E.2.3 | Trial contains a sub-study | Information not present in EudraCT |
E.3 | Principal inclusion criteria |
The trial population will be comprised of patients with a diagnosis of B-CLL who have failed both fludarabine and alemtuzumab and who have received an alkylating therapy such as cyclophosphamide or chlorambucil and who have active disease. Active B-CLL is defined and confirmed according to the NCIWG guidelines 1 and with an indication for treatment. Failing at least one fludarabine-containing treatment regimen is defined as 1. Refractory to one fludarabine -containing treatment regimen, defined as a. failure to achieve PR or CR to at least one fludarabine-containing treatment regimen; or, b. disease progression while on a fludarabine-containing treatment regimen; or, c. disease progression in responders within 6 months of the last dose of a fludarabine-containing treatment regimen 2. Intolerant to fludarabine, defined as a. Discontinuation of therapy due to side effects/toxicity whether or not response occurred; or b. Ineligible to treatment with fludarabine due to history of previous fludarabine-induced autoimmune hemolytic anemia or autoimmune thrombocytopenia Failing at least one alemtuzumab-containing treatment regimen is defined as 1. Refractory to one alemtuzumab-containing treatment regimen, defined as a. failure to achieve PR or CR to at least one alemtuzumab-containing treatment regimen; or, b. disease progression while on a alemtuzumab-containing treatment regimen; or, c. disease progression in responders within 6 months of the last dose of a alemtuzumab-containing treatment regimen 2. Intolerant to alemtuzumab, defined as a. Discontinuation of therapy due to side effects/toxicity whether or not response occurred; or, b. Ineligible to treatment with alemtuzumab due to concurrent medical conditions, such as i. previous pneumocystis carinii pneumonia PCP ii. history of other severe opportunistic infections iii. repeated grade 3 or 4 infections of other types A patient must have failed at least one fludarabine-containing treatment regimen and one alemtuzumab-containing treatment regimen, as defined above. Patients must have received at least one alkylating therapy. Patients may have received at most five previous treatment regimens for B-CLL. Patients must have an ECOG Performance Status of 0 or 1 and a life expectancy of at least 4 months. The patients should be 8805; 18 years of age and have given informed consent.

E.4 | Principal exclusion criteria |
The most important exclusion criteria consist of more than two previous treatment regimens that included purine analogues e.g. fludarabine, cladribine, pentostatin , more than five previous treatment regimens for B-CLL, previous treatment with alemtuzumab within 6 weeks prior to Visit 1, autologous and allogeneic stem cell transplantation at any time, radioimmunotherapy at any time or anticancer therapy within 4 weeks prior to Visit 1 and known or suspected transformation of B-CLL. |
