MECHANISM-BASED RARE DISEASE COLLABORATION

Working together to unlock the potential of ROCK inhibitors for rare genetic disorders.

Rare genetic disorders are often developed one gene at a time, even when several disorders converge on the same druggable pathway. ROCK Access Collaborative, an initiative of OPHN1 Foundation, brings together rare-disease organizations, researchers, clinicians, and other stakeholders to evaluate which disorders involve therapeutically relevant RhoA–ROCK dysregulation and where shared scientific, safety, biomarker, and regulatory infrastructure can accelerate responsible therapeutic development.

This diagram is intentionally simplified. Whether ROCK inhibition is appropriate depends on the direction, strength, and biological context of pathway dysregulation in each disorder.

CURRENT WORK

Building shared infrastructure for ROCK-focused rare disease research

Evaluate pathway evidence

Develop a mechanism-based framework for assessing whether RhoA–ROCK dysregulation is therapeutically relevant in individual rare genetic disorders.

Identify shared research needs

Define opportunities to share translational evidence, pediatric safety and pharmacology considerations, biomarkers, assays, and research standards across disease communities.

Develop responsible pathways

Examine regulatory, clinical research, data, and access frameworks that may support careful evaluation of ROCK-targeted therapies.

WHY COLLABORATE?

One pathway. Shared infrastructure. Greater leverage.

Shared biology

Identify disorders with evidence of therapeutically relevant RhoA–ROCK dysregulation.

Stronger science

Pool expertise, disease models, assays, and data while reducing duplication.

Better safety path

Build shared pediatric safety, pharmacology, and biomarker strategies.

Regulatory efficiency

Explore common protocols, data standards, and responsible access pathways.

Greater impact

Give small organizations a stronger collective voice with researchers, funders, and industry.

OUR APPROACH

From pathway hypothesis to responsible development

1

Identify disorders

Assess gene function, pathway direction, and disease-specific rationale.

2

Generate evidence

Prioritize models, target-engagement assays, and translational biomarkers.

3

Build shared infrastructure

Develop reusable safety, outcomes, data, and governance frameworks.

4

Pursue access and trials

Evaluate expanded access, early-phase studies, and other regulatory routes.

5

Improve lives

Accelerate careful testing of treatments for the people most likely to benefit.
