Copanlisib With Dose-Adjusted EPOCH-R in Relapsed and Refractory Burkitt Lymphoma and Other High-Grade B-cell Lymphomas

Copanlisib With Dose-Adjusted EPOCH-R in Relapsed and Refractory Burkitt Lymphoma and Other High-Grade B-cell Lymphomas

Phase 1 Study of Copanlisib With Dose-adjusted EPOCH-R in Relapsed and Refractory Burkitt Lymphoma and Other High-Grade B-cell Lymphomas

Background: Burkitt Lymphoma (BL) and diffuse large B-cell lymphoma (DLBCL) are aggressive B cell lymphomas. Frontline treatment does not always work. Researchers want to see if a combination of drugs can help. Objective: To learn if it is safe to give people with certain cancers copanlisib together with rituximab and combination chemotherapy (DA-EPOCH-R). Eligibility: People ages 18 and older with relapsed and/or refractory highly aggressive B-cell lymphomas such as BL and certain types of DLBCL. Design: Participants will be screened with: Medical history Physical exam Bone marrow aspiration and biopsy. A needle will be put into their hipbone. Marrow will be removed. Imaging scans of the chest, abdomen, pelvis, and/or brain Tumor biopsy (if needed) Blood and urine tests Heart function tests Treatment will be given in 21-day cycles for up to 6 cycles. Participants will get copanlisib by intravenous (IV) infusion. They will also get a group of medicines called DA-EPOCH-R, as follows. They will get rituximab by IV infusion. Doxorubicin, etoposide, and vincristine will be mixed together in an IV bag and given by continuous IV infusion over 4 days. They will get cyclophosphamide by IV infusion. They will take prednisone by mouth. Participants will have frequent study visits. At these visits, they will repeat some screening tests. They may give tissue, saliva, and cheek swab samples. They will have at least one spinal tap. For this, a needle will be inserted into the spinal canal. Fluid will be removed. Participants will have a visit 30 days after treatment ends. They will have follow-up visits for at least 5 years.

Background: Burkitt Lymphoma (BL) is a highly aggressive B cell lymphoma that often involves the bone marrow and central nervous system (CNS) Frontline therapy cures 80-85% of adults with BL but patients with CNS involvement or those who relapse after frontline therapy are at high risk for treatment failure Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous group of aggressive B-cell lymphomas that are successfully cured by frontline therapy in 60-70% of cases A subset of DLBCL that have MYC gene rearrangement as well as those that have transformed from an underlying indolent lymphoma have a lower cure rate Dose-adjusted (DA)-EPOCH-R is an infusional chemotherapy platform often used as frontline therapy for these aggressive B-cell lymphomas and is an effective chemotherapy platform from which to rationally design novel therapies for patients with BL, high grade B-cell lymphomas- double hit/triple hit (HGBCL-DH/TH), DLBCL and MYC rearrangements, and other high-risk DLBCL The phosphoinositide 3-kinase (PI3K) pathway is an important signaling pathway for cellular responses to growth factors and a downstream event of B-cell receptor signaling. Copanlisib targets both PI3K-a and PI3K-d isoforms and is approved for relapsed FL, active as monotherapy in DLBCL, and highly effective in pre-clinical models of BL Copanlisib crosses the blood brain barrier suggesting it may prevent secondary CNS spread in highly aggressive B-cell lymphomas. Copanlisib is a rational targeted agent to be added to DA-EPOCH-R in patients with BL, HGBCL-DH/TH, and other high-risk B-cell lymphomas. Objective: To determine the Maximal tolerated dose (MTD) and Recommended Phase II dose (RP2D) of copanlisib in combination with DA-EPOCH-R in subjects with Burkitt lymphoma (BL) and high grade B-cell lymphomas- double hit/triple hit (HGBCL-DH/TH) relapsed after or refractory to chemo-immunotherapy Eligibility: Subjects must have a histologic diagnosis, confirmed by the Laboratory of Pathology, NCI with one of the following subtypes and prior therapy, as follows: Burkitt lymphoma, Burkitt-like lymphoma with 11q aberration, High-grade B-cell lymphoma, NOS, High-grade B-cell lymphoma, with MYC and BCL2 and/or BCL6 rearrangements - following at least 1 anthracycline-containing regimen OR DLBCL, NOS, Germinal center B-cell type (GCB) type, T-cell/histocyte-rich large B-cell lymphoma, following at least 1 anthracycline-containing regimen AND at least 2 prior regimens OR be primary refractory to frontline therapy Age >= 18 ECOG performance status 0-2 Adequate bone marrow and organ function Design: Phase 1, open-label, single center, non-randomized "3+3" dosing will be used to determine the RP2D and MTD of dose escalated copanlisib in combination with standard regimen DA-EPOCH-R Maximum 6 cycles (21-day cycles) of combination therapy Dose expansion at the RP2D or MTD to evaluate efficacy and further evaluate safety To explore all dose levels, including further evaluation in dose expansion cohort, the accrual ceiling will be set at 39

NOTE: Minor procedures requiring Twilight sedation, such as tissue biopsies, endoscopies or mediport placement require a 24-hour waiting period prior to treatment initiation. Women of childbearing potential (WOCBP) and men with female partners of childbearing potential must agree to use a highly effective method of contraception when sexually active (intrauterine device, surgical sterilization, contraceptive rod, abstinence) for the time period between signing of the informed consent form and for at least 1 month after the last dose of copanlisib. WOCBP and men with female partners of childbearing potential must agree to use an effective method of contraception (two of the following: diaphragm, cervical cap, contraceptive sponge, condom, hormonal) when sexually active for the time period between signing of the informed consent and for at least 12 months after the last dose of rituximab. Women of childbearing potential must have a serum pregnancy test performed a maximum of 7 days before start of treatment, and a negative result must be documented before start of treatment. NOTE: A woman is considered of childbearing potential, (i.e., fertile), following menarche and until becoming post-menopausal unless permanently sterile. 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 postmenopausal state in women not using hormonal contraception or hormonal replacement therapy. The investigator or a designated associate is requested to advise the subject 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, asectomized partner and sexual abstinence.

Requirement to continue on any of the medications that are excluded Breast-feeding subjects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with these agents, breastfeeding should be discontinued if the mother is treated on study.
