Permanent sterilization methods include but are not limited to hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A postmenopausal state is defined as no menses for continuous 12 months without an alternative medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy. The investigator or a designated associate is requested to advise the patient how to achieve highly effective birth control (failure rate of less than 1%), e.g., intrauterine device (IUD), intrauterine hormone-releasing system (IUS), bilateral tubal occlusion, vasectomized partner and sexual abstinence.

Objective:
To see if copanlisib plus rituximab is effective at slowing the growth of FL.
Eligibility:
People with FL who have not had prior treatment for their disease
Design:
Participants will be screened with:
- Medical and cancer history
- Physical exam
- Review of symptoms and ability to perform daily activities
- Blood and urine tests
- Small amount of bone marrow removed by needle in the hip bone
- Scans of the chest, abdomen, and pelvis. Some scans will use a radioactive tracer.
Participants will get the study drugs in 28-day cycles for up to 13 cycles. Both are given as an intravenous (IV) infusion. Copanlisib is given over about 1 hour. Rituximab is given over several hours.
- For 1 cycle, they will get 3 weekly doses of copanlisib.
- For the next cycle, they will get 3 weekly doses of copanlisib and 4 weekly doses of rituximab.
- For all other cycles, they will get 2-3 weekly doses of copanlisib and 1 dose of rituximab.
Participants will repeat some screening tests during the cycles. They will give a cheek swab and/or saliva sample and may have a tumor sample taken.
After treatment, some participants will have a few follow-up visits each year for 5 years, then 1 each year. They will repeat screening tests.
Other participants will be contacted by phone every few months.
Read the detailed description
Background:
- Follicular lymphoma (FL) is the most common indolent non-Hodgkins lymphoma (NHL) with a highly variable clinical course across patients
- Standard frontline therapy for FL includes a monoclonal anti-cluster of differentiation 20 (CD20) antibody with or without chemotherapy that can induce durable remissions but is generally not curable
- The 20% of patients who relapse within 2 years of frontline chemotherapy have an inferior overall survival; molecular profiles and gene-expression signatures can identify patients at high-risk of early treatment failure but are incomplete and require further validation
- The phosphoinositide 3-kinase (PI3K) pathway is critically important in FL; agents that target PI3K show good clinical activity in patients who relapse early after chemotherapy
- Copanlisib is an intravenous therapy targeting both PI3K-alpha and PI3K-delta isoforms and is Food and Drug Administration (FDA)-approved for use in adults with relapsed and refractory FL
- Induction therapy with copanlisib and rituximab may produce deep and durable remissions in patients with FL without the use of cytotoxic agents
- Circulating tumor deoxyribonucleic acid (DNA) circulating tumor DNA (ctDNA) is a promising modality for monitoring therapy
Objective:
- To determine the complete response (CR) rate after copanlisib and rituximab as induction therapy for patients with untreated follicular lymphoma
Eligibility:
- Patients with histologically confirmed stage II-IV follicular lymphoma, grade 1-2 or 3a that meet criteria for initiation of systemic therapy
- No previous systemic therapy; prior local radiation permitted
- Eastern Cooperative Oncology Group (ECOG) performance status 0-2
- Adequate bone marrow and organ function
Design:
- Phase 2 study of up to 65 patients with untreated FL who meet standard criteria for treatment
- Patients will first be treated with a window of copanlisib monotherapy, followed by induction therapy with copanlisib and rituximab for up to 6 cycles
- Patients who achieve a CR after 6 cycles of induction therapy will stop treatment and be monitored with computed tomography (CT) scans and plasma assays for circulating tumor DNA (ctDNA). Patients who relapse > 6 months from the end of induction can be re-treated with 6 additional cycles of copanlisib and rituximab
- Patients who achieve a partial response after 6 cycles of induction therapy will receive an additional 6 cycles of extended induction therapy with copanlisib and rituximab
- Patients who do not achieve at least a partial response after 6 cycles of induction therapy will stop treatment and be monitored with CT scans and peripheral blood assays for ctDNA
- Patients who progress or relapse after induction therapy and meet criteria for salvage therapy will be treated with standard chemotherapy and a monoclonal anti-CD20 antibody

What is being measured
The primary outcome is the main question the study is designed to answer.
Proportion of Participants Who Achieve Positron Emission Tomography (PET) - Negative Complete Response
The response rate will be determined and reported along with a 95% confidence interval. Complete Response was assessed by the Lugano Classification of Response Criteria and is defined as the proportion of participants who achieve a PET-negative complete response in accordance with the 2014 Lugano classification of the International Working Group Criteria for Non-Hodgkin's Lymphoma after induction therapy with copanlisib and rituximab. Under the Lugano criteria (2014), a Complete Response is defined by a Deauville score of 1-3 on PET and no evidence of disease in the bone marrow, with or without a residual mass.
Measured: Within 2 months of induction therapy completion, up to 13 months since start of therapy
Secondary outcomes (8)
Proportion of Participants With Serious and/or Non-serious Adverse Events Leading to Discontinuation of Induction Therapy With Copanlisib and Rituximab
The proportion of participants with adverse events leading to discontinuation of induction therapy with copanlisib and rituximab.
Measured: Through study induction therapy period and until 1 month after completion of induction
Proportion of Participants With a Continuous Complete Response Rate at 30 Months (CR30)
The response rate will be determined and reported along with a 95% confidence interval. Complete Response was assessed by the Lugano Classification of Response Criteria and is defined as the proportion of participants who achieve a positron emission tomography (PET)-negative complete response in accordance with the 2014 Lugano classification of the International Working Group Criteria for Non-Hodgkin's Lymphoma after induction therapy with copanlisib and rituximab. CR30 refers to the proportion of participants who remain in complete response at 30 months from study enrollment. Under the Lugano criteria (2014), a Complete Response is defined by a Deauville score of 1-3 on PET and no evidence of disease in the bone marrow, with or without a residual mass.
Measured: Through 30 months from study enrollment
Complete Molecular Remission (CMR) Rate Defined as the Proportion of Participants Who Achieve Both a Complete Response and Are Negative on Molecular Assays for Minimal Residual Disease After Induction Therapy With Copanlisib and Rituximab
The proportion of participants who achieve both a complete response and are negative on molecular assays for minimal residual disease after induction therapy with copanlisib and rituximab. Under the Lugano criteria (2014), a Complete Response is defined by a Deauville score of 1-3 on positron emission tomography (PET) and no evidence of disease in the bone marrow, with or without a residual mass. Minimal residual disease was defined as detection of circulating tumor deoxyribonucleic acid (DNA) after completion of induction therapy in blood.
Measured: Through study induction therapy period and until 1 month after completion of induction
Objective Response Rate (ORR) Defined as the Proportion of Participants Who Achieve at Least a Partial Response (PR) to Induction Therapy With Copanlisib and Rituximab
Objective response rate (ORR) defined as the proportion of participants who achieve at least a partial response (PR) to induction therapy with copanlisib and rituximab. Partial response was defined using the 2014 Lugano classification for lymphoma and defined as a decrease in the sum of the product of the diameters (SPD) of up to six of the largest nodes or nodal masses.
Measured: Through study induction therapy period and until 1 month after completion of induction
Duration of Response (DOR)
DOR is defined as time from first documentation of tumor response to disease progression. Progression was defined as evidence of disease growth, recurrence, or new disease based on imaging (computed tomography (CT) or positron-emission tomography (PET/CT) and clinical evaluation.
Measured: 6 years
Time to Next Treatment (TTNT)
TTNT is the time from the end of induction therapy with copanlisib and rituximab until initiation of next treatment. Induction therapy is combination therapy with copanlisib and rituximab, and next treatment is start of any systemic therapy after completion of induction therapy with copanlisib and rituximab.
Measured: time from the end of induction therapy with copanlisib and rituximab until initiation of next treatment, up to 6 years
Progression Free Survival (PFS)
PFS is the time from study enrollment until disease progression or death from any cause. Disease progression was defined as evidence of disease growth, recurrence, or new disease based on imaging (computed tomography (CT) or positron-emission tomography (PET/CT) and clinical evaluation.
Measured: time from study enrollment until disease progression or death from any cause, up to 6 years
Overall Survival (OS)
OS is the time from study enrollment until death from any cause.
Measured: time from study enrollment until death from any cause, up to 6 years

Participants with prolonged QTc at baseline, participants with congenital prolonged QT syndrome, and participants chronically on medications as specified in the protocol will have ECG monitoring after copanlisib window, and every 3 cycles thereafter. | Diagnostic test | Response-Adapted Therapy With Copanlisib and Rituximab in Untreated Follicular Lymphoma |
Primary outcome
Proportion of Participants Who Achieve Positron Emission Tomography (PET) - Negative Complete Response
Time frame: Within 2 months of induction therapy completion, up to 13 months since start of therapy
The response rate will be determined and reported along with a 95% confidence interval. Complete Response was assessed by the Lugano Classification of Response Criteria and is defined as the proportion of participants who achieve a PET-negative complete response in accordance with the 2014 Lugano classification of the International Working Group Criteria for Non-Hodgkin's Lymphoma after induction therapy with copanlisib and rituximab. Under the Lugano criteria (2014), a Complete Response is defined by a Deauville score of 1-3 on PET and no evidence of disease in the bone marrow, with or without a residual mass.
8 secondary outcomes
Proportion of Participants With Serious and/or Non-serious Adverse Events Leading to Discontinuation of Induction Therapy With Copanlisib and Rituximab
Time frame: Through study induction therapy period and until 1 month after completion of induction
Proportion of Participants With a Continuous Complete Response Rate at 30 Months (CR30)
Time frame: Through 30 months from study enrollment
Complete Molecular Remission (CMR) Rate Defined as the Proportion of Participants Who Achieve Both a Complete Response and Are Negative on Molecular Assays for Minimal Residual Disease After Induction Therapy With Copanlisib and Rituximab
Time frame: Through study induction therapy period and until 1 month after completion of induction
Objective Response Rate (ORR) Defined as the Proportion of Participants Who Achieve at Least a Partial Response (PR) to Induction Therapy With Copanlisib and Rituximab
Time frame: Through study induction therapy period and until 1 month after completion of induction
Duration of Response (DOR)
Time frame: 6 years
Time to Next Treatment (TTNT)
Time frame: time from the end of induction therapy with copanlisib and rituximab until initiation of next treatment, up to 6 years
Progression Free Survival (PFS)
Time frame: time from study enrollment until disease progression or death from any cause, up to 6 years
Overall Survival (OS)
Time frame: time from study enrollment until death from any cause, up to 6 years

What is this clinical trial studying?
A Phase 2 study testing Rituximab, Copanlisib and Bone Marrow Aspiration/Biopsy in people with Follicular Lymphoma and Non-Hodgkin's Lymphoma, run by National Cancer Institute (NCI) at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 24 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 3 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 3 Mar 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Proportion of Participants Who Achieve Positron Emission Tomography (PET) - Negative Complete Response (time frame: Within 2 months of induction therapy completion, up to 13 months since start of therapy). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Mar 2026.
