News Release

ESMO 2014, involves providing optimal treatment for patients according to their individual circumstances and the molecular characteristics of their disease.1

"Merck Serono believes in the principle of 'Precision Medicine'; it underpins both our patient- centric approach and our commitment to identifying those patients who would benefit most from our medicines," said Luciano Rossetti, Head of Research and Development, Merck Serono. "The data at ESMO 2014 demonstrates how we put the patient first, and go beyond treatment to support the delivery of focused cancer care, including biomarker testing."

Physician and Patient Understanding of Biomarkers

Findings from a Merck Serono-sponsored global survey of oncologists (n=895)2 from 12 countries (across Asia, Europe and South America) on their use of predictive biomarkers in a range of late-stage and metastatic cancers (lung, breast and colorectal [mCRC]) will be presented during an oral session on Sunday, September 28, 11:00-12:20. The survey also includes physician perceptions of patient understanding of biomarkers and treatment options.

Results from the survey will also be included in an official ESMO 2014 press release and are under strict embargo until 11:00 CET on Sunday, September 28, 2014.

Exploring Biomarkers in mCRC and SCCHN

Retrospective subanalyses from two pivotal Phase III studies for Erbitux® (cetuximab) will be presented as part of Merck Serono's continued effort to further understand biomarkers that may help to inform treatment decisions. The CRYSTAL* study subanalysis evaluates Erbitux plus FOLFIRI (folinic acid, 5-fluorouracil and irinotecan), compared with FOLFIRI alone, in patients with RAS wild-type mCRC, as assessed by liver-limited disease (LLD) status. Further data from the Bonner study assesses the prognostic value of p16 status (p16 positive and p16 negative), a marker of human papillomavirus, in patients with locoregionally advanced squamous cell carcinoma of the head and neck (SCCHN).

News Release Pipeline Data: Targeting Specific Pathways

Merck Serono is presenting data from its diversified early-stage pipeline at ESMO 2014, underscoring the importance of targeting specific pathways. Data include results in difficult-to- treat cancers, as well as in specific patient populations. Highlights include: an oral presentation on results from a Phase Ib study of pimasertib, a MEK inhibitor, in selected genotype-defined solid tumors; pimasertib in combination with SAR245409, a PI3K/MTOR inhibitor; and a number of studies of the highly selective c-Met inhibitor MSC2156119J (EMD 1214063), including a poster discussion of the first-in-human Phase I results in patients with advanced solid tumors. Data will also be presented on abituzumab (DI17E6, EMD 525797) an investigational anti-integrin monoclonal antibody.

About Erbitux

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 over 90 countries for the treatment of colorectal cancer and for the treatment of squamous cell carcinoma of the head and neck (SCCHN).
Merck licensed the right to market Erbitux outside the US and Canada from ImClone LLC, a wholly-owned subsidiary of Eli Lilly and Company, in 1998. In Japan, ImClone, 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.
