Sustained Benefit in Patients with Relapsed/Refractory Mantle Cell Lymphoma Demonstrated by 3.5 Year Follow-up Data of Imbruvica®▼(ibrutinib)
Today, Janssen-Cilag International NV (“Janssen”) announced results of a pooled analysis of relapsed/refractory (r/r) mantle cell lymphoma (MCL) patients treated with Imbruvica® (ibrutinib). The extended follow-up data demonstrated that patients treated with ibrutinib earlier (at first relapse) experienced the best clinical outcomes, both in terms of efficacy and tolerability. These data (abstract #151) were presented in an oral presentation at the 59th Annual American Society of Hematology (ASH) Meeting and Exposition in Atlanta, GA.1,2 Ibrutinib, a first-in-class Bruton’s tyrosine kinase (BTK) inhibitor, is jointly developed and commercialised by Janssen Biotech, Inc. and Pharmacyclics LLC, an AbbVie company.
“Data from this large clinical trial data set with extended follow-up support the early use of ibrutinib in patients with relapsed or refractory mantle cell lymphoma,” said Simon Rule, M.D., Professor in Haematology at Plymouth University Medical School, United Kingdom, and lead investigator and presenter of the pooled analysis.* “Long-term follow-up for ibrutinib demonstrates, that in addition to efficacy, new onset adverse events decrease over time and are generally less common when patients are treated earlier.”
MCL is one of several subtypes of B-cell non-Hodgkin lymphoma (NHL) and represents about five to seven percent of malignant lymphoma in Western Europe.3 MCL usually begins with lymph node enlargement and can potentially spread to other tissues such as the bone marrow and liver.4 Median overall survival for MCL patients is three to four years.5
Abstract #151: Median 3.5-year Follow-Up of Ibrutinib Treatment in
Patients with Relapsed/Refractory Mantle Cell Lymphoma: A Pooled
Oral presentation: Saturday, December 9, 2017, 12:00 PM ET
The pooled analysis includes results from Phase 2 and 3 studies (SPARK, PCYC-1104, and RAY; n=370), and additional follow-up of 87 patients across these studies who enrolled in the long-term open-label extension study, CAN3001. Eighty-three patients were treated with ibrutinib for three or more years, and 40 patients were treated with ibrutinib for four or more years.1,2 With 3.5 years (41 months) of follow-up, the median progression free survival (PFS) overall was 13 months, and 33.6 (range, 19.4-42.1) months in patients with one prior line of therapy.1,2 The median PFS in patients achieving complete response (CR) was 46.2 (range, 42.1-not estimable [NE]) months and the duration of response in these patients was 55.7 (range, 55.7-NE) months.1 Patients with favourable baseline disease characteristics were more likely to remain on ibrutinib for more than three years.2 Overall, 53 percent (95 percent confidence interval, 0.47-0.58), 45 percent (0.39-0.50), and 37 percent (0.25-0.49) of patients were alive at two, three, and five years, respectively,2 and the median overall survival (OS) was 26.7 months.1,2
Grade 3 or higher treatment-emergent adverse events (TEAEs) occurred in 79.7 percent of patients, with the new onset events decreasing after the first year. New onset grade 3/4 TEAEs were generally less common in patients who were treated earlier with ibrutinib.1,2 In these studies, that permitted enrolment of patients with multiple cardiac risk factors, and among patients experiencing grade 3/4 atrial fibrillation, no patients discontinued treatment and <1 percent had a dose reduction.1
“We are proud that these results demonstrated the long-term safety and efficacy of ibrutinib after one prior line of therapy in patients with previously treated MCL,” said Dr Catherine Taylor, Haematology Therapeutic Area Lead, Janssen Europe, Middle East and Africa. “As we build on the clinical evidence for ibrutinib, we continue to see sustained benefits in treating B-cell malignancies such as MCL, supporting positive outcomes for such a large patient population in the long-term.”
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.6 By blocking this BTK protein, ibrutinib helps kill and reduce the number of cancer cells, thereby delaying progression of the cancer.7
Ibrutinib is currently approved in Europe for the following uses:8
- As a single agent for the treatment of adult patients with previously untreated chronic lymphocytic leukaemia (CLL), adult patients with relapsed or refractory mantle cell lymphoma (MCL), or adult patients with Waldenström’s Macroglobulinaemia (WM) who have received at least one prior therapy or in first-line treatment for patients unsuitable for chemo-immunotherapy.
- As a single agent or in combination with bendamustine and rituximab (BR) for the treatment of adult patients with CLL who have received at least one prior therapy.
Please see the ibrutinib Summary of Product Characteristics for further information.8
Mantle Cell Lymphoma (MCL) is considered a rare disease, characterised by high unmet need and small patient populations impacting fewer than one in 200,000 people in Europe and with a median age at diagnosis of 65.4,9 MCL predominantly affects more men than women and accounts for five to 10 percent of all non-Hodgkin’s lymphomas.4,10 MCL typically involves the lymph nodes, but can spread to other tissues, such as the bone marrow, liver, spleen and gastrointestinal tract.4
