“Data from two separate phase 3 studies to be presented at the ESMO 2017 Congress in Madrid, show alectinib’s particular central nervous system (CNS) activity in patients with advanced non-small cell lung cancer involving a mutation of the anaplastic lymphoma kinase gene (ALK-positive NSCLC).
Findings from the ALUR trial (1), as well as a secondary analysis of the ALEX trial (2) show alectinib can significantly decrease CNS progression of NSCLC, both in the first-line as well as the second-line treatment setting.
” ‘Patients with NSCLC have a high risk of CNS and brain metastases,’ commented Prof. Fiona Blackhall, from the University of Manchester and The Christie Hospital, UK.”
“Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced results from the global phase III ALUR study showing that Alecensa® significantly reduced the risk of disease worsening or death (progression-free survival, PFS) by 85% compared to chemotherapy in patients with anaplastic lymphoma kinase (ALK)-positive advanced non-small cell lung cancer (NSCLC), who had progressed following treatment with platinum-based chemotherapy and crizotinib (hazard ratio [HR]=0.15, 95% CI: 0.08-0.29, p<0.001). Median PFS reported by the investigators, the primary endpoint of the study, was 9.6 months in patients who received Alecensa (95% CI: 6.9-12.2) compared with 1.4 months (95% CI: 1.3-1.6) in those who received chemotherapy. Median PFS assessed by an independent review committee (IRC), a secondary endpoint, was 7.1 months for patients who received Alecensa versus 1.6 months for patients who received chemotherapy (HR=0.32, 95% CI 0.17–0.59; p<0.001). The safety profile of Alecensa was consistent with that observed in previous studies and compared favourably to chemotherapy.”
“Yesterday’s historic FDA approval of the first engineered T-cell treatment for cancer, Novartis’ Kymriah (tisagenlecleucel), was accompanied by inevitable questions about how the product would be priced. In the end, Novartis set the price at $475,000, which was lower than many analysts had predicted, considering the treatment is designed to cure some forms of acute lymphoblastic leukemia (ALL)—and in clinical trials it did just that for most patients.”
“Pembrolizumab (Keytruda) induced an overall response rate (ORR) of 33% in patients with extensive-stage small cell lung cancer (SCLC), according to findings from the open-label, phase Ib KEYNOTE-028 trial published in the Journal of Clinical Oncology.
“One patient (4.2%) experienced a complete response, 7 (29.2%) had partial responses, and 1 (4.2%) had stable disease for less than 6 months. Thirteen patients (54.2%) experienced disease progression as the best overall response.”
“Patients with unresectable, or inoperable, lung cancer are often given a dismal prognosis, with low rates of survival beyond a few years. Researchers exploring combination therapies have recently discovered improved survival rates by up to one year when patients treated with a newly formulated chemotherapy regimen are also given radiation therapy.
“A group of patients with metastatic non-small-cell lung cancer (mNSCLC) who had already been enrolled in a clinical trial were given radiation therapy, in addition to their treatment with a novel chemotherapy formulation, mPEBev, which was designed for its immune-modulating and anti-angiogenic effects. The mPEBev regimen is composed of fractionated cisplatin, oral etoposide, and bevacizumab, a monoclonal antibody that inhibits blood vessel growth in the tumor. Treatments were administered metronomically, spaced out in the safest possible doses to reduce side-effects and toxicity.”
Medical guidelines for treatment of newly diagnosed non-small cell lung cancer (NSCLC) mandate upfront testing of tumor tissue for mutations in the EGFR gene (as well as ALK and ROS gene translocation). EGFR mutations are found in 10 to 15% of white patients, but in patients of East Asian origin such mutations are in encountered in approximately 48%. However, with new data and drugs entering the playing field, newly diagnosed patients’ treatment decisions could become more complex.
There is a good reason to test for EGFR mutations: the accumulated data show that, compared to first-line chemotherapy, treatment with drugs that inhibit the activity of EGFR in patients with activating EGFR mutations improves patients’ median progression-free survival (PFS) time from 4.6 to 6.9 months to 9.6 to 13.1 months, and has a higher objective response rate (ORR). Moreover, EGFR inhibitors are associated with a significantly lower incidence of adverse effects and better control of disease symptoms. Continue reading…
“New research suggests long-term, high-dose supplementation with vitamins B6 and B12—long touted by the vitamin industry for increasing energy and improving metabolism—is associated with a two- to four-fold increased lung cancer risk in men relative to non-users.
“Risk was further elevated in male smokers taking more than 20 mg of B6 or 55 micrograms of B12 a day for 10 years. Male smokers taking B6 at this dose were three times more likely to develop lungcancer. Male smokers taking B12 at such doses were approximately four times more likely to develop the disease compared to non-users.”
“An update of the American Society of Clinical Oncology (ASCO) clinical practice guideline clarifies the role of immunotherapy in the treatment of patients with advanced non-small-cell lung cancer (NSCLC). The update also provides new recommendations on the use of targeted therapies for patients with changes in tumor EGFR, ALK, and ROS1 genes.
” ‘Treatment for lung cancer has become increasingly more complex over the last several years. This guideline update provides oncologists the tools to choose therapies that are most likely to benefit their patients,’ said Nasser Hanna, MD, co-chair of the Expert Panel that developed the guideline update.”
