Building off pioneering experience in the design and utilization of TYK2 inhibitors

Interferon (IFN) Driven Amplification Loop Drives Neurodegeneration

Blocking the excessive inflammation that drives degenerative diseases with brain penetrant allosteric TYK2 inhibitors could revolutionize the treatment of neurodegenerative diseases

TYK2 Clinical Validation of Genetic Evidence

TYK2 protective partial loss of function mutant (PLoF) is preventative for autoimmune diseases1

TicTwo has generated analogous proprietary genetic data for Alzheimer’s Disease and Frontotemporal Dementia (FTD)

TYK2 protective partial loss of function reduces the likelihood of development of numerous autoimmune diseases1

The safety and efficacy of this loss of function has been reproduced pharmacologically in psoriasis,2  psoriartic arthritis,3 and systemic lupus erythematosus4

We have collected in vitro and in vivo evidence that supports the genetic observations as well as our scientific hypothesis

We will likewise clinically validate brain penetrant TYK2 inhibitors in neurodegenerative diseases
