OSAKA, Japan and FLORHAM PARK, N.J., JULY 8, 2021 – Shionogi & Co., Ltd. (Head Office: Osaka, Japan; President & CEO: Isao Teshirogi, Ph.D.) (hereafter “Shionogi”) today announces key data for FETROJA® (cefiderocol), a novel siderophore cephalosporin, presented at the virtual European Congress of Clinical Microbiology and Infectious Diseases (ECCMID), July 9-12, 2021.
FETROJA has extensive in vitro activity against some of the most difficult to treat carbapenem-resistant Gram-negative bacteria
The susceptibility profiles of FETROJA and comparators were evaluated against a European and U.S. collection of Gram-negative bacteria as part of the SENTRY Antimicrobial Surveillance Program. In these studies, the in vitro activity of FETROJA was evaluated against non-fermenters such as P. aeruginosa, A. baumannii-calcoaceticus complex, and S. maltophilia, as well as Enterobacterales isolates, including carbapenem-resistant strains. FETROJA also demonstrated broad activity against the isolates resistant to recently approved beta-lactam / beta-lactamase inhibitor combinations. For the resistant phenotypes, FETROJA was the most active agent tested. In vitro activity does not necessarily correlate with clinical efficacy.1,2,3,4
“These data from the SENTRY studies are very encouraging as they show that cefiderocol is broadly active against Enterobacterales and non-fermenters like Pseudomonas, Acinetobacter and Stenotrophomonas, including carbapenem-resistant strains, performing better than all other comparators tested. Infections caused by multi-drug resistant Pseudomonas are inherently difficult to treat as many antibiotics are not effective against this critical pathogen,” commented Dr. Dee Shortridge, Senior Director for Antimicrobial Development at JMI Laboratories. “Increasing resistance in Gram-negative bacteria is a real issue, especially where it compromises carbapenems.”
Real-world data for early use of FETROJA are presented, including in those co-infected with COVID-19
An overview of susceptibility and clinical outcomes for isolates from 141 patients who received FETROJA in a global compassionate use program reported that clinical response was positive overall in patients receiving FETROJA to treat Gram-negative infections caused by pathogens resistant to all alternative antibiotics, or where unacceptable toxicity of alternative antibiotics had been documented. The most frequent pathogens were P. aeruginosa (50%) and A. baumannii complex (24%).5
Initial data from the FETROJA Early Access Program for patients with no appropriate therapeutic alternative for resistant Gram-negative infections have also been presented. Of the 237 patients treated with FETROJA, 37.1% (n=88) were also co-infected with COVID-19. Carbapenem-resistant A. baumannii (n=96; 40.5%) and carbapenem-resistant P. aeruginosa (n=78; 32.9%) were the most common pathogens. The most common infections were pneumonia (n=106; 44.7%) and BSI/sepsis (n=93; 39.2%). The high level of requests for FETROJA between April 1 and December 31, 2020 demonstrate the continued high unmet need for new antimicrobials, especially for pathogens associated with high rates of resistance such as carbapenem-resistant A. baumannii and carbapenem-resistant P. aeruginosa.
“Shionogi is excited to share these real-world data at ECCMID, providing initial evidence that FETROJA is addressing the high unmet need for new antimicrobials effective against important resistant pathogens, such as carbapenem-resistant Acinetobacter or Pseudomonas,” commented Dr. Mark Hill, Global Head of Market Access, Shionogi. “Antimicrobial resistance is a major health burden responsible for approximately 700,000 deaths globally every year, and it is of critical importance that we continue to develop effective new treatments to tackle this growing threat.”
Epidemiology studies highlight the prevalence of carbapenem-resistant Gram-negative isolates which are associated with high mortality and unmet need
A retrospective chart review carried out at sites across the UK, France and Spain–the CARBAR study–identified that over 8% of Gram-negative isolates were carbapenem-resistant. Pneumonia was the most prevalent infection caused by carbapenem-resistant Gram-negative isolates (40.7%). The most frequent pathogen identified in these patients was carbapenem-resistant P. aeruginosa (37%) followed by Enterobacterales (36%). 59% of patients required mechanical ventilation and the mortality rate was 44% across all pathogens, indicating a high unmet need, significant healthcare utilization and limited treatment options in this patient population.7,8,9
Antimicrobial resistance (AMR)
Antimicrobial resistance (AMR) is a major health burden that urgently needs to be addressed. Globally, approximately 700,000 people die as a result of infections caused by resistant pathogens every year.10 Infections caused by carbapenem-resistant Gram-negative bacteria are often associated with a high mortality rate.11 If no action is taken, antimicrobial resistance is predicted to kill 10 million people every year by 2050, at a cumulative cost to global economic output of 100 trillion USD.10
About FETROJA® (cefiderocol) for Injection
FETROJA® (cefiderocol) is a cephalosporin antibiotic with a novel mechanism for penetrating the outer cell membrane of Gram-negative pathogens by acting as a siderophore. In addition to entering cells by passive diffusion through porin channels, FETROJA binds to ferric iron and is actively transported into bacterial cells through the outer membrane via the bacterial iron transporters, which function to incorporate this essential nutrient for bacteria. These mechanisms allow FETROJA to achieve high concentrations in the periplasmic space where it can bind to penicillin-binding proteins and inhibit cell wall synthesis in the bacterial cells. FETROJA has also demonstrated in vitro activity against certain bacteria that contain very problematic resistant enzymes such as ESBLs, AmpC, serine- and metallo-carbapenemases. Data from multinational surveillance studies for FETROJA demonstrated potent in vitro activity against a wide spectrum of Gram-negative pathogens including carbapenem-resistant A. baumannii, P. aeruginosa, Enterobacterales, and S. maltophilia. The clinical significance of the in vitro data is unknown. FETROJA has poor in vitro activity against Gram-positive or anaerobic bacteria.
Cefiderocol, under the brand name FETCROJA®, is approved by the European Commission for the treatment of infections due to aerobic Gram-negative bacteria in adults 18 years or older with limited treatment options.
Fetroja® (cefiderocol) is indicated in patients 18 years of age or older for the treatment of complicated urinary tract infections (cUTIs), including pyelonephritis caused by the following susceptible Gram-negative microorganisms: Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa, and Enterobacter cloacae complex.
Fetroja is indicated in patients 18 years of age or older for the treatment of hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia, caused by the following susceptible Gram-negative microorganisms: Acinetobacter baumannii complex, Escherichia coli, Enterobacter cloacae complex, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Serratia marcescens.
To reduce the development of drug-resistant bacteria and maintain the effectiveness of Fetroja and other antibacterial drugs, Fetroja should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria.
SELECT IMPORTANT SAFETY INFORMATION
Fetroja is contraindicated in patients with a known history of severe hypersensitivity to cefiderocol or other beta-lactam antibacterial drugs, or any other component of Fetroja.
WARNINGS AND PRECAUTIONS
Increase in All-Cause Mortality in Patients with Carbapenem-Resistant Gram-Negative Bacterial Infections
An increase in all-cause mortality was observed in patients treated with Fetroja as compared to best available therapy (BAT) in a multinational, randomized, open-label trial in critically ill patients with carbapenem-resistant Gram-negative bacterial infections (NCT02714595). Patients with nosocomial pneumonia, bloodstream infections, sepsis, or cUTI were included in the trial. BAT regimens varied according to local practices and consisted of 1 to 3 antibacterial drugs with activity against Gram-negative bacteria. Most of the BAT regimens contained colistin.
The increase in all-cause mortality occurred in patients treated for nosocomial pneumonia, bloodstream infections, or sepsis. The 28-Day all-cause mortality was higher in patients treated with Fetroja than in patients treated with BAT [25/101 (24.8%) vs 9/49 (18.4%), treatment difference 6.4%, 95% CI (-8.6, 19.2)]. All-cause mortality remained higher in patients treated with Fetroja than in patients treated with BAT through Day 49 [34/101 (33.7%) vs 10/49 (20.4%), treatment difference 13.3%, 95% CI (-2.5, 26.9)]. Generally, deaths were in patients with infections caused by Gram-negative organisms, including non-fermenters such as Acinetobacter baumannii complex, Stenotrophomonas maltophilia, and Pseudomonas aeruginosa, and were the result of worsening or complications of infection, or underlying comorbidities. The cause of the increase in mortality has not been established.
Closely monitor the clinical response to therapy in patients with cUTI and HABP/VABP.
