About Brincidofovir (CMX001)

Chimerix's lead product candidate, brincidofovir (CMX001), is an oral nucleotide analog that has shown broad-spectrum antiviral activity against all five families of double-stranded DNA (dsDNA) viruses that affect humans, including cytomegalovirus (CMV), adenovirus (AdV), BK virus (BKV) and herpes simplex viruses. Brincidofovir has a favorable safety and tolerability profile, with no evidence of kidney or bone marrow toxicity in nearly 900 patients dosed with brincidofovir to date. Chimerix believes that brincidofovir has the potential to be the first broad-spectrum antiviral for the prevention and treatment of clinically significant infections and diseases caused by dsDNA viruses.

Following positive Phase 2 results, in the third quarter of 2013 Chimerix initiated the Phase 3 SUPPRESS trial which will support Chimerix's initial regulatory submission for prevention of CMV infection in adult hematopoietic cell transplant (HCT) recipients. Chimerix recently presented results from its Phase 2 trial in adenovirus, an often-fatal infection with no approved treatment. A brincidofovir dose of 100 mg twice weekly demonstrated a significant antiviral effect on levels of AdV in the blood, and a numeric decrease in overall mortality. Chimerix continues to work with the Biomedical Advanced Research and Development Authority (BARDA) to develop brincidofovir as a medical countermeasure against smallpox.

About the Phase 3 SUPPRESS Trial

SUPPRESS is designed to demonstrate the efficacy and safety of brincidofovir for the prevention of CMV infection versus a placebo control, as no therapy is currently approved for the prevention of CMV in HCT recipients. The primary endpoint for SUPPRESS is the rate of clinically significant CMV infection through the first 24 weeks post-transplant. The trial is powered to detect a relative 50% decrease in clinically significant CMV infection in subjects receiving brincidofovir versus those receiving placebo. Secondary endpoints in the SUPPRESS trial include clinical and virologic evidence of dsDNA viral infections, including AdV, BKV, and other herpesviruses such as HHV-6 and varicella zoster virus, which contribute to morbidity and mortality in the first year following HCT.

SUPPRESS is anticipated to enroll approximately 450 HCT recipients who are at increased risk of CMV infection, with approximately 300 subjects receiving 100 mg twice weekly brincidofovir and 150 receiving placebo (2-to-1 ratio). Approximately 40 transplant centers will participate in SUPPRESS. Dosing of study drug will begin shortly after subjects receive their transplant, and will not require evidence of stem cell "engraftment" (evidence of production of blood cells by the new transplant), a safety precaution incorporated in the Phase 2 trial of brincidofovir and other recent trials of investigational antivirals for CMV prevention. Enrolled subjects will continue on brincidofovir or placebo through Week 14 post-transplant, the period of highest risk for viral reactivation. Subjects will continue to be monitored for evidence of CMV and other dsDNA viral infections through Week 24 post-transplant.

Data from SUPPRESS are anticipated in 2015 and, if positive, may support Accelerated Approval of brincidofovir for the prevention of CMV infection.
