Injectable slow-release therapy reverses osteoarthritis in animal tests

UC Boulder researchers have developed a slow-release injectable therapy that prompts joint cells to repair cartilage and bone, reversing osteoarthritis in animal models within weeks. They’ve completed the first phase of experiments and are moving to safety/toxicity studies to enable human trials—potentially within 18 months—funded by ARPA-H’s NITRO program, as they pursue options beyond pain management and joint replacement.
