Chimerix Initiates AdAPT Study for Oral Brincidofovir and Advances IV Brincidofovir to Patient Studies
- Pivotal AdAPT Study of Oral Brincidofovir for Adenovirus Now Enrolling -
- No GI Adverse Effects for IV Brincidofovir 10 mg -
- Announces First Antiviral Specific for Norovirus Now In Clinical Testing -
“We are especially pleased to begin 2018 with the initiation of AdAPT, a comparative study designed together with European regulators to demonstrate the superiority of brincidofovir’s antiviral effect in pediatric transplant recipients facing life-threatening adenovirus infection. As we’ve seen in multiple other settings, clearance of adenovirus has a positive impact on survival in the first year after transplant. Positive data from AdAPT is expected to provide the basis for a European marketing approval, and if clinical benefits are confirmed, could be considered for an accelerated approval under the FDA’s Subpart H guidance. Our team is committed to fulfilling the promise of brincidofovir and its potential as the first approved antiviral for adenovirus infections,” stated
“We are also happy to report successful administration of 2-4 weeks of IV BCV without dose-limiting gastrointestinal events, supporting the progression to Phase 2 studies of IV BCV in virally infected transplant recipients. Specifically, twice-weekly doses of IV BCV 10 mg provide similar blood levels of the drug as the oral BCV 100 mg dose previously studied in late-stage trials, but did not result in any reported diarrhea. Proposals for these Phase 2 studies of IV BCV in virally-infected patients are currently being reviewed by regulators in
“And finally, our new molecule, CMX521, is the first direct-acting antiviral for norovirus to progress to clinical-stage development. We look forward to sharing more on this compound as we complete initial clinical assessments,” concluded Dr. Berrey.
Initiation of AdAPT Study of Oral Brincidofovir in Adenovirus
The Company reports the initiation of the AdAPT Study (Adenovirus after Allogeneic Pediatric Transplantation). This study is targeting enrollment of 141 pediatric allogeneic hematopoietic stem cell transplant (HCT) recipients with confirmed adenovirus (AdV) infection; patients will be randomized 2:1 to receive short-course oral BCV or local standard-of-care (SOC) treatment at approximately 30 sites in
The primary endpoint of the study is a comparison of the average adenovirus viral burden (as measured by AdV DNA levels in blood) over 16 weeks in subjects treated with short-course oral BCV versus those who receive local SOC. The study is 90% powered to show the superiority of reduced adenoviral burden in brincidofovir-treated patients compared to SOC. The study will also evaluate the correlation of AdV burden (and its clearance) with clinical outcomes including survival. Enrollment is estimated to complete in 2019.
IV Brincidofovir Progresses to Phase 2 Studies
The Company announces the successful completion of the multiple ascending dose (MAD) study of IV BCV in healthy subjects. This study evaluated the safety, tolerability and pharmacokinetics of IV BCV 10 mg given twice weekly and IV BCV 20 mg given once weekly in healthy subjects for two to four weeks. IV BCV was well-tolerated at all dose levels, with no dose-limiting clinical adverse events. Importantly, there was no diarrhea reported for IV BCV 10 mg dosed twice weekly, a dose that provides drug levels equivalent to oral BCV 100 mg which demonstrated antiviral activity in previous late-stage clinical studies. Proposals for studies of IV BCV in virally-infected patients have progressed to regulatory review in

This press release includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that are subject to risks, uncertainties and other factors, including the possibility that there may not be a viable continued development path for brincidofovir, that FDA and other regulatory authorities may not approve brincidofovir or brincidofovir-based regimens, and that marketing approvals, if granted, may have significant limitations on their use. As a result, brincidofovir may never be successfully commercialized. In addition, Chimerix may be unable to file for regulatory approval for brincidofovir with other regulatory authorities. Similar risks and uncertainties apply to the Company’s development of CMX521.These risks, uncertainties and other factors could cause actual results to differ materially from those expressed or implied by such forward-looking statements. Risks are described more fully in the Company's filings with the Securities and Exchange Commission, including without limitation the Company's most recent Quarterly Report on Form 10-Q and other documents subsequently filed with or furnished to the Securities and Exchange Commission. All forward-looking statements contained in this press release speak only as of the date on which they were made.
