Study description

This project, entitled Comparative Effectiveness and Safety Studies Using the Target Trial Emulation and Estimand Frameworks (TARGET EU), aims to advance regulatory use of real-world data (RWD) through application of target trial emulation (TTE) and estimand methodologies.

The overarching goal is to generate evidence that bridges randomized controlled trials (RCTs) and observational studies, supporting regulatory decisions where RCTs are infeasible.

TARGET EU comprises four objectives:
(1) to review and assess the integration of TTE with the estimand framework for evaluating drug effectiveness and safety,
(2) to characterise the suitability of diverse European RWD sources for TTE,
(3) to identify regulatory scenarios—such as PASS, PAES, and trials with external comparators—where TTE provides value, and
(4) to establish good practice guidelines for communicating TTE results to regulators.

To achieve these aims, we developed target trial protocols, emulation protocols, and conducted feasibility assessments and analyses across ten distinct case studies.

CS 1 (covid19) (EUPAS1000000995)
CS 2 (lung cancer) (EUPAS1000000987)
CS 3 (dapagliflozin) (EUPAS1000000979)
CS 4 (rivaroxaban) (EUPAS1000001001)
CS 5 (asthma) (EUPAS1000000989)
CS 6 (valsartan) (EUPAS1000001002)
CS 7 (valproate) (EUPAS1000000999)
CS 8 (rsv) (EUPAS1000000993)
CS 9 (tolvaptan) (EUPAS1000001005)
CS 10 (colon cancer) (EUPAS1000000996)

Additional information about each case study can be found in the resources tab within the protocol section.

The overall methodology for the feasibility assessment is described here: EUPAS1000000791.
