Study Description

Brief summary:

hMe-Seal is a low-input whole-genome cell-free 5hmC sequencing method based on selective chemical labeling. It uses β-glucosyltransferase (βGT) to selectively label 5hmC with a biotin via an azide-modified glucose for pull-down of 5hmC-containing DNA fragments for sequencing. After selectively constructing 5hmC library, highthroughput-sequencing will be performed on an Illumina Nextseq-500 instrument. By ways of Rawdata processing, differential loci between Osteosarcoma group and control group will be detected to indentify specific epigenetic biomarkers of Osteosarcoma. From our previous trials, we identify geno sequencing related to beta-catenin pathways might have some relationship with osteosaroma primary or secondary drug resistance. Thus in this trial we try to further explore the drug resistance mechanism for advaced osteosarcoma second resistance to the combination therapy of Famitinib and Camrelizumab.

  • Condition or Disease:Drug Resistance to Famitinib and Camrelizumab

Detailed Description


Study Design
  • Study Type: Observational [Patient Registry]
  • Estimated Enrollment: 40 participants
  • Observational Model: Case-Only
  • Time Perspective: Prospective
  • Official Title: Indentifying Epigenetic Biomarkers From Peripheral Blood of Advanced Osteosarcoma Patients, Who Recieve Famitinib and Camrelizumab Based on hMe-Seal Technique
  • Actual Study Start Date: December 2019
  • Estimated Primary Completion Date: June 2021
  • Estimated Study Completion Date: December 2021
Outcome Measures
  • Primary Outcome Measures: 1. 5hmc expression rate [ Time Frame: 24 months ]
  • Biospecimen Retention: Samples With DNA

    cfDNA samples were prepared from peripheral blood collected from patients. Briefly, 8 ml of peripheral blood was collected from each subject using EDTA anticoagulant tubes, and the plasma sample was prepared within 6 h by centrifuging twice at 1 350× g for 12 min, and then centrifuging at 13500× g for 12 min. The prepared plasma samples (about 2 ml/subject) were immediately stored at -80 °C. The plasma cfDNA was isolated using the QIAamp Circulating Nucleic Acid Kit (Qiagen) according to the manufacturer's protocol.

Eligibility Criteria
  • Ages Eligible for Study: 12 Years and older (Child, Adult, Older Adult)
  • Sexes Eligible for Study: All
  • Accepts Healthy Volunteers: No
  • Sampling Method: Non-Probability Sample
  • Study Population: Results of previous study showed high objective response but short-term activity of famitinib in advanced osteosarcoma. Given the recent success of immunotherapies, combinations of antiangiogenics with immune checkpoint blockers have become an attractive strategy. We aimed to investigate the activity of famitinib in combination with camrelizumab in patients with inoperable high-grade osteosarcoma progressing after chemotherapy.
