ContraFect Announces First Patient Dosed in the Phase 1b/2 Study of Exebacase in Patients with Chronic Prosthetic Joint Infections of the Knee
YONKERS, N.Y., April 26, 2023 (GLOBE NEWSWIRE) -- 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 announces the first patient has been dosed in the Phase 1b/2 of exebacase in the setting of an arthroscopic debridement, antibiotics, irrigation, and retention (DAIR) procedure in patients with chronic prosthetic joint infections (PJI) of the knee due to Staphylococcus aureus (S. aureus) or Coagulase-Negative Staphylococci (CoNS).
“We are pleased by the rapid enrollment of the first patient in our PJI study of exebacase,” said Roger J. Pomerantz, MD, President, Chief Executive Officer, and Chairman of ContraFect. “It is important to understand that surgical revision of the infected prosthesis, the current standard of care for chronic PJI, has barely improved clinical outcomes over the past several decades. We believe exebacase has the potential to replace this debilitating and expensive surgical procedure, eradicate the infection, and significantly improve quality of life for patients with chronic PJIs suffering from pain and loss of mobility.”
The Phase 1b/2 study of exebacase is a randomized, double-blind, placebo-controlled clinical study conducted in France to assess the safety, pharmacokinetics (PK), and efficacy of intra-articularly administered exebacase in patients with chronic PJI of the knee due to S. aureus or CoNS. The study will be conducted in two parts. Part I will assess efficacy at an early, six-week timepoint in addition to safety and PK. Part II will be a long-term clinical safety and efficacy follow-up for a period of up to two years. Patients entering the study will be randomized 3:1 to either exebacase or placebo, with all patients receiving study drug in the setting of a DAIR Procedure.
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 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.

Examples of forward-looking statements in this release include, without limitation, statements regarding the Phase 1b/2 clinical study, patient dosing and patient enrollment, statements made by Dr. Pomerantz, whether exebacase has the potential to replace surgical revision, eradicate infection, and significantly improve quality of life for patients with chronic PJIs, ContraFect’s ability to discover and develop DLAs as new medical modalities for the treatment of life-threatening, antibiotic-resistant infections, whether ContraFect will address life-threatening infections using therapeutic candidates from 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. Because forward-looking statements relate to the future, they are subject to inherent risks, uncertainties and changes in circumstances that are difficult to predict and many of which are beyond ContraFect’s control, including, without limitation, that ContraFect has and expects to continue to incur significant losses, ContraFect’s need for additional funding, which may not be available, the occurrence of any adverse events related to the discovery, development and commercialization of ContraFect’s product candidates such as unfavorable clinical trial results, insufficient supplies of drug products, the lack of regulatory approval, or the unsuccessful attainment or maintenance of patent protection, changes in management may negatively affect ContraFect’s business and other important risks detailed under the caption “Risk Factors” in ContraFect's Annual Report on Form 10-K for the year ended December 31, 2022 and its other filings with the Securities and Exchange Commission.
