Fludarabine/Rituximab Combined With Escalating Doses of Lenalidomide in Untreated CLL
Fludarabine/Rituximab Combined With Escalating Doses of Lenalidomide in Untreated Chronic Lymphocytic Leukemia (CLL) - a Dose-finding Study With Escalating Starting Dose of Lenalidomide and Concomitant Evaluation of Safety and Efficacy
This is a trial in patients with previously untreated CLL. Eligible patients will receive Lenalidomide with a backbone of Fludarabine and Rituximab for 6 therapy cycles. Lenalidomide will be increased by dose steps of 5 mg every cycle in the absence of limiting toxicity. If limiting toxicity ensues the patients will be treated with last tolerable dose for the remainder of the 6 treatment cycles.
The first 5 patients will start with dose level 5 mg Lenalidomide and further escalating dose. After the fifth patient is included in the study, enrolment will be interrupted until this patient has finished his first treatment cycle. A safety board will evaluate the toxicities of the first 5 patients. If there are more than 2 patients experiencing a dose limiting toxicity (DLT) in the first treatment cycle, the starting dose will not be escalated and further 5 patients will be enrolled with a starting dose of 5 mg Lenalidomide. If only 2 or less patients experience a DLT in the first treatment cycle, the next 5 patients will start the treatment with 10 mg Lenalidomide.
The rational for the higher starting doses stems from the lack of tumor lysis or tumor flare toxicity in this combination on the one hand and from the observation that the very slow escalation from 2,5 mg on led to a lack of efficacy in monotherapy trials due to early progression in a relevant number of cases. The increase of the Lenalidomide dosage should result in an increased efficacy especially at the beginning and a higher cumulative dose of Lenalidomide.
The identification of patients intolerant to Lenalidomide by immunophenotyping of the T cells for validation is also part of this trial, because intolerance seems to be not dose dependent but may be caused by T cell activation. Therefore, early identification of patients intolerant to this form of modern immunochemotherapy and establishing efficient Lenalidomide based combination therapy is an important part of improvement of current CLL treatment.

Beschreibung
Inclusion Criteria:
- Signed written informed consent
- Male or female ≥ 18 years of age
- CLL (as determined by CD23+, CD5+, CD19+)
- Treatment indication as defined by the NCI Workshop criteria (see appendix 6 and reference 10)
- ECOG ≤ 2
- No previous treatment of the CLL by chemotherapy, radiotherapy (except localized radiotherapy of 1 lymphatic area) or immunotherapy
- Life expectancy > 6 months (except prognosis due to high risk CLL)
Exclusion Criteria:
- Active bacterial, viral or fungal infection
- Positivity for HIV, Hepatitis B or C
- Patients with known history of thromboembolic events
- Reduced organ functions and bone marrow dysfunction not due to CLL
- Creatinine clearance of below 30 ml/min

- Patients with a history of other malignancies within 2 years prior to study entry (except for adequately treated carcinoma in situ of the cervix; basal or squamous cell skin cancer; low grade, early stage localized prostate cancer treated surgically with curative intent; good prognosis DCIS of the breast treated with lumpectomy alone with curative intent)
- Patients with medical co-morbid conditions that would require long term use (> 1 month) of systemic corticosteroids during study treatment
- Patients with a history of severe cardiac disease; e.g. NYHA Functional Class III or IV heart failure, myocardial infarction within 6 months, ventricular tachyarrhythmias requiring ongoing treatment, or unstable angina
- Other known co-morbidity with the potential to dominate survival

- Concurrent chronic systemic immune therapy, chemotherapy, or hormone therapy not indicated in the study protocol
- Administration of any investigational agent(s) within 4 weeks prior to entry
- Pregnancy or lactation
- Medical or psychological condition which in the opinion of the Investigator would not permit the patient to complete the study or sign meaningful informed consent
