Clinical Trials

Multiple clinical trials evaluate the therapeutic application of hemin across diverse indications, with a primary focus on acute hepatic, acute intermittent, hereditary coproporphyria, and variegate porphyrias across Phase 1 through Phase 3 studies. Additionally, Phase 1 and Phase 2 trials have investigated hemin in healthy volunteers, post-ERCP acute pancreatitis, and diabetic gastroparesis. Sponsored by academic institutions like the Mayo Clinic and pharmaceutical companies such as Alnylam Pharmaceuticals, these studies encompass completed, active non-recruiting, and terminated recruitment statuses.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Hemin functions as an iron-containing porphyrin and potent inducer of heme oxygenase-1, which acts to replenish cellular heme pools and repress the feedback-inhibited enzyme delta-aminolevulinic acid synthase. This down-regulation prevents the accumulation of neurotoxic porphyrin precursors, offering clinical efficacy in mitigating acute porphyria attacks and attenuation of tissue inflammation in post-ERCP acute pancreatitis.

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).
