Laboratory screening method for selection of healthy volunteers

Area of Science:

• Clinical Trials
• Biostatistics
• Medical Screening

Background:

• Laboratory screening in Phase I trials is crucial for excluding subclinical illnesses.
• Subclinical illnesses pose risks to participants and can affect study results.
• Current screening methods may lead to non-pertinent exclusions.

Purpose of the Study:

• To propose a new Bayesian probability-based method for laboratory screening in Phase I trials.
• To enhance the security of subject selection.
• To reduce the number of participants excluded based on non-pertinent laboratory findings.

Main Methods:

• Developing a list of diseases to exclude.
• Defining acceptable risk thresholds for each disease.
• Selecting specific diagnostic tests for each disease.
• Calculating test specificity using contingency tables and epidemiological data.
• Integrating specificity with volunteer population data to set inclusion thresholds.

Main Results:

• The proposed Bayesian method offers increased security in volunteer selection for Phase I trials.
• This approach effectively reduces the exclusion of subjects due to non-relevant laboratory abnormalities.
• Improved accuracy in identifying eligible participants for early-phase studies.

Conclusions:

• The Bayesian probability method provides a more rigorous and efficient approach to laboratory screening.
• This method optimizes participant selection, ensuring study integrity and safety.
• Implementation can lead to more reliable Phase I trial outcomes.
