- Brief Summary
Assessment of safety and efficacy of with fludarabine and cyclophosphamide (FC) combined with ofatumumab (FCO2) in previously untreated "young" patients with Chronic Lymphocytic Leukemia (CLL).
- Detailed Description
Given that:
* rituximab, fludarabine and cyclophosphamide (FCR) front-line treatment was associated with a high OR rate, superior PFS and OS as compared to fludarabine and cyclophosphamide regimen;
* a direct relationship between the dose of rituximab and the response rate has been reported;
* ofatumumab, as single agent, proved activity in CLL patients with refractory disease;
* ofatumumab, fludarabine and cylophosphamide (O-FC) front-line treatment has been associated with a high complete response (CR) rate;
* the expected grade 3-4 granulocytopenia could led to reduce the dose intensity of study drugs (FC) and increase the infection rate; a schedule combining FC with an increased dose of ofatumumab associated to primary phrophylaxis of granulocytopenia could be associated with an improvement in the CR rate. The purpose of this study is to determine whether we could improve the CR rate of the golden standard treatment for fit patients with CLL , the FCR regimen, with a chemoimmunotherapy including FC combined with an increased dose of the monoclonal antibody ofatumumab, given every other week (FCO2) associated with a primary prophylaxis of granulocytopenia.

- Primary Outcome Measures
Name Time Method Number of complete responses. After 8 months from study entry. The complete response (CR) rate after FCO2 front-line treatment.
- Secondary Outcome Measures
Name Time Method Number of patients needing a new CLL Treatment. After 32 months from study entry. Time to a new CLL treatment (TTT) will be calculated from the date of last treatment dose until date of a new treatment received for CLL, where death occurred before the new treatment will be considered as competing risk. Patients still alive without receiving a new treatment will be censored at the time of the last follow-up.
Number of patients in overall survival After 32 months from study entry. Overall survival (OS): defined as the time interval between the date of first treatment dose - induction phase- and the date of death for any cause; patients still alive will be censored at the moment of last follow-up.
Outcome of patients according to clinical and biologica variables. After 32 months from study entry. Outcome of patients (response, PFS OS) according to clinical and biologic variables (age; size of nodes, 2-microglobulin, lymphocyte count, stage, IgVH, p53, FISH, ZAP-70, CD38, FLCs).
Number of overall responses. After 8 months from study entry. Overall Response (OR) rate after FCO2 front-line treatment.
Number of toxic events. After 32 months from study entry. Toxicity of treatment according the last NCI criteria.
Number of patients in progression-free survival. After 32 months from study entry. Progression-free survival (PFS) calculated from the date of first treatment dose - induction phase - until the date of the first documentation of progressive disease or until death (whatever the cause), whichever occurs first. Patients still alive and known to be progression free will be censored at the moment of last follow-up.
