Background: Psoriasis, a chronic, inflammatory skin disease, requires long-term therapy. Risankizumab is a humanized immunoglobulin G1 monoclonal antibody that specifically inhibits interleukin 23 by binding to its p19 subunit.

Objective: The authors assessed the efficacy and safety of risankizumab compared with methotrexate in adults with moderate-to-severe plaque psoriasis.

Background And Aims: Normalization of high-sensitivity C-reactive protein [hs-CRP] and fecal calprotectin [FCP] are suggested Crohn's disease [CD] intermediate treatment targets. This analysis evaluates achievement of biomarker normalization and the relationship between improvements in biomarker concentrations and clinical and endoscopic outcomes among patients treated with risankizumab.

Methods: This post hoc analysis included patients with moderately to severely active CD and elevated baseline hs-CRP [> 5 mg/L] or FCP [> 250 µg/g] concentrations from the 12-week ADVANCE and MOTIVATE induction studies, and the 52-week FORTIFY maintenance study.

Background: Risankizumab is efficacious and well tolerated in adults with moderately to severely active Crohn's disease (CD).

Aim: To evaluate the corticosteroid-sparing effect of risankizumab in CD.

Methods: During the 12-week induction period, patients maintained stable baseline corticosteroid doses, up to 20 mg/day prednisone or equivalent.

Article Synopsis
  • * Exposure-response analyses revealed that while higher drug levels improved outcomes, simply using a higher induction dose did not further enhance clinical remission or endoscopic response shortly after treatment.
  • * In the maintenance phase, consistent response rates were observed, indicating that average drug concentration was more critical for efficacy, and future research is necessary to explore these findings for other conditions.

Background And Aims: Durable clinical remission, endoscopic healing, and biomarker normalization are key treatment goals for Crohn's disease. The selective anti-interleukin-23 p19 inhibitor risankizumab has demonstrated efficacy and safety in moderately to severely active Crohn's disease. This post-hoc analysis of data from the pivotal risankizumab maintenance study assessed whether risankizumab maintenance therapy sustained the clinical and endoscopic outcomes achieved with risankizumab induction therapy.

Introduction: In patients with moderate to severe Crohn's disease (CD), intravenous induction and subcutaneous maintenance dosing with risankizumab was efficacious and well tolerated. Long-term management of CD via self-administration of risankizumab using an on-body injector (OBI) may improve treatment adherence through convenience and ease of use.

Methods: Within the FORTIFY maintenance study, 46 patients from the United States (US) sites participated in an open-label extension Substudy and received 180 mg or 360 mg risankizumab delivered subcutaneously via OBI [360 mg (2.

Background: There is a great unmet need for new therapeutics with novel mechanisms of action for patients with Crohn's disease. The ADVANCE and MOTIVATE studies showed that intravenous risankizumab, a selective p19 anti-interleukin (IL)-23 antibody, was efficacious and well tolerated as induction therapy. Here, we report the efficacy and safety of subcutaneous risankizumab as maintenance therapy.

Background: Risankizumab, an interleukin (IL)-23 p19 inhibitor, was evaluated for safety and efficacy as induction therapy in patients with moderately to severely active Crohn's disease.

Methods: ADVANCE and MOTIVATE were randomised, double-masked, placebo-controlled, phase 3 induction studies. Eligible patients aged 16-80 years with moderately to severely active Crohn's disease, previously showing intolerance or inadequate response to one or more approved biologics or conventional therapy (ADVANCE) or to biologics (MOTIVATE), were randomly assigned to receive a single dose of intravenous risankizumab (600 mg or 1200 mg) or placebo (2:2:1 in ADVANCE, 1:1:1 in MOTIVATE) at weeks 0, 4, and 8.

Article Synopsis
  • - The SERENE CD trial studied the effectiveness of higher vs. standard induction doses of adalimumab and two maintenance strategies (clinically adjusted vs. therapeutic drug monitoring) in treating moderate to severe Crohn's disease.
  • - Results indicated that there was no significant difference in clinical remission rates at week 4 or endoscopic response at week 12 between patients who received higher and standard induction doses.
  • - Both maintenance strategies showed similar effectiveness by week 56, and adalimumab was generally well tolerated with no new safety issues reported.

Purpose: To evaluate long-term efficacy and safety of extended treatment with adalimumab in patients with noninfectious intermediate, posterior, or panuveitis.

Design: Open-label, multicenter, phase 3 extension study (VISUAL III).

Participants: Adults who had completed a randomized, placebo-controlled phase 3 parent trial (VISUAL I or II) without treatment failure (inactive uveitis) or who discontinued the study after meeting treatment failure criteria (active uveitis).

: To assess efficacy of adalimumab versus placebo in patients with active or inactive noninfectious intermediate, posterior, or panuveitis across different etiologies.: VISUAL I (V-I) and VISUAL II (V-II) clinical trials included adults with active or inactive uveitis, respectively, randomized to receive adalimumab or placebo. In a post hoc subgroup analysis, time to treatment failure (TTF) starting at week 6 (V-I) or week 2 (V-II) was analyzed using the Kaplan-Meier method.

Article Synopsis
  • Non-infectious uveitis (NIU) is a disease that affects the eyes and can cause pain, redness, and even blindness, but it can be treated.
  • Many healthcare professionals need to work together to diagnose and manage NIU, as treatments may vary from person to person.
  • New medicines called biologics and improved therapies may help patients with NIU while avoiding some harmful side effects from traditional treatments like corticosteroids.

Purpose: Report global adalimumab safety and efficacy outcomes in patients with non-infectious uveitis.

Methods: Adults with non-infectious intermediate, posterior, or panuveitis were randomized 1:1 to receive placebo or adalimumab in the VISUAL I (active uveitis) or VISUAL II (inactive uveitis) trials. Integrated global and Japan substudy results are reported.

Background: Patients with noninfectious uveitis are at risk for long-term complications of uncontrolled inflammation, as well as for the adverse effects of long-term glucocorticoid therapy. We conducted a trial to assess the efficacy and safety of adalimumab as a glucocorticoid-sparing agent for the treatment of noninfectious uveitis.

Methods: This multinational phase 3 trial involved adults who had active noninfectious intermediate uveitis, posterior uveitis, or panuveitis despite having received prednisone treatment for 2 or more weeks.

Background: Non-infectious uveitis is a potentially sight-threatening ocular disorder caused by chronic inflammation and its complications. Therapeutic success is limited by systemic adverse effects associated with long-term corticosteroid and immunomodulator use if topical medication is not sufficient to control the inflammation. We aimed to assess the efficacy and safety of adalimumab in patients with inactive, non-infectious uveitis controlled by systemic corticosteroids.

Little leaguer's shoulder, a stress injury of the proximal humeral physis, should be considered in the differential diagnosis for an adolescent baseball player with shoulder pain, especially if the player is pitching regularly in a competitive environment. While roentgenographs may or may not be helpful, depending on the duration and severity of the injury, we report the MRI appearance of a case of little leaguer's shoulder. We found MRI helpful in diagnosing injury to the growth plate that was radiographically occult; furthermore, we were able to document the patient's progress with a follow-up MRI examination, which showed improvement with treatment.
