BOSTON, March 12, 2018 (GLOBE NEWSWIRE) -- Rhythm Pharmaceuticals, Inc. (NASDAQ:RYTM), a biopharmaceutical company aimed at developing and commercializing therapies for the treatment of rare genetic disorders of obesity, today reported financial results and provided a business update for the fourth quarter and full year ended December 31, 2017.

“2017 was a year of remarkable achievement at Rhythm, marked by our maturation into a late-stage, publicly-traded company and advancements across our clinical program for setmelanotide in six monogenic MC4 pathway deficiencies,” said Keith Gottesdiener, M.D., Chief Executive Officer of Rhythm. “In addition to completing our upsized initial public offering in October, we initiated our first Phase 3 trial of setmelanotide in patients with POMC deficiency obesity and, more recently, initiated a second Phase 3 trial in patients with LEPR deficiency obesity. We are poised to build on this momentum in 2018, as we progress with our ongoing pivotal trials, initiate a third pivotal Phase 3 trial in Bardet-Biedl Syndrome (BBS), and read out initial data from our Phase 2 proof-of-concept study in Alström Syndrome, POMC epigenetic disorders and POMC heterozygous deficiency obesity. We believe setmelanotide has tremendous potential to address the unmet needs facing patients with rare genetic disorders of obesity and look forward to gaining further insights into its potential clinical benefit.”

Recent Business Highlights and Upcoming Milestones:

Setmelanotide – POMC Deficiency Obesity

Rhythm finalized the protocol for its ongoing pivotal Phase 3 clinical trial evaluating setmelanotide in POMC deficiency obesity. Following discussions with the U.S. Food and Drug Administration (FDA), the trial’s primary endpoint is the responder analysis and the first secondary endpoint is mean percentage change in weight.
Rhythm confirmed plans to file a New Drug Application (NDA) with the FDA based on one-year data from a cohort of 10 patients in its ongoing Phase 3 study. Rhythm expects to complete enrollment of the required 10 patients in the first half of 2018, to announce initial data from the trial in the first half of 2019, and subsequently to file an NDA. The FDA has granted Breakthrough Therapy Designation (BTD) and Orphan Drug Designation (ODD) for setmelanotide in POMC deficiency obesity.
Rhythm also announced plans to enroll supplemental patients who may not complete one year of treatment at the time of NDA filing, including patients between six and 11 years of age under the implementation of a pediatric amendment, to provide additional important data regarding the use of setmelanotide in people living with POMC deficiency obesity.

Setmelanotide – LEPR Deficiency Obesity

Rhythm achieved First Patient In (FPI) in its pivotal Phase 3 clinical trial evaluating setmelanotide in LEPR deficiency obesity. Clinical trial sites are open across North America and Europe, and enrollment is expected to be complete by the end of 2018. The FDA has granted BTD and ODD for setmelanotide in LEPR deficiency obesity.

Setmelanotide – Additional Development Efforts

Rhythm enrolled the first patients, with each of: Alström Syndrome, POMC epigenetic disorders, and POMC heterozygous deficiency obesity, in its ongoing Phase 2 proof-of-concept basket study evaluating setmelanotide for the treatment of patients with rare genetic disorders of obesity. Rhythm expects to announce initial data in each indication in the first half of 2018.
Rhythm announced the completion of a multi-dose study evaluating an extended-release, once-weekly formulation of setmelanotide. The formulation, which Rhythm is developing in collaboration with Camurus AB, demonstrated tolerability and pharmacokinetics that support further clinical development.
Rhythm presented preliminary data from its ongoing Phase 2 proof-of-concept study evaluating setmelanotide for the treatment of BBS at ObesityWeek 2017 in Washington, D.C. The data show that once daily subcutaneous injection of setmelanotide resulted in reductions in hunger score in five patients with BBS and substantial weight loss in four, and that treatment has been safe and well-tolerated. Rhythm expects to initiate a pivotal Phase 3 clinical trial evaluating setmelanotide in BBS in 2018.
New genetic epidemiological analyses will be presented in a late-breaking poster presentation at ENDO 2018. The poster is titled “Melanocortin-4 Receptor Pathway Dysfunction In Obese Patients: Prevalence Estimates Of LEPR, POMC, And PCSK1 Variants,” and will be presented on March 19, 2018 from 1:00-3:00pm CT in Chicago, IL.

Corporate:

In October 2017, Rhythm completed an upsized initial public offering of common stock at $17.00 per share, raising net proceeds of $125.7 million, after deducting underwriting discounts, commissions and offering expenses.

Fourth Quarter and Year End 2017 Financial Results:

Cash Position: As of December 31, 2017, cash, cash equivalents and short-term investments were $148.1 million, as compared to $10.5 million as of December 31, 2016. This increase was primarily due to net proceeds of $125.7 million from Rhythm’s initial public offering of stock, which was completed in October 2017, partially offset by cash used to fund operating activities for the year ended December 31, 2017.
R&D Expenses: R&D expenses were $6.7 million for the fourth quarter of 2017 and $22.9 million for the year ended December 31, 2017, as compared to $5.6 million for the fourth quarter of 2016 and $19.6 million for the year ended December 31, 2016. The year over year increase of $3.3 million was primarily due to increased enrollment in the Phase 3 clinical trial evaluating setmelanotide for the treatment of POMC deficiency obesity and preparations for the Phase 3 clinical trial of setmelanotide in LEPR deficiency obesity, as well as the initiation of additional new clinical trials in 2017 and other development activities associated with setmelanotide. Rhythm hired additional personnel in the clinical operations department at the end of 2016 and throughout 2017.
S,G&A Expenses: S,G&A expenses were $4.3 million for the fourth quarter of 2017 and $9.5 million for the year ended December 31, 2017, as compared to $2.7 million for the fourth quarter of 2016 and $6.3 million for the year ended December 31, 2016. The year over year increase of $3.2 million was primarily due to an increase in headcount in both the commercial and general and administrative departments, as well as increased professional and consulting fees associated with being a public company.
Net Loss: Net loss was $10.5 million for the fourth quarter of 2017 and $33.7 million for the year ended December 31, 2017, or a net loss per basic and diluted share of $0.41 and $2.83, respectively, as compared to a net loss of $8.4 million for the fourth quarter of 2016 and $25.9 million for the year ended December 31, 2016, or a net loss per basic and diluted share of $0.90 and $2.85, respectively.

Financial Guidance

Based on its current clinical development plans, Rhythm expects that its existing cash and cash equivalents and available-for-sale marketable securities will be sufficient for Rhythm to fund its operating expenses and capital expenditure requirements into the second half of 2019.
