Personalized Therapy in Non-small Cell Lung Cancer (PTINCLC)

December 15, 2014 updated by: Heyuwen, Guangzhou Medical University

The Clinical Study of Personalized Therapy for Non-small Cell Lung Cancer Based on ERCC1/RRM1/TS Expression

Excision repair cross complementing 1 (ERCC1) ribonucleotide reductase M1 (RRM1) and thymidylate synthase(TS) are molecular determinants that predict sensitivity or resistance to platinum agents 、 gemcitabine and pemetrexed respectively.

Tailored therapy using these molecular determinants suggested patient benefit in a previously reported phase 2 trial. Here, we designed a study for an individual patient analysis of prospectively accrued patients who were treated with the "personalized therapy" approach versus other standard approaches.

Study Overview

Detailed Description

Patients who had nonsmall- cell lung cancer (NSCLC) performance status of 0/1 were accrued to 2 phase 2 clinical trials Trial A (carboplatin and chemotherapy individuation based on sensitivity marker ), Trial B (carboplatin non-individuation or chemotherapy non-individuation ).

Patients who were treated on Trials B were analyzed as the "standard therapy" group. Patients accrued to Trial A were called the "personalized therapy" group. disease free survival (DFS) was estimated using the Kaplan-Meier method.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: A.individual therapy
Carboplatin was administrated at an area under the plasma concentration time curve (AUC) of 5 on day 1 every 21 days, while gemcitabine was administrated at a dose of 1250 mg/m2 on day 1 and 8 and pemetrexed was administrated at a dose of 500 mg/m2 on day 1.

A.individual therapy :enrolled patients with ERCC1 negative tumors who received carboplatin and a third-generation agent (gemcitabine or pametrexed) based on RRM1 or TS expression. If RRM1 protein was negatively expressed in the tumor tissues, gemcitabine was used, whereas pemetrexed was used if RRM1 was positively expressed and TS was negatively expressed.

B.non-individualized therapy :enrolled patients who received carboplatin and a third-generation agent but were not based on ERCC1, RRM1, or TS expression.
