“The targeted therapy gefitinib appears more effective in preventing recurrence after lung cancer surgery than the standard of care, chemotherapy. In a phase III clinical trial, patients with epidermal growth factor receptor (EGFR)-positive, stage II-IIIA non-small cell lung cancer (NSCLC) who received gefitinib went about 10 months longer without recurrence than patients who received chemotherapy. The study will be presented at the upcoming 2017 ASCO Annual Meeting in Chicago.
” ‘Adjuvant gefitinib may ultimately be considered as an important option for stage II-IIIA lung cancer patients with an active EGFR mutation, and we may consider routine EGFR testing in this earlier stage of lung cancer,’ said lead study author Yi-Long Wu, MD, a director of the Guangdong Lung Cancer Institute, Guangdong General Hospital, Guangzhou, China. ‘We intend to follow these patients until we can fully measure overall survival as opposed to disease-free survival, which just measures disease recurrence.’ ”
“Osimertinib improves cancer-related symptoms in patients with advanced lung cancer, according to an analysis of patient-reported outcomes from the AURA3 phase III clinical trial presented at the European Lung Cancer Conference (ELCC).
” ‘With my past experience conducting clinical trials, I often see new treatments that might be more effective, but are also usually more toxic,’ said lead author Dr Chee Lee, Medical Oncologist, St George Hospital Cancer Care Centre, New South Wales, Australia. ‘Osimertinib not only increases progression-free survival but it is well-tolerated, which makes a big difference for our patients.’ ”
“The China Food and Drug Administration (CFDA) has approved osimertinib for the treatment of patients with locally-advanced or metastatic EGFR T790M-positive non–small cell lung cancer (NSCLC) with progression following treatment with an EGFR tyrosine kinase inhibitor (TKI).
“Osimertinib was approved under the CFDA’s accelerated Priority Review Pathway. To receive the treatment, patients must have their EGFR T790M mutation status confirmed through a validated test.”
“About 10 percent of lung cancers in the United States and as many as 40 percent in Asia are driven by mutations in the EGFR gene. EGFR targeted treatment advances over the previous decade now result in multiple options for controlling the disease in the body, but due to the reduced ability of many of these drugs to penetrate into the brain, treating of disease in the brain remains challenging. When brain metastases are seen at diagnosis before a patient has tried EGFR-targeted drugs, it has been an open question whether doctors should try drugs alone just in case they work in the brain or move directly to whole-brain radiotherapy or stereotactic radiosurgery (a tightly focused form of radiation) first, followed by targeted medicines. A study published in the Journal of Clinical Oncology looks back at 351 patients with EGFR mutant lung cancer and brain metastases treated at six institutions to offer compelling preliminary evidence as to the best sequence of these techniques: Radiation followed by targeted medicines resulted in the longest overall survival.”
“Genprex, Inc. today announced positive interim data from an ongoing Phase II clinical trial (NCT01455389) evaluating its investigational immunogene therapy candidate Oncoprex™ in combination with the tyrosine kinase inhibitor (TKI) erlotinib (Tarceva®) for the treatment of late stage non-small cell lung cancer (NSCLC) patients.”
“Treatment with icotinib more than doubled intracranial progression-free survival (iPFS) compared with whole brain irradiation (WBI) combined with standard chemotherapy, according to phase III trial results presented at the 17th World Lung Cancer Conference, the Annual Meeting of the International Association for the Study of Lung Cancer (IASLC), in Vienna.
“Icotinib significantly improved median iPFS, the trial’s primary endpoint, to 10.0 months compared with 4.8 months in patients treated with WBI and chemotherapy, HR = 0.56; 95% CI, 0.36-0.90 (P = .014). Secondary endpoints of the trial, including progression-free survival (PFS) and the objective response rate (ORR), were also significantly improved with icotinib over WBI/chemotherapy. Median PFS was 6.8 versus 3.4 months, respectively (HR, 0.44; 95% CI, 0.31-0.63 [P < .001]).”
“AstraZeneca today presented data from the AURA3 trial that data is supportive of Tagrisso (osimertinib) potentially becoming the new standard of care for 2nd-line treatment of patients with epidermal growth factor receptor (EGFR) T790M mutation-positive locally-advanced or metastatic non-small cell lung cancer (NSCLC). The first randomised Phase III data showed that Tagrisso 2nd-line therapy improved progression-free survival (PFS) by 5.7 months compared with standard platinum-based doublet chemotherapy (Hazard Ratio [HR]=0.3). The results were presented at the 17th World Conference on Lung Cancer (WCLC) in Vienna, Austria, hosted by the International Association for the Study of Lung Cancer, and published simultaneously online in The New England Journal of Medicine.”
“Phase 1 study results presented at the 21st Annual Scientific Meeting and Education Day of the Society for Neuro-Oncology (SNO) demonstrated the antibody drug conjugate ABT-414 has shown promising results for the treatment of patients with EGFR-amplified, recurrent glioblastoma (GBM).
“Lead author Martin van den Bent, MD, PhD, of the Erasmus MC Cancer Center in Rotterdam, the Netherlands, is presenting the findings during the SNO meeting, which was held November 17-20, 2016, in Scottsdale, Arizona.
“In an interview with Targeted Oncology, van den Bent discussed the trial’s significant findings, that agent’s toxicity profile, and what lies ahead for the investigational agent.”
“The FDA has approved atezolizumab (Tecentriq) for the treatment of patients with metastatic non–small cell lung cancer (NSCLC) who have progressed after a platinum-containing regimen and an FDA-approved targeted therapy for those patients harboring EGFR or ALK abnormalities.
“The approval is based on multiple clinical trials, the largest being the phase III OAK trial, which was presented at the 2016 ESMO Congress. In the study, atezolizumab reduced the risk of death by 26% compared with docetaxel in patients with advanced NSCLC following the failure of platinum-based chemotherapy. The median overall survival (OS) was improved by 4.2 months with the PD-L1 inhibitor versus chemotherapy. The survival benefit with atezolizumab was observed regardless of PD-L1 status or histology.”
