Dr. Mehdi Shahidi, Medical Head, Solid Tumour Oncology, Boehringer Ingelheim commented: "Whilst there have been some recent and significant advances in the treatment of squamous cell carcinoma of the lung, the intravenous administration and frequent visits to the hospital can be a challenge for patients often debilitated by this disease.
"In this context and supported by robust evidence from a Global head-to-head Phase III study, we are pleased to offer an effective oral treatment option for patients suffering from this type of lung cancer to the European market."
SqCC of the lung is associated with a poor prognosis, limited survival and symptoms like cough and dyspnoea. The median overall survival (OS) after diagnosis of advanced SqCC is around one year.
The marketing authorisation in Europe is valid for 28 countries within the EU. The EU regulatory submission was based on results of the head-to-head LUX-Lung 8 trial in patients with SqCC of the lung whose tumours progressed on or after first-line chemotherapy. Afatinib, compared to erlotinib, demonstrated:
Significant delay in progression of lung cancer (PFS, progression-free survival, primary endpoint), reducing the risk of cancer progression by 19%
Significant improvement in overall survival (OS, key secondary endpoint), reducing the risk of death by 19%
Significantly improved disease control rate (51% vs 40%; P=0.002)
An improvement in quality of life and control of cancer symptoms
The rate of severe adverse events was similar between the two treatment arms with differences observed in the incidence of certain side effects: a higher incidence of severe diarrhoea and stomatitis (mouth sores) was observed with afatinib compared to erlotinib (grade 3 diarrhoea: 10% vs 2%; grade 3 stomatitis: 4% vs 0%), while a higher incidence of severe rash/acne was reported with erlotinib compared to afatinib (grade 3 rash/acne: 10% vs 6%).
LUX-Lung 8 (NCT01523587) is part of the afatinib LUX-Lung programme – the largest collection of clinical trials of any EGFR tyrosine kinase inhibitor (TKI), with over 3,760 patients across eight studies conducted across the world. The comprehensive LUX-Lung programme includes two pivotal studies in the first-line setting for EGFR mutation-positive patients, LUX-Lung 3 and 6 which compared afatinib to chemotherapy regimens. In addition, the programme included two head-to-head studies (LUX-Lung 7 and 8) of afatinib versus first-generation EGFR TKIs.
The LUX-Lung programme has involved over 680 sites in 40 countries, reflecting the strong partnership between Boehringer Ingelheim and the lung cancer specialist community.
Afatinib is already approved in over 60 countries for the first-line treatment of EGFR mutation-positive NSCLC, and recent results from the LUX-Lung 7 trial positively underscore the benefits of afatinib versus gefitinib, another first-generation EGFR targeting agent in this indication.
Results of this global Phase IIb head-to-head trial demonstrated afatinib was superior in reducing the risk of lung cancer progression and the risk of treatment failure both by 27% compared to gefitinib.
Afatinib is approved in the EU under the brand name GIOTRIF for the first-line treatment of TKI naïve adult patients with advanced EGFR mutation-positive NSCLC. In April 2016 afatinib was approved by the European regulatory authority as a second-line treatment for SqCC of the lung.
