Technology Transfer

Technology transfer moves a product and — more importantly — the knowledge behind it, either from development into commercial manufacture or between manufacturing sites. ICH Q10 names it as a distinct lifecycle stage precisely because it is where knowledge is most often lost: the receiving unit inherits a procedure without the reasoning, the failed experiments, or the understanding of which parameters actually matter.

The mechanics are a sending unit and a receiving unit working to a written transfer protocol: what is being transferred, the acceptance criteria that will demonstrate success, the analytical methods and their co-validation, the process parameters and their proven ranges, the equipment differences and how they will be bridged, and the training required. Gap analysis between the two sites — equipment train, scale, utilities, materials, and analytical capability — is where the real risk is found.

Success is demonstrated, not declared. The receiving site typically runs engineering or demonstration batches, then process performance qualification, against criteria agreed in advance. Analytical method transfer runs in parallel and is frequently underestimated — a method that performs differently on the receiving site’s instruments will make an otherwise successful process transfer look like a failure.

• —Transfers knowledge, not just documents — the reasoning behind the process is the asset.
• —A written protocol defines scope, acceptance criteria, methods, parameters, and training.
• —Gap analysis of equipment, scale, utilities, materials, and analytical capability drives the risk.
• —Analytical method transfer runs in parallel and is routinely underestimated.
• —Success is proven with demonstration batches and PPQ against pre-agreed criteria.
• —For biologics, a site change usually triggers a formal comparability exercise.

ICH Q10 §3.1.2 (Technology Transfer as a lifecycle stage); ICH Q8(R2) and Q11 for the development knowledge transferred; WHO TRS 961 Annex 7 (WHO guidelines on transfer of technology in pharmaceutical manufacturing); EU GMP Chapter 7 where activities are outsourced.
