i.v. MTD (maximum tolerable dosage) has been determined, subcutaneous dose escalation is performed according to the same escalation rules as for cohort A, starting with the recommended dose level of i.v. application.

Biological: Alemtuzumab s.c.

Interventions

Alemtuzumab will be administered once per week as a 2 h infusion * Dose level I: 10mg once weekly (start with dose escalation : 3 mg on day 1, 10mg on day 2) Duration * Dose level II: 20mg once weekly (start with dose escalation: 3mg on day 1, 10mg on day 2, 20mg on day 3) * Dose level III: 30mg once weekly (start with dose escalation: 3mg on day 1, 10mg on day 2, 30mg on day 3)

Cohort A: Alemtuzumab i.v.

Alemtuzumab will be administered once per week subcutaneously * Dose level I: 10mg once weekly (start with dose escalation : 3 mg on day 1, 10mg on day 2) Duration * Dose level II: 20mg once weekly (start with dose escalation: 3mg on day 1, 10mg on day 2, 20mg on day 3) * Dose level III: 30mg once weekly (start with dose escalation: 3mg on day 1, 10mg on day 2, 30mg on day 3)

Cohort B: Alemtuzumab s.c.

Eligibility Criteria

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:
