Chimerix Announces First Quarter 2019 Financial Results and Strategy Update

- Reports Positive Top-line Survival Data from Pivotal Mouse Study as Key Milestone on Path to Smallpox Regulatory Submission -

- Plan to Focus on Execution of Smallpox Program, Halting All Other Brincidofovir Development Activities -

- Restructuring to Reduce Workforce by More Than 50%, Maintaining Key Capabilities and Preserving Capital for New Programs -

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

DURHAM, N.C., May 9, 2019 -- Chimerix (NASDAQ:CMRX), today reported financial results for the first quarter ended March 31, 2019 and provided an update on corporate strategy. Chimerix announced positive top-line results from the in-life portion of the mousepox study with ectromelia virus (ECTV), the Company’s second animal model under the Food and Drug Administration (FDA) Animal Efficacy Rule. In addition, Chimerix announced the discontinuation of all ongoing human clinical trials for oral and intravenous brincidofovir (BCV) due to low patient accrual across all active trials. Reflecting these developments, Chimerix plans to undertake a corporate restructuring, including a greater than 50% reduction in staff. The Company intends to pursue external opportunities to build its pipeline of product candidates.

“We’re very pleased to now have shown significant improvements in survival, the primary endpoint in both the rabbitpox and mousepox animal models. This is a key milestone on the path toward an anticipated 2020 New Drug Application (NDA) of oral BCV as a medical countermeasure for smallpox and the potential for associated non-dilutive capital,” stated Mike Sherman, Chief Executive Officer of Chimerix. “We are committed to pursuing programs where we can quickly address unmet patient needs with a meaningful benefit. Following an objective assessment of all internal activities, we will focus resources on the execution of the smallpox program as we identify additional attractive opportunities to create value for patients and shareholders. Our decisiveness here is a reflection of our determination to create value and help patients.

The decision to reduce staff following these strategic decisions was a difficult but necessary action. We are thankful for the commitment of these talented employees who have contributed so much to the Company. We will be working closely with those affected by the restructuring to support them in this transition,” added Mr. Sherman.

The Company plans to make the existing clinical supply of BCV available to patients as part of the expanded access program.

First Quarter and Recent Highlights

BCV for Smallpox
Today, Chimerix announced positive top-line results from the in-life portion of the ECTV study, which examined BCV using the Company’s second animal model of human smallpox conducted under the Animal Efficacy Rule. Chimerix is collaborating with the Biomedical Advanced Research and

Development Authority (BARDA) for the development of BCV as a potential medical countermeasure for smallpox.
The study was a randomized, blinded, placebo-controlled, parallel-group study to evaluate the efficacy of two different BCV dosing regimens versus a placebo (PBO) control group in mice infected with the mousepox virus. Mice were randomized to one of the following BCV treatment groups or placebo:
A BCV dose regimen of 20/5/5 mg/kg administered at 48-hour intervals with treatment initiation on post-infection days 4, 5, 6 or 7; or
A BCV dose regimen of 10/5/5 mg/kg administered at 48-hour intervals with treatment initiation on post-infection days 4, 5 or 6.

Day 5

Day 6
11 / 32 (34%)
4 / 32 (13%)

As shown above, all BCV treatment groups demonstrated a statistically significant survival benefit compared with placebo regardless of treatment initiation day. Survival was highest in both treatment groups where BCV was administered on Day 4, with the 20/5/5 mg/kg treatment regimen showing 84% survival and the 10/5/5 regimen showing 78% survival. Survival in the placebo group was 13%. The median time to death in animals receiving placebo was 8.5 days after infection, indicating that BCV treatment was effective at preventing mortality from mousepox virus even when treatment was initiated well past the midpoint of disease.

Data from this mousepox study and the Company’s rabbitpox studies are intended to address the requirement under the FDA’s Animal Efficacy Rule for two different animal models of efficacy. Further confirmatory analyses (e.g., secondary endpoints) of these studies are currently underway.

Contingent upon receiving final audited results of these two key animal efficacy studies, along with preparing data necessary to bridge to a recommended human dose, Chimerix intends to submit marketing applications for BCV for the treatment of smallpox in 2020.

Management and Corporate Updates

In April, Chimerix appointed Mike Sherman, former Chief Executive Officer of Endocyte, Inc., as Chief Executive Officer and Mike Andriole, former Chief Financial Officer of Endocyte, Inc., as the newly created Chief Business Officer. 

As a result of the restructuring described above, the Company will incur a restructuring related charge in the second quarter of 2019.

Revenues for the first quarter of 2019 increased to $2.4 million, compared to $0.8 million for the same period in 2018.

Research and development expenses decreased to $13.5 million for the first quarter of 2019, compared to $14.4 million for the same period in 2018.

Chimerix currently expects to end 2019 with approximately $140 million in capital to fund operations which will reflect payments related to the close-out of the oral and intravenous clinical trials and severance costs from the restructuring described above.
