About

This is a prospective, multicenter, non-randomized, open-label, phase II study to describe the efficacy of R-CHOP plus copanlisib including a safety run-in phase in order to detect early and common unexpected toxicities caused by the addition of copanlisib to the standard immuno-chemotherapy R-CHOP in patients with diffuse large B-cell lymphoma (DLBCL)

Full description

Patients diagnosed with DLBCL can be cured with a combined approach of CHOP chemotherapy and the anti-CD20 antibody rituximab in roughly 65% of cases. About one third of patients with DLBCL relapse or show primary progressive disease after modern first-line therapy. The outcome of these patients is poor in particular if first-line therapy contained rituximab. Novel therapeutic approaches are urgently warranted. Thus, it is the goal to further improve progression-free Survival (PFS) and overall Survival (OS) by combining R-CHOP with copanlisib. Copanlisib is a small molecule pan-class 1 PI3K inhibitor and approved by US FDA for the treatment of adult patients with relapsed follicular lymphoma who have received at least two prior systemic therapies.

Inclusion criteria

Histologically confirmed

  • DLBCL (NOS) or
  • High-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements or
  • High-grade B-cell lymphoma (NOS)
  • Follicular lymphoma Grade 3B (primary diagnosis without history of indolent lymphoma) with a diagnostic biopsy performed within 3 months before study entry and with material available for central review and complimentary scientific analyses
  • 18-80 years of age
  • International Prognostic Index (IPI) 2-5
  • Eastern Cooperative Oncology Group Performance status (ECOG) 0-2
  • Life expectancy of at least 3 months

Women of childbearing potential 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 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 (failure rate of less than 1%), e.g. intrauterine device, intrauterine hormone-releasing system, bilateral tubal occlusion, vasectomized partner and sexual abstinence. The use of condoms by male patients is required unless the female partner is permanently sterile.

Adequate baseline laboratory values collected no more than 7 days before starting study treatment:

  • Total bilirubin ≤ 1.5 x ULN (< 3 x ULN for patients with Gilbert syndrome, patients with cholestasis due to compressive adenopathies of the hepatic hilum or documented liver involvement or with biliary obstruction due to lymphoma)
  • 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
  • Glomerular filtration rate (GFR) ≥ 40 mL/min/1.73 m2 according to the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula. If not on target, this evaluation may be repeated once after at least 24 hours either according to the CKD-EPI formula or by 24-hour sampling. If the later result is within acceptable range, it may be used to fulfill the inclusion criteria instead.
  • INR and PTT ≤ 1.5 x ULN
  • Platelet count ≥ 75,000 /mm3.
  • Hemoglobin (Hb) ≥ 8 g/dL
  • Absolute neutrophil count (ANC) ≥ 1,500/mm3
  • Left ventricular ejection fraction ≥ 50%
  • No prior lymphoma therapy
  • Ability to understand and willingness to sign written informed consent. Signed informed consent must be obtained before any study specific procedure.

Exclusion criteria

Patients who meet any of the following criteria at the time of screening will be excluded.

  • Previous assignment to treatment during this study. Patients permanently withdrawn from study participation will not be allowed to re-enter the study.
  • Previous (within 28 days or less than 5 half-lives of the drug before start of study treatment) or concomitant participation in another clinical study with investigational medicinal product(s).

Close affiliation with the investigational site; e.g. a close relative of the investigator, dependent persons (e.g. employee or student of the investigational site).

Excluded medical conditions:

  • Type I or II diabetes mellitus with HbA1c > 8.5% at screening or fasting plasma glucose > 160 mg/dL at screening

  • Known lymphoma involvement of the central nervous system
  • Human immunodeficiency virus (HIV) infection
  • Hepatitis B (HBV) and C (HCV) infection. Patients with serologic markers of HBV immunization due to vaccination (HBsAg negative, Anti-HBc negative and Anti-HBs positive) will be eligible
  • CMV-PCR positive at baseline

Copanlisib and R-CHOP chemotherapy
Experimental group
Description:
All patients will receive 6 cycles of R-CHOP immunochemotherapy every two weeks with the following doses per cycle: rituximab 375 mg/m², cyclophosphamide 750 mg/m², doxorubicin 50 mg/ m², vincristine 1.4 mg/m² (dose capped at 2 mg or 1 mg for individuals above 60 years of age), prednisolone 500 mg. In addition, copanlisib at a dose of 60 mg will be administered on days 1 and 8 of each 21-day cycle of R-CHOP in the first 6 patients. If dose limiting toxicity (DLT) occurs in no more than one out of these 6 patients during cycle 1, additional 6 patients at 60 mg will be enrolled and treated for at least 1 cycle before opening the phase II portion of the study. If a DLT is observed in 2 or more of the first 6 patients during cycle 1 the dose of copanlisib will be reduced to 45 mg on days 1 and 8 for the next 6 patients. The data of the safety run-in analysis (first 12 patients) will be presented to the Data Safety Monitoring Board and the recommended phase 2 dose will be determined.
