Hundreds could benefit as treatment gains registration for new use
News release

For immediate release
Widened access to a leading-edge biotherapy has given hope to hundreds of New Zealanders diagnosed with chronic
lymphocytic leukaemia (CLL), a stubbornly incurable form of white blood cell cancer.
Internationally, CLL is the most common type of leukaemia to affect adults [i] accounting for approximately 25-30 per
cent of all leukaemias. [ii] More than 140 New Zealanders are diagnosed with CLL each year and approximately 35 will die
from the disease. [iii]
Peter Browett, consultant haematologist at Auckland City Hospital and Medical Director of the New Zealand based
Leukaemia and Blood Foundation, says the recent Medsafe registration of MabThera® (rituximab) in combination with
chemotherapy for patients with previously untreated CLL [iv] comes as good news as traditionally CLL has been a
difficult disease to treat.
“MabThera is the first biotherapeutic that, when added to chemotherapy, has been shown to extend disease free survival
and the quality of life of patients with previously untreated CLL. Many patients with CLL go through periods of
remission and relapse, severely impacting their quality and enjoyment of life.
“This new form of therapy will allow patients to enjoy a longer and more improved quality of life with less chance of
relapse or recurrence.”
Leanne Berkahn, also a consultant haematologist at Auckland City Hospital, says the addition of MabThera to chemotherapy
as a treatment for CLL is “an important and significant milestone in treatment and will provide benefit to both patients
and their families”.
Dr Berkahn says a large-scale clinical trial, has shown MabThera in combination with chemotherapy to be an effective
treatment for patients with previously untreated CLL. The results of the CLL8 trial, presented at the prestigious
American Society of Hematology (ASH) meeting in San Francisco in November last year, highlighted the effectiveness of
MabThera in extending the time patients with CLL lived without progression of their disease.
The CLL8 trial compared patients who had not previously received treatment, and who normally would receive chemotherapy
alone, with patients who received MabThera in combination with chemotherapy. [v]
The CLL8 trial showed that the addition of MabThera increased the number of patients entering complete remission and
significantly extended the length of time until disease progression when compared to chemotherapy alone.
Dr Berkahn says large international clinical trials in CLL have included more than 30 New Zealanders from Auckland,
Palmerston North, Wellington and Christchurch.
