1 Preparation of rh-Insulin National Reference standard National Institute of Biologicals Noida Meeting of the Manufacturer’s March 20, 2009

2 WHY the need ╩ There is no National Reference Standard available in our country on rh-Insulin with any metrological trace ability as per ISO guidelines – ╩ The certificate of Analysis also varies from one Manufacturer to another as there are no guidelines and Recommendations laid down for National Reference standard of rh-Insulin incorporated in “ Indian Pharmacopoeia ” ╩ International biological standards are the “ Primary standards ” against which Secondary standards are calibrated. Secondary standards may be - a) National standard, b) Regional standard, c) Working Reference material. rh-Insulin Reference Standard

4 Memorandum of Understanding ╩ All the information of API-bulk material supplied during the study will be treated as confidential and proprietary to the manufacturer ’ s. ╩ A MoU will be developed between a) NIB, b) Industry and c) IPC ╩ All persons involved herein by signing the agreement confirms that there is no financial or vested commercial interest.

6 Steps in establishing National Reference standard 1. Incorporation of human Insulin National Reference Standard in IP-Monograph for Human Insulin 2. Provide collaborators with set of necessary documents 3. Establish – 3.1 Inter laboratory ” collaborative study for selecting a Candidate RS material 3.2 coded material to be distributed maintaining confidentiality 33 Proficiency testing program based on NABL 162 guidelines

7 1. Quantitative uses in assays of rh-insulin bulk & formulation, either by: ╔ Biological methods ╔ Physiochemical method-HPLC 2. Quantitative uses in Limit tests by Physiochemical method-HPLC 3. Qualitative uses in Identification tests, system suitability tests, chromatographic peak markers 4. Method development, evaluation of method performance Intended Use

8 Goals of Collaborative study Selection of rh-insulin Candidate material Obtain API-Bulk material from a major manufacturer of rh-insulin Detailed rh-insulin testing Protocol to include elements of : ╩ Type of tests ╩ No of tests ╩ No of collaborators ╩ Elements of validation ╩ No. of replicates ╩ References to the procedure to be used. ╩ Data recording forms for result compilation Material is Calibrated and Characterized, with regular use of CRM Statistical control in design and Analysis of Results Assign Property values and Uncertainties

9 Assignment of Property Values and Their Uncertainties ╔ Investigation of statistical outliers and/or use of robust statistic ╔ Methods used to assign uncertainties to property values ╔ Acquire time-zero information for future continued-suitability for use of rh-insulin Reference standard ╔ 1 Unit of Human insulin = mg by definition (28.8 IU/mg). ╔ Value is assigned to rh-insulin bulk in IP. ╔ Need to Work Out : Assignment of Property Value to serve as Standard for Assay of 40 IU and 100 IU Insulin preparations.
