MDA Kickstart Program

MDA advocates for over 300 neuromuscular conditions, with 95% of these affecting less than 1000 individuals in the United States. For therapies to effectively reach the patient community, they traditionally require transitioning from the academic research space to a commercial drug development pipeline; but, because of the small market sizes of many of these diseases, they have only marginal, if any, commercial value. The MDA's Kickstart Program aims to overcome the lack of commercial incentive by bridging the translational gap between early academic science and commercial drug development and leveraging regulatory incentives like the Rare Pediatric Voucher program, to help to de-risk gene therapy programs enough to bring them over the threshold for profitability. MDA’s Kickstart Program brings together a collaborative team consisting of in-house and external experts with research, clinical and regulatory expertise to guide gene therapy programs through the drug development process. The program will be scaled across multiple diseases through sharing of resources including master service agreements and regulatory learnings. Kickstart will document lessons learned to provide a blueprint for other advocacy organizations who share an interest in pursuing drug development for very rare diseases.

Kickstart pilot case: congenital myasthenic syndrome due to ChAT deficiency

The pilot project for MDA’s Kickstart program focuses on the development of a gene therapy for a form of Congenital Myasthenic Syndrome (CMS) caused by mutations in the Choline acetyltransferase (ChAT) gene. Disease-causing mutations in the ChAT gene cause disruptions in signal transmission from nerve cells to muscles, and result in muscle weakness and potentially fatal apnea. CMS due to ChAT deficiency (CMS-ChAT) affects about 100-150 children and adults in the United States and is characterized by muscle weakness and life-threatening episodes in which breathing stops. This program is a collaboration with Dr. Ricardo Maselli (UC Davis) who is a world recognized clinician and researcher in congenital myasthenic syndromes. Recently, Dr. Maselli published results on restoration of ChAT-deficiency in mice using adeno-associated virus (AAV) gene therapy (pubmed.ncbi.nlm.nih.gov/38299967). The gene therapy technology established by Dr. Maselli forms the basis for our Kickstart drug development program. MDA is currently working with Dr. Maselli to conduct the necessary studies to meet an early FDA milestone (pre-IND) for drug development.

About CHAT-CMS

Congenital Myasthenic Syndromes (CMS) are a diverse group of neuromuscular disorders affecting the neuromuscular junction, the site where nerve signals are transmitted to muscles. Approximately 5% of CMS cases are associated with mutations in the choline O-acetyltransferase (CHAT) gene, which encodes an enzyme crucial for synthesizing acetylcholine, a neurotransmitter essential for muscle contraction (See Figure below). Mutations in CHAT lead to reduced acetylcholine production, impairing communication between nerves and muscles. This disruption can cause symptoms ranging from mild muscle fatigue and occasional sudden loss of muscle tone to severe muscle weakness, potentially leading to respiratory failure and bulbar deficits that require tracheostomy, continuous mechanical ventilation, and lifelong gastric tube feeding. The severity of CHAT-CMS varies greatly among individuals, with symptoms typically appearing in infancy or early childhood. A key feature of CMS is the rapid onset of muscle fatigue, which can occur within minutes, unlike the slower fluctuations seen in other neuromuscular disorders. This rapid fatigue can lead to life-threatening apneas. Management focuses on symptomatic relief, often using medications that enhance neuromuscular transmission, such as acetylcholinesterase inhibitors, along with supportive therapies and regular monitoring to improve quality of life and symptom control.

A technical diagram described below.
Figure: Synthesis of acetylcholine at the neuromuscular junction. (1) Acetylcholine (ACh) synthesis is catalyzed by choline acetyltransferase (CHAT) in the axoplasm of the nerve terminal from its precursors using acetyl coenzyme A and choline. (2) ACh is transported into storage synaptic vesicles which are then released into the synaptic cleft (3) Released ACh binds receptors (AChR) on the post-synaptic membrane. (4) Hydrolysis of ACh by the enzyme acetylcholinesterase. 4) Reuptake of choline into the nerve terminal through the choline transporter. Created with BioRender.com.

The research objectives of the ChAT program are the following:

  1. Design CHAT constructs with three different candidate promoters and perform validation of CHAT expression
  2. Conduct umbrella study in vivo to determine top candidate construct for advancement into the clinic
  3. Conduct dose-finding study with selected candidate construct to determine optimal dose for IND-enabling studies
  4. Evaluate a preliminary safety profile of the selected construct to guide design of IND-enabling tox studies
  5. Develop and validate an in vitro potency assay based on enzymatic activity of CHAT
  6. Conduct an informative pre-IND meeting with the FDA
  7. Evaluate availability of natural history data and conduct benefit/risk assessments with this population
