药品与企业信息

Inhaled Treprostinil (Tyvaso Nebulizer)药物

Participants will receive inhaled Treprostinil (Tyvaso nebulizer), 6 µg per breath, administered four times daily for 4 weeks. The starting dose will be 3 breaths per session. The dose will increase by 1 breath per session each week, as tolerated, to a target of 6 breaths per session by week 4. If adverse effects occur, participants will remain at the highest tolerated dose. The drug will be administered using the Tyvaso inhalation system provided by United Therapeutics. No changes to baseline COPD maintenance medications are allowed during the treatment period. Participants will be monitored for safety throughout the study.

研究简介（原文）

The goal of this clinical trial is to evaluate whether inhaled Treprostinil (Tyvaso) can improve oxygen delivery and blood flow in the lungs in adults (age ≥40) with chronic obstructive pulmonary disease (COPD) and hypoxemia who have less severe reduction in lung blood volume (diffusing capacity of the lungs for carbon monoxide \[DLCO\] ≥45%). The main questions it aims to answer are: 1. Does inhaled Treprostinil increase pulmonary capillary blood volume in ventilated lung regions, as measured by hyperpolarized xenon-129 magnetic resonance imaging (HP129Xe MRI)? 2. Does inhaled Treprostinil improve oxygen delivery (measured as red blood cell \[RBC\] chemical shift) and maintain or only slightly change pulmonary vascular resistance (measured by RBC oscillation amplitude)? 3. Can pre-treatment MRI parameters (RBC transfer and RBC oscillation amplitude) predict who will respond to inhaled Treprostinil? Participants will: * Use the Tyvaso nebulizer (inhaled Treprostinil) 4 times daily for 4 weeks, starting at 3 breaths per session and increasing to a maximum of 6 breaths per session as tolerated. * Undergo HP129Xe MRI before and after treatment to assess regional lung function and oxygen exchange. * Complete pulmonary function tests (PFTs), 6-minute walk tests (6MWT), and echocardiograms at the beginning and end of the study. * Be monitored for adverse events, with a phone check-in midway through and after the treatment period.

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。

Dear Study Team,

I am a patient in China and I am interested in participating in your clinical trial:

Study Title: Inhaled Treprostinil (Tyvaso Nebulizer) For COPD Patients With Hypoxemia
ClinicalTrials.gov Identifier: NCT07037836
Sponsor: Bastiaan Driehuys
Investigational product: Inhaled Treprostinil (Tyvaso Nebulizer)

About me:
- Age: (please fill in)
- Sex: (please fill in)
