Several clinical trials sponsored by academic institutions—including the Medical University of South Carolina, Cairo University, and a collaboration between the Universidade do Porto and Aveiro University—evaluate the biomedical applications of chitosan across diverse clinical indications. Research includes a terminated Phase 1/2 trial assessing chitosan for advanced glycation endproduct modulation in prostate cancer. Additionally, unphased trials investigated nanochitosan for postoperative pain and apical bone healing, as well as the safety of chitosan as a wine fining agent in individuals with shellfish allergy, both of which currently hold an unknown recruitment status.

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). |
