A Phase 2 Study to Evaluate Efficacy, Safety, and Pharmacokinetics of PBF-999 in the Treatment of Patients with Prader-Willi Syndrome.

This research study is testing a new medicine called PBF-999 for people who have Prader-Willi Syndrome. The main aims are to find out if the medicine is safe and if it causes any side effects. We also want to see how well it works to help people with their condition. Another part of the study is to understand how the medicine is absorbed and used by the body. This is an early stage of testing (called a Phase 2 study), where a small group of people try the medicine to help us learn more before it can be offered to more people. Participants will take PBF-999 or a dummy pill (placebo) to see the difference.

Prader-Willi Syndrome

What is this study about?

This study is about a new medicine, PBF-999, for people who have Prader-Willi Syndrome. Prader-Willi Syndrome is a complex genetic condition that affects many parts of the body. People with Prader-Willi Syndrome can experience a range of symptoms, and researchers are always looking for new ways to help manage these.

In this study, we are trying to find out if PBF-999 is safe to use and what effects it might have. This is an important step because before any new medicine can be approved for general use, it needs to be thoroughly tested. We will be looking closely at any side effects people experience, which we call 'adverse events', to make sure the medicine is well-tolerated. We will also be using questionnaires to understand how the medicine might be affecting people's quality of life and general well-being.

We'll also collect some information about how the body handles PBF-999, such as how much of the medicine gets into the blood and how long it stays there. This helps us understand the best way to give the medicine. By carefully studying these things, we hope to learn if PBF-999 could be a helpful new treatment option for people with Prader-Willi Syndrome in the future.

Key takeaways

This study is testing a new medicine (PBF-999) for Prader-Willi Syndrome.
It aims to check if the medicine is safe and how well it works.
Participants will receive either PBF-999 or a dummy pill (placebo).
It's open to adults aged 18 and older, both men and women.
You'll have regular hospital visits for health checks and questionnaires.
You can stop participating at any time you wish.

Who may be eligible?

To be part of this study, you need to be at least 18 years old. There's no upper age limit, so people of all adult ages can take part. The study is open to both men and women.

More specific details about who can and cannot join will be discussed by the study team. For example, they will check your medical history to make sure taking part is safe for you. It's important that you meet all the study requirements to ensure the results are accurate and reliable.

If you're interested, the research team will review your health information and explain everything carefully to see if this study is right for you.

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 a diagnosis of Prader-Willi Syndrome?
Are you able to attend regular appointments at the study clinic?
Are you comfortable potentially receiving a placebo (dummy pill) instead of the active medicine?
Are you willing to provide blood and urine samples?

Answer every question to see your result.

What does participation involve?

If you decide to take part in this study, you'll be given either the new medicine PBF-999 or a 'dummy' pill (called a placebo). A placebo looks just like the real medicine but contains no active ingredients. Neither you nor the study team will know if you are taking the actual medicine or the placebo. This helps us get clearer results.

Taking part will involve regular visits to the study clinic. During these visits, the study team will carry out health checks, ask you questions about how you're feeling, and take blood or urine samples. They might use questionnaires to understand how the treatment is affecting you and measure certain body markers. The exact number of visits and their individual length will be explained by the study team, along with the total duration you'll be involved in the study.

Potential risks and benefits

Taking part in this study might offer you the chance to receive a new medicine that could potentially help with Prader-Willi Syndrome, which might not be available otherwise. Participating also helps doctors learn more about the condition and how to treat it, which could help many other people in the future. However, there's no guarantee that the medicine will help you, and it could cause side effects, just like any medicine. Some side effects might be mild, while others could be more serious. All procedures also carry some risks, such as discomfort from blood tests. You will be closely monitored by the study team, and you are free to leave the study at any time, for any reason, without it affecting your usual medical care.

Common questions

What is Prader-Willi Syndrome?

Prader-Willi Syndrome is a complex genetic condition that affects many parts of the body, including growth, development, and appetite.

What is a 'Phase 2' study?

A Phase 2 study is an early stage of testing a new medicine. It helps us learn more about if the medicine is safe, how well it works, and what doses might be best, after initial safety checks.

What is a 'placebo'?

A placebo is a 'dummy' pill that looks just like the study medicine but doesn't contain any active ingredients. It's used to compare against the real medicine to see its true effects.

Will I know if I'm getting the real medicine or the placebo?

No, neither you nor the study team will know. This is called 'blinding' and helps ensure the study results are as fair and accurate as possible.

What does 'adverse events' mean?

Adverse events are any unwanted or unexpected medical problems that happen during a study. They are carefully monitored to understand the safety of the medicine.
