Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

  3. Diagnosed as chronic Stanford type B aortic dissection;
  4. Maximum diameter of the intimal tears is between 2mm and 20mm;
  5. Important branch vessels will not be covered after intimal tears closure;
  6. Aortic endovascular treatment can be performed with appropriate arterial access.

Exclusion Criteria:

  1. Diagnosed as acute, subacute aortic dissection;
  2. Intermural hematoma, aortic ulcer, pseudoaneurysm, and severe aortic calcification;
  3. The minimum distance between the intimal tears of the aortic intimal flaps and the root of the intimal flaps is less than the radius of the patch to be used (the patch cannot be deployed flat);
  4. Pregnant, breastfeeding or cannot contraception during the trial period;
  5. Participated in clinical trials of other drugs or devices during the same period;
  6. The same operation requires intervention in other vascular diseases (such as coronary artery, renal artery, superior mesenteric artery, etc.), and the postoperative drug treatment plan is therefore affected;
  7. Allergic to contrast agents, anesthetics, patches, and delivery materials;
  8. Cannot tolerate anesthesia;
  9. Severe liver, kidney, lung, and heart function abnormalities before surgery [Serum creatinine exceeds 2 times the upper limit of normal; Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) exceeds 5 times the upper limit of normal; Serum total bilirubin (STB) more than 2 times the upper limit of normal; Left ventricular ejection fraction is lower than normal by cardiac color Doppler ultrasound examination];

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Endopatch System
Participants will be treated with Endopatch System
Device: Endopatch System
The patch system for aortic dissection tear is composed of a dissection tear patch system and an adjustable bend conveyor. The patch system is composed of a patch and a conveying steel cable. The patch is pre-installed on the conveying steel cable.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
No major adverse events within 30 days after surgery.
Time Frame: 30 days after operation
Major adverse events within 30 days after operation refer to all-cause death, myocardial infarction, ischemic stroke, respiratory failure, liver failure, renal failure, intestinal necrosis, paraplegia, and amputation within 30 days after operation. Among them, renal failure refers to long-lasting dialysis, kidney transplantation, or other fatal results. Intestinal necrosis is intestinal ischemia that requires bowel resection or other fatal consequences. Severe lower limb ischemia refers to new severe limp or resting pain after surgery.
30 days after operation
The success rate of entry tears closure 6 months after operation.
Time Frame: 6 months after operation
The success rate of intimal tears closure at 6 months is a composite index, including immediate technical success after the operation and no leakage of the intimal tears sealed by the DSA 6 months after the operation, no displacement of the patch, and no second occurrence during the follow-up period.
6 months after operation

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
All-cause mortality, aortic dissection-related mortality, serious adverse events, and device-related adverse events.
Time Frame: 30 days, 6 months, and 12 months after operation
  1. All-cause mortality 30 days, 6 months, and 12 months after operation;
  2. Mortality related to aortic dissection 30 days, 6 months, and 12 months after operation;
  3. Incidence of serious adverse events 30 days, 6 months, and 12 months after operation;
  4. Incidence of device-related adverse events 30 days, 6 months, and 12 months after operation.
30 days, 6 months, and 12 months after operation
False lumen thrombosis of the descending thoracic aorta 1 month, 6 months, 12 months after operation

False lumen thrombosis of the descending thoracic aorta 1 month, 6 months, 12 months after operation.
1 month, 6 months, 12 months after operation
