Natural History Study of Homocystinuria Caused by Cystathionine Beta-Synthase Deficiency (ACAPPELLA)
This study, called ACAPPELLA, is observing people with a rare genetic condition called Homocystinuria (specifically, the type caused by CBS deficiency). Researchers want to understand how this condition progresses naturally in children and adults aged 1 to 65 years who are receiving their usual medical care. The aim is to gather information about their health over time. This research is important because understanding the everyday experiences of people with Homocystinuria can help doctors and scientists develop better ways to manage the condition and improve the lives of those affected in the future. It’s not testing a new medicine, but rather collecting information on the condition itself.
At a glance
What is this study about?
This study is called ACAPPELLA, and its main goal is to better understand a rare genetic condition called Homocystinuria, specifically the type caused by a problem with a protein called Cystathionine Beta-Synthase (CBS). If you or someone you care for has been diagnosed with this condition, this study wants to observe how it affects people aged 1 to 65 years in their daily lives, while they are receiving the medical care they would normally get.
The researchers want to gather detailed information about how Homocystinuria progresses over time. This includes looking at various health aspects and how people live with the condition under their current treatment plans. They aren't testing a new drug or treatment; instead, they are simply observing and collecting information from people who already have the condition. This helps create a clearer picture of the condition's "natural history."
Understanding how Homocystinuria progresses in real-world settings is crucial. This knowledge can help doctors provide better care, predict potential health issues, and develop more effective treatments in the future. By participating, you would be helping researchers learn more about this rare condition, which can ultimately benefit many others.
Key takeaways
- This study aims to understand how Homocystinuria naturally progresses.
- It's open to children and adults aged 1 to 65 with a diagnosis.
- No new treatments or experimental drugs are involved.
- Your regular medical care for Homocystinuria will continue unchanged.
- Your participation helps improve future understanding and care for others.
- You can stop participating at any time without affecting your medical care.
Who may be eligible?
To be part of this study, you would need to have received a medical diagnosis of Homocystinuria. The study is open to both male and female patients, and you need to be between 1 and 65 years old. It's also important that you agree to take part and are able to follow the study's procedures, whatever they might involve.
There are a few reasons why someone might not be able to join. For example, if you have other serious health problems not linked to Homocystinuria that you were born with or that developed shortly after birth. Also, if you’ve recently tried an experimental treatment for Homocystinuria in the last six months, or if you expect to be trying one during the study, you wouldn't be able 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.
- Have I been diagnosed with Homocystinuria (CBS deficiency)?
- Am I between 1 and 65 years old?
- Am I able to understand and agree to take part?
- Do I have any serious health problems not related to Homocystinuria that I was born with?
- Have I used an experimental treatment for Homocystinuria in the last 6 months?
What does participation involve?
The study does not specify particular visits or assessments as it is a natural history study. This means it primarily involves observing your health as you continue with your usual medical care for Homocystinuria. You won't be given any new medications by the study, nor will you undergo experimental treatments. The study will likely involve collecting information from your medical records and possibly asking you about your health and experiences with the condition. The total duration of your participation isn't specified, but it focuses on characterising your clinical course over time.

Common questions
What is Homocystinuria?
Homocystinuria is a rare genetic condition where your body can't properly process a building block of protein called methionine, leading to a build-up of harmful substances.
Is this study testing a new drug?
No, this study is not testing a new drug or treatment. It's observing how Homocystinuria affects people under their usual medical care.
Who can join this study?
Children and adults aged 1 to 65 who have been diagnosed with Homocystinuria and are willing to take part can join.
Will I have to take different medicines?
No, you will continue with your regular medical treatment for Homocystinuria. The study does not involve new or experimental medicines.
What does a 'natural history study' mean?
It means researchers are watching how a condition develops and changes over time in people who are receiving standard care, without interfering or trying new treatments.
