Application Title:

Development of a universal allogeneic human interneuron cell therapy candidate for the treatment of drug resistant focal epilepsy.

Public Abstract:
Translational Candidate

Development of a universal allogeneic human interneuron cell therapy candidate for the treatment of drug resistant focal epilepsy.

Area of Impact

Non-destructive treatment option for drug-resistant focal epilepsy patients with reduced immunosuppression regimen and universal recipient eligibility

Mechanism of Action

The proposed therapeutic candidate comprises inhibitory interneurons that would be delivered in a one-time procedure into affected region of the brain and is intended to increase local GABAergic inhibitory tone and rebalance neural activity. The proposed candidate represents a cell replacement therapy that could compensate for the loss and dysfunction of the same types of neurons in the epileptic brain and possibly eliminate/significantly reduce seizures.

Unmet Medical Need

Epilepsy ranks as the fourth most common neurological condition in the US. One-third of people with epilepsy are classified as having seizures that are drug-resistant, which can be profoundly disabling and detrimental to their quality of life. Current treatment options do not typically culminate in seizure freedom and/or risk serious adverse events. Hence, there exists a compelling need to develop alternative therapies that are less invasive, non-destructive, safe, effective, and durable.

Project Objective

Pre-IND meeting with the FDA

Major Proposed Activities

  • Evaluation of candidate immunogenicity in a variety of human cellular and humanized mouse models.
  • Development and qualification of analytical assays and manufacturing of pilot universal allogeneic human interneuron cell therapy material.
  • Pilot Pharmacology, Dose-Finding, and Safety Studies in an established mouse model of TLE.
Statement of Benefit to California:
Epilepsy affects over 400,000 people in California, one-third of whom have seizures that are drug-resistant, can be disabling, and affect quality of life. A universal allogeneic inhibitory neuron cell therapy candidate will benefit California’s diverse population by providing a non-tissue destructive, regenerative treatment alternative for drug resistant focal epilepsy that does not require concurrent immunosuppression and improves safety, accessibility, and clinical utility for all patients.
