The purpose of this study is to determine the efficacy of SyB L-0501 in combination with rituximab in patients with relapsed/refractory diffuse large B-cell lymphoma.

Primary Objective is to determine the efficacy, as measured by overall response rate on the basis of Revised Response Criteria for Malignant Lymphoma, of SyB L-0501 at 120 mg/m\^2/day on day2 and 3 in combination with rituximab at 375 mg/m\^2 on day 1 of each 21-day cycle in patients with relapsed/refractory diffuse large B-cell lymphoma.

A Multinational, Multicenter, Open-Label Phase II Study of SyB L-0501 in Combination With Rituximab in Patients With Relapsed/Refractory Diffuse Large B-Cell Lymphoma

CR: Disappearance of all evidence of disease. PR: Regression of measurable disease and no new sites.

For the criteria for CR, See Outcome measure 2 description.

The criteria for PR is as below.

Nodal Masses:

more than 50% decrease in sum of the product of the perpendicular diameters (SPD) of up to 6 largest dominant masses; no increase in size of other nodes

1. FDG-avid or PET positive prior to therapy; one or more PET positive at previously involved site
2. Variably FDG-avid or PET negative; regression on CT

Spleen, Liver:

more than 50% decrease in SPD of nodules (for single nodule in greatest transverse diameter); no increase in size of liver or spleen

Bone Marrow:

Irrelevant if positive prior to therapy; cell type should be specified

The criteria for CR is as below

Nodal Masses:

1. fluorodeoxy glucose (FDG)-avid or positron emission tomography (PET) positive prior to therapy; mass of any size permitted if PET negative
2. Variably FDG-avid or PET negative; regression to normal size on computed tomography (CT)

Spleen, Liver:

Not palpable, nodules disappeared

Bone Marrow:

Infiltrate cleared on repeat biopsy; if indeterminate by morphology, immunohistochemistry should be negative

PFS = day of the first PFS event - day of start of study treatment + 1

The definitions of PFS event are as below.

1. PD according to overall response on the basis of Revised Response Criteria for Malignant Lymphoma

   PD: Any new lesion or increase by ≥50% of previously involved sites from nadir. Nodal masses; Appearance of a new lesion(s) \>1.5 cm in any axis, ≥50% increase in SPD of more than one node, or ≥50% increase in longest diameter of a previously identified node \>1 cm in short axis. Lesions PET positive if FDG-avid lymphoma or PET positive prior to therapy. Spleen, Liver; ≥50% increase from nadir in the SPD of any previous lesions. Bone marrow; New or recurrent involvement
2. Disease progression during treatment period
3. Disease progression during follow up period
4. Start of treatment of new lesion
5. Occurrence of other multiple malignant tumors
6. Death

Abnormalities in laboratory test values in overall study period were analyzed. Severity of abnormalities were evaluated using Common Terminology Criteria for Adverse Events (CTCAE).

grade 1 : mild grade 2 : moderate grade 3 : severe grade 4 : life threatening or disabling grade 5 : death related to adverse event

The criteria for Clinical Stage (Ann Arbor staging) are as below:

I: involvement of a single nodal region. II: involvement of 2 or more lymph node regions on the same side of the diaphragm. III: involvement of lymph node regions on both sides of the diaphragm. IV: disseminated involvement of 1 or more extra-lymphatic sites with or without associated lymph node involvement
