Tay-Sachs disease is a devastating and rare genetic disorder of the central nervous system (CNS). Caused by a deficiency of the enzyme hexosaminidase A (Hex-A), it leads to the accumulation of GM2 ganglioside in neurons, resulting in progressive neurological damage. Affecting approximately 1 in every 320,000 births in the United States, Tay-Sachs disease has become a critical focus in the field of rare disease therapeutics. The urgency to find effective treatments has driven numerous pharmaceutical and biotech companies to explore options such as enzyme replacement therapy (ERT), gene therapy, and substrate reduction therapy (SRT).

This article delves deep into the Tay Sachs disease drug pipeline, exploring the market size, dynamics, growth potential, challenges, key players, and latest developments in the pursuit of a cure.

Overview of Tay-Sachs Disease and Therapeutic Landscape

Tay-Sachs disease primarily affects infants and leads to severe neurological symptoms, including developmental regression, muscle weakness, vision and hearing loss, and seizures. The disease is typically fatal in early childhood, and currently, there is no approved cure check out Expert Market Research's Tay Sachs Disease Drug Pipeline Analysis report.

The therapeutic focus has increasingly turned to emerging biotechnologies, including:

• Enzyme replacement therapy (ERT) to restore deficient Hex-A levels.

• Gene therapy to deliver functional HEXA genes to cells.
