Clinical Study of YYJD Decoction Combined With Gefitinib in Advanced Pulmonary Adenocarcinoma
- Registration Number
- NCT02929693
- Lead Sponsor
- Shanghai University of Traditional Chinese Medicine
- Brief Summary
The investigators performed a multi-centered, randomized, double blinded, placebo-controlled, prospective clinical trial on the effect of Yiqi-yangyin-jiedu decoction (YYJD), a chinese herbal medicine (CHM) formula combined with gefitinib to prolong the progression free survival (PFS) of advanced pulmonary adenocarcinoma patients with activating EGFR mutation (exon19del or exon21L858R). The investigators plan to enroll 198 cases in 3 years (99 cases for gefitinib, 99 cases for gefitinib plus YYJD), expecting that combination therapy has a better efficacy on prolonging PFS, overall survival, improving quality of life(QOL).
- Detailed Description
Non-Small-Cell Lung Cancer（NSCLC）is one of the malignancies with high incidence and mortality. Epidermal growth factor receptor (EGFR) is implicated in NSCLC pathogenesis. Certain patient subgroups with NSCLC (ie, women, never-smokers, East Asians,adenocarcinoma) have higher rates of EGFR mutations, rendering them more responsive to EGFR tyrosine kinase inhibitors (TKIs; eg, gefitinib, erlotinib, Icotinib). Among patients with advanced EGFR-mutated NSCLC, treatment with EGFR-TKIs is associated with response rates of 56 to 74% and a median progression-free survival(mPFS) of 10 to 14 months;both outcomes are superior to those with platinum-based chemotherapy. Despite initial responses to EGFR-TKIs, the majority of patients will have disease progression within 1 to 2 years after treatment initiation (acquired resistance). In approximately 60% of patients, the mechanism of acquired resistance is the development of an additional EGFR mutation, EGFR T790M. Although AZD9291 (AstraZeneca), a third-generation EGFR-TKI is reported with a response rate of 61% in NSCLC patients with EGFR T790M and a mPFS of 9.6 months, resistance to third-generation inhibitors mediated by EGFR C797S mutation is inevitable. Therefore, optimizing the effect of each generation of EGFR-TKI is essential for long-term survival of NSCLC.The investigators' preliminary studies have shown that combining Yiqi-yangyin-jiedu decoction (YYJD) with gefitinib can prolong PFS and improve QOL, but high-level evidences are needed.
The investigators performed a multi-centered, randomized, double blinded, placebo-controlled, prospective clinical trial on the effect of YYJD, a chinese herbal medicine (CHM) formula combined with gefitinib in advanced pulmonary adenocarcinoma patients with activating EGFR mutation (exon19del or exon21L858R) that choose gefitinib as first-line or second line therapy. Patients are randomized into observational group (YYJD plus gefitinib),and control group (placebo plus gefitinib). The treatment should be continued until evidence of disease progression or unacceptable toxicity, and after that regular follow-up will be arranged. The primary efficacy assessments are: PFS (progression-free survival); Secondary efficacy assessments are: (1) OS (overall survival); (2) Objective response rate; (3) QOL (Functional Assessment of Cancer therapy-lung, FACT-L4.0 scales; Lung Cancer Symptom Scale, LCSS); (4) other efficacy assessments are: 1) TCM symptoms changes; 2) Toxicity, side effects and security of the treatments will be assessed at the same time. The investigators plan to enroll 198 cases in 3 years (99 cases for gefitinib, 99 cases for gefitinib plus YYJD), expecting that combination therapy has a better efficacy on prolonging PFS, overall survival, improving quality of life(QOL). Therefore the study can provide evidences for optimizing and promoting the efficacy of gefitinib.

- Primary Outcome Measures
Name Time Method Progression-free survival (PFS) 2 months Time from start of the study treatment to date of objective tumour progression (excluding clinical deterioration without evidence of objective progression).
- Secondary Outcome Measures
Name Time Method Overall survival (OS) 2 months interval time from the first date of randomization to that of death for any reason, the end of the study, or loss of follow-up
Quality of life (QOL) 2 months QOL is assessed using Functional Assessment of Cancer therapy-lung (FACT-L) questionnaire .
Objective response rate (ORR) 2 months The ORR (complete response (CR) plus partial response (PR)) was determined by the Response Evaluation Criteria In Solid Tumors (RECIST) (Eisenhauer et al, 2009) version 1.1.in Solid Tumors (RECIST1.1).
Safety assessment evaluated according to Common Toxicity Criteria 2 months Safety assessment is evaluated according to Common Toxicity Criteria (CTC 3.0).
