In the project initiation phase, the focus is on establishing the framework and coordination mechanisms:

Establish a Multidisciplinary Team: Form a professional team comprising members from Quality Assurance (QA), Quality Control (QC), Manufacturing, Engineering, and Project Management departments.

Sign a Quality Agreement: Clearly define the legal and economic responsibilities of both parties (Sending Unit and Receiving Unit) concerning data management, validation, and regulatory filings.

Product Information Transfer: Includes the Target Product Profile (TPP), Critical Quality Attributes (CQAs), and Critical Process Parameters (CPPs).

Raw Material Information: Provide specifications for the Active Pharmaceutical Ingredient (API) and excipients, supplier information, stability data, and Material Safety Data Sheets (MSDS).

Process Description Documents: Transfer Process Flow Diagrams (PFDs), Bills of Materials (BOMs), Master Batch Records (MBRs), and detailed production operating instructions.

Facility and Utilities: Assess whether the Receiving Unit's HVAC, water systems, and gas systems meet process requirements.

Facility and Equipment Comparison: Compare the working principles, materials of construction, and models of equipment between the Sending Unit and the Receiving Unit to identify differences in capacity and functionality.

Process Adaptation: Make necessary process adjustments based on equipment or material supply constraints, or implement modifications/acquisition of new equipment.

Analytical Method Transfer: Prior to process validation, ensure the Receiving Unit can accurately execute the analytical methods for testing the drug product, raw materials, and cleaning residuals.

Process Transfer/Reproduction: Before formal GMP manufacturing, run engineering/scale-up batches to adjust parameters and mitigate initial production risks.

The final phase of the project focuses on result confirmation and ongoing monitoring:

Comparability Studies: If the transfer occurs during the clinical stage or after a commercial change, demonstrate that the product manufactured post-transfer is comparable in quality and safety to the product manufactured previously.

Regulatory Filings: Prepare and submit required regulatory change applications or the CMC sections of marketing authorization dossiers.

Technology Transfer Report: Compile all data, deviation handling, and conclusions to demonstrate that the Receiving Unit is capable of routinely manufacturing the product.
