药品与企业信息
其他名称：Iloprost、Selexipag
Addition of a prostacyclin pathway agent (inhaled iloprost or oral selexipag) to ongoing dual therapy with an endothelin receptor antagonist and sildenafil as part of therapeutic escalation to triple therapy. The specific agent will be selected according to clinical judgment and availability. Dosing will follow approved labeling and routine clinical practice.
其他名称：Sildenafil
Optimization of sildenafil dose within approved dosing ranges as part of dual therapy with an endothelin receptor antagonist. Dose adjustments will be performed according to clinical practice to achieve maximal tolerated and guideline-recommended dosing without addition of a new PAH pathway agent at randomization.

研究简介（原文）
Pulmonary arterial hypertension (PAH) is a rare and progressive disease characterized by increased pressure in the pulmonary arteries, leading to right heart failure and premature death. Although combination therapy has improved outcomes, many patients remain at intermediate or high clinical risk despite treatment. When patients do not reach low-risk status, treatment escalation is recommended. However, different escalation strategies are used in clinical practice, including increasing the dose of existing medications or adding a third drug that targets a different biological pathway. There is limited prospective randomized evidence directly comparing these approaches. The ASCEND-PAH study is a prospective, randomized, open-label clinical trial designed to compare two therapeutic escalation strategies in adults with PAH who remain at intermediate or high risk despite dual therapy with an endothelin receptor antagonist and sildenafil. Participants will be randomized to either: (1) escalation to triple therapy with the addition of a prostacyclin pathway agent, or (2) optimization of dual therapy by increasing the dose of sildenafil. The primary objective is to compare the proportion of patients who improve their risk category according to the COMPERA 2.0 four-stratum risk model within 3 to 6 months after randomization. Secondary outcomes include changes in functional status, exercise capacity, biomarkers, clinical worsening, safety, and treatment persistence

这项试验目前在中国大陆没有研究中心
这种情况下，直接发"入组咨询"往往会被回复"您所在地区没有中心"。更有效的做法是申请同情用药／扩展准入（由主治医生一同提出），或询问能否到最近的境外中心参加。下面已为您切换到对应的信件版本。
