About this study

  1. Based on the applicant's previous work and combined with the clinical medical resources of our unit, tumor cells were isolated from the lesion site of cancer patients, dendritic cells or macrophages were isolated from peripheral blood, and personalized chimeric exosome vaccine was prepared for patients.
  2. To evaluate the safety and tolerability of multiple administration of chimeric exosome vaccine in subjects with hatching or metastatic bladder cancer, explore the maximum tolerated dose (MDT) and dose-limiting toxicity (DLT) in humans, and recommend the safe dose range for the subsequent extended trials and subsequent clinical studies of this product.
  3. To reveal the "double-effect" improvement mechanism of chimeric exosome vaccine on the activation of immune response and the microenvironment of bladder cancer lesions, improve the anti-recurrence treatment effect of bladder cancer, and realize the clinical transformation of "double-target and double-effect" chimeric exosome vaccine in the field of individualized precision treatment of bladder cancer patients.
  4. To explore the clinical application value of this tumor therapeutic vaccine by using the T-cell receptor immunoomics and immunomolecular evaluation technology platform established by previous researchers, and to provide preliminary clinical research results for further vaccine development.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Chimeric exosomal tumor vaccinesBiological

    Tumor cells (lesion site) were isolated from bladder cancer patients, and bladder cancer nuclei were extracted. Monocytes were isolated from peripheral blood of this patient and induced in vitro to obtain APC (DC or macrophage). Apc-tumor chimeric cells were constructed and stimulated with immune stimulator. Chimeric exosomal vaccines were extracted from cell supernatants by differential and hypervelocity centrifugation

  2. Overall survival(OS)

    From the starting date of the enrollment until the date of the first documented disease progression or the date of the death from any cause,whichever comes first

    Measured: 24 months

  3. Safty(adverse events)

    Number of participants with treatment-related adverse events as assessed by CTCAE v5.0

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Chimeric exosomal tumor vaccines in people with Recurrent or Metastatic Bladder Cancer, run by Shanghai Pudong Hospital at 1 site in China.

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 15 inclusion and 22 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: status not confirmed, as of the sponsor's last update on 29 Sep 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. 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?

Results are not available in the source record.

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

Contact Jun Ren (13911568563, jun.ren@duke.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Clinical response rate (time frame: 24 months). The study lists 3 primary outcomes in all. 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 29 Sep 2022.
