ContraFect Reports Third Quarter 2020 Financial Results and Provides Business Update

CARB-X and Cystic Fibrosis Foundation grants provide significant additional funding to advance CF-370 for Pseudomonas aeruginosa infections

Initiated expanded access program with exebacase for the treatment of persistent MRSA bloodstream infections in COVID-19 patients

YONKERS, New York — November 13, 2020 — 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 and business updates for the third quarter ended September 30, 2020.

“We are pleased with the progress of the Phase 3 DISRUPT superiority study of exebacase, which received Breakthrough Therapy designation from the FDA earlier this year, in patients suffering from life-threatening Staph aureus bloodstream infections,” said Roger J. Pomerantz, M.D., President, Chief Executive Officer, and Chairman of ContraFect. “We also continue to advance our pipeline programs towards the clinic and appreciate the tremendous financial support from CARB-X and the Cystic Fibrosis Foundation for our second product candidate, CF-370, an engineered lysin targeting Pseudomonas aeruginosa.”

Q3 2020 Highlights and Recent Developments

• In October, ContraFect initiated an expanded access program to provide exebacase for the treatment of persistent bacteremia caused by methicillin-resistant Staphylococcus aureus (MRSA) in COVID-19 patients. The Company is providing expanded access to exebacase under a treatment protocol available to clinical sites participating in the ongoing Phase 3 study, which enables physicians to use exebacase to treat severely ill COVID-19 patients with persistent MRSA bacteremia, despite treatment with standard of care antibiotics. Hospitalized patients with COVID-19 may now have access to exebacase since they are not eligible to participate in the ongoing Phase 3 study.

• In August, the Company entered into an agreement with the Cystic Fibrosis Foundation to investigate the potential utility of DLAs against resistant Gram-negative pathogens which afflict Cystic Fibrosis (CF) patients. The first stage of the agreement will provide funding for the in vitro characterization of the activity of CF-370, an engineered lysin targeting Pseudomonas aeruginosa, and selected amurin peptides, against bacterial specimens obtained from CF patients at different stages of disease. With supportive data, ContraFect plans to evaluate future clinical development of CF-370 and/or amurin peptides as potential therapeutics for the treatment of pulmonary exacerbations in CF patients.

• In July, the Company announced that CARB-X (Combating Antibiotic Resistant Bacteria Biopharmaceutical Accelerator), a global non-profit partnership dedicated to accelerating antibacterial research and development, awarded the Company up to $18.9 million in additional non-dilutive capital to progress CF-370 through IND-enabling activities toward Phase 1 clinical trials. The award provides initial funding of $4.9 million, and ContraFect could receive additional funding at the discretion of CARB-X if certain project milestones are met.

Ongoing COVID-19 Response

• The Phase 3 DISRUPT (Direct Lysis of Staph aureus Resistant Pathogen Trial) study of exebacase is ongoing. The Company continues to enroll patients and open new clinical trial sites across the United States. The study continues to experience some delays in patient enrollment due to the diversion of healthcare resources resulting from the COVID-19 pandemic in certain high impact areas.

Third Quarter 2020 Financial Results

• Research and development (R&D) expenses were $4.7 million for the third quarter of 2020 compared to $5.3 million in the comparable period in 2019. This decrease was primarily attributable to a decrease in internal and external research costs and a decrease in chemistry, manufacturing and controls (CMC) activities in the current quarter. These decreases were partially offset by increases in CRO expenses, clinical headcount and related personnel costs and professional fees to support the ongoing Phase 3 clinical study of exebacase.

• General and administrative (G&A) expenses were $2.6 million for the third quarter of 2020 compared to $2.4 million in the comparable period in 2019. This increase was primarily attributable to increases in professional fees and insurance costs.

• GAAP net income was $3.4 million, or $0.12 per share, for the third quarter of 2020 compared to a GAAP net loss of $5.4 million, or $0.67 per share, for the comparable period in 2019. After adjustment for the dilutive impact of the change in fair value of certain warrant liabilities, the Company reported a net loss of $5.4 million, or $0.19 per diluted share, for the third quarter of 2020.

• As of September 30, 2020, ContraFect had cash, cash equivalents and marketable securities of $50.2 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 on top of standard-of-care (SOC) antibiotics was nearly 43-percentage points higher than in patients treated with SOC antibiotics alone (74.1% for patients treated with exebacase and SOC antibiotics, 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 mean length of hospital stay and meaningful reductions in 30-day 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 SOC antibiotics. 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. The company plans to conduct an interim futility analysis following the enrollment of approximately 60% of the study population.

About ContraFect:

ContraFect is a 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. 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 Pseudomonas aeruginosa (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 in adult patients.
