Precision Immunology

Pre-clinical precision
immunology

Tolera Bio is advancing targeted approaches designed to support durable immune balance while preserving healthy immunity.

What We Do

Thoughtful science,
translational execution

Tolera Bio is a pre-clinical precision immunology company focused on advancing targeted strategies intended to support immune tolerance. Our work centers on thoughtful design and translational execution, with the goal of enabling clear decision-making from early research through pre-clinical development.

We build programs with rigorous attention to mechanism, safety, and clinical translatability — prioritizing depth of understanding over speed of activity, and long-term durability over short-term signal.

Antigen-Specific Approach

We pursue strategies designed for precision — targeting immune pathways with specificity intended to minimize off-target effects and support selective immune modulation.

Translational Mindset

Every program is designed with clinical translatability in mind — anchoring research decisions to the path from pre-clinical evidence to potential future study.

Safety by Design

Safety is not an afterthought. Our frameworks integrate mechanistic safety evaluation into program design from the earliest stages of research.

Scalable Development

We build operational and scientific infrastructure to support efficient CRO management, cross-functional execution, and program advancement at each pre-clinical milestone.

Where We Are

Building the foundation
for future clinical readiness

  • Discovery and validation — Identifying and characterizing biological hypotheses through rigorous mechanistic studies and model-based evidence generation.
  • Pre-clinical studies — Conducting structured in vitro and in vivo experiments to build the body of evidence needed to understand safety, activity, and biological plausibility.
  • IND-enabling planning — Evaluating the scientific and operational requirements associated with IND-enabling work as part of long-term program strategy.

Forward-looking statements and any implied timelines reflect current planning and are subject to change based on scientific, regulatory, and operational developments.
