ENCINITAS, Calif., March 23, 2022 (GLOBE NEWSWIRE) — Ventyx Biosciences, Inc. (Nasdaq: VTYX), (“Ventyx”), a clinical-stage biopharmaceutical company focused on advancing novel oral therapies that address a range of inflammatory diseases with significant unmet medical need, today announced financial results for the full year ended December 31, 2021 and highlighted recent pipeline and business progress.

“I am proud of our team’s tremendous progress during 2021, including a successful IPO and significant advancements across our pipeline of novel small molecule clinical candidates,” said Raju Mohan, Chief Executive Officer. “2022 is shaping up to be a transformative year for Ventyx, with our current pipeline of three clinical-stage programs targeting TYK2, S1P1R and NLRP3. The Phase 2 ulcerative colitis trial for our S1P1R modulator VTX002 is currently enrolling. We anticipate data readouts from our Phase 1 trial for VTX958 early in the third quarter of 2022 and Phase 1 trial for our lead NLRP3 inhibitor VTX2735 in the second quarter of 2022. We believe VTX958 has potential to be a best-in-class allosteric TYK2 inhibitor, with development opportunities in multiple immune-mediated diseases encompassing large markets currently dominated by biologics. We plan to initiate Phase 2 trials with VTX958 in psoriasis, Crohn’s disease and psoriatic arthritis in the second half of 2022.”

Recent Corporate Highlights

• In December 2021, we announced dosing of the first patient in a Phase 2, randomized, placebo-controlled trial for VTX002, a novel oral S1P1R modulator, in patients with moderate-to-severe active UC.
• During the fourth quarter of 2021, we initiated dosing in a Phase 1 multiple-ascending dose (MAD) trial for our selective TYK2 inhibitor VTX958 and a Phase 1 trial for VTX2735, an oral, peripherally restricted NLRP3 inhibitor.
• We nominated VTX3232, a novel CNS-penetrant NLRP3 inhibitor, as a development candidate entering IND-enabling studies, with therapeutic potential across a range of neurodegenerative diseases, including Alzheimer’s disease, Parkinson’s disease, amyotrophic lateral sclerosis (ALS) and multiple sclerosis (MS).
• In October 2021, we completed an upsized initial public offering generating net proceeds of approximately $158.8 million, including full exercise of the underwriters’ option to purchase additional shares.
• We expanded our Scientific Advisory Board with the recent appointments of Richard Blumberg, MD, Manoj Desai, PhD and Ariel Feldstein, MD.

Pipeline Update

• VTX958 (TYK2 Inhibitor): VTX958 is an allosteric TYK2 inhibitor with high selectivity for TYK2 without any measurable inhibition of other JAK isoforms. We believe VTX958 has the potential to address a broad range of immune-mediated diseases, such as psoriasis, psoriatic arthritis, Crohn’s disease and lupus, each of which represents a substantial commercial opportunity to address large markets currently dominated by biologic therapies.

  We have completed the single-ascending dose (SAD) Phase 1 trial for VTX958 and initiated the MAD trial in healthy volunteers during the fourth quarter of 2021. We expect to complete dosing of the last subject in the second quarter of 2022 and plan to provide a clinical update early in the third quarter of 2022. We expect to provide a summary of safety, exposure and target engagement at this time, which we believe may support the differentiated profile of VTX958. We plan to advance VTX958 into Phase 2 trials in psoriasis, Crohn’s disease and psoriatic arthritis beginning in the second half of 2022.

• VTX002 (S1P1R Modulator): We are developing VTX002, a potentially best-in-class oral, S1P1R modulator, for patients with moderate-to-severe active UC. S1P1R is a clinically validated target with class efficacy established in UC and MS. In our Phase 1 trial, VTX002 was well tolerated across all doses tested while producing robust, dose-dependent reductions in circulating lymphocytes, a key biomarker of S1P1R modulator activity which has correlated with efficacy in multiple Phase 2 and Phase 3 trials of other S1P1R modulators. We initiated a Phase 2 randomized, placebo-controlled trial for VTX002 in patients with moderate-to-severe active UC during the fourth quarter of 2021. Enrollment in the trial is progressing and we expect to report topline data in 2023. We believe that this ongoing Phase 2 trial may serve as the first of two pivotal trials required for registration in UC.
• VTX2735 (Peripheral NLRP3 Inhibitor): Our oral, selective and peripherally restricted NLRP3 inhibitor VTX2735 is designed to target systemic inflammatory diseases, such as cardiovascular, hepatic, renal and rheumatologic diseases. We initiated a Phase 1 trial for VTX2735 in healthy volunteers during the fourth quarter of 2021. We expect to report topline data from this trial in the second quarter of 2022. Following completion of the ongoing Phase 1 trial, we intend to advance VTX2735 into one or more proof-of-concept trials in the second half of 2022.

• Expansion of the NLRP3 Portfolio with VTX3232: In the fourth quarter of 2021, we completed lead optimization activities and nominated VTX3232, our novel, oral CNS-penetrant NLRP3 inhibitor, as a development candidate. We expect to submit an IND for VTX3232 in the fourth quarter of 2022 with Phase 1 studies planned for the first quarter of 2023. We believe VTX3232 has potential to be the first CNS-penetrant NLRP3 inhibitor to enter the clinic and may provide therapeutic utility in a broad range of neurodegenerative diseases, including Alzheimer’s disease, Parkinson’s disease, ALS and MS.
