Chimerix Announces Third Quarter 2018 Financial Results

- Conference Call at 8:30 a.m. ET Today -

DURHAM, N.C., November 8, 2018 -- Chimerix (NASDAQ:CMRX), a biopharmaceutical company developing novel antivirals to address life-threatening viral infections, today reported financial results and provided a corporate update for the third quarter ended September 30, 2018.

“We have made important progress throughout the year that we believe will position Chimerix for several transformational catalysts in 2019. We expect AdAPT to fully enroll in 2019 and provide data in 2020. Data from our Phase 2 studies of IV BCV should inform the design and doses of BCV in other viral infections such as BK virus and HHV-6. Results from our pivotal animal studies supporting BCV for smallpox are anticipated in 2019. Finally, our financial position remains strong, providing the capital needed to advance our clinical programs for BCV and CMX521,” said M. Michelle Berrey, MD, MPH, President and Chief Executive Officer of Chimerix.

Recent Highlights and Program Updates:

Detailed AdVance Data Presented at IDWeek

At IDWeek 2018 in early October, Chimerix presented the full analysis of multiple measures of adenovirus (AdV) viral load dynamics from the AdVance study. AdVance was the first large, multi-center study of AdV incidence, natural history, management and clinical outcomes in allogeneic hematopoietic cell transplant (allo-HCT) recipients.

The analysis considered six different dynamic measures of AdV viral load and their association with all-cause mortality. Importantly, all measures were independently associated with mortality, including the viral burden measured as time-averaged area-under-the-curve for AdV viral load over 16 weeks (AAUC0-16). As with many viral infections, peak viral load and the duration of the high viral load were both predictors of poor clinical outcomes. The area-under-the-curve includes both measures: viral peak and persistence. As the primary endpoint in the ongoing AdAPT study, the company believes AdV AAUC0-16 is thus likely to reflect the superior antiviral effect of oral brincidofovir (BCV) compared with current standard of care and may also demonstrate the improved short-term outcomes in subjects who are treated with oral BCV. 

Data from Multiple Ascending Dose Study of IV Brincidofovir Presented at IDWeek

Chimerix presented data from the company’s Phase 1 study evaluating the safety and pharmacokinetics (PK) of multiple ascending doses (MAD) of intravenous (IV) BCV in healthy adult subjects. These data were presented at IDWeek 2018.

The study evaluated the safety and PK of four doses of IV BCV in 27 healthy individuals who were randomized 3:1 to receive IV BCV or placebo in sequential cohorts of escalating doses. 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.

Preclinical Data Demonstrating Antiviral Activity of BCV Against Polyomavirus Presented at Kidney Week 2018

Chimerix announced data from two preclinical studies which assessed the in vivo antiviral activity of BCV against polyomavirus. These data were presented at the American Society of Nephrology’s Kidney Week 2018 in San Diego, CA.

The two studies evaluated BCV’s effect against Murine Polyoma Virus (MuPyV), a mouse polyomavirus closely related to the human BK virus. In these studies, mice with MuPyV were treated with BCV either 24 hours after being infected or prophylactically for a full week prior to infection. Data from the two studies show that BCV demonstrated significant antiviral activity against MuPyV and showed no safety signals across BCV doses administered. In mice treated after infection with MuPyV, BCV delivered via intraperitoneal injection once daily, twice weekly or once weekly reduced kidney viral loads by 100-fold relative to placebo. These data along with data from the company’s ongoing Phase 2 studies of IV BCV are expected to inform the dose regimen for the company’s planned Phase 2/3 studies.

Program Updates

Oral BCV

The AdAPT Study (Adenovirus after Allogeneic Pediatric Transplantation) is open for enrollment in the United States (US) and Europe.  All targeted countries and clinical sites are anticipated to be open for enrollment by the end of 2018. Chimerix anticipates completing enrollment in 2019 and obtaining results from the 16‑week primary endpoint in 2020; however, this forecast will likely be updated once the company has several months of data on the enrollment rate from a majority of planned clinical centers.

IV BCV Phase 2 Studies Continue to Initiate in the US and Europe

Sites in the US and Europe continue to open for enrollment in our IV BCV Phase 2 studies in adult allo-HCT recipients with AdV. The company anticipates interim data in 2019. Building on the recently-presented data from IV BCV in healthy adults, the safety and BCV levels in patients, together with AdV viral decay curves, will inform the design of future Phase 2/3 studies.

Final Animal Studies for Brincidofovir for the Treatment of Smallpox

Chimerix recently initiated the adjunct rabbit study and anticipates initiating the pivotal mouse efficacy study in 2019. Data from both animal efficacy models are expected in 2019. Chimerix intends to submit marketing applications for oral BCV for smallpox following the completion of the rabbit and mouse efficacy studies.

CMX521 for Norovirus

In September 2018, Chimerix presented data on CMX521 at the European Society for Clinical Virology in Athens, Greece. The data presented included:
No safety concerns were identified with single oral doses of CMX521 up to 2400 mg the top dose tested
CMX521 plasma exposures increased in a less-than-proportional manner with escalating single oral dose administration

Clinical testing of CMX521 is ongoing in conjunction with in vitro studies in cultured human intestinal cells and recently described animal models of norovirus to assess antiviral efficacy.
