E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
In Part 3 of this study, up to 100 subjects with relapsed/refractory diffuse large B-cell lymphoma (DLBCL) will be treated with 50 μg/kg/dose of MT-3724, and the primary objective will be to:
Determine the efficacy of MT-3724 as monotherapy in subjects with relapsed or refractory DLBCL based on the overall response rate (ORR) by the revised Lugano Classification for Lymphoma adjusted according to LYRIC (lymphoma response to immunomodulatory therapy criteria) hereinafter referred to as “revised Lugano Criteria” (Cheson et al, 2014, 2016).
o Overall response rate is defined as the proportion of subjects with either a complete response (CR) or a partial response (PR) as determined by independent, blinded central review. |
|
E.2.2 | Secondary objectives of the trial |
Safety
Efficacy based on the
o overall response rate (ORR)
defined as the proportion of subjects with either a CR or a PR as determined by investigator assessment.
o duration of tumor response (DOR),
Time from initial documentation of tumor response (PR or CR) to disease progression
o disease control rate (DCR),
Percentage of subjects who have achieved CR, PR and SD (defined as SD for 3 months or longer).
o progression-free survival (PFS)
PFS is defined as the time from study enrollment to the earliest date of disease progression or death from any cause.
o overall survival (OS)
Overall survival is defined as the time from study enrollment to death from any cause

|
|
E.4 | Principal exclusion criteria |
• Received anti-CD20 MAb within 84 days before the start of treatment
• Subjects who have received anti-CD20 Mab must have levels below a specified threshold to be eligible for study participation
• Received approved or investigational treatment for NHL, including radiation therapy to target tumor lesions, within 4 weeks before the start of treatment
• Received systemic immunosuppressive agents (except prescribed corticosteroids at doses ≤20 mg/day prednisone equivalent) within 2 weeks before the start of treatment
• Received any vaccines except injectable flu vaccine (inactivated or recombinant) within 4 weeks before the start of treatment
• Received allogeneic stem cell transplant
• Evidence of seropositive status for human immunodeficiency virus (HIV), hepatitis B virus (positive for hepatitis B surface antigen (HBsAg) or anti-HBsAg and anti-HBcAg antibodies) or hepatitis C virus (positive for anti-HCV antibody or HCV-RCV-RNA quantitation) at screening
• History of cardiovascular, renal, hepatic or any other disease within ≤3 months before the start of treatment that in the investigator’s opinion, may increase the risks associated with study participation or require treatments that may interfere with the conduct of the study or the interpretation of study results
• History of another primary malignancy within the past 3 years (except for ductal breast cancer in situ, non-melanoma skin cancer, prostate cancer not requiring treatment, and cervical carcinoma in situ)
• Current evidence of new or growing brain or spinal metastases during screening
