Subsequent Events [Abstract] |
Subsequent Events | Subsequent Events Common Stock Sales Agreement On February 8, 2018, we entered into a Common Stock Sales Agreement with H.C. Wainwright & Co., LLC ("HCW"), as sales agent, in connection with an “at the market offering” under which we from time to time may offer and sell shares of our common stock, having an aggregate offering price of up to $12 million. Subject to the terms and conditions of the sales agreement, HCW will use its commercially reasonable efforts consistent with its normal trading and sales practices to sell the shares from time to time, based upon our instructions, including any price, time or size limits specified by us. We have provided HCW with customary indemnification rights, and HCW will be entitled to a commission at a fixed commission rate equal to 3.0% of the gross proceeds per share sold. We have no obligation to sell any of the shares, and may at any time suspend sales under the sales agreement or terminate the sales agreement. The sales agreement will terminate upon the sale of all of the shares under the sales agreement unless terminated earlier by either party as permitted under the sales agreement.
