Financial Highlights


    --  First quarter 2013 DIFICID net product sales in the U.S. and Canada of
        $16.8 million, compared to $14.4 million in 2012
    --  First quarter 2013 total net revenues of $19.4 million
    --  Cash, cash equivalents and short-term investments at March 31, 2013
        totaled $93.3 million
    --  2013 net loss for the first quarter was $31.3 million, or $0.65 per
        share

"Net product sales in the first quarter of $16.8 million were essentially flat from the fourth quarter. We believe net product sales, which are derived from shipments to wholesalers and specialty pharmacies, were negatively impacted by an inventory sell-down by wholesalers. We saw a nearly 5% increase in demand for DIFICID during the quarter, as determined by estimated shipments from wholesalers to hospitals and retail and long-term care pharmacies, and we see continuing increased demand through April," said Dr. Henry McKinnell, Optimer's CEO and Chairman of the Board. "As we move toward mid-year and beyond, I am confident that if we maintain our focus on establishing DIFICID as an important treatment option for patients with CDAD, including execution on the strategic initiatives started in the latter part of 2012, we will improve adoption of DIFICID."

Financial Overview

Total net revenues for the quarters ended March 31, 2013 and 2012 were $19.4 million and $14.4 million, respectively, an increase of $5.0 million. The increase was due to an increase in DIFICID net product sales and an increase in contract revenue.

DIFICID net product sales in the United States and Canada for the quarters ended March 31, 2013 and 2012 were $16.8 million and $14.4 million, respectively, an increase of $2.4 million. This increase was due to an increase in the number of customers ordering DIFICID and increased sales to existing DIFICID customers, as well as the impact of a 5.6% price increase effective January 3, 2013. We recognize product sales of DIFICID upon delivery of product to our wholesalers.

Contract revenue for the quarter ended March 31, 2013 was $2.6 million. There was no contract revenue in the quarter ended March 31, 2012. The $2.6 million was related to fidaxomicin shipments to Astellas Pharma Europe, Astellas Japan, AstraZeneca and Specialised Therapeutics Australia, as well as royalties received from Astellas Pharma Europe. In addition, we recognized approximately $0.3 million of revenue on the up-front payments we received from AstraZeneca and Astellas Japan in the prior year.

Cost of product sales for the three months ended March 31, 2013 and 2012 was $1.6 million and $1.2 million, respectively. The increase was due to higher net product sales in the quarter ended March 31, 2013 as compared to the year-ago period.

Research and development expense for the quarters ended March 31, 2013 and 2012 was $9.9 million and $11.1 million, respectively, a decrease of $1.2 million. The decrease was primarily due to lower chemistry, manufacturing and control (or CMC) expenses, as well as lower consulting expenses. The decrease was offset by higher health economics and outcomes research expenses. We also incurred higher expenses related to our prophylaxis and pediatric clinical trials.

Selling, general and administrative expense for quarters ended March 31, 2013 and 2012 was $34.0 million and $25.5 million, respectively, an increase of $8.5 million. The increase primarily was due to higher legal, professional and outside service expenses. We also recognized higher stock compensation expense, primarily related to previously announced management departures.

Co-promotion expenses with Cubist for the quarters ended March 31, 2013 and 2012 were $3.8 million and $10.1 million, respectively, a decrease of $6.3 million. The co-promotion expenses for the quarter ended March 31, 2012 included an accrual of the first-year sales target bonus and an accrual of the first-year gross profit on sales above the sales target.

Net loss for the first quarter of 2013 was $31.3 million, or $0.65 cents per share, on a basic and diluted basis, as compared to net loss for the first quarter of 2012 of $10.9 million, or $0.23 cents per share, on a basic and diluted basis. The net loss in the year-ago quarter was favorably impacted by a $23.8 million gain on the deconsolidation of OBI.

At March 31, 2013, Optimer held cash, cash equivalents and short-term investments of $93.3 million.

Optimer had 48.0 million shares outstanding on March 31, 2013.

"As we maintain our focus and commitment to establishing DIFICID as an important first-line treatment option for patients, we are similarly focused on conducting our review of strategic alternatives so that we can optimize value for our stockholders," continued Dr. McKinnell.

About DIFICID® (fidaxomicin) Tablets
DIFICID is the first macrolide antibacterial drug indicated for Clostridium difficile-associated diarrhea (CDAD) to be approved in over 25 years in the U.S. It is indicated in the U.S. for the treatment of CDAD in adults 18 years of age or older. DIFICID is administered in 200 milligram tablets given orally, twice daily.

Important Safety Information for DIFICID
DIFICID is contraindicated in patients with hypersensitivity to fidaxomicin. DIFICID should not be used for systemic infections. Acute hypersensitivity reactions (angioedema, dyspnea, pruritus, and rash) have been reported. In the event of a severe reaction, discontinue DIFICID. Only use DIFICID for infection proven, or strongly suspected, to be caused by C. difficile. Prescribing DIFICID in the absence of a proven or strongly suspected C. difficile infection is unlikely to provide benefit to the patient and increases the risk of the development of drug resistant bacteria. The most common adverse reactions reported in clinical trials are nausea (11%), vomiting (7%), abdominal pain (6%), gastrointestinal hemorrhage (4%), anemia (2%) and neutropenia (2%).
