Non-small Cell Lung Cancer Clinical Trial

Official title: Overcoming Resistance to Immunotherapy Combining Gemcitabine With Atezolizumab in Advanced NSCLC and Mesothelioma Progressing Under Immune-checkpoint Inhibitors or Gemcitabine. A Multicenter, Single-arm, Open Label Phase II Trial With Two Cohorts

Status Active, not recruiting

Clinical Trial Summary

A significant number of patients with malignant pleural mesothelioma (MPM) and non-small cell lung cancer (NSCLC) are not cured with available treatments and will eventually relapse. After relapse treatment options are limited. Preclinical in vitro studies have demonstrated a synergism of immunotherapy with PD(L)1-targeting monoclonal antibodies and gemcitabine and ongoing clinical studies showed encouraging results. The main objective of this trial is to determine the efficacy of chemotherapy (gemcitabine) combined with immunotherapy (atezolizumab) in patients with progressive NSCLC and MPM. The trial treatments will be continued for max. 2 years or until discontinuation criteria are met. The follow-up phase will last up to 5 years from treatment start.

Clinical Trial Description

The trial combines two (Gemcitabine and Atezolizumab). Gemcitabine, alone or in combination regimens is a standard of care for several solid tumors, such as advanced or metastatic NSCLC. It is also used in an off-label setting for pre-treated MPM or naïve MPM in combination with platin-chemotherapy. Atezolizumab is approved in the United States, European Union and in Switzerland for the treatment of NSCLC, urothelial carcinoma, small cell lung cancer (SCLC), triple-negative breast cancer (TNBC) and hepatocellular carcinoma (HCC) patients. A significant number of patients with malignant pleural mesothelioma (MPM) and non-small cell lung cancer (NSCLC) are not cured with available treatments and will eventually relapse. After relapse treatment options are limited. Preclinical in vitro studies have demonstrated a synergism of immunotherapy with PD(L)1-targeting monoclonal antibodies and gemcitabine administered in different tumors models and ongoing clinical studies showed encouraging results. This may represent a safe and effective therapy for patients who relapsed or did not respond to standard therapies. Patients will be treated with gemcitabine (1000 mg/m2 i.v. on day 1 and day 8 of each cycle, (every 3 weeks) and with atezolizumab (1200 mg i.v. on day 1 of each cycle, (every 3 weeks). The trial treatments will be continued for max. 2 years or until discontinuation criteria are met. The follow-up phase will last up to 5 years from treatment start. The main objective of this trial is to determine the efficacy of chemotherapy (gemcitabine) combined with immunotherapy (atezolizumab) in patients with progressive NSCLC and MPM. ;
