Cosmos Trial: Cerebroprotection Of AST-004 in Mild Complicated Traumatic Brain Injuries
The Cosmos Trial is a research study looking into a new medicine called AST-004. It's for people who have recently experienced a mild traumatic brain injury, which means they've had a bump or jolt to the head that affected their brain. The main goal of the study is to check how safe this new medicine is and if it has any unexpected side effects. Researchers will give some people AST-004 and others a placebo, which looks identical but contains no active medicine. They will also measure how the medicine affects certain natural substances in the blood that are linked to brain health. This is an early-stage study (Phase II) to see if AST-004 could be a promising treatment for protecting the brain after an injury.
At a glance
What is this study about?
The Cosmos Trial is a research study focused on a new medicine called AST-004. Its purpose is to see if this medicine can help people who have experienced a mild, but sometimes complicated, traumatic brain injury. A traumatic brain injury happens when a jolt or blow to the head disrupts the normal function of the brain. While the injury might be described as 'mild', it can still have important effects.
Researchers want to understand two main things: first, is AST-004 safe to use, and does it cause any side effects? And second, does it have a protective effect on the brain? To figure this out, some participants will receive the actual medicine, AST-004, while others will get a 'placebo.' A placebo looks exactly like the medicine but doesn't contain any active ingredients. This helps researchers determine if any changes observed are truly due to AST-004 or just the natural healing process or other factors. They will be looking at changes in certain brain markers in the blood over time.
This study is in an early stage (called Phase II), which means it's one of the first times this medicine is being tested in a larger group of people. If the results are promising, it could lead to further studies and potentially help people recover better from brain injuries in the future. The trial aims to find out if AST-004 could be a good way to help protect brain cells and support recovery.
Key takeaways
- The Cosmos Trial is testing a new medicine, AST-004, for mild brain injuries.
- It aims to check the safety and potential brain-protecting effects of AST-004.
- Participants will receive either AST-004 or a look-alike dummy medicine (placebo).
- The study involves regular check-ups, blood tests, and potentially brain scans.
- It's an important early-stage study to understand if AST-004 could be a future treatment.
- Participation is voluntary, and you can withdraw at any time.
Who may be eligible?
To join the Cosmos Trial, you need to be an adult, 18 years old or older. The study is open to both men and women.
The most important requirement is that you've recently had a specific type of mild traumatic brain injury. The study doctors will carefully check if your injury fits the specific criteria for the trial. This is to make sure the medicine is being tested on the group of people it's designed to help.
There might be other health conditions or medicines that would prevent someone from joining, as the researchers need to ensure it's safe for participants and that the study results are clear. Your doctor or the study team will go through all the details with you to see if you are a good fit.
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?
- Have you recently experienced a mild traumatic brain injury?
- Are you able to attend several clinic visits for checks and tests?
- Are you willing to potentially receive a placebo?
- Are you prepared for blood tests and possibly MRI scans?
What does participation involve?
If you decide to take part in the Cosmos Trial, you would receive either the study medicine, AST-004, or a placebo (a dummy medicine). You wouldn't know which one you're getting, and neither would the study team, to keep the results fair. You would have several visits to the clinic or hospital, especially in the first few weeks after your injury. During these visits, the study team would monitor your health closely, ask you about any symptoms, and perform some tests.
These tests would likely include blood samples to check the safety of the medicine and measure certain brain markers. You may also have special brain scans, like an MRI, to see how your brain is responding. You would be followed for up to 30 days or longer to track your recovery and see how the medicine might be affecting you over time. The total involvement could vary but would typically involve regular check-ups and assessments over a period of about a month.

Common questions
What is AST-004?
AST-004 is a new medicine being studied to see if it can help protect the brain after a mild brain injury.
What is a 'mild complicated traumatic brain injury'?
It's a bump or jolt to the head that affects the brain's normal function, and 'complicated' means there might be certain features seen on brain scans or specific symptoms.
What is a placebo?
A placebo is a dummy medicine that looks exactly like the study drug but doesn't contain any active ingredients. It's used to compare against the real medicine.
How long does the study last?
Participants will be followed for a period, with key checks at certain times, up to about 30 days after starting the treatment.
Will I know if I'm getting the real medicine?
No, neither you nor the study team will know whether you are receiving AST-004 or the placebo during the study. This helps ensure fair results.
How to find out more
