Study Summary

This is a Phase 1a/1b, open-label, multicenter dose escalation and dose expansion clinical study to evaluate the safety, PK, immunogenicity and preliminary efficacy of IDE034 in participants with locally advanced/metastatic solid tumor types that express B7-H3 and PTK7.

    • Phase
    The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
