Our Quality Management System (QMS) ensures that all of our GMP manufacturing activities comply with global regulations. This includes regulations from the FDA, EMA and CFDA in raw material and supplier control, manufacturing control, data integrity and control, GLP and GDP, etc.
Our GMP facilities, equipment and personnel are closely governed, monitored, and documented, to ensure that we can provide the best support to our clients throughout all stages of development and commercial production.
Our carefully constructed core QMS governing structure consists of a quality manual, quality policy, SOPs and records, forms, protocols and reports.
The quality manual is the highest-level document in Porton Advanced’s quality system. It governs the rest of the levels of quality document. In the case of a conflict, the quality manual prevails unless otherwise stated. The quality policy describes the management strategy for different aspects of the QMS, derived from the quality manual. All standard operating and management procedures, quality specifications, process procedures or job descriptions are included in the documents that guide operations. Finally, records, protocols, forms and reports are the cornerstone of our quality system and are used to demonstrate that the quality system is in good operation.
The QMS regulates all our operations and should be applied as appropriate to all projects and products at all stages.
Through years of operating as a CDMO, we have established a robust quality management system, with collective experiences in numerous key areas:
Our technology transfer activities include both technology and knowledge transfer of the product, manufacturing process or analytical methods from throughout R&D and manufacturing stages.
The methods can be transferred between different manufacturing facilities, as well as from clients external to Porton Advanced.
We have established robust technology transfer procedures (SOP-SZCC-0047; SOP-SZQC-0048), built on planned, controlled transfer activities, which enable us to obtain products and analytical methods that meet the requirements of our clients.
Our robust procurement process clearly defines the procurement of materials and related services required for development and manufacturing operation activities. This ensures that the purchased materials or services are of high quality, are traceable, and that suppliers can provide reliable and accurate input and value-added services.
Our import and export processes (CL-SZPP-0001; CL-SZPP-0002) ensure that our import and export activities are compliant, smooth, and ensure the timely delivery of special goods, including microorganisms, human tissues, biological products, blood and its products, and biological materials of animal resource.
The established procedure also defines the documents required for customs inspection and related processes.
Our registration team have many years of global regulatory experience, such as with ICH, FDA and EU registrations. We also have established eCTD templates for IND and BLA registration.

AAV variants enriched in different tissues during library screening. AAV libraries were prepared and injected into the hosts. After two weeks, tissues were harvested and viral genomes were isolated for PacBio sequencing. Viral genomes were clustered against different tissues.

Time course of CAR transduction rates of CD3 T cells and cell viability during manufacturing in two cases. T-cells transduced with lentivirus analyzed by flow cytometry to detect CAR-positive or Protein L-positive cell ratio. T-cells expressed CAR stably in the period of CAR-T cell growth with high cell viability.
