ContraFect Reports Third Quarter 2019 Financial Results and

Provides Business Update

YONKERS, NY – November 12, 2019 — ContraFect Corporation (Nasdaq:CFRX), a clinical-stage biotechnology company focused on the discovery and development of direct lytic agents (DLAs), including lysins and amurin peptides, as new medical modalities for the treatment of life-threatening, antibiotic-resistant infections, today announced financial results for the third quarter ended September 30, 2019.

“The third quarter was marked by a successfulend-of-Phase 2 meeting with the FDA, and we are progressing towards our goal of initiating the Phase 3 trial of exebacase in patients withStaphylococcus aureus (Staph aureus) bacteremia, including right-sided endocarditis, by the end of this year,” said Roger J. Pomerantz, MD, President, Chief Executive Officer, and Chairman of ContraFect. “This is a very exciting time for the company as we continue to lead the way with the first direct lytic agent to potentially demonstrate superiority over current standard of care and usher in a new medical modality within the antibacterial space,” he continued.

Recent Corporate Highlights

• In October 2019, the Company announced it had completed anEnd-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) regarding the advancement of its lead lysin candidate, exebacase. At this meeting the Company obtained concurrence with the FDA on key design features of the Phase 3 protocol and that positive results from a single Phase 3 study could support a Biologics License Application (BLA) for approval of exebacase. Based on this feedback, the Company plans to initiate its Phase 3 DISRUPT trial (Direct Lysis ofStaph aureus Resistant Pathogen Trial) by the end of 2019. DISRUPT is a randomized, double-blind, placebo-controlled clinical study to assess the efficacy and safety of exebacase in approximately 350 patients withStaph aureus bacteremia, including right-sided endocarditis. Patients entering the Phase 3 study will be randomized 2:1 to either exebacase or placebo, with all patients receivingstandard-of-care antibiotics. The primary efficacy endpoint will be clinical response at Day 14 in patients with methicillin-resistantStaph aureus (MRSA) bacteremia, including right-sided endocarditis. Secondary endpoints will include clinical response at Day 14 in the AllStaph aureus bacteremia patient group (MRSA and methicillin-sensitiveStaph aureus (MSSA)),30-dayall-cause mortality in MRSA patients, and clinical response at later timepoints.

• In October 2019, the Company presented a Late-Breaker oral presentation on the reduction in health resource utilization among MRSA patients treated with exebacase from its recently completed Phase 2 study at ID Week 2019. Data showed that the median number of hospital days from study drug administration through discharge was 6 days in the exebacase-treated group compared to 10 days for patients who received standard of care (SOC) alone, while30-day all cause hospital readmission rates were 16% compared to 30.8% in the exebacase vs SOC antibiotics alone groups and 8.0% compared to 15.4% for those with confirmed S. aureus.

• In September 2019, the Company presented data from anex vivostudy of its amurin peptide candidate,Aap2-M1, at the jointly sponsored American Society of Microbiology and European Society of Clinical Microbiology and Infectious Disease (ASM/ESCMID) Conference on Drug Development to Meet the Challenge of Antimicrobial Resistance. Data demonstrated a clinically relevant concentration ofAap2-M1 eradicatedStenotrophomonas biofilms formed inside hemodialysis catheters removed from patients with suspected catheter-related bloodstream infections in the clinical care setting. These new data provided the first evidence of the activity of an amurin peptide against biofilm formed by a deadly Gram-negative pathogen in the setting of human infection.

Third Quarter 2019 Financial Results

• Research and development expenses were $5.3 million for the third quarter of 2019 compared to $5.7 million in the comparable period in 2018. This decrease was primarily attributable to a decrease in spending related to our Phase 2 clinical study of exebacase, as all related contract research services were completed in the current year period compared to the higher cost of active patient enrollment in the prior year period. This decrease was partially offset by an increase in manufacturing costs to support the advancement of exebacase into Phase 3 clinical development compared to the prior year period.

• General and administrative expenses were $2.4 million for the third quarter of 2019 compared to $2.1 million in the comparable period in 2018. This increase was due primarily to increases in costs incurred for legal and professional fees andnon-cash share-based compensation expense.

• Net loss was $5.4 million, or a loss of $0.07 per share, for the third quarter of 2019 compared to a net loss of $4.4 million, or a loss of $0.06 per share, for the comparable period in 2018. The increase in net loss was primarily due to a $0.01 share decrease in thenon-cash gain associated with the change in fair value of warrant liabilities.

• As of September 30, 2019, ContraFect had cash, cash equivalents and marketable securities of $10.5 million compared to $30.5 million at December 31, 2018.

About ContraFect

ContraFect is a biotechnology company focused on discovering and developing differentiated biologic therapies for life-threatening, drug-resistant infectious diseases, particularly those treated in hospital settings. An estimated 700,000 deaths worldwide each year are attributed to antimicrobial-resistant infections. We intend to address life threatening infections using our therapeutic product candidates from our platform of DLAs, which include lysins and amurin peptides. Lysins are a new class of DLAs which are recombinantly produced antimicrobial proteins with a novel mechanism of action associated with the rapid killing of target bacteria, eradication of biofilms and synergy with conventional antibiotics. Amurin peptides are a new class of DLAs, which exhibit broad-spectrum activity against a wide range of antibiotic-resistant Gram-negative pathogens, includingPseudomonas aeruginosa (P. aeruginosa),Acinetobacter baumannii, andEnterobacter species. We believe that the properties of our lysins and amurin peptides will make them suitable for targeting antibiotic-resistant organisms, such as methicillin-resistantStaph aureus (MRSA) andP. aeruginosa, which can cause serious infections such as bacteremia, pneumonia and osteomyelitis. We have completed a Phase 2 clinical trial for the treatment ofStaph aureus bacteremia, including endocarditis, with our lead lysin candidate, exebacase, which is the first lysin to enter clinical studies in the U.S.
