NEW YORK--(
BUSINESS WIRE
)--Pfizer Inc. (NYSE: PFE)
will highlight the latest advancements from its growing hematology and breast cancer portfolios at the American Society of Hematology (ASH) Annual Meeting & Exposition (December 7-10) and the San Antonio Breast Cancer Symposium (SABCS, December 10-13). Data from more than 100 company-sponsored, investigator-sponsored, and collaborative research abstracts, including 13 oral presentations and four poster spotlights, will be shared across the company’s approved medicines and expanding portfolio of potential breakthroughs for patients with blood and breast cancers, as well as rare blood disorders.
“
Our robust presence at ASH and SABCS reinforces Pfizer’s legacy of scientific innovation for people living with blood disorders and breast cancer,” said Chris Boshoff, Chief Oncology Officer and Executive Vice President, Pfizer. “
We are pleased to share the latest updates for some of our key approved medicines, including ADCETRIS, ELREXFIO, and IBRANCE, which continue to generate compelling data as foundations of care in their respective indications. We are also excited to present new results in hemophilia and from our expanding pipeline of innovative, next-generation therapy candidates for both blood and breast cancers, including new data on combination approaches across our core scientific modalities.”
Key ASH Presentations
Data from more than 75 company-sponsored, investigator-sponsored, and collaborative research abstracts will be presented at ASH, including updated analyses from the pivotal ECHELON-3 trial supporting the clinical benefit of ADCETRIS
®
(brentuximab vedotin) in patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL). New data for ELREXFIO
®
(elranatamab-bcmm) in relapsed/refractory multiple myeloma (RRMM) will also be presented from the pivotal MagnetisMM-3 trial, as well as Phase 1 combination data from the MagnetisMM-20 trial. Pfizer will also present updates from its growing Hematology-Oncology pipeline, which includes next-generation CD30 antibody-drug conjugates and other novel and differentiated molecules, including the first presentation of combination data for SEA-CD70 in high-risk myelodysplastic syndromes.
Additionally, Pfizer will present results across its portfolio of investigational and approved medicines in benign hematology.
ADCETRIS:
Additional analyses from the Phase 3 ECHELON-3 trial will be presented, highlighting the durability of complete responses and consistent benefit of ADCETRIS in combination with lenalidomide and rituximab in patients with relapsed/refractory DLBCL, including enrollment of elderly patients, those who are refractory to most recent treatment, and those who have received prior CAR-T therapy. These findings also underscore the overall survival (OS) advantage over lenalidomide and rituximab plus placebo in patients who have received at least two prior lines of therapy. In addition, updated two-year follow-up data from a Phase 2 study investigating the combination of ADCETRIS, nivolumab, doxorubicin, and dacarbazine in newly diagnosed early-stage classical Hodgkin lymphoma (cHL) will be presented highlighting promising efficacy and safety of this investigational novel combination.
ELREXFIO:
A post hoc analysis of the Phase 2 MagnetisMM-3 trial continues to show deep and durable responses after longer-term follow-up of nearly three years, and these responses were also maintained with a reduction to once-monthly dosing in RRMM. Data will also be shared from the ongoing Phase 1b MagnetisMM-20 trial that indicate encouraging clinical efficacy and predictable safety signals with ELREXFIO in combination with carfilzomib and dexamethasone after a median of two prior lines of therapy (range: one to three).
SEA-CD70 (PF-08046040):
Encouraging preliminary data from the ongoing Phase 1 study with PF-08046040, also known as SEA-CD70, a nonfucosylated monoclonal antibody targeting CD70 that is designed to enhance effector function, will be shared for the first time from the combination dose-optimization cohort with azacitidine in patients with higher-risk myelodysplastic syndromes (MDS). SEA-CD70 is being developed with the goal of being a best-in-class foundational medicine either alone or as combination treatment in myeloid malignancies.
Key SABCS Presentations
Data from 30 company-sponsored, investigator-sponsored, and collaborative research abstracts will be presented at SABCS, including nine real-world analyses affirming IBRANCE
®
(palbociclib) as a first-line standard-of-care treatment for hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) metastatic breast cancer (MBC). The company will also present new data from its expanding pipeline of innovative, next-generation therapy candidates that have the potential to address critical unmet patient needs across all subtypes and stages of breast cancer, including new and updated Phase 1 data for atirmociclib, vepdegestrant, and the novel KAT6 inhibitor, PF-07248144.
IBRANCE
:
In P-VERIFY, the largest-ever real-world comparative overall survival analysis of first-line CDK4/6 inhibitors plus aromatase inhibitor (AI) therapy in HR+/HER2- MBC, numerically similar overall survival rates were observed across CDK4/6 inhibitor groups at 12, 24, and 30 months.
Atirmociclib (PF-07220060):
Updated data will be presented from a Phase 1/2a study of atirmociclib, a next-generation, highly selective CDK4 inhibitor, in combination with letrozole as a potential first-line treatment for patients with HR+/HER2- MBC. Atirmociclib is being developed as a potential future CDK inhibitor backbone therapy in HR+ MBC, and a Phase 3 study in the first-line setting is anticipated to start by early 2025.
Vepdegestrant:
For the first time, initial Phase 1b data will be shared from the Phase 1b/2 TACTIVE-U trial evaluating the combination of vepdegestrant, a potential first-in-class PROteolysis TArgeting Chimera (PROTAC) estrogen receptor (ER) degrader, in combination with abemaciclib in patients with ER+/HER2- locally advanced or MBC. These data reinforce the potential of vepdegestrant as a new backbone endocrine therapy, and Pfizer and Arvinas anticipate topline Phase 3 data evaluating vepdegestrant as a monotherapy in the first quarter of 2025.
KAT6 (PF-07248144)
: Updated efficacy and safety data will be presented from a Phase 1 dose-expansion study of PF-07248144, a novel KAT6 inhibitor, in heavily pretreated ER+/HER2- MBC. These early data continue to provide strong clinical proof of concept for this novel target as a potential new treatment approach for ER+/HER2- MBC, and Pfizer anticipates initiating a Phase 3 study for PF-07248144 in the post-CDK4/6 inhibitor setting in mid-2025.
