  • Proteon Therapeutics Announces $22.0 Million Private Placement

    June 23, 2017

Provides Sufficient Cash into Q4 2019

WALTHAM, Mass., June 22, 2017 (GLOBE NEWSWIRE) — Proteon Therapeutics Inc. (Nasdaq:PRTO), a company developing novel, first-in-class therapeutics to address the medical needs of patients with kidney and vascular diseases, today announced that it has entered into a securities purchase agreement with a syndicate of current and new investors, led by an affiliate of Deerfield Management (“Deerfield”), for the sale of 22,000 shares of the Company’s Series A Convertible Preferred Stock (“Preferred Stock”) for gross proceeds of $22.0 million. Other participants in the financing include Abingworth, Fairmount Funds, Perceptive Advisors, Pharmstandard, RA Capital, Skyline Ventures, TVM Capital Life Science and certain other stockholders who invested prior to Proteon’s initial public offering.

The Company intends to use the proceeds from the transaction to complete the ongoing PATENCY-2 trial and fund continued market access activities. The financing also extends the Company’s cash runway from the third quarter of 2018 into the fourth quarter of 2019, which allows the Company to operate for more than six months beyond the expected release of topline data from the PATENCY-2 Phase 3 clinical trial based on the Company’s current operating plan.

The consummation of the transaction is subject to the satisfaction of closing conditions, including approval of the Company’s stockholders.  Stockholders of the Company representing in excess of 60% of Proteon’s shares outstanding have entered into agreements to vote in favor of approving this transaction at the special meeting of stockholders required to approve the transaction. The transaction is expected to close in the third quarter of 2017.

The holders of Preferred Stock will be entitled to elect one director to the Company’s Board of Directors.  It is expected that Jonathan Leff, a Partner at Deerfield Management, will be named to the Company’s Board of Directors upon closing of the transaction as the designee of the Preferred Stock holders.

“We are pleased to announce this financing, led by Deerfield, as it reflects the continued confidence in the clinical and economic potential of vonapanitase and in our execution of the ongoing Phase 3 trial,” said Timothy Noyes, President and Chief Executive Officer of Proteon. “We are also pleased to welcome Jonathan Leff to our Board of Directors upon closing of this transaction. Jonathan will bring tremendous experience and leadership and will be a valuable addition to our Board.”

“Deerfield originally invested in Proteon in 2014 because of the substantial unmet medical need and our confidence in the management team and technology,” said Jonathan Leff, a Partner at Deerfield Management. “We were encouraged by the recently announced results from the Phase 3 PATENCY-1 trial and the subsequent interactions with the FDA, including the granting of Breakthrough Therapy Designation.”

The Preferred Stock will be convertible into 22,112,775 shares of common stock at closing, which equates to a conversion price of $0.9949 per share, provided that any conversion of the Preferred Stock will be prohibited if, as a result of such conversion, the holder and its affiliates would own more than 9.985% of the total number of the Company’s shares of common stock issued and outstanding after such conversion. In the event of certain transactions involving mergers, consolidations, tender offers and the sale of all or substantially all the assets of the Company, each share of Preferred Stock would be convertible into the kind and amount of securities, cash and/or other property that the holder of a number of shares of common stock issuable upon conversion of one share of Preferred Stock would receive pursuant to any such transaction; provided that, in the event any such transaction occurs prior to a preference termination date relating to FDA approval of the Company’s product and the trading price of the Company’s common stock, if the aggregate value of such securities, cash and/or property to which a holder of a share of Preferred Stock would be entitled upon conversion would be less than the price per share paid for the Preferred Stock (the “Stated Value”), then each share of Preferred Stock shall instead be convertible into such kind of securities, cash and/or other property with an aggregate value equal to the Stated Value. Except as otherwise required by law (or with respect to the election of one director to the Company’s Board of Directors and approval of certain actions specified in terms of the Preferred Stock), the Preferred Stock will not have voting rights. No dividends are expected to be paid on the Preferred Stock. In addition, the Company has agreed to grant the investors certain registration rights with respect to the common stock underlying the Preferred Stock.

No placement agent fee will be paid in connection with this transaction.

Please refer to the Company’s Form 8-K to be filed with the Securities and Exchange Commission (“SEC”) for the complete terms of the convertible preferred stock transaction.

This press release shall not constitute an offer to sell or the solicitation of an offer to buy any of these securities, nor shall there be any sale of any these securities in any state or other jurisdiction in which such offer, solicitation or sale would be unlawful. The securities to be sold pursuant to the securities purchase agreement will not have been registered under the Securities Act of 1933, as amended, or state securities laws as of the time of issuance and may not be offered or sold in the United States absent registration with the SEC or an applicable exemption from such registration requirements.
