SAN DIEGO, November 6, 2023 (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 VTX958 in patients with moderate to severe plaque psoriasis and provided a corporate update.
“While the Phase 2 trial of VTX958 in plaque psoriasis met the primary and key secondary endpoints, we are disappointed by the magnitude of efficacy observed, despite having achieved target levels of drug exposure in the trial,” said Raju Mohan, Ph.D., Founder and Chief Executive Officer. “Although these results do not support further development of VTX958 in the highly competitive psoriasis and psoriatic arthritis indications, I want to thank the patients and investigators for their participation. I would also like to thank the Ventyx team for their diligence and dedication in executing these trials.”
The Phase 2 SERENITY trial of VTX958 was a 16-week, randomized, double-blind, placebo-controlled, dose-ranging trial evaluating the efficacy and safety of four oral doses of VTX958 (50 mg BID, 300 mg QD, 225 mg BID, and 300 mg BID) in patients with moderate to severe plaque psoriasis. The primary endpoint was the proportion of participants achieving a 75% reduction in the Psoriasis Area and Severity Index (PASI 75) at Week 16. Both high doses of VTX958 (225 mg BID and 300 mg BID) achieved statistical significance on the primary endpoint and all key secondary endpoints at Week 16. No drug-related serious adverse events were observed.
Although the trial achieved its primary endpoint, the magnitude of efficacy observed did not meet our internal target to support advancement of VTX958 in plaque psoriasis. Accordingly, we will terminate ongoing activities in the Phase 2 plaque psoriasis trial effective immediately. Based on these results, we have also elected to terminate the ongoing Phase 2 trial of VTX958 in psoriatic arthritis. The ongoing Phase 2 trial of VTX958 in Crohn’s disease will continue to enroll and we intend to conduct an interim efficacy analysis in the first quarter of 2024.
Additional Pipeline Updates
| • | VTX002 (S1P1R Modulator): In October 2023, we announced positive results from the Phase 2 trial of VTX002 in patients with moderately to severely active ulcerative colitis (UC). We believe these data establish VTX002 as a potential best-in-disease oral agent in UC based on its differentiated efficacy profile, including a high rate of complete endoscopic remission, and its potential best-in-class safety profile. We expect to provide an update on the open-label extension of the Phase 2 trial in the first quarter of 2024. |
| • | VTX2735 (Peripheral NLRP3 Inhibitor): We are evaluating VTX2735 in a Phase 2 trial in patients with familial cold autoinflammatory syndrome (FCAS). FCAS is the most common subset of cryopyrin-associated periodic syndrome (CAPS), a group of rare autoinflammatory conditions caused by gain-of-function mutations in the NLRP3 gene. Patient enrollment is progressing, and we expect to provide an update on the trial in the first quarter of 2024. |
| • | VTX3232 (CNS-penetrant NLRP3 Inhibitor): We are conducting a Phase 1 trial of VTX3232 in adult healthy volunteers. The trial is designed to characterize the safety, pharmacokinetics and pharmacodynamics of VTX3232 in blood, and will also measure drug concentration and target engagement in cerebral spinal fluid. We expect to provide an update on the Phase 1 trial in the first quarter of 2024. |
| • | Cash Position: Our cash, cash equivalents and marketable securities balance was $300.8M as of September 30, 2023. |
