About this study

Official title: Patient-derived Xenograft (PDX) Modeling to Test Drug Response for High-grade Osterosarcoma

By obtaining clinical specimens from participants with high-grade bone and soft tissue sarcomas to establish and profile as freshly implanted tumors in mice, the aim of this study is to identify agents with predicted activity in the host patient while also potentially providing them with individualized cancer treatment options

Read the detailed description

Patient-derived xenografts (PDX) are increasingly used as tools for drug development in pre-clinical settings, and have been shown to recapitulate the histology and behavior of the cancers from which they are derived. Although, they have been commonly used productively as pre-clinical disease models to study disease biology and drug response, they have not been used prospectively to inform clinical management. PDX have been employed to inform clinical decision-making in small studies, which have shown high concordance between individual PDX and patient responses to therapy. While encouraging, the role of this approach in bone and soft tissue sarcomas and in the context of genomic drug matching strategies remains undefined. This has created an opportunity to evaluate the utility of PDX as clinical predictors to direct the use of chemo- and targeted therapies in combination with comprehensive genomic and epigenetic analysis for patients with bone and soft tissue sarcomas.

What participants receive

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

  • Molecular Profiling & In Vivo drug testing in PDXOther

    Molecular profiling of host tumour sample and PDX will be performed and analyzed by an expert panel. In vitro drug testing using organoid culture generation may also be performed if sufficient fresh tissue is available. Matched treatment recommendation based on profiling and in vivo PDX drug testing results will be made, if available.

What is being measured

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

  1. Measure of drug sensitive PDX to a panel of drugs as a predictor of clinical response in matched host

    Sensitivity measured by tumor growth inhibition (>80%) or objective tumor response (regression) as per Response Evaluation Criteria In Solid Tumors (RECIST) criteria.

    Measured: up to 2 years

Questions about this trial

What is this clinical trial studying?

An observational study of Osteosarcoma, run by Peking University People's Hospital.

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 7 inclusion and 8 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 30 Nov 2017. 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. 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?

Results are not available in the source record.

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

Contact Tingting Ren, PhD (86-10-88324470, tumorcenter@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Measure of drug sensitive PDX to a panel of drugs as a predictor of clinical response in matched host (time frame: up to 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 30 Nov 2017.
