True or False: Clinical data is not needed for a new drug application.

The correct answer is that clinical data is indeed necessary for a new drug application. The purpose of the new drug application (NDA) is to demonstrate the safety and effectiveness of a pharmaceutical drug before it can be approved for public use. This process requires comprehensive clinical data gathered through clinical trials, which provide evidence regarding how the drug interacts with humans, its efficacy for the intended use, potential side effects, and overall safety profile.

The submission of this clinical data is essential for regulatory authorities, such as the FDA, to evaluate whether the benefits of the drug outweigh any risks. Without this evidence, the application would be incomplete, and the drug would not be able to gain approval for marketing. Therefore, stating that clinical data is not needed would be inaccurate, as it is a fundamental aspect of the drug evaluation process.
