E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Primary objective of the study is to demonstrate high level of biosimilarity between MabionCD20 (MABION SA) and the reference product: MabThera (rituximab by Hoffman-La Roche) in patients with CD20-positive diffuse large B-cell lymphoma, based on the percentage of patients achieving the primary pharmacokinetic endpoints. |
|
E.2.2 | Secondary objectives of the trial |
To demonstrate high level of biosimilarity between MabionCD20 (MABION SA) and the reference product MabThera (rituximab by Hoffman-La Roche) in patients with CD20-positive diffuse large B-cell lymphoma based on comparative analysis of the pharmacodynamic parameters, pharmacokinetic parameters, the percentage of patients achieving the efficacy endpoints, comparative safety and immunogenicity. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients with histological confirmed CD20 positive diffuse large B cell lymphoma (DLBCL); Patients that had been diagnosed according to the WHO classification; Performance status ≤ 2 on the ECOG/WHO scale, performance status of 3 will be accepted if impairment is caused by DLBCL complications and improvement is expected once therapy is initiated; Patients eligible for rituximab treatment according to MabThera indications. Life expectance at least 6 months; No prior immunotherapy for DLBCL; Laboratory values within normal range unless abnormalities are related to lymphoma. A negative serum or urine pregnancy test prior to treatment. |
|
E.4 | Principal exclusion criteria |
Life expectance less than 6 months; Any chemotherapy, radiotherapy, immunotherapy, biologic, investigational or hormonal therapy for treatment of lymphoma within 28 days prior to treatment; Prior rituximab, other anti-CD20 mAb drug treatment, previous treatment with any cell depleting therapies (e.g., anti-CD4, anti-CD5, anti-CD3, anti-CD19, anti CD11a, anti-CD22, BLys/BAFF). Secondary lymphoma after previous chemotherapy or radiotherapy; History of other invasive malignancy within 5 years except for localized/in situ carcinomas such as non-melanoma skin cancer or cervical carcinoma in situ; Primary or secondary immunodeficiency; Evidence of significant uncontrolled concomitant disease such as, but not limited to, nervous system, renal, hepatic, endocrine, or gastrointestinal disorders which, in the Investigator's opinion, would preclude subject participation; Active infections: known active bacterial, viral, fungal, mycobacterial, other infection (including tuberculosis, sepsis, opportunistic infections) but excluding fungal infections of nail beds; III or IV class of the New York Heart Association (NYHA) Classification; Pregnancy or lactation (negative serum pregnancy test for women of child bearing age); Recent vaccination (< 4 weeks prior treatment); |
