PROCEDURE ON TECHNOLOGY TRANSFER 
Objective of this procedure is to provide a guideline on the transfer of technology from R&D to manufacturing site and from one manufacturing site to another manufacturing site.
Scope:
This procedure is applicable for the technology transfer of process, method, knowledge from development stage to manufacturer site or from one manufacturer site to another manufacturing site.
Responsibilities

  • It is the responsibility of sending site cross functional department (Quality, R&D, Regulatory, Production and Engineering) to transfer the manufacturing, packaging, analytical technologies & associated training/knowledge to the receiving site through an approved protocol.
  • All the cross functional department (Quality, R&D, Regulatory, Production and Engineering) of receiving site are responsible to receive the complete technologies and knowledge from sending site and approval on the final tech- transfer report.

Procedure

  1. Transfer of technology is defined as “a logical procedure which control the transfer of any process together with its documentation and professional expertise between development and manufacturer or between manufacturer sites”. It is a systematic procedure that is followed in order to pass the documented knowledge and experience gained during development and or commercialization to an appropriate, responsible and authorized party of both sites.
  2. Transfer of technology shall be documented in a planned approach using trained and knowledgeable personnel working within quality system, with documentation of data covering all aspects of development, production and quality control.
  3. Any technology transfer will be managed by a team comprising members from different department; R&D, QC, Production, Warehouse, QA, Engineering etc. who involved in the dispensing of material, manufacturing, packing, analysis. A clear responsibilities shall be define in technology transfer protocol.
  4. A formal agreement between both parties will be made which specifies clear responsibilities before, during and after technology transfer.
  5. A transparency between both parties shall be maintain during technology transfer because any lack of transparency may lead to ineffective transfer of technology.
  6. For the successful technology transfer following general principal and requirement should be met;
  • Project plan shall be encompass the quality aspects of the project and plan should be based on the quality risk management principles to identify all the hazards and their mitigation plan.
  • Technology transfer shall be handled through change control procedure.
  • A comprehensive technical & regulatory gap assessment between sending site and receiving site shall be done before technology transfer.
  • During technical and regulatory gap assessment following points shall be considered but not limited to:
  • Equipment equivalence of sending site and receiving site w.r.t. capacity, working principle shall be consider during risk assessment, if both site equipment are different in terms of capacity and working principle then adequate risk mitigation plan shall be proposed like process optimization, critical control parameter identification & process validation with receiving site equipment, batch size determination based on the equipment capacity etc.
  • Manufacturing formula, method of manufacture, bulk specification and finished goods specification should be freeze and approved before transfer of technology.
  • Area classification of both sending site and receiving site shall be verified for its equivalence. Classification of both site where product manufactured should be same and qualified against a predefined standard and raw material and product requirement like relative humidity, temperature, non-viable and viable counts, differential pressure etc.
  • Water quality (raw water, purified water, water for injection, pure steam) of sending site and receiving site shall be assess for its equivalence. Water is the main source of microbial proliferation so microbial limit should not be more than finished goods specification of product and water system should be qualified against pre-defined specification before its use.
  • Availability of all other critical utilities shall be ensure before technology transfer. All the critical utilities and its capacity like pressure, purity, piping and design should match with the sending site critical utilities used in the manufacturing/ packaging of respective product.
  1. Apart from all technical details personnel knowledge transfer is also required to make technology transfer successful so all the SME (Subject Matter Expert) of sending site is responsible to provide the technical / operational / analytical training to the receiving site respective area personnel.
  2. In case of new product development and transfer to the manufacturing site from R&D analytical method to be developed by R&D and suitability of that method shall be verified at manufacturing site quality control laboratory. In case of technology transfer from one manufacturing site to another manufacturing site responsible person of sending site quality control shall be transferred method at receiving site and trained to all the personnel. Analytical method transfer activity shall be done through approved protocol and method transfer report shall be approved by both parties (sending site and receiving site) then only analytical method transfer will be treated as confirm
  3. If method is available in pharmacopoeia then pharmacopoeia method shall be followed.
  4. Technology transfer shall be performed through an approved protocol which consist following but not limited to;Objective: A clear objective in the protocol is required which state that this protocol is applicable for the technology transfer of “Product, Dose” from “sending site with complete address” to “receiving site with complete address- facility”
  • Scope
  • Key personnel and their responsibilities (Both sending site and receiving site)
  • A comparison of material, method, and equipment with details of action plan if any difference observed
  • The transfer stages with documented evidence that each stage critical stages has been satisfactory accomplished before next commences.
  • Identification of critical control points
  • Experimental design and acceptance criteria for analytical method
  • Project plan for trial batches (optimization batches), qualification batches and process validation batches.
  • Training and skill development
  • Protocol approval
  1. Technology transfer protocol and associated other protocol like feasibility trial protocol, process optimization, process validation, packaging validation, analytical method transfer or method validation protocol shall be executed jointly by sending site and receiving site respective personnel to understand the process and to gain process based knowledge.
  2. A final technology transfer summery report with conclusion shall be prepared and finally agreed and approved by sending site and receiving site stakeholder.
  3. Any changes during technology transfer shall be handled through change control procedure followed by risk assessment.

CRITICAL STAGES OF TECHNOLOGY TRANSFER AND THEIR ASSESSMENT:

  • Starting Material Specification and other relevant functional characteristics of the starting material (both API & raw excipients) to be used at receiving unit that shall be same. Any properties of material which can influence the product quality that shall be identified…Following information shall be gathered about material during any technology transfer but not limited to:
  • Manufacturer details; their approval status, material route of synthesis; flow chart of process control and intermediate which are used in the manufacturing of raw material
  • Any volatile impurities, use of any carcinogenic material during synthesis or any other impurities which can impact the product quality.
  • Solubility profile of material
  • Particle size and distribution
  • Density, flow ability
  • Microbiological susceptibility
