Study of TX000045 in Participants With Pulmonary Hypertension Due to Interstitial Lung Disease
What this study is about
The primary purpose of this study is to assess the effect of TX000045 on pulmonary vascular resistance (PVR) in participants with pulmonary hypertension secondary to interstitial lung disease (PH-ILD) and to assess the safety and how well patients handle the treatment of TX000045 in participants with PH-ILD.

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Confirmed diagnosis of ILD based on imaging: chest computed tomography (CT) performed within the past 12 months with fibrotic lung disease (greater than or equal to (\>=) 10 percent (%) lung parenchyma with fibrosis) consistent with idiopathic interstitial pneumonia, ILD in association with connective tissue disease, occupational ILD, or chronic hypersensitivity pneumonitis. Chest CTs will be centrally read for eligibility
- 40% predicted less than or equal to (\<=) forced vital capacity (FVC) \<= 80% predicted at screening
- At least ONE of the following is required to undergo the first screening visit: Documented diagnostic right heart catheterization (RHC) within 18 months of screening with mean pulmonary arterial pressure (mPAP) \>= 25 millimeters of mercury (mm Hg), pulmonary capillary wedge pressure (PCWP) \<=15 mm Hg, and pulmonary vascular resistance (PVR) \>=4 Wood units; Documented echocardiogram (ECHO) within 18 months of screening with right ventricular (RV) (or pulmonary artery) systolic pressure \>46 mm Hg or tricuspid annular plane systolic excursion (TAPSE)/ systolic pulmonary artery pressure (SPAP) \<=0.38 and absence of clinically significant left ventricular dysfunction as assessed by the investigator
Exclusion criteria
- Participants have a confirmed or suspected diagnosis of pulmonary hypertension in World Health Organization (WHO) Group 1, WHO Group 2, WHO Group 4, or WHO Group 5
- Participants have received phosphodiesterase type 5 inhibitors, endothelin receptor antagonists, soluble guanylate cyclase stimulators, intravenous (IV) or subcutaneous (SC) prostacyclin analogues within 30 days before the first screening visit, or sotatercept within 180 days before the first screening visit
- Participants have any type of pulmonary and cardiovascular comorbidities as defined n protocol
- Participants who are taking disease-modifying therapy for the underlying interstitial lung disease (ILD) (anti-fibrotics, immunosuppressives, and anti-inflammatory medications) who are not on stable doses for \>30 days before the first screening visit or have initiated new ILD-directed therapies within 90 days before the first screening visit

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
