“Upfront treatment with the combination of bevacizumab (Avastin) and erlotinib (Tarceva) is superior to erlotinib alone as for patients with non–small cell lung cancer (NSCLC) harboring EGFR mutations, according to results of a preplanned interim analysis of the phase III study known as NEJ026.
“The analysis showed a median progression-free survival (PFS) by independent review (the primary endpoint) of 16.9 months with the bevacizumab/erlotinib combination compared with 13.3 months with erlotinib by itself, said Naoki Furuya, MD, PhD, at the 2018 ASCO Annual Meeting.”
“The combination of nivolumab (Opdivo) and low-dose ipilimumab (Yervoy) reduced the risk of progression or death by 52% compared with standard platinum doublet chemotherapy for patients with metastatic PD-L1–negative, tumor mutation burden (TMB)-high non–small cell lung cancer (NSCLC), according to findings from the phase III CheckMate 227 trial presented at the 2018 ASCO Annual Meeting.
“In the PD-L1–negative (<1% expression), TMB-high (≥10 mutations/megabase) subgroup, regardless of histology, median progression-free survival (PFS) with nivolumab/ipilimumab was 7.7 months compared with 5.3 months for chemotherapy and 6.2 months for nivolumab and chemotherapy. The 1-year PFS rate was 45% with nivolumab/ipilimumab compared with 27% for nivolumab/chemotherapy and just 8% for chemotherapy.”

“Updated results of the global phase III ALEX trial comparing alectinib with crizotinib as first-line treatment against ALK-positive non-small cell lung cancer show a median progression-free survival (PFS) of 34.8 months in 152 patients treated with alectinib versus 10.9 months in 151 patients treated with crizotinib.
” ‘Think of it like a horse race, only it’s not about who crosses the finish line first, but how far the horses can run,’ says D. Ross Camidge, MD, Ph.D., the Joyce Zeff Chair in Lung Cancer Research at the University of Colorado Cancer Center, director of Thoracic Oncology at the CU School of Medicine, and the study’s first author. ‘In this trial, it’s as if half of the people “riding” crizotinib had exhausted their horses at about 11 months. For patients on alectinib, when this trial first started reporting data last year, more than half were still on their horses, still running. Now enough time has elapsed to estimate the median performance of these alectinib ‘horses’ more accurately.’ ”
“Patients with advanced non-small-cell lung cancer (NSCLC) treated with pembrolizumab (Keytruda) had a greater median survival than patients treated with standard chemotherapy, even if the former had low levels of PD-L1, researchers reported here.
“Depending on the percentage of PD-L1 expression in the tumor, survival was between 4 and 8 months longer for patients treated with immunotherapy alone versus those treated with chemotherapy, according to Gilberto Lopes, MD, MBA, of the Sylvester Comprehensive Cancer Center at the University of Miami, and colleagues.”
“Adding atezolizumab (Tecentriq) to nab-paclitaxel (Abraxane) and carboplatin in the frontline setting significantly improved overall survival (OS) in patients with advanced non–small cell lung cancer (NSCLC), according to findings from the phase III IMpower130 study.
“Atezolizumab also improved progression-free survival (PFS), the coprimary endpoint of the IMpower130 study, according to Genentech (Roche), the manufacturer of the PD-L1 inhibitor. The company plans to share the study data at an upcoming oncology meeting.”
“The results reveal that 152 patients treated with alectinib showed a median progression-free survival (PFS) of 34.8 months compared with just 10.9 months in the 151 patients who were treated with crizotinib.”
“Priority review of Roche’s supplemental Biologics License Application means the FDA will decide whether or not to approve the therapy within six months instead of the standard 10 months. A decision is now expected by Sept. 5. To be granted priority review, a therapy candidate must show potential to provide significant benefits for the treatment, prevention, or diagnosis of a disease.”
Immune checkpoint inhibitor drugs that target the proteins PD-1 and PD-L1 are by now well established in the treatment of non-small cell lung cancer (NSCLC). In 2015, the U.S. Food and Drug Administration (FDA) approved nivolumab (Opdivo), an anti-PD-1 drug, for treatment of patients with metastatic NSCLC who progressed or relapsed after platinum-based chemotherapy. Atezolizumab (Tecentriq), an anti-PD-L1 drug, was approved in 2016 for treatment of NSCLC patients in the same situation. In October 2016, the FDA approved Pembrolizumab (Keytruda), a competing anti-PD-1 antibody, as first-line treatment in metastatic NSCLC patients whose tumors have high expression levels of the PD-L1 protein.
With these approvals, the stage was set to move these drugs into combination treatments that may increase their efficacy. Not surprisingly, combinations with chemotherapy have now been explored, among other possibilities. Continue reading…
