WHO Guidelines For Technology Transfer (TT)
Table of Contents
what is a technology transfer?
Technology transfer (TT) is a structural guideline that is intended for the quality of the process, products, standardization, and cost-effective productions.
This is a systematic process in which knowledge and experience are gathered and documented during the life cycle of products originated from development, manufacturing, production, and marketing or commercialization and are transferred to an authorized and accountable organization. Technology Transfer is a fundamental part of the discovery and development of newer pharmaceutical products and dosage forms.
As per World Health Organization, technology transfer is defined as, “A logical procedure that controls the transfer of any process together with its documentation and professional expertise between development and manufacture or between manufacture sites.”
In the Pharmaceutical industry, Technology Transfer is involved in drug discovery, product development, clinical trials, and full-scale commercialization.
Different Terminology Of Technology Transfer (TT)
1.Active Pharmaceutical Ingredients (API): Any ingredients or substances which are used in the manufacturing of a pharmaceutical formulation and are considered as active ingredient of that dosage forms, are called as Active Pharmaceutical Ingredients (API).
2. Change Control (CC): Change control can be defined as, “A formal system by which qualified representatives of appropriate disciplines review proposed or actual changes that might affect the validated status of facilities, systems, equipment or processes. The intent is to determine the need for action that would ensure and document that the system is maintained in a validated state.” (EU GMP Guidelines, Annexure 15).
3. Control Strategy: The proper sets of control obtained from product and process understanding to assure the process performance and product quality which include parameters of products, materials, drug substances, facilities, equipment availability, standardization process, in-process control, quality of finished goods, etc.
4. Critical Control Point (CCP): Some controls are mandatory in the pharmaceutical industry to eliminate or to reduce the quality hazards. CCP is a step at which this control can be applied.
5. Corrective Actions (CA): Corrective actions are taken at CCP while controlling the quality hazards.
6. Quality Assurance (QA): According to WHO “Quality Assurance” is a wide-ranging concept covering all matters that individually or collectively influence the quality of a product. It is the totality of the arrangements made with the object of ensuring that pharmaceutical products are of the quality required for their intended use. Quality assurance, therefore, incorporates GMP and other factors, including those outside the scope of this guide such as product design and development.
7. Quality Control (QC): QC is that part of GMP concerned with sampling, specification, testing, documentation, and release procedures which ensure that the necessary and relevant tests are performed, and the product is released for use only after ascertaining its quality.
8. Design Qualification (DQ): DQ is a documented verification of the proposed design of the facilities, systems, and equipment that are suitable for the intended purpose.
9. Installation Qualification (IQ): IQ is evidence of all key aspects of the process equipment and ancillary system installation adhere to the manufacturer’s approved specification.
10. Operational Qualification (OQ): OQ is established by an objective evidence process for the control limits and action levels in the product of all predetermined requirements.
11. Performance Qualification (PQ): PQ is established by verifying a process, under anticipated conditions, consistently produces a product that meets all predetermined requirements.
12. Drug Master File (DMF): It is detailed information of a specific facility, process, or product that has been submitted to the Medicines Regulatory Authority (MRA) for the incorporation into the application for the marketing authorization.
13. Finished Pharmaceutical Product (FPP): A finished pharmaceutical product will be considered as a product that contains one or more APIs and has undergone all steps of production, standardization, packaging, storing, and labeling.
14. Technology Transfer: Inter-Company Transfer: The transfer of technology between sites of different companies is called intercompany transfer.
15. Technology Transfer: Intra-Company Transfer: The transfer of technology between sites of the same group of companies is called intracompany transfer.
16. Standard Operating Procedure (SOP): It is an authorized written procedure with detailed instructions for the operation of equipment, maintenance of equipment, cleaning of equipment, validation of equipment, environmental control, sampling, and analytical procedures.
17. Technology Transfer Report (TTR): A documented report of technology transfer consists of:
- Acceptance criteria
- Obtained results
- Deviations, if any
18. Sending Unit (SU) and Receiving Unit (RU): The discipline of any organization involved in transferring of designated process or method is called a sending unit (SU) and the organization involved in receiving the same is mentioned as receiving unit (RU).
General Principles of Technology Transfer (TT)
The basic requirements of Technology Transfer are:
- Quality Risk Management (QRM)
- Documented approach
- Logical approach
- Skilled and trained staff
- Sending Unit (SU)
- Receiving Unit (RU)
The following general principles are to be followed for the successful Technology Transfer:
- The project should attain the quality parameters based on QRM.
- The facilities and equipment available in SU and RU should be similar.
- The trained and skilled staff should be available at RU.
- RU should reproduce the documented evidence of transferred product, process, or manufacturing method against the predetermined specifications of SU.
- Reporting of specifications results and errors by the RU to SU.
- The clarity of the transfer process should be maintained.
- The legal implications like royalties, intellectual property rights, conflict of interests should be conveyed before and during the transfer.
Technology Transfer Protocols
The transfer process should be managed by SU, RU and if required, an additional agency in which proper directions and approvals are provided. There should be a proper management plan and formal agreements for the successful technology transfer.
The following steps should be followed as per the transfer protocol.
- Purpose and objective of the transfer.
- Scope of the transfer.
- Skilled personnel and their responsibilities.
- Comparison of materials, equipments, and methods between SU and RU.
- Documented evidence of each stage of process control and critical stages.
- The transfer of documents should be achieved satisfactorily.
- Assessment of CCP (critical control points).
- Assessment of experimental process for manufacturing.
- Experimental process assessment for standardization and analysis.
- Information of different batches.
- Process validation.
- Assessment of out of specification or deviated results and change control.
- Analysis of finished products.
- Documented reports of analysis.
- Retention of reference materials, active ingredients, intermediate products, and finished products.
- Approval of competent authorities or project manager.
Quality Risk Management (QRM)
In the life-cycle of any pharmaceutical product, the quality aspect is very important. The risk of quality variation in the pharmaceutical product can be assessed, controlled, and communicated by a systematic process called QRM. It has been mentioned in ICH guideline Q9.
The basic principle of QRM is the assessment and evaluation of the associated risks based on scientific knowledge and evidence to maintain the quality of the product and customer satisfaction.
The process of QRM can be summarized in the following different steps (Fig.1):
Step (1) QRM initiation:
To initiate the process of QRM the following plan can be followed:
- Types of risk and problem.
- Questions regarding risks.
- Information regarding quality and potential hazards.
- Information of background and raw data.
- Assessment of required resources.
- Specification of the time limit.
Step (2) Risk Assessment:
This may include the following:
- Identification of Hazards: Systematic process to identify the risks and hazards.
- Analysis of Risks: Qualitative and quantitative estimations of hazards.
- Evaluation of Risks: Comparison of identified and analyzed hazards.
Step (3) Risk Control:
The basic purpose of risk control is to reduce or eliminate the risks. It should be based on the following points:
- The acceptance level of risks.
- Possible steps to reduce or eliminate the risks.
- Balance among benefits, risks, and resources.
(a) Reduction of Risks: The level of risk when exceeds the acceptance criteria, the reduction of risks should be followed. Detection of risk assessment and process control can reduce the level of risks.
(b) Acceptance of Risks: It is the decision to accept the risk.
Step (4) Results of QRM and Risk Reviews:
The review of a result obtained from the QRM process is a part of the quality management system. Results of the QRM process should be documented, reviewed, inspected, audited, and possible change control is suggested. The unsatisfactory review process will suggest the failure of the investigation and the process can be started from the risk assessment step. Step
(5) Risk Communication:
This is the communication process of the data of the risk management system. The risk management system can be communicated at any step of the risk management process (Risk assessment, control, and review process, in Fig.1 mentioned as a dotted line). The well-documented result of the QRM process should be submitted and communicated (in Fig.1 mentioned as a solid line) to the parties.
This guideline is very important in the pharmaceutical industry for QRM. The process is applicable for the pharmaceutical product from manufacturing to the inspection process.

Technology Transfer Related Documents
It is also called a non-disclosure agreement (NDA). It is used to protect the proprietary nature of the technology and retain the confidentiality of technology or invention. The drafting of the appropriate clauses can be essential for the maintenance of the value of the technology. The need for this agreement is due to the increase in competition and the new technologies can be exploited. Thus it is necessary to obtain protection to the continuous innovation process through confidentiality agreements.
The license agreement is generally referred to the licensing of intellectual property rights such as; patents, trademarks, copyrights, etc. This agreement has a role in maintaining the confidentiality and secrecy aspects of the contract.
MoU stands for Memorandum of Understanding. It is a negotiated agreement and contract between the Government and the Management of the Central Public Sector Enterprise (CPSE). MoUs are used either when the parties do not imply a legal commitment or where the parties cannot create a legally enforceable agreement.
