SAN DIEGO, Oct. 2, 2013 (GLOBE NEWSWIRE) -- Receptos Inc. (Nasdaq:RCPT) today announced that Company personnel will deliver two scientific poster presentations about RPC1063 at the annual meeting of the Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) in Copenhagen, Denmark during October 2-5, 2013. RPC1063 is the Company's lead sphingosine 1-phosphate 1 receptor (S1P1R) modulator in Phase 2 development for both relapsing multiple sclerosis (RMS) and inflammatory bowel disease (IBD).

The first Receptos poster presentation is titled "Results of a thorough QT/QTc (TQT) study of orally administered RPC1063, a novel, selective S1P1 receptor (S1P1R) agonist, in healthy adult volunteers." The data presented in the poster demonstrate that at steady state, therapeutic and supratherapeutic doses of RPC1063 had no adverse effect on cardiac repolarization as measured by the effects on Fridericia corrected QT interval (QTcF), ruling out a relevant effect of RPC1063 on QT interval. The dose titration regimen employed during the study appeared to attenuate first dose heart rate effects and was well tolerated throughout the titration period. No notable safety issues were identified.

The second Receptos poster presentation is titled "RPC1063, a potent and selective S1P1R modulator, has a favorable preclinical safety profile." The data presented in the poster demonstrate an encouraging preclinical safety profile for RPC1063, in which RPC1063 was well tolerated in animal toxicology studies up to 9 months in duration, with a wide margin of safety relative to estimated human therapeutic exposures. In addition, the absence of fibrotic changes is consistent with the selectivity of RPC1063 towards the S1P1R.

"We continue to build upon our clinical and preclinical experience with RPC1063 in RMS," said Faheem Hasnain, President and Chief Executive Officer of Receptos. "In particular, the lack of effect of RPC1063 on QT prolongation and the modest impact on heart rate appears to demonstrate a favorable cardiac safety profile."

About RPC1063 and S1P1R Modulators

RPC1063 is a novel, oral, once daily, selective and potent S1P1R modulator in development for autoimmune indications. Previously reported Phase 1 results demonstrated adequate pharmacokinetic, pharmacodynamic and safety features, which provide supportive data for the differentiation strategy for RPC1063 as a potential best-in-class second generation S1P1R modulator. Receptos is on track for enrollment completion in Q4 2013 in the randomized Phase 2 portion of a Phase 2/3 study called RADIANCE examining the efficacy, safety and tolerability of RPC1063 in RMS and is enrolling a randomized Phase 2 study called TOUCHSTONE examining the efficacy, safety and tolerability of RPC1063 in ulcerative colitis (UC). Top-line results for both studies are expected in mid-2014.
