Several Phase 1 clinical trials have evaluated Anle138b in healthy volunteers and patients with Parkinson's disease, with all studies reaching completed recruitment status. Led by industry and academic sponsors—including MODAG GmbH, Aptuit, Quotient Sciences, and Nottingham University Hospitals NHS Trust—these investigations encompass first-in-human safety, tolerability, and pharmacokinetic assessments, CYP1A2 and CYP3A4 drug-drug interaction studies, and multiple ascending dose evaluations. Together, these early-stage studies establish the clinical safety and pharmacokinetic profile of the compound.

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). |
