NCT05830123

Brief Summary

HS-20093 is a fully humanized IgG1 antibody-drug conjugate (ADC) which specifically binds to B7-H3, a target wildly expressed on solid tumor cells. This is a phase 2, open-label, multi-center study to evaluate the efficacy, safety, pharmacokinetics (PK) and immunogenicity of HS-20093 as a monotherapy in patients with relapsed or refractory osteosarcoma and other sarcomas.

Outcome Measures

Primary Outcomes (1)

  • Objective response rate (ORR) determined by investigators according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1

    ORR was defined as the percentage of participants who achieved a best overall response (BOR) of confirmed Complete Response (CR) or Partial Response (PR), assessed by investigators based on RECIST version 1.1\[Confirmed CR/PR assessment require at least one repeat (≥4 weeks)\].

    From the first dose up to disease progression or withdrawal from study, whichever came first, assessed up to 24 months.

Secondary Outcomes (12)

  • Incidence and severity of adverse events (AEs)

    From the first dose through 90 days post end of treatment.

  • Observed maximum plasma concentration (Cmax) of HS-20093

    From pre-dose to 14 days after the first dose on Cycle 1 (each cycle is 21 days)

  • Time to reach maximum plasma concentration (Tmax) of HS-20093 following the first dose

    From pre-dose to 14 days after the first dose on Cycle 1 (each cycle is 21 days)

  • Terminal half-life (T1/2) of HS-20093 following the first dose

    From pre-dose to 14 days after the first dose on Cycle 1 (each cycle is 21 days)

  • Area under plasma concentration versus time curve from zero to last sampling time (AUC0-t) following the first dose of HS-20093

    From pre-dose to 14 days after the first dose on Cycle 1 (each cycle is 21 days)

  • +7 more secondary outcomes
