- All sexes
- No healthy volunteers
- Child
Who may be able to join
- Currently have a diagnosis of PAH that is either:

About this study
Official title: A Multiple Ascending Dose Study of Tadalafil to Assess the Pharmacokinetics and Safety in a Pediatric Population With Pulmonary Arterial Hypertension
The purpose of this study is to see how much study drug is in the blood of children with pulmonary arterial hypertension (PAH) after dosing to establish the correct dose for further clinical research.
Read the detailed description
During Period I, tadalafil will be administered orally, once daily, at a low dose for approximately 5 weeks followed by a high dose for approximately 5 weeks. Dose levels are calculated based on body weight cohorts. Heavy weight cohort >=40 kg, middle weight cohort >=25 kg to <40 kg. Light weight cohort<25 kg. Participants who complete Period 1 may continue taking tadalafil in Period 2 for at least 2 years. Starting dose will not exceed the maximum weight range dose established in Period 1 and after the first 3 months of Period 2, the dose may be adjusted based on available safety and efficacy information.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Tadalafil- Tablet or Oral suspension in people with Pulmonary Arterial Hypertension, run by Eli Lilly and Company at 16 sites in 6 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 9 Oct 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 16 sites in United States, France, Poland, Canada, Spain and 1 more country. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 5 Feb 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Population Pharmacokinetics: Area Under the Concentration Curve Versus Time at a Dosing Interval at Steady State (AUCtau) for Tadalafil (time frame: Period 1: Pre Dose and 2, 4, 8, 12, and 24 Hours Post Dose on Days 1, 14 and 49; with single dose measures on Day 1 and steady-state measurements on Days 14 and 49). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01484431, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Oct 2019.
