(ICH definition – International Conference on Harmonisation of technical requirements for registration of pharmaceuticals for human use)

Adverse Drug Reaction (ADR)
In the pre-approval clinical experience with a new medicinal product or a product’ s new usages, particularly as the therapeutic dose(s) may not be established: all noxious and unintended responses to a medicinal product related to any dose should be considered adverse drug reactions (the phrase ‘ responses to a medicinal product’ meaning that a causal relationship between a medicinal product and an adverse event is at least a reasonable possibility, i.e. the relationship cannot be ruled out).
Regarding marketed medicinal products:  a response to a drug which is noxious and unintended and which occurs at doses normally used in man for prophylaxis, diagnosis, or therapy of diseases or for modification of physiological function.

Adverse event (AE)
Any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. An adverse event (AE) can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.

Applicable regulatory requirement(s)
Any law(s) and regulation(s) addressing the conduct of clinical trials of investigational products.

Approval (in relation to Institutional Review Boards)
The affirmative decision of the Institutional Review Board (IRB) that the clinical trial has been reviewed and may be conducted at the institution site within the constraints set forth by the IRB, the institution, Good Clinical Practice (GCP), and the applicable regulatory requirements.

A systematic and independent examination of trial-related activities and documents to determine whether the evaluated trial-related activities were conducted, and the data recorded, analysed and accurately reported, according to the protocol, sponsor's SOPs, GCP, and the applicable regulatory requirement(s).

A procedure in which one or more parties to the trial are kept unaware of the treatment assignment(s). Single-blinding usually refers to the subject(s) being unaware, and double-blinding usually refers to the subject(s), investigator(s), monitor, and, in some cases, data analyst(s), being unaware of the treatment assignment(s).

Clinical trial/study
Any investigation in human subjects intended to discover or verify the clinical, pharmacological and/or other pharmacodynamic effects of an investigational product(s), and/or to identify any adverse reactions to an investigational product(s), and/or to study absorption, distribution, metabolism, and excretion of an investigational product(s) with the object of ascertaining its safety and/or efficacy. The terms clinical trial and clinical study are synonymous.

Clinical trial/study report

Direct access
Permission to examine, analyse, verify, and reproduce any records and reports that are  important to evaluation of a clinical trial.

Independent Ethics Committee (IEC)
An independent body (an institutional, regional, national, or supranational review board or committee), constituted of medical professionals and non-medical members, whose responsibility it is to ensure protection of the rights, safety and well-being of human subjects involved in a trial and to provide public assurance of that protection, by, among other things, reviewing and approving/providing favourable opinion on the trial protocol, suitability of the investigator(s), facilities, and methods and materials to be used in obtaining and documenting informed consent of the trial subjects.
The legal status, composition, function, operations and regulatory requirements pertaining to Independent Ethics Committees may differ among countries, but should allow the Independent Ethics Committee to act in agreement with GCP as described in this guideline.

Informed consent

Informed consent is documented by means of a written, signed and dated informed consent form.

The act by a regulatory authority(ies) of conducting an official review of documents, facilities, records, and any other resources that are deemed by the authority(ies) to be related to the clinical trial and that may be located at the site of the trial, at the sponsor's and/or contract research organization’ s (CRO’ s) facilities, or at other  establishments deemed appropriate by the regulatory authority(ies).

Institution (medical)
Any public or private entity or agency or medical or dental facility where clinical trials are conducted.

Institutional Review Board (IRB)
An independent body constituted of medical, scientific, and non-scientific members, whose responsibility is to ensure the protection of the rights, safety and well-being of human subjects involved in a trial by, among other things, reviewing, approving, and providing continuing review of trial protocol and amendments and of the methods and materials to be used in obtaining and documenting informed consent of the trial subjects.

Interim clinical trial/study report
A report of intermediate results and their evaluation based on analyses performed during the course of a trial.

A document that describes the objective(s), design, methodology, statistical considerations, and organization of a trial. The protocol usually also gives the background and rationale for the trial, but these could be provided in other protocol referenced documents. Throughout the ICH GCP Guideline the term ‘ protocol’ refers to protocol and protocol amendments.

Protocol amendment
A written description of a change(s) to, or formal clarification of, a protocol.

Quality assurance (QA)
