Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
* Participants must be = 18 to = 75 years at the time of signing the informed consent form (ICF).

3. Guanylate cyclase stimulator (eg, riociguat)
* No change in PH medications (eg, ambrisentan, bosentan, macitentan, sildenafil, tadalafil, riociguat) or dosage for at least 30 days prior to Screening.

* Female participants: Women must be postmenopausal (defined as no menses for 12 months without an alternative medical cause), surgically sterile, (ie, post-tubal ligation for at least 12 months) or using highly effective contraception methods (ie, methods that alone or in combination achieve <1% unintended pregnancy rates per year when used consistently and correctly) from Day 1 to at least 90 days after the last dose of study drug.

* Participation in a cardio-pulmonary rehabilitation program within 1 month of Screening Visit.
* Evidence of thromboembolic disease as assessed by ventilation-perfusion (VQ) scan, pulmonary angiography, or pulmonary computed tomography (CT) scan.
* Active liver disease or hepatic dysfunction.
* History of HIV infection.
* Established diagnosis of hepatitis B viral infection, or positive for hepatitis B surface antigen (HBsAg) at the time of Screening.

* History of abnormal bleeding or bruising.
* History of solid organ transplantation.
* Known or suspected immunodeficiency disorder, including history of invasive opportunistic infections (eg, tuberculosis, histoplasmosis, listeriosis, coccidioidomycosis, pneumocystosis, aspergillosis) despite infection resolution, or otherwise recurrent infections of abnormal frequency, or prolonged infections suggesting an immune compromised status, as judged by the Investigator.
* History of alcohol or drug abuse within 6 months prior to Screening.
* Acute or chronic impairment (other than dyspnea), limiting the ability to comply with study requirements, in particular with 6-minute walk test (eg, angina pectoris, claudication, musculoskeletal disorder, need for walking aids).
* Participants with current or recent (past 30 days) lower respiratory tract infection.
* History of malignancy in the past 5 years, with exception of completely treated in situ carcinoma of the cervix and completely treated non-metastatic squamous or basal cell carcinoma of the skin.
* Change in PH medication (endothelin receptor agonists, phosphoesterase type 5 inhibitors, and guanylate cyclase stimulators or diuretics) between Screening and Baseline.
* Have participated in any other interventional clinical studies within 30 days prior to Screening.
* Current use of cigarettes (as defined by Centers for Disease Control and Prevention) or e-cigarettes.
* Participants who currently inhale marijuana (recreational or medical).
* Pregnant or breastfeeding.
