Plain-language summary
This Phase 3, 2-part, open-label, multicenter study aims to demonstrate the safety and tolerability of L606 in patients with PAH or PH-ILD. The study will determine the short-term and long-term safety and tolerability of L606 in this patient population.

Inclusion criteria
. Males and females ≥18 and ≤80 years of age.
. Diagnosed with
. PAH belonging to at least 1 of the following subgroups of Group 1 pulmonary hypertension (PH) per European Society of Cardiology/European Respiratory Society Guidelines for the diagnosis and treatment of PH at least 1 year prior to screening. or
. PH-ILD Group 3 European Society of Cardiology/European Respiratory Society Guidelines for the diagnosis and treatment of PH. Subjects with Group 3 PH that is not related to underlying ILD are not eligible.
. Subjects with PAH: Documentation of having PAH as confirmed by RHC meeting the following criteria:
. NYHA functional class II, III, or IV at the screening visit.
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
Safety/Tolerability assessed by incidence of treatment-emergent AEs/SAEs
Timeframe: 2 weeks
2
Safety/Tolerability assessed by incidence of treatment-emergent AEs/SAEs
Timeframe: 12 weeks
3
Safety/Tolerability assessed by incidence of treatment-emergent AEs/SAEs (long-term)
. For subjects with PAH: \>65% of predicted and FEV1/FVC ratio \>65% at screening. For subjects with PH-ILD: \>40% of predicted and FEV1/FVC ratio \>70% at screening.
Exclusion criteria
. LVEF of ≤45% on a historical echocardiogram.
. History of sleep apnea, or left-sided heart disease (including but not limited to aortic or mitral valve disease, pericardial constriction, restrictive or congestive cardiomyopathy, or coronary artery disease) per investigator's discretion.
. Experienced an acute exacerbation of disease or hospitalization for any reason within 30 days of signing the ICF or prior to baseline.
. Musculoskeletal disorder (eg, arthritis affecting the lower limbs, recent hip or knee joint replacement) or any disease that would likely be the primary limit to ambulation or subject is connected to a machine that is not portable enough to allow for a 6MWT.
