Summary
Non-inferiority trials assess if new treatments are not unacceptably worse than existing ones. This paper explores non-inferiority concepts and regulatory perspectives from the European Medicines Agency and US Food and Drug Administration.
Area of Science:
- Clinical Trials Methodology
- Regulatory Science
Background:
- Non-inferiority trials are crucial for evaluating new medical products.
- These trials compare a new product against a well-established standard treatment.
Purpose of the Study:
- To introduce fundamental concepts of non-inferiority trials.
- To discuss regulatory viewpoints on non-inferiority from major health authorities.
Main Methods:
- Conceptual review of non-inferiority trial design.
- Analysis of regulatory guidelines from the European Medicines Agency (EMA) and United States Food and Drug Administration (FDA).
Main Results:
- Defines the core principles and statistical considerations for non-inferiority.
- Highlights key differences and similarities in EMA and FDA approaches to non-inferiority evidence.
Conclusions:
- Understanding non-inferiority is essential for drug development and approval.
- Regulatory alignment and clear guidelines facilitate the evaluation of new medical interventions.

01:27Sources of Self-Esteem III: Social Comparison
Social comparison plays a fundamental role in the evaluation of personal success and self-worth. Rather than assessing our achievements in isolation, we interpret their significance relative to personal goals and critically in comparison to the performance of others. A grade of B in a mathematics exam might elicit pride if one's expectation was a C, yet result in disappointment if an A was anticipated or if peers achieved superior results. These comparative evaluations illustrate how both...
01:28The Looking Glass Self
The concept of the looking-glass self describes how an individual's self-concept is shaped by their perception of how others see them. This psychological theory, first introduced by sociologist Charles Horton Cooley in 1902, posits that self-identity emerges in a social context and is influenced by the judgments—real or imagined—of others.Research suggests that individuals frequently overestimate how positively others perceive them. This is particularly evident in physical self-perception,...
03:00Self-Evaluation: Self-Enhancement and Self-Verification
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
02:45Self-Discrepancy Theory
One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.
02:57The Sense of Self: Reflected Self-Appraisal and Social Comparison
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...
01:29Self-Discrepancy and Its Effects
Self-discrepancy theory explains how people compare their actual self to their ideal and ought selves and how mismatches between these self-guides can lead to emotional distress. Developed by E. Tory Higgins, the theory distinguishes among three components of self-concept: the actual self, the ideal self, and the ought self. These refer respectively to how individuals perceive themselves, how they aspire to be, and how they believe they are obligated to be. Emotional well-being, self-esteem,...
