Targeting the
Impossible

TAREXIS is a biotech company advancing innovative therapeutics through novel target discovery for patients with limited treatment options.

First-in-Class Antibody Therapeutics A Real-World Evidence Driven Platform
Platform

Proprietary Discovery Platforms

Two integrated platforms systematically narrow the field to high-confidence targets and pre-validate their clinical performance before IND-enabling studies begin.

01 Tx-Finder™

Autonomous multi-omics Analytics Engine

  • Auto-prioritize best targets from 10,000+ candidates
  • Multi-omics integration & algorithmic scoring
  • Multi-dimensional: druggability + market attractiveness
  • Surface expression, receptor identity, safety profile

4-Step Candidate Filtering Process

Step 1

Overexpressed protein (DEP)

  • Overexpression (Tier-based selection)

Step 2

Druggability

  • Membrane expression
  • Receptor identity
  • Antigen protein structure

Step 3

Toxicity prediction (Toxicity)

  • Normal-tissue expression
  • Immune-cell expression
Illustration of normal tissue and immune cell screening
Step 4

Market attractiveness (Novelty)

  • Development status
  • Indication-expansion potential
Illustration of antibody development, market opportunity and patient reach around a selected candidate
02 Tx-Verifier™

Patient-Derived Organoid Based Validation Platform

  • PDOs from patient-derived clinical samples
  • Fail-gate strategy: eliminate poor candidates early
  • Responder profiling & classification
  • Patient-derived organoid xenograft (PDOX) model
