Clinical Trials

Multiple clinical trials are currently evaluating therapeutic approaches for conditions linked to sorbitol metabolism and neurodegenerative pathways, including Charcot-Marie-Tooth disease, phosphomannomutase 2 deficiency, and hereditary neuropathy caused by SORD deficiency. Representing Phase 2, Phase 3, and combined Phase 2/Phase 3 protocols, these studies are sponsored by academic and industry entities such as The Third Xiangya Hospital of Central South University, Maggie's Pearl LLC, and Applied Therapeutics Inc. Featuring recruitment statuses ranging from active, not recruiting to not yet recruiting, the trials aim to assess safety, pharmacodynamics, and clinical efficacy in affected patient populations.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Sorbitol serves as an intracellular sugar alcohol substrate within the polyol metabolic pathway, where its accumulation drives hyperosmotic stress, liquid retention, and cellular dysfunction in neural and lens tissues. This osmotic and biochemical stress promotes tissue damage and cellular degeneration, providing direct mechanistic relevance to metabolic peripheral neuropathies including Charcot-Marie-Tooth disease and hereditary neuropathy caused by sorbitol dehydrogenase deficiency.

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).
