简要总结
This is an open-label, multicenter, randomized phase III trial. The study plans to randomize patients with a 1 to 1 ratio to Arm A (Standard arm) or Arm B (Experimental arm).
All patients of both arms will receive a prephase with oral prednisone before 6 cycles Q21 of immunochemotherapy with R-CHOP or R-miniCHOP at standard doses; patients in the Experimental arm (Arm B) will receive also a prephase therapy with VitD and a supplementation of VitD during the intere period of immunochemotherapy according to a prefixed schedule. Choice of type of immunochemotherapy will not rely on Comprehensive Geriatric Assessment result, but treatment at reduced doses with R-miniCHOP is highly recommended option for UNFIT and FRAIL patients.
详细描述
After the patient signs the written informed consent the patient will enter the screening phase planning baseline assessments and will be randomly allocated with a 1 to 1 ratio to Arm A (Standard arm) or Arm B (Experimental arm).
Patients randomized to Arm A will receive a prephase with oral prednisone (50 mg for 7 days [day -6 to day 0]) followed by 6 courses of R-CHOP or R-miniCHOP every 21 days.
If patients randomized to arm A are already on VitD, they are allowed to continue receiving VitD supplementation at a dose that can be considered part of the standard of care and does not exceed the maximum standard VitD dose recommended for general adult and elderly population , up to 10,000 U/week VitD .
If clinically indicated at treating physician judgement, patients could receive 1 mg of vincristine on the first day of prephase ; in this case vincristine administration in cycle 1 of immunochemotherapy should be skipped, in patients receiving R-miniCHOP; reduced to 1 mg, in patients receiving R-CHOP.
Patients randomized to Arm B will receive a prephase with oral prednisone and a prephase therapy with VitD according to the below reported schedule followed by 6 courses of R-CHOP or R-miniCHOP every 21 days.
