Janssen’s IMBRUVICA® (ibrutinib) Receives Positive CHMP Opinion for Expanded Use in Previously Untreated Chronic Lymphocytic Leukaemia Patients
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.1
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) .2 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.2 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.2 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).2
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.3
“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.
Ibrutinib is a first-in-class Bruton's tyrosine kinase (BTK) inhibitor, which works by forming a strong covalent bond with BTK to block the transmission of cell survival signals within the malignant B cells.4 By blocking this BTK protein, ibrutinib helps kill and reduce the number of cancer cells. It also slows down the progression of the cancer.1
Ibrutinib is currently approved in Europe for the treatment of adult patients with relapsed or refractory mantle cell lymphoma (MCL); adult patients with chronic lymphocytic leukaemia (CLL) who have received at least one prior therapy, or in first line patients with CLL in the presence of 17p deletion or TP53 mutation 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.5 Regulatory approval for additional uses has not yet been granted. Investigational uses for ibrutinib, alone and in combination with other treatments, are underway in several blood cancers.
Ibrutinib is co-developed by Cilag GmbH International, a member of the Janssen Pharmaceutical Companies, and Pharmacyclics LLC, an AbbVie company. Janssen affiliates market ibrutinib in EMEA (Europe, Middle East and Africa) as well as the rest of the world, except in the United States, where Janssen Biotech, Inc. and Pharmacyclics co-market it. Janssen and Pharmacyclics are continuing an extensive clinical development programme for ibrutinib, including Phase 3 study commitments in multiple patient populations – please see the ibrutinib summary of product characteristics for further information.
Findings of the RESONATE™-2 (PCYC-1115) trial showed ibrutinib provided a significant improvement in progression-free survival and other key clinical 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.2 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.2
The safety of ibrutinib in the previously untreated CLL patient population was consistent with previously reported studies.2,5 The adverse reactions (AR) reported in the RESONATE-2 trial reflect exposure to ibrutinib with a median duration of 17.4 months versus a median exposure to chlorambucil of 7.1 months: nearly 2.5 times longer exposure for ibrutinib.2 The most common non-haematological ARs of Grade ≥3 were pneumonia, hypertension and diarrhoea (all 4 percent).2
In most patients, CLL is generally a slow-growing blood cancer of the white blood cells called B-lymphocytes.6 The median age at diagnosis is 72 years,7 and incidence rates among men and women in Europe are approximately 5.87 and 4.01 cases per 100,000 persons per year, respectively.8 CLL is a chronic disease; median overall survival ranges between 18 months and more than 10 years according to the stage of disease.3 The disease eventually progresses in the majority of patients, and patients are faced with fewer treatment options each time. Patients are often prescribed multiple lines of therapy as they relapse or become resistant to treatments.
