Introduction
The concept of treat to target (T2T) in Crohn’s Disease (CD) involves optimising therapy until a predetermined clinically relevant endpoint is met. In recent years, this endpoint has most commonly been a short-term biomarker response or endoscopic healing, but this has typically been juxtaposed with long-term patient reported outcomes (PROs) such as health-related quality of life (HRQoL) [1]. The international STRIDE-2 guidelines emphasise the need for monitoring at frequent intervals to ensure that treatment targets agreed at the commencement of any therapy are actually being achieved. One of the big unknowns of such strategies, requiring frequent monitoring, has been their cost-efficiency. However, concerns about cost have been balanced by arguments that adequate monitoring may allow earlier and more appropriate initiation of advanced therapies, which may then result in better longer-term outcomes [2].
STARDUST (NCT03107793) was a phase 3b, open-label, randomised controlled trial that compared ustekinumab (UST) T2T with standard-of-care (SoC) treatment strategies in adult patients with moderate to severe CD. The primary results from this trial have previously been reported, and it is notable that endoscopic and biomarker endpoints were not statistically different between the two treatment strategies [3]. However, it is also worth noting that while more patients in the T2T arm received q4w (4-weekly) dosing of UST (18.4% vs 0%), more patients in SoC received q8w (8-weekly) dosing (61.5% vs 38.8%). The original STARDUST trial included 440 patients, of whom 336 completed the first year of treatment and 323 (T2T, n=147; SoC, n=176) were subsequently enrolled to the long-term extension (LTE) period until week 104 (2-year mark). In this study, Panes et al. report on the HRQoL outcomes from patients in the LTE study from the STARDUST trial.
