Clinical Trials

Numerous clinical trials spanning Phase 1 through Phase 4 evaluate aclidinium bromide, focusing primarily on chronic obstructive pulmonary disease (COPD), chronic obstructive airway disease, smoking, and safety in healthy volunteers through Phase 2 pharmacokinetic and Phase 3 efficacy studies. Conducted by pharmaceutical sponsors such as AstraZeneca and Daewoong Pharmaceutical Co. LTD. alongside academic institutions including the University of Milan, University of Dundee, and Maastricht University Medical Center, most of these trials are completed, while others are listed as withdrawn, terminated, or unknown.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Aclidinium Bromide functions as a potent competitive antagonist that binds human muscarinic acetylcholine receptors M1 through M5 with sub-nanomolar affinity, thereby blocking downstream cholinergic signaling pathways and preventing intracellular calcium accumulation in airway smooth muscle cells. This inhibition leads to sustained relaxation of bronchial smooth muscle and localized bronchodilation, directly counteracting airflow obstruction and hyperinflation in patients with chronic obstructive pulmonary disease.

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.

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).
