The Common Technical Document (CTD) is a set of specifications for an application dossier for the registration of medicine, designed for use across Europe, Japan, the United States, and beyond. [1]
The Common Technical Document (CTD) is a set of specifications for an application dossier for the registration of medicine, designed for use across Europe, Japan, the United States, and beyond. [1]
The CTD is an internationally agreed format for the preparation of applications regarding new drugs intended to be submitted to regional regulatory authorities in participating countries. It was developed by the European Medicines Agency (EMA, Europe), the Food and Drug Administration (USA) and the Ministry of Health, Labour and Welfare (Japan) starting at World Health Organization International Conference of Drug Regulatory Authorities (ICDRA) at Paris in 1989. [1]
The CTD is maintained by the International Council on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH). [1] [2]
After the United States, European Union and Japan, the CTD was adopted by several other countries including Canada [3] and Switzerland. [1]
Paper CTDs are destined for replacement by their electronic counterparts, the eCTDs.
The Common Technical Document is divided into five modules: [4]
Detailed subheadings for each module are specified for all jurisdictions. The contents of Module 1 and certain subheadings of others differ based on national requirements. However, investigational new drugs meant for emergency use or treatment applications and not for commercial distribution are not subject to the CTD requirements. [5] [6]
Current good manufacturing practices (cGMP) are those conforming to the guidelines recommended by relevant agencies. Those agencies control the authorization and licensing of the manufacture and sale of food and beverages, cosmetics, pharmaceutical products, dietary supplements, and medical devices. These guidelines provide minimum requirements that a manufacturer must meet to assure that their products are consistently high in quality, from batch to batch, for their intended use.
Bioequivalence is a term in pharmacokinetics used to assess the expected in vivo biological equivalence of two proprietary preparations of a drug. If two products are said to be bioequivalent it means that they would be expected to be, for all intents and purposes, the same.
Pharmacovigilance, also known as drug safety, is the pharmaceutical science relating to the "collection, detection, assessment, monitoring, and prevention" of adverse effects with pharmaceutical products. The etymological roots for the word "pharmacovigilance" are: pharmakon and vigilare. As such, pharmacovigilance heavily focuses on adverse drug reactions (ADR), which are defined as any response to a drug which is noxious and unintended, including lack of efficacy. Medication errors such as overdose, and misuse and abuse of a drug as well as drug exposure during pregnancy and breastfeeding, are also of interest, even without an adverse event, because they may result in an adverse drug reaction.
The United States Food and Drug Administration's Investigational New Drug (IND) program is the means by which a pharmaceutical company obtains permission to start human clinical trials and to ship an experimental drug across state lines before a marketing application for the drug has been approved. Regulations are primarily at 21 CFR 312. Similar procedures are followed in the European Union, Japan, and Canada due to regulatory harmonization efforts by the International Council for Harmonisation.
The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) is an initiative that brings together regulatory authorities and pharmaceutical industry to discuss scientific and technical aspects of pharmaceutical product development and registration. The mission of the ICH is to promote public health by achieving greater harmonisation through the development of technical guidelines and requirements for pharmaceutical product registration.
In drug development, serious adverse event (SAE) is defined as any untoward medical occurrence during a human drug trial that at any dose
In drug development and production, good clinical practice (GCP) is an international quality standard, which governments can then transpose into regulations for clinical trials involving human subjects. GCP follows the International Council for Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH), and enforces tight guidelines on ethical aspects of clinical research.
The electronic common technical document (eCTD) is an interface and international specification for the pharmaceutical industry to agency transfer of regulatory information. The specification is based on the Common Technical Document (CTD) format and was developed by the International Council for Harmonisation (ICH) Multidisciplinary Group 2 Expert Working Group.
In drug development and medical device development the Investigator's Brochure (IB) is a comprehensive document summarizing the body of information about an investigational product obtained during a drug trial. The IB is a document of critical importance throughout the drug development process and is updated with new information as it becomes available. The purpose of the IB is to compile data relevant to studies of the IP in human subjects gathered during preclinical and other clinical trials.
Safety pharmacology is a branch of pharmacology specialising in detecting and investigating potential undesirable pharmacodynamic effects of new chemical entities (NCEs) on physiological functions in relation to exposure in the therapeutic range and above.
A glossary of terms used in clinical research.
The following outline is provided as an overview of and topical guide to clinical research:
Regulated Product Submission (RPS) is a Health Level Seven (HL7) standard designed to facilitate the processing and review of regulated product information. RPS is being developed in response to performance goals that the U.S. Food and Drug Administration (FDA) is to achieve by 2012, as outlined in the Prescription Drug User Fee Act (PDUFA). In addition to the U.S., regulatory agencies from Europe, Canada, and Japan are at varying levels of interest and participation. Currently, the second release of RPS is in development.
The certificate of pharmaceutical product is a certificate issued in the format recommended by the World Health Organization (WHO), which establishes the status of the pharmaceutical product and of the applicant for this certificate in the exporting country; it is often mentioned in conjunction with the electronic Common Technical Document (eCTD). A CPP is issued for a single product, because manufacturing arrangements and approved information for different pharmaceutical forms and strengths can vary. The CPP is mentioned in World Trade Organization documents, although the tightly regulated products are subject to bilateral trade agreements or regional trade agreements. The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) has instituted standards for this purpose but it is unclear how the ex-ICH countries operate their health regulators.
Marketing authorisation is the process of reviewing and assessing the evidence to support a medicinal product, such as a drug, in relation to its marketing, finalised by granting of a licence to be sold.
The Pharmaceuticals and Medical Devices Agency (PhMDA) is an Independent Administrative Institution responsible for ensuring the safety, efficacy and quality of pharmaceuticals and medical devices in Japan. It is similar in function to the Food and Drug Administration in the United States, the Medicines and Healthcare products Regulatory Agency in the United Kingdom, the Spanish Agency of Medicines and Medical Devices in Spain or the Food and Drug Administration in the Philippines.
In medicine, a clinical study report (CSR) on a clinical trial is a document, typically very long, providing much detail about the methods and results of a trial. A CSR is a scientific document addressing efficacy and safety, not a sales or marketing tool; its content is similar to that of a peer-reviewed academic paper. Results of trials are usually reported in a briefer academic journal paper, but methodological flaws are often glossed over in the briefer paper.
Guidances for statistics in regulatory affairs refers to specific documents or guidelines that provide instructions, recommendations, and standards pertaining to the application of statistical methodologies and practices within the regulatory framework of industries such as pharmaceuticals and medical devices. These guidances serve as a reference for statisticians, researchers, and professionals involved in designing, conducting, analyzing, and reporting studies and trials in compliance with regulatory requirements. These documents embody the prevailing perspectives of regulatory agencies on specific subjects. It is worth noting that in the United States, the term "Guidances" is used, while in Europe, the term "Guidelines" is employed.
