This clinical trial is focused on patients with acute leukemia or those who have undergone an allogeneic hematopoietic stem cell transplant. These patients are at risk of developing a condition called febrile neutropenia, which is a fever that occurs when the body has a low number of a type of white blood cell called neutrophils. This condition can be particularly dangerous if the patients are also colonized by certain bacteria, such as carbapenem-resistant Enterobacteriaceae or Pseudomonas aeruginosa, which are resistant to many antibiotics.
The study is testing a treatment called Pentaglobin, which is a solution containing different types of proteins called immunoglobulins. These proteins are part of the immune system and help the body fight infections. The purpose of the study is to see if adding Pentaglobin early in the treatment can reduce the risk of death and improve survival rates in these patients. The study will compare the effects of Pentaglobin with the best available antimicrobial therapy, which is the standard treatment for infections.
Participants in the study will receive Pentaglobin through an infusion, which means it will be given directly into the bloodstream. The treatment will be administered for a maximum of three days. The study will monitor the patients for several months to see how well they respond to the treatment and to check for any side effects. The goal is to find out if Pentaglobin can help improve the outcomes for patients with febrile neutropenia who are at high risk due to these resistant bacteria.
