Pfizer Oncology to Showcase New Data from Innovative Science That Address Patient Needs at ASCO 2019 Annual Meeting

Pfizer Inc. (NYSE:PFE) will present data across its industry-leading oncology portfolio, covering multiple tumor types and mechanisms of action at the 55th Annual Meeting of the American Society of Clinical Oncology (ASCO) in Chicago from May 31-June 4, 2019. Data will highlight Pfizer’s cutting-edge approach, expertise in precision medicine and work in immunotherapy combinations, including company-sponsored and collaborative research studies.

"The data presented at this year’s ASCO showcase our continued commitment to follow the science, whether it’s expanding our approved medicines for breast and prostate cancers into new populations and lines of therapy, or exploring the important role of biomarkers and immunotherapy combinations,” said Dany Habr, M.D., Chief Medical Officer, Pfizer Oncology. "We look forward to both sharing our exciting data in these and other tumor types, as well as connecting with our research partners to determine how we can continue to work collaboratively to bring transformative therapies to our cancer patients.”

The research to be presented includes new insights on Pfizer’s marketed therapies, including IBRANCE^® (palbociclib), XTANDI^® (enzalutamide), TALZENNA^® (talazoparib), BOSULIF^® (bosutinib), INLYTA^® (axitinib) and BAVENCIO^® (avelumab), which represent Pfizer Oncology’s long-standing legacy of developing innovative therapies for patients in need, as well as its ongoing commitment to addressing the needs of cancer patients across gender, ethnicity and tumor type. For example, Pfizer will present real-world data on the use of IBRANCE for the treatment of men with metastatic breast cancer (MBC).

"At this year’s ASCO, I am particularly excited that we’ll share data from new initiatives such as the oral presentation of talazoparib in breast cancer or other solid tumors. This builds on a productive year with the approval of four new oncology treatments, three biosimilars and three new indications, including one based on real-world evidence,” said Chris Boshoff, M.D., Ph.D., Chief Development Officer, Oncology, Pfizer Global Product Development. "We are proud to have one of the broadest oncology portfolios in the industry, and a research philosophy that puts patients first, embraces new approaches and showcases innovative thinking.”

Key Pfizer-sponsored, investigator-sponsored and collaborative research abstracts leveraging the depth of Pfizer’s scientific advances include:

• A poster presentation on real-world evidence of male breast cancer patients treated with IBRANCE in combination with endocrine therapy (Abstract 1055).
• An external investigator-sponsored oral presentation on a Phase 2 trial examining TALZENNA beyond BRCA, specifically as monotherapy in BRCA1 and BRCA2 wild-type patients with advanced HER2-negative breast cancer or other solid tumors with a mutation in homologous recombination (HR) pathway genes (Investigator-sponsored abstract 3006).
• Biomarker analyses from JAVELIN Renal 101 that studied BAVENCIO plus INLYTA vs. sunitinib in advanced renal cell carcinoma (aRCC) (Abstract 101).
• An external collaborative research presentation on genomic markers of early progression on fulvestrant with or without IBRANCE for ER+ advanced breast cancer in the PALOMA-3 trial (Collaborative research abstract 1010).
