Merck KGaA Presented New Data On the Combination of Erbitux with Standard First-Line Therapy in Patients with NSCLC
- Results reported from a meta-analysis including 2,018 NSCLC patients show a benefit across all efficacy endpoints for adding Erbitux to standard first-line therapy
- Erbitux is the first and only targeted compound in clinical development in more than 10 years to increase overall survival in a NSCLC patient population including all histologies
San Francisco, CA, USA / Darmstadt, Germany, August 1/2, 2009
– New data from a meta-analysis of trials evaluating the
addition of Merck KGaA’s Erbitux® (cetuximab) to standard
first-line chemotherapy in patients with non-small cell lung cancer
(NSCLC) was presented today at the International Association for
the Study of Lung Cancer’s 13th World Conference on Lung
Cancer (WCLC) in San Francisco.
“The meta-analysis showed the benefit for Erbitux for all investigated endpoints across a broad patient population in the first-line NSCLC setting,” said Professor Nick Thatcher, Christie Hospital NHS Trust, Manchester, UK. “The survival benefit, seen irrespective of which standard chemotherapy regimen was used, shows Erbitux may have an important role in the treatment of NSCLC.”
“This meta-analysis shows significant results across all efficacy endpoints, including response rate, progression-free survival and overall survival, in trials that include all histological types of NSCLC for Erbitux in combination with standard platinum doublets adding further evidence to the already published results of the FLEXa study," said Dr. Wolfgang Wein, Executive Vice President Oncology of the division Merck Serono.
In Europe, lung cancer is the leading cause of death from cancer, accounting for 20% of all cancer deaths (28% in men and 10% in women).6 NSCLC accounts for approximately 80% of all lung cancer cases.7 At diagnosis, most patients with NSCLC present with advanced, non-operable (also called unresectable) disease, which is associated with a very poor prognosis.8 The overall 5-year survival rate for lung cancer is about 10%, compared to 81% for melanoma and 75% for breast cancer.9
Erbitux is already established as a standard in the treatment of metastatic colorectal cancer and squamous cell carcinoma of the head and neck.
Merck has submitted an application to the European Medicines Agency (EMEA) to license Erbitux for first-line treatment of NSCLC. Following the negative decision of the CHMP Merck Serono has requested re-examination of this opinion.

Erbitux is a first-in-class and highly active IgG1 monoclonal antibody targeting the epidermal growth factor receptor (EGFR). As a monoclonal antibody, the mode of action of Erbitux is distinct from standard non-selective chemotherapy treatments in that it specifically targets and binds to the EGFR. This binding inhibits the activation of the receptor and the subsequent signal-transduction pathway, which results in reducing both the invasion of normal tissues by tumor cells and the spread of tumors to new sites. It is also believed to inhibit the ability of tumor cells to repair the damage caused by chemotherapy and radiotherapy and to inhibit the formation of new blood vessels inside tumors, which appears to lead to an overall suppression of tumor growth.
The most commonly reported side effect with Erbitux is an acne-like skin rash that seems to be correlated with a good response to therapy. In approximately 5% of patients, hypersensitivity reactions may occur during treatment with Erbitux; about half of these reactions are severe.
Erbitux has already obtained market authorization in 76 countries. It has been approved for the treatment of colorectal cancer in 76 countries and for the treatment of squamous cell carcinoma of the head and neck (SCCHN) in 71 countries:
· December 2003 (Switzerland), February 2004 (USA), June 2004 (EU) and followed by other countries: for use in combination with irinotecan in patients with EGFR-expressing mCRC (metastatic colorectal cancer) who have failed prior irinotecan therapy. In addition, Erbitux is also approved for single-agent use in further countries.
· April 2006 (EU) and followed by other countries: for use in combination with radiotherapy for the treatment of locally advanced squamous cell carcinoma of the head and neck (SCCHN). In further countries, Erbitux is also approved as monotherapy in patients with recurrent and/or metastatic SCCHN who failed prior chemotherapy.
· July 2008 (EU): license was updated for the treatment of patients with epidermal growth factor receptor (EGFR) expressing, KRAS wild-type mCRC in combination with chemotherapy and as a single agent in patients who have failed oxaliplatin-and irinotecan-based therapy and who are intolerant to irinotecan.
· July 2008 (Japan): for use in combination with irinotecan in patients with EGFR-expressing mCRC who have failed prior irinotecan therapy
· In November 2008 (EU): license was updated for the use in combination with platinum-based chemotherapy in patients with recurrent and/or metastatic SCCHN
Merck licensed the right to market Erbitux outside the US and Canada from ImClone Systems, a wholly-owned subsidiary of Eli Lilly and Company, in 1998. In Japan, ImClone Systems, Bristol-Myers Squibb Company and Merck jointly develop and commercialize Erbitux. Merck has an ongoing commitment to the advancement of oncology treatment and is currently investigating novel therapies in highly targeted areas, such as the use of Erbitux in colorectal cancer, squamous cell carcinoma of the head and neck and non-small cell lung cancer. Merck has also acquired the rights for the cancer treatment UFT® (tegafur-uracil) – an oral chemotherapy administered with folinic acid (FA) for the first-line treatment of metastatic colorectal cancer.
Merck is also investigating among other cancer treatments the use of Stimuvax® (formerly referred to as BLP25 Liposome Vaccine) in the treatment of non-small cell lung cancer. The vaccine was granted fast-track status in September 2004 by the FDA. Merck obtained the exclusive worldwide licensing rights from Oncothyreon Inc., Seattle, Washington, USA.
In addition, Merck is developing Cilengitide, which is the first in a new class of investigational anti-cancer therapies called integrin inhibitors to reach Phase III of development; it is currently being investigated for the treatment of glioblastoma, SCCHN and NSCLC. Integrin inhibitors are thought to work by targeting the tumor and its vasculature
