Q of the week

Q: Do clinical trials ever go wrong?

Get the Answer: 

PAP TEST

A test to check for cancer of the cervix, the opening to a woman's womb. It is done by removing cells from the cervix. The cells are then prepared so they can be seen under a microscope.

A-B

Adverse Drug Reaction (ADR)
In the pre-approval clinical experience with a new medicinal product or its 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 means 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 (see the ICH Guideline for Clinical Safety Data Management: Definitions and Standards for Expedited Reporting).
Adverse Event (AE)
Any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and 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 (see the ICH Guideline for Clinical Safety Data Management: Definitions and Standards for Expedited Reporting).
Amendment (to the protocol)
See Protocol Amendment.
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 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.
Audit
A systematic and independent examination of trial related activities and documents to determine whether the evaluated trial related activities were conducted, and the data were recorded, analyzed and accurately reported according to the protocol, sponsor's standard operating procedures (SOPs), Good Clinical Practice (GCP), and the applicable regulatory requirement(s).
Audit Certificate
A declaration of confirmation by the auditor that an audit has taken place.
Audit Report
A written evaluation by the sponsor's auditor of the results of the audit.
Audit Trail
Documentation that allows reconstruction of the course of events.

Blinding/Masking
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).
 
 




Opinion Poll

Which one of the following do you think is the most common reason for participating in clinical trials?
 
This opinion poll provides an informal way for the clinical research community to express its views on current topics. The results are not a scientific poll and do not necessarily reflect the percentages of all clinical researchers who agree with these positions.
