Topline Data from SUPPRESS Trial of Brincidofovir for Prevention of Cytomegalovirus in Hematopoietic Cell Transplant Recipients Anticipated in Early 2016
Dosing Initiated in Phase 3 SUSTAIN and SURPASS Trials of Brincidofovir for Prevention of Cytomegalovirus Disease in Kidney Transplant Recipients
DURHAM, N.C., Nov. 5, 2015 (GLOBE NEWSWIRE) -- Chimerix (NASDAQ:CMRX), a biopharmaceutical company developing novel, oral antivirals to address unmet medical needs, today reported financial results and provided a corporate update for the third quarter of 2015.
M. Michelle Berrey, MD, MPH, President and CEO, said, “We continue to make significant progress in our clinical development programs. After completing enrollment in our pivotal SUPPRESS trial in June for the prevention of clinically significant cytomegalovirus (CMV) infection in patients undergoing hematopoietic cell transplant (HCT), we have now initiated our Phase 3 SUSTAIN and SURPASS trials of brincidofovir for prevention of CMV disease in kidney transplant recipients. We remain keenly focused on delivering topline data from SUPPRESS in early 2016, preparing the New Drug Application (NDA), and continuing our commercial prelaunch initiatives for brincidofovir, which, if approved, would be the first and only therapy for the prevention of CMV in these patients who are immunocompromised following HCT.”
Recent Company Highlights
- Dosing Initiated in Phase 3 SUSTAIN and SURPASS Trials of Brincidofovir for Prevention of Cytomegalovirus Disease in Kidney Transplant Recipients
In October 2015, the company initiated dosing in its Phase 3 kidney transplant program. The SUSTAIN and SURPASS trials are evaluating brincidofovir for the prevention of CMV disease in kidney transplant recipients.
SUSTAIN is designed to demonstrate the safety and efficacy of brincidofovir for the prevention of CMV disease in kidney transplant recipients at high risk of CMV disease. It is a blinded, non-inferiority study of brincidofovir versus valganciclovir in kidney transplant recipients who have not been previously infected with CMV (CMV seronegative recipient, or “R-") and who have no immunity to CMV. These CMV seronegative patients who receive a kidney from a CMV seropositive (“D+") donor are at high risk of CMV infection and disease. The trial is expected to enroll approximately 750 patients with 1:1 randomization to brincidofovir or valganciclovir for 200 days following the transplant.
SURPASS is a blinded study of brincidofovir versus valganciclovir in kidney transplant recipients who are CMV seropositive (“R+"). These CMV seropositive patients are at an increased risk of CMV disease. The trial is expected to enroll approximately 520 patients with 1:1 randomization to brincidofovir or valganciclovir for 100 days following the transplant.
The primary endpoint of both studies is CMV disease, with secondary endpoints related to renal function, a measurement closely correlated with long-term kidney graft survival. The same dose of brincidofovir that was studied in the SUPPRESS trial in HCT recipients, 100 mg twice-weekly, will be studied in the SUSTAIN and SURPASS trials.
- BARDA Contract Extension of $13 Million for the Continued Development of Brincidofovir for Smallpox
In September 2015, the company executed an extension of its contract with the Biomedical Advanced Research and Development Authority (BARDA) for the development of brincidofovir as a medical countermeasure to treat smallpox. This latest contract extension provides approximately $13 million in additional funding. The company initiated the development contract with BARDA in February 2011 to support early research and development of brincidofovir in animal models of smallpox.
- Completed Enrollment of Brincidofovir AdVise Trial for the Treatment of Adenovirus Infection
In August 2015, the company completed enrollment of its AdVise trial, which is evaluating brincidofovir for the treatment of adenovirus (AdV) infections in pediatric and adult patients. The AdVise trial enrolled over 200 patients with serious adenovirus infections, including patients in the key population of HCT recipients with disseminated AdV disease, a life-threatening infection that has reported mortality of up to 80%. HCT recipients with localized or asymptomatic AdV infection were also enrolled in AdVise, as were patients with other reasons for immune suppression that had confirmed serious adenovirus infections, a group that included solid organ transplant recipients and patients receiving chemotherapy. All patients enrolled in AdVise receive brincidofovir orally twice-weekly for 12 weeks, and are followed up to 24 weeks after treatment, with a primary endpoint of overall survival. The company is also conducting Study 305 to obtain clinical outcomes data in patients considered matched controls from the same medical centers as AdVise participants. As the company’s initial NDA submission will be CMV only, the company now plans to conduct the adenovirus analysis at study conclusion, when all subjects have completed 24 weeks of follow-up after dosing with brincidofovir. The company will continue to prepare data from the AdVise trial and the historical matched controls to review with the FDA to determine the regulatory pathway for the treatment of adenovirus. Release of final results of the AdVise trial with matching controls is planned for the second half of 2016.
- Brincidofovir Demonstrated a Statistically Significant Survival Benefit in a Pivotal Study in an Animal Model of Smallpox Infection
In July 2015, the company reported positive results from the pivotal smallpox study that was conducted under the FDA’s Animal Efficacy Rule, which allows for testing of investigational drugs in animal models to support effectiveness in diseases which are not ethical or feasible to study in humans. In this well-characterized model of smallpox, animals were administered a lethal inoculum of rabbitpox virus, and monitored for clinical signs of disease. Following the onset of the first clinical sign of disease, animals were randomized to receive placebo, immediate brincidofovir, or brincidofovir after a delay of 24, 48, or 72 hours. The study met its primary endpoint of survival benefit with 100% of the animals that received brincidofovir immediately following the confirmation of their first clinical sign of infection surviving the disease. Further, animals treated with brincidofovir 24 or 48 hours following the first clinical sign of disease also demonstrated a statistically significant (p<0.05) reduction in mortality compared to animals that received placebo.
Third Quarter 2015 Financial Results
Chimerix reported a net loss of $32.4 million, or $0.70 per basic and diluted share, for the third quarter of 2015. During the same period in 2014, the company recorded a net loss of $17.0 million, or $0.47 per basic and diluted share.
Revenues for the third quarter of 2015 increased to $2.3 million compared to $1.2 million for the same period in 2014, due to an increase in the third quarter of 2015 in reimbursable expenses associated with the company’s ongoing development contract with BARDA.
Research and development expenses increased to $26.4 million for the third quarter of 2015, compared to $13.3 million for the same period in 2014. This increase was primarily due to the effect of costs related to the ongoing Phase 3 SUPPRESS trial and the AdVise trial, as well as costs for the Phase 3 SUSTAIN and SURPASS trials, and growth of the company’s clinical, regulatory, development, and manufacturing groups.
General and administrative expenses increased to $8.6 million for the third quarter of 2015, compared to $4.7 million for the same period in 2014. The increase was primarily due to increased commercialization and compensation expense and the growth in the company’s infrastructure.
Loss from operations was $32.7 million for the third quarter of 2015, compared to a loss from operations of $16.9 million for the same period in 2014. The variance was primarily due to the increased research and development, and general and administrative expenses, as previously discussed.
Chimerix’s balance sheet at September 30, 2015 included $378.4 million of capital available to fund operations, $0.4 million in debt and approximately 46.1 million outstanding shares of common stock.

About Brincidofovir
Chimerix’s lead product candidate, brincidofovir, is an oral nucleotide analog that has shown in vitro antiviral activity against all five families of DNA viruses that affect humans, including the herpesviruses and adenovirus. Brincidofovir has not been associated with kidney or bone marrow toxicity in over 1,000 patients treated to date. Based on the clinically and statistically significant Phase 2 results in CMV prevention, Chimerix initiated the 450 patient Phase 3 SUPPRESS trial, which completed enrollment in June 2015. If positive, data from SUPPRESS will support Chimerix’s initial regulatory submission for brincidofovir for the prevention of CMV infection in adult HCT recipients. Chimerix is also conducting AdVise, a trial in patients with adenovirus infection, an often-fatal viral infection with no approved treatment; AdVise completed enrollment in August 2015. Chimerix initiated dosing in the two Phase 3 SUSTAIN and SURPASS trials in recipients of kidney transplants, a population that continues to have unmet medical need in prevention of CMV. Chimerix is working with BARDA to develop brincidofovir as a medical countermeasure against smallpox. Brincidofovir has received Fast Track designation from the FDA for CMV, adenovirus, and smallpox.
