A Study of ROC-101 in Patients With Pulmonary Arterial Hypertension (PAH) and Pulmonary Hypertension Associated With Interstitial Lung Disease (ILD-PH) (ROCSTAR STUDY)
United States, Australia, Canada40 participantsStarted 2025-10-01
Plain-language summary
This study evaluates the effect of ROC-101 in adults with either Pulmonary Arterial Hypertension (PAH) or Pulmonary Hypertension Associated with Interstitial Lung Disease (ILD-PH). Each eligible participant will receive standard of care (SOC) plus ROC-101 for a 24-week treatment period, followed by a long-term extension period of the study through the end of the program or marketing approval/authorization.

Inclusion criteria
. Must be age 18 or older at the time of signing the informed consent form (ICF). The participant must understand and voluntarily sign an ICF prior to any study-related procedures
. Documented findings on a right heart catheterization (RHC) consistent with a diagnosis World Health Organization (WHO) Group 1 PAH or WHO GROUP 3 PAH
. Symptomatic Pulmonary Hypertension (PH) classified as WHO Functional Class II or III symptoms
. PAH participants: Pulmonary Vascular Resistance (PVR) of ≥ 5 Wood units (≥ 400 dynes/sec/cm-5) and, Pulmonary Capillary Wedge Pressure (PCWP) ≤ 15 mmHg and Mean Pulmonary Arterial Pressure (mPAP) \> 20 mm Hg and ILD-PH participants: PVR of ≥ 3 Wood units (≥ 240 dynes/sec/cm-5) with a maximum enrollment of 5 participants with PVR between 3 and 4 Wood units inclusive (240-320 dynes/sec/cm-5 inclusive) and the remaining 5 participants must have PVR \>4 Wood units (\> 320 dynes/sec/cm-5) and, PCWP ≤ 15 mmHg and mPAP \> 20 mm Hg
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Change in Pulmonary Vascular Resistance (PVR) from Baseline versus at 24 weeks
Timeframe: Baseline and 24 weeks
2
Safety assessments: Number of Participants Who Experienced an Adverse Event (AE)
. Participants on stable background therapy for PAH or ILD-PH.
. Females of childbearing potential (as defined in protocol) must agree to use highly effective contraception (as defined in the protocol)
. Male participants must follow protocol-specified contraception guidance.
. Participants must be able to communicate well with Investigators, understand the study procedures in the ICF and are agreeable to complete the study in accordance with the protocol.
Exclusion criteria
. Diagnosis of PH WHO Groups 2, 4, or 5
. Diagnosis of the following PAH Group 1 subtypes: human immunodeficiency virus (HIV)-associated PAH, PAH associated with portal hypertension, schistosomiasis-associated PAH and pulmonary veno-occlusive disease and/or pulmonary capillary hemangiomatosis
. Positive blood test for hepatitis B virus surface antigen (HBsAg), hepatitis C virus (HCV) antibody (HCVAb) (unless participants have had treatment for HCV and have a negative HCV ribonucleic acid \[RNA\] polymerase chain reaction \[PCR\]) or HIV antibody
. Participants with known hypersensitivity to ROC-101 or any components of its formulations
. History of malignancy within the last 5 years, with the exception of fully excised or treated basal cell carcinoma, cervical carcinoma in-situ, or ≤ 2 squamous cell carcinomas of the skin
. History of clinically significant (as determined by the Investigator) non-PAH related cardiac, endocrine, hematologic, hepatic, immune, metabolic, urologic, pulmonary, neurologic, neuromuscular, dermatologic, psychiatric, renal, and/or other diseases that may limit participation in the study
. Participation in another clinical trial involving intervention with another investigational drug, approved therapy for investigational use, or investigational device within 4 weeks prior to Baseline Visit (unless it is in the follow-up period of an interventional study), or if the half-life of the previous product is known, within 5× the half-life prior to Baseline Visit (Day 1), whichever is longer
. Major surgery within 8 weeks prior to Baseline Visit (Day 1) or major surgery scheduled or planned in the main study. Participants must have completely recovered from any previous surgery prior to the Screening Visit
