  6. Patients with previously diagnosed and teated indolent lymphoma
  7. Know CNS involvement of DLBCL
  8. Past or current malignancy, except for - cervical carcinoma stage 1B or less, Non-invasive basal cell and/or squamous cell carcinoma, malignant melenoma with a complete response of a duration of less than 10 years, other cancer diagnosis with a complete response of a duration of less than 5 years
  9. Chronic or ongoing active infectious disease including requiring systemic treatment such as, but not limited to, chronic renal infection, chronic chest infection with bronchiectasis, tuberculosis and active hepatitis C.
  10. Clinically significant cardiac disease including unstable angina, acute myocardial infarction with six months from visit 1, congestive heart failure (NYHA III-IV), and arrhythmia requiring therapy, with the exception of extra systoles or minor conduction abnormalities.
  11. Significant concurrent, uncontrolled medical condition including, but not limited to, renal, hepatic, gastrointestinal, endocrine, pulmonary, neurological, cerebral or psychiatric disease.
  12. History of significant cerebrovascular disease
  13. Known HIV positive

  15. Screening lab values: Platelets < 50 x 10/9/L (unless due to DLBCL involvement of the bone marrow).  Neutrophils < 1.0 x 10/9/L (unless due to DLBCL involvement of the bone marrow).  Creatinine > 2.0 times upper normal limit (unless normal creatinine clearance).  Total bilirubin > 1.5 times upper normal limit (unless due to liver involvement of DLBCL).  ALT > 2.5 times upper normal limit (unless due to liver involvement  of DLBCL).  Alk Phos > 2.5 times upper normal limit (unless due to liver involvement  of DLBCL). 
  16. Known or suspected hypersensitivity to components of investigational product
  17. Life expectancy less than 6 months
  18. Patients who have received tratment wiht any non-marketed drug substance or experimental therapy within 4 weeks prior to visit 2
  19. Currents participation in any other interventional clinical trial
  20. Patients known or suspected of not being able to comply with a trial protocol (e.g. due to alcoholism, drug dependency or psychological disorder)
  21. Breat feedinig women or women with a positive pregnacy test at visit 1
  22. Women of cheldbearing potential not willing to use adequate contraception during trial oand one year after last dose of ofatumumab.  Adequate contraception is defined as hormonal birth control or intrauterine device.  For patients in the USA the use of a double barrier method is also considered adequate.

R-GCVP

A Phase II multicentre trial of Gemcitabine, CVP,and Rituximab (R-GCVP) for the treatment of patients with newly diagnosed Diffuse Large B-Cell Lymphoma, considered unsuitable for R-CHOP chemotherapy

Orcharrd

This is a Phase II/III, parallel group, open label, active comparator, randomised (1:1), registration trial. Subjects must be refractory to, or have relapsed following, first-line treatment with rituximab in combination with an anthracycline containing regimen, and be eligible for ASCT. Subjects with the following disease responses will be deemed refractory: 1) progressive disease during first-line treatment, 2) stable disease after at least 3 cycles of first-line treatment, and 3) PR after at least 6 cycles of first-line treatment. For relapsed patients, or patients with PR, CD20 positive DLBCL must be re-confirmed during the interval between completion of first-line treatment and prior to trial entry. Subjects will be randomised to receive either rituximab or ofatumumab in combination with three cycles of salvage chemotherapy using DHAP-VIM-DHAP (DVD). A total of four doses of ofatumumab or rituximab will be dosed as follows: Day 1 and Day 8 of cycle 1, and Day 1 of cycle 2 and cycle 3. Disease assessments, including CT and PET scans, will be performed at screening. After the second cycle of salvage therapy a CT scan will be performed and subjects not achieving CR or PR will be considered treatment failures and will not receive any further protocol therapy. CT and PET scans will be performed after the third cycle of salvage therapy and, provided that there is continuing response, subjects will continue with treatment as per protocol. Recognised disease response criteria will be used (Cheson et al., 2007). According to local policy, during the second and/or third cycle of salvage therapy, stem cells will be mobilized with GCSF and harvested. Responding patients will receive high dose chemotherapy with BEAM followed by autologous stem cell transplantation. Success of engraftment will be assessed.
