DURHAM, N.C., May 10, 2013 (GLOBE NEWSWIRE) -- Chimerix, Inc. (Nasdaq:CMRX), a biopharmaceutical company developing novel, oral antivirals in areas of high unmet medical need, today announced two oral presentations related to its broad-spectrum antiviral compound CMX001 at the International Society for Antiviral Research's 26th International Conference on Antiviral Research (ICAR). ICAR is being held May 11-15, 2013 at the Hyatt Regency in San Francisco, CA.

Chimerix's first presentation will describe the technology underlying Chimerix's two clinical-stage nucleoside phosphonates, CMX001 and CMX157, as well as the potential application of the technology to other compounds in the Chimerix Chemical Library. Chimerix's second presentation describes the emerging cytomegalovirus (CMV) resistance profile for CMX001.  Notably, viral resistance to CMX001 is slow to emerge in vitro and was not observed in treatment-naïve patients enrolled in Chimerix's Phase 2 trial of CMX001 for the prevention of CMV in hematopoietic stem cell transplant (HSCT) recipients.  

Together, these results support the use of CMX001 as first-line anti-CMV therapy and the continued development of CMX001 for prevention of CMV in Chimerix's upcoming Phase 3 trial, SUPPRESS.

About CMX001

Chimerix's lead product candidate, CMX001, is a broad-spectrum oral nucleotide analog that blocks replication of all five families of double-stranded DNA (dsDNA) viruses that infect humans, including CMV, adenovirus (AdV), BK virus and herpes simplex viruses.  In a Phase 2 trial, CMX001 demonstrated potential clinical utility in prevention of CMV infection in high-risk patients who had received a HSCT.  Chimerix anticipates initiating SUPPRESS, its Phase 3 trial of CMX001 for the prevention of CMV infection in adults undergoing HSCT, in mid-2013.  In December 2012, Chimerix completed enrollment of a Phase 2 trial in pediatric and adult HSCT recipients evaluating CMX001 as a preemptive therapy for AdV disease, an often-fatal infection with no approved therapies.  Since 2009, Chimerix has made CMX001 available through a Compassionate Use Program to over 80 medical centers worldwide for the treatment of over 430 patients with life-threatening dsDNA viral infections and no alternative treatment.

Chimerix has received Federal funding for the development of CMX001 as a potential medical countermeasure against smallpox from the Biomedical Advanced Research and Development Authority, Office of the Assistant Secretary for Preparedness and Response, Office of the Secretary, Department of Health and Human Services, under Contract No. HHSO100201100013C.

About Chimerix

Chimerix is committed to the discovery, development and commercialization of novel, oral antiviral therapeutics designed to transform patient care in areas of high unmet medical need.  Chimerix's proprietary lipid technology has given rise to two clinical-stage lipid acyclic nucleoside phosphonates, CMX001 and CMX157, which have demonstrated the potential for enhanced activity and safety in convenient, orally administered dosing regimens.  Chimerix's second product candidate, CMX157, an oral nucleotide analog lipid-conjugate for the treatment of HIV infection, was licensed to Merck in July 2012.
