DOP026 Sustained remission with vedolizumab in patients with moderately to severely active ulcerative colitis: a GEMINI 1 post hoc analysis of week 14 remitters
Notice bibliographique
Résumé
Background: Sustained remission is a key therapeutic goal in ulcerative colitis (UC). Vedolizumab (VDZ) was more effective than placebo as induction and maintenance therapy in patients (pts) with moderately to severely active UC in the GEMINI 1 study (NCT00783718). This post hoc analysis assessed sustained remission during the maintenance phase of GEMINI 1. Methods: Analyses included pts enrolled in GEMINI 1, who received 6 weeks (wks) of induction with placebo or VDZ and entered 46 wks of maintenance continuing placebo or VDZ, respectively; eligible pts could then enrol into an open-label extension (OLE) to receive VDZ every 4 wks. The primary aim was to assess sustained remission (remission at Wks 26, 38 and 52) in pts who achieved remission at Wk 14. Remission was defined as 1) clinical remission (partial Mayo Score [PMS] ≤2 points with no individual subscore >1 point) or 2) rectal bleeding subscore =0. For the analyses, pts who received VDZ maintenance, discontinued before Wk 52 and then entered the OLE had missing maintenance data imputed using OLE data. Results: In total, 620 pts received VDZ (Wk 6 responders and non-responders) and 149 received placebo throughout GEMINI 1. Patient characteristics were broadly similar between treatment groups. From Wk 4 onwards, a significantly higher proportion of pts receiving VDZ were in clinical remission versus placebo in the overall and anti-TNF-naïve populations; significance was achieved at Wk 26 in the anti-TNF failure population. At Wk 14, 203 (33%) pts receiving VDZ and 30 (20%) pts receiving placebo were in clinical remission based on PMS, and 293 (47%) pts receiving VDZ and 43 (29%) pts receiving placebo were in remission based on rectal bleeding subscore. Of pts in remission at Wk 14, the VDZ group had a higher proportion of pts with sustained remission versus placebo according to both PMS and rectal bleeding definitions (Table); significance was reached in both the overall and anti-TNF-naïve populations, and a similar nominal trend was observed in the anti-TNF failure population. Table 1. Patients with remission at Week 14 that was sustained for all visits at Weeks 26, 38 and 52 Conclusions: Wk 6 is most likely too early to ascertain the full clinical benefit of VDZ. VDZ showed a significant difference versus placebo in the proportion of pts achieving clinical remission as early as Wk 4 for the overall and anti-TNF naïve populations. However, as per label, assessment of the clinical benefit should be made after 10–14 wks. In pts with remission at Wk 14 in GEMINI 1, continued VDZ treatment resulted in ∼60% of pts maintaining sustained remission based on PMS and rectal bleeding subscore.

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.
