Hypothalamic Obesity Market

Key Highlights

• Hypothalamic obesity is a complex condition often resulting from hypothalamic damage due to brain tumors, surgery, radiotherapy, head trauma, or genetic defects.
• Signs and symptoms of hypothalamic obesity include excessive appetite, inability to feel ‘full’, rapid weight gain, daytime sleepiness, disturbed circadian rhythm, imbalances in the regulation of thirst, body temperature, heart rate, and/or blood pressure, and others.
• The conventional treatments for hypothalamic obesity are a calorie-restricted diet, exercise therapy, or pharmacologic treatment, but there is no effective treatment for hypothalamic obesity. Pharmacotherapy focuses on alterations in the efferent pathways. The generally used off label therapies are sympathomimetic appetite suppressants, leptin-sensitizing drugs, hormone replacement therapy, stimulants, GLP-1 agonist, and others. 
• With a better understanding of the disease, significant advancements are being made in the treatment of hypothalamic obesity. For instance, in January 2024, Rhythm Pharmaceuticals announced the completion of screening for enrollment in a pivotal Phase III clinical trial evaluating setmelanotide in patients with acquired hypothalamic obesity. Rhythm has closed screening and expects to over-enroll the trial, with more than 140 patients consented and undergoing active screening and baseline assessments.
• In January 2024, Rhythm Pharmaceuticals announced a global licensing agreement with LG Chem for LB54640, an investigational oral small molecule melanocortin-4 receptor (MC4R) agonist currently in Phase II clinical trials. This collaboration marks a key effort by pharmaceutical companies to advance treatments for hypothalamic obesity.
• However, there is an urgent need for further clinical development to combat the prevalence of hypothalamic obesity.

Hypothalamic Obesity Overview, Country-Specific Treatment Guidelines and Diagnosis

Hypothalamic obesity is a rare condition caused by damage to the hypothalamus, the brain region responsible for regulating hunger and metabolism. This damage can result from tumors (such as craniopharyngiomas), brain injuries, or surgeries, leading to uncontrollable weight gain due to disrupted appetite control and energy balance. People with hypothalamic obesity often experience rapid weight gain, reduced energy expenditure, and resistance to traditional weight-loss methods.

Other Types of Obesity:

1. Obesity – A chronic condition characterized by excessive fat accumulation, increasing the risk of diabetes, heart disease, and other metabolic disorders. It is primarily influenced by lifestyle, genetics, and environmental factors.

2. Pediatric Obesity – Obesity in children and adolescents, often caused by poor diet, lack of physical activity, and genetic predisposition, leading to long-term health risks.

3. HET Obesity/POMC Deficiency Obesity – A rare genetic disorder caused by mutations in the POMC gene, leading to early-onset severe obesity due to impaired appetite regulation.

4. Pro-Opiomelanocortin (POMC) Deficiency Obesity & Leptin Receptor (LEPR) Deficiency Obesity – These conditions result from genetic mutations affecting appetite control, causing excessive hunger and severe, early-onset obesity.

5. Syndromic and Monogenic Obesity – Rare obesity types caused by single-gene mutations or genetic syndromes (e.g., Prader-Willi Syndrome), often associated with developmental and metabolic abnormalities.

Hypothalamic Obesity Diagnosis

Diagnostic measures used to identify or evaluate hypothalamic obesity include physical exam evaluating anthropometric measurements and vital signs, health history, history of weight loss efforts, exercise, and eating habits, family history review. Laboratory tests are also done for potential complications of hypothalamic obesity, including fatty liver disease and obesity-related diabetes.

The hypothalamic obesity report provides an overview of hypothalamic obesity pathophysiology, diagnostic approaches, and detailed treatment algorithm along with a real-world scenario of a patient’s journey beginning from the first symptom, the time taken for diagnosis to the entire treatment process.

Further details related to country-based variations in diagnosis are provided in the report...

Hypothalamic Obesity Treatment

There are no FDA approved therapies specifically for hypothalamic obesity. Currently, treatment includes evaluation and treatment of the underlying condition and other health problems, as well as trying a variety of strategies to manage obesity, which unfortunately is often not responsive to treatment. Management of hypothalamic obesity is complex, and includes optimization of pituitary hormone replacement, nutrition (often, lower- or controlled carbohydrate approaches and/or portion control are trialed), physical activity and exercise, mental and behavioral health interventions and sometimes weight loss medications and/or or metabolic/bariatric surgery. Overall, aside from surgery, the benefits, if any, of the interventions are modest, and may not be experienced by all patients. Medications with some evidence for potential benefit in at least a sub-set of patients include stimulants, metformin, and glucagon-like peptide 1 receptor (GLP1R) agonists.

Hypothalamic Obesity Epidemiology

The hypothalamic obesity epidemiology chapter in the report provides historical as well as forecasted in the 7MM covering the United States, EU4 countries (Germany, France, Italy, and Spain), the United Kingdom, and Japan from 2024 to 2034. Hypothalamic obesity epidemiology is segmented with detailed insights into Total Prevalent Cases of Hypothalamic Obesity, Total Diagnosed Cases of Hypothalamic Obesity, Age-specific Prevalent Cases of Hypothalamic Obesity, Tumor-specific Prevalent Cases of Hypothalamic Obesity, and Hyperphagia associated Cases of Hypothalamic Obesity. 

• According to findings, in the United States, a variety of aetiologies causing hypothalamic obesity were reported out of which 86% of patients reported having developed hypothalamic obesity as a result of a brain tumor or tumor treated by surgery, with or without associated cranial radiation.
• According to findings, the estimated annual incidence of tumor/treatment-related hypothalamic obesity (TTR-HO) in Germany is between 0.7 and 1.7 cases per 1,000,000 persons. 
• This condition occurs across all age groups, with incidence peaks in children/young adults (ages 10-14) and adults (ages 40-44). 
• The most frequent hypothalamic obesity -validated tumor diagnoses are benign sellar/suprasellar tumors, including craniopharyngeal duct tumors, pituitary gland neoplasms, and nonspecific brain tumors of endocrine glands.

Hypothalamic Obesity Recent Developments

• In August 2025, Rhythm Pharmaceuticals, Inc. announced that the U.S. Food and Drug Administration (FDA) accepted for filing its supplemental New Drug Application (sNDA) for setmelanotide to treat conditions associated with acquired hypothalamic obesity. The FDA granted Priority Review with a PDUFA goal date of December 20, 2025.

Emerging Hypothalamic Obesity Drugs

IMCIVREE (setmelanotide): Rhythm Pharmaceuticals

IMCIVREE is a melanocortin 4 (MC4) receptor agonist indicated for chronic weight management in adult and Hypothalamic patients aged 6 years and older with monogenic or syndromic obesity. It is used specifically for those with obesity due to Pro-opiomelanocortin (POMC), proprotein convertase subtilisin/kexin type 1 (PCSK1), or leptin receptor (LEPR) deficiency, as determined by an FDA-approved test showing pathogenic, likely pathogenic, or uncertain significance (VUS) variants in the POMC, PCSK1, or LEPR genes. IMCIVREE is also indicated for patients with Bardet-Biedl syndrome (BBS).

LB54640 (LR19021): LG Chem/ Rhythm Pharmaceuticals

LB54640 is a first orally available, small molecule MC4R agonist. LB54640 has shown to be safe and well-tolerated in GLP toxicity studies. The efficacy and safety profiles of LB54640 observed in preclinical studies suggests that LB54640 can be a safe and effective drug for the patients with genetic obesity. The US FDA has granted Orphan Drug Designation for LB54640 for the treatment of leptin receptor deficiency obesity. Currently, LB54640 is being evaluated in a first-in-human study in healthy, non-diabetic, obese volunteers with body mass index ≥ 27 kg/m2 in the US.
