Disease Focus: Epilepsy

FIH Study of NRTX-1001 Neural Cell Therapy in Drug-Resistant Unilateral Mesial Temporal Lobe Epilepsy

The current therapies for drug-resistant epilepsy are only partially effective and have serious drawbacks.   One treatment that can significantly reduce seizure frequency is the removal of the affected part of the brain using surgical or laser ablation methods.  However, not surprisingly, removal of brain tissue can cause serious, irreversible damage, such as effects on memory, […]

Global gene expression profiling of single inhibitory neurons derived from human stem cells

Novel antisense therapy to treat genetic forms of neurodevelopmental disease.

Research Objective We propose to discovery and evaluate antisense gene therapy for specific mutations underlying debilitating or life-threatening neurodevelopmental diseases including epilepsy and autism syndromes. Impact The conditions are four specific neurodevelopmental syndromes where mutations are well suited to ASO therapy. The bottlenecks are current lack of cellular evidence for ASOs to impact disease course. […]

AAV-dCas9 Epigenetic Editing for CDKL5 Deficiency Disorder

Research Objective We propose a gene therapy for the treatment of a severe infantile epilepsy called CDKL5 Deficiency Disorder using CRISPR-mediated epigenetic editing Impact A transformative treatment for females affected by CDKL5 Deficiency Disorder in addition a platform for the approximately 38 other X-linked intellectual disabilities that predominately affect females Major Proposed Activities Validation of […]

Development of a Cellular Therapeutic for Treatment of Epilepsy

Research Objective A stem cell-derived nerve cell therapy to minimize seizures in people with epilepsy Impact Many people with epilepsy have uncontrolled seizures that can be life threatening and adversely impact quality of life and independence. A cell therapy could help those not responsive to drugs. Major Proposed Activities Transplant a nerve cell therapy made […]

Development of a human stem cell-derived inhibitory neuron therapeutic for the treatment of chronic focal epilepsy

Translational Candidate A cellular therapeutic comprised of inhibitory nerve cells produced from human stem cells Area of Impact Drug-resistant chronic temporal lobe epilepsy Mechanism of Action The product candidate is intended to be delivered into the seizure focus, integrate, and secrete the inhibitory neurotransmitter GABA to rebalance neural electrical activity in the brain and eliminate/reduce […]

Phase 1/2 Study of NRTX-1001 Neural Cell Therapy in Subjects with Drug-Resistant Unilateral Mesial Temporal Lobe Epilepsy

Therapeutic Candidate or Device NRTX-1001 is an inhibitory neuron cell therapy derived from human embryonic stem cells. Indication Focal epilepsy; drug-resistant mesial temporal lobe epilepsy. Therapeutic Mechanism NRTX-1001 is an inhibitory neuron cell therapy derived from human embryonic stem cells (hESCs) for the prospective treatment of drug-resistant focal epilepsy (MTLE). NRTX-1001 is delivered as a […]

Inhibitory Nerve Cell Precursors: Dosing, Safety and Efficacy

Many neurological disorders are characterized by an imbalance between excitation and inhibition. Our ultimate goal: to develop a cell-based therapy to modulate aberrant brain activity in the treatment of these disorders. Our initial focus is on epilepsy. In 20-30% of these patients, seizures are unresponsive to drugs, requiring invasive surgical resection of brain regions with […]

Derivation of Inhibitory Nerve Cells from Human Embryonic Stem Cells

Parkinson’s disease (PD) is caused by degeneration of a specific population of dopamine-producing nerve cells in the brain and is chronic, progressive, and incurable. Loss of dopamine-containing cells results in profound physiological disturbances producing tremors, rigidity, and severe deterioration of gate and balance. In the United States, approximately 1.5 million people suffer with PD and […]

MGE Enhancers to Select for Interneuron Precursors Produced from Human ES Cells

There are now viable experimental approaches to elucidate the genetic and molecular mechanisms that underlie severe brain disorders through the generation of stem cells, called iPS cells, from the skin of patients. Scientists are now challenged to develop methods to program iPS cells to become the specific types of brain cells that are most relevant […]
