ContraFect Reports Fourth Quarter 2022 and Full Year 2022

Financial Results and Provides Business Update

YONKERS, New York – March 31, 2023 — 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 business updates and financial results for the fourth quarter and full year ended December 31, 2022.

“With the important support from our recent financings, we remain on track to both begin dosing patients in our Phase 1b/2 clinical study of intra-articular exebacase for the treatment of chronic prosthetic joint infections of the knee, and to file an IND for our second program, CF-370, for the treatment of Gram-negative infections, including resistant Pseudomonas, Acinetobacter and Klebsiella species,” said Roger J. Pomerantz, M.D., ContraFect’s President, Chief Executive Officer, and Chairman. “We are excited to get in the clinic with both of our lead programs, as we continue to execute on our mission to develop new therapies with the potential to significantly improve clinical outcomes for patients suffering from deadly and debilitating resistant bacterial infections.”

Fourth Quarter 2022 Highlights and Recent Developments

• In January 2023, the Company received ethics approval for the clinical study of intra-articularly administered exebacase in patients with chronic prosthetic joint infection (PJI) of the knee due to Staphylococcus aureus (S. aureus) or Coagulase-Negative Staphylococci (CoNS) from the Hôspices Civils de Lyon in Lyon, France, the clinical site where the study is being conducted. This approval followed the authorization of the Company’s Clinical Trial Application from ANSM, the French National Agency for the Safety of Medicines and Health Products in November 2022. This is a valuable opportunity for exebacase to demonstrate its potential to change standard of care and recapitulate the positive and durable clinical results we have observed in the compassionate use setting.

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 patients receiving study drug in the setting of a of a minimally-invasive arthroscopic debridement, antibiotics, irrigation, and retention (DAIR) Procedure.

• In December 2022, the Company closed on a $7.0 million registered direct offering and concurrent private placement of warrants to purchase common stock. In March 2023, the Company closed on another $10.0 million registered direct offering and concurrent private placement of warrants to purchase common stock, bringing the total estimated net proceeds of both capital raises to $15.3 million.

Fourth Quarter 2022 and Full Year 2022 Financial Results

• Research and development (R&D) expenses were $4.4 million for the fourth quarter of 2022 compared to $11.0 million in the comparable period in 2021. This decrease was primarily attributable to significantly reduced expenditures on the chemistry, manufacturing and controls (CMC) activities for exebacase, the contract research organizations (CROs) to support the continued closure of the Phase 3 DISRUPT study of exebacase and headcount and related personnel costs after the restructuring of the Company’s workforce in the third quarter of 2022.

• R&D expenses were $44.7 million for the year ended December 31, 2022, compared to $35.5 million for the year ended December 31, 2021. This increase was primarily attributable to the increase in spending on clinical activities related to the Phase 3 DISRUPT study of exebacase and on manufacturing costs for both exebacase and CF-370. These costs decreased significantly after we stopped enrollment in the Phase 3 DISRUPT study and implemented our restructuring plan.

• General and administrative (G&A) expenses were $2.3 million for the fourth quarter of 2022 compared to $3.0 million in the comparable period in 2021. This decrease was primarily attributable to decreases in headcount and related personnel costs after the restructuring of the Company’s workforce in the third quarter of 2022, legal expenses and professional fees.

• G&A expenses were $12.2 million for the year ended December 31, 2022, compared with $11.8 million for the year ended December 31, 2021. This increase was primarily attributable to an increase in legal expenses.

• Net loss was $9.8 million, or a loss of $16.14 per share, for the fourth quarter of 2022 compared to net loss of $4.4 million, or a loss of $8.95 per share, for the comparable period in 2021. The net loss in the current period includes $4.8 million, or $7.90 per share, of non-cash charges related to the value of the warrants issued in the Company’s December 2022 offering of securities and the allocation of the offering costs from the offering to the warrants. These charges were partially offset by a $1.7 million, or $2.72 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 $9.7 million, or $19.66 per share, non-cash gain from the change in the fair value of the Company’s warrant liabilities.

• Net loss was $65.2 million, or a loss of $124.97 per share, for the year ended December 31, 2022 compared to net loss of $20.3 million, or a loss of $44.12 per share, for the year ended December 31, 2021. The net loss for the current year period includes $4.8 million, or $9.23 per share, of non-cash charges related to the value of the warrants issued in the Company’s December 2022 offering of securities and the allocation of the offering costs from the offering to the warrants. These charges were partially offset by a $4.2 million, or $8.03 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 $26.9 million, or $58.46 per share, non-cash gain from the change in the fair value of the Company’s warrant liabilities.

• As of December 31, 2022, ContraFect had cash, cash equivalents and marketable securities of $13.7 million.

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 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.

Activities related to exebacase during the period of performance under the contract will be funded in part with federal funds from HHS; ASPR; BARDA, under contract number 75A501212C00021.
