Brief Title

A Study of Anlotinib Combined With or Without PD-1 Antibody on Unresectable High-grade Chondrosarcoma

Official Title

A Multicenter Clinical Controlled Study of Anlotinib Combined With PD-1 Antibody on Unresectable High-grade Chondrosarcoma With Different IDH Genotypes

Brief Summary

      There is no standard treatment for chondrosarcoma. Some small sample of studies has shown
      that anti-angiogenic TKIs show certain activity in the treatment of chondrosarcoma. PD-1
      inhibitors, in recent years, have also been used in clinical practice and showed good
      efficacy. We intend to explore the response of chondrosarcoma to PD-1 monoclonal antibody and
      the influence of different IDH genotypes on PD-1 monoclonal antibody response.

Detailed Description

      We intend to explore the response of chondrosarcoma to PD-1 monoclonal antibody and the
      influence of different IDH genotypes on PD-1 monoclonal antibody response. Patients with
      unresectable locally advanced or metastatic chondrosarcomas(CS), including high-grade
      (II-III) ordinary CS and dedifferentiated CS, are qualified. The experimental group was PD-1
      monoclonal antibody combined with Anlotinib for treatment of unresectable locally advanced or
      metastatic CS, and the control group was anlotinib monotherapy. The treatment is continuous
      until the disease progression or intolerable toxicity. CS with disease progression in the
      control group was allowed to enter the experimental group to continue treatment. The primary
      endpoint was 6-month PFSR.
