Functional Immune Cell–Cell Interaction Platform

Decoding the T-cell “dimmer switch” controlling clonal expansion

Bionoxx is a clinical-stage immuno-oncology company developing OTS-412/HU, an oncolytic virotherapy designed to restore productive anti-tumor T-cell responses through host immune modulation. The program is currently being evaluated under regulatory-approved clinical studies in the United States and Korea.

To enable mechanism-driven immune modulation, we developed BNX-IFS™ (Bionoxx Immune Functional Interaction System), a proprietary platform that quantitatively decodes functional immune cell–cell interaction states centered on activated T cells.

BNX-IFS™ is currently being applied and validated within the OTS-412/HU clinical program, where it is used to monitor functional immune remodeling and guide strategies for restoring productive anti-tumor T-cell responses.

Through this clinical application, Bionoxx identified a novel biological mechanism in which activated T cell–centered immune cell–cell interaction states regulate post-activation T-cell expansion and anti-tumor immunity.

Importantly, BNX-IFS™ enables rapid functional immune validation in early clinical studies, supporting data-driven next-stage trial design not only in immuno-oncology but also across a broad range of immune-related diseases. This capability enables early qualification of therapeutic candidates and establishes a structured pathway for partner asset evaluation prior to strategic collaboration.

SCIENTIFIC PLATFORM

Functional immune interaction decoding platform

BNX-IFS™ is a functional immune analysis platform that quantitatively detects and interprets cell-cell interaction states centered on activated T cells.

Beyond conventional static immune phenotyping, this platform introduces a new analytical framework in which functional interaction states between immune cells themselves become the primary unit of analysis.

  • Functional immune signal detection
  • Cell-cell interaction mapping
  • Biomarker discovery and patient stratification
  • Mechanism-of-action clarification
  • Immune modulation guidance

Biology

BIOLOGICAL FOUNDATION

Functional immune regulation beyond the tumor microenvironment

The success of cancer immunotherapy is determined not only by the tumor microenvironment but also by the host immune condition. In particular, immune regulation acting after TCR activation can determine whether productive T-cell expansion is sustained and whether anti-tumor immunity is maintained or suppressed.

Bionoxx identified a regulatory mechanism in which neutrophils modulate post-activation T-cell responses through multi-layer cell-cell interactions, and demonstrated that this biology can be quantitatively analyzed using BNX-IFS™.

This biology provides the foundation for a new therapeutic strategy to restore anti-tumor T-cell activity and overcome resistance to immune checkpoint inhibitors.

TRANSLATIONAL APPLICATION

Platform-driven host immune modulation

BNX-IFS™ functions not only as an analytical platform but also as a translational engine.

It enables functional immune-state assessment, prediction of therapeutic response, design of immune modulation strategies, and discovery of clinical biomarkers.

This approach is being applied to OTS-412/HU-based oncolytic virotherapy to rebalance host immune regulation and restore productive T-cell–dominant anti-tumor immunity.

Clinical

CLINICAL PROGRAM

Platform-guided clinical development

Bionoxx is advancing clinical-stage programs under regulatory approval in the United States and Korea. These studies are designed not only for safety evaluation but also to define immune signals based on functional immune interactions.

BNX-IFS™ is being used to quantitatively assess immune reprogramming signals, restoration of T-cell responses, and host immune modulation dynamics in clinical samples.

Collaboration

COLLABORATION

BNX-IFS™–Guided Asset Qualification for Strategic Partnership

Bionoxx provides a BNX-IFS™-guided pre-partnering validation program to evaluate partner assets within a functional immune interaction framework.

Partner candidates are assessed for their ability to modulate host immune interaction states associated with productive T-cell responses.

  • Early identification of immune-active assets
  • Functional biomarker discovery
  • Mechanism-of-action clarification
  • Patient selection strategy development
  • Translational validation prior to partnership

The resulting data package supports go/no-go decisions and structured progression toward strategic collaboration or co-development agreements.
