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, today announced financial results and business updates for the first quarter ended March 31, 2022.

“I am very pleased to announce that we have eclipsed the enrollment threshold, meaning over 60% of the methicillin-resistant Staph aureus (MRSA) patients, needed for the interim futility analysis of our Phase 3 DISRUPT study to be conducted and we currently have about two-thirds of the entire study population enrolled as well. I want to thank our entire team for their hard work and tremendous persistence to achieve these milestones during the pandemic,” said Roger J. Pomerantz, M.D., ContraFect’s President, Chief Executive Officer, and Chairman. “Now we turn our attention to the interim futility analysis, which, unlike other analyses for non-inferiority endpoints, will enable the Data Safety Monitoring Board, or DSMB, to assess the probability for exebacase to achieve superiority on the primary efficacy endpoint of the study. Once the data necessary for this analysis is collected, processed and delivered to the DSMB, we will be informed of their recommendation regarding study continuation. We expect this to occur during the first week of July. We are extremely eager to get the recommendation of the DSMB, and, if positive, pivot with alacrity towards building our organization to support potential BLA submission, approval and commercialization of this new modality therapeutic.”

First Quarter 2022 Highlights and Recent Developments

• ContraFect expanded its senior team with the promotion of Matthew Salamone, SPHR, PHR to Vice President of Human Resources who will support the anticipated growth and development of the Company through the upcoming key milestones.
• In April 2022, the Company provided an oral presentation at the 32^nd European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) Annual Meeting of new data from an in vivo efficacy study of CF-370 in a rabbit acute pneumonia model caused by an extensively drug-resistant (XDR) Pseudomonas aeruginosa (P. aeruginosa). Multiple dose regimens of CF-370 administered alone and in addition to amikacin, demonstrated statistically significant reductions of bacteria counts in the lungs as compared to amikacin alone and vehicle controls. Statistically significant reductions of bacteria counts in secondary organs of interest, the spleen and the kidney, were also seen when CF-370 was administered in addition to amikacin compared to the administration of amikacin alone.
• In April 2022, ContraFect presented multiple posters at the 32^nd ECCMID Annual Meeting characterizing the susceptibility profile of CF-370. Utilizing the standard 28-day serial passage method to induce in vitro resistance, CF-370 demonstrated an extremely low propensity for developing decreased susceptibility to the Gram-negative ESKAPE pathogens (P. aeruginosa, Acinetobacter baumannii, Klebsiella pneumoniae and Enterobacter cloacae) as well as other deadly Gram-negative pathogens – Escherichia Coli, Stenotrophomonas maltophilia, and Achromobacter xylosoxidans. Furthermore, CF-370 also demonstrated the ability to suppress in vitro resistance of P. aeruginosa to current standard of care antibiotics – meropenem, tobramycin and levofloxacin.
• In January 2022, the Company received its second contract award from the Cystic Fibrosis Foundation. This contract award will support in vitro and in vivo investigations of the potential utility of exebacase for treating cystic fibrosis (CF) lung infections caused by MRSA. The program will expand and augment the positive data from the in vitro characterization of the activity of CF-370 and selected amurin peptides against bacterial specimens obtained from CF patients under the first award.

First Quarter 2022 Financial Results

• Research and development expense was $12.7 million for the first quarter of 2022 compared to $8.0 million in the comparable period in 2021. This increase was primarily attributable to an increase in spending on manufacturing costs related to the process transfer, analytical and process validation, and manufacturing of exebacase that will support a potential BLA submission and on clinical activities as we continued to enroll patients and expand the number of clinical sites in the Phase 3 DISRUPT study of exebacase. These increases were partially offset by a decrease in spending on non-clinical studies of CF-370 and our other preclinical programs.
  
  
• General and administrative expense was $3.3 million for the first quarter of 2022 compared to $2.8 million in the comparable period in 2021. This was due primarily to an increase in costs for personnel and related expenses.
  
  
• Net loss was $20.2 million, or a loss of $(0.51) per share, for the first quarter of 2022 compared to a net loss of $5.2 million, or a loss of of $(0.18) per share, for the comparable period in 2021. The net loss per share in the current period includes a $4.2 million, or $0.11 per share, non-cash charge from the change in the fair value of the Company’s warrant liabilities. In the prior year period, the net loss per share included a $5.6 million, or $0.19 per share, non-cash gain from the change in the fair value of the Company’s warrant liabilities.
  
  
• As of March 31, 2022, ContraFect had cash, cash equivalents and marketable securities of $42.3 million.

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 was well-tolerated and treatment emergent adverse events, including serious treatment-emergent serious adverse events (SAEs) were balanced between the treatment groups. There were no SAEs determined to be related to exebacase, there were no reports of hypersensitivity related to exebacase and no patients discontinued treatment with study drug in either treatment group.

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. The lysin was licensed from The Rockefeller University and is being developed at ContraFect.

About CF-370:

CF-370 is an investigational first-in-class therapeutic candidate targeting P. aeruginosa, a Gram-negative pathogen. CF-370 has been engineered to bypass the outer membrane of the bacteria and to enable potent activity in human serum. The Company believes this is a significant milestone for direct lytic agents as native lysins are typically unable to penetrate the outer membrane of Gram-negative bacteria and consequently unable to work in vitro in human blood or in animal models. However, based on the proprietary methods the Company has identified and utilizes to engineer lysins, CF-370 has exhibited the hallmark in vitro microbiologic attributes of the lysin class, including rapid and potent bactericidal activity, synergy with a broad range of standard of care agents and the eradication of biofilms in preclinical studies. The promising data from animal models support the potential therapeutic utility of CF-370 for the treatment of serious infections caused by P. aeruginosa, including hospital-acquired and ventilator-associated pneumonias and pulmonary exacerbations of cystic fibrosis.

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 highly resistant strains of 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 development as a treatment of MRSA bloodstream infections, including right-sided endocarditis, when used in addition to SOC anti-staphylococcal antibiotics.
