DURHAM, N.C., Oct. 05, 2018 (GLOBE NEWSWIRE) -- Chimerix (NASDAQ:CMRX), a biopharmaceutical company developing novel antivirals to address unmet medical needs, today announced data from the company’s Phase 1 study evaluating the safety and pharmacokinetics (PK) of multiple ascending doses (MAD) of intravenous (IV) brincidofovir (BCV) in healthy subjects. These data will be presented at IDWeek™ 2018, held October 3-7 in San Francisco, CA.
“This study shows that four weekly or twice-weekly doses of the IV formulation of brincidofovir are generally well tolerated, and the 10 mg dose provides similar blood levels as the oral 100 mg dose with no reported gastrointestinal side effects,” said Garrett Nichols, MD, MS, Chief Medical Officer of Chimerix. “We have now opened two additional studies in stem cell transplant recipients in the U.S. and EU to confirm these promising results.”
The Phase 1 study evaluated the safety and pharmacokinetics of IV BCV in 27 healthy individuals who were randomized 3:1 to receive IV BCV or placebo in sequential MAD cohorts. Individuals receiving IV BCV were given a 10 mg dose in a two-hour infusion twice a week for two weeks or a 20 mg dose in either a one- or two-hour infusion once a week for four weeks. Twice weekly doses of IV BCV at 10 mg provided similar blood levels of the drug as the oral BCV 100 mg dose previously studied in late-stage clinical trials, with no reported diarrhea or other gastrointestinal adverse events.
Other key findings include:
- Both doses of IV BCV were generally safe and well tolerated.
- No serious adverse events were reported; mild adverse events with 10 mg dose included headache and bruising at IV site of injection.
- Brincidofovir exposure was dose-proportional and no accumulation was observed.
- Mild alanine aminotransferase (ALT) increases were reversible upon cessation of drug, and were not associated with hyperbilirubinemia, as seen with oral BCV.
