Merck KGaA, Darmstadt, Germany, and Pfizer today announced that 13 avelumab* abstracts across seven challenging tumor types will be featured at the 53rd American Society of Clinical Oncology (ASCO) Annual Meeting held June 2-6, 2017 in Chicago, IL. Key presentations include data for avelumab in first-line metastatic Merkel cell carcinoma (mMCC) and in previously treated metastatic urothelial carcinoma (UC), as well as results from the Phase Ib trial investigating avelumab in combination with the tyrosine kinase inhibitor axitinib, in advanced renal cell carcinoma (RCC).

    
"Our ASCO presence adds to what has already been a momentous year for the alliance, coming shortly after the US FDA granted two accelerated approvals for avelumab," 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're particularly excited to share the latest avelumab data in both metastatic Merkel cell carcinoma in the first-line setting and previously treated metastatic urothelial carcinoma with the cancer community."

"Our data at ASCO this year underscore the potential of avelumab as a monotherapy treatment, as well as part of combination regimens," said Chris Boshoff, M.D., PhD, Senior Vice President and Head of Immuno-Oncology, Early Development, Translational Oncology, Pfizer Global Product Development. "Now with accelerated approvals in two indications for avelumab in the US, we are entering the next chapter of our clinical development program to provide meaningful new treatment options for patients who need them most."

Highlights of avelumab data at ASCO 2017 include the following:

Preliminary data from the ongoing JAVELIN Merkel 200 trial, an open-label, multicenter study conducted in first-line mMCC investigating avelumab in patients who had no prior systemic treatment for mMCC, will be presented for the first time at a medical congress.
Data from a pooled analysis of two metastatic UC cohorts of the JAVELIN Solid Tumor trial, a Phase Ib, open-label, single-arm, multicenter study of avelumab in the treatment of various solid tumors, will be presented.
An oral presentation of results from the JAVELIN Renal 100 trial, a Phase Ib, open-label study evaluating the clinical activity and safety of the combination of avelumab and axitinib for the first-line treatment of advanced RCC.
Beyond mMCC, metastatic UC and advanced RCC, the alliance between Merck KGaA, Darmstadt, Germany, and Pfizer will also showcase avelumab abstracts in non-small cell lung cancer, metastatic castrate-resistant prostate cancer, locally advanced squamous cell carcinoma of the head and neck and relapsed or refractory diffuse large B-cell lymphoma, as well as updated pooled safety data in solid tumors.
The alliance's JAVELIN clinical development program now involves at least 30 clinical programs, including nine Phase III trials, and more than 5,200 patients across more than 15 tumor types. Results from JAVELIN program trials have supported two FDA accelerated approvals in 2017.

A list of accepted avelumab abstracts is included below. The abstracts are also available on the ASCO website.

*Avelumab is under clinical investigation for treatment of NSCLC, RCC, DLBCL, SSCHN and mCRPC and has not been demonstrated to be safe and effective for these indications. There is no guarantee that avelumab will be approved for NSCLC, RCC, DLBCL, SSCHN and mCRPC by any health authority worldwide.

About Avelumab

Avelumab is a human antibody specific for a protein called PD-L1, or programmed death
ligand-1. Avelumab is designed to potentially engage both the adaptive and innate immune systems. By binding to PD-L1, avelumab is thought to prevent tumor cells from using PD-L1 for protection against white blood cells, such as T-cells, exposing them to anti-tumor responses. Avelumab has been shown to induce antibody-dependent cell-mediated cytotoxicity (ADCC) in vitro. In November 2014, Merck KGaA, Darmstadt, Germany, and Pfizer announced a strategic alliance to co-develop and co-commercialize avelumab.

Indications 

The US Food and Drug Administration (FDA) granted accelerated approval for avelumab (BAVENCIO®) for the treatment of (i) metastatic Merkel cell carcinoma (mMCC) in adults and pediatric patients 12 years and older and (ii) patients with locally advanced or metastatic urothelial carcinoma (UC) who have disease progression during or following platinum-containing chemotherapy, or who have disease progression within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy. Continued approval for these indications may be contingent upon verification and description of clinical benefit in confirmatory trials. Avelumab is not approved for any indication in any market outside the US.

Important Safety Information 

The warnings and precautions for BAVENCIO include immune-mediated adverse reactions (such as pneumonitis, hepatitis, colitis, endocrinopathies, nephritis and renal dysfunction and other adverse reactions), infusion-related reactions and embryo-fetal toxicity.

Common adverse reactions (reported in at least 20% of patients) in patients treated with avelumab include fatigue, musculoskeletal pain, diarrhea, nausea, infusion-related reaction, peripheral edema, decreased appetite/hypophagia, urinary tract infection and rash.

For full prescribing information and medication guide for BAVENCIO, please see http://www.BAVENCIO.com.

Alliance between Merck KGaA, Darmstadt, Germany, and Pfizer Inc., New York, US

The information contained in this release is as of May 17, 2017. Pfizer assumes no obligation to update forward-looking statements contained in this release as the result of new information or future events or developments.

This release contains forward-looking information about BAVENCIO (avelumab), the alliance between Merck KGaA, Darmstadt, Germany, and Pfizer involving anti-PD-L1 and anti-PD-1 therapies, and clinical development plans, including their potential benefits, that involves substantial risks and uncertainties that could cause actual results to differ materially from those expressed or implied by such statements. Risks and uncertainties include, among other things, uncertainties regarding the commercial success of BAVENCIO; the uncertainties inherent in research and development, including the ability to meet anticipated clinical study commencement and completion dates and regulatory submission dates, as well as the possibility of unfavorable study results, including unfavorable new clinical data and additional analyses of existing clinical data; risks associated with interim data; the risk that clinical trial data are subject to differing interpretations, and, even when we view data as sufficient to support the safety and/or effectiveness of a product candidate, regulatory authorities may not share our views and may require additional data or may deny approval altogether; whether and when drug applications may be filed in any jurisdictions for potential indications for BAVENCIO, combination therapies or other product candidates; whether and when any such applications (including the pending application for BAVENCIO for metastatic Merkel cell carcinoma in the EU) may be approved by regulatory authorities, which will depend on the assessment by such regulatory authorities of the benefit-risk profile suggested by the totality of the efficacy and safety information submitted; decisions by regulatory authorities regarding labeling and other matters that could affect the availability or commercial potential of BAVENCIO, combination therapies or other product candidates; and competitive developments.

A further description of risks and uncertainties can be found in Pfizer's Annual Report on Form 10-K for the fiscal year ended December 31, 2016, and in its subsequent reports on Form 10-Q, including in the sections thereof captioned "Risk Factors" and "Forward-Looking Information and Factors That May Affect Future Results", as well as in its subsequent reports on Form 8-K, all of which are filed with the U.S. Securities and Exchange Commission and available at http://www.sec.gov and http://www.pfizer.com.
