Receptos, Inc. (Nasdaq:RCPT) today provided development program updates and announced financial results for the third quarter ended September 30, 2013.

"We continue to execute on our Phase 2 trials of RPC1063 in relapsing multiple sclerosis (RMS) and ulcerative colitis (UC)," said Faheem Hasnain, Chief Executive Officer of Receptos. "Having now completed enrollment in the RMS trial, our timeline for reporting top-line data in mid-2014 is maintained. In addition, we look forward to the interim review of the RMS trial later this quarter, which will gate our decision to initiate Phase 3 in the coming weeks."

Receptos is developing RPC1063, a sphingosine 1-phosphate 1 (S1P1) receptor small molecule modulator candidate, for immune indications. The Company is currently conducting separate Phase 2 trials in RMS and 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, eosinophilic 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

• Receptos has completed enrollment in the Phase 2 portion of an accelerated, randomized Phase 2/3 study (RADIANCE) for the treatment of RMS.
• The Company anticipates conducting an interim analysis of the Phase 2 portion of this study in the fourth quarter of 2013, the results of which will inform any decision to advance into Phase 3. Top-line results for this Phase 2 study continue to be expected in mid-2014. 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.
• The Company recently reviewed the results of its Phase 1 Thorough QT/QTc study in a poster presentation at the annual meeting of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS). The study ruled out a QTc effect for RPC1063 at both the therapeutic and the supra-therapeutic doses. The study also confirmed a modest heart rate effect, which was attenuated by the dose titration regimen that was utilized. 

RPC1063 in Ulcerative Colitis

• Receptos continues to enroll a randomized Phase 2 study (TOUCHSTONE) for the treatment of  UC, a serious gastrointestinal disease. Top‑line results for this Phase 2 study are anticipated in mid-2014. 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. 

RPC4046 in Eosinophilic Esophagitis

• Receptos is in the planning stages of a Phase 2 proof‑of‑concept study in patients with active eosinophilic 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. As part of the planned development program for RPC4046, the Company intends to transfer the previous IND to the Division of Gastroenterology of the FDA, and has scheduled a pre-IND meeting in the fourth quarter of 2013. Submission of an IND in the first half of 2014 would facilitate the initiation of a Phase 2 trial, as a Phase 1 study has previously been completed in another indication.

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. 

Financial highlights for the three and nine months ended September 30, 2013

Third quarter 2013 financial results (three months ended September 30, 2013)

• Net loss for the third quarter of 2013 was $15.6 million, or $0.88 per share, compared to a net loss of $6.0 million, or $4.44 per share, for the third quarter of 2012.
• Total revenues for the third quarter of 2013 were $1.1 million, compared to $1.8 million for the third 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 third quarter of 2013 were $16.6 million, compared to $7.8 million for the third quarter of 2012. Operating expenses for the third quarter of 2013 include $1.1 million of stock compensation expense, compared to $50,000 of stock compensation expense for the third quarter of 2012.
• Research and development ("R&D") expenses were $13.5 million for the third quarter of 2013 compared to $6.8 million for the third quarter of 2012. R&D expenses consist primarily of costs associated with the preclinical and clinical development of our product candidates. 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 $3.1 million for the third quarter of 2013 compared to $1.0 million for the third quarter of 2012. The increase in G&A costs is primarily related to increased personnel costs, additional stock compensation and additional expenditures on outside services, including consulting costs, legal fees and insurance. 

Year to date 2013 financial results (nine months ended September 30, 2013)

• Net loss attributable to common shareholders for 2013 was $35.1 million, or $3.54 per share, compared to a net loss of $13.3 million, or $10.71 per share, for 2012. 
• Total revenues for the first nine months of 2013 were $3.9 million compared to $4.8 million for the comparable period 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 first nine months of 2013 were $36.7 million compared to $18.1 million for the comparable period of 2012.  Operating expenses for the first nine months of 2013 include $1.7 million of stock compensation expense, compared to $0.1 million of stock compensation expense for the comparable period of 2012.
• R&D expenses were $31.0 million for the first nine months of 2013 compared to $15.4 million for the comparable period 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.
• G&A expenses were $5.7 million for the first nine months of 2013 compared to $2.6 million for the comparable period of 2012. The increase in G&A costs is primarily related to increased personnel costs, additional stock compensation and additional expenditures on outside services, including consulting costs, legal fees and insurance.
