“On February 12, the U.S. Food and Drug Administration (FDA) accepted and granted Priority Review to Pfizer’s new drug application for lorlatinib. The Prescription Drug User Fee Act goal date for a decision by the FDA is in August 2018.
“Lorlatinib is an investigational, anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitor for the treatment of patients with ALK-positive metastatic non–small cell lung cancer (NSCLC) previously treated with one or more ALK tyrosine kinase inhibitors. It has been shown to be highly active in preclinical lung cancer models harboring chromosomal rearrangements of both ALK and ROS1. Lorlatinib was specifically designed to inhibit tumor mutations that drive resistance to other ALK inhibitors and to penetrate the blood-brain barrier.”
“The combination of nivolumab (Opdivo) and ipilimumab (Yervoy) improved progression-free survival (PFS) compared with chemotherapy in treatment-naïve patients with high tumor mutation burden (TMB) non–small cell lung cancer (NSCLC).
“Bristol-Myers Squibb (BMS), the manufacturer of both immunotherapies, announced the preliminary findings from part 1a of the phase III CheckMate-227 trial in a press release. The company did not report any further data.”
“The frontline indication for afatinib (Gilotrif) has been expanded by the FDA to include the treatment of patients with metastatic non–small cell lung cancer (NSCLC) whose tumors harbor uncommon EGFR alterations in L861Q, G719X, and/or S768I.
“The FDA initially approved afatinib in 2013 for the treatment of patients with metastatic NSCLC with exon 19 deletions or exon 21 L858R substitutions. In 2016, the FDA expanded the indication to include patients with squamous histology following progression on a platinum-based chemotherapy.”
“The addition of pembrolizumab to pemetrexed and cisplatin or carboplatin improved OS and PFS as first-line treatment for patients with metastatic nonsquamous non-small cell lung cancer, according to a manufacturer-issued press release.
Diagnosis of adenocarcinoma of the lung, a major subtype of non-small lung cancer (NSCLC), nowadays triggers mandatory testing of tumor tissue for alterations in four genes: EGFR, ALK, ROS1, and more recently, BRAF. If present, these alterations predict sensitivity to specific targeted drugs approved by the U.S. Food and Drug Administration (FDA) that work better and often longer than standard chemotherapy, and are better tolerated.
However, there are many more targetable/actionable genomic alterations (also known as “drivers”) in NSCLC. This blog post will briefly discuss most of them, with the goal of promoting molecular testing for more than the four “usual suspects” mentioned above. Some patients with these alterations may benefit from FDA-approved drugs or from enrollment in clinical trials that are testing additional drugs and drug combinations. Continue reading…
“The FDA has granted a priority review to a supplemental new drug application (sNDA) for the use of osimertinib (Tagrisso) as a first-line treatment for patients with non–small cell lung cancer (NSCLC) whose tumors harbor EGFR mutations (exon 19 deletions or exon 21 [L858R] substitution mutations).
“The sNDA is based on the phase III FLAURA study, in which frontline osimertinib reduced the risk of progression or death by 54% versus standard TKI therapy—erlotinib (Tarceva) or gefitinib (Iressa). In the double-blind study, the median progression-free survival (PFS) was 10.2 months (95% CI, 9.6-11.1) for standard therapy and 18.9 months (95% CI, 12.5-21.4) with osimertinib (HR, 0.46; 95% CI, 0.37-0.57; P <.0001).”
“A new combination therapy for the first line treatment of advanced non-squamous non-small-cell lung cancer (NSCLC) improves progression-free survival (PFS), according to results of the phase III IMpower150 trial presented at the ESMO Immuno Oncology Congress 2017.
” ‘This is the first phase III trial to report on the combination of chemotherapy, antiangiogenic treatment and immunotherapy as first line treatment for advanced non-squamous NSCLC,’ said lead author Professor Martin Reck, chief oncology physician, Department of Thoracic Oncology, Lung Clinic Grosshansdorf, Germany. ‘The trial met its co-primary endpoint of PFS and the preliminary results of the co-primary endpoint of overall survival (OS), although immature, look encouraging.’ ”
The human gut contains hundreds of species bacteria, which are known to contribute to various bodily functions (such as digestion, of course!) but they also shape our immune system. Now, recent research has revealed how our microbiomes (the abundant bacteria living in our bodies) may affect the efficacy of immune checkpoint blockade (ICB) in cancer treatment.
How it started: about two years ago, an American group of scientists led by Thomas Gajewski of the University of Chicago noticed that melanoma (and some other cancers’) growth in mice was influenced heavily by the type of bacteria found in the mouse gut. They worked with mice purchased from two different vendors, and realized that mice from one vendor had consistently slower-growing tumors. Bifidobacterium bacteria present in the mouse gut were pinpointed to be the culprit, because transfer of Bifidobacterium to mice that did not have it was able to slow down melanoma growth. Treatment with an immune anti-PD-L1 drug was effective in mice that had the bacteria, but not in mice lacking it. Continue reading…
“Adding Tecentriq (atezolizumab) to a treatment of Avastin (bevacizumab) and chemotherapy significantly prolonged the time to disease progression or death in people with previously untreated advanced non-squamous non-small cell lung cancer (NSCLC).
“The results stem from a Phase 3 trial of 1,202 people, with data also indicating better overall survival in patients treated with Tecentriq. Improved progression-free and overall survival were the two main trial outcome measures.”
