Pfizer Presents Scientific Advancements from its Leading Oncology Portfolio at ASCO 2023 Annual Meeting

Pfizer Inc. (NYSE: PFE) will present data across its Oncology portfolio and growing pipeline, covering multiple tumor types and novel mechanisms of action at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago from June 2 through June 6. Abstracts include new data from pivotal trials supporting ongoing regulatory reviews for three potential therapies, if approved, and new clinical data for six early pipeline assets. In addition, Pfizer will highlight its ongoing scientific leadership in breast cancer with additional real-world evidence (RWE) for IBRANCE® (palbociclib) and initial first-in-human results for its novel CDK4- and CDK2-selective inhibitors, respectively, and novel epigenetic modulator KAT6 inhibitor.

“At ASCO, Pfizer will present new data across the four key areas of our industry-leading portfolio – breast cancer, genitourinary cancer, hematology, and precision medicine – and for the first time, first-in-human data for some of our most exciting pipeline medicines,” said Chris Boshoff, M.D., Ph.D., Chief Development Officer, Oncology and Rare Disease, Pfizer Global Product Development. “With four anticipated regulatory decisions this year and a growing portfolio of multiple mechanisms of action, Pfizer Oncology is poised to take our scientific innovation to the next level and bring new hope to people with cancer.”

Today, Pfizer Oncology has a comprehensive portfolio of 24 approved innovative cancer medicines and biosimilars to treat more than 30 cancer types and an extensive pipeline of more than 30 programs in clinical development. With the recently announced proposed acquisition of Seagen*, a leader in antibody-drug conjugate technology, Pfizer is further accelerating its fight against cancer to deliver the next generation of Oncology breakthroughs.

“Placing patients at the center of everything we do is a critical component of advancing cutting-edge science and improving outcomes for patients,” said Dany Habr, M.D., Oncology Chief Medical Affairs Officer, Pfizer. “At ASCO, we look forward to connecting with the entire Oncology community to continue our efforts and shared approaches in making scientific breakthroughs accessible to all people living with cancer, everywhere.”

Pfizer’s commitment to advancing scientific innovation will be on display at ASCO 2023 with more than 40 company-sponsored abstracts. Highlights include:

13 abstracts across the comprehensive MagnetisMM clinical trial program reinforcing the efficacy and safety of elranatamab, an investigational subcutaneous B-cell maturation antigen (BCMA)-CD3-targeted bispecific antibody, in relapsed or refractory multiple myeloma (RRMM), including an oral presentation on the first data from patients treated with prior BCMA-targeted therapy. Elranatamab is under Priority Review with the U.S. Food and Drug Administration (FDA) and under review with the European Medicines Agency (EMA) for the treatment of RRMM.
Four abstracts, including an oral presentation on new additional data from the Phase 3 TALAPRO-2 study, supporting the potential of TALZENNA® (talazoparib), an oral poly ADP-ribose polymerase (PARP) inhibitor that plays a role in DNA damage repair, in combination with XTANDI® (enzalutamide), an androgen receptor signaling inhibitor, in men with metastatic castration-resistant prostate cancer. The FDA has granted Priority Review for the Supplemental New Drug Application (sNDA) for TALZENNA in combination with XTANDI and an application is also under review with the EMA.
For the first time, the primary efficacy and safety results from the Phase 2 PHAROS trial exploring BRAFTOVI® (encorafenib), an oral BRAF kinase inhibitor, given in combination with MEKTOVI® (binimetinib), an oral MEK inhibitor, in patients with metastatic non-small cell lung cancer harboring a BRAF V600E mutation.** Results from the PHAROS study support the sNDAs for BRAFTOVI and MEKTOVI in this setting that are currently under review by the FDA.
Advancements across Pfizer’s leading breast cancer portfolio and pipeline, including a new analysis of real-world evidence for IBRANCE, an oral first-in-class inhibitor of cyclin-dependent kinases (CDKs) 4 and 6, as a first-line treatment of metastatic breast cancer. In addition, the first Phase 1 data for the CDK4-selective inhibitor PF-07220060, the CDK2-selective inhibitor PF-07104091 and the KAT6 inhibitor PF-07248144, all investigational agents for advanced or metastatic hormone-receptor positive breast cancer, will be presented.
