En studie av Obinutuzumab [RO5072759 (GA101)] i kombination med CHOP-kemoterapi hos patienter med tidigare obehandlade avancerade diffusa stora B-cellslymfom (GATHER)
En fas II, öppen, multicenterstudie av effektivitet, säkerhet och biomarkörer hos patienter med tidigare obehandlade avancerade diffusa stora B-cellslymfom behandlade med GA101 (RO5072759) i kombination med CHOP kemoterapi
This open-label, multicenter study will evaluate the efficacy and safety of obinutuzumab [RO5072759 (GA101)] in combination with CHOP (Cyclophosphamide, Doxorubicin, Vincristine, Prednisone) chemotherapy in patients with advanced diffuse large B-cell lymphoma. Patients will receive 8 cycles of obinutuzumab (1000 mg intravenously on Day 1 of each 21-day cycle, during Cycle 1 obinutuzumab will also be infused on Days 8 and 15) in combination with CHOP chemotherapy on Day 1 of cycles 1 to 6. A substudy will investigate the drug-drug interaction of obinutuzumab with CHOP chemotherapy agents. For the substudy, an additional cohort of approximately 15 patients are planned to be enrolled at a subset of investigational sites.

Complete Response (CR) Rate as Assessed by the Investigator at the End of Treatment
Tidsram: From the first dose of study treatment to end of treatment response assessment (approximately 228 to 258 days)
|
Complete response rate is defined as the percentage of participants with Complete Response (CR) according to the Revised Response Criteria for Malignant Lymphoma (Cheson et al., 2007). Disease response was evaluated by the investigator using regular clinical and laboratory examinations, fluorodeoxyglucose-positron emission tomography (FDG-PET) and computed tomography (CT). CR is the disappearance of all evidence of disease. |

Overall Response Rate (ORR) as Assessed by the Investigator at the End of Treatment
Tidsram: From the first dose of study treatment to end of treatment response assessment (approximately 228 to 258 days)
|
Overall response rate was defined as the percentage of participants with Complete Response (CR) or Partial Response (PR) according to the Revised Response Criteria for Malignant Lymphoma (Cheson et al., 2007). Disease response was evaluated by the investigator using regular clinical and laboratory examinations, FDG-PET and computed tomography (CT). CR is the disappearance of all evidence of disease. PR is at least 50% regression of measurable disease compared to tumors measured by a baseline scan and no new sites. |

Pharmacodynamics: Number of Participants With Peripheral Blood B-cell Recovery
Tidsram: Up to approximately 30 months

B-cell recovery was defined as a CD19 result >= 0.07 × 10^9/L, where CD19 was previously depleted. B-cell recovery was only considered possible following the last dose of study treatment. The number of participants with B-cell recovery from End of Treatment to 6 months of Follow-up is reported in two categories: Recovery with Progressive Disease (PD) [PD before B-cell recovery or PD within 45 days after recovery] or Recovery without PD. PD required one of the following: 50% increase in the absolute number of circulating lymphocytes, Appearance of new palpable lymph nodes, 50% increase in the longest diameter of any previous site of lymphadenopathy, 50% increase in the enlargement of the liver and/or spleen or Transformation to a more aggressive histology. |
