SAN DIEGO, March 5, 2014 (GLOBE NEWSWIRE) -- Receptos, Inc. (Nasdaq: RCPT ) today provided development program updates and announced financial results for the fourth quarter and year ended December 31, 2013.

"The data from the interim analysis of the Phase 2 portion of our RADIANCE trial was consistent with our differentiation thesis, and provided support to continue to advance the program," said Faheem Hasnain, President and Chief Executive Officer of Receptos. "Our initiation of the Phase 3 portion of our RADIANCE trial positions RPC1063 as the potential next-to-market oral agent for the treatment of relapsing multiple sclerosis. We look forward to mid-2014 for the top-line results of the Phase 2 portion of RADIANCE, as well as top-line results of TOUCHSTONE, our Phase 2 study of RPC1063 in ulcerative colitis, and continued progress with our pipeline programs."

Receptos is developing RPC1063, a small molecule sphingosine 1-phosphate 1 (S1P1) receptor modulator administered orally for immunology indications. The Company has initiated a Phase 3 trial of RPC1063 in relapsing multiple sclerosis (RMS) and is currently conducting separate Phase 2 trials in RMS and ulcerative colitis (UC), with top-line data expected for both trials in mid-2014. The Company is also developing RPC4046, an anti-interleukin-13 (IL-13) antibody for an immune-mediated orphan disease, eosiniphilic esophagitis (EoE), and is in preclinical development of oral, small molecule, positive allosteric modulators of the GLP‑1 receptor for the treatment of Type 2 diabetes.

Development Program Updates

RPC1063 in Relapsing Multiple Sclerosis

• In Q4 2013, Receptos completed enrollment in the Phase 2 portion of RADIANCE, its Phase 2/3 trial of RPC1063 in RMS. The primary objective of the Phase 2 portion of the study is to demonstrate the superior clinical efficacy of RPC1063 compared to placebo as measured by a reduction in the cumulative number of total gadolinium-enhancing lesions determined by MRI from week 12 to week 24 of study treatment. Top-line data for this trial is expected in mid-2014. 
• In Q4 2013, Receptos completed a pre-planned interim analysis of the Phase 2 portion of RADIANCE. The interim analysis focused on several potential product attributes that may be important for differentiation from other S1P receptor modulators on the market or in development. These included the overall adverse event profile; cardiovascular profile; liver enzyme effects; and preliminary clinical activity and reduction in lymphocyte count.
• In December 2013, based on these interim results and with the recommendation of the study's Data Monitoring Committee, the Company initiated enrollment of the Phase 3 portion of RADIANCE. This is a randomized, double-blind, double-dummy study designed to compare 0.5 mg and 1.0 mg of orally administered RPC1063 against injected interferon beta-1a (Avonex®) in 1,200 patients with RMS. It is being conducted under a Special Protocol Assessment (SPA) with the FDA. 

RPC1063 in Ulcerative Colitis

• Receptos continues to enroll a randomized Phase 2 study (TOUCHSTONE) for the treatment of UC, a serious gastrointestinal disease. The primary objective of TOUCHSTONE is to demonstrate superior clinical efficacy of RPC1063 compared to placebo for the induction of clinical remission in patients with moderately to severely active UC after eight weeks of treatment. Top‑line results for this Phase 2 study continue to be anticipated in mid-2014.   

RPC4046 in Eosiniphilic Esophagitis

• Receptos is planning a Phase 2 proof‑of‑concept study in patients with active eosiniphilic esophagitis (EoE), a GI-related immunological indication that has a prevalence of under 200,000 patients in the U.S. and could qualify for orphan designation. The Company completed a pre-IND meeting with the FDA in Q4 2013 intends to file an IND with the Division of Gastroenterology of the FDA. Submission of an IND in the first half of 2014 would facilitate the initiation of a Phase 2 trial; a Phase 1 study has previously been completed.

Oral GLP-1 Receptor Positive Allosteric Modulator Program

• Receptos is pursuing a research program for glucagon-like peptide-1 receptor (GLP-1R) small molecule, positive allosteric modulators (PAMs) for the treatment of Type 2 diabetes.  Internally developed, orally administered lead compounds have shown single agent efficacy in a diabetic disease model as well as activity that is synergistic with metformin in combination studies. 

Key upcoming milestones

• Mid 2014: Top-line results of Phase 2 portion of RPC1063 (RADIANCE) in RMS patients
• Mid 2014 (subsequent to RADIANCE results): Top-line results of Phase 2 trial of RPC1063 (TOUCHSTONE) in UC patients
• 1H 2014: Filing of IND with GI division of FDA for RPC4046 in Eosiniphilic Esophagitis

Financial highlights for the three months and year ended December 31, 2013

Fourth quarter 2013 financial results (three months ended December 31, 2013)

• Net loss for the fourth quarter of 2013 was $15.2 million, or $0.86 per common share, compared to a net loss of $4.5 million, or $3.08 per common share, for the fourth quarter of 2012.
• Total revenues for the fourth quarter of 2013 were $773,000, compared to $3.8 million for the fourth quarter of 2012. Revenue during these periods consisted primarily of amortization of up-front fees and milestone payments, which are being recognized over the estimated period of performance, and research and development funding received from our collaborative arrangements.
• Total operating expenses for the fourth quarter of 2013 were $15.9 million, compared to $8.3 million for the fourth quarter of 2012. Operating expenses for the fourth quarter of 2013 include $1.3 million of stock compensation expense, compared to $74,000 of stock compensation expense for the fourth quarter of 2012.

The increase in R&D costs is primarily related to increased Phase 2 trial activity and Phase 3 start-up costs for our Phase 2/3 trial of RPC1063 in RMS, and commencement of the Phase 2 trial of RPC1063 in UC.
• General and administrative (G&A) expenses were $3.2 million for the fourth quarter of 2013 compared to $803,000 for the fourth quarter of 2012. The increase in G&A costs is primarily related to increased personnel costs, additional stock compensation expense and additional expenditures on outside services, including consulting costs, legal and accounting fees, market research and insurance.
