DURHAM, N.C., May 09, 2017 (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 first quarter ended March 31, 2017.

"We have made meaningful progress advancing both the short-course oral brincidofovir program and the first of several confirmatory studies of IV brincidofovir. The single ascending dose study of IV brincidofovir (BCV) demonstrated with the first dose of 10 mg that we can achieve the plasma exposures that previously showed antiviral activity in the SUPPRESS and AdVise studies, but without the previously noted gastrointestinal (GI) limitations," said M. Michelle Berrey, MD, MPH, President and CEO of Chimerix. "These results together with the multiple-dose studies in healthy subjects and in infected populations will inform the planned pivotal pediatric trial for IV BCV, the MVP-Peds Study ( Multi- Viral Prevention in Pediatric Allogeneic Transplant Recipients), which we hope to initiate in 2018.  We look forward to advancing this important program to bring brincidofovir to immunocompromised patients suffering with these life-threatening viral infections."                                          Recent Highlights and Program Updates:

Full Data from Phase 1 Dose Escalation Study of Intravenous Brincidofovir in Healthy Subjects Reported

Data from all four cohorts of the Phase 1 study of IV BCV were presented at the recent Investor Event held on April 27, 2017. In this study a total of 40 healthy subjects were randomized to receive a single dose of either IV BCV or IV placebo in one of four cohorts. IV BCV 10 mg achieved comparable plasma exposure to that achieved with the oral BCV 100 mg dose.  There were no drug-related adverse events (AEs) reported in either the 10 mg or 25 mg cohorts; this dose range is likely to be selected for future studies for treatment of adenovirus and prevention of cytomegalovirus and other DNA viruses based on the antiviral activity demonstrated with oral BCV 100 mg. 

Doses higher than those currently being explored for the above indications ("supratherapeutic") of IV BCV (50 mg given over two hours in Cohort 3, 50 mg given over four hours in Cohort 4) were also administered to evaluate the potential effects of BCV on QT interval and other safety parameters.  A majority of the AEs reported were mild and self-limited. Four subjects in Cohort 3 reported drug-related AEs: one drug-related GI AE, two subjects with a mild headache, and one subject reported pain and irritation at the IV infusion site.  In Cohort 4, five subjects reported nine drug-related AEs: three subjects with GI AEs, two subjects with headache, and one subject with reversible elevations of liver transaminases reported as an AE. 

Therapeutic doses of IV BCV were thus very well tolerated, and no new adverse events were identified with the IV formulation of BCV compared with the large safety database for oral BCV.

Clinical Development of BCV Continues

Following discussions with European regulators, Chimerix plans to initiate the AdAPT trial ( Adenovirus after Allogeneic Pediatric Transplantation, previously referred to as "Study 999") with short-course oral BCV later this year in Europe, and possibly in the US.  AdAPT will recruit approximately 140 patients.  Children who have received a T-cell depleted allogeneic HCT with confirmed AdV viral DNA loads greater than 1000 c/ml in plasma within 100 days from transplant will be randomized to receive oral BCV or local standard of care which is predominantly off-label cidofovir.  The study builds on the scientific understanding from multiple previous trials of BCV in patients with life-threatening AdV infection, and will provide comparative data on short-course oral BCV compared with currently available treatment. If positive, data from AdAPT could enable regulatory approval in Europe for oral BCV. 

Following on the encouraging data from the single ascending dose study of IV BCV, Chimerix plans to initiate a multiple ascending dose study of IV BCV in healthy subjects, and a second study to generate multiple-dose PK and safety data in virally infected patients. These data are intended to inform the planned pivotal study of Multi- Viral Prevention of DNA viral infections in pediatric HCT recipients (MVP-Peds).  Subject to the successful completion of the multiple ascending dose study, Chimerix intends to initiate the MVP-Peds study during 2018.

Development of BCV for smallpox continues in collaboration with the Biomedical Advanced Research and Development Authority (BARDA). Following completion of a planned second animal efficacy study, Chimerix plans to meet with the FDA to discuss any additional required data for a regulatory decision.

Investor Event

On April 27, 2017, Chimerix hosted an Investor Event that featured keynote presentations from Thomas Lion, MD, PhD, Professor and Medical Director of the Children's Cancer Research Institute (Vienna, Austria), who discussed the rapidly changing field of adenovirus infections in immunocompromised patients, and highlighted the need for new therapeutic options that can facilitate viral control during periods of severe immunosuppression.  Dr. Lion presented research showing that adenovirus often reactivates in the gut and that early treatment can lead to significantly improved outcomes.  Joshua Hill, MD, Associate in the Vaccine and Infectious Disease Division at the Fred Hutchinson Cancer Research Center (Seattle, Washington) shared his research on the frequency of multiple viral infections in both adult and pediatric transplant recipients.  Dr. Hill showed that 90% of the predominately adult allogeneic HCT recipients whose samples were tested at their center had evidence of at least one DNA virus, and two-thirds had two or more DNA viruses.  Of the HCT recipients who reactivated CMV, more than three-quarters had at least one other DNA virus identified and were at an increased risk of death.  These data demonstrate a need for novel strategies to prevent multiple DNA viral infections and their negative impact on patient outcomes. Genovefa Papanicolaou , MD, Infectious Disease Specialist at Memorial Sloan Kettering Cancer Center (New York, NY) also spoke of her experiences with multiple DNA viruses in her allogeneic transplant recipients, which corroborated Dr. Hill's data.
