Progress update of Vitae’s RORγt inhibitor program
  • Robust efficacy results achieved in multiple sclerosis mouse model with record-breaking speed
  • Vitae’s time from initiation of program to animal proof-of-principle with qualified lead has consistently been less than 18 months

FORT WASHINGTON, PA – June 4, 2013 – Vitae Pharmaceuticals, Inc., a clinical-stage biopharmaceutical company discovering and developing novel, small molecule, first- and bestin-class compounds, today announced that it has achieved animal proof-of-principle of one of its ROR gamma t (RORγt) inhibitor candidates in an experimental allergic encephalitis (EAE) mouse model of multiple sclerosis in only nine months, breaking the company’s previous record of 12 months. Vitae is studying its RORγt inhibitors for the treatment of a wide range of autoimmune disorders, including rheumatoid arthritis, psoriasis, steroid-resistant asthma and multiple sclerosis.

In the study, VTP-xx1 significantly reduced the severity of disease at both 10 mg/kg and 30 mg/kg oral doses. The compound demonstrated decreases in multiple cytokines/cytokine receptors in vivo, and a 50-70 percent decrease in mRNA levels of interleukin-17A (IL-17A), interleukin-17F (IL-17F) and the receptor for interleukin-23 (IL-23R). The compound was well tolerated at all doses.

“We are excited about these data as they show that Vitae’s discovery technology platform generates compounds that are safe and efficacious in a highly relevant animal model,” said Jeff Hatfield, CEO of Vitae. “Our RORγt program is a great example of Vitae’s ability to rapidly and consistently innovate against difficult targets in high-impact therapeutic categories.”

Vitae’s structure-based drug discovery approach has consistently demonstrated superior speed and performance. Time from program initiation to animal proof-of-principle with a qualified lead has been less than 18 months in each of Vitae’s programs with hard-to-drug targets. The company’s speed in its RORt program bests that of its LXR program for atherosclerosis, which achieved animal proof-of-principle in 12 months.

RORt inhibits the production of IL-17, a pro-inflammatory cytokine that is a key contributor to the pathogenesis of autoimmune inflammatory diseasessuch as psoriasis, rheumatoid arthritis, multiple sclerosis and asthma. Focusing on a small molecule solution, in just six months Vitae was able to design and synthesize compounds that solve the most critical discovery challenges including potency, isotype selectivity and PK.

“We look forward to advancing this program, which has the potential to be a first-in-class and best-in-class disease modifying agent for the treatment of autoimmune disease,” said Hatfield.
