| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial |

| 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 | 
| QT sub-study: included in the main study protocol. Objective: assessment of potential QT prolongation by YM155 during Cycle 1 only. |  | 
| E.3 | Principal inclusion criteria | 
| - Male or female subjects aged 18 years or older. - Histologically confirmed Diffuse Large B-Cell Lymphoma (DLBCL) (including transformed DLBCL) of any stage.
 - Refractory to the last treatment regimen, defined as one of the following:
 o The subject failed to obtain at least a Partial Remission (PR) at anytime while receiving the previous treatment regimen.
 o The subject obtained at least a PR during the previous treatment regimen, but later progressed while still on the treatment regimen.
 o The subject obtained at least a PR to the previous treatment regimen, but progressed within 6 months following completion of the previous treatment regimen.
 - Subjects who have not received an autologous Bone Marrow Tansplant (BMT) or autologous Peripheral Blood Stem Cell Transplant (PBSCT) must have refused or been ineligible for that procedure.
 - At least one measurable lesion defined as superior or equal to 1.5 cm in the longest transverse diameter by CT scan.
 -  No known central nervous system involvement.
 - Eastern Cooperative Oncology Group (ECOG) performance status inferior or equal to 2.
 |  | 
| E.4 | Principal exclusion criteria | 
| - Any therapy for lymphoma within 21 days prior to the first YM155 dose. - Within 4 weeks of the baseline FDG-PET scan, subjects cannot have had the following:
 o Radiation therapy.
 o Surgical procedures (except biopsies and central catheter / port placement).
 o Active infection (bloodstream or deep tissue).
 - Inadequate marrow, hepatic and/or renal function at the Baseline Visit defined as:
 o Serum creatinine superior or equal to 1.5 x Upper Limit of Normal (ULN) or calculated serum creatinine clearance < 60 mL/min.
 o Absolute Neutrophil Count (ANC) inferior or equal to 750/mm3.
 o Platelet inferior or equal to 50,000/mm3.
 o Alanine Transaminase (ALT) and Aspartate Transaminase (AST) superior or equal to 2.5 x ULN; superior or equal to 5 x ULN if secondary to liver metastases.
 - Subjects received > 3 prior treatment regimens for their lymphoma. Subjects are permitted to have had an autologous BMT or autologous PBSCT as one of the prior treatment regimens. If a subject has had an autologous BMT or autologous PBSCT, it, along with any preparative treatment (salvage chemotherapy, high-dose chemotherapy, radiation therapy, etc.) is included as one treatment regimen.
 - Allogeneic BMT or allogeneic PBSCT.
 - History of other malignancy requiring treatment within 5 years, except for treated basal or squamous cell carcinoma of the skin or in situ cervical cancer
