In clinical study A (Clin A) we are planning to evaluate the efficacy and the feasibility of an intensified chemo-immunotherapy program including auto-SCT or RIC allo-SCT in advanced stage PTCL pts ≥ 18 and \< or = 60 years.
In clinical study B (Clin B) we intend to verify the efficacy and the feasibility of a combined immuno-chemotherapy approach in a subset of elderly pts aged \> 60 and \< or = 75 years.
