Clinical trials
A ‘clinical trial’ is a research study in which people agree to test a potential new treatment to prevent or improve a disease or medical condition. A clinical trial also looks at how participants react to the potential new treatment and if any unwanted effects occur. This helps to determine if the new investigational treatment works, is safe, and is better than those that are already available. Many clinical trials also compare existing treatments or test new ways to use or combine existing treatments.
All new drugs must be tested in clinical trials before they can be prescribed to patients. Without children and people taking part in these research studies, we would have no new drugs to help others with their condition. Diverse groups of participants are included in clinical trials because drugs may affect people differently based on their age, sex, gender and ethnicity.
The Libelula clinical trial of Debio 4326 for children with central precocious puberty (CPP)
The Libelula clinical trial will assess a new drug (Debio 4326) for children with central precocious puberty (CPP). Girls and boys with CPP may have social and emotional problems because they feel different from their peers. Hormonal treatment to slow down puberty can last for several years, and the existing injectable treatments need to be taken every 1, 3, or 6 months. In this clinical trial, the study drug will be given once a year.
Your child may be able to take part if they:
-
- – are aged 5 to 8 years, inclusive
- – have CPP
- – are being treated with gonadotropin-releasing hormone agonist (GnRHa) therapy for minimum a year prior to entering this study
Children of other ages may be able to take part in this clinical trial. When contacting a clinical trial doctor, they will be able to tell you if children under 5 or older than 8 can now take part in the study.
Participation in the study may last for up to 2 years and 4 months and may require a maximum of 21 study visits.
Information on Triptorelin history
The Libelula study drug (Debio 4326) is triptorelin, which belongs to the gonadotropin-releasing hormone agonist (GnRHa) family used as standard of care in Central Precocious Puberty. GnRHa treatment can reduce the level of sex hormones and slow down the progression of puberty and physical development.
The Libelula study drug formulation is designed as an extended-release formulation of triptorelin (12-month formulation) and will be administered as an intramuscular injection. An extended-release formulation means that the drug is slowly released in the body over a prolonged period of time.
With this new formulation, the Libelula Study intends to further reduce the frequency of injections, and consequently the frequency of potential injection-site reactions. Moreover, this formulation will be especially beneficial to children who are diagnosed with CPP very early on in their childhood and require long-term GnRHa treatment to suppress the progression of the precocious puberty.

Phases
When a potential new medication is being developed, it is first tested in a laboratory setting. If the results are positive, the drug may enter a clinical trial program. This means that it will be tested in humans in several ‘phases’ of study.
Phase I = Safety evaluation. The very first administration in humans, typically carried out in a small group of healthy volunteers to assess if the drug is safe.
Phase II = Efficacy evaluation. The first trials in patients with the intended disease to check if the drug works efficiently and if there are any unwanted side effects.
Phase III = Confirming findings. Trials in large numbers of patients that generally compare the drug to the best treatments available.

Talk with your medical doctor
If you are interested in participating in an upcoming clinical trial (can be also referred to as a clinical study), ask your doctor if a clinical trial might be right for you. Your doctor knows both you and your health history, which is invaluable in making this decision. Your doctor can help you gather the information needed to locate a trial and help you identify what questions might be important to ask the clinical trial doctor before deciding to participate.
