TECHNOLOGY

Hydroxyl Dendrimer Therapeutics (HDTs)

Hydroxyl Dendrimer Therapeutics (HDTs) are precisely engineered nanomedicines that selectively target activated inflammatory cells without the need for targeting ligands, reducing off-target toxicity to healthy tissues. By targeting the cells that drive disease progression, HDTs enable a more precise and effective approach to treating disease.

PLATFORM

Building companies from science

One platform, many medicines. Individual therapeutic programs become focused operating companies — multiplying the impact of a single validated engine.

PMED - Platform DiagramPMED - Platform Diagram
01

Validate on the platform

Programs are designed and de-risked on the shared HDT engine — chemistry, targeting and early clinical evidence.
02

Form a Target focused company

Validated programs spin out into dedicated operating companies with specialized teams and aligned capital.
‍
03

Scale with partners

Each company advances its indication with strategic partners while the platform continues generating new programs.
ENGINE

A Highly Reproducible Engine for Precision Medicines

The HDT platform is a highly reproducible engine for developing targeted nanomedicines. Rapidly scalable production, consistent pharmacology, and predictable safety enable one platform to support many medicines across multiple disease areas.

Mission

Transforming the treatment of disease through safe and effective targeted nanomedicines.

Our mission is to transform the treatment of diseases with safe and effective targeted nanomedicines referred to as HDTs (hydroxyl dendrimer therapeutics). HDTs treat inflammation-driven diseases with minimal off-target toxicity. Our clinically validated HDT platform has demonstrated human safety with effective targeting to activated immune cells in inflamed tissues.
