Chimerix Reports Fourth Quarter and Year End 2023 Financial Results and Provides Operational Update

– ONC201 ACTION Study Progressing; Reiterate Interim OS Data Expected in 2025, Final OS Data Expected in 2026 –

– Phase 2 ONC201 Data Published in Peer-Reviewed Journal of Clinical Oncology –

– $204 Million in Cash and Equivalents at December 31, 2023 –

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

DURHAM, N.C., February 29, 2024 (GLOBE NEWSWIRE) -- Chimerix (NASDAQ:CMRX), a biopharmaceutical company whose mission it is to develop medicines that meaningfully improve and extend the lives of patients facing deadly diseases, today reported financial results for the fourth quarter and full-year ended December 31, 2023 and provided an operational update.

“Following strong clinical development in 2023, we remain very focused on advancing the ONC201 ACTION study, completing ONC206 dose escalation this year and strengthening our executive team as we prepare for potential commercialization of ONC201” said Mike Andriole, Chief Executive Officer of Chimerix. “We are making good progress enrolling our global Phase 3 ACTION study and are excited about the prospect of having interim overall survival data next year. In addition, we are pleased to share that the ONC201 Phase 2 data was recently published in the Journal of Clinical Oncology which further elucidates key characteristics of response and detailed patient-level data.”

“During the fourth quarter, we were delighted to strengthen our Board of Directors with the addition of Lisa Decker, Ph.D., as well as strengthen the management team with the promotion of Michelle LaSpaluto to Chief Financial Officer and the additions of Tom Riga as Chief Operating and Commercial Officer and Pablo Lee, MD, as Vice President of Medical Affairs. We are confident their collective expertise will be invaluable assets to Chimerix as we seek to maximize our future growth potential for patients and shareholders,” added Mr. Andriole.

ONC201

Journal of Clinical Oncology Publication

In February 2024, “ONC201 (dordaviprone) in Recurrent H3 K27M-mutant Diffuse Midline Glioma,” was published in the Journal of Clinical Oncology (JCO), a peer reviewed journal of the American Society of Clinical Oncology (ASCO). The manuscript reports in detail the results of 50 patients with recurrent H3 K27M-DMG treated with monotherapy ONC201 who were evaluable for objective response by Response Assessment in Neuro-Oncology (RANO) high grade glioma (HGG) criteria. ONC201 demonstrated a median overall survival (mOS) of 13.7 months (95% CI: 8.0 - 20.3), with an overall two-year rate of survival of 35% (95% CI: 21-49) from the start of ONC201 treatment post-recurrence. Chimerix previously conducted a natural disease history study (n=43) in the recurrent setting evaluating patients who did not receive ONC201 which showed a mOS of 5.1 months (95% CI: 3.9 - 7.7) with an overall two-year survival rate of 11% (95% CI 3.3-24.2). The top-line data from this JCO publication were previously disclosed by Chimerix. The journal can be accessed at https://ascopubs.org/doi/10.1200/jco.23.01134.

The Phase 3 ACTION trial is currently enrolling patients at over 130 sites in 13 countries. The trial enrolls patients shortly after completion of front-line radiation therapy that is the standard of care. The study is designed to enroll 450 patients randomized 1:1:1 to receive ONC201 at one of two dosing frequencies or


placebo. Participants are randomized to receive 625mg of ONC201 once per week (the Phase 2 dosing regimen), 625mg twice per week on two consecutive days or placebo. The dose will be scaled by body weight for patients <52.5kg. For more information, please visit clinicaltrials.gov.

ONC206

ONC206 is a second generation ClpP agonist and DRD2 antagonist that has demonstrated monotherapy anti-cancer activity in pre-clinical models in primary CNS tumors and solid tumors outside of the CNS. Phase I dose escalation trials continue at the National Institutes of Health (NIH) and the Pacific Pediatric Neuro-Oncology Consortium (PNOC) in adult and pediatric CNS tumor patients, respectively. To date, ONC206 has been generally well tolerated with no dose limiting toxicities. The dose escalation trials are currently dosing at more frequent dose schedules, which are expected to increase the duration of therapeutic exposure. Chimerix expects to report preliminary safety and pharmacokinetic data from these trials beginning in mid-2024.

Fourth Quarter 2023 Financial Results

Chimerix's balance sheet at December 31, 2023 included $204.5 million of capital available to fund operations, no debt, and approximately 88.9 million outstanding shares of common stock.

Chimerix reported a net loss of $18.2 million, or $0.20 per basic and diluted share, for the fourth quarter of 2023, compared to a net loss of $21.0 million, or $0.24 per basic and diluted share for the fourth quarter of 2022. 

Research and development expenses decreased to $15.6 million for the three-month period ended December 31, 2023, compared to $19.3 million for the same period in 2022. This decrease was primarily driven by one-time costs associated with a reduction in force related to the TEMBEXA divestiture in the comparable 2022 period.

General and administrative expenses decreased to $5.2 million for the fourth quarter of 2023, compared to $5.3 million for the same period in 2022. 

Full Year 2023 Financial Results

Chimerix reported a net loss of $82.1 million, or $0.93 per basic and diluted share, for the year ended December 31, 2023. For the year ended December 31, 2022, Chimerix recorded net income of $172.2 million, or $1.97 per basic and $1.94 per diluted share. The decrease was primarily driven by the gain on sale of TEMBEXA to Emergent BioSolutions in 2022.

Revenues for 2023 decreased to $0.3 million, compared to $33.8 million in 2022. The decrease was primarily related to deliveries under international TEMBEXA procurement agreements in the comparable 2022 period.

Research and development expenses decreased to $68.8 million for the year ended December 31, 2023, compared to $71.6 million for the year ended December 31, 2022.

General and administrative expenses increased to $24.6 million for the year ended December 31, 2023, compared to $22.1 million for the year ended December 31, 2022. 

Conference Call and Webcast

Chimerix will host a conference call and live audio webcast to discuss fourth quarter and full-year 2023 financial results and provide a business update today at 8:30 a.m. ET. To access the live conference call, please dial 646-307-1963 (domestic) or 800-715-9871 (international) at least five minutes prior to the start time and refer to conference ID 6933453.

16 • No approved therapies for H3 K27M mutant glioma, ONC201 is the leading program targeting this mutation globally • Potential market opportunity ~$750 million • Approximately 5,000 patients in top seven markets1 • Ultra-orphan indication drug pricing • H3 K27M mutations most often in children / young adults • Low barriers to adoption - No effective alternative therapies - High unaided awareness among neuro-oncologists - Mutation routinely identified by existing diagnostics - Longer-term, potentially combinable with other glioma therapies • Patent protection for lead indication into 2037 - potential U.S. patent term extension (up to five years) H3 K27M-mutant glioma: rapid ramp to peak revenue expected 1. By extrapolation of the estimated US incidence rate to the top seven markets

 
17 Potential for ONC201 beyond brain tumors • Single agent responses in Ph 2 neuroendocrine trial of ONC201 observed in subset (PCPG) • PCPG are adrenal-related tumors with elevated DRD2 expression • Five patients have been treated > 1 year • Fewer short-term and potential long-term toxicities than other paraganglioma therapies ONC201 efficacy results in dopamine-secreting tumors outside the brain Ph 2 Study of ONC201 in Neuroendocrine Tumors in investigator- reported data from clinical trial NCT # (NT03034200) 1. https://aacrjournals.org/clincancerres/article/28/9/1773/694456/Phase-II-Study-of-ONC201-in-Neuroendocrine-Tumors

 
ONC201 Mechanism of Action

 
19 • ONC201 can selectively induce apoptosis in cancer cells by altering the activity of two protein targets • DRD2 antagonism - DRD2 is a G protein-coupled neuroreceptor that regulates Ras signaling - ONC201 antagonizes DRD2, inhibiting Ras signaling pathways • ClpP agonism - ClpP normally degrades misfolded proteins in mitochondria - ONC201 modifies ClpP conformation, promoting excess degradation of specific mitochondrial proteins important for cancer cell viability ONC201 directly engages DRD2 and ClpP ONC201 upregulates integrated stress response, inactivates Akt/ERK, and selectively induces tumor cell death ClpP=caseinolytic protease P; OXPHOS=oxidative phosphorylation; DRD2=Dopamine receptor D2; ATF4=activating transcription factor 4; CHOP=C/EBP-homologous protein; ERK=extracellular-regulated kinase;
