About Us
Courage Therapeutics is a leading neuroendocrine company co-founded by Dr. Roger Cone, a pioneering researcher in melanocortin receptor biology and the central melanocortin system’s neural circuits that govern energy balance. We translate decades of Dr. Cone’s discoveries into therapeutic candidates targeting MC4R, the master regulator of appetite and body weight.
Our melanocortin agonists show single-agent activity across multiple forms of genetic obesity — populations that today have no or limited effective targeted therapy.
Our Focus
Our lead candidate, CTX-B, treats genetic obesity driven by deficiencies in the MC4R pathway, beginning with MC4R haploinsufficiency (MC4R HI) — a well-defined obesity characterized by early onset hyperphagia and obesity with no approved targeted therapeutic options.
MC4R Pathway
MC4R is the central regulator of hunger and body weight and is a major genetic driver of hyperphagia and severe obesity. MC4R pathway-driven obesity arises from mutations at multiple points — as far upstream, where defects impair leptin signaling and the production of pro-opiomelanocortin (POMC), the precursor of α-melanocyte-stimulating hormone (α-MSH), MC4R’s natural ligand; through to the MC4R itself. Mutations in between can impair the ability of POMC production.
Our agonists act directly on MC4R to compensate for the lack of adequate ligand expression or augmenting endogenous ligand levels to restore pathway activity and reduce the otherwise uncontrollable drive to eat.
CLINICAL CANDIDATE: CTX-B
CTX-B is a weekly injectable for the treatment of MC4R haploinsufficiency (MC4R HI). While we believe our drug can address the 250K+ patients in the US that have severe obesity caused by MC4R pathway mutations, we chose MC4R HI as our initial indication because of:
- the clinical need in this severely obese population;
- the absence of any therapy targeted to this particular segment of genetic obesity;
- and the size of the population - an estimated 100K–150K patients, roughly half of the genetic obesity population
In preclinical models of MC4R HI, CTX-B produces significant weight loss. In preliminary non-human primate studies, it showed no cardiovascular signal at supratherapeutic exposures — a liability that has caused suspension of certain earlier programs.
Beyond Genetic Obesity
The MC4R pathway also opens a path into common obesity. In animal models, our compounds combine with various incretin therapies to deepen weight loss while sparing lean muscle and delaying weight regain after discontinuation, thereby addressing key limitations of today’s GLP-1 medicines. Our compounds also show single agent activity in animal models of dietary obesity, offering an alternative therapy for the 25% of the general population that are unresponsive to incretins or cannot tolerate them. We view general obesity as a meaningful expansion opportunity beyond our core focus on genetic obesity.

Giovanni Ferrara, M.Sc., M.B.A.
CEO

Mr. Ferrara was most recently President and CEO of Medeor Therapeutics, Inc., a transplant immunology company where he completed the world’s first multi-center, international Phase 3 clinical study that successfully induced immunotolerance in transplant patients allowing them to eliminate the use of toxic immunosuppressive drugs. Prior to that, he was Founder, President and CEO of NeuroVia, Inc., a clinical stage orphan CNS disease company, where he raised a Series A financing, built an efficient team and established the clinical and regulatory strategy to lead the company into an efficacy study. Previously, he was an Entrepreneur-in-Residence at Novartis Venture Fund (NVF), where he founded NeuroVia in 2013 amongst his other activities as an operating partner. He joined NVF from portfolio company Sorbent Therapeutics where he was consulting Chief Business Officer, raising $58M in oversubscribed financing and led the refocusing of the company’s lead program. Prior roles include General Partner and Managing Director at Burrill & Company after starting his venture capital and business development career at GeneChem Management (including CEO of portfolio company Targanta Therapeutics) and BioChem Pharma. He received his MBA and MSc (molecular endocrinology) from McGill University.
Roger Cone, Ph.D.
Co-Founder

Roger Cone joined the University of Michigan in 2016 as the Director of the Life Sciences Institute, and was appointed Vice Provost for the Biosciences in 2017. Prior to Michigan, Cone was Professor and Chairman of the Department of Molecular Physiology and Biophysics at Vanderbilt University from 2008–2016. Cone is credited with the discovery of multiple fundamental biological roles for the melanocortin system in energy homeostasis. These findings resulted from studies cloning and characterizing the five receptors for the melanocortin peptides, and analyzing the pharmacological and physiological functions of these receptors. Cone’s group provided the genetic and pharmacological validation of the melanocortin-4 and melanocortin-3 receptors as critical regulators of energy homeostasis, leading to the discovery of mutations in the MC4R as the leading cause of syndromic obesity, and development of the first drug for syndromic obesity, the MC4R agonist Imcivree, approved by the FDA in 2020. Cone has been elected to the National Academy of Sciences (2010), and the National Academy of Medicine (2016) for his work, and received numerous awards, including the Berson Award, Berthold Memorial Award, Ipsen Prize, and the Rolf Luft Prize.
