About this study

Official title: Construction and Clinical Application of Microfluidic Exosome Chip for Early Diagnosis of Pulmonary Metastasis of Osteosarcoma

Use exosome microfluidic chips to establish a combination of exosome subgroup level (exosome barcode) markers for the early diagnosis of osteosarcoma lung recurrence, and establish the basis of microfluidic chip based exosome biomarker for monitoring the early therapeutic response of the second-line therapy for recurrent osteosarcoma.

Read the detailed description

Osteosarcoma is the most common primary malignant bone tumor in adolescents, and lung metastasis is the main cause of its poor prognosis. Our previous data on the basis of second-line chemotherapy combined with VEGFRi targeted therapy for patients with lung metastases from osteosarcoma showed that some patients with early diagnosis of lung metastases may achieved long-term tumor-free survival upon prompt treatment. However, plasma biomarker for the early detection of recurrent osteosarcoma is still lacking to date. Our preliminary studies indicate that exosome is a potential source of liquid biomarker for the early diagnosis of osteosarcoma lung metastasis. We, therefore, have developed a microfluidic biochip based on nano-zinc oxide microcolumns. This chip can quickly and efficiently screen and capture exosomes and achieve quantitative and qualitative detection of exosome and its subgroups. This technology may be able to achieve early sensitive exosome quantification for lung metastasis of osteosarcoma. But the clinical efficacy and utility of the microfluidic chip based exosome detection for the early diagnosis osteosarcoma recurrence remains to be validated.

This research plan uses our newly developed microfluidic chip technology to capture and efficiently capture exosomes for quantitative and qualitative and marker screening, and establish a combination of exosome subgroups level as a biomarker for the early diagnosis of osteosarcoma lung metastasis.

What is being measured

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

  1. The association of disease recurrence with plasma levels of exosome and its subgroups.

    After the patients were enrolled, MRI of the primary surgical site (enhanced if necessary), chest CT and bone scan were performed for the surveillance of disease recurrence according to the National Comprehensive Cancer Network (NCCN) guideline. The number of total plasma exosome as well as its subgroups (Vim, cluster of differentiation 44 (CD44), Integrins positive, etc.) were measured based on the microfluidic chip. The association of sarcoma recurrence with plasma exosome levels was then determined to validate the clinical efficacy of plasma exosome as a potential liquid biomarker.

    Measured: through study completion, an average of 2 years

Secondary outcomes (3)
  1. The change of plasma exosome level during the postoperative surveillance from baseline

    The exosome and its subgroup levels were measured on the individual basis in comparison to the baseline to study the dynamic change of exosome during the postoperative surveillance from baseline.

    Measured: through study completion, an average of 2 years

  2. The correlation of the therapeutic response with plasma levels of exosome and its subgroups.

    For patients with recurrent disease who start second- or third- line therapy, the number of total plasma exosome as well as its subgroups (Vim, cluster of differentiation 44 (CD44), Integrins positive, etc.) were measured at 1 month post-therapy. We then assess the association of the exosome biomarker with the treatment response, as determined by Response Evaluation Criteria In Solid Tumours (RECIST) 1.1.

    Measured: at 1 month post-therapy

  3. The correlation of microfluidic chip based exosome quantification with conventional approach

    We investigate the correlation of microfluidic chip based plasma exosome levels with the conventional methodologies, such as Nanoparticle tracking analysis (NTA) and Western-blot

    Measured: through study completion, an average of 2 years

Questions about this trial

What is this clinical trial studying?

An observational study of Osteosarcoma and Pulmonary Metastases, run by Ruijin 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 4 inclusion and 5 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: finished, as of the sponsor's last update on 15 Nov 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The association of disease recurrence with plasma levels of exosome and its subgroups. (time frame: through study completion, an average of 2 years). 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 15 Nov 2022.
