A Study of AK112 Monotherapy in Advanced/Metastatic Renal Cell Carcinoma

June 19, 2024 updated by: Jun Guo, Peking University Cancer Hospital & Institute

This is an open-label, single arm , Ib/II phase trial to evaluate the efficacy and safety of AK112（ivonescimab）monotherapy as first-line treatment for favourable risk advanced/metastatic renal cell carcinoma (a/m RCC).

Subjects will receive AK112 until disease progression, unacceptable toxic effects, death，a decision by the physician or patient to withdraw from the trial，or AK112 exposure over 2 years.

The study set dose exploration stage and dose expansion stage respectively. Firstly, include a few subjects for observation in dose exploration stage, and select appropriate dose to enter expansion, then continue to include more subjects to further assessment.

  • Has newly diagnosed brain metastases or known symptomatic brain metastases requiring steroids.
  • Had major surgery 4 weeks prior to receiving first dose of trial treatment.
  • Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 14 days prior to receiving first dose of trial treatment.
  • Has an active tuberculosis and syphilitic infection.
  • Has a known history of Human Immunodeficiency Virus (HIV) infection (HIV antibodies).
  • Has known active Hepatitis B (e.g., Hepatitis B surface antigen [HBsAg] reactive and HBV-DNA>2000 IU/ml) or Hepatitis C virus (e.g., HCV RNA [qualitative] is detected).
