Quality Management
Sinopep is fully committed to providing the highest quality products and services. The Sinopep "Quality Manual" is established based not only on the requirements of regulatory agencies such as NMPA, US FDA, EMA, ICH, and regulatory guidelines such as 21 CFR Part 210/211/820 and ICH Q7/Q8/Q9/Q10, but also on Sinopep's top management's strong commitment to ensuring our operation and control of processes in CMC (Chemistry, Manufacturing and Controls) are conducted in full compliance meeting the highest level of global quality requirements.
Sinopep’s Quality System spans the entire product lifecycle, encompassing all phases of clinical development, commercial launch, and post-launch activities.
- Quality System
- Laboratory Control System
- Material Management System
- Production Management
- Facility & Equipment Management
- Packaging & Labeling System
These elements are effectively implemented across all stages of the product lifecycle, with consideration given to the specific objectives and requirements of each phase. Opportunities for quality improvement and efficiency enhancement through innovative solutions are carefully assessed and introduced at appropriate timepoints, ensuring full regulatory compliance.
Established based on ICHQ7 requirements
Quality Systems: Four Layers of Support
Sophisticated Quality Control Document System
| Quality System Area | What It Covers |
|---|---|
| Master Documents / Quality Manual / SOPs | Documentation hierarchy governing all GMP operations |
| Raw Material & Finished Product Release | Testing and release criteria ensuring every batch meets specification before use or shipment |
| Equipment Calibration & Qualification | IQ/OQ/PQ protocols and routine calibration to maintain validated, audit-ready equipment |
| Change Control | Structured review and approval process for any change affecting product quality or compliance |
| Deviation / OOS Investigation | Root cause investigation and resolution for any deviation or out-of-specification result |
| Product Quality Review | Periodic trend analysis confirming consistent process performance and product quality |
| CAPA Management | CAPA management — corrective and preventive action system closing the loop on quality issues |
| Training Programs | Documented, role-based training ensuring staff competency on GMP procedures |
