      P1.10-056 - The Elderly Patient Individualized Chemotherapy Trial (EPIC): A Randomized Phase III Multicenter Trial of Customized Chemotherapy versus Standard of Care for 1st Line Treatment of Elderly Patients with Advanced Non-Small-Cell Lung Cancer (ID 1117)

      • Abstract

      Background
      This is an ongoing phase III multicenter randomized trial comparing first line pharmacogenomic-driven chemotherapy based on Excision-Repair-Cross-Complementing-1 (ERCC1), Ribonucleotide Reductase subunit M1 (RRM1) and Thymidylate Synthase (TS) gene expression, versus standard first line treatment in elderly patients (pts) with advanced non-small-cell lung cancer (NSCLC). Chemotherapy selection based on an individual patient’s molecular profile is a potentially promising approach to optimize efficacy with the already available cytotoxic drugs. In older pts this is particularly relevant owing to their rapid deterioration of symptoms and their increased propensity to suffer therapy-induced toxicity.

      Methods
      Pts aged >70 years, with ECOG Performance Status (PS) 0 or 1, previously untreated for stage IV NSCLC will be evaluated. In a 2:1 fashion, pts will be randomized to experimental arm (A) or standard arm (B). They must have measurable disease and EGFR negative mutational status. In arm A, treatment with single or dual-agent chemotherapy will be based on histology, ERCC1 (E), RRM1 (R) and TS (T) expression at the mRNA level. Expression of E, R and T is assessed by qRT-PCR on paraffin-embedded tumor specimens in a central laboratory. The cut off for high or low expression have been previously defined. Pts with squamous NSCLC who are: E low/R high will be treated with single agent carboplatin, E high/R low with single agent gemcitabine, E low/R low with carboplatin and gemcitabine and E high/R high with docetaxel or vinorelbine. In non-squamous NSCLC pts: E low/T high will be treated with carboplatin, E high/T low with pemetrexed, E low/T low with carboplatin and pemetrexed, E high/T high/R low with gemcitabine and E high/T high/R high with docetaxel or vinorelbine. In arm B treatment will be standard of care at the discretion of the care provider. The primary endpoint is overall survival (OS). The secondary endpoints are progression-free survival (PFS), disease response according to RECIST 1.1 and tolerability (using CTCAE version 4.0). Feasibility of treatment selection based on pharmacogenomic parameters will also be assessed. Treatment will continue to a maximum of 6 cycles if tolerated or until disease progression. Switch maintenance treatment is not allowed in either arm. Continuation maintenance (one or more of the agents used in the initial regimen) is allowed at the discretion of the investigator. Treatment upon progression is at the discretion of the care provider. Assuming an exponential survival distribution for both treatment arms and a median survival time of 8 months in the control arm we anticipate to detect an improvement of 3 months in the median survival time in the experimental arm. To have 90% power to detect a three-month improvement in median survival at a significance level of 5% (2-sided) and assuming a 10% failure rate in gene analyses or loss to follow up rate, a sample size of 567 patients is planned to be enrolled.

      Conclusion
      We hypothesize that such tailored approach will improve survival decreasing the exposure to ineffective toxic agents in advanced NSCLC elderly pts. To our knowledge this is the first pharmacogenomic-driven randomized trial in this population.

      P3.12-023 - International Tailored Chemotherapy Adjuvant Trial: ITACA Trial (ID 1452)

      09:30 - 09:30  |  Author(s): I. Colantonio

      • Abstract

      Background
      This is an ongoing phase III multicenter randomized trial comparing adjuvant pharmacogenomic-driven chemotherapy, based on thymidilate synthase (TS) and excision-repair cross-complementing-1 (ERCC1) gene expression versus standard adjuvant chemotherapy in completely resected Stage II-IIIA non-small cell lung cancer (EudraCT #: 2008-001764-36).

      Methods
      For all the registered patients (pts) the expression of ERCC1 and TS is assessed by qRT-PCR on paraffin-embedded tumor specimens in a central laboratory. Randomization is stratified by stage and smoking status. Trial was emended on Feb, 2011 with the 7th staging system. Primary end point is overall survival; secondary end points include recurrence-free survival, therapeutic compliance, toxicity profile and comparative evaluation of ERCC1 and TS mRNA versus protein expression. It is assumed that the 5-year survival rate in the control arm is 45% and the hazard reduction associated to the experimental treatment is 30%. With a power of 90% to detect the estimated effect with log-rank test, a significant level of 5% (2 tails), 336 events have to be observed; the expected total number of pts is 700. The final statistical analysis will compare all pts in the control arms versus all those treated in the tailored chemotherapies groups. Efficacy analysis will be done on an intent-to-treat basis. Cox proportional hazard model will be used for estimating hazard ratios after adjusting for relevant variables. Within 45 days post-surgery, pts in each genetic profile are randomized to receive either a standard chemotherapy selected by the investigator (cisplatin/vinorelbine, cisplatin/docetaxel or cisplatin/gemcitabine) or an experimental treatment (tailored arms) selected as follows: 1) high ERCC1 and high TS 4 cycles of single agent paclitaxel 2) high ERCC1 and low TS 4 cycles of single agent pemetrexed 3) low ERCC1 and high TS 4 cycles of cisplatin/gemcitabine 4) low ERCC1 and low TS 4 cycles of cisplatin/pemetrexed. All chemotherapy regimens are administered for a total of 4 cycles on a 3-weekly basis.

      Not applicable

      Conclusion
      Currently, 558 pts have been randomized from 26 institutions mainly located in Italy and Germany (average enrolment: 19 patients/month). This is one of the pharmacogenomic-driven trial in the adjuvant setting in the European scenario.
