IMproved PRegnancy Outcome by Early Detection — IMPROvED  

Pregnancy Clinical Trial

Official title:
Personalized Medicine for Pregnant Women: Novel Metabolomic and Proteomic Biomarkers to Detect Pre-eclampsia and Improve Outcome.

Clinical Trial Summary

The overall objective of the IMPROvED project is to develop a sensitive, specific, high-throughput and economically viable early pregnancy screening test for preeclampsia.

This will involve a multicentre, phase IIa clinical predictive study to assess and refine novel and innovative prototype tests based on emerging metabolomic and proteomic technologies developed by SMEs (small to medium size enterprise) within the consortium. The study will i) recruit 5000 first-time pregnant women; ii) establish a high calibre biobank, augmented by accurate clinical metadata; iii) determine whether prototype predictive assays and algorithms translate to the clinical environment; iv) assess potential synergy of a combined metabolomic and proteomic approach and v) progress regulatory approval and development of the selected test into the clinical arena.

Clinical Trial Description

Sample size calculations have been considered extensively and given the complexity of the study; there is no single simple solution. For the purpose of sample size estimation in the overall study, we used a binary outcome and associated measures of sensitivity and likelihood ratio as determinants of the value of these tests. Although the predictive algorithms will produce a continuous risk score, the use of a categorical outcome fits with the final binary decision process (to treat or not to treat) based on the risk score. Based on the lowest estimated prevalence of pre-eclampsia of 3% and a test sensitivity of 93% and a test specificity of 97%, then to be 90% certain that the true specificity of the patient population is no less than 95%, a sample size of 4,800 participants is required. Thus, allowing for patient dropout, a study population of 5,000 women is needed. ;
