After successfully improving muscle tone in spinal cord injury patients in clinical trials, a new drug is progressing into the next phase of tests.
Arbaclofen placarbil (AP), also known as XP19986, will be tested on multiple sclerosis (MS) patients in Phase 3 clinical trials, the drug's maker biopharmaceutical firm Xenoport has said.
A successful trial with MS sufferers could see the firm filing for a new drug application from the US Food and Drug Administration for the treatment of spasticity.
XenoPort chief executive officer Ronald W Barrett said: "In our previous Phase 2 clinical trial in spinal cord injury patients with spasticity, AP was well tolerated and demonstrated dose-dependent improvement in muscle tone that was maintained throughout the 12-hour dosing interval."
He went on to say that similar results are hoped for in the next phase of clinical trials.
Spasticity is a side effect of paralysis that usually results from damage to the portion of the brain or spinal cord that controls voluntary movement.
