What happened

After reporting third-quarter financials yesterday and updating investors on its clinical-stage drug pipeline, Omeros Corporation (NASDAQ:OMER) is rocketing 17.7% higher today at 1 p.m. EST.

So what

Omeros Corporation's only commercial drug is Omidria, a therapy used in cataract and intraocular lens replacement procedures, and its sales are growing rapidly. Omidria revenue increased 248% year over year to $11.3 million in the third quarter. Quarter over quarter, sales improved 13% on an 18% increase in units sold.

Omidria's rising revenue is encouraging, but a flurry of clinical-stage trials on other medicines still caused Omeros to lose $14 million, or $0.34 per share, in the quarter. For comparison, the company reported a loss of $19.9 million, or $0.53 per share, last year.

Management also brought investors up to date on its progress on drugs under development, including OMS721. The company is evaluating OMS721 in kidney disorders with limited treatment options, such as atypical hemolytic uremic syndrome (aHUS). The company is advancing OMS721 into phase 3 studies in aHUS, and if successful, those trials could clear the way for a speedy FDA decision. Previously, the FDA granted OMS721 fast-track designation for aHUS, which could accelerate a decision from 10 months to six months. Positive mid-stage trial results of OMS721 in IgA nephropathy, and in thrombotic microangiopathy occurring after allogeneic hematopoietic stem cell transplantation (HSCT-TMA), are also encouraging to investors. Said Dr. Gregory A. Demopulos, chairman and CEO of Omeros, in a press release:

Omeros' achievements this quarter underscore the breadth and strength of our commercial and development programs ... OMIDRIA revenues have grown by double digits every quarter since launch, and we expect that growth to continue. We have expanded the indications for our late-stage complement inhibitor OMS721 beyond our Phase 3 program in aHUS and have recently reported positive data across four Phase 2 clinical trials in the hematologic, renal and addiction fields. With OMIDRIA revenues growing and the recent restructuring of our debt, we expect that we have the necessary funds to advance significantly the development of our robust pipeline.

Now what

The company spent $23.3 million on operating expenses last quarter, and that's potentially a problem because management says: "With funds on hand and current annualized Omidria revenues and expenses, we anticipate that the company has at least 12 months of operating capital." Depending on the timeline for OMS721, the company's cash burn could cause it to tap investors for more capital via a dilutive stock offering next year.

Overall, Omidria is gaining traction and OMS721 is advancing, but the company has some financial question marks. Therefore, this stock might only be suited to highly risk-tolerant investors.
