CHASE Registry of Patients With Pulmonary Hypertension Receiving Targeted Therapy

Study Purpose

CHina Registry for the chAracteristics and Management strategieS of patiEnts With Pulmonary Hypertension Using Targeted Therapy (CHASE Study)

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Inclusion Criteria:

  • - Sign informed consent; - Between the ages of 18 and 85; - Clinical diagnosis of pulmonary hypertension, using or planning to use pulmonary hypertension targeted drugs (including any one or more of the following: prostacyclin analogues, endothelin receptor antagonists, phosphodiesterase inhibitors, soluble guanylate cyclase agonists and prostacyclin receptor agonists).

Exclusion Criteria:

- Have a history of mental illness or drug or poison addiction, and can not sign informed consent or can not cooperate with the experimental study; - Patients with malignant tumor and other diseases and life expectancy of less than half a year; - Short-term (less than 2 weeks) patients taking targeted drugs for pulmonary hypertension

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

The purpose of this study was to establish the clinical characteristics and treatment strategies of targeted pulmonary hypertension patients in China: a multicenter, prospective case registry (CHASE) study to describe the clinical characteristics, treatment used, disease progression, and outcomes (e.g., death, hospitalization) of patients taking targeted drugs in real-world clinical practice. This study will collect high-quality real-world data that can be used as a standalone dataset or combined with other data sources to address critical issues in the PH field. This is a prospective, observational, multicenter study. The expected number of enrolled cases for the entire study: at least 5000; No experimental group and control group were divided. Patients were followed up every 6 months ±2 weeks after enrollment for 3 years. The study selected patients who signed informed consent, aged 18-25 years, clinically diagnosed with pulmonary hypertension, and were applying or planning to apply targeted drugs for pulmonary hypertension as the study objects. The primary endpoint was the incidence of clinical exacerbations at 1 year after enrollment. Secondary endpoints were all-cause mortality at 1, 2, and 3 years after enrollment, rate of lung transplantation or combined cardiopulmonary transplantation, 6-minute walking distance, NT-proBNP level, WHO cardiac function grade, ratio of right ventricular end-diastolic diameter to left ventricular end-diastolic diameter, pulmonary hypertension targeted drug regimen, and incidence of associated adverse reactions.
