Spruce Biosciences Secures Breakthrough Therapy Designation for Rare Disease Treatment

Summary

  • FDA grants Breakthrough Therapy Designation to Spruce Biosciences' enzyme replacement therapy for Sanfilippo Syndrome Type B
  • Therapy shows potential to normalize cerebral spinal fluid heparan sulfate, a key factor in neurodegeneration
  • Company maintains strong financial position with more cash than debt
Spruce Biosciences Secures Breakthrough Therapy Designation for Rare Disease Treatment

In a significant development, Spruce Biosciences, a small-cap biotech company, has announced that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation to its tralesinidase alfa enzyme replacement therapy (TA-ERT) for the treatment of Sanfilippo Syndrome Type B (MPS IIIB). This rare genetic disease is characterized by a deficiency in the enzyme required for the breakdown of heparan sulfate, leading to progressive neurodegeneration, cognitive impairment, and early death.

The Breakthrough Therapy Designation was supported by clinical data showing that TA-ERT was able to normalize cerebral spinal fluid heparan sulfate non-reducing end (CSF HS-NRE), a key pathogenic factor in the disease. The FDA has confirmed that this biomarker is reasonably likely to predict clinical benefit, potentially serving as a basis for accelerated approval.

Despite the company's stock experiencing significant volatility, with a beta of 2.48, InvestingPro analysis suggests that Spruce Biosciences' stock is currently trading below its Fair Value. The company maintains a strong financial position, with more cash than debt on its balance sheet and a healthy current ratio of 2.6, indicating its ability to meet short-term obligations.

In other recent news, Spruce Biosciences has announced that it will resume trading on the Nasdaq Capital Market, marking a significant step for the company as it re-engages with the public trading community.

TA-ERT is a fusion protein designed to restore enzyme activity in the central nervous system following intracerebroventricular injection, which has been evaluated in three clinical studies involving 22 participants with MPS IIIB.
The integrated group-level clinical data demonstrates a rapid, profound, and durable effect of TA-ERT in normalizing CSF HS-NRE, the pathogenic factor leading to neurodegeneration, and stabilizing cortical grey matter volume and cognitive function in children with MPS IIIB.
The company stated that its Biologics License Application submission for TA-ERT remains on track for the first quarter of 2026.
