Research Study Description
Eligibility Criteria (must meet the following to participate in this study)
- Genders Eligible for Study: Both
- Men and women = 18 years of age.
- Eastern Cooperative Oncology Group (ECOG) performance status of = 2.
- Pathologically confirmed de novo DLBCL; subjects must have available archival tissue for central review to be eligible.
- Relapsed or refractory disease, defined as either: 1) recurrence of disease after a complete remission (CR), or 2) partial response (PR), stable disease (SD), or progressive disease (PD) at completion of the treatment regimen preceding entry to the study (residual disease):Subjects must have previously received an appropriate first-line treatment regimen.Subjects with suspected residual disease after the treatment regimen directly preceding study enrollment must have biopsy demonstration of residual DLBCL. Subjects who have not received high dose chemotherapy/autologous stem cell transplant (HDT/ASCT) must be ineligible for HDT/ASCT as defined by meeting any of the following criteria: Age = 70 years ,Diffuse lung capacity for carbon monoxide (DLCO) < 50% by pulmonary function test (PFT), Left ventricular ejection fraction (LVEF) < 50% by multiple gated acquisition(MUGA)/echocardiograph (ECHO), Other organ dysfunction or comorbidities precluding the use of HDT/ASCT on the basis of unacceptable risk of treatment-related morbidity, Subject refusal of HDT/ASCT.
- Subjects must have = 1 measurable (> 2 cm in longest dimension) disease sites on computed tomography (CT) scan.
Other eligibility criteria may apply.
