Gaucher's Disease - Market Insight, Epidemiology, and Market Forecast - 2034

Key Highlights:

• Gaucher Disease is a rare inherited lysosomal disorder caused by mutations in the GBA1 gene, leading to deficiency of the enzyme glucocerebrosidase. This results in the accumulation of glucosylceramide (Gb1) and glucosylsphingosine (Lyso-Gb1) in cells, causing enlargement of the liver and spleen, anemia, low platelets, and in some cases, neurological involvement.
• Gaucher disease is a rare disease, with an incidence varying between 0.4 and 5.8 per 100 000 inhabitants. Its average prevalence is around 1/60 000 in the general population.
• Gaucher disease Type 1 accounted around 60% of all the type-specific cases in the United States in 2024.
• Current standard treatment options include enzyme replacement therapy (ERT) and substrate reduction therapy (SRT). Although these methods have shown good therapeutic effects, they still have obvious drawbacks.
• CEREZYME (imiglucerase), VPRIV (velaglucerase alfa), and ELELYSO (taliglucerase alfa) are approved ERT for the long-term treatment of Type 1 Gaucher disease. Additional approved therapies include CERDELGA (eliglustat) and ZAVESCA (miglustat) which are SRT therapy. Among these, CERDELGA is the only SRT approved in Japan specifically for Gaucher disease.
• The emerging pipeline for Gaucher disease includes Venglustat (Sanofi), GBA1 Gene Therapy (Eli Lilly), FLT201 (Spur Therapeutics), and others.
• In October 2024, Spur Therapeutics announced results from GALILEO-1, a first-in-human clinical trial of FLT201 gene therapy in patients with Gaucher disease Type 1 showing rapid and sustained improvements in glucosylsphingosine (lyso-Gb1), one of the best predictors of clinical response in Gaucher disease as well as improvement or maintenance of blood counts, organ volume and bone marrow burden in patients treated with a single infusion of FLT201.

Gaucher Disease Understanding and Treatment Algorithm

Gaucher Disease Overview

Gaucher disease, also known as Gaucher's disease is a rare inherited disorder caused by mutations in the GBA gene, resulting in deficient activity of the enzyme glucocerebrosidase. This leads to the accumulation of glucocerebroside and glucosylsphingosine (Lyso-Gb1) in cells of the liver, spleen, and bone marrow. It is an autosomal recessive disorder, meaning a person must inherit defective genes from both parents. Further, it is classified into three types that include Type 1 (non-neuronopathic), the most common, presents with organ enlargement, bone pain, and blood abnormalities; Type 2 (acute neuronopathic) is a severe infantile form with rapid neurological decline; and Type 3 (chronic neuronopathic) involves both systemic and progressive neurological symptoms.

The common symptoms of Gaucher disease include an enlarged liver and spleen, bone pain and fractures, easy bruising or bleeding, and fatigue due to anemia. Neurological symptoms, especially in Types 2 and 3, can include seizures, eye movement disorders, and cognitive difficulties.

Gaucher Disease Diagnosis

The diagnosis of Gaucher disease involves a combination of clinical evaluation, blood tests, imaging tests, genetic screening, and enzyme assays. The primary diagnostic tool is a blood test measuring glucocerebrosidase enzyme activity, commonly performed using the beta-glucosidase leukocyte (BGL) assay, which reveals significantly reduced enzyme levels in affected individuals. Genetic testing is often performed subsequently to identify mutations in the GBA gene, which helps confirm the diagnosis and detect carriers. Furthermore, imaging techniques such as Magnetic Resonance Imaging (MRI) or ultrasound to assess organ enlargement (liver and spleen) and bone involvement, as well as X-rays to evaluate bone disease. These diagnostic tools may support the diagnosis and help monitor disease severity and treatment response.

Gaucher Disease Treatment

The treatment of Gaucher disease aims to manage symptoms, offer supportive care, and improve the patient's quality of life. The disease is primarily treated by enzyme replacement therapy (ERT) or substrate reduction therapy (SRT). These therapies used for improving the symptoms, prevention of irreversible complications such therapies used for improving the symptoms, prevention of irreversible complications such as massive fibrous splenomegaly secondary osteoarthritis, vertebral compression, and other fractures, hepatic fibrosis and lung fibrosis, and improving overall health and quality of life of patients with Gaucher Disease. The symptomatic treatment options include various pain reduction therapies, blood transfusions, orthopedic surgery for bone and joints, and rare splenectomy. Splenectomy increases the risk of developing infection, thrombosis, or neoplasia.

Gaucher Disease Epidemiology

• Gaucher disease is a rare disease, with an incidence varying between 0.4 and 5.8 per 100 000 inhabitants. Its average prevalence is around 1/60 000 in the general population.
• Gaucher disease type 3 accounts for about 5% of all cases of Gaucher disease in European derived populations. Type 3 is a much more frequent variant in the Japan.
• According to NORD, there are approximately 6,000 individuals with Gaucher disease in the United States.

VPRIV is manufactured using a human cell line with Shire's proprietary gene activation technology.

Emerging Drugs

Venglustat (Ibiglustat; SAR402671): Sanofi

Venglustat, a small-molecule glucosylceramide synthase (GCS) inhibitor. Sanofi acquired Genzyme in 2011, marking a strategic collaboration to strengthen its rare disease portfolio. The drug has been granted Orphan drug designation in the US, Europe, and Japan for Gaucher disease type 3.

• Currently, the drug is beimg evaluated in Phase III clinical stage of development for the treatment of Gaucher Disease Type 3. Venglustat is also being investigated in combination with imiglucerase in adult patients with Gaucher Disease Type 3 in Phase II trial.
• In April 2025, the company announced that it expects to receive Phase III data for Type 3 Gaucher disease in the second half of 2025. This data is anticipated to support a planned regulatory submission in 2026.

PR001 (LY3884961; GBA1 Gene Therapy): Eli Lilly

PR001 is a gene-replacement therapy using adeno-associated virus 9 (AAV9) to deliver a functional copy of the GBA1 gene to the brain. A clinical Phase I/II Trial (PROCEED) of PR001 in patients with peripheral manifestations of Gaucher Disease is currently ongoing.

In October 2020, the US FDA granted Fast Track designation to PR001 for treating neuronopathic Gaucher disease (nGD).

Drug Class Insights

Glucosylceramide synthase (GCS) inhibitor

GCS inhibitors are a class of small molecules that are used in substrate reduction therapy (SRT) for Gaucher disease. These inhibitors target and block the enzyme glucosylceramide synthase, which is responsible for synthesizing glucosylceramide from ceramide and UDP-glucose. In individuals with Gaucher disease, a deficiency in the enzyme glucocerebrosidase results in the pathological accumulation of glucosylceramide within lysosomes. By reducing the synthesis of this substrate, GCS inhibitors help to prevent lipid accumulation and alleviate systemic symptoms. Furthermore, brain-penetrant inhibitors offer the potential to address neurological involvement in neuronopathic forms of the disease.

Gaucher Disease Market Outlook

The treatment of Gaucher Disease is personalized to each patient due to differences in symptoms, severity, and progression. It aims at reducing the symptoms and preventing permanent damage to the body using ERT and SRT. The ERT is a standard treatment for Gaucher disease, especially Type 1, where patients receive intravenous infusions of the missing enzyme glucocerebrosidase to reduce harmful substrate buildup. ERT effectively improves symptoms like enlarged spleen and liver, anemia, and bone complications. Currently, CEREZYME, VPRIV, and ELELYSO are approved ERT for the long-term treatment of Type 1 Gaucher disease.

SRT is an oral treatment for Gaucher disease that works by reducing the production of glucocerebroside, the fatty substance that accumulates due to enzyme deficiency. Unlike enzyme replacement therapy, SRT does not replace the missing enzyme but instead limits the substrate buildup. The two FDA-approved SRT for Gaucher disease are CERDELGA and ZAVESCA.

The treatment landscape for Gaucher disease is expected to advance significantly, with several innovative therapies currently in development, including Venglustat (Sanofi), PR001 (Eli Lilly), FLT201 (Spur Therapeutics), and others. These pipeline therapies have the potential to significantly transform the treatment landscape of Gaucher disease and market dynamics in the coming years.
