Strata EXPress™: A Study Using StrataEXP™ to Identify RNA-Expression Biomarkers in Advanced Cancer Patients

Withdrawn

• Conditions: Cancer

• Registration Number: NCT05312307
• Lead Sponsor: Strata Oncology

Brief Summary

The primary goal of this study is to identify patients with RNA expression profiles consistent with eligibility requirements for therapeutic clinical trials across solid tumors. Left-over tumor tissue will be collected from eligible participants for RNA expression analysis using next-generation sequencing.

Detailed Description

The primary goal of this study is to identify patients with RNA expression profiles consistent with eligibility requirements for therapeutic clinical trials across solid tumors. Left-over tumor tissue will be collected from eligible participants for RNA expression analysis using next-generation sequencing.

A parallel study, StrataPATH™ (STR-004-001), has been developed to support therapeutic hypotheses. Participants may be consented and screened for enrollment separately into StrataPATH with an eligible matching biomarker/drug treatment cohort upon positive identification of a relevant expression signature. Treatment effectiveness of antibody drug conjugates and other targeted therapies will be evaluated in these molecularly defined cohorts.

Inclusion Criteria

1. Must be ≥18 years of age,

2. Participant must have pathologically confirmed advanced, metastatic, or recurrent solid tumor,

3. Measurable disease,

4. Eastern Cooperative Oncology Group (ECOG) performance status score of 0-2,

5. Participant must meet at least 1 of the following:

   1. Is/has not adequately responded to standard therapy, or
   2. For whom no life-extending standard therapy exists, or
   3. Who decline standard therapy, or
