ICH GUIDELINES Presented By: Asra Parveen ( M.Pharm ) DECCAN SCHOOL OF PHARMACY Dar-us- salam , Aghapura , Hyderabad- 01. A.P. India

Wingdings:

What is ICH I nternational C onference On H armonization 2

Calibri:

The International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) It is a unique project that brings together the regulatory authorities of Europe, Japan and the United States and experts from the pharmaceutical industry in the three regions to discuss scientific and technical aspects of product registration. INTRODUCTION 3

Mongolian Baiti:

Need to Harmonize Avoid duplication in tests to conform to different regulatory guidelines. More effective utilization of results. Timely access of patients to safe and effective new drugs. Promote public health. Minimize animal testing without compromising safety & effectiveness. 4

Verdana:

Objectives To increase international harmonization of technical requirements to ensure that safe, effective and high quality medicines are developed. To harmonize technical requirements for registration or marketing approval. To developed and registered pharmaceuticals in the most efficient and cost effective manner. To promote public health. To prevent unnecessary duplication of clinical trials on humans. To minimize the use of animal testing without compromising safety and effectiveness of drug. 5

Nature:

Where is the ICH located? ICH does not have "offices" as such because it is a voluntary cooperative effort of cosponsors from the three regions. The ICH Secretariat is based in Geneva. The biennial meetings and conferences of the ICH Steering Committee rotate between the EU, Japan, and the USA. 6

ICH GUIDELINES:

Current Status of Harmonization: (over 50 harmonized guidelines) Safety (S) Dealing with in vitro & in vivo pre clinical testing Quality (Q) Chemical & Pharmaceutical QA Stability, Specifications, Analytical Efficacy (E) Clinical studies in humans Multidisciplinary (M) Terminology Electronic standards Common Technical Documents The topics 7

What is ICH:

Safety Guidelines(animal studies/Pre clinical studies ) Carcinogenicity Studies Genotoxicity Studies Toxicokinetics and Pharmacokinetics Toxicity Testing Reproductive Toxicology Biotechnological Products Pharmacology Studies Immunotoxicology Studies Joint Safety/Efficacy  (Multidisciplinary) Topic 8

PowerPoint Presentation:

PowerPoint Presentation:

M "Multidisciplinary" Topics Cross-cutting Topics which do not fit uniquely into one of the above categories. M1: Medical Terminology (MedDRA) M2: Electronic Standards for Transmission of Regulatory Information (ESTRI) M3: Timing of Pre-clinical Studies in Relation to Clinical Trials M4: The Common Technical Document (CTD) M5: Data Elements and Standards for Drug Dictionaries 23

Efficacy guidelines (Clinical studies):

The Impact of ICH Enhanced patient safety Streamline development programs Common quality standards Reduce resource requirements Forum for communication Opportunity for industry & regulators to sit across the table Discuss drug development procedure with a common goal of identifying best scientific practice & applying the same uniformly across the globe 24

Clinical Safety :

CONCLUSION The ICH guidelines represent agreed-upon scientific guidance for meeting technical requirements for registration within the three ICH regions - EU, US and Japan. Industry and governments in ICH and non-ICH countries can use the ICH guidelines to address technical issues during the product development process. Harmonised ICH guidelines can reduce duplication in meeting technical requirements, thereby saving financial and material resources.         25
