Purpose

This is a phase 2 study of AMG 337 in subjects with advanced or metastatic solid tumors that overexpress MET or harbor METex14del mutations resulting in MET exon 14 skipping.

Detailed Description

      This is a phase 2, two-cohort, single-arm open-label study that will assess the efficacy of
      AMG 337 based on ORR in subjects with advanced or metastatic solid tumors that overexpress
      MET or harbor METex14del mutations resulting in MET exon 14 skipping. MET overexpression will
      be determined by quantitative proteomics with mass spectrometry. METex14del mutations
      resulting in MET exon 14 skipping will be determined by DNA sequencing and confirmed with RNA
      sequencing. Subjects will be enrolled as follows:

        -  Cohort 1: Subjects with advanced or metastatic solid tumors that overexpress MET

        -  Cohort 2: Subjects with advanced or metastatic solid tumors that harbor METex14del
           mutations Simon's two-stage optimal design will be utilized separately for each cohort
           to assess the primary efficacy endpoint ORR. The null hypothesis of Simon's two-stage
           design states that the ORR will be ≤ 10% (poor response) and will be tested against a
           one-sided alternative.

Eligibility Criteria

        Inclusion Criteria:

          1. Able to understand and provide a signed informed consent that fulfills the relevant
             Institutional Review Board (IRB) or Independent Ethics Committee (IEC) guidelines.

          4. Age ≥ 16 years old.

          5. Histologically confirmed, unresectable locally advanced or metastatic solid tumor that
             overexpresses tumor MET (determined by quantitative proteomics with mass spectrometry
             [cohort 1]) or harbor METex14del mutations resulting in MET exon 14 skipping (as
             determined by DNA sequencing and confirmed with RNA sequencing [cohort 2]).
