About this trial

Study LTI-401 is an open-label, multicenter study which will evaluate the safety and tolerability of LIQ861 in subjects who have WHO Group 1 \& 3 PH.

Eligibility criteria

Qualifiers

Males or Females between 18 years to 80 years of age.

Has a confirmed diagnosis of WHO Group 3 PH-ILD based on CT chest imaging performed, which demonstrates evidence of diffuse parenchymal lung disease and FEV1/FVC (absolute values) ≥ 70% and are required to have evidence of pulmonary hypertension (PH) as demonstrated from right heart catheterization (RHC) with the following hemodynamic parameters.

i) Pulmonary vascular resistance (PVR) ≥ 3 Wood Units (WU) and ii) Pulmonary capillary wedge pressure (PCWP) of ≤ 15 mmHg and iii) A mean pulmonary arterial pressure (mPAP) of ≥ 30 mmHg.

An exploratory subset of subjects with ILD: i) Pulmonary vascular resistance (PVR) ≥ 3 Wood Units (WU) and ii) Pulmonary capillary wedge pressure (PCWP) of ≤ 15 mmHg and iii) A mean pulmonary arterial pressure (mPAP) of ≥ 21 mmHg.

Disqualifiers

PH in the Updated WHO Classification Groups 1, 2, 4, or 5.

History of hemodynamically significant left-sided heart disease.

Exacerbation of underlying lung disease or active pulmonary or upper respiratory infections.

Initiation of pulmonary rehabilitation.
