Boehringer Ingelheim to present new data at ASCO annual meeting regarding its investigational compound afatinib in EGFR-mutation positive patients with advanced NSCLC

May 25, 2011

RIDGEFIELD, Conn., May 25 /PRNewswire/ – Boehringer Ingelheim Pharmaceuticals, Inc. will present new phase Ib data at the 2011 American Society of Clinical Oncology (ASCO) annual meeting in Chicago (June 3-7) that indicates combining its investigational therapy afatinib (BIBW 2992) with cetuximab at the maximum tested dose controlled disease in all (n=22) treated epidermal growth factor receptor (EGFR)-mutation positive patients with non-small cell lung cancer (NSCLC) who developed acquired resistance to treatment with a reversible EGFR tyrosine kinase inhibitor (TKI). Researchers observed a tumor size reduction of up to 76 percent over a treatment period of up to five months.(1) The most common drug-related adverse events were rash and diarrhea, with three patients (11.5%) experiencing Grade 3 rash. Afatinib is an orally-administered irreversible inhibitor of the erbB family of receptor tyrosine kinases, specifically EGFR and HER2. It is in late-stage development in advanced NSCLC and breast cancer.

Boehringer Ingelheim and QIAGEN are pleased that ASCO and the National Comprehensive Cancer Network (NCCN), two leading oncology organizations, recently recommended EGFR mutation testing for patients with metastatic or recurrent NSCLC. These recommendations underscore the importance of genetic tumor testing to predict patient response to certain treatments, enabling personalized healthcare. Boehringer Ingelheim has partnered with QIAGEN to develop a real-time polymerase chain reaction assay (real-time PCR) companion diagnostic test for afatinib that, if approved, could help physicians identify which patients may benefit from EGFR-targeted therapies.

“The ASCO and NCCN EGFR mutation testing recommendations reinforce the importance of identifying the appropriate NSCLC patients for clinical trials,” said Christopher Corsico, M.D., M.P.H., Senior Vice President, Medicine and Regulatory, Boehringer Ingelheim Pharmaceuticals, Inc. “Boehringer Ingelheim is committed to studying afatinib in patients with advanced NSCLC with EGFR mutations, in addition to other patient populations.”

About the Afatinib Data to be Presented at 2011 ASCO Annual Meeting

This phase Ib study involved 26 EGFR-mutation positive patients with NSCLC who acquired resistance to a reversible EGFR TKI (erlotinib or gefitinib), potentially due to the emergence of a second mutation called T790M. The T790M mutation is found in roughly 50 percent of the tumors from patients who develop acquired resistance to reversible EGFR TKIs.(2) Patients in the study received afatinib 40 mg daily with escalating dose cohorts of bi-weekly cetuximab at 250 and 500 mg/m2. Tumor tissue was collected at or after the emergence of acquired resistance for genetic testing.(1)

Twenty-two of the 26 patients in the study received the pre-defined maximum dose of afatinib 40 mg daily plus cetuximab 500 mg/m2. The most common drug-related adverse events were Grade 1/2 rash (35% and 46%, respectively) and Grade 1/2 diarrhea (50% and 19%, respectively). Three patients (11.5%) experienced Grade 3 rash. In addition to the disease control rates observed, confirmed partial responses were seen in 36 percent (8/22) of evaluable patients (95% confidence interval [CI]: 0.17-0.59), including 29 percent of patients (4/13) who were found to have the T790M mutation. Updated data will be available during the poster presentation at ASCO. The study has since been expanded to enroll 80 patients; results will be presented at a future conference.(1)

Boehringer Ingelheim will also present data at the ASCO annual meeting from several additional studies evaluating afatinib in patients with NSCLC, brain metastases and glioblastoma, and other advanced solid tumors.

About the ASCO Provisional Clinical Opinion and NCCN Clinical Practice Guidelines

Based on the growing body of research, ASCO issued a provisional clinical opinion in April 2011 stating that patients with NSCLC who are being considered for first-line therapy with an EGFR TKI should have their tumor tested for EGFR mutations to determine whether an EGFR TKI or chemotherapy is the appropriate first-line therapy.(3) Earlier this year, NCCN updated its clinical practice guidelines to include a category 1 recommendation for EGFR testing after a histologic diagnosis of adenocarcinoma, large cell carcinoma or undifferentiated carcinoma.(4)

It is believed that approximately 5-20 percent of NSCLC patients have mutations of the EGFR tyrosine kinase, with an increased frequency in patients with adenocarcinoma, Asian ethnicity and former/nonsmoking status.(5,6)

About Afatinib

Afatinib is an investigational compound. Afatinib is not approved by the FDA; its safety and efficacy have not been established.

Afatinib is an orally-administered irreversible inhibitor of the erbB family of receptor tyrosine kinases, specifically EGFR and HER2. It is in late-stage development in several solid tumors including advanced NSCLC and breast cancer.

About the Afatinib Clinical Program

Boehringer Ingelheim is actively developing targeted therapies – biologicals and small molecules – in areas of unmet medical need. This includes both solid and hematological cancers. The company’s comprehensive LUX clinical trial program includes, among other trials, more than 10 registration trials investigating afatinib for potential approval for a variety of solid tumor types, including NSCLC, breast and head and neck cancer.

LUX-Lung 1 was a phase IIb/III trial investigating afatinib plus best supportive care (BSC) versus placebo plus BSC in NSCLC patients who were previously treated with first-line chemotherapy and the reversible EGFR TKIs erlotinib or gefitinib.

LUX-Lung 2 is a phase II trial evaluating afatinib in NSCLC patients with EGFR mutations, either treatment naïve or after one line of chemotherapy.

Boehringer Ingelheim recently completed enrollment in the phase III LUX-Lung 3 trial that will specifically investigate afatinib as a first-line treatment in patients with advanced NSCLC with EGFR mutations. Another ongoing phase III trial, LUX-Lung 6, also investigates the efficacy and safety of afatinib compared to standard chemotherapy for first-line treatment of NSCLC patients with EGFR mutations in different geographical regions.

LUX-Lung 4 is a phase I/II trial of afatinib in NSCLC patients who have progressed after conventional EGFR-TKI treatment.

LUX-Lung 5 is a global phase III trial in patients previously treated with erlotinib or gefitinib. This is the first randomized phase III trial investigating whether patients who initially benefit from treatment with afatinib alone may further benefit from afatinib beyond progression when given in combination with chemotherapy.

About Lung Cancer

Lung cancer is the second most common cancer and kills more people than any other cancer. In 2010, approximately 222,520 new cases of lung cancer were diagnosed in the United States, with 157,300 Americans dying from the disease. NSCLC is the most common form of lung cancer, accounting for about 85 percent of all lung cancers.(7) Lung cancer remains an area of high unmet need, especially in its advanced stages where it is particularly aggressive and patients have limited treatment options.
