LEXINGTON, Mass., June 16, 2015 /PRNewswire/ -- Pulmatrix, Inc., (NASDAQ: PULM), previously known as Ruthigen, Inc., today announced the completion of its previously announced merger, effective June 15, 2015, and the closing of a private placement generating aggregate gross proceeds of $10.0 million. Participants in the private placement included pre-merger investors in Pulmatrix such as funds affiliated with 5AM Ventures, ARCH Venture Partners and Polaris Partners, as well as funds affiliated with Altitude Life Science Ventures. Trading in Pulmatrix's common stock will commence today on NASDAQ on a post-reverse-stock-split basis (CUSIP No. 74584P103).

"This new funding enables further development our proprietary pipeline of inhaled therapeutics for rare diseases, led by our anti-fungal candidate for cystic fibrosis and our branded generic for chronic obstructive pulmonary disease," said Robert W. Clarke, Ph.D., Chief Executive Officer of Pulmatrix. "Following the financing and merger, we have $27 million in cash, which we expect will fund our business into 2017, beyond multiple data readouts from ongoing and planned clinical studies, as well as other corporate milestones."

For the remainder of 2015 and throughout 2016, Pulmatrix plans to focus on achieving the following milestones:

• 2H 2015: Initiate European pharmacokinetic bioequivalence clinical study to advance development of PUR0200, Pulmatrix's bronchodilator therapy candidate;
• 1H 2016: Report pharmacokinetic profile of PUR0200 versus the reference product from the bioequivalence clinical study;
• 2H 2016: Initiate a Phase 1 trial and generate initial data for PUR1900, which would become the first inhaled product candidate in development for treatment of fungal infections in cystic fibrosis patients;
• 1H 2016: Identify active pharmaceutical ingredient for PUR1500, Pulmatrix's drug candidate for idiopathic pulmonary fibrosis;
• Further strengthen patent protection for Pulmatrix's iSPERSE (Inhaled Small Particles Easily Respirable and Emitted) platform and related therapeutic applications; and
• Expand Pulmatrix's senior management team.

Immediately prior to the effective time of the merger, private company Pulmatrix closed a $10.0 million private placement pursuant to which 1,454,454 shares of post-merger common stock were issued. In addition, in connection with this private placement and in recognition of the fact that a majority of these investors (i) surrendered warrants in private company Pulmatrix and (ii) and converted approximately $30 million principal amount of non-convertible debt into equity for no consideration, investors in this private placement also received warrants to purchase 3,190,000 shares of post-merger common stock at an exercise price of $7.56 per share, which only become exercisable upon Pulmatrix's achievement of certain performance milestones. 

Immediately prior to the effective time of the merger, Ruthigen closed a private placement, led by Dr. Phillip Frost Chairman & CEO of OPKO Health, Inc.

The merger was structured as a stock-for-stock transaction, whereby all outstanding shares of Pulmatrix's common stock were converted into the right to receive 0.148 shares of common stock in the predecessor company Ruthigen, Inc. The share numbers and prices in the preceding two paragraphs give effect to a 1-for-2.5 reverse stock split of the post-merger common stock that occurred immediately following the merger.

Immediately after the issuance of shares to private company Pulmatrix's stockholders in connection with the merger and transactions described above, private company Pulmatrix stockholders owned approximately 81.7% of the combined company's outstanding common stock and pre-merger Ruthigen stockholders owned approximately 18.3% of the combined company's outstanding shares of common stock, excluding the shares of common stock held in escrow to secure indemnification obligations.
