“In a study reported in the Journal of Clinical Oncology, Johung and colleagues identified factors that distinguished survival rates among patients with ALK-rearranged non–small cell lung cancer (NSCLC) and brain metastasis.
“The study included 90 patients from six institutions. Of them, 84 patients had received radiotherapy to the brain, consisting of stereotactic radiosurgery or whole-brain radiotherapy, and 86 patients had received tyrosine kinase inhibitor therapy (crizotinib [Xalkori] in 84 and a second-generation tyrosine kinase inhibitor in 41).”
“Pfizer Inc. announced today that PROFILE 1029, a Phase 3 study of anaplastic lymphoma kinase (ALK) inhibitor XALKORI® (crizotinib), met its primary objective of significantly prolonging progression-free survival (PFS) in previously untreated East Asian patients with ALK-positive advanced non-small cell lung cancer (NSCLC) when compared to a standard chemotherapy doublet. In this study, XALKORI was used as the first systemic therapy for patients with advanced ALK-positive NSCLC, and patients could have received therapy and/or surgery for early stage disease before they were diagnosed with metastatic disease.
“The adverse events observed with XALKORI in the study were generally consistent with findings from previous trials. No unexpected adverse events were observed. Efficacy and safety data from PROFILE 1029 will be submitted for presentation at a future medical meeting.”
In March 2011, Janet Freeman-Daily was about to take a long family trip to China. She’d been coughing for a while, so she asked her doctor for an antibiotic as a precaution before leaving. Even so, she came back in May with a respiratory infection that wouldn’t go away.
Her doctor ordered an X-ray and then a CT scan. “Before I got home, they called and said they’d like to do a bronchoscopy,” Janet says. The scan revealed a 7-cm mass in her left lung, and biopsies showed it was non-small cell lung cancer (NSCLC) and that it had spread to several lymph nodes. Continue reading…
“The presence or absence of mutations in advanced non-small cell lung cancer (NSCLC) should guide selection of first-line systemic therapy, according to an updated clinical guideline from the American Society of Clinical Oncology.
“Patients with squamous-cell tumors that have no gene alterations should begin treatment with combination platinum-based cytotoxic chemotherapy, so long as they have good performance status (0 or 1). Optionally, bevacizumab (Avastin) may be added when the platinum agent is carboplatin. For patients with performance status 2, either chemotherapy or palliative care alone is an acceptable option.
“In the presence of sensitizing EGFR mutations, appropriate first-line therapy is afatinib (Gilotrif), erlotinib (Tarceva), or gefitinib (Iressa). Treatment should begin with crizotinib (Xalkori) when patients have tumors with ALK or ROS1 rearrangements, as published online in the Journal of Clinical Oncology.”
In October 2013, Lisa Goldman had a dry cough that wouldn’t go away. “It was bad enough that I went to the doctor, which I don’t do very often,” she says. He ordered a chest radiograph, said her lungs were clear, prescribed codeine cough syrup, and sent her home.
But she kept coughing, so she kept coming back. On her second visit, her doctor said her airways were irritated and prescribed an inhaler and antibiotics. By her third visit, she’d begun to cough up a bit of blood, but her doctor just repeated that her airways were irritated and prescribed steroids. Continue reading…
“An experimental Pfizer Inc drug that aims to help lung cancer patients with specific genetic mutations who have stopped responding to the company’s Xalkori was showing promise in a small, early stage study, according to preliminary data revealed on Wednesday.
“The ongoing Phase I trial of the drug, PF-3922, was designed to determine if there is a maximum tolerable dose and which dose or doses to test in future larger trials.
“But researchers found some early evidence of efficacy, according to a brief summary of the study that will be presented at the upcoming American Society of Clinical Oncology (ASCO)meeting in Chicago later this month.
“Of 15 patients evaluated for efficacy, six, or 40 percent, had partial responses, meaning tumor shrinkage of at least 30 percent. Intracranial responses were observed in five patients, indicating that the drug had successfully crossed the blood/brain barrier to attack tumors in the brain, which are common in advanced, or metastatic, lung cancer.
” ‘There’s encouraging clinical activity despite that it’s an early study,’ said Ronit Simantov, head of medical affairs for Pfizer oncology.”
“Pfizer Inc. announced today that XALKORI® (crizotinib) received Breakthrough Therapy designation by the U.S. Food and Drug Administration (FDA) for the potential treatment of patients with ROS1-positive non-small cell lung cancer (NSCLC). Occurring in approximately one percent of NSCLC cases1, ROS1-positive NSCLC represents a particular molecular subgroup of NSCLC.2 XALKORI currently is approved in the U.S. for the treatment of patients with metastatic NSCLC whose tumors are anaplastic lymphoma kinase (ALK)-positive as detected by an FDA-approved test.
“Enacted as part of the 2012 FDA Safety and Innovation Act (FDASIA), Breakthrough Therapy designation is intended to expedite the development and review of a potential new medicine if it is “intended to treat a serious or life-threatening disease and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies.”3The Breakthrough Therapy designation is distinct from the FDA’s other mechanisms to expedite drug development and review.4
“ ‘We are excited that the FDA has granted Breakthrough Therapy designation for XALKORI as a potential treatment for patients with ROS1-positive NSCLC,’ said Dr. Mace Rothenberg, senior vice president of Clinical Development and Medical Affairs and chief medical officer for Pfizer Oncology. ‘XALKORI pioneered precision medicine for ALK-positive metastatic NSCLC, and ROS1 represents a second molecular subgroup of NSCLC in which XALKORI has demonstrated a level of anti-tumor activity that can potentially make a real difference for patients.’ ”
“In a retrospective study in the European EUROS1 cohort reported in the Journal of Clinical Oncology, Mazières found that crizotinib (Xalkori) treatment was associated with an 80% response rate in patients with stage IV lung adenocarcinoma with ROS1 rearrangement.
“The study involved 31 patients who received crizotinib therapy through individual off-label use. Patients had a median age of 50.5 years, 64.5% were women, and 67.7% were never-smokers. Patients had received zero (n = 1), one (n = 9), two (n = 5), three (n = 3), or more than three (n = 13) lines of chemotherapy before crizotinib.
“Among 30 patients evaluated for response, 24 (80.0%) had objective response, including complete response in 5; 2 had stable disease (disease control rate of 86.7%); and 4 had disease progression. Median progression-free survival was 9.1 months, and 12-month progression-free survival was 44%. No unexpected adverse effects were observed…
“The investigators concluded: ‘Crizotinib was highly active at treating lung cancer in patients with a ROS1 rearrangement, suggesting that patients with lung adenocarcinomas should be tested for ROS1. Prospective clinical trials with crizotinib and other ROS1 inhibitors are ongoing or planned.’ ”
“Novartis announced today that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency adopted a positive opinion for Zykadia® (ceritinib) to treat adult patients with anaplastic lymphoma kinase (ALK)-positive advanced non-small cell lung cancer (NSCLC) previously treated with crizotinib. If approved in the European Union (EU), Zykadia will be the first treatment option to address an unmet medical need for patients with ALK+ NSCLC previously treated with crizotinib.
” ‘Patients with advanced ALK+ NSCLC have few options when their cancer does not respond to currently approved therapy,’ said Alessandro Riva, MD, Global Head, Novartis Oncology Development and Medical Affairs. ‘As a leader in the development of precision oncology medicines, Novartis is committed to developing and bringing to market new treatments for patients with ALK+ NSCLC. This positive CHMP opinion for Zykadia brings us one step closer to providing the lung cancer community with new hope in the fight against this terrible disease.’
“Each year, there are 1.6 million people diagnosed with lung cancer, the leading cause of cancer death worldwide. The most common type of lung cancer is NSCLC, accounting for 85-90% of all cases. Of those, 2-7% are driven by a rearrangement of the ALK gene, which increases the growth of cancer cells and can be identified by a molecular test of the cancer tumor. Despite significant treatment advances for patients with ALK+ NSCLC, disease progression is often inevitable and more treatment options are needed.”
