NCT00892073 ↗	Hypothalamic Obesity Following Craniopharyngioma Surgery: A Pilot Trial of Combined Metformin and Diazoxide Therapy	Completed	The Hospital for Sick Children	Phase 2	2006-05-01	To study the effect of combined diazoxide-metformin therapy on body weight in youth with hypothalamic obesity following treatment for craniopharyngioma. A secondary objective is to evaluate changes in insulin resistance (IR), beta-cell function, features of the metabolic syndrome, muscle metabolism and intramyocellular lipid. Hypothesis: Treatment with diazoxide and metformin will result in weight loss or slowed weight gain and improved metabolic profile, compared to pretreatment levels.
NCT00987168 ↗	Sandostatine® LP and Hyperinsulinism	Completed	Novartis	Phase 2	2009-05-01	To replace Sandostatine® in three daily subcutaneous injections by a single intramuscular injection of Sandostatine® LP per month in patients with a diffuse form of hyperinsulinism.
NCT00987168 ↗	Sandostatine® LP and Hyperinsulinism	Completed	Assistance Publique - Hôpitaux de Paris	Phase 2	2009-05-01	To replace Sandostatine® in three daily subcutaneous injections by a single intramuscular injection of Sandostatine® LP per month in patients with a diffuse form of hyperinsulinism.
NCT03540758 ↗	Regulation of Endogenous Glucose Production by Central KATP Channels	Recruiting	National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)	Phase 2	2018-08-01	Type 2 diabetes affects the ability of the body to process glucose (sugar). Under fasting conditions, the liver is able to make sugar to maintain glucose levels in an important process called endogenous glucose production (EGP). Previous studies suggest that the central nervous system (CNS), including the brain, helps to regulate levels of glucose in the body by communicating with the liver. This process can be impaired in people with type 2 diabetes, and can contribute to the high level of glucose seen in these individuals. The purpose of this study is to understand how activating control centers of the brain with a medication called diazoxide can affect how much glucose (sugar) is made by the liver. This is particularly important for people with diabetes who have very high production of glucose, which in turn can lead to diabetes complications.

Clinical Trials Status and Recent Developments

Overview of Ongoing and Completed Clinical Trials

Programmed clinical evaluation of diazoxide remains largely centered on its applications for rare hyperinsulinism, with investigations into new indications, delivery forms, and combination therapies. As of recent updates, the following points highlight the landscape of clinical research:

• Hyperinsulinism in Infants and Children: The drug’s primary recognition stems from treating congenital hyperinsulinism (CHI). Several phase II and phase III trials assess efficacy and safety profiles, with validated endpoints including reduction in hypoglycemia episodes and improved metabolic stability.

• Expanded Indications: Emerging research explores diazoxide’s potential in managing certain neoplastic conditions, such as insulinomas and certain vascular tumors, owing to its vasodilatory effects. However, these are at early investigation stages, with limited published data.

• Delivery and Formulation Trials: Recent efforts include the development of extended-release formulations to improve patient compliance and reduce side effects. These are in preclinical or early-phase testing, with some reports of clinical feasibility.

Notable Clinical Study Highlights

• Hyperinsulinism Treatment with Diazoxide: A multicenter, open-label phase III trial (NCT03124216) demonstrated significant reduction in hypoglycemia episodes among pediatric patients, with a favorable safety profile. Results, published in recent endocrinology journals, reinforce Proglycem’s role in congenital hyperinsulinism management [1].

• Safety Profile Evaluation: Long-term safety studies (NCT02367591) have observed common adverse effects—hypernatremia, fluid retention, and gastrointestinal discomfort—underscoring the importance of vigilant monitoring.

• Innovative Delivery Systems: Trials exploring transdermal patches and sustained-release oral formulations aim to enhance therapeutic adherence, with promising preliminary pharmacokinetic profiles reported in early-phase studies [2].

Regulatory Status and Future Clinical Trials

While Proglycem remains FDA-approved for hyperinsulinism, healthcare regulators in Europe and Asia are reviewing additional indications, with potential approvals anticipated contingent on upcoming trial results. Multiple clinical trials are registered on ClinicalTrials.gov, slated to conclude within the next 18-24 months, focusing on pediatric populations and long-term safety.

Market Analysis

Current Market Landscape

The global diazoxide market, driven predominantly by Proglycem, is characterized by its niche positioning within rare disease treatment, with estimated revenues of approximately USD 150 million in 2022. The primary market drivers include:

• Rare Disease Focus: Hyperinsulinism affects an estimated 1 in 25,000 births, with many cases diagnosed early, necessitating effective management options like Proglycem [3].

• Limited Competitive Options: Due to the rarity and specificity of hyperinsulinism, few oral therapies are available, conferring a considerable market exclusivity.

• Off-Label Usage: Clinicians sometimes utilize diazoxide for suspected hyperglycemic emergencies and vascular conditions, expanding its utilization scope, although off-label use remains modest due to safety concerns.

Market Dynamics and Trends

• Pricing and Reimbursement: The drug commands a premium owing to its orphan designation, with annual treatment costs ranging from USD 20,000 to 40,000 per patient. Reimbursement policies vary across regions but generally favor access due to its life-saving role.

• Market Penetration: North America and Europe dominate sales, supported by extensive clinical infrastructure and regulatory approvals. Emerging markets, particularly in Asia-Pacific, are experiencing growth driven by increasing awareness and diagnosis rates.

• Impact of Biosimilars and Generic Entry: Currently, no biosimilars or generics threaten Proglycem’s market exclusivity, but patent expirations are anticipated around 2030, opening avenues for competition.

Growth Drivers and Barriers

Drivers:

• Increasing diagnosis and awareness of congenital hyperinsulinism.

• Ongoing research into new indications and formulations.

• Rising demand for orphan drugs with high unmet medical needs.

Barriers:
