Brief summary: It is a phase II open label, multicenter study to assess the safety, tolerability, pharmacokinetics, and efficacy of HB0025 in patients with advanced clear cell renal cell carcinoma (ccRCC).

Detailed description: The phase II study will enroll subjects with advanced clear cell renal cell carcinoma (ccRCC) who have progressing tumor after standard therapy and have no better treatment option.This study will set up 2 dose groups.HB0025 injection is administered once every 2 weeks.

Patients with childhood asthma or atopy that has not been active in the 2 years prior to study screening are eligible.
