Summary

For marginal zone lymphoma (MZL) Rituximab in combination with conventional chemotherapy are widely used for those patients who fail local therapy or do not qualify for such. Depending on the MZL subtype Rituximab/chemotherapy is able to induce in part long remissions, but do not prevent relapse later on. In addition, chemotherapy associated toxicity is often problematic in MZL patients, who are mostly of advanced age. Thus, chemotherapy - free approaches are highly attractive for this patient group. Rituximab single agent is a widely used chemotherapy - free approach in MZL, but was significantly inferior compared to Rituximab/chlorambucil in a large randomized prospective clinical trial in treatment nave MZL with a CR rate of 56 % vs. 80%, respectively (P<0.001).Thus, it is the major aim to develop chemotherapy - free approaches for MZL, which approach efficacy of rituximab/chemotherapy combinations, but avoid chemotherapy associated toxicities. This in particular important in MZL as many physicians are reluctant to treat these often elderly patients with more intense treatments and prefer single agent therapies in these very often well and long responding lymphoma subtype. The type II anti-CD20 antibody Obinutuzumab (OBINUTUZUMAB) has demonstrated remarkable activity in follicular lymphoma and superiority to Rituximab in combination with chemotherapy in treatment nave (Gallium trial) and rituximab refractory follicular lymphoma (Gadolin trial) as well as in CLL in combination with chlorambucil. Based on these observations it is the aim of this study to test the toxicity and efficacy of the anti-CD20 antibody Obinutuzumab (OBINUTUZUMAB) in patients with newly diagnosed MZL in need of treatment, who are not eligible or failed local therapy, following the assumption that this novel anti-CD20 antibody is significantly more effective than Rituximab single agent therapy, and avoids chemotherapy - related toxicity.

Description

For marginal zone lymphoma (MZL) Rituximab in combination with conventional chemotherapy are widely used for those patients who fail local therapy or do not qualify for such.

This in particular important in MZL as many physicians are reluctant to treat these often elderly patients with more intense treatments and prefer single agent therapies in these very often well and long responding lymphoma subtype. The type II anti-CD20 antibody Obinutuzumab (OBINUTUZUMAB) has demonstrated remarkable activity in follicular lymphoma and superiority to Rituximab in combination with chemotherapy in treatment nave (Gallium trial) and rituximab refractory follicular lymphoma (Gadolin trial) as well as in CLL in combination with chlorambucil. Based on these observations it is the aim of this study to test the toxicity and efficacy of the anti-CD20 antibody Obinutuzumab (OBINUTUZUMAB) in patients with newly diagnosed MZL in need of treatment, who are not eligible or failed local therapy, following the assumption that this novel anti-CD20 antibody is significantly more effective than Rituximab single agent therapy, and avoids chemotherapy - related toxicity. For efficacy the rate of complete remissions (according to the GELA criteria for gastric MALT or to the Cheson 2007 criteria for non-gastric extranodal, 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.

The study is a multicenter, single-arm, open-label, phase II trial of 6 cycles of Obinutuzumab in the induction phase followed by a maintenance phase for a maximum of 12 infusions of Obinutuzumab every 8 weeks in patients aged 18 years with previously untreated MZL in need of treatment.

The study flow will be as follows:

  • Previously untreated patients will be screened for eligibility for the trial. If the patient is eligible for the study, the patient will be registered before the first cycle of induction treatment.
  • Patients who progress at any time point during induction are considered as treatment failure. They will be followed up for overall survival until death.
  • Patients, who achieve at least a SD after induction treatment will be eligible to receive maintenance therapy with Obinutuzumab.

It is expected that a total of 56 patients at approximately 20 investigator sites will be registered. Every patient will receive treatment over a time period of 6 x 4 weeks, followed by a maintenance phase of every 8 weeks for a maximum of 12 infusions until progression or study drug - related intolerable toxicity. Patient will be monitored every 3 months for 2 additional years, subsequently every 6 months for three additional years.

Eligibility

Yes No Not Sure

Inclusion Criteria

Patients must have a proven pathological diagnosis of MZL
Patients must meet all of the following inclusion criteria to be eligible for
participation in this study
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
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
Confirmed CD20 positive de novo nodal MZL
Patients in need of treatment
For patients with symptomatic splenic, nodal, or non-gastric extranodal MZL
disease that is de novo or has relapsed following local therapy (i.e., surgery
or radiotherapy) and requires therapy, as assessed by the investigator
For patients with symptomatic gastric extranodal MZL: Helicobacter pylori-
negative disease that is de novo or has relapsed following local therapy
(i.e., surgery or radiotherapy) and requires therapy, as assessed by the
investigator, or H. pylori-positive disease that has remained stable
progressed, or relapsed following antibiotic therapy and requires therapy, as
assessed by the investigator - At least one bi-dimensionally measurable lesion
(> 2 cm in its largest dimension by CT scan or MRI)
In patients with splenic MZL, an enlarged spleen on CT scan or extending at
least 2 cm below the costal margin by physical examination will constitute
measurable disease providing that no explanation other than lymphomatous
involvement is likely. For an enlarged liver to constitute the only measurable
disease parameter, a liver biopsy showing proof of NHL in the liver is
required
For SMZL
Bulky progressive or painful splenomegaly
one of the following symptomatic/progressive cytopenias : Hb < 10 g/dL, or Plat < 80.000 /microL, or neutropenia < 1000 /microL, whatever the reason (autoimmune or hypersplenism or bone marrow infiltration)
enlarged lymphoadenopathy or involvement of extranodal sites with or without cytopenia
splenectomised patients with rapidly raising lymphocyte counts, development of lymphadenopathy or involvement of extranodal sites
SMZL with concomitant hepatitis C infection who have not responded to or are relapsed after Interferon and/or Ribavirin (patients positive for HCV antibody are eligible only if PCR is negative for HCV RNA
For gastric MALT Lymphoma
H. pylori-negative cases following or being not eligible for local therapy (i.e., surgery, radiotherapy or antibiotics)
Others
Age greater than 18 years
Life expectancy >3 months
Baseline platelet Count 50, 109/L, if not due to BM Infiltration by the lymphoma, absolute neutrophil Count 0.75, 109/L
