Ventyx Biosciences Announces Results from the Phase 2 Trial of VTX958 in Participants with Moderately to Severely Active Crohn's Disease
The Phase 2 trial of VTX958 in Crohn's disease did not meet its primary endpoint of change from baseline in mean CDAI score in either VTX958 dose group
Both VTX958 dose groups achieved nominal statistical significance on the key secondary endpoint of endoscopic response as measured by SES-CD
At this time, Ventyx does not anticipate conducting additional clinical trials of VTX958 with internal resources
SAN DIEGO, July 29, 2024 (GLOBE NEWSWIRE) -- Ventyx Biosciences, Inc. (NASDAQ:VTYX) ("Ventyx"), a clinical-stage biopharmaceutical company focused on advancing novel oral therapies that address a broad range of inflammatory diseases with significant unmet medical need, today announced results from the Phase 2 trial of its allosteric TYK2 inhibitor VTX958 in participants with moderately to severely active Crohn's disease.
The Phase 2 trial enrolled 109 participants randomized to one of two VTX958 doses (225 mg and 300 mg twice daily) or placebo for a 12-week induction treatment period, followed by a long-term extension period. The primary endpoint was the change in the mean Crohn's disease activity index (CDAI) score (a patient reported outcome) from baseline to Week 12. A key secondary endpoint in this trial was endoscopic response, defined as a 50% reduction in the simple endoscopic score for Crohn's disease (SES-CD).
The trial did not meet its primary endpoint of change in mean CDAI score from baseline to Week 12 due to a higher than anticipated placebo response.
A dose-dependent treatment effect was observed on the key secondary endpoint of endoscopic response, at both the 225 mg and 300 mg doses (nominal p-value <0.05 and <0.01, respectively). Endoscopic response, evaluated by centrally read endoscopy, is considered an objective outcome and a high priority treatment goal. Both doses of VTX958 also showed a greater magnitude of decrease compared to placebo in two key biomarkers of inflammation, C-reactive protein and fecal calprotectin. VTX958 was well tolerated in the Phase 2 trial. The overall safety profile was consistent with previously conducted trials of VTX958.
Based on these results, the Company intends to conduct further analyses of the data to better understand the discordance between symptomatic and endoscopic response data. At this time, Ventyx does not anticipate conducting additional clinical trials of VTX958 with internal resources.
The Company held cash, cash equivalents and marketable securities of $279.7M as of June 30, 2024, which we continue to believe are sufficient to fund planned operations into at least the second half of 2026.
