2. Histologically confirmed diagnosis of CD20 positive iNHL, with histological subtype limited to:
- Follicular lymphoma (FL) grade 1-2-3a
- Small lymphocytic lymphoma (SLL) with absolute lymphocyte count <5x109/L at the time of diagnosis and at study entry

3. Patients must have relapsed after at least 1 prior line of therapy, including rituximab and alkylating agents. A previous regimen is defined as one of the following: at least 2 months of single-agent therapy; at least 2 consecutive cycles of polychemotherapy; autologous transplant; radioimmunotherapy. Patients must be not refractory to rituximab at any prior line of therapy (response shorter than 6 months from the end of any prior rituximab- containing treatment) but can be refractory to any non-rituximab containing regimen. Previous exposure to PI3K is acceptable provided there is no resistance (see also exclusion criterion 40).

4. Non-WM patients must have at least one bi-dimensionally measurable lesion (which has not been previously irradiated) according to the Lugano Classification.

Primary Outcome(s)

Timepoint(s) of evaluation of this end point: Time (in days) from randomization to PD or death from any cause (if no progression is documented). The actual date of tumor assessments will be used for this calculation. PFS for patients without PD or death at the time of analysis will be censored at the date of their last tumor evaluation. PFS for patients who have neither tumor assessments nor death after baseline will be censored at Day 1.

Primary end point(s): Progression free survival (PFS)

Main Objective: The primary objective of this study is:
- 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 alkylating agents, and who either had a treatment-free interval of =12 months after completion of the last rituximab-containing treatment, or for whom chemotherapy is contraindicated on reason of age, comorbidities, and/or residual toxicity.

Secondary Objective: The secondary objectives of this study are to evaluate:
• The following characteristics of disease-related symptoms: “time to deterioration” and “time to improvement”
• Other radiological and clinical indicators of treatment efficacy
• Safety and tolerability of copanlisib

The other objectives of this study are to evaluate:
- Pharmacokinetics
- Biomarkers
- Quality of life

Secondary Outcome(s)

Timepoint(s) of evaluation of this end point: - ORR - assessed in all patients up to the time of analysis of PFS.
- DOR: time (in days) from first observed tumor response (CR, VGPR, PR, or MR) until PD or death from any cause, whichever is earlier
- CRR: assessed in all patients up to the time of analysis of PFS.
- TTP: time from randomization to PD or death related to PD, whichever is earlier
- OS: time (in days) from randomization until death from any cause.
- Time to deterioration in DRS-P of at least 3 points, as measured by the FLymSI-18 questionnaire.
- Time to improvement in DRS-P of at least 3 points, as measured by the FLymSI-18 questionnaire, will be evaluated for patients with a baseline DRS-P score of 30 points or less.

Secondary end point(s): - Objective tumor response rate (ORR)
- Duration of response (DOR)
- Complete response rate (CRR)
- Time to progression (TTP)
- Overall survival (OS)
- Time to deterioration in DRS-P
- Time to improvement in DRS-P
