About

This study evaluates bendamustine in patients aged over 60 years with classical Hodgkin Lymphoma treated by prednisone, vinblastine and doxorubicin. 90 patients will be enrolled in this study.

Full description

The usual treatment for Hodgkin lymphoma is chemotherapy Adriamycin (also known as doxorubicin) + Bleomycin + Vinblastine + Dacarbazine (ABVD). Studies have shown that patients aged over 60 years have a lower tolerance and efficiency during this treatment than younger patients. There are particular pulmonary toxicities with bleomycin included in the ABVD treatment.

Alternative treatment strategies have been proposed removing bleomycin in the Prednisone + Vinblastine + Adriamycin/Doxorubicin +Gemcitabine (PVAG) protocol evaluated in more than 60 patients. Compared to ABVD treatment, PVAG treatment presented a more favorable toxicity profile. The quality of response between the two treatments is substantially equal.

Bendamustine was evaluated in four studies in patients with Hodgkin lymphoma in relapse and showed higher efficacy than gemcitabine with an acceptable toxicity profile.

In this study, the Sponsor and the coordinating investigator propose to replace dacarbazine in the standard ABVD protocol by bendamustine and to stop using bleomycin.

The main objective of this study is to evaluate the safety and efficacy of bendamustine in patients treated with prednisone, vinblastine and doxorubicin. This is the PVAB treatment with which LYSARC and the coordinating investigator expect better tolerability and quality response.

Contra-indication to any drug contained in the chemotherapy regimens
Any serious active disease (according to the investigator's decision)
Poor hepatic function (total bilirubin level > 30 μmol/L or transaminases > 2.5 maximum normal level) unless these abnormalities are related to the lymphoma

2. they had definitive curative therapy (i.e. prostatectomy or radiotherapy) ≥ 2 years before Day 1 of Cycle 1,
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
Severe metabolic disease interfering with normal application of protocol treatment as uncontrolled diabetes mellitus leading to impossibility to perform PET scan
