What You Need to Know Before You Apply

What is the purpose of this trial?

Antibacterial prophylaxis is recommended in patients at high risk of infection, specifically patients undergoing acute leukemia induction therapy or hematopoietic stem cell transplant (HSCT) who are expected to have profound neutropenia (ANC\<100 neutrophils/milliliter) for more than seven days. Xerava™ (eravacycline) has a broad spectrum of activity including many multi-drug resistant strains of bacteria. It is not an agent used for treatment of febrile neutropenia, making eravacycline a very attractive alternative to consider in this prophylactic setting. Eravacycline has activity against MRSA, VRE, and Clostridioides difficile, all of which are common problems in this patient population. It also covers the majority of enteric gram-negative pathogens while also producing satisfactory tissue penetration and adequate plasma concentrations, which has classically been a concern with prior agents. Eravacycline has activity against coagulase-negative staphylococcus, which is a common catheter-related infection in leukemia and HSCT patients. The primary objective will be report the incidence of breakthrough infections during eravacycline prophylaxis for hematologic malignancy patients with prolonged neutropenia.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are taking strong inhibitors or inducers of cytochrome P450 3A4. Check Appendix B for a list of these medications.

How is the drug Eravacycline unique for blood cancer patients?

Eravacycline is unique because it is a newer antibiotic that can be used to prevent infections in blood cancer patients, particularly those who might be at risk for infections like vancomycin-resistant enterococci (VRE), which are difficult to treat with standard antibiotics. ^{1 2 3 4 5}

What Are the Treatments Tested in This Trial?

Interventions

• Eravacycline

Trial Overview The trial tests Xerava™ (eravacycline) as a preventive antibiotic in patients at high risk of infection due to prolonged neutropenia from leukemia treatment or stem cell transplant. The goal is to see if it can prevent infections better than current treatments.

How Is the Trial Designed?

Group I: Eravacycline Experimental Treatment 1 Intervention

Eravacycline- 1 mg/kg actual body weight IV Infusion over 60 minutes every 12 hours. Alternative dosing strategy 1.5mg/kg every 12 hourse.

Eravacycline is already approved in United States for the following indications:

Approved in United States as Xerava for:

• Complicated intra-abdominal infections

Published Research Related to This Trial

In a study involving 56 oncology patients with vancomycin-resistant enterococci (VRE) infections, the combination of quinopristin-dalfopristin and minocycline showed a response rate of 68%, indicating its effectiveness against these infections.

The treatment was associated with a notable side effect, with 36% of patients experiencing arthralgia or myalgia, highlighting the need to consider potential adverse effects when using this therapy.

Treatment of vancomycin-resistant enterococcal infections in the immunocompromised host: quinupristin-dalfopristin in combination with minocycline. Raad, I., Hachem, R., Hanna, H., et al.[2018]

In a study of 197 cancer patients, 13.4% developed bloodstream infections from vancomycin-resistant Enterococcus faecium (VRE), highlighting the serious risk of VRE infections in this population.

Key risk factors for developing VRE bloodstream infections included the use of vancomycin, diabetes, gastrointestinal procedures, and acute renal failure, suggesting that limiting vancomycin use and gastrointestinal interventions could help prevent these infections.

In a study of allogeneic hematopoietic cell transplantation patients, VRE bacteremia (VREB) was found to be infrequent, indicating a low incidence of this infection in the cohort.

Colonized patients were more likely to receive VRE-directed therapy compared to noncolonized patients, suggesting that screening for VRE may influence treatment decisions even in the absence of active infection.

Unintended Consequences of Pretransplant Vancomycin-Resistant Enterococcus Screening on Antimicrobial Stewardship Among Allogeneic Hematopoietic Cell Transplant Recipients. Stohs, EJ., MacAllister, T., Pergam, SA., et al.[2019]

In a study of 434 allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients, empiric therapy for vancomycin-resistant Enterococcus (VRE) bacteremia did not show a significant benefit compared to directed therapy, with similar clinical outcomes such as duration of bacteremia and mortality rates.

The findings suggest that empiric use of VRE-active agents in febrile, neutropenic patients who are VRE-colonized is not recommended, as it did not improve survival or reduce complications compared to targeted treatment.

Impact of Empiric Treatment for Vancomycin-Resistant Enterococcus in Colonized Patients Early after Allogeneic Hematopoietic Stem Cell Transplantation. Kamboj, M., Cohen, N., Huang, YT., et al.[2020]

In a study of 56 neutropenic cancer patients colonized with vancomycin-resistant enterococci (VRE), those with acute leukemia were significantly more likely to develop VRE bacteremia, with 100% of affected patients having acute leukemia compared to 56% of those without bacteremia.

C. difficile infection was identified as a major risk factor for developing VRE bacteremia, with a risk ratio of 8.2, highlighting the importance of monitoring for C. difficile in VRE-colonized patients, especially those with acute leukemia.
