Phase II, Open-Label Study of Encorafenib Plus Binimetinib in Patients With BRAFV600-Mutant Metastatic Non–Small-Cell Lung Cancer
Targeted therapy in NSCLC, FCS was part of this trial.
This is a potential practice-changing study. Future data on overall-survival (OS) will be important to confirm results. Patient selection will also evolve over time especially in real-world practice. I presume more patients with stage II/III will get neoadjuvant therapy as opposed to a patient with a small lung nodule (stage I) taken to surgery, unless if there is significant OS for early stage patients as well.
Neoadjuvant or adjuvant chemotherapy confers a modest benefit over surgery alone for resectable non–small-cell lung cancer (NSCLC). In early-phase trials, nivolumab-based neoadjuvant regimens have shown promising clinical activity; however, data from phase 3 trials are needed to confirm these findings.
In this open-label, phase 3 trial, we randomly assigned patients with stage IB to IIIA resectable NSCLC to receive nivolumab plus platinum-based chemotherapy or platinum-based chemotherapy alone, followed by resection. The primary end points were event-free survival and pathological complete response (0% viable tumor in resected lung and lymph nodes), both evaluated by blinded independent review. Overall survival was a key secondary end point. Safety was assessed in all treated patients.
The median event-free survival was 31.6 months (95% confidence interval [CI], 30.2 to not reached) with nivolumab plus chemotherapy and 20.8 months (95% CI, 14.0 to 26.7) with chemotherapy alone (hazard ratio for disease progression, disease recurrence, or death, 0.63; 97.38% CI, 0.43 to 0.91; P=0.005). The percentage of patients with a pathological complete response was 24.0% (95% CI, 18.0 to 31.0) and 2.2% (95% CI, 0.6 to 5.6), respectively (odds ratio, 13.94; 99% CI, 3.49 to 55.75; P<0.001). Results for event-free survival and pathological complete response across most subgroups favored nivolumab plus chemotherapy over chemotherapy alone. At the first prespecified interim analysis, the hazard ratio for death was 0.57 (99.67% CI, 0.30 to 1.07) and did not meet the criterion for significance. Of the patients who underwent randomization, 83.2% of those in the nivolumab-plus-chemotherapy group and 75.4% of those in the chemotherapy-alone group underwent surgery. Grade 3 or 4 treatment-related adverse events occurred in 33.5% of the patients in the nivolumab-plus-chemotherapy group and in 36.9% of those in the chemotherapy-alone group.
In patients with resectable NSCLC, neoadjuvant nivolumab plus chemotherapy resulted in significantly longer event-free survival and a higher percentage of patients with a pathological complete response than chemotherapy alone. The addition of nivolumab to neoadjuvant chemotherapy did not increase the incidence of adverse events or impede the feasibility of surgery.

FCS medical oncologist and hematologist Lowell L. Hart, MD, FACP was first-author a study with FCS co-authors President and Managing Physician Lucio N. Gordan, MD, Director of Pharmacy Operations Kristen Boykin, Senior Vice President & Data Officer Trevor Heritage, PhD, and (Retired) Vice President of Pharmacy Services Ray Bailey BPharm, RPh, that evaluated ES-SCLC patients with chemotherapy-induced myelosuppression over a seven-year period, from January 2013 through December 2020. Within this cohort, 98% of the patients experienced at least one myelosuppressive episode following chemotherapy treatment, leading to the need for supportive care, creating additional costs in health care management and time lost in treatment for ES-SCLC.
Suddenly met-NSCLC is a crowded space. This study did not conclude that T+D+CT was better than D+CT, the findings showed that D+CT was better than CT alone. The addition of T to D+CT improved the PFS and OS trend but I don’t think this was a homerun result. There was not a significant OS benefit and further follow-up will declare these results. Also an improved outcomes were not seen in the non-squamous population. The pembrolizumab studies have 5+ years of follow-up and an improvement in PFS and OS across NSCLC subtypes.
Interesting study which the demonstrates the importance of prescriptive approach to detect NSCLC. Hopefully, in the future ctDNA may enhance or replace LDCT ability to detect patients with stage I/II disease.
Lots of progress to be accomplished here. Increased standardization of care, quality metrics based on guideline-adherence and best practices remain critical to progress.
