Evaluation of the Pharmacokinetics of Subcutaneous Administration of Piperacillin/Tazobactam: An Open-Label, Multicentric, Non-Inferiority Randomized Clinical Trial (STUPITA01)
This study is looking at a common antibiotic called piperacillin/tazobactam, often used for serious infections. Currently, it's given through a drip into a vein. Researchers want to find out if giving this medicine as an injection under the skin (subcutaneous injection) works just as effectively. They will compare how much of the medicine gets into your body and stays there when given this new way, compared to the standard drip. The aim is to see if the injection under the skin is 'non-inferior,' meaning it's at least as good as the current method. If successful, this could make treatment easier and more comfortable for patients with various infections, making it a valuable option for future care.
At a glance
What is this study about?
This study is all about finding a new way to give an important antibiotic medicine called piperacillin/tazobactam. This medicine is often used to treat various infections. Right now, if you need this antibiotic, it's usually given through a drip into your arm (intravenous or IV administration), which means you might need to stay in hospital or have a nurse visit for each dose.
The main goal of this research is to see if giving this same antibiotic as an injection just under the skin (subcutaneous injection) works just as well. Researchers will be carefully measuring how much of the medicine gets into your bloodstream and how long it stays there when given both ways. They want to make sure the injection under the skin delivers the medicine to your body in a way that is at least as effective as the current drip method. This is what we mean by 'non-inferior.'
If this study shows that the under-the-skin injection works just as well, it could be a really good option for the future. It might mean patients could have their treatment more easily, perhaps even at home, making it more comfortable and convenient than regular drips. The study will also be checking to see if people get better from their infections and if there are any side effects with this new way of giving the medicine.
Key takeaways
- This study explores a new way to give a common antibiotic (piperacillin/tazobactam).
- It aims to see if an injection under the skin works as well as a drip into the vein.
- The goal is to make antibiotic treatment potentially easier and more comfortable for patients.
- Adults aged 18 and over who need this antibiotic for an infection may be eligible.
- Participation involves receiving the antibiotic and providing blood samples for testing.
Who may be eligible?
To join this study, you need to be an adult, aged 18 or older. Both men and women can take part.
More details about who can join will be discussed with you by the study team. They will check your medical history to make sure the study is a safe and suitable option for you.
Generally, participants will be people who need treatment for an infection that requires this specific antibiotic. The study team will explain everything to you clearly and answer any questions you have about whether you can take part.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you 18 years old or older?
- Do you have an infection that your doctor thinks needs treatment with piperacillin/tazobactam?
- Are you able to attend appointments for blood tests and treatment doses?
- Have you discussed your current health conditions and other medicines with your doctor?
- Are you comfortable with the idea of receiving an injection under the skin, or through a drip into a vein, as part of the study?
What does participation involve?
If you decide to take part, you would receive the antibiotic piperacillin/tazobactam, either through a standard drip into your vein or as an injection under your skin, as determined by the study design. The specific details of how often you receive the medicine would be explained by the study team.
Throughout the study, you would have regular blood samples taken. These samples help the researchers understand how well the medicine is working in your body. They'll measure how much of the antibiotic is in your blood at different times after you receive your dose. You will also have regular check-ups with the study team to monitor your infection and any side effects you might experience. The total length of your participation would depend on your treatment plan for the infection, but would include follow-up checks after your treatment finishes.

Common questions
What is piperacillin/tazobactam?
It's an antibiotic medicine often used to treat various types of serious bacterial infections.
What does 'subcutaneous administration' mean?
It means the medicine is given as an injection just under your skin, rather than directly into a vein.
Why is this study important?
It could lead to a more convenient way to give this important antibiotic, potentially making treatment easier for patients in the future.
Will I know if I'm getting the injection or the drip?
The study team will explain how the treatment is assigned and what you can expect as a participant.
What does 'non-inferiority' mean in this study?
It means the study aims to show that giving the antibiotic under the skin works at least as well as giving it through a drip into a vein.
