A MULTICENTER, PHASE III, OPEN-LABEL, RANDOMIZED STUDY IN RELAPSED/REFRACTORY PATIENTS WITH CHRONIC LYMPHOCYTIC LEUKEMIA TO EVALUATE THE BENEFIT OF GDC-0199 (ABT-199) PLUS RITUXIMAB COMPARED WITH BENDAMUSTINE PLUS RITUXIMAB

Recruitment & Eligibility

Status: Authorised-recruitment may be ongoing or finished

Sex: All

Target Recruitment: 389

Inclusion Criteria

Diagnosis of CLL that meets published diagnostic criteria (Hallek et al. 2008).
Patients must have peripheral blood B-lymphocyte counts which clonally express CD5, CD19/20 and CD23 and are either kappa or lambda light-chain restricted.
Pro-lymphocytes may comprise no more than 55% of total circulating lymphocytes.
At initial diagnosis of CLL (ie, prior to front-line treatment), the peripheral lymphocyte count must have been >5000/mm3. Patients must meet the following criteria for relapsed or refractory CLL (per the iwCLL guidelines [Hallek et al. 2008]):
-Relapsed disease: a patient who previously achieved a CR or PR, but after a period of 6 months or more demonstrates evidence of progression;
-refractory disease: treatment failure or disease progression within 6 months of the last anti-leukemia therapy.
• Female patients who are not surgically sterile or postmenopausal (for at least 1 year) must practice at least one of the following methods of birth control throughout the duration of study participation and for at least 30 days 3 months after study treatment or 12 months after completing therapy with rituximab, whichever is later:
Total abstinence from sexual intercourse
A vasectomized partner
Hormonal contraceptives (oral, parenteral, vaginal ring, or transdermal) that started at least 3 months prior to study drug administration
Double-barrier method (condom ? diaphragm or cervical cup with spermicidal contraceptive sponge, jellies, or cream)
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 185
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range 185

Exclusion Criteria

Transformation of CLL to aggressive NHL (eg, Richter's transformation, prolymphocytic leukemia, or DLBCL) or CNS involvement by CLL.
Positive test results for chronic hepatitis B infection (defined as positive HBsAg serology)
Patients with occult or prior hepatitis B infection (defined as positive total HBcAb and negative HBsAg) may be included if HBV DNA is undetectable. These patients must be willing to undergo monthly polymerase chain reaction (PCR) HBV DNA testing.
Positive test results for hepatitis C (HCV antibody serology testing)
Patients positive for HCV antibody are eligible only if PCR is negative for HCV RNA.
