Pfizer invests more than 20 percent of its development budget in oncology research with active programs in immunotherapy, signal transduction inhibition, and angiogenesis inhibition. During the past five years, the number of R&D oncology projects in Pfizer has increased four-fold. In addition to the approximately 30 programs in preclinical development, 16 Pfizer oncology compounds are in Phase I-III clinical development including four compounds currently in phase II and three compounds, as well as a potential additional indication for Sutent, currently in phase III.

“We have had a clear and sustained focus on advancing our oncology clinical program and we are making significant progress as demonstrated by the depth and breadth of scientific presentations at ASCO,” said Dr. Charles Baum, vice president of Pfizer Global Research and Development.

“We have compounds in Phase III, or nearing Phase III, which address more than 70 percent of deaths due to various cancer types. We continue to move our pipeline closer to regulatory submissions and closer to broad availability for the cancer patients that could benefit from them.”

At ASCO, extensive data presentations were made concerning long-established Pfizer oncology medicines, including Camptosar and Aromasin. More than 50 additional abstracts discussed new data on the new medicine Sutent and on nine compounds in Pfizer’s broad and deep new-product pipeline in oncology.
