For drug development, the clinical phases start with testing for drug safety in a few human subjects, then expand to many study participants (potentially tens of thousands) to determine if the treatment is effective. [1] Clinical research is conducted on drug candidates, vaccine candidates, new medical devices, and new diagnostic assays.
The drug pipeline is also sometimes restricted to a particular drug class or extended to mean the process of discovering drugs (the research and development pipeline). [3] The R&D pipeline involves various phases that can broadly be grouped in 4 stages: discovery, pre-clinical, clinical trials and marketing (or post-approval).
Clinical – efficacy and safety (clinical trials) 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.
This initiative aimed at dealing with the high attrition levels observed in the clinical phase. It also attempted to offer flexibility to investigators to find the optimal clinical benefit without affecting the study's validity. Adaptive clinical trials initially came under this regime. [8]
Randomized controlled trial [5]. Blind trial [6]; Non-blind trial [7]; Adaptive clinical trial [8]. Platform Trials; Nonrandomized trial (quasi-experiment) [9]. Interrupted time series design [10] (measures on a sample or a series of samples from the same population are obtained several times before and after a manipulated event or a naturally occurring event) - considered a type of quasi ...
Clinical research is often conducted at academic medical centers and affiliated research study sites. [2] These centers and sites provide the prestige of the academic institution as well as access to larger metropolitan areas, providing a larger pool of medical participants. These academic medical centers often have their internal Institutional ...
Clinical research is the aspect of biomedical research that addresses the assessment of new pharmaceutical and biological drugs, medical devices and vaccines in humans. General topics [ edit ]
An electronic data capture (EDC) system is a computerized system designed for the collection of clinical data in electronic format for use mainly in human clinical trials. [1] EDC replaces the traditional paper-based data collection methodology to streamline data collection and expedite the time to market for drugs and medical devices.
