What could be a consequence of a protocol violation in a clinical trial?

A protocol violation in a clinical trial refers to any deviation from the protocol that was initially approved by the regulatory authority and the ethics committee. Such violations can have significant negative implications for the study.

Compromised study validity is a major concern because a protocol violation can introduce bias or affect the consistency of data collection and analysis. This can lead to results that do not accurately reflect the true effects of the intervention being studied. For instance, if participants do not adhere to the treatment regimen outlined in the protocol, the resulting data may not provide a clear picture of the treatment's effectiveness.

In addition, participant safety may also be compromised. Protocols are designed to protect the well-being of participants, outlining inclusion/exclusion criteria, dosing regimens, monitoring procedures, and other aspects critical to minimizing risks. Any deviation from these established guidelines may expose participants to unknown risks, thereby undermining the ethical responsibility to ensure their safety throughout the trial.

The other options, such as improved study findings, enhanced credibility of the research team, and reduced financial costs, do not accurately reflect the consequences of protocol violations. Instead, these options suggest positive outcomes that are unlikely to arise from such deviations. A protocol violation typically leads to challenges and detracts from the overall integrity and success of
