Results from the pivotal GELA Study (Groupe d'Etude des Lymphomes de l'Adulte) have shown that three-year event free survival for patients treated with MabThera plus CHOP is 53%, compared to 35% for patients treated with CHOP alone2. Moreover, 62% of those patients receiving MabThera plus CHOP were still alive three years after treatment compared to 51% of the patients who were treated with chemotherapy alone. Importantly, MabThera did not increase the toxicity of therapy when compared to chemotherapy alone2.
"These results represent a real breakthrough for people with aggressive NHL. This combination therapy is the first treatment in 20 years to offer patients a great improvement in long term survival," commented principal GELA study investigator Professor Bertrand Coiffier, head of the Department of Hematology, Hospices Civiles de Lyon, France. "It confirms that MabThera plus CHOP is the gold standard treatment for this aggressive form of cancer. It is the only recent treatment in aggressive NHL proven to increase survival and potentially offer a cure without an increase in toxicity. People with aggressive NHL must be treated with this combination wherever possible."
MabThera works by 'seek and destroy' action, which unlike chemotherapy specifically targets tumour cells, therefore it does not cause the unpleasant side effects associated with traditional chemotherapy. Approximately 1.5 million people worldwide have NHL, 55% of them have the aggressive form of the disease, which if left untreated can be fatal within six months. The remaining 45% suffer from indolent NHL, where tumour cells divide slowly and patients may live for many years, however currently there is no cure. The causes of NHL remain unknown, however it is more common than leukaemia and worldwide is the third fastest growing form of cancer, after skin melanoma and lung cancer3.
MabThera was discovered by IDEC Pharmaceuticals Corporation and was jointly developed by IDEC, Genentech Inc, Roche and Zenyaku Kogyo Co. Ltd of Japan. In July 1998, Genentech granted Roche exclusive marketing rights for MabThera outside the USA. (marketed as Rituxan® in USA, Japan and Canada). MabThera is the Roche World-Wide Prescription Group's largest prescription product just four years after its first launch.

This phase III study was conducted by Groupe d'Etude des Lymphomes de l'Adulte (GELA), a large cancer co-operative group of more than 110 institutions in France, Belgium and Switzerland. The study analysed 399 previously untreated elderly patients (60 to 80 years old) with aggressive non-Hodgkin's lymphoma. Patients were randomised to receive standard CHOP chemotherapy or MabThera plus CHOP. June 2003
