A Phase 1, Open-Label, 2-Period, 2-Formulation, Within-Subject Crossover Comparative Pharmacokinetic, Pharmacodynamic, and Safety Study of 1 Dose Level of Aspirin for Injection and Oral Aspirin Tablets in Healthy Adult Human Subjects Under Fasting Conditions.
This research is looking at two different ways to take aspirin: as an injection and as a tablet. We want to see how these two forms behave inside the body of healthy adult volunteers. This includes how quickly the aspirin gets into the bloodstream, how it affects the body, and if there are any side effects. Both forms of aspirin will be given to the same group of volunteers, just at different times, so we can directly compare them. This is a very early stage 'Phase 1' study, which means it helps us understand the basics of a medicine before it's tested in people who are unwell. The goal is to make sure medicines are safe and work as expected.
At a glance
What is this study about?
Imagine you have a headache and take an aspirin. But what if you couldn't swallow a tablet, or needed the medicine to act super fast? This study is designed to answer fundamental questions about aspirin when it's given in two different ways: as a tablet you swallow, and as an injection. We're interested in how the body takes in each form, what happens to it once it's inside, and how quickly it leaves the body. This is crucial for doctors to know which method might be best in different situations, for example, in an emergency versus for everyday use.
This type of study often involves healthy volunteers because it helps us understand the medicine's basic properties without other health conditions making things more complicated. It's an important early step in developing new treatments or finding new ways to use existing ones safely and effectively. By comparing the injection and the tablet directly in the same people, we get very clear results about their differences.
The information gathered from this study, while not directly treating a disease, is vital for future research. It helps scientists and doctors decide if one form of aspirin might be better than another for certain medical needs, or if it's safe to use. It's all about making sure medicines are well-understood and can be used in the best possible way for patients in the future.
Key takeaways
- This study compares aspirin given as a tablet versus an injection.
- It's for healthy adults, aged 18 and over.
- The main goal is to understand how the body processes each form and if they are safe.
- Participation involves receiving both forms of aspirin at different times.
- Results from this study help improve future medical treatments.
Who may be eligible?
This study is looking for healthy adults to take part. This means we're looking for individuals who generally feel well and don't have any significant ongoing health problems. The aim is to study how the medicine works in a 'typical' healthy body, without other illnesses that might affect the results.
You need to be at least 18 years old to be considered for this study. There isn't an upper age limit mentioned, so older adults who are healthy may also be able to join. Both men and women are welcome to participate.
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 consider yourself generally healthy?
- Are you able to follow study instructions, including fasting?
- Are you comfortable with receiving injections and having blood samples taken?
What does participation involve?
If you decide to take part in this study, you would receive both aspirin in tablet form and aspirin as an injection at different times. The study is designed to compare these two forms directly within each person. You would likely have a screening visit first to check that you are healthy enough for the study. After that, you would have two separate study periods where you would receive one form of aspirin and be closely monitored for several hours or perhaps a full day. There would be follow-up visits or calls to check on you afterwards. More details about the exact number of visits, how long each visit would last, and the full duration of your involvement, would be explained by the study team.

Common questions
What is a 'Phase 1' study?
A Phase 1 study is a very early stage of research, usually done in healthy volunteers, to see how a new medicine or a new way of giving an old medicine, works in the body and if it's safe.
Why are healthy people needed for this study?
Using healthy people helps researchers understand the basic effects of the medicine without other health conditions making the results complicated. It's about getting a clear picture of the medicine itself.
What does 'pharmacokinetic' mean?
It's a scientific word that basically means how your body handles the medicine – how it takes it in, where it goes, how it's changed, and how it leaves your body.
What does 'pharmacodynamic' mean?
This is about what the medicine does to your body – how it affects your body's systems, like blood clotting or pain reduction, for example.
Will I have to fast for the study?
Yes, the study mentions it will be done under 'fasting conditions,' meaning you would likely not be allowed to eat or drink (except water) for a certain period before and during parts of the study visits.
