Rhythm And Camurus Announce Positive Initial Data For Extended-Release Delivery Of Setmelanotide For The Treatment Of Rare Genetic Disorders Of Obesity
BOSTON and LUND, Sweden, June 27, 2017 /PRNewswire/ -- Rhythm and Camurus today announced positive initial results from an ongoing Phase 1A clinical trial evaluating the pharmacokinetics and tolerability of an extended-release formulation of setmelanotide (RM-493), Rhythm's novel melanocortin-4 receptor (MC4R) agonist in development for the treatment of rare genetic disorders of obesity. The new setmelanotide formulation uses Camurus drug delivery technology, FluidCrystal® injection depot. Camurus has granted Rhythm a worldwide license to the FluidCrystal® technology to formulate setmelanotide and to develop, manufacture, and commercialize this new formulation that has the potential for once-weekly dosing administered as a subcutaneous injection.
Rhythm is developing setmelanotide for the treatment of obesity caused by genetic deficiencies in the MC4 pathway, a key biological pathway in humans that regulates weight by increasing energy expenditure and reducing appetite. This ongoing Phase1A clinical trial is a double-blind, placebo-controlled, single-rising dose study to evaluate the pharmacokinetics and tolerability of three doses of setmelanotide extended-release formulation in healthy obese patients (BMI 30 kg/m2), with setmelanotide administered by subcutaneous injection.
"The initial results from this first trial are impressive and meet our pharmacokinetics and tolerability criteria for a once-weekly formulation of setmelanotide," said Dr. Keith Gottesdiener, Chief Executive Officer and Chairman of the Board of Directors of Rhythm. "We intend to develop this once-weekly formulation as a product line extension, to improve convenience for patients with genetic deficiencies in the MC4 pathway."
"Reducing the burden of daily injections, and thereby contributing to keeping the individual at a healthy weight, is an important step forward that may potentially provide patients with enhanced quality of life," said Dr. Fredrik Tiberg, President and Chief Executive Officer of Camurus.
The U.S. Food and Drug Administration (FDA) granted setmelanotide Breakthrough Therapy Designation (BTD) for the treatment of pro-opiomelanocortin (POMC) and leptin receptor (LepR) deficiency obesity. Results from Phase 2 clinical trials of setmelanotide demonstrated significant weight loss and substantial reductions in hunger for patients with POMC and LepR deficiency obesity. Rhythm recently initiated Phase 3 clinical trials for each of these indications.
Setmelanotide is a potent, first-in-class MC4R agonist in development for the treatment of obesity caused by genetic deficiencies in the MC4 pathwaya key biological pathway in humans that regulates weight by increasing energy expenditure and reducing appetite. The critical role of the MC4 pathway in weight regulation was validated with the discovery that single genetic defects along this pathway result in early-onset and severe obesity.
Rhythm recently initiated Phase 3 clinical trials of setmelanotide in POMC deficiency obesity and in LepR deficiency obesity. These are rare genetic disorders associated with severe, early-onset obesity and unrelenting hyperphagia caused by defects in the MC4 pathway that are upstream of MC4R. Initial efficacy data with setmelanotide demonstrate that it has the potential to restore lost function by activating the intact MC4 pathway below the genetic defect in these disorders. Rhythm is currently evaluating setmelanotide for the treatment of the following genetic disorders of obesity: POMC deficiency obesity, LepR deficiency obesity, Prader-Willi syndrome, Bardet-Biedl syndrome, Alström syndrome, POMC heterozygous deficiency obesity, and POMC epigenetic disorders.
About FluidCrystal® injection Depot
The FluidCrystal® injection depot delivers therapeutic levels of drug substance over selected extended periodsfrom days to monthsfrom a single injection. While traditional depot therapeutics comprise complicated microsphere technology, the FluidCrystal® injection depot offers a liquid solution that transforms into a controlled release liquid crystal gel matrix in situ on contact with minute quantities of aqueous fluid at the injection site. The FluidCrystal® delivery system overcomes traditional side effects associated with high initial drug release on injection (drug burst) and poor drug stability by effectively encapsulating the drug compound in the nanopores of the depot matrix throughout the entire process from injection until final degradation. This, together with the ready-to-use product design, makes the system highly suitable for sustained parenteral delivery of peptides and proteins. FluidCrystal® is a registered trademark of Camurus AB.
