Today, Boehringer Ingelheim has announced the submission of a Marketing
Authorisation Application to the European Medicines Agency (EMA) for
approval of afatinib, the first irreversible ErbB Family Blocker, as a
treatment for patients with EGFR (ErbB1) mutation positive non-small
cell lung cancer (NSCLC). Afatinib has demonstrated unprecedented
efficacy versus chemotherapy in the Phase III LUX-Lung 3 registration
trial, which provides pivotal support for this submission.
NSCLC comprises over 85% of the 391,000 new cases of lung cancer
diagnosed annually in Europe, with adenocarcinoma being the most common
type of NSCLC. Approximately 20-30% of all lung
adenocarcinomas harbour EGFR mutations. Because of its
poor prognosis, approximately 340,000 deaths each year in Europe are
attributed to lung cancer, making it the most common cause of cancer
death.
"With so many people being diagnosed with, and dying from lung cancer,
there is still a clear need for effective and tolerable therapies.
Boehringer Ingelheim is committed to helping patients have access to
afatinib as soon as possible," said Prof. Klaus Dugi, Corporate Senior
Vice President Medicine, Boehringer Ingelheim. "The positive clinical
evidence for afatinib, coupled with its novel mode of action, could
make this an outstanding treatment option, providing much needed
benefits for lung cancer patients."
The submission is based on the comprehensive LUX-Lung clinical trial
programme. Data from the pivotal LUX-Lung 3 trial, comparing afatinib
to the best-in-class chemotherapy (pemetrexed and cisplatin) for
nonsquamous NSCLC, demonstrated superiority in patients with stage IIIb
or IV adenocarcinoma of the lung harbouring an EGFR mutation. Patients
taking afatinib as a first-line treatment lived for almost one year
without their tumour growing (progression-free survival (PFS) of 11.1
months) versus just over half a year (PFS of 6.9 months) for those on
chemotherapy (pemetrexed / cisplatin). Furthermore, NSCLC
patients with tumours harbouring the two most common EGFR mutations
(del19 and L858R, accounting for 90% of all tumours with EGFR mutations)
taking afatinib lived for well over a year without disease progression
(PFS of 13.6 months) versus just over half a year (PFS of 6.9 months)
for those in the comparator arm.
The delay in disease progression for afatinib-treated patients was
associated with an improvement of life-restricting lung cancer symptoms.
More patients taking afatinib experienced an improvement in dyspnoea
(shortness of breath), cough, and chest pain. Afatinib also
significantly delayed the deterioration of these symptoms compared to
chemotherapy.
In addition, a standard questionnaire assessing the quality of life of
lung cancer patients revealed that afatinib treatment translated into a
better quality of life (e.g. at work and during household activities).
Additional data from the trial, including symptom improvement and
health-related quality of life results, will be presented at the ESMO
2012 Congress (European Society for Medical Oncology) in Vienna,
Austria, 28 September - 2 October 2012:
While the LUX-Lung 3 trial demonstrated the superiority of afatinib in
delaying disease progression versus best-in-class chemotherapy
(pemetrexed and cisplatin) for nonsquamous NSCLC, Boehringer Ingelheim
is also exploring the broader potential of afatinib. The company has
initiated two head-to-head trials (LUX-Lung 7 and 8) directly comparing
afatinib to the currently available tyrosine kinase inhibitors (TKIs),
gefitinib and erlotinib, respectively. Both trials are actively
recruiting patients.
