Chemotherapy-free treatment effective for CLL/SLL

New trial shows a combination of ibrutinib and obinutuzumab is an alternative to ibrutinib plus chemo in first-line treatment of CLL/SLL

Text that says Results

The results of a clinical trial called iLLUMINATE have been published this month in the Lancet Oncology.

The study compared two treatments in people with chronic lymphocytic leukaemia (CLL) / small lymphocytic lymphoma (SLL) who had not been treated before. The two treatments were:

ibrutinib (a targeted drug) + obinutuzumab (a monoclonal antibody)

chlorambucil (a chemotherapy drug) + obinutuzumab.

Both treatments involved 6 cycles lasting 28 days each.

A total of 229 people took part in the study. By 30 months (2.5 years) after treatment, lymphoma had not progressed in 79% of people who were treated with ibrutinib + obinutuzumab lymphoma compared with 31% of people who were treated with ibrutinib + chlorambucil. In other words, the treatment response lasted longer for people treated with ibrutinib + obinutuzumab. However, they also experienced more side effects.

The researchers concluded that ibrutinib + obinutuzumab is an effective and safe chemotherapy-free treatment and provides an alternative option for patients with CLL/SLL who have not been treated before.
