Resumen

The purpose of this study was to evaluate whether copanlisib in combination with rituximab is superior to placebo in combination with rituximab in prolonging progression free survival (PFS) in patients with relapsed iNHL who have received one or more lines of treatment, including rituximab and who either had a treatment-free interval of ≥ 12 months after completion of the last rituximab-containing treatment, or who are unwilling to receive chemotherapy/for whom chemotherapy is contraindicated on reason of age, comorbidities, and/or residual toxicity.

Criterios de inclusión

Histologically confirmed diagnosis of Indolent non-Hodgkin's lymphoma (iNHL) in CD20 positive patients, with histological subtype limited to:
Follicular lymphoma(FL) grade1-2-3a
Small lymphocytic lymphoma(SLL) with absolute lymphocyte count \<5x10\*9/L at study entry
Lymphoplasmacytoid lymphoma/Waldenström macroglobulinemia (LPL/WM)
Marginal zone lymphoma (MZL) (splenic, nodal, or extra-nodal)
Patients must have relapsed (recurrence after complete response or presented progression after partial response) after the last rituximab-, rituximab biosimilars-, or anti-CD20 monoclonal antibody (e.g. obinutuzumab)-containing therapy (other previous treatment lines after rituximab are allowed). A previous regimen is defined as one of the following: at least 2 months of single-agent therapy (less than 2 months of therapy is allowed for patients who responded to single-agent rituximab, rituximab biosimilars, or anti-CD20 monoclonal antibody); at least 2 consecutive cycles of polychemotherapy; autologous transplant; radioimmunotherapy. Previous exposure to PI3K is acceptable (except to copanlisib) provided there is no resistance. Patients with prior intolerance to PI3K inhibitors other than copanlisib are eligible.
Non-WM must have at least one bi-dimensionally measurable lesion (which has not been previously irradiated) according to the Lugano Classification. For patients with splenic MZL (Marginal-zone lymphoma) this requirement may be restricted to splenomegaly alone since that is usually the only manifestation of measurable disease.
Patients affected by WM who do not have at least one bi-dimensionally measurable lesion in the baseline radiologic assessment must have measurable disease, defined as presence of immunoglobulin M (IgM) paraprotein with a minimum IgM level ≥ 2 x upper limit of normal (ULN) and positive immunofixation test .
Male or female patients ≥ 18 years of age
Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2
Life expectancy of at least 3 months
Availability of fresh tumor tissue and/or archival tumor tissue for central pathology(obtained within 5 years of the consent date) at Screening
Adequate baseline laboratory values collected no more than 7 days before starting study treatment
Left ventricular ejection fraction ≥ 45%
Patients must either:
have had a progression-free and treatment-free interval of at least 12 months after completion of the rituximab-, rituximab biosimilars-, or anti-CD20 monoclonal antibody-containing treatment OR
be considered unfit to receive chemotherapy on reason of age, concomitant morbidities, and/or residual toxicity from previous treatments, or unwillingness to receive chemotherapy. These patients must also have had a progression-free and treatment-free interval of at least 6 months after completion of the last rituximab-, rituximab biosimilars-, or anti-CD20 monoclonal antibody-containing treatment. Patients in whom chemotherapy is contraindicated are defined by one of the following features:
Age ≥ 80 years
Age \< 80 years and at least 1 of the following conditions:
at least 3 grade 3 CIRS-G comorbidities OR
at least 1 grade 4 CIRS-G comorbidity (if compatible to participation in the study).

Criterios de exclusión

Histologically confirmed diagnosis of follicular lymphoma grade 3b or transformed disease, or chronic lymphocytic leukemia
Progression free interval or treatment free interval of less than 12 months since the last rituximab-, rituximab biosimilars-, or anti-CD20 monoclonal antibody (e.g. obinutuzumab)-containing treatment(including maintenance with these drugs). For patients considered unwilling/unfit to receive chemotherapy : progression free interval or treatment free interval of less than 6 months since the last rituximab-, rituximab biosimilars-, or anti-CD20 monoclonal antibody-containing treatment (including maintenance with these drugs), as assessed by the investigator
History or concurrent condition of interstitial lung disease of any severity and/or severely impaired lung function
Known lymphomatous involvement of the central nervous system
Patients with HbA1c \> 8.5% at Screening
Known history of human immunodeficiency virus (HIV) infection
Hepatitis B (HBV) or hepatitis C (HCV). Patients positive for HBsAg or HBcAb will be eligible if they are negative for HBV-DNA, these patients should receive prophylactic antiviral therapy. Patients positive for anti- HCV antibody will be eligible if they are negative for HCV-RNA
Documented evidence of resistance to prior treatment with idelalisib or other PI3K inhibitors.
Prior treatment with copanlisib
Cytomegalovirus (CMV) infection. Patients who are CMV PCR positive at baseline will not be eligible.

Intervenciones

drug

Copanlisib (Aliqopa, BAY80-6946)

Copanlisib is supplied as lyophilized preparation in a 6 mL injection vial. The total amount of copanlisib per vial is 60 mg. The solution for IV infusions is obtained after reconstitution with normal saline solution. Dosing will be administered on Days 1, 8 and 15 of each 28-day cycle. Copanlisib will be administered before rituximab.

drug

Placebo

Placebo is supplied as lyophilized preparation in a 6 mL injection vial. The developed placebo lyophilisate is equivalent to the 60 mg copanlisib formulation, with regard to the composition of excipients and the instructions for reconstitution and dose preparation. Placebo dosing will be administered on Days 1, 8 and 15 of each 28-day cycle. Placebo will be administered before rituximab.

drug

Rituximab

Rituximab dose 375 mg/m2 body surface weekly during Cycle 1 on Days 1, 8, 15 and 22, and then on Day 1 of Cycles 3, 5, 7 and 9.The solution for IV infusions is obtained after reconstitution of a calculated concentration of 1 to 4 mg/ml rituximab into an infusion bag containing sterile, pyrogen-free sodium chloride 9 mg/ml (0.9%) solution for injection or 5% D-Glucose in water.
