TR1801-ADC in Patients With Tumors That Express c-Met

A Phase 1, Open Label, First-in-human Study of TR1801-ADC, an Antibody Drug Conjugate (ADC), in Patients With Select Solid Tumors Expressing c-Met

First-in-human, Phase 1 study to assess safety, tolerability, and pharmacokinetics of TR1801-ADC in patients with select solid tumors that express c-Met.

First-in-human, Phase 1, multiple dose-dose escalation study designed to determine safety, tolerability, maximum tolerated dose, and recommended phase 2 dose of TR1801-ADC in patients with select solid tumors that express c-Met. This study will also assess pharmacokinetics (PK), anti-tumor activity, and correlation between clinical outcomes (safety, anti-tumor activity, and PK) and c-Met expression.
