CRC 385 SAD Cohorts 6 - 8

Study drug KCL-286 has been designed to treat nerve damage, for example from the trauma possibly caused in a motor cycle accident. These accidents can result in the nerve roots being torn from the spinal cord, known as a brachial plexus injury, when the nerves in the “arm pit” are damaged. In these situations the main effects often seen are problems with movement, loss of sensations and pain. Once the nerves have been torn from the spinal cord a scar is formed on the nerve endings.

This 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.

To date there have been no related safety concerns from the participants who have received a dose of study drug.
