ContraFect Reports Fourth Quarter 2021 and Full Year 2021 Financial Results and Provides Business Update

Phase 3 DISRUPT study enrollment continues on course towards conducting interim futility analysis as anticipated in H1 2022

YONKERS, N.Y., March 24, 2022 (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, today announces business updates and financial results for the fourth quarter and full year ended December 31, 2021.

“Most importantly, we are on track and continue to expect to conduct the planned interim futility analysis based on approximately 60% of the MRSA study population by the end of the first half of 2022. Unlike other analyses for non-inferiority, this analysis will assess the probability for exebacase to achieve superiority on the primary efficacy endpoint over standard-of-care antibiotics alone,” said Roger J. Pomerantz, M.D., ContraFect’s President, Chief Executive Officer, and Chairman. “In addition, we look forward to the continued execution of our ongoing early and late stage preclinical pipeline programs for some of the most resistant bacterial pathogens, and to providing updates as they become available.”

Fourth Quarter 2021 Highlights and Recent Developments

• In January 2022, the Company received its second contract award from the Cystic Fibrosis Foundation. This contract award will support investigation of the potential utility of exebacase for treating serious lung infections caused by methicillin-resistant Staphylococcus aureus (MRSA) in people with cystic fibrosis (CF). The program, titled Nonclinical Assessment of Lysin Exebacase for Treating MRSA Infections in CF will, over the course of approximately 12 months, evaluate the in vitro activity of exebacase against bacterial specimens obtained from CF patients.
• In December 2021, a case study report was published in Clinical Infectious Diseases, a journal of the Infectious Disease Society of America (IDSA), highlighting the potential of exebacase to treat MRSA bacteremia in a pediatric population. The patient, a previously healthy 5-month-old male infant, presented to Duke University Hospital for evaluation of jerking movements and inability to sit independently. Following a full evaluation, it was determined that he had blood culture confirmed MRSA infection with life-threatening multi-organ involvement, affecting the brain (left temporal subdural empyema), upper airway (a retropharyngeal abscess), and heart (right-sided endocarditis). Despite targeted antibiotic therapy, optimized dosing, and attempts at source control, clearance of bacteremia and clinical improvement was not achieved with standard of care (SOC) antibiotics alone. The treating physician obtained authorization from the U.S. Food and Drug Administration (FDA) to use exebacase under an emergency individual patient investigational new drug application and the patient subsequently received one 3 mg dose of exebacase on hospital day 7. The patient continued to receive SOC anti-staphylococcal antibiotics throughout the hospital stay. Blood cultures became sterile on hospital day 12. The patient had ongoing clinical improvement and serial echocardiograms noted no evidence of heart valve vegetation on hospital day 40. The patient was discharged, without the need for additional surgery.
• In October 2021, the Company presented important new data at IDWeek 2021, in a late breaker, oral presentation, from the Phase 2 study of exebacase. These data demonstrated that exebacase, used in addition to standard-of-care antibiotics (SOCA), more rapidly resolved clinical symptoms of Staph aureus bacteremia versus SOCA alone. The median time to resolution was 3 days for exebacase-treated patients, as compared to 6 days for SOCA-alone patients. Notably, among the exebacase-treated patients with MRSA bacteremia, the median time to symptom resolution was 3 days, as compared to 7 days in patients who received SOCA alone. Additionally, 94.1% of exebacase-treated patients with MRSA bacteremia showed symptom resolution, compared with only 81.8% MRSA bacteremia patients treated with SOCA alone.
• In October 2021, new microbiologic surveillance data was presented at IDWeek 2021 on the in vitro activity of exebacase against Staph aureus clinical isolates causing bacteremia in the United States, including multidrug-resistant (MDR) strains. The data showed that Staph aureus accounted for approximately 25% of all pathogens recovered from blood specimens and nearly 40% of Staph aureus infected samples were of a methicillin-resistant phenotype. These data demonstrated the potent activity of exebacase and that its activity was consistent, regardless of resistance phenotype (MSSA, MRSA, including MDR isolates).
• In October 2021, the Company presented new data on the activity of DLAs against the most prevalent MDR pathogenic Gram-negative strains responsible for pulmonary infections in CF patients at the North American Cystic Fibrosis Conference. The data further support the in vitro activity profile of CF-370 and amurin AM1 against specific Gram-negative pathogens, including Pseudomonas aeruginosa (P. aeruginosa), Stenotrophomonas maltophilia, and Achromobacter spp.

Fourth Quarter 2021 Financial Results

• Research and development (R&D) expenses were $11.0 million for the fourth quarter of 2021 compared to $7.3 million in the comparable period in 2020. This increase was primarily attributable to increases in expenditures on contract research organizations (CROs) to support the active enrollment of patients in the Phase 3 DISRUPT study of exebacase, and on contract manufacturers to complete the process transfer of, and progress the validation of, the exebacase manufacturing process to support the chemistry, manufacturing and controls (CMC) activities required for potential BLA submission for exebacase. The manufacturing process for CF-370 has also moved forward towards enabling an Investigational New Drug (IND) application later this year. Finally, the Company increased its clinical development and CMC headcount and related personnel costs to support the continued advancement of its programs across the pipeline. These increases were partially offset by an increase in the reimbursement of expenses under the Company’s BARDA contract and grants compared to the prior year period.
• R&D expenses were $35.5 million for the year ended December 31, 2021, compared to $22.6 million for the year ended December 31, 2020. This increase was primarily attributable to increases in expenditures for the Phase 3 DISRUPT study of exebacase as we increased patient enrollment and expanded the number of clinical sites, for the manufacturing costs related to the process transfer, ongoing process validation and manufacturing of exebacase and for the expansion of the Company’s internal research, clinical development and CMC teams. These increases were partially offset by an increase in the reimbursement of expenses under the Company’s contract with BARDA and various grants compared to the prior year period.
• General and administrative (G&A) expenses were $3.0. million for the fourth quarter of 2021 compared to $3.4 million in the comparable period in 2020. This decrease was primarily attributable to decreases in legal expenses and recruiting costs.
• G&A expenses were $11.8 million for the year ended December 31, 2021, compared with $11.6 million for the year ended December 31, 2020. This increase was primarily attributable to the increase in insurance costs.
• Net loss was $4.4 million, or a loss of $(0.11) per share, for the fourth quarter of 2021 compared to net loss of $6.4 million, or a loss of $(0.23) per share, for the comparable period in 2020. The net loss in the current period includes a $9.7 million, or $0.25 per share, non-cash gain from the change in the fair value of the Company’s warrant liabilities. In the prior year period, the net loss included a $4.3 million, or $0.15 per share, non-cash gain from the change in the fair value of the Company’s warrant liabilities.
• Net loss was $20.3 million, or a loss of $(0.55) per share, for the year ended December 31, 2021 compared to net loss of $28.2 million, or a loss of $(1.24) per share, for the year ended December 31, 2020. The net loss for the current year period includes a $26.9 million, or $0.73 per share, non-cash gain from the change in the fair value of the Company’s warrant liabilities. In the prior year period, the net loss included an $8.1 million, or $0.35 per share, non-cash gain from the change in the fair value of the Company’s warrant liabilities. The net loss per share was also impacted by the year-over-year increase in the weighted average shares outstanding.
• As of December 31, 2021, ContraFect had cash, cash equivalents and marketable securities of $54.3 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 SOCA alone (74.1% for patients treated with exebacase compared to 31.3% for patients treated with SOCA 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 DISRUPT:

The Phase 3 DISRUPT study of exebacase is a randomized, double-blind, placebo-controlled clinical study conducted in the U.S. to assess the efficacy and safety of exebacase in approximately 350 patients with complicated Staph aureus bacteremia, including right-sided endocarditis. Patients enrolled in the Phase 3 study are randomized 2:1 to receive either exebacase or placebo, with all patients receiving SOCA. The primary efficacy endpoint of the study is clinical response at day 14 in patients with MRSA bacteremia, including right-sided endocarditis. Secondary endpoints include clinical response at day 14 in the All Staph aureus patients (MRSA and methicillin-sensitive Staph aureus (MSSA)), 30-day all-cause mortality in MRSA patients, and clinical response at later timepoints. An independent Data Safety Monitoring Board (DSMB) will conduct the interim futility analysis after 60% of the MRSA population (the primary endpoint study population) completes the Day 14 primary endpoint study visit.

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. However, based on the proprietary methods the Company has identified and utilizes to engineer lysins, CF-370 has exhibited the microbiologic attributes of the lysin class, including rapid and potent bactericidal activity, synergy with a broad range of SOCA 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.

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.
