NCT07227857
Study CL1-230815-001 (KANDLE) is a Phase Ib/II, First In Human, multicentre, open-label, multiple ascending dose study to assess the safety, tolerability, pharmacokinetics (PK) and pharmacodynamic (PD) effect of S230815 in pediatric participants with KCNT1-related Developmental Epileptic Encephalopathy. To participate in the study, participants must have a diagnosis of Developmental Epileptic Encephalopathy due to a documented pathogenic or likely pathogenic variant in KCNT1 (to be confirmed by central genetic testing at the screening visit). The study consists of a screening period followed by two consecutive interventional parts. Part 1 will evaluate multiple ascending doses of S230815. Part 2 is a long-term treatment extension for participants who have completed Part 1. Participants will seamlessly roll-over from Part 1 to Part 2, resuming the same cohort as they were assigned in Part 1, and will receive S230815 for a maximum of 72 weeks.
NCT07396883
This study focuses on children with Developmental and Epileptic Encephalopathy (DEE), a severe form of epilepsy that often has a genetic origin. Currently, standard diagnostic tools-known as short-read genome sequencing-fail to provide a diagnosis for over 50% of affected patients because they cannot detect certain complex DNA abnormalities. The purpose of this study is to evaluate the effectiveness of a newer, more advanced technology called Long-read Genome Sequencing (lrWGS). Unlike traditional methods, this technology analyzes very long fragments of DNA, allowing researchers to identify genetic errors that were previously "invisible." The study aims to answer whether Long-read Sequencing can successfully identify the genetic cause of epilepsy in patients who have already received a negative result from standard testing. By finding these missing answers, the research seeks to enable personalized medical treatments, improve genetic counseling for families, and advance our understanding of how these complex neurological conditions develop.
NCT06938542
The palliative care needs of family caregivers of children with rare diseases and their children are largely unmet, including the need for support to prepare for future medical decision making. This trial will test the FACE-Rare intervention to see if investigators can identify and meet those needs; and if FACE-Rare effects family caregivers' quality of life and child healthcare utilization. Finally, investigators will determine if the intersectionality of child-sex, family-race, Federal poverty level, and social connection influences family quality of life and child health care utilization longitudinally.
NCT07010471
A Phase 3, Randomized, Multi-Center, Double-Blind, Placebo-Controlled Clinical Trial to Evaluate the Efficacy, Safety, Tolerability, and Pharmacokinetics of Relutrigine in Participants with Developmental and Epileptic Encephalopathies Followed by an Open-Label Extension
NCT03936777
This is an international, multicenter, open-label, long-term safety study of ZX008 in subjects with Dravet syndrome, Lennox-Gastaut syndrome or epileptic encephalopathy
NCT07176832
This is a Phase I, open-label, randomized, single-center, two-way cross-over study evaluating the relative bioavailability, pharmacokinetics, safety, and palatability of two formulations of stiripentol (Diacomit®), indicated in Dravet syndrome. The investigational products are 500 mg capsules (reference) and a 50 mg/mL oral suspension (test). The primary objective is to compare the relative bioavailability of the two formulations after a single 1,000 mg oral dose under fed conditions, based on Cmax, AUC0-t, and AUC0-∞. Secondary objectives include other PK parameters (tmax, tlag, ke, t1/2) and characterization of metabolites MIa and MIb. Palatability of the suspension will be assessed by questionnaire. Safety evaluation will include adverse events, laboratory tests, ECGs, urinalysis, drug and alcohol screening, serology, and vital signs. Twenty-four healthy volunteers (18-50 years) will be enrolled. Eligibility: BMI 18-30 kg/m², weight ≥50 kg, normal ECG and labs, and informed consent. Women of childbearing potential must use effective contraception and test negative for pregnancy. Exclusions: significant disease, recent surgery or blood donation, hypersensitivity, difficulty swallowing, use of CYP modulators (e.g., carbamazepine, grapefruit, herbal products), drug or alcohol abuse, smoking \>5 cigarettes/day, or inability to follow dietary restrictions. Subjects testing positive for HIV, HBV, HCV, or drugs of abuse will also be excluded. Each participant will attend a screening visit within 28 days before dosing, then two 3-day hospitalizations separated by a 7-15-day washout. On Day 1 of each period, they will receive either two capsules (1,000 mg) or 20 mL suspension (1,000 mg). Blood will be collected at 36 timepoints (≈180 mL total) for PK assessment. The total study duration per subject is about seven weeks, including screening, hospitalization, dosing, washout, and follow-up. Treatment consists of one dosing day per period. Sample size was based on prior data: 21 pairs provide 80% power for bioequivalence within 0.80-1.25 bounds; 24 subjects will be recruited to account for dropouts. Analyses will include the Safety Set, PK Concentrations Set, and PK Analysis Set. This trial aims to establish whether the oral suspension provides a PK profile comparable to capsules, while generating safety, tolerability, and palatability data to support a more convenient formulation for Dravet syndrome patients.
NCT04625101
This is a phase 2, double-blind study to assess the efficacy, safety, tolerability, and pharmacokinetics of NBI-827104 when administered once daily for 13 weeks in pediatric subjects with Epileptic Encephalopathy with Continuous Spike-and-Wave During Sleep (EECSWS).
NCT05226780
Extension study to evaluate how safe and tolerable the drug NBI-921352 is when used as adjunctive therapy in participants with SCN8A developmental and epileptic encephalopathy syndrome (SCN8A-DEE).
NCT05364021
The objective of this study is to assess the safety, tolerability, efficacy, and pharmacokinetics of adjunctive therapy of LP352 in adults and adolescents with developmental and epileptic encephalopathies.
NCT03955432
The purpose of this research study to investigate, classify, and quantify chronic cardiac rhythm disorders in three groups of patients with epilepsy (intractable focal epilepsy, controlled focal epilepsy and symptomatic generalized epilepsy). Patients with epilepsy have a higher risk for cardiac complications than the general population. With this study, we aim to understand more about these potential complications in patients with epilepsy and assess if treatments for cardiac problems should be evaluated more carefully in patients with epilepsy.
NCT03779672
This study will evaluate the potential benefit of memantine hydrochloride as treatment for children with epileptic encephalopathy using a double-blind placebo-controlled cross-over design.
