- Ages 18 years and older
- All sexes
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- Subjects (≥18 years old) receiving oral Revatio 20 mg TID for PAH within the approved indication (EU Summary of Product Characteristics) for a minimum of 1-month and who, in the investigator's opinion, have demonstrated good tolerability. Subjects with PAH who are nil by mouth for any reason (eg, elective surgery or medical procedure, TPN feeding, gastrointestinal disturbance etc) may also be included in the study provided they are haemodynamically stable (see Inclusion Criterion 4) and the 6 hour period of blood pressure and pulse monitoring in the study does not interfere with any planned medical or surgical intervention.
- Evidence of a personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the study.
- Subjects who are willing and able to comply with scheduled visits, treatment plan and study tests and procedures.
Who cannot join
- Any subject receiving Revatio outside ('off-label') of the current Summary of Product Characteristics (SmPC).
- Other severe acute or chronic medical or psychiatric condition that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the subject inappropriate for entry into this study.
- Introduction of potent CYP 3A4 inhibitors (eg, ketoconazole, itraconazole and ritonavir) within the previous 1 month of screening.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing sildenafil in people with Hypertension, Pulmonary, run by Pfizer's Upjohn has merged with Mylan to form Viatris Inc. at 1 site in Belgium.
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 3 inclusion and 3 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 1 Feb 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Belgium. 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 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.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Pharmacokinetic concentrations of plasma sildenafil and its metabolite (time frame: 6 hours). The study lists 3 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 NCT00800592, 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 1 Feb 2021.
