This research study is evaluating the combination of two drugs, copanlisib and venetoclax, as a possible treatment for trelapsed/refractory diffuse large B-cell lymphoma (DLBCL)

The names of the study drugs involved in this study are:

  • Copanlisib
  • Venetoclax


This study is an open-label, multi-center, non-randomized phase I/II study of the combination treatment copanlisib + venetoclax in patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL).

Phase I clinical trials test the safety of investigational drugs, and also try to define the appropriate dose of the investigational drugs to use for further studies. Phase II clinical trials test the safety and effectiveness of investigational drugs to learn whether the drugs work in treating a specific disease."Investigational" means that the drugs are being studied.

Copanlisib is an IV medication that is approved by the U.S. Food and Drug Administration (FDA) for the treatment of adult patients with relapsed follicular lymphoma who have received at least two prior therapies. Venetoclax is an oral medication that is approved by the U.S. FDA for the treatment of adult patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) and certain patients with acute myeloid leukemia (AML). The FDA has not approved copablisib or venetoclax for the treatment of DLBCL or the combination of copanlisib and venetoclax as a treatment for any disease.

In the phase I portion of this study, the investigators are looking to determine the dose of venetoclax that is safe to give with copanlisib and to see what the side effects are of this combination.

In the phase II trial, the investigators will be determining how effective venetoclax and copanlisib are for the treatment of R/R DLBCL. Data from laboratory suggest that some subsets of DLBCL are enriched for mutations that make them sensitive to the combination of copanlisib plus venetoclax. This study will look at genetic changes in your cancer and determine if abnormalities in specific genes make these drugs more or less effective.

It is expected that about 48 people will take part in this research study.

Bayer, a pharmaceutical company, is supporting this research study by providing the study drug copanlisib and funding for this study. Abbvie, a pharmaceutical company, is supporting this research study by providing the study drug venetoclax and funding for this study.

Yes No Not Sure

Inclusion Criteria

A confirmed diagnosis of DLBCL according to the 2016 WHO classification. Patients with high-grade B-cell lymphoma with translocations of MYC and BCL-2 and/or BCL-6 are eligible
Relapsed after autologous stem cell transplantation or chimeric antigen receptor (CAR) T-cell therapy or not a candidate for these therapies
Willingness to undergo a pre-treatment biopsy. If considered unsafe to proceed with biopsy, archival tissue samples may be utilized after discussion with the PI. Archival samples performed within 90 days and without intervening therapy are also acceptable if they meet the criteria as specified in the laboratory manual
ECOG performance status < 2
Age ≥ 18 years
Patients must meet the following hematologic criteria at screening
Absolute neutrophil count ≥1000 cells/mm3 (0.5 x 109/L), with no white-blood cell growth factor use for at least 7 days prior to screening
Platelet count ≥75,000 cells/mm3 (75 x 109/L) or ≥50,000 cells/mm3 (50 x 109/L if documented disease involvement of the bone marrow), without platelet transfusion within 7 days of screening
Hemoglobin (Hb) ≥ 8 g/dL, without blood transfusion within 7 days of screening
Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 x ULN (≤ 5 x
ULN for patients with liver involvement by lymphoma)
Lipase ≤ 1.5 x ULN
Total bilirubin ≤ 1.5 x ULN (< 3 x ULN for patients with Gilbert's syndrome, patients with cholestasis due to compressive adenopathies of the hepatic hilum or documented liver involvement or with biliary obstruction due to lymphoma)
Adequate renal function defined by serum creatinine ≤1.5 x ULN or creatinine clearance (by Cockroft-Gault) ≥ 50 ml/min
Women of childbearing potential (WOCBP) and men must agree to use effective contraception when sexually active. This applies for the time period between signing of the informed consent form and 6 months for WOCBP and for men after the last administration of study treatment. 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 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, e.g. intrauterine device (IUD), intrauterine hormone-releasing system (IUS), bilateral tubal occlusion, vasectomized partner, use of two forms of birth control, and sexual abstinence. The use of condoms by male patients is required unless the female partner is permanently sterile
Ability to understand and the willingness to sign a written informed consent document
