Active clinical trials for "Carcinoma, Non-Small-Cell Lung"

Platinum-based doublets including paclitaxel, gemcitabine, or docetaxel are standard 1st regimens in Non-Small Cell Lung Cancer(NSCLC). The traditional method of individualizing cytotoxic drug dose is by using body surface area(BSA), which is not correlated with the ability of an individual to metabolize or excrete cytotoxic drugs, because it is not related to liver function and is poorly correlated with glomerular filtration rate, and does not seem to be a determinant of toxicity. Pharmacokinetic parameters such as area under the curve have been shown to correlate with toxicity. The advantages of using a fixed dose of antineoplastic agents for all of the patients are obvious. Pharmacokinetically guided treatment would avoid severe adverse effects, which has not been sufficiently investigated in advanced NSCLC.First, the investigators monitor the blood concentrations of paclitaxel and neutropenia blood toxicity after chemotherapy with paclitaxel and carboplatin in patients of NSCLC and verify suitable paclitaxel therapeutic window for Chinese patients. Then the investigators compare safety and efficacy between individual paclitaxel dose adjustment based on the therapeutic window compared with conventional dosage.

The purpose of this study is to determine whether Icotinib is efficient and safe in treating advanced non-small cell lung cancer (NSCLC) patients with hepatic insufficiency.

ROS1 is a receptor tyrosine kinase with constitutive kinase activity. ROS1 was previously discovered in cell lines where ROS1 fused with other proteins to act as a driver oncogene. In 2007, Rikova et al reported ROS1 fusion as driver mutations in NSCLC cell line (HCC78; SLC34A2-ROS1) and NSCLC patient (CD74-ROS1). Li et al also found about 1% of samples harboring CD74-ROS1 fusion in 202 resected lung adenocarcinomas from never smokers. The incidence was as high as 10% in East Asian population. Currently there are now at least 13 ROS1 fusion variants involving 8 fusion partners (CD74-, SLC34A2-, FIG-, TPM3-, SDC4-, LRIG3-, ERZ-, KDERL2-) identified in ROS1 positive NSCLC. LDK378 is an orally highly selective and potent ALK kinase inhibitor. In preclinical studies, LDK378 has much lower IC50 values than crizotinib in cell lines engineered to express ROS1 rearrangement (0.15 nM versus 3 nM) and is approximately 20-fold more potent. LDK378 is a potent inhibitor of tumor growth in rodent models of both ALCL and NSCLC. We suggest a phase II trial of LDK378 in advanced non-small cell lung cancer patients with ROS1 rearrangement. The aim of current trial is to evaluate the antitumor efficacy and safety profile of LDK378 and to identify biomarker to predict the tumor response to LDK378.

EGFR-tyrosine kinase inhibitor(TKI)- ie, erlotinib, gefitinib, has been recommended as the first option for EGFR-mutated IIIb/IV NSCLC by serial trials as it prolonged patients' progression-free survival. The OPTIMAl trial indicated that those who received TKI and chemotherapy during the whole treatment window survived longest. Unfortunately, previous studies(INTACT, TRIBUTE et al) that concurrently combined TKI and cytotoxic regimens failed to improve survival in unselected patients. To avoid the potential synergistic antagonism, the FAST-ACT II trial committed a sequential strategy and find a superiority in the combination arm upon chemotherapy even in EGFR-mutated group. However, pharmaceutically, the continuous administration of an EGFR-TKI before subsequent chemotherapy in FAST-ACT II could obviate the effects of cytotoxic agents due to the erlotinib-induced G1 arrest. On the basis of these and other studies, the investigators hypothesized that a better sequential combination strategy of EGFR-TKI and chemotherapy (adding a EGFR-TKI wash-out window before chemotherapy) would be more efficacious than chemotherapy alone. In this study, the investigators investigate the efficacy(PFS:progression free survival), safety, and adverse-event profile of chemotherapy plus intermittent and maintenance of erlotinib, when these drugs were used as first-line treatment in who had non-squamous lung carcinoma with EGFR gene mutation in China.

We hypothesize that higher dose icotinib is related with better efficacy. The primary objective is to compare the progression-free survival of higher dose and routine dose of icotinib in treating pretreated advanced non-small cell lung cancer patients with stable disease after 8-week routine dose icotinib treatment.

platinum-based albumin-bound paclitaxel regimen in advanced non-small cell lung cancer (NSCLC) especially in lung squamous cell carcinoma has a better tumor response rate and safety than solvent-based paclitaxel.However, the safety and efficacy is uncertain in neoadjuvant therapy.

PFS

As cytotoxic agents, DTX and PTX have a narrow therapeutic window. BSA dosing leads to great inter-individual PK variability, which is a major contributor for severe toxicity, especially in East-Asian populations. DTX exposures measured by area under plasma concentration-time curve (AUC), PTX exposures measured by the time above a plasma concentration of 0.05 µmol/L (TC>0.05), are the most biologic effects associated PK parameters for DTX and PTX, respectively, which could positively predict related toxicities such as neutropenia, peripheral neuropathy, etc. So, we conducted a randomized clinical trial to compare the effect on related toxicities and efficacy of PK-guided dosing strategy and BSA dosing strategy.

This study is a multicenter, randomized, open-label Phase II trial that compares reduced dose erlotinib 100mg daily and standard dose gefitinib 250mg daily in patients with advanced non-small cell lung cancer who harbor EGFR mutations. The primary endpoint is disease control rate (DCR) and the key secondary endpoint is progression free survival (PFS). A total of 224 eligible patients will be randomized to receive either erlotinib 100mg daily or gefitinib 250mg daily in a 1:1 ratio until patients experience disease progression. Independent assessment of the major endpoints will be completed in a treatment-blinded manner. Randomization will be stratified based on treatment-lines (first-line vs. maintenance vs. second-line therapy). Tumor response and progression will be assessed according to RECIST 1.1.

The investigators hypothesized that the Neoadjuvant Chemoradiotherapy was a beneficial treatment for Patients with Stage IIIA-N2 Non-Small Cell Lung Cancer, so we try to evaluate the security of treatment, the QoL of patients and the influence to the PFS and OS.
