Phase 3 BGB-A317-307 trial results showed statistically significant improvements in progression-free survival with tislelizumab plus chemotherapy versus chemotherapy alone in Chinese patients with untreated advanced squamous non–small cell lung cancer.

“Importantly, the separation among the curves seems to be observed over time and, indeed, survival at 2 years improves from 14% [of participants] in the control arm to 22% on the experimental arm. The magnitude of the benefit is very similar and very consistent across all the prespecified subgroups of patients analyzed, including those treated with cisplatin or those patients with liver or brain metastases.”

The FDA has approved ramucirumab in combination with erlotinib for the first-line treatment of patients with metastatic non–small cell lung cancer harboring EGFR exon 19 deletions or exon 21 mutations.

Mark M. Awad, MD, PhD, discusses the characterization of patients with non–small cell lung cancer who have MET exon 14 skipping alterations and potential acquired resistance mechanisms.

"CheckMate 9LA met its primary end point of overall survival at the pre-planned interim analysis…With early separation of overall survival curves and lower progressive disease rates as best overall response, the hypothesis for this study design was validated."

Modest survival benefits were observed in patients with extensive-stage small cell lung cancer who received the combination of pembrolizumab and etoposide plus platinum compared with patients who received EP and placebo. Although progression-free survival rates reached the threshold for significance, overall survival rates failed to reach the prespecified threshold, according to data from the phase 3 KEYNOTE-604 trial.

"Based on these results, we note that the combination of nivolumab and ipilimumab, which is now approved by the United States FDA, is a novel chemotherapy-sparing first-line treatment approach for advanced-stage non-small-cell lung cancer."

"Trastuzumab deruxtecan demonstrated clinical activity in this interim analysis, with a high ORR and durable response rate in a heavily pretreated population of patients with HER2-mutated NSCLC."

Frontline treatment with the TIGIT inhibitor tiragolumab plus atezolizumab demonstrated greater efficacy versus single-agent checkpoint inhibitor therapy in locally advanced or metastatic non–small cell lung cancer, according to results of the phase 2 CITYSCAPE trial reported at the 2020 American Society of Clinical Oncology Virtual Scientific Program.

"Prior administration of chemotherapy is associated with increased risk of death [from COVID-19] while immunotherapy and tyrosine kinase inhibitors are not."

Shared insight on recent advances in KRAS-mutant NSCLC, with a focus on new therapies on the horizon.

Nivolumab plus ipilimumab in combination with chemotherapy was granted approval for the frontline treatment of patients with metastatic or recurrent non–small cell lung cancer who do not harbor EGFR or ALK genomic tumor abberations.
