“Findings from a phase III clinical trial for advanced lung cancer patients could help oncologists better predict which patients are likely to receive the most benefit from immunotherapy as a first-line treatment based on the unique molecular characteristics of their tumor, according to a new study reported by a global team led by David Carbone, MD, PhD, of The Ohio State University Comprehensive Cancer – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James).
“In this study, researchers compared the effectiveness of the immunotherapy drug nivolumab (pronounced ‘nye VOL ue mab,’ marketed at Opdivo), with standard-of-care chemotherapy in 541 patients with previously untreated or recurrent non-small cell lung cancer (NSCLC) that expressed PDL-1 antibodies.”
“The FDA has granted a priority review to ceritinib (Zykadia) as a first-line treatment for patients with ALK-positive, metastatic non–small cell lung cancer (NSCLC), according to Novartis, the manufacturer of the second-generation ALK inhibitor.
“The priority review is based on findings from the phase III ASCEND-4 trial, in which ceritinib reduced the risk of disease progression or death by 45% compared with standard chemotherapy. The median progression-free survival (PFS) benefit favoring ceritinib was 8.5 months (HR, 0.55; 95% CI, 0.42-0.73; P <.001).”
“Treatment with first-line avelumab yielded promising clinical benefit and durable antitumor activity in patients with advanced non–small cell lung cancer (NSCLC), according to a presentation at the IASLC 17th World Conference on Lung Cancer.
“After a median follow-up of 13 weeks, the objective response rate with the anti-PD-L1 immunotherapy agent was 22.4% (95% CI, 16.2-29.8) and the median progression-free survival (PFS) was 17.6 weeks (95% CI, 11.6-23.6) among 156 patients who participated in one of the NSCLC cohorts of the wide-ranging JAVELIN Solid Tumor trial, Claire Verschraegen, MD, director, The University of Vermont Cancer Center, said in describing early analysis data at the conference in Vienna.”
“G1 Therapeutics, Inc., a clinical-stage oncology company, announced today a clinical trial collaboration with Genentech, a member of the Roche Group. A Phase 2 clinical trial is expected to begin in the first half of 2017 and will evaluate the combination of Genentech’s immune checkpoint, anti-PD-L1 antibody Tecentriq® (atezolizumab) with G1’s CDK4/6 inhibitor trilaciclib (G1T28) as a first-line treatment for patients with small-cell lung cancer (SCLC) receiving chemotherapy.”
“Although nivolumab (Opdivo) has demonstrated a clear survival advantage compared with chemotherapy in patients with progressive non–small cell lung cancer (NSCLC) who express PD-L1 in their tumor cells, the same cannot be said for those who are PD-L1–negative.
“As a result, researchers are seeking to elicit antitumor activity in a broader range of patients, notably through a multiarm trial evaluating the PD-1 inhibitor along with combinatorial approaches.
“CheckMate-227 (NCT02477826) is a phase III, open-label, randomized trial for patients with chemotherapy-naïve stage IV or recurrent NSCLC. The trial will enroll patients into separate groups according to PD-L1 expression status (≥1% or <1%).”
“Merck & Co has won U.S. approval to market its immunotherapy Keytruda for use in previously untreated lung cancer patients two months ahead of schedule, making it the only such drug cleared for first-line treatment.
“The green light from the Food and Drug Administration (FDA), announced by the U.S. drugmaker late on Monday, confirms Merck’s leading position in the hot area of medicines that fight tumors by harnessing the body’s immune system.
“Keytruda’s latest approval is for treating first-line metastatic non-small cell lung cancer (NSCLC) in patients with high-levels of a protein called PD-L1, which makes them more receptive to immunotherapy.”
“The addition of PD-1 antibody pembrolizumab to standard first-line chemotherapy for treatment-naïve advanced non-small-cell lung cancer significantly improves response rates and progression-free survival, researchers reported at the ESMO 2016 Congress in Copenhagen today.
“Pembrolizumab is a class of immunotherapeutic anti-cancer drugs called checkpoint inhibitors, which target the mechanism the tumour uses to shut down the body’s immune response.”
“Nivolumab (Opdivo) and ipilimumab (Yervoy), a chemotherapy-free regimen, showed activity as a first-line therapy for patients who have advanced non-small cell lung cancer (NSCLC), according to a preliminary clinical trial that was presented at this year’s World Conference on Lung Cancer.
“Four different regimens of nivolumab, the PD-1 inhibitor, and ipilimumab, the anti-CTLA-4 antibody, led to response rates of 13% to 39% in 148 patients with no prior exposure to systemic therapy. The combination produced deep and durable responses, with a low rate of treatment-emergent grade 3/4 adverse events (AEs) leading to discontinuation.
“ ‘Clinical activity was observed regardless of tumor PD-L1 expression,’ said lead investigator Naiyer A. Rizvi, MD, director of Thoracic Oncology and Immunotherapeutics at Columbia University Medical Center. ‘We have preliminary evidence of greater activity in tumors that have 1% or greater PD-L1 expression. The median disease control rate [response plus stable disease] was not reached in any arm, regardless of PD-L1 expression.’ “
“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.”
