Study Using a Genomic Predictor of Platinum Resistance to Guide Therapy in Stage IIIB/IV Non-Small Cell Lung Cancer (TOP0602)

Phase II Prospective Study Evaluating the Role of Personalized Chemotherapy Regimens for Chemo-Naive Select Stage IIIB and IV Non-Small Cell Lung Cancer (NSCLC) in Patients Using a Genomic Predictor of Platinum Resistance to Guide Therapy

In this trial, subjects with chemo-naive advanced non-small cell lung cancer (NSCLC) were assigned to chemotherapy using a genomic-based predictor for platinum sensitivity. After an amendment dated 1/25/2010, subjects with squamous cell NSCLC sensitive to cisplatin received cisplatin/gemcitabine and if resistant to cisplatin received docetaxel/gemcitabine. Subjects with non-squamous cell NSCLC sensitive to cisplatin received cisplatin/pemetrexed and if resistant to cisplatin received pemetrexed/gemcitabine. The primary objective of this trial was to prospectively validate the genomic-based prediction model through separate evaluation of the one-year progression-free survival (PFS) of the cisplatin-sensitive and cisplatin-resistant cohorts. Secondary objectives included: assessment of overall time to progressive disease, quality of life and evaluation of drug sensitivity patterns of cisplatin and pemetrexed.

Study Overview

• Status: Terminated
• Conditions: Non Small Cell Lung Cancer
• Intervention / Treatment: Drug: Cisplatin & Gemcitabine; Drug: Cisplatin & Pemetrexed; Drug: Docetaxel & Gemcitabine; Drug: Pemetrexed & Gemcitabine

Detailed Description

Lung cancer is the leading cause of cancer death in both men and women. The majority of patients with lung cancer have non-small cell type (NSCLC). The current standard of care for treating select stage IIIB and stage IV NSCLC is a doublet chemotherapy regimen, such as cisplatin plus gemcitabine, carboplatin plus paclitaxel, or a platinum agent plus vinorelbine. All of these regimens have comparable response rates as first-line therapy. In addition, the combination of cisplatin plus pemetrexed has recently been approved for non-squamous histology, based on results of a large randomized prospective trial in advanced stage NSCLC. Alternative doublet therapy for first-line treatment of NSCLC per ASCO and NCCN guidelines also include a non-platinum doublet or single agent therapy.

An individual patient's response to chemotherapy is the result of complex interactions between the drug(s) and the patient's genetics and environment. Using Affymetrix gene expression data with corresponding drug response data for cisplatin from the NCI60 lines panel, a gene expression based model predicative of cisplatin-resistant has been developed. However, reevaluation of the genomics-based prediction model showed that it was irreproducible, suggesting inaccurate patient assignments into the two cisplatin cohorts. As a result, it would be inappropriate to separately analyze outcomes for the different treatment groups. Instead, information from both cisplatin cohorts will be combined to reflect the overall measure of one-year progression-free survival in this study. Secondary outcomes will also reflect the overall measures of median time to disease progression and quality of life.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
1-year Progression Free Survival Rate in Chemo-naive Select Stage IIIB or Stage IV NSCLC Patients	One-year progression-free survival was defined from the time from initiation of study treatment to the first date of disease progression or death as a result of any cause. Progression was defined as at least a 20% increase in the sum of the longest diameter (LD) of target lesions taking as references the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. Time was censored at the date of the last follow-up visit for patients who were still alive and have not progressed. The one-year progression free survival rate is a percentage, representing the fraction of treated patients who, after one-year, are disease free or alive.	1 year

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Median Time to Progressive Disease	Median time to progressive disease was defined as the time from enrollment to the the time at which 50% of patients had experienced disease progression. Enrollment is defined as having successful genomic analysis and start of chemotherapy. Time was censored at date of death for patients who have not had documented disease progression, at first available date of other anti-tumor therapy for patients who were either administered other anti-tumor therapy prior to documented disease progression or administered other anti-tumor therapy without documented disease progression, and at last date of followup if neither non-protocol therapy was administered nor progression documented.	1 Year
Mean Change From Baseline to Follow-up Cycle in Quality of Life - Functional Assessment of Cancer Therapy-Lung (FACT-L)	The outcome measure is mean change in the Trial Outcome Index (TOI) between baseline and each follow-up assessment measured by the Functional Assessment of Cancer Therapy-Lung (FACT-L). The FACT-L instrument consists of 34 items to assess physical (PWB), social and family (SWB), emotional (EWB), functional well-being (FWB) and additional lung specific concerns (LCS). Using a 5-point Likert type scale, responses to individual items range from 0 (not at all) to 4 (Very Much) with higher scores indicating better quality of life. The TOI is the sum of PWB (7 items), FWB (7 items) and LCS scores (7 items), which each have a possible range between 0 and 28. Therefore, TOI ranges from 0 to 84.	Baseline, Every 21 days for a maximum of 6 cycles
Drug Sensitivity Quartiles for Cisplatin and Pemetrexed	Using genomics-based prediction models previously developed separately for cisplatin and pemetrexed, the probability that each patient was sensitive or would respond to treatment was computed. Quartiles describe the patterns of drug sensitivity probabilities. The 1st, 2nd, and 3rd quartiles are the sensitivity levels at which 25%, 50%, and 75% of patients have lower sensitivity.	3 years
