Paediatric US Cancer Patient with Recalcitrant Blood and Liver Infection Successfully Treated with Zaynich™

A 15-year-old US patient with Acute Myeloid Leukemia (AML), a type of blood and bone marrow cancer, has been successfully cured of a severe, drug-resistant infection following treatment with Zaynich™ (Zidebactam/Cefepime, WCK 5222) under compassionate use. The patient, who had not responded to nine antibiotics across five different classes over a span of 45 days, was left with few treatment options before Zaynich™ was administered.

This case, treated at St. Jude's Hospital in Memphis, USA, involved a severely immunocompromised patient due to chemotherapy. The infection was traced to abscesses in the liver, which led to recurrent bloodstream infections caused by E. coli producing NDM, a highly resistant variant of metallo-β-lactamase (MBL). Despite the use of multiple antibiotics, including Tigecycline, Plazomicin, Levofloxacin, Cefepime, Gentamicin, Eravacycline, Polymyxin B, and Ceftazidime/avibactam + Aztreonam, the infection persisted.

Given the patient's critical condition, the medical team sought approval from the US FDA for the compassionate use of Zaynich™. Following the approval, the patient was treated with Zaynich™ for 41 days, resulting in the successful resolution of the infection and a stabilization of the patient's clinical condition. This marks the third US patient to benefit from Zaynich™ which is attributable to its unique β-lactam enhancer mechanism.

To date, 51 patients with life-threatening Gram-negative infections have been treated successfully under the compassionate use of Zidebactam/Cefepime, demonstrating its potential in combating drug-resistant infections.
