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

Overview

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.

Interventions

  • Drug: Anlotinib hydrochloride
    • Anlotinib 12mg per person per day, continuous medication for 2 weeks and 1 week off, 3 weeks 1 cycle, until disease progression or intolerable toxicity
  • Drug: PD-1 inhibitor
    • Intravenous injection, once every 3 weeks, until the disease progression or intolerable toxicity

Arms, Groups and Cohorts

  • Experimental: Anlotinib combined with PD-1 monoclonal antibody
    • Anlotinib, a multi-target tyrosine kinase inhibitor,oral,12mg/10mg/8mg,2 weeks on and 1 week off; PD-1 monoclonal antibody,PD-1 inhibitor,Intravenous injection,once 3 week.
  • Active Comparator: Anlotinib monotherapy
    • Anlotinib, a multi-target tyrosine kinase inhibitor,oral,12mg/10mg/8mg,2 weeks on and 1 week off.
