Item 2. Identity and Background.

(a) This Schedule 13D is being filed on behalf of each of the following persons pursuant to Rule 13d-1(k) of Regulation D-G under the Securities Exchange Act of 1934, as amended (the "Exchange Act"):  (i) Domain Partners VIII, L.P., a Delaware limited partnership ("DP VIII"), and (ii) DP VIII Associates, L.P., a Delaware limited partnership ("DP VIII A") (each, a "Reporting Person" and together, the “Reporting Persons”).  The Reporting Persons are making this single, joint filing because they may be deemed to constitute a "group" within the meaning of Section 13(d)(3) of the Exchange Act.  The agreement among the Reporting Persons to file as a group (the “Joint Filing Agreement”) is attached hereto as Exhibit A.

Halak, and Nicole Vitullo are the managing members of OPSA VIII.  The principal business address of each of the entities and individuals named in this Item 2 is c/o Domain Associates, LLC., One Palmer Square, Princeton, New Jersey  08542.

(d)–(e) During the last five years, none of the Reporting Persons or individuals named in this Item 2 has been  (i) convicted in any criminal proceeding (excluding traffic violations or similar misdemeanors); or (ii) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction resulting in his being subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

(f) Each of the individuals named in this Item 2 is a citizen of the United States.

Item 3. Source and Amount of Funds or Other Consideration.

 
On March 30, 2017, the Issuer entered into a Redeemable Convertible Preferred Stock Purchase Agreement (the “Purchase Agreement”) with the investors identified on the signature pages thereto, including the Reporting Persons (the “Investors”), pursuant to which the Investors purchased from the Issuer on April 11, 2017 (the “Private Placement”) an aggregate of 700,000 shares of the Issuer’s Redeemable Convertible Preferred Stock, par value $0.0001 per share (the “Redeemable Convertible Preferred Stock”), at a purchase price of $100 per share .  DP VIII purchased 49,632 shares of such Redeemable Convertible Preferred Stock and DP VIII A purchased 368 shares of such Redeemable Convertible Preferred Stock, for an aggregate purchase price of $5,000,000.  The source of funds for such purchase was the working capital of DP VIII and DP VIII A. The Purchase Agreement is incorporated herein as Exhibit B by reference to Exhibit 10.1 to the Report on Form 8-K filed by the Issuer with the Securities and Exchange Commission on March 30, 2017, and any description thereof is qualified in its entirety by reference thereto.

CUSIP No. 253031108

 
Each share of Redeemable Convertible Preferred Stock is convertible into a number of shares of Common Stock equal to the accrued value of the Redeemable Convertible Preferred Stock divided by the conversion price, with cash payment in lieu of fractional shares. The accrued value per share of Redeemable Convertible Preferred Stock is initially $100 per share, and will be increased by a paid-in-kind dividend at a rate of 12% per annum (which rate may be reduced upon the occurrence of specified corporate events), compounded quarterly, subject to customary anti-dilution adjustments. The conversion price is initially $3.19, subject to customary anti-dilution adjustments.
 
The Redeemable Convertible Preferred Stock is convertible at any time at the option of the holder.  In addition, the Issuer has the right to require each holder of Redeemable Convertible Preferred Stock to convert such Redeemable Convertible Preferred Stock into Common Stock (a “Mandatory Conversion”) at any time following the earlier of (i) the second anniversary of the closing of the Private Placement or (ii) the occurrence of certain corporate events, provided that, in either case, the closing sale price of the Common Stock exceeds 200% of the conversion price for 45 out of the 60 most recent trading days.  Whether voluntary or by means of a Mandatory Conversion, the conversion of shares of Redeemable Convertible Preferred Stock into Common Stock is subject to a 19.99% blocker (the “19.99% Blocker”), pursuant to which no conversion of the Redeemable Convertible Preferred Stock may be effected to the extent that following such conversion, the holder and its affiliates would beneficially own in excess of 19.99% of the voting power of the Issuer. The 19.99% Blocker will be effective until (a) the Issuer obtains the approval of its stockholders as required by the applicable rules of the NASDAQ Global Select Market or (b) the Issuer is not subject to such rules. Holders of Redeemable Convertible Preferred Stock are entitled to vote a number of votes equal to the number of shares of the Common Stock into which such holder’s Redeemable Convertible Preferred Stock is convertible, taking into account the 19.99% Blocker.
 
The Certificate of Designation of the Redeemable Convertible Preferred Stock is incorporated herein as Exhibit C by reference to Exhibit 3.1 to the Report on Form 8-K filed by the Issuer with the Securities and Exchange Commission on March 30, 2017, and any description thereof is qualified in its entirety by reference thereto.
 
The Reporting Persons acquired an aggregate 1,765,711 shares of Common Stock and 21,197 Warrants to purchase Common Stock upon the automatic conversion of shares of Series B Preferred Stock, Series C Preferred Stock and Warrants to purchase Series C Preferred Stock of the Issuer in connection with the closing of the Issuer’s initial public offering on February 4, 2014.  The Reporting Persons had acquired such Series B Preferred Stock, Series C Preferred Stock and Warrants to purchase Series C Preferred Stock from the Issuer in private offerings.  The source of funds for such purchases was the working capital of DP VIII and DP VIII A. The Warrants to purchase Common Stock are presently-exercisable at an exercise price of $7.00 per share, and expire on June 26, 2018.

Item 4. Purpose of Transaction.
 
DP VIII and DP VIII A participated in the Private Placement for investment purposes.  Brian K. Halak is a Director of the Issuer and is a managing member of  OPSA VIII, but except as otherwise described in this statement, the Reporting Persons do not have any present plans or proposals that relate to or would result in: (i) the acquisition by any person of additional securities of the Issuer, or the disposition of securities of the Issuer; (ii) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries; (iii) a sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (iv) any change in the present board of directors or management of the Issuer, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board; (v) any material change in the present capitalization or dividend policy of the Issuer; (vi) any other material change in the Issuer’s business or corporate structure; (vii) changes in the Issuer’s charter, by-laws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person; (viii) causing a class of securities of the Issuer to be de-listed from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (ix) a class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Exchange Act; or (x) any action similar to any of those enumerated above.  The Reporting Persons may change their present intentions at any time and therefore reserve their right to make alternative plans or proposals in the future or take any other steps to enhance the value of their investment.  The Reporting Persons further reserve the right to increase, decrease (including by distributions in kind to their partners or members) or eliminate their investment in the Issuer, or take any other action relative thereto, in all cases as permitted by the relevant securities laws and any agreement or agreements that have been or may be entered into with the Issuer.
