About

Patients with CD30 positive DLBCL, primary refractory or in first relapse after R-CHOP or R-CHOP-like therapy will receive brentuximab vedotin in combination with R-DHAP, followed in responsive patients by high dose chemotherapy and ASCT.

Full description

Patients with primary refractory or relapse diffuse large B cell lymphoma (DLBCL) after R-CHOP have a dismal prognosis. Only 25% long term survivors are observed after salvage with high-dose chemotherapy followed by autologous stem cell transplantation (ASCT). CD30 expression is observed in 30% of refractory/relapse DLBCL.

Monotherapy with brentuximab vedotin is effective in relapse CD30 positive DLBCL. The addition of brentuximab vedotin to R-DHAP might improve the prognosis of these patients.

Treatment will consist of 3 cycles of brentuximab-vedotin in combination with R-DHAP. During the phase I part the recommended dose level for this combination will be established. Cycles will be given every 3 weeks.

Responsive patients will be treated with BEAM followed by ASCT. Total treatment duration is approximately 16 weeks.

Subsequently patients will be followed until 5 years after registration.

Inclusion criteria

CD30 positive DLBCL, i.e. more than 1% of DLBCL cells CD30 positive(central pathology review results not required to enter patient into the study), according to the WHO classification 2008:
- CD30 positive DLBCL, including EBV positive DLBCL
- CD30 positive primary mediastinal B-cell lymphoma
Primary refractory to or in first relapse after first line therapy with R-CHOP or R-CHOP-like therapy
- Relapse is defined as biopsy confirmed CD30 positive DLBCL after a complete response. The relapse must be histologically confirmed. In case a surgical biopsy is not possible, at least confirmation by FNA biopsy is required
- Refractory disease is defined as:
  1. progressive disease during first line therapy, In this case biopsy confirmation of CD30 positive DLBCL is preferred but not required
  2. stable disease after at least 3 cycles of first line therapy, In this case biopsy confirmation of CD30 positive DLBCL is preferred but not required
  3. PR after at least 6 cycles of first line therapy, or in the case of stage I-II disease after at least 3 cycles of therapy and definitive involved field radiotherapy. In this case refractory disease must be histologically confirmed
Age ≥ 18 years (upper age limit for ASCT at the discretion of the participating center)
Measurable disease: on CT scan at least 1 lesion/node with a long axis of > 1.5 cm and at least one positive lesion on 18F-FDG PET scan
WHO performance status 0-2, status 3 only if disease related (see appendix C)
Adequate hepatic function: total bilirubin ≤ 1.5 times ULN (unless due to lymphoma involvement of the liver or a known history of Gilbert's syndrome as defined by > 80% unconjugated bilirubin) and ALAT/ASAT ≤ 3 times ULN (unless due to lymphoma involvement of the liver; in that case ALAT/ASAT may be elevated up to 5 times ULN)
Adequate renal function: GFR > 60 ml/min as estimated by the Cockroft&Gault formula at rehydration: CrCL = (140-age [in years] x weight [kg] (x 0.85 for females) / (0.815 x serum creatinine [μmol/L])
Adequate bone marrow function: Absolute neutrophil count (ANC) ≥ 1.5x109/L and platelet count ≥ 100 x 109/L, unless caused by diffuse bone marrow infiltration by the NHL
Hemoglobin must be ≥ 8 g/dL (5.0 mmol/L), transfusion is allowed
Eligible for high-dose chemotherapy and ASCT
Resolution of relevant toxicities from first-line therapy
Life expectancy of > 3 months with treatment
Negative pregnancy test at study entry, if applicable
Female patient is either post-menopausal for at least 1 year before screening visit or surgically sterile or if of childbearing potential, agrees to practice 2 effective methods of contraception, at the same time, or agrees to completely abstain from heterosexual intercourse, from the time of signing the informed consent through 12 months after the last dose of study drug
Male patients, even if surgically sterilized, (i.e. status post vasectomy) agree to practice effective barrier contraception, or agrees to completely abstain from heterosexual intercourse, during the entire study period and through 12 months after the last dose of study drug
Written informed consent
Patient is capable of giving informed consent

Exclusion criteria

Peripheral sensory or motor neuropathy grade ≥ 2
Known cerebral or meningeal disease (NHL or any other etiology), including signs and symptoms of progressive multifocal leukoencephalopathy (PML)
Symptomatic neurological disease compromising normal activities of daily living or requiring medications

Treatment with myelosuppressive chemotherapy or biological therapy ≤ 4 weeks before study entry
Female patients who are breast feeding
History of another malignancy less than 3 years before study inclusion, or previously diagnosed with another malignancy and have evidence of residual disease, with the exception of non-melanoma skin cancer, completely resected melanoma TNMpT1 and carcinoma in situ of the uterine cervix
Known hypersensitivity to recombinant proteins, murine proteins, or to any excipient contained in the drug formulation of brentuximab vedotin
Active hepatitis B or C infection as defined by positive serology and transaminitis. Non-active hepatitis B carriers or anti-HBc positive patients may be included if protected with lamuvidine or entecavir (see 9.4)
HIV positivity
Radiation therapy within 8 weeks prior to start of protocol treatment. Emergency radiation therapy is allowed, as long as measurable disease (at non-irradiated sites) persists
Patients with a serious psychiatric disorder that could, in the investigator's opinion, potentially interfere with the completion of treatment according to protocol
