In drug development, serious adverse event (SAE) is defined as any untoward medical occurrence during a human drug trial that at any dose Results in death; Is life-threatening; Requires inpatient hospitalization or causes prolongation of existing hospitalization; Results in persistent or significant disability/incapacity
The FDA provides a database for reporting of adverse medical device events called the Manufacturer and User Facility Device Experience Database (MAUDE)[1]. The data consist of voluntary reports since June 1993, user facility reports since 1991, distributor reports since 1993, and manufacturer reports since August 1996, and is open for public view.
The first Iteration was prior to 1998. In 1999, the FDA released version 2.0. CTCAE version 4.0 in 2009 with an update to y version 4.03 in 2010. [2] The current version 5.0 was released on November 27, 2017. Many clinical trials, now extending beyond oncology, encode their observations based on the CTCAE system. It uses a range of grades from ...
Also known as AE (adverse event) or SAE (serious AE) reporting from clinical trials, safety information from clinical studies is used to establish a drug's safety profile in humans and is a key component that drug regulatory authorities consider in the decision-making as to whether to grant or deny market authorization (market approval) for a drug.
For example, a pain-relief drug is tested on 1500 human subjects, and no adverse event is recorded. From the rule of three, it can be concluded with 95% confidence that fewer than 1 person in 500 (or 3/1500) will experience an adverse event. By symmetry, for only successes, the 95% confidence interval is [1−3/ n,1].
An adverse event is described as "any adverse change in health or "side-effect" that occurs in a person who participates in a clinical trial while the patient is receiving the treatment (study medication, application of the study device, etc.) or within a pre-specified period of time after their treatment has been completed."
In many countries, adverse effects are required by law to be reported, researched in clinical trials and included into the patient information accompanying medical devices and drugs for sale to the public. Investigators in human clinical trials are obligated to report these events in clinical study reports. [5]
Postmarketing surveillance is overseen by the Food and Drug Administration (FDA), which operates a system of passive surveillance called MedWatch, to which doctors or the general public can voluntarily report adverse reactions to drugs and medical devices. [7] The FDA also conducts active surveillance of certain regulated products.
