4SC AG (Frankfurt, Prime Standard: VSC), a discovery and development company of targeted small molecule drugs for autoimmune diseases and cancer, today announced topline results from its randomised, double-blind, placebo-controlled Phase Iib clinical trial COMPONENT in RA. The trial compared vidofludimus, an oral inhibitor of DHODH and pro-inflammatory cytokines (including IL-17A and IL-17F as well as INF-gamma), in rheumatoid arthritis patients on methotrexate background therapy versus methotrexate monotherapy over a treatment period of 13 weeks.

ACR20 response improvement of the 35 mg vidofludimus group compared to placebo was statistically significant (p<0.05) at week 2 (16.7% vs. 6.9%) and week 8 (46.7% vs. 31.9%), however, vidofludimus missed the primary endpoint of significantly improving ACR20 response at week 13 (50.0% vs. 44.8%). Time to ACR20 response was significantly (p<0.05) shorter in the vidofludimus group compared to placebo (median 56 days vs. 92 days). The patient group treated with vidofludimus also reported higher ACR50 and ACR70 response rates compared to placebo at week 13.

ACR Efficacy Results at Week 13:

Treatment N ACR20 ACR50 ACR70
35 mg Vidofludimus 120 60 (50.0%) 31 (25.8%) 15 (12.5%)
Placebo 116 52 (44.8%) 20 (17.2%) 7 (6.0%)

*All patients were on stable doses of methotrexate throughout the trial
*Confirmatory analysis of the primary efficacy endpoint (ACR20) has been performed for all randomized and exposed patients with a minimum of efficacy data available, i.e., at least one post-baseline efficacy observation (full analysis set included 236 patients)

Overall, vidofludimus was safe and well tolerated. No obvious differences in the adverse event rate between the vidofludimus and placebo group were observed. In particular, there were no relevant increases of diarrhea, neutropenia, anemia, hypertension, cholesterol or liver enzyme levels. Only one serious adverse event was reported in the vidofludimus group which was judged as not being related to vidofludimus. No deaths occurred. These safety results are consistent with previous Phase IIa trial results in RA and inflammatory bowel disease (IBD) patients.

'Even though we did not reach the primary efficacy endpoint,' said Dr Ulrich Dauer, CEO of 4SC AG, 'it is important to note that vidofludimus demonstrated efficacy in certain secondary parameters and showed very good tolerability in RA patients. We will continue to evaluate the novel mechanism of action of vidofludimus and use this new data set as an opportunity to advance our partnering discussions. We will continue our efforts for this compound in IBD and potentially other autoimmune indications such as lupus and psoriasis. Our Phase IIa trial in IBD achieved an excellent response rate of 88.5% and met the primary endpoint, both in Crohn's disease and ulcerative colitis patients. We feel this indication addresses an area of high unmet medical need that continues to be commercially attractive to potential partners and warrants the further development of vidofludimus based on the promising trial results.'

About the COMPONENT study

The COMPONENT study is a randomised, double-blind, placebo-controlled, multi-centre, international Phase IIb study evaluating the efficacy of vidofludimus with methotrexate, compared to methotrexate alone, in rheumatoid arthritis (RA) patients. The primary endpoint of this study is the estimation of ACR20 at week 13, secondary endpoints are ACR50, ACR70, DAS28, safety parameters and pharmacokinetics. The trial enrolled 241 patients in two study arms across 28 sites in Poland, Romania, Bulgaria and Czech Republic. In the first study arm patients received 35mg of vidofludimus given orally once-daily plus methotrexate, in the second study arm patients received placebo plus methotrexate. The study duration was 13 weeks and eligible patients must have had active RA, have received weekly doses of MTX (10 25 mg/week) for a minimum of 3 months prior to Day 1 dosing, and have received a stable MTX dose for at least 6 weeks prior to Day 1 dosing.

More information about the COMPONENT study can be found on (Identifier NCT01010581).

About Vidofludimus

Vidofludimus is a novel, orally administered small molecule for the treatment of autoimmune disorders such as rheumatoid arthritis and inflammatory bowel disease. The therapeutic efficacy of vidofludimus is based on a dual principle. Vidofludimus inhibits the expression of selected pro-inflammatory cytokines, including interleukin-17 (IL-17A and IL-17F) and INF-gamma that have crucial pathogenic roles in a variety of autoimmune diseases. Vidofludimus also inhibits dihydroorotate dehydrogenase (DHODH), a key enzyme of the pyrimidine biosynthesis, thereby halting the proliferation of activated T and B cells which are involved in the pathology of autoimmune disorders. Vidofludimus has completed a successful Phase IIa trial in inflammatory bowel disease. In addition, various preclinical models demonstrate the application options of vidofludimus in further autoimmune indications such as lupus, psoriasis, multiple sclerosis and transplant rejection.
