PLX-PAD is a cell-based product made of allogeneic Mesenchymal-like Adherent Stromal Cells (ASCs), derived from human full-term placentas following an elective caesarean section. This year-long study will evaluate the safety of three different dose levels of PLX-PAD, each given as a single intravenous infusion. This study will also evaluate effects that PLX-PAD may have on PAH, such as changes in the ability to exercise and on other tests used to measure the disease severity.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Summary of inclusion and exclusion criteria.\n\nEligible subjects:\n\n* Are between 18 and 75 years of age\n* Have a minimum weight of 45 kg\n* Have a diagnosis of idiopathic or heritable PAH, PAH associated with connective tissue disease (CTD), PAH associated with repaired congenital systemic-to-pulmonary cardiac shunt (at least one year since repair), or PAH associated with appetite suppressant/drug or toxin use confirmed by RHC\n* Have a current WHO functional class II or III designation\n* Have been stabilized, without dose changes for at least 30 days prior to the Screening visit on at least two approved PAH medications (e.g., PDE-5 inhibitor, ERA, prostanoid \\[as inhalation or infusion\\]); or IV prostanoid monotherapy.
