ContraFect to Present New Late Breaking Phase 2 Exebacase Data on Rapid Symptom Resolution Among Patients with Staphylococcus aureus Bacteremia at IDWeek™ 2021

Data Being Presented Demonstrates Directly Positive Clinical Utility and Furthers the Understanding of Exebacase in Treating Staphylococcus aureus Bacteremia, Including Multidrug-Resistant MRSA

YONKERS, N.Y., Sept. 29, 2021 (GLOBE NEWSWIRE) -- ContraFect Corporation (Nasdaq:CFRX), a late 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, announces today that the Company has been selected to deliver a Late Breaker oral presentation on the rapid symptom resolution in adult patients with Staphylococcus aureus (Staph aureus) bacteremia who were treated with exebacase in the completed Phase 2 study.

The company will also present the results of a recently conducted microbiologic surveillance study of the activity of exebacase (CF-301) against Staph aureus specimens from patients with bacteremia in the United States, including multidrug-resistant Methicillin-resistant Staph aureus (MRSA) species.

These findings are all being presented at IDWeek^TM 2021, being held from September 29 through October 3, in San Diego, CA.

About Exebacase (CF-301):

Exebacase is a recombinantly-produced lysin (cell wall hydrolase enzyme) with potent bactericidal activity against Staph aureus, a major cause of bloodstream infections (BSIs) also known as bacteremia. In the Company’s Phase 2 study of exebacase, a pre-specified analysis of MRSA-infected patients showed that the clinical responder rate at Day 14 in patients treated with exebacase was nearly 43-percentage points higher than in patients treated with SOC antibiotics alone (74.1% for patients treated with exebacase compared to 31.3% for patients treated with SOC antibiotics alone (p=0.010)). In addition to the higher rate of clinical response, MRSA-infected patients treated with exebacase showed a 21-percentage point reduction in 30-day all-cause mortality (p=0.056), a four-day lower median length of hospital stay and meaningful reductions in hospital readmission rates. Exebacase is currently being studied in the Phase 3 DISRUPT superiority design study of exebacase in patients with Staph aureus bacteremia, including right-sided endocarditis.

Exebacase has the potential to be a first-in-class treatment for Staph aureus bacteremia. Exebacase was licensed from The Rockefeller University and is being developed at ContraFect.

About ContraFect

ContraFect is a biotechnology company focused on the discovery and development of DLAs, including lysins and amurin peptides, as new medical modalities for the treatment of life-threatening, antibiotic-resistant infections. 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 novel class of DLAs which exhibit broad-spectrum activity against a wide range of antibiotic-resistant Gram-negative pathogens, including P. aeruginosa, Acinetobacter baumannii, and Enterobacter species. We believe that the properties of our lysins and amurin peptides will make them suitable for targeting antibiotic-resistant organisms, such as MRSA and P. aeruginosa, which can cause serious infections such as bacteremia, pneumonia and osteomyelitis. We have completed a Phase 2 clinical trial for the treatment of Staph aureus bacteremia, including endocarditis, with our lead lysin candidate, exebacase, which is the first lysin to enter clinical studies in the U.S. Exebacase, currently being studied in a pivotal Phase 3 clinical study, was granted Breakthrough Therapy designation by the FDA for the treatment of MRSA bloodstream infections, including right-sided endocarditis, when used in addition to SOC anti-staphylococcal antibiotics.

Forward-Looking Statements

This press release contains, and our officers and representatives may make from time to time, “forward-looking statements” within the meaning of the U.S. federal securities laws.

Examples of forward-looking statements in this release include, without limitation, statements regarding: exebacase data and its clinical utility, the presentations, ContraFect’s ability to discover and develop DLAs as new medical modalities for the treatment of life-threatening, antibiotic-resistant infections, whether exebacase has the potential to be a first-in-class treatment for Staph aureus bacteremia, whether ContraFect will address life-threatening infections using its DLA platform, whether 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, whether amurins are a novel class of DLAs which exhibit broad-spectrum activity against a wide range of antibiotic-resistant Gram-negative pathogens, and whether the properties of ContraFect’s lysins and amurins will make them suitable for targeting antibiotic-resistant organisms, such as MRSA and P. aeruginosa. Forward-looking statements are statements that are not historical facts, nor assurances of future performance. Instead, they are based on ContraFect’s current beliefs, expectations and assumptions regarding the future of its business, future plans, strategies, projections, anticipated events and trends, the economy and other future conditions.
