We are a global, commercial-stage biopharmaceutical company dedicated to transforming the lives of patients and their families living with rare neuroendocrine diseases. We are focused on advancing our melanocortin-4 recptor (MC4R) agonists, including our lead asset, IMCIVREE® (setmelanotide), as a precision medicine designed to treat hyperphagia and severe obesity caused by rare MC4R pathway diseases. While obesity affects hundreds of millions of people worldwide, we are advancing developing therapies for a subset of individuals who have hyperphagia, a pathological hunger that leads to abnormal food-seeking behaviors, and severe obesity due to an impaired MC4R pathway, which may be caused by traumatic injury or genetic variants. The MC4R pathway is an endocrine pathway in the brain that is responsible for regulating hunger, caloric intake and energy expenditure, which consequently affect body weight. IMCIVREE, an MC4R agonist for which we hold worldwide rights, is the first-ever therapy developed for patients with certain rare diseases that is approved or authorized in the United States, European Union (EU), Great Britain, Canada and other countries and regions. IMCIVREE is approved by the U.S. Food and Drug Administration (FDA) for chronic weight management in adult and pediatric patients 6 years of age and older with monogenic or syndromic obesity due to: (i) proopiomelanocortin (POMC), proprotein convertase subtilisin/kexin type 1 (PCSK1) or leptin receptor (LEPR) deficiency as determined by an FDA-approved test demonstrating variants in POMC, PCSK1, or LEPR genes that are interpreted as pathogenic, likely pathogenic, or of uncertain significance (VUS); or (ii) Bardet-Biedl syndrome (BBS). The European Commission (EC) and Great Britain’s Medicines & Healthcare Products Regulatory Agency (MHRA) have authorized IMCIVREE for the treatment of obesity and the control of hunger associated with genetically confirmed BBS or genetically confirmed loss-of-function biallelic POMC, including PCSK1, deficiency or biallelic LEPR deficiency in adults and children 6 years of age and above. In addition to the United States and Canada, we have achieved market access for IMCIVREE for BBS or POMC and LEPR deficiencies, or both, in 14 countries outside the United States, and we continue to collaborate with authorities to achieve access in additional markets.

In addition to initial commercial efforts, we are advancing what we believe is the most comprehensive clinical research program ever initiated in MC4R pathway diseases, with multiple ongoing and planned clinical trials. Our MC4R pathway program is designed to expand the total number of patients who would benefit from setmelanotide therapy or our one of our new drug candidates, RM-718, which is designed to be a more selective MC4R agonist with weekly administration, or LB54640, an investigational oral small molecule MC4R agonist in Phase 2 clinical trials. With setmelanotide, we have completed enrollment in our Phase 3 trial in patients with hypothalamic obesity. Our Phase 3 EMANATE trial, comprised of four independent substudies evaluating setmelanotide in genetically caused MC4R pathway diseases, and our Phase 2 DAYBREAK trial evaluating setmelanotide in additional genetic indications, are ongoing. With RM-718, in March 2024 we initiated a Phase 1 in-human trials, including a multiple-ascending dose study in patients with hypothalamic obesity. In our recently completed Phase 3 pediatrics trial in 12 patients between the ages of 2 and younger than 6 with BBS or POMC or LEPR deficiency obesities, setmelanotide achieved the primary endpoint

In our recently completed Phase 3 pediatrics trial in 12 patients between the ages of 2 and younger than 6 with BBS or POMC or LEPR deficiency obesities, setmelanotide achieved the primary endpoint with a 3.04 mean reduction in BMI-Z score (a measure of body mass index deviations from what is considered normal) and 18.4 percent mean reduction in BMI. We are seeking regulatory approval in the United States to expand the label for IMCIVREE to treat patients as young as 2 years of age with these diseases based on these data.

We are leveraging what we believe is the largest known DNA database focused on obesity - with almost 80,000 sequencing samples as of December 31, 2023 - to improve the understanding, diagnosis and care of people living with severe obesity due to certain variants in genes associated with the MC4R pathway. Our sequencing-based epidemiology estimates show that each of these genetically-defined MC4R pathway deficiencies are considered rare diseases, according to established definitions based on patient populations. Our epidemiology estimates are approximately 4,600 to 7,500 for U.S. patients in initial FDA-approved indications, including obesity due to biallelic POMC, PCSK1 or LEPR deficiencies,

Up until recently, our operations have been limited primarily to conducting research and development activities for setmelanotide. To date, we have not generated sufficient cash flow from product sales and have financed our operations primarily through the proceeds received from the sales of common and preferred stock, royalty interest financing, asset sales, as well as capital contributions from the former parent company, Rhythm Holdings LLC. From August 2015 through August 2017, we raised aggregate net proceeds of $80.8 million through our issuance of series A preferred stock. Since our initial public offering, or IPO, on October 10, 2017 and our underwritten follow-on offerings through October 2022, we have raised aggregate net proceeds of approximately $791.5 million through the issuance of our common stock after deducting underwriting discounts, commissions and offering related transaction costs. We also received $100.0 million from the sale of our Rare Pediatric Disease Priority Review Voucher, or PRV, to Alexion Pharmaceuticals, Inc. in February 2021. In June 2022, we entered into the Revenue Interest Financing Agreement (“RIFA”), with entities managed by HealthCare Royalty Partners, collectively referred to as the Investors, and through December 31, 2023 have received cumulative proceeds of $96.7 million, net of certain transaction costs.

Following marketing authorizations in the EU and Great Britain, we are pursuing a country-by-country strategy to establish market access and reimbursement for IMCIVREE in several countries. During March 2022, we treated the first patients with IMCIVREE in France under the paid early access program and we treated the first patients with IMCIVREE in Germany during June 2022.

However, we may be unable to raise additional funds or enter into such other arrangements when needed on favorable terms, or at all.

We recorded our first sales of IMCIVREE in the United States in March 2021 and we made our first sales in France during March 2022 under the paid early access program. IMCIVREE was approval by the FDA and the EC in adult and pediatric patients six years of age and older with obesity due to BBS in June and September 2022, respectively. Following these approvals for BBS, we expect our sales of IMCIVREE will continue to grow as we identify and treat more patients with this disease and obtain reimbursement throughout the international markets in which we operate.

Previous wording

All of our inventory of IMCIVREE produced prior to FDA approval is available for commercial or clinical use. Most of the manufacturing costs have been recorded as research and development expenses in prior periods. Accordingly, the product cost component related to IMCIVREE included in cost of sales for the three months ended March 31, 2024 and 2023 was insignificant. We expect cost of sales to increase in 2024 as we continue to sell inventory that is produced after we began capitalizing manufacturing costs for IMCIVREE commercial inventory.

Our net loss adjusted for non-cash items also includes $92.4 million of acquired IPR&D assets, which are classified as investing activities. The change in operating assets and liabilities used net cash of approximately $2.2 million, primarily driven by net increases in prepaid expenses and other assets of $2.4 million and net decreases in accounts payable and accrued expenses of $1.3 million, offset by a net increase in long-term assets of $1.2 million and decreases in accounts receivable and inventory of $0.3 million.
