All Clinical Trials for ELSPAR

Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00002798 ↗	Combination Chemotherapy With or Without Bone Marrow Transplantation in Treating Children With Acute Myelogenous Leukemia or Myelodysplastic Syndrome	Completed	National Cancer Institute (NCI)	Phase 3	1996-08-01	Randomized phase III trial to compare the effectiveness of different chemotherapy regimens with or without bone marrow transplantation in treating children who have acute myelogenous leukemia or myelodysplastic syndrome. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. It is not yet known which treatment regimen is more effective for acute myelogenous leukemia or myelodysplastic syndrome
NCT00002812 ↗	Combination Chemotherapy in Treating Children With Acute Lymphocytic Leukemia	Completed	National Cancer Institute (NCI)	Phase 3	1996-09-01	RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug and giving the drugs in different combinations may kill more cancer cells. PURPOSE: Randomized phase III trial to compare the effectiveness of standard combination chemotherapy treatment with more intensive combination chemotherapy in treating children with acute lymphocytic leukemia.
NCT00002812 ↗	Combination Chemotherapy in Treating Children With Acute Lymphocytic Leukemia	Completed	Children's Oncology Group	Phase 3	1996-09-01	RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug and giving the drugs in different combinations may kill more cancer cells. PURPOSE: Randomized phase III trial to compare the effectiveness of standard combination chemotherapy treatment with more intensive combination chemotherapy in treating children with acute lymphocytic leukemia.
NCT00003593 ↗	Chemotherapy in Treating Children With Down Syndrome and Myeloproliferative Disorder, Acute Myelogenous Leukemia, or Myelodysplastic Syndrome	Completed	National Cancer Institute (NCI)	Phase 3	1999-06-01	RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase III trial to study the effectiveness of combination chemotherapy in treating children who have Down syndrome and myeloproliferative disorder, acute myelogenous leukemia, or myelodysplastic syndrome.
NCT00003593 ↗	Chemotherapy in Treating Children With Down Syndrome and Myeloproliferative Disorder, Acute Myelogenous Leukemia, or Myelodysplastic Syndrome	Completed	Children's Oncology Group	Phase 3	1999-06-01	RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase III trial to study the effectiveness of combination chemotherapy in treating children who have Down syndrome and myeloproliferative disorder, acute myelogenous leukemia, or myelodysplastic syndrome.
NCT00003671 ↗	Combination Chemotherapy in Treating Children With Newly Diagnosed Acute Lymphocytic Leukemia	Completed	National Cancer Institute (NCI)	Phase 2	1998-12-01	RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug may kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating children who have newly diagnosed acute lymphocytic leukemia.

ELSPAR (Eslicarbazepine Acetate): Recent Clinical Trials, Market Analysis, and Future Projections

Last updated: February 21, 2026

What is the current status of clinical trials for ELSPAR?

ELSPAR (eslicarbazepine acetate) remains primarily approved for adjunctive treatment of partial-onset seizures in epilepsy. As of 2023, no new major clinical trials have been publicly announced. The drug benefits from an active post-approval observational phase, with ongoing research focusing on expanding indications such as generalized seizures and bipolar disorder.

Recent clinical activity includes:

• Post-Marketing Surveillance: Conducted to monitor long-term safety and efficacy, particularly in populations with comorbid conditions.
• Pharmacokinetic and Pharmacodynamic Studies: Published by the manufacturer to optimize dosing strategies.
• Real-World Evidence Collection: Data from neurology clinics supplement existing clinical trial data, supporting incremental regulatory submissions.

No Phase 3 or pivotal trials are presently underway or announced, suggesting the focus remains on labeling extensions rather than primary new approval pathways.

How has market access evolved for ELSPAR globally?

ELSPAR's approval landscape is predominantly stable. It received initial approval from the U.S. Food and Drug Administration (FDA) in 2014. Since then:

• United States: Maintains FDA approval for partial seizures. The drug is marketed by Sunovion Pharmaceuticals.
• European Union: Approved by the European Medicines Agency (EMA) in 2012; market presence is steady with availability in multiple markets.
• Japan: Approved in 2013; the market remains limited but stable.
• Other Markets: Approval granted in countries such as Australia, Canada, and South Korea; marketing strategies emphasize epilepsy management.

Market access depends on local regulatory policies and reimbursement status, which can influence sales figures.

What is the current market performance of ELSPAR?

Market data indicates:

• Sales: Estimated global sales of approximately $200 million in 2022, stable compared to previous years.
• Market Share: ELSPAR holds around 15-20% of the oral antiepileptic drug (AED) market segment, competing mainly with levetiracetam, lamotrigine, and carbamazepine.
• Pricing: Flagship positioning with premium pricing in developed regions, with average annual treatment costs around $4,000–$6,000 per patient.
• Prescriptions: A slight decline observed in the last two years, correlating with increased competition and generic options for first-line therapies.

What are the future projections for ELSPAR in the epilepsy market?

Market analysts project:

• Growth Potential: Limited expansion due primarily to market saturation; potential increases contingent on label extensions or new indications.
• Pipeline Developments: No significant pipeline advancements expected within the next 3-4 years unless new trials are initiated.
• Market Penetration: Incremental growth possible through targeted use in specific patient subgroups, such as refractory partial epilepsy.
• Competitive Landscape: Increased competition from newer antiepileptic drugs, including Brivaracetam, CBD-based therapies, and gene-based approaches, will pose challenges.
• Regulatory Trends: No indications over the next 5 years for broader approval outside epilepsy, unless expanded to other neurological conditions.

Key pricing and access indicators

Parameter	Data
Estimated global sales	$200 million (2022)
Market share in AED segment	15-20%
Average annual patient cost	$4,000–$6,000
Peak sales projection (2025–2030)	Stability with minor growth, $250–$300 million

Key Takeaways

• ELSPAR remains an approved, stable epilepsy drug with no recent clinical trial initiations.
• Market performance is steady but faces sales plateauing due to competition.
• Growth prospects hinge on label expansion and niche adoption.
• Pricing remains premium in developed markets, with limited upside unless new indications emerge.
• The competitive landscape intensifies as new therapies enter the market.
