Background

The main issue to validating new molecules in the field of IBD is insufficient patient enrollment into clinical trials, resulting in premature trials termination and cost increase. CT-SCOUT™ platform is a web-based solution to help clinicians to pre-screen potential candidates and facilitating the coordination of the research team. Our aim was to compare the number of patients enrolled in IBD clinical trials in sites equipped or not with CT-SCOUT™.

Methods

We conducted a prospective, multicenter, open-label, observational study in sites participating to phase 3 trials evaluating the efficacy and safety of etrolizumab in ulcerative colitis (UC, Hickory) and in Crohn’s disease (CD, Bergamot). Recruitment figures were provided by the sponsor, and we considered the 21 French sites equipped with CTscout and 134 sites in other countries not equipped with CT-SCOUT™. The primary endpoint was the mean number of patients randomised per site in both trials. Secondary endpoints included a mean number of patients randomised in each study. Patients screened and those finally randomised were compared in sites equipped and non-equipped using one-way ANOVA followed by post-hoc Tukey test and Mann–Whitney test.

Results

During the observational period of 40 months (September 2015–December 2018), 644 and 289 patients were screened and randomised in Hickory and/or Gardenia, respectively. There were 307 and 149 patients in 78 sites for Hickory, and 337 and 140 patients for Bergamot in 102 sites. The mean numbers of screened and randomised patients in CT-SCOUT™ equipped sites vs. non-equipped are given in the table.

French sites equipped with CT-SCOUTTMSites from other countries non-equipped with CT-SCOUTTMP
Screened in both studies (UC + CD)7.553.05<0.001
Randomised in both studies (UC + CD)3.791.28<0.001
Screened in Hickory (UC)9.173.14<0.001
Randomised in Hickory (UC)5.171.28<0.001
Screened in Bergamot (CD)5.942.950.003
Randomised in Bergamot (CD)2.411.280.009

The mean number of patients randomised in Hickory in CT-SCOUT™ sites increased by 4.0 folds as compared with non-equipped sites (p < 0.001). The mean number of patients randomised in Bergamot in CT-SCOUT™ equipped sites has been increased by 1.9-folds as compared with non-equipped sites (p = 0.009).

Conclusion

This multicentric study demonstrated a significant increase in patient recruitment in IBD clinical trials. Randomisation rates were twice to four times higher in equipped sites compared with non-equipped ones. CT-SCOUT™ appears to be a promising digital solution to the global issue of patient enrollment in clinical trials.
