Brief Summary:
For marginal zone lymphoma (MZL) Rituximab in combination with conventional chemotherapy is 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 naïve 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 PI3K inhibitor Copanlisib has shown high clinical activity in indolent B - cell lymphomas among them MZL. Based on these observations it is the aim of this study to test the toxicity and efficacy of Copanlisib in combination with the anti-CD20 antibody Rituximab in patients with newly diagnosed or relapsed MZL in need of treatment, who are not eligible or failed local therapy, following the assumption that this novel chemotherapy - free combination is significantly more effective than Rituximab single agent therapy and at least as efficient as Rituximab/chemotherapy, but avoids chemotherapy - related toxicity.

Detailed Description:

For marginal zone lymphoma (MZL) Rituximab in combination with conventional chemotherapy is 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 naïve 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 PI3K inhibitor Copanlisib has shown high clinical activity in indolent B - cell lymphomas among them MZL.

The objective of the trial is to test the efficacy and toxicity of the treatment of Copanlisib/Rituximab in patients with MZL in need of treatment, who have failed or are not eligible for local therapy or relapsed after local or systemic therapy. 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.

Primary Outcome Measures :
  1. Complete Response [ Time Frame: 12 months ]
    Primary endpoint is the complete response (CR rate (CRR) determined 12 months after start of induction therapy). Patients who progress before 12 months after start of treatment will be treated as CR='NO' and will be included in the calculation of the primary endpoint. No primary endpoint will be determined for patients who withdraw.


Secondary Outcome Measures :
  1. Response rate [ Time Frame: 12 months ]
    The response rates (complete response (CR), partial response (PR)) and overall response rate (CR or PR) are evaluated 4 weeks after the end of induction treatment and 12 months after start of treatment.

  2. Best response [ Time Frame: 8.5 years ]
    Best response is determined in the time interval from the start of induction therapy to end of follow-up.

  3. Time to best response [ Time Frame: 8.5 years ]
    Time to best response is defined as the time from the start of induction to best response the patient achieves (CR, PR).

  4. Time to first response [ Time Frame: 12 months ]
    Time to first response is defined as the time from the start of induction to first response (CR, PR).

  5. Progressioin free survival (PFS) [ Time Frame: 12 months ]
    Progression free survival (PFS) is defined as the time from registration to the first occurrence of progression or relapse as assessed by the investigator, or death from any cause. PFS for patients without disease progression, relapse, or death will be censored at the time of the last tumor assessment.

  6. Time to Treatment failure (TTF) [ Time Frame: 8.5 years ]
    Time to treatment failure (TTF) is defined as the time of registration to discontinuation of therapy for any reason including death from any cause, progression, toxicity or add-on of new anti-cancer therapy. Patients alive without treatment failure are censored at the latest tumor assessment date.

  7. Duration of Response (DR) [ Time Frame: 8.5 years ]
    Duration of response as defined as the period from the first response (at least PR) to treatment until evidence of disease progression, relapse or death of any cause. Patients alive without progression and relapse will be censored at the latest tumor assessment date or the stopping date.

  8. Cause specific survival (CSS) [ Time Frame: 8.5 years ]
    Cause specific survival is defined as the period from the induction registration to death from lymphoma or lymphoma related cause; death unrelated to MZL is considered as a competing event.

  9. Overall survival (OS) [ Time Frame: 8.5 years ]
    Overall survival is defined as the period from the induction registration to death from any cause. Patients who have not died until the time of the analysis will be censored at their last contact date.

  10. Quality of life during induction and maintenance therapy [ Time Frame: 8.5 years ]
    Quality of life will be measured by the FACTLym before start of treatment, during induction and maintenance.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

Patients must meet all of the following inclusion criteria to be eligible for participation in this study:

  • Confirmed CD20 positive MALT Lymphoma de novo or relapsed 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 or relapsed 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 or relapsed 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.

  • 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 (≥ 1.5 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.

Others:

  • Age greater than 18 years
  • Life expectancy greater 3 months. Baseline platelet count 50, 109 pro L if not due to BM infiltration by the lymphoma, absolute neutrophil count 0.75, 109 pro L.
  • Meet the following pretreatment laboratory criteria at the Screening visit conducted within 28 days of study enrollment (unless due to underlying lymphoma):

    • ASAT (SGOT): 3 times the upper limit of institutional laboratory normal value
    • ALAT (SGPT): 3 times the upper limit of institutional laboratory normal value
    • Total Bilirubin: 2 mg/dL or 2 times the upper limit of institutional laboratory normal value, unless clearly related to the disease (except if due to Gilbert's syndrome)
  • Serum creatinine ≤ 2mg/dl
  • Negative HIV antibody
  • Positive test results for chronic HBV infection (defined as positive HBsAg serology): 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.
  • Positive test results for hepatitis C (hepatitis C virus [HCV] antibody serology testing): patients positive for HCV antibody are eligible only if PCR is negative for HCV RNA.

  • Premenopausal fertile females must agree to use a highly effective method of birth control for the duration of the therapy up to 12 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.
  • 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.
