Supramolecular Therapies for Regenerative Medicine
Our Mission
To develop regenerative therapeutics that promote healing after traumatic injury and increase human healthspans – the time that people can live productive, fulfilling lives
Our Science
Amphix Bio is developing a transformative therapeutic platform for regenerative medicine using supramolecular chemistry
Supramolecular Chemistry
Encodes interactions between molecules
Activates regenerative signals
Interactions between molecules are encoded to enhance communication with cell receptors
Creates scaffold for tissue growth
Molecules form architecture similar to the natural extracellular environment to direct tissue regeneration
Therapeutic Platform
Peptide Amphiphile Molecule
Supramolecular Therapeutic
Dynamic 3D Scaffold
Bioactive Signal
Activates regenerative pathways
Structural Segment
Encodes interactions between molecules
Molecules form structures which activate cell receptors with higher potency than standard drugs
Supramolecular structures create scaffolds with architecture and mechanics similar to natural biology

Advantages of our technology
Enables effective regeneration of cells and tissues without the manufacturing challenges and safety concerns of approaches like cell therapies
Cell free
Tunable to biological targets
Fully synthetic & chemically defined
Easy to manufacture at scale
Shelf stable
Flexible routes of administration
Our Pipeline
Bone Regeneration Program
Lead application: Spinal fusion surgery
Our off-the-shelf bone graft substitute enables orthopedic surgeons to perform spinal fusion without using donor tissue or recombinant proteins like in current approaches
~0.5 million spinal fusion procedures are performed each year in the US
Treats back pain caused by degenerative disc disease
Current approaches have safety issues that limit their use
Neural Regeneration Program
Lead application: Acute spinal cord injury (SCI)
The Stupp lab has developed an injectable therapy that regenerates damaged tissue in the spinal cord after traumatic injury, to restore lost motor and sensory function
~18 thousand people experience traumatic SCI each year in the US
Restores function and reverses paralysis due to acute SCI
There is currently no approved treatment available
Cartilage Regeneration Program
Lead application: Knee articular cartilage repair
Our cartilage regeneration therapy can be injected during minimally invasive joint procedures to repair lesions caused by traumatic injury or long-term degeneration
~1 million patients undergo knee cartilage procedures each year in the US
Regenerates damaged cartilage, injected during standard surgeries
Current approaches use complex cell therapies or have limited efficacy
