What is this trial about?

A plain-language summary of the goals, design and what participants do

This study focuses on treating chemotherapy-induced fever in adult patients with hematological disorders such as lymphoma, myelodysplasia, and acute myeloblastic leukemia. The purpose is to compare two different antibiotic treatments in patients who develop fever after receiving chemotherapy. The treatments being studied are amoxicillin-clavulanate alone versus a combination of amoxicillin-clavulanate with ciprofloxacin.

The study examines how well these antibiotic treatments work in patients who can receive care outside the hospital. The medications are taken by mouth, and the treatment period lasts for 7 days. During this time, patients will be monitored to see if their fever goes away and if they experience any other health issues.

Patients will be followed for 30 days after starting treatment. The main focus is to determine if using amoxicillin-clavulanate alone works as effectively as using it together with ciprofloxacin. The study will track various aspects of patient health, including whether the fever returns, if hospital admission becomes necessary, and any side effects from the medications.

The research process

The trial runs in 6 steps – from screening to follow-up. Each step says what happens and what the team monitors.

  1. Step 1

    Initial treatment assignment

    You will be assigned to receive either amoxicillin-clavulanate alone or amoxicillin-clavulanate plus ciprofloxacin

    Both medications are taken by mouth

    The treatment begins when you first experience fever after chemotherapy

  2. Step 2

    First 48 hours

    You will receive a phone call to check your condition

    The medical team will verify if you needed to go to the hospital

    Your vital status will be assessed

  3. Step 3

    Day 4 assessment

    Your temperature will be measured to check if the fever has gone away

    The medical team will verify if any changes to your antibiotic treatment were needed

    Your overall health status will be evaluated

  4. Step 4

    Days 1-7 monitoring

    You will need to keep track of how well you follow the prescribed treatment

    Complete a treatment compliance form each day

  5. Step 5

    Day 14 follow-up

    You will receive a phone call to assess your condition

    The medical team will review your medical records

    They will check if you experienced any fever recurrence

    Your blood test results will be reviewed

    Any side effects will be documented, including: joint pain, tendon pain, confusion, heart rhythm changes, allergic reactions

  6. Step 6

    Day 30 final assessment

    You will receive a final phone call

    The medical team will check if you needed any hospital stays

    Your overall health status will be evaluated one last time

Investigated drugs

Amoxicillin-clavulanate is an antibiotic combination medication that fights bacterial infections. It contains amoxicillin, which kills bacteria, and clavulanate, which helps the amoxicillin work better by preventing bacteria from becoming resistant to it. This medication is commonly used to treat various types of bacterial infections. Ciprofloxacin is an antibiotic that belongs to a group called fluoroquinolones. It works by stopping the growth of bacteria and is effective against many different types of bacterial infections. This medication is often used to treat infections in patients with weakened immune systems. The trial compares using Amoxicillin-clavulanate alone versus using it in combination with Ciprofloxacin for treating fever in patients receiving chemotherapy. Both treatments are given by mouth to patients who don't need to stay in the hospital.

What is already known about the treatment

  • Amoxicillin-clavulanate

    An oral antibiotic combination medication consisting of amoxicillin (a penicillin-type antibiotic) and clavulanic acid, which helps prevent bacterial resistance. This medication works by stopping the growth of bacteria by interfering with their cell wall formation, and is commonly used to treat various bacterial infections. It belongs to the class of beta-lactam antibiotics combined with beta-lactamase inhibitors, making it effective against a broader spectrum of bacteria than amoxicillin alone.

  • Ciprofloxacin

    A broad-spectrum antibiotic medication taken orally that belongs to the fluoroquinolone class of antibiotics. It works by interfering with bacteria's DNA replication process, effectively stopping bacterial growth and multiplication. The medication is commonly used to treat various bacterial infections, particularly those caused by gram-negative bacteria, and is especially effective in treating respiratory, urinary, and systemic infections. When combined with amoxicillin-clavulanate, it provides enhanced coverage against a wider range of bacterial pathogens, particularly useful in treating infections in immunocompromised patients.

Investigated diseases

  • Neutropenia

    A condition where there is an abnormally low count of neutrophils, a type of white blood cell essential for fighting infections. It commonly occurs as a side effect of chemotherapy treatments in cancer patients. During neutropenia, the body's ability to combat bacterial infections is significantly reduced. The condition can develop rapidly after chemotherapy administration and may last for several days. Neutropenia makes patients more susceptible to various infections, particularly bacterial ones.

  • Chemotherapy-induced Fever

    A rise in body temperature that occurs as a complication during cancer treatment with chemotherapy drugs. The fever typically develops when the patient's immune system is weakened by the treatment. This condition often appears during periods of low white blood cell counts. The fever may occur with or without an identifiable infection source. It represents one of the most common complications in patients receiving chemotherapy.
