Az obinutuzumab [RO5072759 (GA101)] vizsgálata CHOP kemoterápiával kombinálva olyan betegeknél, akik korábban nem kezeltek előrehaladott diffúz nagy B-sejtes limfómában (GATHER)

2026. szeptember 24. frissítette: Genentech, Inc.

Fázis II., nyílt, többközpontú vizsgálat a hatékonyságról, biztonságról és biomarkerekről olyan betegeknél, akik korábban kezeletlen, előrehaladott diffúz nagy B-sejtes limfómában szenvednek, és GA101-gyel (RO5072759) kezelték CHOP kemoterápiával kombinálva

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
Időkeret: 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
Időkeret: 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.
