Clinical Trials

Several Phase IV clinical trials evaluate sulbactam for bacterial conditions, specifically focusing on pneumonia, ventilator-associated pneumonia, and Acinetobacter infections. Sponsored by academic institutions and pharmaceutical companies—including Prince of Songkla University, Hospital Pablo Tobón Uribe, and Pfizer—these investigations examine pharmacodynamic dosing models and combination intravenous therapies. Across this research portfolio, recruitment statuses include both completed and withdrawn studies.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Sulbactam binds to and inhibits bacterial beta-lactamase enzymes with an average IC50 of 0.8 μM, thereby preventing the enzymatic hydrolysis of co-administered beta-lactam antibiotics. This protective activity restores bacterial susceptibility to antimicrobial treatment, providing therapeutic relevance in clinical trial conditions including pneumonia, ventilator-associated pneumonia, and Acinetobacter infections.

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).
