Ursolic acid has been evaluated across several clinical trials spanning early- to late-stage phases to investigate a range of metabolic, muscular, and oncological conditions, including sarcopenia, prostate cancer, spinal cord injury-associated muscle atrophy, metabolic syndrome X, and primary sclerosing cholangitis. Primarily sponsored by academic and university medical centers—such as Pusan National University Hospital, the University of Miami, and The University of Texas Health Science Center at San Antonio—these trials are currently recorded as completed or withdrawn. Specific investigations focus on assessing muscle function, physical performance, and insulin sensitivity in human subjects.

Mechanism and Biochemical Profile
Appendix RUO and cGMP Quality Standards
| Quality Dimension | RUO (Research Use Only) | cGMP (Current Good Manufacturing Practice) |
|---|---|---|
| Clinical Applicability | Prohibited in human clinical trials or medical diagnostics. | Mandatory for human clinical trials (Phase I–III) and therapies. |
| Regulatory Status | Non-regulated grade; exempt from drug manufacturing laws. | Legally enforced by health authorities (e.g., FDA, EMA, NMPA). |
| Facility Environment | Unclassified analytical or research laboratories. | Validated Cleanrooms (ISO Class 5–8) with continuous monitoring. |
| Quality Control | Basic purity and activity testing. | Rigorous safety release testing (Sterility, Endotoxin, Mycoplasma). |
| Process Validation | Basic equipment calibration; no process validation required. | Full qualification (IQ/OQ/PQ) and complete batch records. |
| Quality Assurance | Vendor self-declared without required formal QMS. | Mandatory QA/QC unit, Change Control, CAPA, and vendor audits. |
| Regulatory Impact | High risk of IND rejection if used as a critical raw material. | Required for IND/NDA filings, supported by Drug Master Files (DMF). |
