On October 31, 2016 Merck KGaA, Darmstadt, Germany, and Pfizer Inc. (NYSE: PFE (link is external)) reported that the European Medicines Agency (EMA) has validated for review Merck KGaA, Darmstadt, Germany’s Marketing Authorization Application (MAA) for avelumab, for the proposed indication of metastatic Merkel cell carcinoma (MCC), a rare and aggressive skin cancer, which impacts approximately 2,500 Europeans a year (Press release, Pfizer, OCT 31, 2016, View Source [SID1234516116]).[1],[2] Validation of the MAA confirms that submission is complete and begins the EMA’s centralized review process.* If approved, avelumab, an investigational fully human anti-PD-L1 IgG1 monoclonal antibody, could be the first approved treatment indicated for metastatic MCC in the EU. Patients with metastatic MCC face a very poor prognosis, with less than 20 percent surviving beyond five years.[3] Schedule your 30 min Free 1stOncology Demo! "While early-stage Merkel cell carcinoma can be generally managed with surgery, there are significant unmet needs in metastatic disease, where treatment options are severely limited," said Luciano Rossetti, M.D., Executive Vice President, Global Head of Research & Development at the biopharma business of Merck KGaA, Darmstadt, Germany, which in the US and Canada operates as EMD Serono. "We are pleased that the EMA is initiating its review of avelumab, as this means we are one step closer to bringing a much-needed new treatment option to European patients."

"This is the first of what we hope will be many regulatory milestones for avelumab," said Chris Boshoff, M.D., Ph.D., Senior Vice President and Head of Immuno-oncology, Early Development and Translational Oncology, Pfizer Global Product Development. "We are committed to evaluating avelumab in a number of hard-to-treat cancers, and we believe it may have potential to be an important treatment option for patients with metastatic Merkel cell carcinoma."
The avelumab metastatic MCC MAA submission is supported by data from JAVELIN Merkel 200, a multicenter, single-arm, open-label, Phase II study of 88 patients with metastatic MCC whose disease had progressed after at least one chemotherapy treatment.[1] The JAVELIN Merkel 200 study represents the largest data set of any anti-PD-L1/PD-1 antibody reported in this patient population. These data were recently published in the Lancet Oncology.[1]
Avelumab received an Orphan Drug Designation (ODD) from the European Commission for MCC. To qualify for an ODD in the EU, a medicine must be intended for the treatment, prevention or diagnosis of a disease that is life-threatening or chronically debilitating; the prevalence of the condition in the EU must not be more than 5 in 10,000, or it must be unlikely that marketing of the medicine would generate sufficient returns to justify the investment needed for its development; and it must be for a disease where no satisfactory treatment is currently available.[4]
The clinical development program for avelumab, known as JAVELIN, involves at least 30 clinical programs and over 2,900 patients evaluated across more than 15 different tumor types. In addition to metastatic MCC, these cancers include breast, gastric/gastro-esophageal junction, head and neck, Hodgkin’s lymphoma, melanoma, mesothelioma, non-small cell lung, ovarian, renal cell carcinoma and urothelial (primarily bladder).
*Avelumab is not approved for any indication in any market. This marks the first acceptance of an EU market authorization application to review the safety and efficacy results for the investigational product avelumab.
