Trial overview
The available study on Treprostinil Sodium is an open-label, single-arm, non-controlled trial in children with pulmonary arterial hypertension (PAH).[1] It is designed to evaluate safety and tolerability in patients below 18 years of age.[1]
The trial is authorised and has an enrolment of 37 participants.[1]
Who can participate
This study includes paediatric patients under 18 years old with PAH.[1] The brief summary says the study includes both treatment-naive patients, meaning children who have not received treatment before, and patients who were previously treated with commercially available parenteral treprostinil formulations.[1]
Study design and phase
The trial is an interventional study, which means the research team gives the study treatment to the participants.[1] It is described as open-label, so the treatment is known to both the researchers and the participants.[1]
It is also a single-arm and non-controlled study, which means there is no comparison group in this trial.[1] The study is in Phase 3, a later stage of clinical research that often focuses on collecting stronger safety data in a defined patient group.[1]
What is being measured
The primary outcome is the frequency and seriousness of adverse events and adverse drug reactions during the first 5 months of treatment, or 20 weeks plus or minus 1 week.[1] Adverse events are health problems that happen during the study, while adverse drug reactions are problems thought to be related to the study drug.[1]
The study uses CTCAE version 5.0, which is a standard system for grading how serious these events are.[1]
Treatment details in the trial
The trial includes several study drug presentations named TREPaed_10, TREPaed_5, TREPaed_0.5, TREPaed_2.5, and TREPaed_1.[1] The data list each as 155 ng and note subcutaneous and intravenous use.[1]
These details show that the study is examining Treprostinil Sodium in paediatric patients using parenteral routes, meaning the medicine is given outside the digestive tract.[1]
Helpful terms for patients
- PAH: a condition with high pressure in the blood vessels of the lungs.[1]
- Treatment-naive: a patient who has not had the treatment before.[1]
- Parenteral: given by a route other than the digestive system, such as under the skin or into a vein.[1]
- Subcutaneous: given under the skin.[1]
- Intravenous: given into a vein.[1]
- Tolerability: how well patients can handle a treatment without too many problems.[1]
