NCT06545331

Brief Summary

This is a FIH study is to evaluate the safety, tolerability, PK, immunogenicity, and preliminary antitumor activity of XB010 as a single agent and in combination with pembrolizumab in subjects with locally advanced or metastatic solid tumors for whom alternative therapies do not exist or available therapies are intolerable or no longer effective.

Outcome Measures

Primary Outcomes (5)

  • Dose-Escalation Stage: Maximum tolerated dose (MTD) and/or Recommended dose(s) for Expansion [RDE(s)] for XB010

    To determine the MTD and/or RDE(s) for further evaluation of IV administration of XB010 alone and in combination therapy.

    18 months

  • Dose-Escalation Stage: Safety of XB010

    To evaluate the safety of XB010 alone and in combination therapy through the evaluation of incidence and severity of nonserious adverse events (AEs) and serious adverse events (SAEs)

    18 months

  • Dose-Escalation Stage: Duration of exposure of XB010 [Tolerability]

    To evaluate the tolerability of XB010 alone and in combination therapy through the evaluation of the duration of exposure of each component

    18 months

  • Dose-Escalation Stage: Dose intensity of XB010 [Tolerability]

    To evaluate the tolerability of XB010 alone and in combination therapy through the evaluation of the dose intensity of each component

    18 months

  • Cohort-Expansion Stage: Preliminary antitumor activity of XB010

    Objective Response Rate (ORR) as assessed by the Investigator per RECIST 1.1

    24 months

Secondary Outcomes (14)

  • Dose-Escalation Stage: Clearance of XB010

    18 Months

  • Dose-Escalation Stage: Area Under the Plasma Concentration Curve (AUC) of XB010

    18 Months

  • Dose-Escalation Stage: Minimum Plasma Concentration (Cmin) of XB010

    18 Months

  • +9 more secondary outcomes
