What Could Explain Delay for Age-Reversal Clinical Trials?

The data show continued delay to impact drugs reaching patients. Instead of increasing drug approval, the statistics showed a trend of increased numbers of drug on hold. The reason for these delays need to be evaluated, and perhaps to apply new technologies to evaluate the data.
