Study of Mini-Chop Plus Ofatumumab To Treat Cd 20+ Diffuse Large B-Cell Lymphoma In Patients Aged Over 80 Years

• Status: Completed
• Trial end date: 2014-04-01
• Target enrollment: 0
• Participant gender: All

Summary

This study is a multicentric, phase II, open-label, non-randomized trial evaluating the efficacy of O-miniCHOP in patients aged over 80 years with non previously treated CD20+ diffuse large B-cell lymphoma (age-adjusted IPI=0 to3), stage I, II, III or IV with a performance status ECOG from 0 to 4.

The anticipated study dates (start / end) are: 2010 - 2013. The study will evaluate a cohort of 120 patients (approximately 95 in France, 15 in Belgium, 5 in Switzerland and 5 in Portugal).

Patients will be recruited over 30 months and followed at least one year after the last patient has been included.

The duration of the treatment period is approximately 20 weeks.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

• Lead Sponsor: The Lymphoma Academic Research Organisation

Criteria

Inclusion Criteria:

Patient with histologically proven CD20+ diffuse large B-cell lymphoma (DLBCL) (WHO classification 2008) including clinical subtypes (primitive mediastinal, intravascular, etc.) May also be included : de Novo Transformed DLBCL from low grade lymphoma (Follicular, other...) and DLBCL associated with some small cell infiltration in bone marrow

• Or CD20+ B-cell lymphoma, with intermediate features between DLBCL and Burkitt or with intermediate features between DLBCL and classical Hodgkin lymphoma

• Or CD20+ Follicular lymphoma grade 3B

• Or CD20+ Aggressive B-cell lymphoma unclassifiable Aged over 80 years. Ann Arbor stage I, II, III or IV. All aaIPI Patient non previously treated. All ECOG performance status With a minimum life expectancy of 3 months. Negative HIV, HBV and HCV serologies test < 4 weeks (except after vaccination). Patient able to give his consent and having previously signed a written informed consent.

Patient affiliated to social security system, if applicable

Exclusion Criteria:

Any other histological type of lymphoma, Burkitt included. Any history of treated or non-treated small-B cell lymphoma. Central nervous system or meningeal involvement by lymphoma. Contra-indication to any drug contained in the chemotherapy regimens. Any serious active disease (according to the investigator's decision). Poor renal function (creatinin level>150µmol/l), poor hepatic function (total bilirubin level>30mmol/l, transaminases>2.5 maximum normal level) unless these abnormalities are related to the lymphoma.

Poor bone marrow reserve as defined by neutrophils <1.5 G/l or platelets <100 G/l, unless related to bone marrow infiltration.

Any history of cancer during the last 5 years with the exception of non-melanoma skin tumors or stage 0 (in situ) cervical carcinoma. Patients previously diagnosed with prostate cancer are eligible if (1) their disease was T1-T2a, N0, M0, with a Gleason score <7, and a prostate specific antigen (PSA) <10 ng/mL prior to initial therapy, (2) they had definitive curative therapy (ie, prostatectomy or radiotherapy) >2 years before Day 1 of Cycle 1, and (3) at a minimum 2 years following therapy they had no clinical evidence of prostate cancer, and their PSA was undetectable if they underwent prostatectomy or <1 ng/mL if they did not undergo prostatectomy.

Treatment with any investigational drug within 30 days before planned first cycle of chemotherapy and during the study.

Prior treatment with anti-CD20 monoclonal antibody or alemtuzumab within 3 months prior to start of therapy Adult patient under tutelage.
