CNPR Clinical Trials 5

Question 1

What is an 'open-label' clinical trial?

Accepted Answer

A trial where both participants and investigators know which treatment is being administered

Answer

In an open-label trial, both the participant and the investigator are aware of which treatment is being given, in contrast to blinded designs.

Question 2

What is the primary goal of an adaptive clinical trial design?

Accepted Answer

To allow pre-specified modifications to trial elements based on accumulating data

Answer

Adaptive designs allow pre-specified modifications (e.g., sample size re-estimation, dose selection) based on interim data while preserving statistical integrity.

Question 3

Which document formally defines the objectives, design, methodology, and statistical considerations of a clinical trial?

Accepted Answer

Clinical study protocol

Answer

The clinical study protocol is the master document that defines all aspects of trial conduct including objectives, design, eligibility criteria, endpoints, and statistical methods.

Question 4

What is 'statistical power' in the context of clinical trial design?

Accepted Answer

The probability of detecting a true treatment effect when one exists

Answer

Statistical power is the probability of correctly rejecting the null hypothesis (detecting a true effect), commonly set at 80% or 90% in trial design.

Question 5

What is the Expanded Access (compassionate use) program?

Accepted Answer

A pathway allowing seriously ill patients to access investigational drugs outside of clinical trials

Answer

Expanded Access allows patients with serious or immediately life-threatening conditions to access investigational drugs outside of clinical trials when no comparable alternatives exist.
