Copanlisib and Rituximab in Marginal Zone Lymphoma Patients

You may not be if

• 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 (acceptable up to 12 weeks before start of treatment) 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 nodal MZL and extragastric MALT lymphoma:
• \- At least one bi-dimensionally measurable lesion (≥ 1.5 cm in its largest dimension by CT scan or MRI). Please refer to Appendix C.
• For SMZL:
• For splenic MZL, an enlarged spleen on CT scan and lymphoma cell infiltration has to be seen in bone marrow and/or peripheral blood. Please refer also to Appendix E.
• At least one of the following criteria must be met:
• Bulky progressive or painful splenomegaly
• one of the following symptomatic/progressive cytopenias: Hb \< 10 g/dL, or Plat \< 80.000 /µL, or neutropenia \< 1000/µL, whatever the reason (autoimmune or hypersplenism or bone marrow infiltration)
• SMZL with concomitant hepatitis C infection which has not responded to or has relapsed after Interferon and/or Ribavirin and/or direct antiviral agents (patients positive for HCV antibody are eligible only if PCR is negative for HCV RNA).
• splenectomised patients with rapidly raising lymphocyte counts, development of lymphadenopathy or involvement of extranodal sites if not being eligible for local therapy.
• For gastric MALT lymphoma:
• For gastric MALT lymphoma, the clinical evidence of the MZL as seen by gastroendoscopy is sufficient. There is no need to show a measurable lesion by CT scan or MRI. Please refer to Appendix D.
• Inclusion is possible for patients with:
• H. pylori-positive disease that has remained stable, progressed, or relapsed following antibiotic therapy.
• Others:
• Age \>= 18 years
• Life expectancy \>3 months.
• Baseline platelet Count \>= 50 x 109/L (if not due to BM infiltration by the lymphoma), absolute neutrophil Count \>= 0.75 x 109/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)
• GFR ≥ 40 mL/min/1.73 m²
• 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.
• Pregnancy β-HCG negative. For women of child-bearing potential only (i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilisation methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy); serum or urine β-HCG must be negative during screening and at study enrolment visit
• 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 combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal or transdermal), progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable or implantable), intrauterine device (IUD), intrauterine hormone-releasing system ( IUS), bilateral tubal occlusion, vasectomised partner or sexual abstinence. Contraception and pregnancy testing are required according the CTFG recommendations (http://www.hma.eu/fileadmin/dateien/Human\_Medicines/01-About\_HMA/Working\_Groups/CTFG/2014\_09\_HMA\_CTFG\_Contraception.pdf).
• Men must agree not to father a child for the duration of therapy and 6 months after (use of a condom) and must agree to advice a female partner to use a highly effective method of birth control.
• Willingness and ability to comply with scheduled visits, drug administration plan, imaging studies, laboratory tests, other study procedures, and study restrictions.
• Evidence of a personally signed informed consent indicating that the subject is aware of the neoplastic nature of the disease and has been informed of the procedures to be followed, the experimental nature of the therapy, alternatives, potential benefits, possible side effects, potential risks and discomforts, and other pertinent aspects of study participation.
• The presence of any of the following will exclude a subject from enrolment:
• ECOG performance status ≥ 2
• History of a non-lymphoid malignancy except for the following: adequately treated local basal cell or squamous cell carcinoma of the skin, cervical carcinoma in situ, superficial bladder cancer, asymptomatic prostate cancer without known metastatic disease and with no requirement for therapy or requiring only hormonal therapy and with normal prostate specific antigen for ≥1 year prior to study enrollment visit, other Stage 1 or 2 cancer treated with a curative intent and currently in complete remission, for ≥3 years.
• Central nervous system lymphoma, leptomeningeal lymphoma, or histologic evidence of transformation to a high-grade or diffuse large B-cell lymphoma.
