Reporting Guidelines for Clinical Pharmacokinetic Studies: The ClinPK Statement

Area of Science:

• Pharmacokinetics
• Clinical Research
• Scientific Reporting

Background:

• Transparent reporting is crucial for assessing study validity.
• Reporting guidelines exist for many research types but are absent for clinical pharmacokinetic studies.
• Consistent reporting facilitates knowledge translation and end-user understanding.

Purpose of the Study:

• To create a guideline for transparent and complete reporting of clinical pharmacokinetic studies.
• To address the lack of standardized reporting tools in this field.

Main Methods:

• Systematic literature and regulatory document review.
• Modified Delphi exercise and virtual meetings with 68 international stakeholders.
• Pilot testing of a 24-item checklist on 100 recent clinical pharmacokinetic studies.

Main Results:

• Consensus was reached on a 24-item checklist for reporting clinical pharmacokinetic studies.
• Pilot testing showed 45% of studies complied with at least 80% of checklist items.
• Explanatory text was developed with examples of compliant reporting.

Conclusions:

• Incomplete reporting compromises the assessment of pharmacokinetic research validity.
• The developed guideline promotes transparent and accurate reporting.
• Adoption by researchers, clinicians, and journals will improve consistency and clinical utility assessment.
