DURHAM, N.C., Nov. 07, 2016 (GLOBE NEWSWIRE) -- Chimerix (NASDAQ:CMRX), a biopharmaceutical company developing novel antivirals to address unmet medical needs, today reported financial results and provided a corporate update for the third quarter ended September 30, 2016.

"We are optimistic about 2017 and believe our novel intravenous formulation of brincidofovir may prove to be the optimal way to prevent or treat DNA viral infections, by achieving effective drug levels in the plasma and infected organs while avoiding gastrointestinal side-effects," said M. Michelle Berrey, MD, MPH, President and CEO of Chimerix.  "In addition, the learnings from AdVise, specifically the stepwise reduction in mortality observed in pediatric patients as the study progressed, underscore the potential for oral brincidofovir in these patients with life-threatening adenovirus infection.  A shorter time from diagnosis to first dose of brincidofovir is thought to be a significant driver of the observed improvement.  Early identification of adenovirus and intervention with brincidofovir are being incorporated in the design of our next comparative trial of oral brincidofovir which we expect to initiate in 2017.  Additionally, we are excited to announce CMX521 from the Chimerix Chemical Library as our lead clinical candidate for the treatment of norovirus."

Recent Highlights and Program Updates:

Development of Intravenous Brincidofovir Formulation ContinuesChimerix remains on track to provide pharmacokinetic, safety and tolerability data from a single dose escalation study of intravenous (IV) brincidofovir in early 2017, with multiple dose studies in patients with active viral infection to follow.  In preclinical testing, animals given four weeks of  IV brincidofovir showed no signs of gastrointestinal injury, even at plasma exposures several fold higher than those ever achieved with oral dosing.  If these early clinical studies of IV-administered brincidofovir continue to demonstrate low or no gastrointestinal side-effects, IV brincidofovir could be in late-stage registrational studies in 2018.  Once brincidofovir enters the target cells and is converted to the active antiviral, the drug remains at effective concentrations for several days, potentially allowing for once-weekly dosing.  The potential to provide higher drug exposures may allow a much-needed treatment for cytomegalovirus (CMV), adenoviruses (AdV), BK virus, and other DNA viral infections, potentially even in difficult to reach anatomical regions such as the brain.

Detailed 24-Week Data from AdVise Study Presented at IDWeek TM In October 2016, Chimerix announced the presentation of detailed 24-week interim results from the AdVise trial of brincidofovir for the treatment of AdV infection in allogeneic hematopoietic cell transplant (HCT) patients.

Building upon the Company's 24-week top-line data announced in May 2016, the presentation at IDWeek highlighted that treatment with brincidofovir generally resulted in robust declines in AdV viral loads. Furthermore, rapid reductions in AdV viremia correlated with improved survival in both adults and pediatric patients.  In an analysis of the data based on enrollment in the trial, a stepwise reduction in mortality was observed as the study progressed: 60% mortality was observed in the initial quarter of pediatric patients enrolled in AdVise, with steady declines to 14% mortality for those patients enrolled in the last quartile.  A shorter time from diagnosis to first dose of brincidofovir is thought to be a significant driver of the observed improvement.

Chimerix currently expects to present final 36-week data from the AdVise trial at a medical meeting during the first quarter of 2017.

Additional evidence regarding the need for a broad spectrum antiviral was presented at IDWeek by Dr. Josh Hill and colleagues.  An analysis of over 400 HCT recipients from the Fred Hutchinson Cancer Research Center showed that quantity and duration of viremia for CMV, AdV, EBV, HHV6 or BK correlated with mortality.  The authors concluded that improved strategies to prevent reactivation of these viruses are needed to improve transplant outcomes.

Continuing Demand for Brincidofovir through our Expanded Access ProgramsThe Company continues to receive requests for brincidofovir via our expanded access programs.  Through the first ten months of 2016, the Company has granted 263 requests for AdV alone, highlighting the unmet need in this area.

Brincidofovir for Smallpox The development of brincidofovir for smallpox continues in collaboration with the Biomedical Advanced Research and Development Authority (BARDA). Following completion of the second animal efficacy study, the Company plans to meet with the FDA to discuss any additional required data for a regulatory decision.  Earlier in 2016, Chimerix provided regulators with a summary of the clinical safety and tolerability of the intended three week course of oral brincidofovir in healthy adults and immunocompromised adults and children.  In addition, the final study report for the rabbitpox efficacy study of brincidofovir has been submitted to the FDA.

In October 2016, Chimerix was notified that the European Medicines Agency's Committee for Orphan Medicinal Products issued a positive opinion for an Orphan Designation for brincidofovir for the treatment of smallpox.

Clinical Candidate CMX521 for Norovirus Chimerix is currently conducting final preclinical studies of a novel norovirus antiviral, designated CMX521, that are required to file an Investigational New Drug application (IND).  CMX521 is a nucleoside analog identified from the Chimerix Chemical Library which targets the norovirus polymerase, a part of the virus that is common to all strains and is required for viral replication.  It is therefore expected to be active against the multiple genetically diverse norovirus strains that circulate each year and cause disease in humans.

In addition to the approximately 20 million acute cases of norovirus that occur each year in the U.S., chronic norovirus infection is increasingly being diagnosed in immune compromised patients.  Approximately 15-20 percent of HCT and SOT recipients are diagnosed with norovirus within the first year after transplant, a diagnosis that has been associated with chronic diarrhea, electrolyte disturbances, and graft rejection.  The Company plans to file an IND for CMX521 in 2017, which, upon acceptance, would enable clinical testing.

Third Quarter 2016 Financial Results

Net loss narrowed to $17 million, or $0.37 per basic and diluted share, for the third quarter of 2016 compared to a net loss of $32.4 million, or $0.70 per basic and diluted share during the same period in 2015.

Revenues for the third quarter of 2016 decreased to $0.7 million compared to $2.3 million for the same period in 2015. Revenue during these periods related to reimbursable expenses associated with the Company's ongoing development contract with BARDA.

Research and development expenses decreased to $12.2 million for the third quarter of 2016, compared to $26.5 million for the same period in 2015. This decrease was primarily due to a decrease in the Company's clinical trial expenses associated with the completion of the Phase 3 SUPPRESS and AdVise trials and close-out of the kidney trials, partially offset by an increase in costs related to the development of the IV formulation of brincidofovir and the conduct of the Expanded Access Programs.

General and administrative expenses decreased to $5.8 million for the third quarter of 2016, compared to $8.5 million for the same period in 2015. The decrease was primarily due to a decrease in commercialization expense.

Loss from operations was $17.4 million for the third quarter of 2016, compared to a loss from operations of $32.7 million for the same period in 2015. The narrowed loss was primarily due to decreased research and development expenses, and general and administrative expenses, as previously discussed.

Chimerix's balance sheet at September 30, 2016 included $288.3 million of capital available to fund operations, no debt, and approximately 46.3 million outstanding shares of common stock.
