ADCs have transformed the therapeutic landscape of oncology and have the potential to shift the treatment paradigm for immune and inflammatory (I&I) diseases by enabling the targeted delivery of payloads to disease-driving immune or inflammatory cells. Hummingbird Bioscience's platform & technologies engineers next-generation ADCs that have the promise to address key limitations of current I&I therapies for patients, including: efficacy ceiling, durability, and tolerability.

AMDC (Antibody Mimetics Drug Conjugate) is a novel multi-component therapeutic platform developed by our research group that utilizes the extremely high-affinity non-covalent interaction between genetically modified, low-immunogenic streptavidin and a bis-iminobiotin payload. With this system, a target-binding protein module-comprising a fusion of low-immunogenic streptavidin and an antibody mimetic-can be rapidly assembled simply by mixing it with a bis-iminobiotin-conjugated payload module, enabling the flexible construction of multifunctional therapeutics. The AMDC platform has already achieved proof of concept (POC) in multiple therapeutic modalities, including radionuclide therapy and photoactivated therapy.
　　In this presentation, we will discuss the development of an AMDC formulation named “Duo-HER2” that targets HER2-positive solid tumors. Duo-HER2 consists of a HER2-targeting VHH mimetic fused to low-immunogenic streptavidin and a bis-iminobiotin payload conjugated to duocarmycin, a highly potent DNA-alkylating cytotoxic agent capable of inducing cancer cell death at extremely low concentrations. Our research aims to establish practical development strategies for next-generation multifunctional biopharmaceuticals and to accelerate the clinical application of AMDC therapeutics for advanced cancer, a condition with extremely high unmet medical needs.

• Leveraging new delivery mechanics: e.g. receptor-mediated transport for next-gen antibody therapeutics

• Targeting neuroinflammation via the blood-brain barrier for Alzheimer’s and neurodegenerative disorders.

Antibody-based biologics continue to broaden the therapeutic landscape, and tailoring of effector functions and plasma half-life is a commercially competitive differentiator. In humans, the plasma half-life of most IgG antibodies but also albumin is about 3 weeks at average. This has made IgG the natural choice for design of antibody formats, while albumin is increasingly used as a fusion partner for a range of therapeutic modalities. Remarkably, the plasma half-life of these unrelated proteins is prolonged by a common cellular Fc receptor, FcRn. In addition, Fc engineering for enhanced or silenced effector functions is the key to secure potent and specific mode of actions, which must be carefully controlled on a case-to-case basis dependent on the context. In this talk, I will elaborate on how in-depth insights into the complex structural and cellular mechanisms that govern the functions of FcRn can pave the way for design of antibody and albumin based formats with improved binding and transport properties. This perspective will further be discussed in light of engineering for specific engagement of Fc receptors and the complement system.

• Costimulatory target selection: considerations around disease indication, tumor antigen, antibody format, and clinical strategy
• Engager optimization via sequence-based discovery paired with functional and developability assessments across mono- and bispecific formats
• Preclinical development of RNDO-564, a CD28 × Nectin-4 bispecific antibody in a Phase I clinical trial for Nectin-4-expressing solid tumors

The development of effective anti-fibrotic biotherapeutics is limited by a lack of human-relevant analytical frameworks linking immune modulation to functional tissue outcomes. Here, we present an immune-competent, human iPSC-based analytical platform that quantitatively resolves macrophage-fibroblast crosstalk in cardiac fibrosis. By integrating high-resolution spectral flow cytometry with functional co-culture and conditioned media assays, we define macrophage phenotypic states and directly map these states to cardiac fibroblast activation and extracellular matrix responses. This platform enables mechanism-linked potency and differentiation assessment of macrophage-targeting antibodies, supporting target validation, candidate ranking, and potency assessment for next-generation anti-fibrotic biologics.
