ETES^TM Platform: Harnessing Endogenous T-cell Defense Against Tumors

The ETES^TM (Endogenous T-cell Engagement System) platform employs custom-engineered fusion molecules designed to activate endogenous T-cell responses specifically and safely against tumor cells. By leveraging naturally occurring immune signaling mechanisms, ETES^TM enables highly selective tumor targeting, offering significant advancements in immunotherapy efficacy and safety. Alfa Cytology's ETES^TM (Endogenous T-cell Engagement System) Platform precisely engages endogenous T cells through modular fusion molecules, enabling selective and robust immune activation for effective cancer treatment.

What is ETES?

The ETES^TM (Endogenous T-cell Engagement System) molecule consists of three crucial functional domains working synergistically to selectively and robustly activate endogenous T cells upon encountering tumor antigens:

This tripartite structure guarantees ETES^TM maintains physiological T-cell activation and significantly reduces unwanted immune

side-effects, including cytokine release syndrome (CRS).

How ETES^TM Works

ETES^TM leverages the body's natural immune system to target and eliminate tumor cells with precision and safety. The process works as follows:

• Targeting Tumor Cells:

  The ETES^TM molecule binds to tumor-specific antigens on cancer cells through its antigen-binding domain, ensuring that only tumor cells are targeted.

• T-cell Activation:

  The TCR binding domain engages the T-cell receptor (TCR), activating the T-cell via its natural signaling pathways without the need for genetic modification.

• Immune Regulation:

  The co-receptor domain anchors the ETES^TM molecule in the T-cell membrane, modulating T-cell activation based on the presence of tumor antigens—activating the immune response only when necessary.

• Tumor Elimination:

  Upon activation, T-cells release cytotoxic molecules that destroy the cancer cells, while sparing healthy tissue due to the precise targeting of tumor antigens.

Key Features of the ETES^TM Molecule

Physiological Activation

Maintains native TCR signaling pathways, minimizing risks associated with artificial receptor signaling.

Tumor-Specific Targeting

High-affinity antigen-binding domains ensure specificity exclusively toward tumor cells.

Conditional Immune Regulation

Co-receptor domains precisely modulate activation thresholds based on antigen presence, improving therapeutic safety.

Modular Adaptability

ETES^TM modular structure allows rapid optimization and customization for various tumor antigens and therapeutic scenarios.

Workflow of ETES^TM Therapy Development

The process of developing ETES^TM therapy is both systematic and adaptable, ensuring that each step aligns with the specific needs of a given tumor target. From initial antigen profiling to preclinical validation, every stage is meticulously designed to guarantee the highest efficacy and safety standards. Below is an overview of the key steps involved in transforming an ETES^TM platform concept into a viable therapeutic candidate.

Advantages of ETES^TM

ETES^TM offers distinct advantages over traditional therapeutic platforms, providing enhanced specificity, safety, and persistence. These key benefits make ETES^TM an ideal solution for tackling the complex challenges of tumor immunotherapy.

Superior Safety

Conditional T-cell activation strictly dependent on tumor antigen presence, significantly reducing adverse immune reactions such as cytokine release syndrome.

Enhanced Specificity

Precision-engineered antigen-binding domains and natural CD3 signaling limit off-target effects, improving therapeutic accuracy and effectiveness.

Improved Therapeutic Persistence

Native-like signaling ensures enhanced long-term T-cell viability and sustained antitumor efficacy, critical for lasting therapeutic outcomes.

Broad Applications: Redefining the Treatable Landscape

The distinct characteristics of the ETES^TM Platform enable its application to some of oncology's most significant challenges. Its foundational attributes—an enhanced safety profile, improved T-cell fitness and persistence, and a flexible modular design—are directly leveraged to address the complex barriers of solid tumors, the drivers of relapse in hematologic malignancies, and the immunosuppressive nature of immunologically “cold” tumors.
