Clinical Study on the Prevention of Driver Gene Negative Ib-IIIb Lung Cancer Recurrence and Metastasis by Staged Chinese Herbal Medicine Combined With Chemotherapy and Immune Checkpoint Inhibitors

Shanghai University of Traditional Chinese Medicine367 enrolled

Overview

This project adopts a prospective, multicenter, randomized controlled clinical study to investigate the treatment of TCM in postoperative patients with driver gene negative lung cancer, according to two phases of postoperative adjuvant therapy: (i) chemotherapy phase immunotherapy phase. In this study, 367 patients (183 in the control group and 184 in the trial group) will be observed over 4 years, and the quality of life, toxic effects and safety of this therapy will be investigated. This study will provide evidence-based evidence for the establishment and optimization of a new model of postoperative staged TCM with adjuvant chemo-immunotherapy for lung cancer.

With the discovery of lung cancer driver genes, postoperative adjuvant therapy for lung cancers has been revolutionized. ADJUVANT, EVAN, EVIDNECE and IMPACT, have successively conducted efficacy and safety studies in the field of postoperative adjuvant therapy after generation EGFR-TKI. Adjuvant targeted therapy is also recommended by guidelines based on the significant improvement of DFS in mutation-positive patients. Unfortunately, 55% of NSCLC patients are driver gene-negative. Research in postoperative mutation-negative patients is relatively lagging behind. Chemotherapy remains the treatment of choice at this time. How to delay recurrence of metastasis in this population needs further study. Studies have shown that 1 year of adjuvant atezolizumab after chemotherapy in postoperative driver gene-negative patients significantly prolongs median DFS. For any PD-L1-expressing stage II-IIIa patients, adjuvant atezolizumab therapy has a median DFS of 42.3 months. Atezolizumab is recommended in the NCCN 2021 edition of clinical guidelines for patients with stage IIb-IIIa TPS ≥ 1%. In recent years, there has been great progress in the study of combined adjuvant therapy of Chinese medicine after lung cancer surgery. At present, research on TCM in the field of postoperative lung cancer is mainly focused on combined chemotherapy, which can reduce the occurrence of adverse events, improve quality of life, prevent recurrence and metastasis, and increase survival rate. More and higher-grade clinical evidence is needed to explore and validate the combination of TCM with immunotherapy. Using a multicenter, randomized, double-blind, controlled prospective study, 367 patients with stage Ib-IIIb driver gene-negative NSCLC after undergoing radical surgery will be randomly divided into experimental and control groups, and postoperative adjuvant therapy will be administered in two phases: (i) chemotherapy phase: observation group (chemotherapy + TCM 1), control group (chemotherapy + TCM 1 placebo); (ii) immunization phase: observation group (ICIs + TCM2), control group (ICIs + TCM2 placebo). Treatment cycles will be 4 cycles of chemotherapy and 12 cycles of immunotherapy, and the indication for discontinuation will be the end of treatment or the patient's intolerance of treatment. Patients will be followed up regularly thereafter. The primary efficacy assessments are: disease-free survival (DFS); secondary efficacy assessments are: (1) quality of life: EORTC QLQ-LC43(V 4.0) scale; (2) changes in clinical signs of TCM; (3) biological indicators: ctDNA-MRD, peripheral blood immune factor series, plasma exosomal PD-L1; (4) overall survival (OS). An assessment of the toxic side effects and safety of the treatment regimen is also made by using CTC AE (V5.0). This regimen is expected to prolong disease-free survival and reduce toxic side effects. The study will provide evidence to optimize and promote the protocol of postoperative TCM combined with immunotherapy for lung cancer.

Interventions

In China,TCM herbs are given on the basis of the TCM syndrome differentiation as diagnosed by the TCM herbal specialist. Prescriptions formulated into granules origin from Professor Liu Jia-xiang and Xu Ling. Package of granules is made into two types with functions such as tonifying the stomach and nourishing the blood recipe, benefiting Qi Yin and detoxification and resolving masses recipe. The herbal treatment is adapted to the syndromes. Chemotherapy：Vincristine/paclitaxel/docetaxel/pemetrexed/gemcitabine plus cisplatin/carboplatin：administrated for patients with NSCLC requiring post-operative adjuvant therapy.
