NEW YORK--( BUSINESS WIRE )--Pfizer Inc. (NYSE: PFE) continues to showcase potential practice-changing research and next-generation candidates across its robust Oncology portfolio at the European Society for Medical Oncology (ESMO) Congress 2024, being held September 13-17 in Barcelona. Data from more than 50 company-sponsored, investigator-sponsored and collaborative research abstracts, including more than 10 oral and mini-oral presentations, will be presented across the company’s tumor areas and core scientific modalities, as well as a potential treatment for a cancer-related condition. “ At this year’s ESMO, we are looking forward to demonstrating our progress toward delivering next-generation biologics and novel combinations that have the potential to be new standards of care for patients,” said Chris Boshoff, Chief Oncology Officer and Executive Vice President, Pfizer. “ Our key data presentations highlight our scientific leadership in developing targeted therapies, including small molecules and antibody-drug conjugates, across our core tumor areas, including breast, bladder and thoracic cancers.” “ At ESMO, Pfizer will share important data highlighting our commitment to transforming outcomes for patients living with lung cancer, including longer-term follow-up results from the BRAFTOVI + MEKTOVI PHAROS study in BRAF V600E-mutated metastatic non-small cell lung cancer,” said Karin Tollefson, Chief Oncology Medical Officer, Pfizer. “ We are also looking forward to sharing progress on our industry-leading pipeline of new molecules, including encouraging early results for two novel, investigational antibody-drug conjugates and preliminary data on a novel combination of Pfizer’s next-generation CDK inhibitors.” Key research includes a late-breaking presentation of updated results from the pivotal Phase 2 PHAROS* study of BRAFTOVI (encorafenib) + MEKTOVI (binimetinib) in patients with BRAF V600E-mutant metastatic non-small cell lung cancer (mNSCLC). Longer-term efficacy and safety data will be presented, following the initial primary overall response results (ORR) that supported the FDA approval for BRAFTOVI + MEKTOVI in this indication in 2023 and the recent approval by the European Commission in August 2024. Further, Pfizer will share updated data from the safety lead-in of the ongoing Phase 3 BREAKWATER trial, showing antitumor activity of BRAFTOVI + cetuximab + FOLFIRI in patients with untreated BRAF V600E-mutant metastatic colorectal cancer (mCRC) in a mini-oral presentation. Additionally, Pfizer will present a late-breaking Proffered Paper Presentation on the Phase 2 efficacy and safety results for its GDF-15 inhibitor, ponsegromab, in patients with cancer-associated cachexia, highlighting the company’s commitment to improving the treatment journey for people living with cancer. Cancer cachexia is a common, life-threatening wasting condition characterized by severe weight loss. The condition affects patients with advanced cancers and can greatly impact a patient’s ability to tolerate cancer treatment and quality of life. Despite its severity, there are no FDA-approved treatments for cachexia. i,ii Pfizer will also present early clinical-stage research for a number of priority pipeline areas, including encouraging Phase 1 results of the potential first-in-class antibody-drug conjugate (ADC) candidate SGN-PDL1V (PF-08046054) in NSCLC and head and neck squamous cell carcinoma (HNSCC); initial data for the investigational ADC disitamab vedotin in combination with KEYTRUDA ® (pembrolizumab) in human epidermal growth factor receptor 2 (HER2)-expressing locally advanced or metastatic urothelial cancer (la/mUC); and the first data combining atirmociclib, our highly-selective cyclin-dependent kinase 4 (CDK4) inhibitor (CDK4i), with a novel CDK2 inhibitor (CDK2i) in hormone receptor-positive (HR+)/HER2-negative metastatic breast cancer (MBC) from a Phase 1 dose-escalation study. Key ESMO Presentations Genitourinary Cancer PADCEV + KEYTRUDA**: additional analysis from the pivotal EV-302 trial continues to support the combination as a new standard of care for patients with previously untreated la/mUC. An exploratory analysis shows PADCEV + KEYTRUDA ® showed consistent progression free survival (PFS), overall survival (OS), and ORR versus chemotherapy regardless of Nectin-4 or PD-L1 expression. Disitamab Vedotin: preliminary efficacy and safety data for disitamab vedotin in combination with KEYTRUDA highlights Pfizer’s continued commitment to developing novel therapeutics to meet the needs of patients with bladder cancer. Results from the safety run-in of the ongoing Phase 2 trial showed encouraging early efficacy and a safety profile consistent with previously presented data in treatment-naive patients with HER2-expressing la/mUC. Thoracic Cancer SGN-PDL1V (PF-08046054): encouraging Phase 1 results will be presented for PDL1V, a novel, investigational vedotin ADC directed to PD-L1-expressing solid tumors. Data from the dose-escalation and dose optimization cohorts of the ongoing Phase 1 study show PDL1V as monotherapy was generally well tolerated with no unexpected adverse events, and encouraging antitumor activity was observed in patients with heavily pretreated NSCLC and HNSCC. Breast Cancer Atirmociclib (PF-07220060) + PF-07104091 : initial data from a dose-escalation study evaluating the innovative combination of atirmociclib, a potential first-in-class CDK4-selective inhibitor, with PF-07104091, a novel CDK2-selective inhibitor, showed a manageable safety profile and encouraging efficacy in patients with heavily pretreated HR+/HER2- breast cancer. These early results highlight the potential of Pfizer's strategy to advance atirmociclib as a future CDK inhibitor backbone therapy that may address treatment resistance with first generation CDK4/6i, subject to clinical success and regulatory approval. The CDK4i+2i combination is continuing to be explored in an ongoing Phase 1b/2 dose escalation and dose expansion study (NCT05262400). Additional information on the Pfizer-sponsored abstracts, including date and time of presentation, follow in the chart below. Pfizer is continuing its commitment to help non-scientists understand the latest findings with the development of abstract plain language summaries (APLS) for company-sponsored research being presented at ESMO, which are written in non-technical language.

Pfizer recently announced that it has completed the acquisition of Seagen, which specializes in antibody drug coupling agents (ADCs), for $43 billion. In talks with investors, the company laid out ambitious plans for its oncology division, aiming to launch eight new cancer drugs by 2020, in addition to its current five best-selling cancer drugs.   Dr. Chris Boshoff, Pfizer's new chief oncology officer, emphasized that the company will focus on four main cancer areas: breast cancer, genitourinary cancers (including prostate and urinary cancers), hematological malignations such as lymphoma and multiple myeloma, and chest tumors such as lung cancer and head and neck cancer.   Pfizer's portfolio will include small molecule therapeutics, ADCs and bispecific antibodies. Biologics are expected to account for 65 percent of oncology revenues by 2030, compared with about 6 percent of sales today, which are dominated by small molecule drugs. Examples include Ibrance (palbociclib) for breast cancer, Xtandi (enzalutamide) for prostate cancer, and Inlyta (axitinib) for kidney cancer.   This business shift helps the company avoid the impact of some of the price cuts in the Inflation Reduction Act (IRA). Under the bill, biologics could be on the market longer before they are selected to participate in Medicare price negotiations.   While the future bestsellers have not yet been disclosed, they will come from the approximately 14 product candidates showcased during the company's R&D update.   "Our oncology group is expected to be a key driver of potential long-term sustainable sales and profit growth for Pfizer through the first half of 2025 and beyond," said Dr. Boshoff.   During the hours-long meeting, Pfizer highlighted seven key Phase 3 trial data and six new Phase 3 trial launches that will underpin its oncology ambitions in the coming years.   These data include the VERITAC-2 trial of the protein depressant vepdegestrant in second-line estrogen receptor-positive metastatic breast cancer, the first key data for a drug that Pfizer believes forms the backbone of estrogen-targeted therapy in breast cancer. And BREAKWATER study of BRAF inhibitor Braftovi (encorafenib) as a first-line treatment for BRAF mutated metastatic colorectal cancer.   Pfizer also has high hopes for the treatment of non-muscle-aggressive bladder cancer with the PD-1/PD-L1 inhibitor Sasizumab in the CREST study, High hopes are also expressed for CD3xBCMA bisspecific Elrexfio (elranatamab) in MagnetisMM-5 as a treatment for relapsed/refractory multiple myeloma patients previously treated with lenalidomide and proteasome inhibitors.   Newly initiated Phase 3 drugs include atirmoiclib, a CDK4 inhibitor for second-line treatment of hormone receptor-positive metastatic breast cancer, IB6-directed ADC sigvotatug vedotin for non-small cell lung cancer (NSCLC), Elrexfio is indicated for patients with multiple myeloma who have progressed after anti-CD38 therapy.   "With the energy of our talented colleagues, the tremendous potential of our product line and scientific engine, and the scale of the Pfizer enterprise, we believe we are well positioned to achieve our vision of accelerating breakthroughs that will help cancer patients around the world live better, longer lives," said Dr. Boshoff.   Pfizer's accelerated push into cancer, which has underpinned its growth over the past few years, comes amid a sharp contraction in the market for COVID-19 vaccines and was one of the drivers behind the Seagen acquisition. Currently, the company spends 40% of its R&D budget on oncology.
