Results from the Phase 3 GRAVTI study by Hart et al. showed that SC induction followed by SC maintenance treatment with guselkumab resulted in superior clinical and endoscopic improvements in participants with moderately to severely active CD through 48 weeks compared with placebo. Hart et al. evaluated efficacy and safety of guselkumab SC induction followed by SC maintenance in participants with moderately to severely active CD in a    treat-through design.

This study by Sobotkova et al. confirmed the similar efficacy and overall safety of biological treatment for psoriasis in older and younger adult patients. Authors compared a large cohort of older adults during the first year of biological treatment for psoriasis to younger adult patients with similar characteristics to advance knowledge about the biologic treatment of psoriasis in older patients.

This study by Mortato et al. enhanced the limited safety data on guselkumab in patients with moderate-to-severe plaque psoriasis who have clinically relevant infectious and oncological comorbidities as well as concomitant heart disease. Authors assessed clinical outcomes and safety of guselkumab in a large cohort of patients with concomitant chronic infection, cancer or heart disease over a long follow-up period, addressing critical gaps in clinical evidence.

Baraliakos et al. compared real-world effectiveness of upadacitinib, TNF inhibitors, or IL-17 inhibitors following inadequate response to an initial TNF inhibitor in patients with axSpA. Upadacitinib was associated with greater reductions in pain and fewer affected joints compared with switching to a second TNF inhibitor or IL-17 inhibitor.

In this nationwide observational study, ixekuzumab was mainly used in patients with axSpA and PsA who had previously failed multiple b/tsDMARDs, including other IL-17 inhibitors. Although prior IL-17 treatment was associated with increased risk of withdrawal in both groups, the relatively high retention rates and improvements in all disease outcomes suggest ixekizumab as a viable option for challenging patients with multiple b/tsDMARD failures.

Wang et al. validated the effectiveness and safety of UPA in this real-world study of Chinese PsA patients. UPA demonstrated comparable effectiveness to secukinumab (SEC) in psoriatic lesion improvement while showing comparable joint symptom relief compared with adalimumab (ADA), coupled with a favourable safety profile.

In this nationwide study of Swedish PsO and PsA patients treated with ustekinumab, etanercept, adalimumab, or secukinumab, spanning more than 10 years, the overall risk of MACE was low across treatment groups. There was no meaningful difference in risk of MACE between ustekinumab and the other treatments.

Gooderham et al. observed that roflumilast foam, 0.3%, improved signs and symptoms of PsO on the scalp and body, including pruritus, with low rates of AEs in patients ≥12 years of age. Authors assessed efficacy and safety of roflumilast foam, 0.3%, versus vehicle administered QD for 8 weeks in patients with PsO of the scalp and body.

A randomized Phase II study of efmarodocokin alfa, an interleukin-22 agonist, versus vedolizumab in patients with ulcerative colitis

Clinical Gastroenterology and Hepatology 2025;23:1387–1397 doi: 10.1016/j.cgh.2024.11.013

Danese et al. observed that efmarodocokin alfa did not demonstrate efficacy compared to the PBO, and this Phase II study ended early for futility; however, there was evidence of target engagement (skin AEs, regenerating islet derived protein 3-alpha).

Brandt-Jürgens et al. identified a difference between the incidence rates of uveitis in patients with PsA or axSpA when treated with secukinumab compared to placebo. The authors conducted a post hoc analysis of 11 placebo-controlled clinical trials which has observed that uveitis incidences in patients with PsA are consistent with clinical trial data, and patients with axSpA show a lower incidence of uveitis compared to other publications.
