JAVELIN Bladder 100 Study to be presented in Plenary Session and featured in the official Press Program

NEW YORK–(BUSINESS WIRE)–Pfizer Inc. (NYSE: PFE) today announced that new data from clinical trials of 18 approved and investigational medicines will be presented virtually at the ASCO20 Virtual Scientific Program, from May 29-May 31. The data that will be presented build on Pfizer’s strong track record in oncology by providing new insights in areas like breast, colorectal and genitourinary cancers, which include bladder, prostate, and kidney cancer. Data from Pfizer’s early stage pipeline, including a novel anti-HER2 antibody-drug conjugate, will also be presented as Pfizer aims to transform the cancer treatment landscape well into the future.

“Our data presentations will highlight the depth and breadth of our cancer portfolio, including our current medicines and new generation of potential therapies,” said Chris Boshoff, M.D., Ph.D., Chief Development Officer, Oncology, Pfizer Global Product Development. “We are particularly excited to share the first presentation of detailed overall survival results from the JAVELIN Bladder 100 trial of BAVENCIO and the final overall survival data from the PROSPER trial of XTANDI. These data will support our rapidly expanding efforts in bladder cancer and add to the growing body of clinical evidence generated with XTANDI in prostate cancer.”

New data will be featured in nine oral presentations, including a Plenary Session presentation of data from the JAVELIN Bladder 100 trial evaluating BAVENCIO^® (avelumab) as a first-line maintenance treatment for locally advanced or metastatic urothelial carcinoma (UC). Additional data provide insights on Pfizer’s medicines, including IBRANCE^® (palbociclib), BRAFTOVI^® (encorafenib), XTANDI^® (enzalutamide) and lorlatinib, as well as its cutting-edge, investigational compounds, including a HER2-targeted antibody-drug conjugate in patients with solid tumors.
