About this study

A single-center, randomized, double-blind, placebo-controlled, dose-escalation clinical study to evaluate the safety and tolerability of intravenous infusion of different doses of the investigational exosome preparation in heart failure subjects receiving left ventricular assist device therapy.

Subjects will receive exosome or placebo once daily for 3 consecutive days, in addition to optimal medical therapy (OMT). The drug category, dosage and administration of OMT will be recorded as concomitant medications and entered into the Case Report Form (CRF). The OMT regimen (including drug type, dosage, route of administration, treatment duration, etc.) will be documented throughout the study. During the study, subjects will undergo efficacy and safety assessments and/or sample collection. After completion of treatment, follow-up visits will be conducted at Day 28, 6 months and 12 months.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of treatment-related serious adverse events within Day 28 after administration of the investigational exosome preparation.

    Measured: within Day 28 after administration of the investigational exosome preparation

Secondary outcomes (15)
  1. Incidence of all adverse events (AEs) and serious adverse events (SAEs) within Day 28 after administration of the investigational exosome preparation.

    Measured: within Day 28 after administration of the investigational exosome preparation.

  2. Incidence and severity of infusion-related reactions within 24 hours after administration of the investigational exosome preparation, including fever, chills, hypotension, hypersensitivity reactions, and cytokine release syndrome (CRS).

    Measured: within 24 hours after administration of the investigational exosome preparation

  3. Occurrence of clinically significant electrocardiographic abnormalities before and after administration of the investigational exosome preparation

    Measured: Baseline (prior to study drug infusion), up to Day 28 post-administration

  4. Occurrence of clinically significant echocardiographic abnormalities before and after administration of the investigational exosome preparation

    Measured: Baseline (prior to study drug infusion), up to Day 28 post-administration

  5. Laboratory abnormalities occurring before and after administration of the investigational exosome preparation

    Measured: Baseline (prior to study drug infusion), up to Day 28 post-administration

  6. Changes in vital signs (blood pressure, heart rate, respiratory rate, body temperature)

    Measured: Baseline (prior to study drug infusion), up to Day 28 post-administration

  7. Incidence of vital sign abnormalities

    Measured: Baseline (prior to study drug infusion), up to Day 28 post-administration

  8. Changes from baseline in Kansas City Cardiomyopathy Questionnaire (KCCQ) score

    KCCQ is a patient-reported health status scale with scores ranging from 0 to 100; higher scores indicate better health-related quality of life.

    Measured: At 6 months and 12 months after administration of the investigational exosome preparation

  9. Changes from baseline in EuroQol 5-Dimension Questionnaire (EQ-5D) utility index

    EQ-5D is a health status questionnaire. The utility index ranges from -0.594 to 1.0; higher utility index indicates better health status.

    Measured: At 6 months and 12 months after administration of the investigational exosome preparation

  10. Changes from baseline in New York Heart Association (NYHA) functional class

    NYHA functional classification (Class I, II, III, IV) assessing heart failure symptom severity.

    Measured: At 6 months and 12 months after administration of the investigational exosome preparation

  11. Changes from baseline in NT-proBNP levels at 6 and 12 months after administration of the investigational exosome preparation

    Measured: at 6 and 12 months after administration of the investigational exosome preparation

  12. Changes from baseline in echocardiographic parameters including LVEF, LVEDD, and LVESD at 6 and 12 months after administration of the investigational exosome preparation

    Measured: at 6 and 12 months after administration of the investigational exosome preparation

  13. Changes from baseline in 6-minute walk test (6MWT) distance at 6 and 12 months after administration of the investigational exosome preparation

    Measured: at 6 and 12 months after administration of the investigational exosome preparation

  14. Time from administration of the investigational exosome preparation to the first occurrence of all-cause death or debilitating stroke

    Measured: at 12 months after administration of the investigational exosome preparation

  15. Time from administration of the investigational exosome preparation to all-cause death

    Measured: at 12 months after administration of the investigational exosome preparation

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Exosome Preparation in people with Heart Failure, run by Yining Yang.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 28 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 20 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Jing Tao, MD, PhD (8618935903292, taojing_xj@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of treatment-related serious adverse events within Day 28 after administration of the investigational exosome preparation. (time frame: within Day 28 after administration of the investigational exosome preparation). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Oct 2026.
