2 Introduction This research is intended to indicate appropriate guidance for technology transfer expected to increase under the new manufacturing and marketing approval system to be implemented by the revised Japanese Pharmaceutical Affairs Law, and supplement the GMP regulations to be revised soon. The research is also intended to propose some regulations to realize technology transfer necessary for high quality and stable manufacturing of developed products and existing products by reviewing technology transfer based on the following ideas. The technology transfer means actions to transfer information and technologies necessary to realize quality of design of drugs during manufacturing. Appropriate technology transfer is important to upgrade the quality of design to be the quality of product, and ensure stable and high quality of the product. It should be noted that drugs may influence human lives and health, and their raw materials, compositions and manufacturing methods are changed during their long term manufacturing and marketing. To assure the drug quality, it is desired to make sure 5 W s and 1 H, that is what, when and why information should be transferred to where and by whom and how to transfer, then share knowledge and information of the drug product between transferring and transferred parties. The technology transfer does not mean one time actions taken by the transferring party toward the transferred party, but means continuous information exchange between the both parties to maintain the product manufacturing. Basic Policies on the Establishment of the Guideline for the Technology Transfer The basic policies on the establishment of this guideline are shown as follows. 1) Assurance of consistency through development and manufacturing To make developed product have indications as assumed in clinical phases, the quality of design should be reproducible as the quality of product. The transferring party in charge of development should fully understand what kind of technical information is required for the technology transfer, and should establish an appropriate evaluation method to determine whether a drug to be manufactured meets the quality of design. It should be fully recognized that technical information of developed product are generated from data of a limited amount of batches, various standards have been established from the limited data, and quality evaluation method established in development phase is not always sufficient for factory production. Information of similar products of the past should be fully referred as well. 2) Embodiment of Quality by Specifications It is desired to verify that the specification adequately specifies the product properties and quality. The product specification should ensure that the quality assumed in the quality design is assured as the manufacturing quality, and the product satisfies the quality of design. It should be fully understood that manufacturing quality is based on the product specification. Relations between control limits of manufacturing formula (compositions and manufacturing methods) and limits of the product specification should be fully understood, and appropriate specifications and the control range should 2

3 be established to maintain the consistency between the manufacturing quality and product specification. For specifications of raw materials, components, intermediates, and in process testing, consistency between test items, specification range, and product specifications should be maintained. Since initial manufacturing formula and specification are established based on limited information, the consistency between the quality and specification after the start of manufacturing should be fully verified, and these should be revised through appropriate change controls, if necessary. 3) Documentation Management and Update of Technical Information Responsibility system should be established in view of accountability (responsibility for giving sufficient information) and responsibility (responsibility for consequences of actions). For that purpose, appropriate documentation management of technology transfer ishighly desired. For drugs as they have long product shelf life, the documentation management should be performed assuming that the technology transfer would occur several decades after the completion of development. Initial manufacturing quality is established based on limited information. As a result, it may be necessary to propose revised technical information at regular intervals as additional information of the product quality is gained and accumulated with improvements or revisions of specifications and test methods. Table of Contents The table of contents is shown as follows. The 1st chapter addresses background and the scope of the guideline. The 2nd chapter addresses handling and contents of technologies to be transferred at each process from research and development to manufacturing. The remaining chapters address procedures, documentation, and points of concern with regard to facilities, test methods, drug substances, and drug products all of which are closely involved with drug manufacturing. 1.
