Pregenerate, Inc. provides products and services to replace expensive and inefficient animal testing in medical and pharmaceutical research. Currently Pregenerate Inc. is focusing on global degenerative joint disease, osteoarthritis, which not only affects the aging human population but also sport horses and our beloved companion animals. We use scaleable organ-on-a-chip models to replace animal testing in pharmaceutical research for arthritis treatments. This enables pharmaceutical companies to save billions of dollars and improve the success rates of their drugs to market, in part because we can use human cells in our model. Ultimately, this same technology will allow us to stratify patients into targeted treatment subgroups, and even to tell each clinical patient what the best treatment is for his or her specific arthritis needs directly.
