Glaucoma drug developer Aerie Pharmaceuticals (NASDAQ:AERI) is now a public company, raising $67 million in an initial public stock offering that the company plans to use for clinical trials of its leading drug candidates.

But at $10 per share, the IPO was below the stock range of $12 to$14 per share that the company had set last week. The New Jersey company, which operates its R&D labs in Research Triangle Park, also had to sell more shares to reach that $67 million mark. On Thursday, the company filed to add 1.69 million shares to the 5.25 million shares it planned to sell in the stock offering.

Aerie opened at $10.40 per share and throughout the day traded in a range of $10.25 and $10.86 cents per share. The stock closed at $10.61, up 6 percent from the offering price.

RBC Capital Markets and Stiefel are joint-book running managers for the offering. Canaccord Genuity Inc. and Needham & Company are co-managers. The offering is expected to close on Oct. 30. Underwriters have a 30-day option to purchase 1 million additional shares of common stock to cover any over-allotments.

Aerie, whose technology is based on research originally developed at Duke University, has two clinical-stage compounds focused on glaucoma. The company’s lead candidate, a “dual-action” product, has completed phase II clinical trials and is ready to start phase III studies. A second candidate approaches glaucoma with a “triple action” mechanism. That compound is advancing to phase II studies.
