The primary objective is to demonstrate an improvement of the 2-year Event Free Survival (EFS) in DLBCL CD20+ patients aged from 18 to 60 years with 1 to 3 adverse prognostic factors of the aa-IPI treated with GA101 or Rituximab in combination with ACVBP14 or CHOP14 in a PET-driven strategy. |
|
E.2.2 | Secondary objectives of the trial |
- Early metabolic response rate according to PET after 2 and 4 cycles
- Overall Response rate and Best Overall Response after 4 cycles and at end of treatment according to Cheson 2007 (CR, CRu and PR) criteria
- Overall Response rate and Best Overall Response after 4 cycles and at end of treatment according to Cheson 1999 (CR, CRu and PR) criteria.
- Safety of the two antibodies (Rituximab vs GA101) and of the two chemotherapy regimen in the whole population and in the two arms of treatment (R-ACVBP14 vs GA101-ACVBP14 and R-CHOP14 vs GA101-CHOP14).
- Duration of response, progression-free survival and overall survival in the whole population, in the two inductive arms (R-Chemo14 vs GA101-Chemo14)
|
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
- Analysis on blood samples and on tumor tissue biopsy to determine biological factors of the patients and their tumors that influence treatment response based on PET assessment and prognosis.
- Focus on subpopulation: Duration of response, PFS and OS will be performed according to treatment arms (R-Chemo14 vs GA101-Chemo14) on different analysis populations: Population with a ΔSUVmaxPET0-2≤66%, population with a ΔSUVmaxPET0-2>66%, patents submitted to autologous stem cell transplant (PFS and OS only)
- Stem cell harvest evaluation after GA101 treatment

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is the Event Free Survival (EFS) |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
EFS will be defined as the period from the date of randomization until the date of first occurrence of an event. An event is defined as:
- PET positivity according to ΔSUVmax criteria after 2 or 4 induction cycles, as defined by RAC (based on central PET review),
- Progression or relapse, according to Cheson 2007
- Modification of planned treatment non-related to progression, including radiotherapy.
- Death of any cause.
|
|
E.5.2 | Secondary end point(s) |
• Early metabolic response according to PET after 2 and 4 cycles
• Overall Response rate and Best overall response after 4 cycles and end of treatment according to Cheson 2007 criteria
• Overall Response Rate and Best overall response after 4 cycles and end of treatment according to Cheson 1999 criteria
• Duration of response (DoR)
• Progression-Free Survival (PFS)
• Overall survival (OS) |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Response will be assessed after 4 cycles and again at the end of treatment, based on RAC assessment for PET 4 and investigator assessment for EoT PET.
Response will be assessed after 4 cycles and at the end of treatment, based on investigator assessment.
Duration of response is defined as the period from the time of attainment a CR or PR to the date of progression, relapse or death from any cause.
Progression-Free Survival is defined as the period from the date of randomization to the date of first documented disease progression, relapse, or death from any cause.
Overall survival is defined as the period from the date of randomization to the date of death from any cause. |
