​ Controlled Equity Offering Sales Agreement ​ In March 2017, the Company entered into a Controlled Equity Offering Sales Agreement (the “ATM Sales Agreement”), with Cantor Fitzgerald & Co., as sales agent (“Cantor Fitzgerald”), pursuant to which the Company may issue and sell, from time to time, through Cantor Fitzgerald, shares of the Company’s common stock, up to an aggregate offering price of $60,000 (the “ATM Shares”). Under the ATM Sales Agreement, Cantor Fitzgerald may sell the ATM Shares by methods deemed to be an “at-the-market” offering as defined in Rule 415 promulgated under the Securities Act of 1933, as amended (the “Securities Act”), including sales made directly on The NASDAQ Global Select Market, on any other existing trading market for the ATM Shares or to or through a market maker. In addition, under the ATM Sales Agreement, Cantor Fitzgerald may sell the ATM Shares by any other method permitted by law, including in privately negotiated transactions. The Company is not obligated to make any sales of the ATM Shares under the ATM Sales Agreement. The Company or Cantor Fitzgerald may suspend or terminate the offering of ATM Shares upon notice to the other party and subject to other conditions. The Company will pay Cantor Fitzgerald a commission of up to 3.0% of the gross proceeds from the sale of the ATM Shares pursuant to the ATM Sales Agreement and has agreed to provide Cantor Fitzgerald with customary indemnification and contribution rights. ​ No shares were sold pursuant to the ATM Sales during the six months ended June 30, 2019 or the year ended December 31, 2018. ​ Warrants ​ As of June 30, 2019, the warrant issued to Assertio in November 2018 was the Company’s only outstanding warrant, which is described in greater detail in Note 8.
