Press Release

DURHAM, N.C., May 13, 2013 (GLOBE NEWSWIRE) -- Chimerix, Inc. (Nasdaq:CMRX), a biopharmaceutical company developing novel, oral antivirals in areas of high unmet medical need, today reported financial results for the quarter ended March 31, 2013.

"Since the beginning of the year Chimerix has achieved significant progress in important corporate and clinical milestones," said Kenneth I. Moch, President and CEO of Chimerix. "Key among these is the successful completion of our Initial Public Offering (IPO), generating $117.9 million in gross proceeds. In the first quarter, the U.S. Food and Drug Administration (FDA) granted Fast Track designation for CMX001 for the prevention of cytomegalovirus (CMV) infection in adult hematopoietic stem cell transplant (HSCT) recipients, and we recently announced the final study design for the Phase 3 SUPPRESS trial of CMX001 in this indication. The primary use of our IPO proceeds will be to initiate SUPPRESS later this year and conduct the trial through completion and data release which is targeted for 2015."

Business Highlights

• Completed IPO generating gross proceeds of $117.9 million
• Finalized study design for Phase 3 SUPPRESS trial of CMX001 for the prevention of CMV infection in HSCT recipients
• Successfully completed Clinical Pharmacology studies including a Dedicated QTc Study required to initiate dosing in SUPPRESS

First Quarter 2013 Financial Results

Chimerix reported a net loss of $9.1 million which, when coupled with the $25.5 million in accretion of redeemable convertible preferred stock, resulted in a net loss of $22.58 per basic and diluted share for the first quarter of 2013. For the first quarter of 2012, Chimerix had a net loss of $6.9 million which, when coupled with the $0.9 million in accretion of redeemable convertible preferred stock, resulted in a net loss of $5.14 per basic and diluted share. The increase in net loss per basic and diluted share in the first quarter of 2013 compared to the prior year period is primarily due to the increase in accretion of redeemable convertible preferred stock.

Revenues for the first quarter of 2013 were $1.8 million, compared to $3.1 million for the same period in 2012. Revenues for both quarters consisted of contract revenue from Chimerix's contract with the Biomedical Advanced Research and Development Authority (BARDA) for the development of CMX001 as a medical countermeasure against smallpox. The decrease in revenue for the first quarter of 2013 compared to the prior year period is a reflection of Chimerix nearing completion of the base segment of the BARDA contract. The Company is in discussions with BARDA regarding subsequent segments of the contract. 

Operating expenses for the first quarter of 2013 were $8.3 million, compared to $8.6 million for the same period in 2012. Research and development expenses were $6.5 million for the first quarter of 2013, compared to $6.6 million for the same period in 2012. General and administrative expenses were $1.8 million for the first quarter of 2013, compared to $1.9 million for the same period in 2012.

Interest expense was $400,000 in the first quarter of 2013, compared to $100,000 in the same period in 2012. This increase was due to a higher amount of venture debt carried in the first quarter of 2013 compared with the prior year period as a result of a draw-down of a $12.0 million second tranche of venture debt in the third quarter of 2012.

Cash, cash equivalents and short-term investments were $22.9 million at March 31, 2013, compared to $29.8 million at December 31, 2012. Following the completion of Chimerix's recent IPO, the pro forma balance sheet at March 31, 2013, shows $134.1 million in cash, cash equivalents and short-term investments, $14.3 million in debt and 25.7 million outstanding shares of common stock.
