Janssen gets positive CHMP opinion for IMBRUVICA (ibrutinib) to treat patients with previously untreated CLL

Recommendation based on RESONATE™-2 trial which showed IMBRUVICA significantly improved progression-free survival and prolonged overall survival versus chlorambucil

Janssen-Cilag International NV today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a Positive Opinion, recommending broadening the existing marketing authorisation for ibrutinib as a single agent for the treatment of adult patients with previously untreated chronic lymphocytic leukaemia (CLL).

Ibrutinib is approved for the treatment of adult patients with relapsed or refractory mantle cell lymphoma (MCL), or adult patients with chronic lymphocytic leukaemia (CLL) who have received at least one prior therapy, or in first line in the presence of 17p deletion or TP53 mutation (genetic mutations typically associated with poor treatment outcomes) in patients unsuitable for chemo-immunotherapy and in adult patients with Waldenström’s macroglobulinemia (WM) who have received at least one prior therapy, or in first line treatment for patients unsuitable for chemo-immunotherapy.

The Positive Opinion of the CHMP was based on data from the Phase 3, randomised, open-label RESONATE™-2 (PCYC-1115) clinical trial, as recently published in The New England Journal of Medicine (NEJM). Findings showed ibrutinib provided a significant improvement in all efficacy endpoints versus chlorambucil in patients aged 65 or older with newly diagnosed CLL. The progression-free survival (PFS) rate at 18 months was 90 percent for ibrutinib versus 52 percent for chlorambucil. Ibrutinib also significantly prolonged overall survival (OS) (HR=0.16 percent CI, 0.05, 0.56; P=0.001), with a 24-month survival rate of 98 percent, compared to 85 percent for patients in the chlorambucil arm. The safety of ibrutinib in the treatment-naïve CLL patient population was consistent with previously reported studies.2 The most common adverse reactions (ARs) (≥20 percent) of any Grade in the RESONATE-2 trial for ibrutinib were diarrhoea (42 percent), fatigue (30 percent), cough (22 percent) and nausea (22 percent).

CLL is a chronic disease, and the prevalence rate in Europe among men and women is approximately 5.87 and 4.01 cases per 100,000 persons per year, respectively. Median overall survival ranges between 18 months and more than 10 years according to the stage of disease.

“Janssen is proud to be leading the charge with our ongoing efforts to transform the treatment experience for patients with difficult to treat blood cancers, such as CLL,” said Jane Griffiths, Company Group Chairman, Janssen Europe, Middle East and Africa. “Ibrutinib continues to demonstrate impressive clinical results, and the data on which this recommendation is based once again highlight its potential to deliver improved patient outcomes for suitable patients.”

This regulatory milestone follows the decision by the U.S. Food and Drug Administration on 04 March 2016, to approve the expanded use of ibrutinib capsules for treatment-naïve patients with CLL.
