Epilepsy device maker NeuroSigma withdraws $50 million IPO

NeuroSigma, which sells bio-electrical devices used to treat drug-resistant epilepsy and depression, withdrew its plans for an initial public offering on Monday. It postponed its $50 million IPO in October 2014.

The Los Angeles, CA-based company was founded in 2008. It had planned to list on the Nasdaq under the symbol NSIG. NeuroSigma initially filed confidentially on 11/27/2013. Jefferies was set to be the sole bookrunner on the deal.
