FETROJA® (cefiderocol) Approved by TFDA in Taiwan

OSAKA, Japan, February 22, 2024 - Shionogi & Co., Ltd. (Head Office: Osaka, Japan; Chief Executive Officer: Isao Teshirogi, Ph.D.; hereafter "Shionogi") announced that Taiwan Shionogi & Co., Ltd., a subsidiary of Shionogi, has received approval from the Taiwan Food and Drug Administration (TFDA) for FETROJA(cefiderocol) in the treatment of complicated urinary tract infections, including pyelonephritis, and hospital-acquired pneumonia (including hospital-acquired bacterial pneumonia and ventilator-acquired associated bacterial pneumonia) caused by susceptible Gram-negative microorganisms. This approval applies to adult patients.


FETROJA is a siderophore cephalosporin antibiotic developed by Shionogi, and new drug application in Taiwan was filed on December 13, 2022.1 FETROJA exerts its antimicrobial activity by effectively penetrating the outer membrane of gram-negative bacteria, including multidrug-resistant bacteria, through the utilization of the bacteria's iron transport system. FETROJA has been approved in Japan, Europe, and the United States and is currently being marketed in more than 10 countries and regions2,3,4  and is expected to provide a new treatment option for Taiwanese patients suffering from infections caused by drug-resistant bacteria.


Shionogi has identified protecting people from the threat of infectious diseases as a material issue, and is working towards achieving comprehensive care for infectious diseases. As part of this commitment, we are working with The Global Antibiotic Research and Development Partnership (GARDP) and the Clinton Health Access Initiative (CHAI) to provide access to cefiderocol, with proper stewardship, in a wide range of low- and upper-middle-income countries.5

About FETROJA (cefiderocol)

Cefiderocol for injection is the first and only siderophore cephalosporin antibiotic for the treatment of serious Gram-negative infections. It has 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, cefiderocol 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 cefiderocol 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. Cefiderocol has already obtained approval in both Europe and United States, and is sold under the product name FETCROJA in Europe and FETROJA in the United States. It is listed on the World Health Organization's Essential Medicines List.


About AMR

Antimicrobial resistance (AMR) is a major health burden which urgently needs to be addressed.6 Globally, in 2019, there were 1.27 million deaths attributable to bacterial AMR.7 Infections caused by carbapenem-resistant Gram-negative bacteria are often associated with a high mortality rate. 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.8
