Spesolimab treatment for the prevention of flares in people with generalized pustular psoriasis (GPP): a plain language summary of the Effisayil â„¢ 2 study
What is this study about?:
Generalized pustular psoriasis (shortened to GPP) is a rare, potentially life-threatening disease in which pus-filled blisters or pustules may suddenly form all over the body. The drug spesolimab has been approved to treat worsening GPP (known as flares) in many countries. However, it was not known if spesolimab could prevent the symptoms of GPP. This summary reports the results from a clinical study called Effisayilâ„¢ 2, that was done to understand if spesolimab was a safe and effective way to prevent flares in people with GPP. In the study, 123 participants, recruited in 20 different countries, were given one of three different doses of spesolimab (low, medium, or high) or a non-active medicine (placebo) over 48 weeks.
What were the results?:
Participants who received spesolimab had fewer GPP flares over the course of the 48-week study. Different doses of the drug were tested and compared to placebo, and a high dose of spesolimab worked better than low and medium doses. Using spesolimab also reduced the chance of developing skin symptoms, such as redness or pustules, and prevented quality of life getting worse over 48 weeks. While some participants experienced unwanted effects, they were mostly mild or moderate and most did not appear to be caused by spesolimab, or the dose at which it was given.
What do the results of the study mean?:
The results indicate that a high dose of spesolimab works well to prevent GPP flares and stop the disease getting worse. Health authorities are looking at the results of this study to decide if spesolimab can also be prescribed for the prevention of GPP flares
Spesolimab Efficacy and Safety in Patients with Moderate-to-Severe Palmoplantar Pustulosis: A Multicentre, Double-Blind, Randomised, Placebo-Controlled, Phase IIb, Dose-Finding Study
Abstract Introduction We evaluated the anti-interleukin-36 receptor antibody spesolimab in patients with moderate-to-severe palmoplantar pustulosis (PPP). Methods This phase IIb trial comprised a loading dose period to week (W) 4, then maintenance dosing to W52. Patients were randomised 2:1:1:1:2 to subcutaneous spesolimab 3000 mg to W4 then 600 mg every 4 weeks (q4w), spesolimab 3000 mg to W4 then 300 mg q4w, spesolimab 1500 mg to W4 then 600 mg q4w, spesolimab 1500 mg to W4, 300 mg q4w to W16 then 300 mg every 8 weeks (q8w), or placebo switching to spesolimab 600 mg q4w at W16. The primary efficacy endpoint was percentage change from baseline in Palmoplantar Pustular Area and Severity Index (PPP ASI) at W16. Secondary endpoints included a Palmoplantar Pustular Physician’s Global Assessment (PPP PGA) score of 0/1. Safety (including adverse events [AEs], local tolerability) was assessed. Results 152 patients were treated. The primary endpoint was not met; mean differences for spesolimab versus placebo ranged from − 14.6% (95% confidence interval [CI]: − 31.5%, 2.2%) to − 5.3% (95% CI: − 19.1%, 8.6%); none reached significance. At W16, 23 (21.1%) and two (4.7%) patients in the combined spesolimab and placebo groups, respectively, achieved PPP PGA 0/1 (mean difference 16.4%; 95% CI: 3.8%, 25.7%), increasing to 59 (54.1%; combined spesolimab) and 12 (27.9%; placebo switch to spesolimab) patients at W52. Non-Asian patients had significant improvements in the primary endpoint (mean difference − 17.7%; nominal P = 0.0394) and PPP PGA 0/1 at W16 with spesolimab versus placebo. Rates of AEs and AE-related discontinuations were similar for spesolimab and placebo. Local tolerability events and injection-site reactions were more frequent with spesolimab than placebo. Conclusion The primary objective to demonstrate a non-flat dose–response relationship and proof-of-concept was not achieved; improvements with spesolimab occurred in secondary endpoints and in non-Asian patients, indicating potential modest benefits. Spesolimab was generally well tolerated (ClinicalTrials.gov NCT04015518)
Nintedanib in Progressive Fibrosing Interstitial Lung Diseases.
Preclinical data have suggested that nintedanib, an intracellular inhibitor of tyrosine kinases, inhibits processes involved in the progression of lung fibrosis. Although the efficacy of nintedanib has been shown in idiopathic pulmonary fibrosis, its efficacy across a broad range of fibrosing lung diseases is unknown. In this double-blind, placebo-controlled, phase 3 trial conducted in 15 countries, we randomly assigned patients with fibrosing lung disease affecting more than 10% of lung volume on high-resolution computed tomography (CT) to receive nintedanib at a dose of 150 mg twice daily or placebo. All the patients met criteria for progression of interstitial lung disease in the past 24 months despite treatment and had a forced vital capacity (FVC) of at least 45% of the predicted value and a diffusing capacity of the lung for carbon monoxide ranging from 30 to less than 80% of the predicted value. Randomization was stratified according to the fibrotic pattern (a pattern of usual interstitial pneumonia [UIP] or other fibrotic patterns) on high-resolution CT. The primary end point was the annual rate of decline in the FVC, as assessed over a 52-week period. The two primary populations for analysis were the overall population and patients with a UIP-like fibrotic pattern. A total of 663 patients were treated. In the overall population, the adjusted rate of decline in the FVC was -80.8 ml per year with nintedanib and -187.8 ml per year with placebo, for a between-group difference of 107.0 ml per year (95% confidence interval [CI], 65.4 to 148.5; P<0.001). In patients with a UIP-like fibrotic pattern, the adjusted rate of decline in the FVC was -82.9 ml per year with nintedanib and -211.1 ml per year with placebo, for a difference of 128.2 ml (95% CI, 70.8 to 185.6; P<0.001). Diarrhea was the most common adverse event, as reported in 66.9% and 23.9% of patients treated with nintedanib and placebo, respectively. Abnormalities on liver-function testing were more common in the nintedanib group than in the placebo group. In patients with progressive fibrosing interstitial lung diseases, the annual rate of decline in the FVC was significantly lower among patients who received nintedanib than among those who received placebo. Diarrhea was a common adverse event. (Funded by Boehringer Ingelheim; INBUILD ClinicalTrials.gov number, NCT02999178.)
