New Boehringer Ingelheim Data To Be Presented On Health-Related Quality Of Life With Afatinib In Patients With EGFR Mutation-Positive Advanced NSCLC
Boehringer Ingelheim has announced new patient-reported health-related outcomes for its investigational oncology compound afatinib,* including lung cancer-related symptoms and quality of life (QoL). These data are secondary endpoints of LUX-Lung 3, a Phase III trial of afatinib (n=230) compared to chemotherapy (pemetrexed/cisplatin) (n=115) in patients with epidermal growth factor receptor (EGFR) mutation-positive advanced non-small cell lung cancer (NSCLC). The poster was presented at the ESMO 2012 Congress (European Society for Medical Oncology) on Sunday, September 30 at 6:45 – 8:15 a.m. ET.
According to the abstract, three lung cancer symptoms – cough, dyspnea (shortness of breath), and pain – were analyzed using the European Organization for Research and Treatment of Cancer (EORTC) quality of life questionnaire for lung cancer (QLQ-LC13). Results showed that a higher proportion of afatinib-treated patients had 10 point or more improvements in cough (67% vs. 60%; p=0.2444), dyspnea (64% vs. 50%; p=0.0103) and pain (59% vs. 48%; p=0.0513) compared with those treated with chemotherapy. Patients treated with afatinib also reported a delay in the worsening (time to deterioration) of their lung cancer-related symptoms – cough (HR=0.60; p=0.0072) and dyspnea (HR=0.68; p=0.0145) – compared with those treated with chemotherapy. The time to deterioration of pain was not significant between the treatment arms (HR=0.82; p=0.1913). Mean symptom scores over time significantly favored afatinib over chemotherapy for cough and dyspnea.[i]
Health-related QoL was measured using the EORTC QLQ-C30 questionnaire, which evaluated global health status/QoL (overall well-being) in addition to physical, cognitive, role, social and emotional functioning.[ii] Of these six measures, patients treated with afatinib experienced improvements in their global health-related quality of life and physical, cognitive and role functioning compared to chemotherapy (p<0.05).1
Consistent with the safety profiles of afatinib and cisplatin/pemetrexed, afatinib-treated patients reported worse scores for diarrhea, sore mouth and dysphagia; patients treated with cisplatin/pemetrexed reported worse scores for fatigue, nausea and vomiting.1
“Evaluating patient-reported outcomes in lung cancer, such as health-related quality of life, can help us understand a treatment’s impact beyond just following the size of the tumor,” said Lecia V. Sequist, MD, MPH, medical oncologist at Massachusetts General Hospital Cancer Center, assistant professor of medicine at Harvard Medical School, and one of the Principal Investigators for the LUX-Lung 3 trial.
“These health-related quality of life data, in addition to previously reported efficacy and safety data, provide important insight into the potential of afatinib for patients with EGFR mutation-positive advanced non-small cell lung cancer,” said Berthold Greifenberg, MD, vice president, Clinical Development and Medical Affairs, Oncology, Boehringer Ingelheim Pharmaceuticals, Inc.
In addition to these data, results from 12 additional abstracts of Boehringer Ingelheim’s investigational oncology compounds were selected for presentation at the ESMO 2012 Congress.

Methodology for Measuring Patient-Reported Outcomes
Patient-reported outcomes were measured using European Organization for Research and Treatment of Cancer (EORTC) questionnaires (QLQ-C30 and QLQ-LC13) at baseline and then every three weeks until progression. Changes of 10 points or more were considered clinically significant. Analyses of cough, dyspnea and pain symptoms were pre-specified. Time to deterioration (first 10-point worsening from baseline) was analyzed using a stratified log-rank test. Percentage improved/worsened by 10 or more points or stable was measured. Mean scores over time were estimated using longitudinal (mixed-effects growth curve) models.1
About the LUX-Lung 3 Trial
The LUX-Lung 3 trial is a randomized, open-label, Phase III study comparing the investigational, oral, once-daily therapy, afatinib, to a combination chemotherapy regimen as first-line treatment for patients with stage IIIb or IV NSCLC harboring an EGFR mutation. The study randomly assigned 345 patients with EGFR mutation-positive advanced NSCLC to receive afatinib (n=230) or pemetrexed/cisplatin (n=115). The LUX-Lung 3 trial is the largest Phase III trial to date in first-line EGFR mutation-positive, advanced, metastatic NSCLC patients, and the first to use pemetrexed/cisplatin as a comparator in this population. The primary endpoint was progression-free survival (PFS). Secondary endpoints of the LUX-Lung 3 trial included objective response, duration of responses, patient-reported outcomes (including quality of life), safety and overall survival.1
As previously reported, the study met its primary endpoint of PFS with afatinib versus chemotherapy (11.1 versus 6.9 months, respectively) in patients with EGFR mutation-positive advanced NSCLC. The most common drug-related adverse events observed with afatinib were diarrhea (95%), rash (62%), and paronychia (57%). The most common drug-related adverse events observed with chemotherapy (pemetrexed/cisplatin) were nausea (66%), decreased appetite (53%), and vomiting (42%).
Afatinib is an investigational, oral, once-daily irreversible ErbB Family Blocker that specifically inhibits epidermal growth factor receptor (EGFR or ErbB1), human epidermal receptor 2 (HER2 or ErbB2) and ErbB4. It is currently in Phase III clinical development in advanced NSCLC, head and neck and breast cancer. Afatinib is not approved by the FDA; its safety and efficacy have not been established. Boehringer Ingelheim recently submitted a Marketing Authorisation Application (MAA) to the European Medicines Agency (EMA) seeking approval of afatinib as a treatment for patients with EGFR (ErbB1) mutation-positive NSCLC. The company is working on applications for afatinib in a number of countries, including the United States.
