DOP016 Efficacy and Safety of Risankizumab in Patients With Moderate to Severe Crohn's Disease With 3 Years of Treatment: Results From the FORTIFY Open-Label Long-Term Extension
Notice bibliographique
Résumé
Abstract Background The FORTIFY maintenance open-label extension (OLE) is an ongoing phase 3 substudy evaluating the long-term efficacy and safety of risankizumab (RZB), a p19 interleukin-23 inhibitor, in patients (pts) with moderate to severe Crohn’s disease (CD). Previously, we presented the 2-year (Y) results from the OLE assessed through MAR2023, at which time most pts had yet to complete the week (W) 152 visit. Here, we report the full 2Y results with all pts having completed the W152 study visit. Methods Pts completing 52W of RZB maintenance were eligible to enroll in the FORTIFY (NCT03105102) OLE1,2, during which pts received 180mg subcutaneous (SC) RZB every 8W (Q8W), starting at W56, except pts who previously received rescue therapy (details in Figure footnote) as they continued 360mg SC Q8W in the OLE. Pts with inadequate response (increased symptoms + objective marker of inflammation) during the OLE received rescue therapy and remained on 360mg SC through the end of the study. Efficacy (endpoint definitions in Figure footnote) was assessed through W152 of RZB treatment (2Y in the OLE) using as observed (AO) and nonresponder imputation (NRI) methods. Data before receiving rescue therapy and upon/after receiving rescue therapy in the OLE are presented separately. All enrolled pts were included in the safety analysis. Treatment-emergent adverse events (TEAEs) reported on/after the first dose in the OLE were summarized (cutoff date: 01MAR2024). Results In the OLE, 1148 pts received ≥1 dose of RZB. Prior to receiving rescue therapy (pt numbers in Figure footnote), efficacy rates (per AO data) remained stable from W56 to W152 (both doses) for stool frequency/abdominal pain score (SF/APS) clinical remission (180mg, 69.8% to 74.8%; 360mg, 46.6% to 61.8% (84/136) and per CD Activity Index (CDAI) clinical remission (180mg, 72.9% to 81.1%; 360mg, 54.5% to 72.0%, endoscopic response (180mg: 57.5% to 75.7%; 360mg: 40.7% to 66.0%), and endoscopic remission (180mg: 41.6% to 62.4%; 360mg: 24.7% to 43.8%) (Figure). Similar results were observed per NRI data. Pts who received rescue therapy in the OLE (180mg, n=147; 360mg, n=76) also demonstrated clinical and endoscopic improvements by W152, irrespective of RZB dose received prior to rescue. The profiles of TEAEs and AEs of special interest were consistent with RZB’s known safety profile (Table).3,4 Conclusion Durable clinical and endoscopic efficacy was observed with long-term RZB maintenance therapy in the FORTIFY OLE. Pts who received rescue therapy in the OLE also showed clinical and endoscopic improvements by W152. No new safety risks for RZB were identified, supporting its long-term use in treating CD.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
