Obinutuzumab in marginal zone lymphoma - A MULTICENTER OPEN LABEL SINGLE-ARM PHASE II STUDY (OLYMP-1)
EU CTIS ID: 2024-517476-38-00
What this study is testing
The objective of the trial is to test the efficacy and toxicity of first line treatment with single agent Obinutuzumab in patients with MZL in need of treatment, who have failed or are not eligible for local therapy. For efficacy the rate of complete remissions (according to the GELA criteria for gastric MALT or to the Cheson 2007 criteria for nodal and splenic MZL) after induction therapy will be primarily analysed. For toxicity treatment associated adverse events, quality of life and cumulative incidence of secondary malignancies will be documented.

Who can take part
You may be able to join if
- Confirmed CD20 positive de novo MALT Lymphoma following or being not eligible for local therapy (including surgery, radiotherapy) and antibiotics for H. pylori-positive gastric lymphoma arisen at any extranodal site OR Confirmed CD20 positive de novo splenic MZL following or not being eligible for local therapy (including surgery and antiviral therapy for Hepatitis C Virus) with symptomatic disease OR Confirmed CD20 positive de novo nodal MZL Tissue diagnostic procedures must be performed within 12 months prior to study entry and have to include diagnostics by a reference pathology center. Biopsy material from an excisional or core biopsy must be submitted for retrospective central confirmation. Tissue samples dated > 12 months prior to informed consent can be accepted only if tissue material is available for retrospective confirmation, if there is no clinical indication for transformation of disease, and if the request for additional biopsy would be unethical treatment of the patient. In patients with splenic MZL without splenic tissue available for histologic review, the diagnosis may be confirmed by the presence of splenomegaly and typical morphologic and immunophenotypic findings in the blood and bone marrow. Bone marrow must be submitted for retrospective central confirmation.
- Serum creatinine ≤ 2mg/dl
- Negative HIV antibody
- Pregnancy β-HCG negative. For women of child-bearing potential only; serum or urine β-HCG must be negative during screening and at study enrolment visit (Day 1 of Cycle 1, defined as the day of the first dose of OBINUTUZUMAB)
- Premenopausal fertile females must agree to use a highly effective method of birth control for the duration of the therapy up to 18 months after end of therapy. A highly effective method of birth control is defined as those which result in a low failure rate (i.e. less than 1% per year) when used consistently and correctly such as implants, injectables, combined oral contraceptives, some IUDs, sexual abstinence or vasectomised partner. Post-menopausal (a practical definition accepts menopause ≥ 1 year without menses with an appropriate clinical profile, e.g. age >45 years in the absence of hormone replacement therapy (HRT). In questionable cases, the subject must have a follicle stimulating hormone (FSH) value >40 mIU/mL and an estradiol value < 40pg/mL).
- Men must agree not to father a child for the duration of therapy and 6 months after and must agree to advice a female partner to use a highly effective method of birth control.
You likely can't join if
- ECOG performance status >2
- Patients positive for HBV infection. Patients with occult or prior HBV infection (defined as negative HBsAg and positive total HBcAb) may be included if HBV DNA is undetectable, provided that they are willing to undergo monthly DNA testing. Patients who have protective titers of HBSAb after vaccination or prior but cured hepatitis B are eligible. •
- Patients positive for HCV infection. Patients positive for HCV antibody are eligible only if PCR is negative for HCV RNA.
- History of anaphylaxis in association with previous administration of monoclonal antibodies.
- Vaccination with a live vaccine within 28 days prior to start of therapy
- Treatment with any other investigational agent within 30 days or within 5 x the half life (t1/2) of the investigational product, whichever is longer, or participating in another trial within 30 days prior to entering this study
