Nerve Damage Research Trial - SAD

A Phase I, prospective, double-blind, randomised, placebo-controlled, dose escalation study to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of single and multiple ascending oral doses of KCL-286 and the effects of food in healthy male participants

Damage to nerves in the arm, for example from the trauma possibly caused in a road traffic accident, can result in the nerve roots being torn from the spinal cord, known as a brachial plexus injury. In these situations the main effects often seen are problems with movement (motor control), loss of sensations (sensory control) and pain. Once the nerves have been torn from the spinal cord a scar is formed at the site of the injury and this becomes a barrier to recovery as it prevents the nerves growing back in the spinal cord. Current treatments in place for brachial plexus injuries often do not result in full return of functions or sufficient pain relief. Some treatments used involve surgery to implant nerves; this technique has been shown to result in some return of motor function and easing of pain but not return of sensations and it is thought that this may in part be due to the formation of the scar.

 

Results of studies in animals have shown that early administration of KCL-286 (the medication being investigated in this study) prevents a scar from forming where the nerves have been torn from the spinal cord and therefore this allows the nerves to grow back preventing the loss of functions, including the loss of sensations.

 

This study is the first study to give KCL-286 to humans. It will be given to healthy males (who do not have brachial plexus injuries) to investigate whether it has any side effects in humans and also to determine the appropriate doses to investigate in patients with brachial plexus injuries.
