Hereditary Spastic Paraplegia Market Poised for Significant Growth with the Emergence of Gene Therapies | DelveInsight
DelveInsight’s “Hereditary Spastic Paraplegias Market Insights, Epidemiology, and Market Forecast-2032” report provides an in-depth understanding of the hereditary spastic paraplegias market size, including historical and forecasted epidemiology, current treatment approaches, and emerging therapies across the 7MM. The report details treatment practices, emerging drugs, market share of individual therapies, and forecasted market size from 2019 to 2032, offering valuable insights for stakeholders and decision-makers in the neurological disorders therapeutic landscape.
Hereditary spastic paraplegias represents a clinically and genetically heterogeneous group of neurodegenerative disorders characterized by progressive spasticity and weakness of the lower limbs due to axonal degeneration in the corticospinal tracts.
The hereditary spastic paraplegias market is expected to expand steadily across 7MM over the coming decade, with total revenues growing at a decent CAGR by 2032. The US has the the largest share of hereditary spastic paraplegias treatment market among 7MM, mainly due to the robust healthcare funding, widespread adoption of advanced neuroimaging and genetic testing platforms, and strong patient-advocacy efforts are accelerating diagnosis rates and driving uptake of both symptomatic and emerging disease-modifying therapies.

Furthermore, rising disease awareness, improved diagnostic reporting, and an acute unmet need for targeted therapies are prompting pharmaceutical and biotech companies to invest heavily in hereditary spastic paraplegias research and development.
The epidemiological data presented in the report indicate key trends in incidence, demographics, and the hereditary spastic paraplegias patient pool. Hereditary spastic paraplegias affect roughly 0.1 to 9.6 individuals per 100K globally, with the US reporting approximately 3 cases per 100K. Japan’s prevalence is lower at around 0.2 per 100K. Furthermore, improved genetic screening and neuroimaging have led to increased diagnosis rates across the 7MM, revealing more than 80 causative genes and suggesting that many cases were previously underrecognized.

The current hereditary spastic paraplegias therapeutic landscape is limited to symptomatic management, as no disease-modifying treatments are currently available. Treatment approaches focus primarily on reducing muscle spasticity, improving strength and gait, and addressing urinary symptoms. The therapeutic arsenal includes physical therapy, oral antispastic medications, such as Baclofen, Progabide, and Dalfampridine, botulinum toxin injections for focal spasticity, and surgical interventions such as intrathecal baclofen pump implantation in severe cases. However, these approaches fail to address the underlying neurodegeneration, highlighting the critical hereditary spastic paraplegias unmet need.
The hereditary spastic paraplegias pipeline has witnessed encouraging developments in recent years, with multiple therapeutic approaches under investigation. Gene therapy has emerged as a promising avenue, particularly for SPG4, the most prevalent form of autosomal dominant HSP. Collaborative research between UMass Chan Medical School and Drexel University, supported by the Cure SPG4 Foundation, is advancing AAV9-based gene therapy for SPG4, with positive initial results observed in preclinical models.
Strategic collaborations and licensing deals between academic institutions and industry players further strengthen the development landscape, suggesting a gradually shifting therapeutic paradigm from purely symptomatic management toward disease modification and personalized medicine in hereditary spastic paraplegias.
Recent advances in the hereditary spastic paraplegia therapeutic landscape have been driven primarily by precision gene-replacement strategies targeting AP-4 complex defects. In April 2025, the FDA granted IND clearance along with orphan drug and rare pediatric disease designations to BlackfinBio’s AAV-based BFB-101 for SPG47, clearing the way for a Phase 1/2 open-label intracerebroventricular study at Boston Children’s Hospital in up to five pediatric patients.

Despite these advances, significant challenges remain in the hereditary spastic paraplegia market, including diagnostic delays, genetic heterogeneity, and the complexity of developing therapies for rare disease populations. These factors have traditionally limited pharmaceutical interest in the hereditary spastic paraplegia therapeutic space, though the growing focus on rare diseases and advances in precision medicine are gradually shifting this landscape.
Looking ahead, the hereditary spastic paraplegia market is expected to witness continued growth driven by increasing disease awareness, improved genetic testing capabilities, and the potential approval of novel disease-modifying therapies. The integration of biomarkers for disease progression and treatment response will likely play a critical role in clinical trial design and therapeutic development. As research continues to uncover the molecular mechanisms underlying different hereditary spastic paraplegia subtypes, targeted approaches addressing specific pathophysiological pathways are anticipated to reshape the treatment paradigm and improve outcomes for patients with this progressive neurological disorder.
