A new treatment that blocks an aging-related protein restored lost cartilage in old mice and helped prevent arthritis after knee injuries. Human cartilage samples showed similar signs of regeneration, raising hopes for a future drug that could repair joints instead of replacing them.
This drug has already gone through Phase 1 human trials for a separate condition.
Phase 1 trials only test safety in healthy adults, but this drug passed. (Still awaiting the paper on the trial)
The delivery method was a once a day pill.
