UPDATE 1-Zogenix epilepsy drug meets main goal in late-stage trial

(Adds details, share suspension)

Sept 29 (Reuters) - Zogenix Inc's experimental treatment for a rare form of epilepsy met the main goal in a late-stage study, the company said on Friday, keeping it on track to request regulatory approval next year.

The drug - ZX008 - was shown to be superior compared to a placebo in reducing the frequency of seizures in children with Dravet syndrome, a genetic dysfunction in the brain which results in potentially fatal, long-lasting, fever related seizures that do not respond to standard treatment.

It also said the drug reduced the number of patients suffering seizures in comparison with a placebo.

The company said it expected to report data from a second late-stage trial in the first half of next year and remained on track to submit regulatory approvals for the drug in the United States and Europe in the second half of 2018.
