The publication describes a live-cell screening strategy targeting abnormal electrophysiological properties to reveal targets that modulate the intrinsic hyperexcitability of ALS motor neurons.

Key Points: 
  • The publication describes a live-cell screening strategy targeting abnormal electrophysiological properties to reveal targets that modulate the intrinsic hyperexcitability of ALS motor neurons.
  • This unbiased screen using human ALS motor neurons identified Kv7.2/7.3 as a strongly overrepresented drug target.
  • Previous research has identified Kv7.2/7.3 as an ALS drug target and the unbiased nature of this screen further emphasizes the importance of Kv7.2/7.3 in ALS motor neuron dysfunction.
  • We are advancing three antisense and small molecule programs addressing sub-forms of ALS that account for the majority of ALS patients.

QRA-244 is a Kv7.2/7.3 ion channel opener optimized for both safety and efficacy as a potential treatment for motor neuron hyperexcitability-induced neurodegeneration in ALS patients.

Key Points: 
  • QRA-244 is a Kv7.2/7.3 ion channel opener optimized for both safety and efficacy as a potential treatment for motor neuron hyperexcitability-induced neurodegeneration in ALS patients.
  • Importantly, QRA-244 showed dramatic reductions in side effects associated with retigabine including fatigue/somnolence, dizziness and bladder retention in head-to-head pre-clinical studies.
  • Degeneration of motor neurons in ALS patients leads to loss of innervation of muscles, which leads to paralysis and eventually fatality.
  • Together with a world-class network of thought leaders, drug developers and patient advocates, our team is rising to the challenge of conquering ALS.
