November 19, 2017

Bayer Pharmaceuticals Corporation (NYSE: BAY) and Onyx Pharmaceuticals, Inc (Nasdaq: ONXX) announced the availability of sorafenib (BAY 43-9006) through a treatment protocol for eligible individuals with advanced renal cell carcinoma (RCC), or kidney cancer.

Sorafenib is being made available to patients through qualified investigators participating in this program at clinical sites throughout the United States The protocol, known as the Advanced Renal Cell Carcinoma Sorafenib (ARCCS) study, has been reviewed by the U.S. Food and Drug Administration (FDA). To be eligible, individuals with advanced kidney cancer may not have been previously treated with sorafenib. Interested patients should ask their physicians to call: 1-866-639-2827 for more information. Discussions with regulators outside the United States, about similar programs in other territories, are anticipated to begin soon.

"We have been encouraged by the results of our clinical trials to date and look forward to initiating this open-label treatment protocol for individuals with advanced kidney cancer," said Susan Kelly, M.D., vice president, Oncology, Bayer Pharmaceuticals Corporation.

Sorafenib is currently being studied in the largest randomized, controlled trial ever conducted in advanced RCC. Dr. Bernard Escudier, Head of Immunotherapy and Innovative Therapy Unit at the Gustave-Roussy Institute, Paris, France, and co-principal investigator of the study, today reported that disease progression was significantly delayed in those patients who received sorafenib. As assessed by independent radiologic review, a measure of disease progression called progression-free survival (PFS) was doubled to a median value of 24 weeks (167 days) in patients receiving sorafenib as compared to 12 weeks (84 days) for patients receiving placebo (p-value< 0.000001). Bayer and Onyx are currently preparing a New Drug Application (NDA) for possible approval in this indication by the US Food and Drug Administration (FDA) in the United States. Discussions are also underway with regulatory agencies about registration in other territories.

"New approaches to treating kidney cancer are clearly needed and the recently announced sorafenib results are encouraging for individuals suffering from this type of cancer," said Bill Bro, president of the Kidney Cancer Association. "This protocol, which will provide access to treatment for many more patients, is welcome news."

About Sorafenib

Sorafenib, a novel investigational drug candidate, is the first oral multi-kinase inhibitor that targets serine/threonine and receptor tyrosine kinases in both the tumor cell and tumor vasculature. In preclinical models, sorafenib targeted members of two classes of kinases known to be involved in both tumor cell proliferation (tumor growth) and tumor angiogenesis (tumor blood supply) - two important cancer growth activities. These kinases included RAF kinase, VEGFR-2, VEGFR-3, PDGFR-, KIT, FLT-3 and RET.
