Vitae Pharmaceuticals Announces Positive Top-Line Results From a Phase 1 Multiple Ascending Dose Trial of VTP-43742

  • Multiple ascending doses of VTP-43742 shown to be safe and generally well tolerated in healthy human volunteers
  • Robust ex vivo biomarker response, suppressing secretion of pro-inflammatory IL-17A by more than 90 percent
  • Top-line proof-of-concept clinical results from Phase 1 trial of VTP-43742 in psoriatic patients expected in the first quarter of 2016

FORT WASHINGTON, Pa., Nov. 18, 2015 (GLOBE NEWSWIRE) -- Vitae Pharmaceuticals, Inc. (NASDAQ:VTAE), a clinical-stage biotechnology company, today reported positive top-line results from the healthy human volunteer part of the multiple ascending dose Phase 1 clinical trial of VTP-43742. VTP-43742 is Vitae's wholly owned, orally active RORγt inhibitor with the potential to transform the treatment of multiple autoimmune disorders, including psoriasis, through the potent inhibition of IL-17 secretion from Th17 cells and blocking the action of IL-23.

In this double-blind, randomized, placebo-controlled trial examining the safety, tolerability, pharmacokinetic and pharmacodynamic profile of multiple oral doses of VTP-43742 in 40 healthy human volunteers, VTP-43742 was shown to be safe and generally well tolerated at all dose levels assessed. No serious adverse events were reported, and all study subjects completed the full 10 days of dosing. Vitae saw no drug-related clinical laboratory or electrocardiogram (ECG) abnormalities. Additionally, dose proportionality was demonstrated across all dose levels tested, and the half-life was consistent with once-a-day dosing.

In an ex vivo assay, VTP-43742 was also shown to suppress the RORγt dependent production of the pro-inflammatory cytokine IL-17A in blood obtained from study subjects. Those who received VTP-43742 showed a dose-dependent suppression of IL-17A production by more than 90 percent sustained for a full 24 hours in all but the lowest dose cohort. These results are consistent with the suppression of IL-17 production seen in Vitae's single ascending dose clinical trial of VTP-43742 in healthy human volunteers, for which results were disclosed in September 2015.

This clinical trial in healthy human volunteers is one part of Vitae's Phase 1 multiple ascending dose trial of VTP-43742. Top-line clinical efficacy results from the second part of the Phase 1 clinical trial, which is a proof-of-concept trial in patients with moderate to severe psoriasis, are expected in the first quarter of 2016.

"We continue to be very encouraged by the inhibition of IL-17 production that VTP-43742 has shown in our Phase 1 trials, along with its favorable safety and tolerability profile," said Dr. Richard Gregg, Chief Scientific Officer of Vitae. "These ex vivo results, combined with those seen in Vitae's previously disclosed single ascending dose trial, reaffirm our belief that VTP-43742's mechanism of action has the potential to safely and effectively treat psoriasis and an array of other autoimmune diseases. We look forward to obtaining top-line clinical proof-of-concept data from our trial in psoriasis patients in the first quarter of 2016."

Vitae's management team plans to discuss these top-line results from the healthy human volunteer part of the multiple ascending dose Phase 1 clinical trial of VTP-43742 and the development of the Company's other product candidates during an Analyst and Investor Briefing on Thursday, November 19, 2015 from 7:00 to 9:00 a.m. EST in New York, NY. Presentations will begin at 7:15 a.m. EST, and leading academic experts are scheduled to speak. For additional information and registration, please email vitae@westwicke.com or call 443-213-0506.

A live audio webcast of the event will be available via the "Investor Relations" page of the Vitae website, www.vitaepharma.com. Please log on through Vitae's website approximately 10 minutes before the scheduled start time. A replay of the webcast will be archived on Vitae's website for 90 days following the call.

About Psoriasis

Psoriasis, which affects approximately 7.5 million people in the U.S., is a chronic autoimmune disorder affecting the skin. It causes cells to rapidly multiply and build up on the skin's surface, resulting in red scaly patches that are often itchy and painful. Increased activity of a class of lymphocytes called Th17 cells, and the subsequent excess production of pro-inflammatory cytokines, including IL-17, by those cells are critical parts of the pathophysiology of psoriasis. RORγt is a nuclear hormone receptor that is essential for the formation and function of Th17 cells. Vitae believes that inhibiting RORγt activity in immune cells will be beneficial for the treatment of psoriasis, and potentially other autoimmune disorders.

About VTP-43742

VTP-43742 is Vitae's wholly owned, orally active RORγt inhibitor with the potential to transform the treatment of multiple autoimmune disorders, including psoriasis, through the potent inhibition of IL-17 secretion from Th17 cells and blocking the action of IL-23. In preclinical studies, VTP-43742 has been shown to inhibit RORγt activity, is highly selective versus other ROR isotypes, and has demonstrated potential for a human oral dosing schedule of once-a-day. The efficacy potential of VTP-43742 was demonstrated in an animal model of multiple sclerosis in direct comparison to an IL-17A monoclonal antibody. In September 2015, Vitae announced top-line results from a Phase 1 single ascending dose clinical trial in healthy human volunteers. Vitae also initiated an overlapping Phase 1 multiple ascending dose clinical trial in healthy human volunteers in August 2015, and in patients with moderate to severe psoriasis in September 2015.
