Chimerix Announces Fourth Quarter and Full Year 2016 Financial Results

- Successful Administration of IV Brincidofovir 50 mg in Ongoing Dose Escalation Study -

- Demonstrates Favorable Safety and Tolerability Profile -

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

DURHAM, N.C., March 02, 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 fourth quarter and full year ended December 31, 2016.

"Today we are pleased to report the positive outcome from the third cohort of our Single Ascending Dose study of intravenous brincidofovir, which demonstrated continued safety and tolerability at higher doses and further supports brincidofovir's potential as a potent broad spectrum antiviral," said Garrett Nichols, MD, MS, Chief Medical Officer of Chimerix.

"During 2016 we made considerable progress developing the optimal paths forward for oral brincidofovir for short course treatment and advancing intravenous brincidofovir into the clinic.  These developments have positioned the Company well to achieve a number of milestones throughout 2017 that we believe will be instrumental in advancing brincidofovir in order to benefit patients fighting these serious viral infections," concluded Michelle Berrey, MD, MPH, President and Chief Executive Officer.

The ability to provide brincidofovir (BCV) in oral and intravenous (IV) formulations enables development across multiple indications and populations with the potential for best-in-class efficacy and safety.  In 28-day animal studies and in single dose administration in healthy subjects, IV BCV has shown the potential for less gastrointestinal (GI) injury compared to oral BCV, even with higher plasma drug concentrations and longer-term dosing.  Additionally, data from animal efficacy studies and AdVise support the continued development of oral BCV for short course treatment of smallpox and adenovirus (AdV).

Recent Highlights and Program Updates:

Reported Preliminary Data from Ongoing Phase 1 Dose Escalation Study of IV BCV in Healthy Subjects
In this Phase 1 study, a total of 40 healthy subjects have been randomized to receive either a single dose of IV BCV or IV placebo in one of four cohorts:

  • Cohort 1: IV BCV 10 mg (n=6) or placebo (n=2);
  • Cohort 2: IV BCV 25 mg (n=6) or placebo (n=2);
  • Cohort 3: IV BCV 50 mg given over 2 hours (n=9) or placebo (n=3); and
  • Cohort 4: IV BCV 50 mg given over 4 hours (n=9) or placebo (n=3).

In January 2017, Chimerix announced preliminary data from the first two cohorts of this ongoing Phase 1 study. Today, Chimerix announces preliminary results from the third cohort (IV BCV 50 mg given over 2 hours) of this study.

In this ongoing blinded study, a favorable safety and tolerability profile has been observed in all three cohorts completed to date.  Grade 1-2 (on a scale of Grade 1-5) safety laboratory changes were observed in some subjects in the first three dosing cohorts; none were considered clinically significant. No Grade 3 or higher safety laboratory abnormalities were observed for any subjects receiving IV study drug in Cohorts 1, 2 and 3.  In Cohort 3, IV BCV 50 mg or placebo, mild Adverse Events (AEs) were reported that possibly were related to study drug included: a single lower gastrointestinal event of loose stools was reported in one subject, and two other subjects each reported a mild headache that spontaneously resolved. In addition, three subjects had bruising at the site of the IV catheter. IV BCV 50 mg provided plasma drug exposures higher than achieved with oral BCV dosing, and in the range of exposures targeted for treatment indications such as for BK nephropathy.

Cohort 4 will explore IV BCV 50 mg or placebo over a longer period of infusion.  Complete clinical and pharmacokinetic data from all four cohorts are expected to be reported during the first half of 2017.

Presented Final Data from AdVise Trial at BMT Tandem Meetings

On February 23, final data from the AdVise trial of BCV for the treatment of AdV infection in allogeneic hematopoietic cell transplant (HCT) recipients was presented at the combined annual meetings of the Center for International Blood & Marrow Transplant Research (CIBMTR) and the American Society for Blood and Marrow Transplantation (ASBMT) held February 22-26, 2017 in Orlando, FL.

The AdVise trial was an open-label, multicenter study designed to evaluate the efficacy, safety and overall tolerability of oral BCV for the treatment of AdV infection. Pediatric and adult subjects were assigned to one of three cohorts:

  • Cohort A - allogeneic HCT recipients with asymptomatic or limited AdV infection;
  • Cohort B - allogeneic HCT recipients with disseminated AdV disease; and
  • Cohort C - autologous HCT recipients, solid organ transplant recipients and other patients with serious AdV infections.

All subjects were to receive 12 weeks of oral BCV and were followed for at least 36 weeks.  This final analysis includes 158 allogeneic HCT recipients assigned to Cohorts A (23 adult and 42 pediatric patients) and B (35 adult and 58 pediatric patients).

In the AdVise trial, declines in AdV viral load of ≥2 log10 c/mL or below the limit of detection at week four were observed in 76 percent of pediatric patients and 45 percent of adult patients.  Notably, this antiviral effect was observed even in HCT recipients who did not yet have immune recovery. In Cohort A, 55 percent of patients with baseline low immunity (CD4 counts &#60 50 cells/μL) achieved ≥2 log10 c/mL decline or undetectable AdV at week four. In Cohort B, 52 percent of patients with baseline low immunity achieved ≥2 log10 c/mL decline or undetectable AdV over the same period of time.

In patients with disseminated disease, rapid virologic response, defined as undetectable AdV viremia at week six, was associated with nearly double the survival rate and lower AdV-associated mortality compared with subjects who did not have an antiviral response, as summarized in the table below.

 MortalityAdV-Associated Mortality

Responder*7/28 (25%)p=0.0311/28 (4%)
Non-responder7/13 (54%)2/13 (15%)

Responder*5/10 (50%)p=0.00040/10 (0%)
Non-responder13/14 (93%)10/14 (71%)

* Responders defined as subjects with baseline AdV viremia still on study at week six who had undetectable plasma AdV at week six; non-responders defined as subjects who did not achieve the specified cut-off. A Cox model was used to compare mortality at 36 weeks in responders and non-responders.

Diarrhea was the most commonly reported treatment-emergent adverse event in AdVise Cohorts A and B, reported at 38 percent of adult and 43 percent of pediatric HCT recipients. Treatment discontinuations related to diarrhea in Cohorts A and B occurred in 5 percent of adult and 6 percent of pediatric patients.
