• Agreement enables Merck KGaA, Darmstadt, Germany, to further develop abituzumab through a novel risk-sharing collaboration agreement  
  • SFJ Pharmaceuticals Group to develop abituzumab as a first-line treatment for metastatic colorectal cancer (mCRC) in combination with Erbitux® and chemotherapy
  • Clinical program will concentrate on patients with RAS wild-type left-sided tumors with high ανβ6 integrin expression 

DARMSTADT, Germany I May 2, 2018 I Merck KGaA, Darmstadt, Germany, a leading science and technology company which operates its healthcare business in the U.S. and Canada as EMD Serono, today announced a development agreement for investigational molecule abituzumab with SFJ Pharmaceuticals Group (SFJ), a US-based company focused on increasing R&D output and productivity through innovative models.

“Our collaboration with SFJ illustrates Merck KGaA, Darmstadt, Germany’s increasing focus on strategic partnering in order to further diversify our development risks as well as enable a more efficient pipeline prioritization,” said Belén Garijo, member of the Executive Board of Merck KGaA, Darmstadt, Germany, and CEO Healthcare. “Together with SFJ, we aim to progress the understanding of the potential of abituzumab as a targeted treatment for patients suffering from mCRC.”

Merck KGaA, Darmstadt, Germany, has completed Phase II development of abituzumab in combination with Erbitux® and chemotherapy in a second line all-comer patient population with KRAS wild-type mCRC. In this Phase II study, a subgroup of patients with overexpression of integrin αvβ6 was identified as potentially benefiting from this treatment.[1] With the evolving understanding of the relationship between mCRC tumor location and treatment outcomes in recent years, SFJ will pursue the combination of abituzumab, Erbitux® and chemotherapy in a first-line setting in high ανβ6-expressing patients who have RAS wild-type left-sided mCRC.[2-3]

In a novel innovation model recently emerging in the biopharma industry, SFJ – one of the pioneers of such collaborations – will finance and also be responsible for Phase II/III development of abituzumab. The agreement reflects Merck KGaA, Darmstadt, Germany’s strategic approach to collaborations, identifying those opportunities that can progress the company’s highly promising clinical stage assets through novel innovation models. Both Merck KGaA, Darmstadt, Germany, and SFJ have agreed not to disclose the terms of the deal.

“We are delighted to partner with Merck KGaA, Darmstadt, Germany, to pursue this new clinical development project,” said Robert DeBenedetto, Chief Executive Officer of SFJ. “Our expertise in oncology and renowned ability to successfully carry out various late stage clinical development projects is gaining wider acceptance and enables industry players like Merck KGaA, Darmstadt, Germany, to develop their promising assets by risk-sharing with us.”

About Abituzumab  

Abituzumab is an investigational pan-αν integrin inhibiting monoclonal antibody with activity against αvβ1, 3, 5, 6 and 8 integrin heterodimers. By interfering with the TGF-β latency associated peptide via inhibition of the ανβ6 integrin, it has a potential for treating solid tumors such as colorectal cancer.[4] Abituzumab is currently under clinical investigation and not approved for any use anywhere in the world.

About Erbitux® (cetuximab) 

Erbitux® is a 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. Erbitux also targets cytotoxic immune effector cells towards EGFR expressing tumor cells (antibody dependent cell-mediated cytotoxicity, ADCC).

The most commonly reported side effect with Erbitux is an acne-like skin rash. 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 over 90 countries world-wide for the treatment of RAS wild-type metastatic colorectal cancer and for the treatment of squamous cell carcinoma of the head and neck (SCCHN). Merck KGaA, Darmstadt, Germany licensed the right to market Erbitux, a registered trademark of ImClone LLC, outside the U.S. and Canada from ImClone LLC, a wholly-owned subsidiary of Eli Lilly and Company, in 1998.
