Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Unspecified Adult Solid Tumor, Protocol Specific Biological: TR1801-ADC Phase 1

Detailed Description:
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.

Estimated Study Completion Date : March 31, 2023

Arm Intervention/treatment
Experimental: TR1801-ADC
Humanized anti-c-Met monoclonal antibody conjugated to a cleavable pyrrolobenzodiazepine toxin
Biological: TR1801-ADC

Primary Outcome Measures :
  1. Characterize safety of TR1801-ADC in patients with advanced solid tumor malignancies which express c-Met [ Time Frame: 2 years ]
    Number of participants with treatment-related adverse events

  2. Establish maximum tolerated dose [ Time Frame: 1.5 years ]
    Number of participants with protocol-defined dose-limiting toxicity

Secondary Outcome Measures :
  1. Evaluate pharmacokinetics of TR1801-ADC [ Time Frame: 2 years ]
    Analyze blood plasma concentrations

  2. Immunogenicity [ Time Frame: 2 years ]
    Assess anti-drug antibodies of TR1801-ADC

  3. Evaluate clinical activity of TR1801-ADC [ Time Frame: 3 years ]
    Assess objective response rate in accordance with Response Evaluation Criteria in Solid Tumors (RECIST V1.1)
