What is safety population?

The Safety Population is used for the analysis of safety, including adverse events, toxicity and laboratory evaluations. A patient should be included if, and only if, they actually received a study treatment (even if it is a placebo).

What is ITT population?

In a randomised trial, the set of all randomised patients is known as the ‘intention to treat population’, or the ITT population. This clinical trial study population is intended to represent suitable patients and to be reflective of what might be seen if the treatment was used in clinical practice.

What is a efficacy analysis?

If there has been a problem with compliance, the investigators can also conduct an efficacy analysis (sometimes referred to as a ‘secondary analysis’), which compares subjects who actually complied with the assigned protocols.

What is per protocol population?

What is a PP Population, or ‘Per Protocol’ Population in a Clinical Trial? The per protocol population, or PP population is usually defined as all patients completing the study without major protocol deviations – that is, those who followed the rules of the study.

What is safe efficacy?

In an intuitive sense, an efficacious and safe medical technology is one that “works” and causes no undue harm. That statement may sound naive to individuals working in the field of health today.

What is analysis population?

A useful tool in studying the electronic structure is population analysis. Population analysis is based upon a decomposition of the electronic density into atomic contributions, such that nominal charges may be assigned to each atom.

What is the difference between ITT and TOT?

The average difference between the two groups is $100. This is the intent-to-treat (ITT) estimate. Because everyone who was intended to be treated actually received the $100 and noone in the control group was treated, the ITT estimate is also the treatment-on-the-treated (TOT).

How is efficacy calculated?

A vaccine’s efficacy is measured in a controlled clinical trial and is based on how many people who got vaccinated developed the ‘outcome of interest’ (usually disease) compared with how many people who got the placebo (dummy vaccine) developed the same outcome.

How do you prove efficacy?

Efficacy can be assessed accurately only in ideal conditions (ie, when patients are selected by proper criteria and strictly adhere to the dosing schedule). Thus, efficacy is measured under expert supervision in a group of patients most likely to have a response to a drug, such as in a controlled clinical trial.

What is ICH e9?

This document provides guidance on the design, conduct, analysis and evaluation of clinical trials of an investigational product in the context of its overall clinical development. It presents a structured framework for clinical trial planning, conduct, data collection and interpretation of data analyses.
