An Integrated Approach to Treating Recurrent Thoracic Carcinomas Resistant to Tyrosine Kinase Inhibitors

October 15, 2020 updated by: Jin Jen, M.D., Ph.D., Mayo Clinic
Patients are asked to participate in this study if they have been diagnosed with a thoracic carcinoma which includes lung cancer and have a gene mutation (alteration in the body's genetic instructions) and after undergoing treatment the cancer has come back, progressed, or shown a partial response on standard treatment.

Study Overview

Conditions

Detailed Description

In order to improve the treatment outcome for thoracic carcinomas after they become resistant to targeted therapy, the investigator is using tumor biopsies at the time of recurrence for genomic analysis to identify novel somatic changes in critical genes and gene pathways that can potentially be targeted with therapy. The study team is also creating patient-derived xenografts to test drug efficacy and optimize personalized therapy for each patient.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Identify the number of molecular changes in the recurrent tumor through molecular analysis with gene panels.
Time Frame: 1 Year
To determine molecular changes in the recurrent tumor, identify the most significant genes and pathways and clinical phenotypes in lung adenocarcinomas resistant to tyrosine kinase inhibitor treatment.
1 Year
Number of tumorgrafts from biopsies of the recurrent tumor grown and used for drug treatment selection based on genomic signatures.
Time Frame: 1 Year
Mice will be used to grow tumor xenografts. For subsequent passages, tumors will be implanted through passage mice. The patient-derived xenograft-baring mice will then be used for anti-tumor efficacy studies according to the patient prior therapeutic history and molecular signature of the tumor biopsy.
1 Year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Recording turn-around-time
Time Frame: 1 year
Time metrics from biopsy to completion of molecular genetic tests; the time and the success rate of tumorgraft growth in mice as well as the optimal time lapse between initiation treatment to observation of response will be examined. This will aid in the determination of feasibility and opportunities of using patient specific treatment for tumor recurrence.
