Executive Summary

Gaucher Disease is a rare, inherited genetic disorder that is caused by the deficiency of an enzyme called glucocerebrosidase. This enzyme is responsible for breaking down a fatty substance called glucocerebroside within the cells, especially in the liver, spleen, bone marrow, and nervous system. When this enzyme is deficient or dysfunctional, glucocerebroside accumulates inside the lysosomes (the cell's waste disposal units), leading to cell damage and resulting in the symptoms associated with Gaucher disease.

The most significant unmet need in the Gaucher disease treatment landscape is to address the neurological complications of Type 2 and Type 3 Gaucher disease. While enzyme replacement therapy (ERT) effectively manages organomegaly (enlarged spleen and liver) and hematological symptoms, it does not treat neurological symptoms such as seizures, cognitive decline and motor dysfunction seen in Type 2 and 3 patients.

The development of neuronopathic treatments is a key focus in the pipeline, with gene therapies, substrate reduction therapies (SRT) and new enzyme replacement therapies being explored. For instance, AVR-RD-02, an investigational hematopoietic stem cell (HSC) gene therapy being evaluated for the treatment of Gaucher disease type 1 (GD1), has demonstrated efficacy and safety in interim data from the phase 1/2 Guard1 clinical trial. Its success in clinical trials could significantly increase demand for advanced gene therapy options, driving market growth.

List of Key Companies

The major and key players in the Gaucher disease pipeline include

• CANbridge Life Sciences Ltd.

CAN103: CAN103, a product of CANbridge's collaboration with WuXi Biologics, is the first enzyme replacement therapy (ERT) being developed for Gaucher disease (GD) in China. CAN103 is intended for the long-term treatment of adults and children with GD Types I and III.

• Spur Therapeutics

FLT201: FLT201, investigational gene therapy for the treatment of GD1, is a novel, proprietary, liver-tropic capsid (AAVS3) with a unique GBA1-85 transgene encoding an engineered variant of B-glucocerebrosidase (GCase85) that provides extended stability in serum and at lysosomal pH compared to wild type GCase, allowing for greater residence time and availability for use by tissues. Based on the data, Spur Therapeutics planning to move forward into a Phase 3 trial in 2025.

• Prevail Therapeutics
• Sanofi
• Lingyi Biotech Co., Ltd.
• Yuhan Corporation

Regulatory Designations

• In February 2025, Spur Therapeutics announced positive feedback from its end-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA), supporting its planned Phase 3 trial for FLT201, an adeno-associated virus (AAV) gene therapy candidate for Gaucher disease type 1. Lyso-Gb1 is one of the best predictors of clinical response in Gaucher disease, and FLT201 showed rapid and sustained reductions in lyso-Gb1 in its Phase 1/2 GALILEO-1 trial.
• In July 2024, Yuhan Corporation received approval for phase 1 clinical trial of Gaucher disease treatment from the Ministry of Food and Drug Safety for the Phase 1 clinical trial plan (IND) for 'YH35995,' a new drug being developed to treat Gaucher disease.

Merger and Acquisitions

• In August 2024, CANbridge Pharmaceuticals Inc. announced positive topline results from the CAN103 pivotal trial, in treatment-naive subjects aged 12 or above with Gaucher disease (GD) Types I and III. CAN103, a product of CANbridge's collaboration with WuXi Biologics (2269.HK), is the first enzyme replacement therapy (ERT) and is intended for the long-term treatment of adults and children with GD Types I and III.

Future Perspectives and Conclusion

The future perspectives for the Gaucher disease pipeline are highly optimistic due to significant advances in gene therapies, substrate reduction therapies (SRT) and enzyme replacement therapies (ERT). The evolving landscape is being shaped by several factors, including ongoing research, new drug development, clinical trials and regulatory advancements.

One of the most exciting areas in the Gaucher disease pipeline is the development of gene therapies. Traditional treatments, such as enzyme replacement therapy (ERT), have shown significant benefits in managing the symptomatic aspects of the disease, but they are limited in their ability to address neurological involvement, particularly in Type 2 and Type 3 Gaucher disease. Gene therapy involves delivering a functional copy of the defective gene responsible for Gaucher disease, GBA (glucocerebrosidase), to patients' cells, allowing them to produce the enzyme themselves. This approach could potentially offer long-term benefits for patients, reducing the need for lifelong enzyme infusions.

As clinical trials continue and data becomes more robust, gene therapy is expected to revolutionize Gaucher disease treatment, especially for Type 2 and Type 3 patients who have neurological involvement. The approval of gene therapies could significantly reduce treatment costs in the long term, and improve patient outcomes.
