HYBRID NEUTROPHILS:
A Novel Universal Myeloid
Platform for Cancer Treatment
Hybrid neutrophils combine tumor-killing with immune activation —unlocking antibodies’ full potential in solid tumors
About
Revolutionary Myeloid Cell Therapy for Treatment-Resistant Solid Tumors
Hybrid Bio is a pioneering biotechnology company developing a first-in-class myeloid cell therapy platform designed to overcome the fundamental limitations of today’s immuno-oncology treatments. By harnessing a rare and powerful immune cell type — Hybrid (APC-like) Neutrophils—we aim to transform resistant solid tumors into curable diseases.
Current antibody therapies and immune checkpoint inhibitors often fail in solid tumors due to immune exclusion, T-cell exhaustion, and a hostile tumor microenvironment. Hybrid Bio addresses these barriers directly by bridging innate and adaptive immunity, enabling both rapid tumor cell killing and durable, tumor-specific immune memory.
Founded by a world-class team of immunologists, cell therapy innovators, and biotech executives, Hybrid Bio is advancing a pipeline led by a first-in-class program in EGFR-positive non-small cell lung cancer (NSCLC), with broad expansion potential across antibody-addressable solid tumors.
Science
Hybrid Neutrophils: A Dual-Function Super-Effector Cell
Originating from groundbreaking research by our Scientific Founder, Prof. Evgeniy Eruslanov (University of Pennsylvania), Hybrid Bio’s platform is built on the discovery of a rare, naturally occurring population of long-lived, antigen-presenting neutrophils found in early-stage solid tumors.
Unlike conventional immune effector cells, Hybrid Neutrophils combine:
-
Potent antibody-dependent tumor cell killing
-
Direct activation of adaptive, tumor-specific immunity
This unique biology enables a dual mechanism of action not achieved by existing cell therapies.
Mechanism of Action
-
Direct Tumor Elimination: High expression of functional Fc receptors enables powerful antibody-dependent cellular cytotoxicity (ADCC) against antibody-opsonized tumor cells.
-
Adaptive Immune Activation: Presentation of tumor-derived antigens via MHC class I and II primes both CD4⁺ and CD8⁺ T cells, generating durable anti-tumor immunity and immune memory.
Key Platform Advantages
-
Dual Mechanism of Action: Simultaneous innate killing and adaptive immune priming
-
Designed for Solid Tumors: Enhanced persistence and functionality within hostile tumor microenvironment
-
Native Antibody Compatibility: Works synergistically with approved and pipeline monoclonal antibodies
-
Repeat Dosing Potential: Unlike many engineered cell therapies
-
No Gene Editing: Proprietary ex vivo differentiation using FDA-approved reagents enables scalable, cost-effective manufacturing
-
Broad Pipeline Potential: Applicable across EGFR⁺ NSCLC, HER2⁺ breastcancer, EGFR⁺ head & neck cancer, EGFR⁺ colorectal cancer, and beyond
Human Biological Validation
Independent clinical and translational studies have identified Hybrid Neutrophils as the most beneficial tumor-associated neutrophil subtype across multiple solid tumors.
Elevated levels of these cells in the tumor microenvironment strongly correlate withimproved patient survival in CRC, NSCLC, STAD, RCC, ovarian, breast, and bladder cancers (Wu et al., Cell, 2024).
Preclinical Validation
-
Complete inhibition of tumor growth in multiple in vitro models with different therapeutic antibodies
-
Significant tumor volume reduction in A549 xenograft models in NSGS mice
-
Robust tumor antigen cross-presentation and tumor-specific T-cell activation in vitro
