A Phase 2, Open-Label, Extension Study to Evaluate the Long-Term Safety, Tolerability, and Efficacy of BMN 111 in Children with Achondroplasia
This study is a long-term look at a medication called Voxzogo for children who have achondroplasia. Achondroplasia is a condition that affects how bones grow. The main purpose of this research is to see how safe Voxzogo is over a longer period. Researchers will carefully check for any side effects and how well children tolerate the medicine. They will also be measuring children's growth to see if the medicine helps them get taller. This study is an extension, meaning it's for children who have already been taking part in an earlier study of Voxzogo. It helps us understand the long-term impact of the treatment on growth and overall health in children.
At a glance
What is this study about?
This research study is about a medicine called Voxzogo, which is being investigated for children with achondroplasia. Achondroplasia is a genetic condition that affects bone growth, leading to shorter limbs and other specific physical features. This particular study is an 'extension' study, meaning it's for children who have already been taking part in an earlier study of Voxzogo. The main goal is to continue watching these children over a longer period to understand the full picture of how the medicine affects them.
The most important thing researchers are looking at in this study is called 'safety.' This means they want to make sure the medicine is not causing any serious problems or side effects over time. They will also be checking to see how well children are coping with the medicine and if they have any difficulties taking it. Understanding the long-term safety of new medicines is incredibly important to ensure they can be used effectively and responsibly.
Beyond safety, researchers are also very interested in how Voxzogo might affect children's growth. They will be carefully measuring things like how quickly children grow taller each year and what their final adult height might be. They’ll also look at how different parts of the body grow in proportion to each other. This information will help doctors understand if Voxzogo can help children with achondroplasia grow closer to what is considered a typical height and body proportion.
Key takeaways
- This study is examining the long-term safety of Voxzogo for children with achondroplasia.
- It also checks if Voxzogo helps children grow taller and improves body proportions.
- Only children who have already participated in a previous Voxzogo study can join.
- Regular health checks, measurements, blood tests, and scans will be part of the study.
- The study helps understand the long-term effects of this treatment.
- Participation is voluntary, and you can withdraw at any time.
Who may be eligible?
This study is open to both boys and girls of any age who have achondroplasia. It is specifically designed for children who have already been part of a previous study where they received Voxzogo.
This means that if your child has achondroplasia and has already participated in an earlier research study involving Voxzogo, they might be able to continue taking part in this long-term extension study.
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.
- Does your child have achondroplasia?
- Has your child already participated in a previous research study involving Voxzogo?
- Is your child able to attend regular clinic visits and assessments?
- Are you comfortable with your child receiving regular injections and having various medical tests?
What does participation involve?
If your child takes part in this study, they will continue to receive the Voxzogo medication as an injection. Researchers will regularly check your child's health and growth. This will involve appointments where doctors will carry out physical examinations, like checking their heart, and taking regular measurements of their height, weight, and different body parts. You or your child may also be asked about any side effects experienced.
There will also be regular blood and urine tests to check general health, and some imaging like X-rays or special scans to look at bone growth. Heart scans (echocardiograms) and checks on hip health will also be part of the assessments. The total duration of participation in this long-term study will depend on how long the researchers decide to continue gathering information about the treatment.

Common questions
What is achondroplasia?
Achondroplasia is a condition that affects how bones grow, leading to shorter limbs and other specific physical features.
What is Voxzogo?
Voxzogo is a medicine being studied to see if it can help improve growth in children with achondroplasia.
Why is this called an 'extension study'?
It's an extension study because it's for children who have already been part of an earlier study looking at Voxzogo. It allows researchers to follow them for a longer time.
Will my child definitely grow taller if they take part?
The study aims to see if Voxzogo helps with growth, but there's no guarantee of how much your child might grow. Researchers will carefully measure their progress.
Can we stop participating in the study at any time?
Yes, you have the right to withdraw your child from the study at any time, for any reason, without it affecting their regular medical care.
