Cushing's Disease Overview

Cushing's disease is a rare but serious endocrine disorder caused by a pituitary tumor that triggers excessive cortisol production. It presents with a variety of symptoms such as weight gain, fatigue, mood disturbances, high blood pressure, and impaired glucose tolerance. Cushing's syndrome is responsible for 80–85% of hypercortisolism cases, with 75–80% of those linked to ACTH-producing pituitary adenomas. Without treatment, the 5-year survival rate is only about 50%, emphasizing the urgent need for effective therapies.

Diagnosing Cushing's disease is especially difficult because it is rare, shares symptoms with other disorders, and presents in various ways. Only 40–60% of patients have a detectable tumor on standard Magnetic Resonance Imaging (MRI), and the diagnosis is often delayed by an average of 7 years.

Cushing's Disease Epidemiology Segmentation

The Cushing's disease epidemiology section provides insights into the historical and current Cushing's disease patient pool and forecasted trends for the 7MM. It helps recognize the causes of current and forecasted patient trends by exploring numerous studies and views of key opinion leaders.

The Cushing's disease market report proffers epidemiological analysis for the study period 2020–2034 in the 7MM segmented into:

• Total Prevalent Cases of Cushing's Disease
• Total Diagnosed Prevalent Cases of Cushing's Disease
• Gender-Specific Diagnosed Prevalent Cases of Cushing's Disease
• Age-Specific Diagnosed Prevalent Cases of Cushing's Disease

Cushing's Disease Treatment Market 

The primary treatment for Cushing's disease is usually transsphenoidal surgery to remove the pituitary tumor, which often leads to remission. However, some patients may experience a recurrence. When surgery is unsuccessful or not an option, medical therapies are used to control cortisol levels.

Various medications are available for managing Cushing's disease, especially in cases where surgery is ineffective or not feasible. One such drug is KORLYM, developed by Corcept Therapeutics, approved for treating hyperglycemia in patients with Cushing's syndrome who also have Type 2 diabetes or glucose intolerance. In 2024, a generic version by Teva Pharmaceuticals entered the market, adding competition, and Corcept itself has released a generic version as well. Other approved options include SIGNIFOR and SIGNIFOR LAR, ISTURISA, and RECORLEV. In addition, off-label drugs like ketoconazole, metyrapone, cabergoline, mitotane, and etomidate are also used in the U.S., with some marketed in Europe by HRA Pharma.

SIGNIFOR (pasireotide), developed by Recordati, was the first drug specifically approved for Cushing's disease by the FDA in 2012, and also gained EU approval. Recordati also markets SIGNIFOR LAR, a long-acting injectable version approved by the FDA and Japan's PMDA in 2018. This formulation, administered intramuscularly once every four weeks, shares the same mechanism as SIGNIFOR but offers a different delivery route.

Recordati is recognized as a leading player in this therapeutic area. Another key product from the company is ISTURISA (osilodrostat), the first FDA-approved oral drug that inhibits cortisol production by targeting the enzyme 11β-hydroxylase (CYP11B1), which is involved in the final step of cortisol synthesis. Its oral administration makes it more convenient for patients compared to injectable therapies. ISTURISA is also being studied for pediatric use in an ongoing Phase II trial (NCT03708900).

RECORLEV, originally developed by Strongbridge Biopharma and later acquired by Xeris Pharmaceuticals, was approved by the FDA in 2021. It is indicated for adults with endogenous Cushing's syndrome who are not surgical candidates or did not achieve a cure through surgery. Unlike ISTURISA, RECORLEV works by inhibiting cortisol production at multiple points in the steroidogenesis pathway, offering a distinct mechanism of action.

Cushing's Disease Market Dynamics

The Cushing's disease market dynamics are expected to change in the coming years. Although Cushing's disease is generally considered a rare condition, growing awareness and recent advances in research suggest that diagnoses may rise in the future; despite a seemingly crowded market, many current hypercortisolism treatments fail to normalize cortisol levels effectively and pose significant side effects highlighting a substantial opportunity for innovation, especially given the limited therapies specifically targeting Cushing's disease and the potential of newer oral alternatives like ISTURISA and RECORLEV to offer greater flexibility compared to SC and intramuscular options such as SIGNIFOR and SIGNIFOR LAR.

Furthermore, potential therapies are being investigated for the treatment of Cushing's disease, and it is safe to predict that the treatment space will significantly impact the Cushing's disease market during the forecast period. Moreover, the anticipated introduction of emerging therapies with improved efficacy and a further improvement in the diagnosis rate are expected to drive the growth of the Cushing's disease market in the 7MM.

However, several factors may impede the growth of the Cushing's disease market. Due to non-specific guidelines and recommendations, patients with Cushing's disease often face suboptimal care, delayed diagnosis, and inconsistent treatment approaches, further compounded by the diagnostic complexity, frequent misdiagnosis, and symptom overlap with more common conditions, which leave many undiagnosed or untreated; while existing therapies such as ketoconazole and metyrapone approved in Europe based on limited retrospective data and used off-label in the US despite high costs are widely trusted and entrenched in clinical practice, posing a significant barrier to the adoption of emerging therapies.

Moreover, Cushing's disease treatment poses a significant economic burden and disrupts patients' overall well-being and QOL. Furthermore, the Cushing's disease market growth may be offset by failures and discontinuation of emerging therapies, unaffordable pricing, market access and reimbursement issues, and a shortage of healthcare specialists. In addition, the undiagnosed, unreported cases and the unawareness about the disease may also impact the Cushing's disease market growth.
