With a median follow-up of more than 2.5 years, sintilimab added to chemotherapy improved OS in patients with advanced, nonsquamous NSCLC. The median OS was 24.2 months with sintilimab and 16.8 months with chemotherapy alone. Nearly half of patients in the chemotherapy-only arm crossed over to receive sintilimab after disease progression. When the data were adjusted for the crossover effect, the OS benefit derived from sintilimab was more pronounced.

This comprehensive review highlights the history of discovering RAS and the decades of studies targeting KRAS-driven lung cancer, to the present applications. Although KRAS inhibitors have 36%–45% objective response rates with a median duration of response of 10 months, many tumors do not respond, and a variety of mechanisms of resistance have been observed, including new KRAS alterations, activation of alternate RTK pathway proteins, bypass pathways, and transcriptional remodeling. The authors conclude with a discussion of ongoing clinical trials aimed at overcoming resistance to KRAS inhibitors.

In this trial of nivolumab + chemotherapy vs. chemotherapy alone, nivolumab prolonged EFS by nearly 11 months and improved the pathologic complete response rate more than tenfold. There was also a trend toward improved OS with nivolumab. The study also reported an EFS improvement with nivolumab in both squamous and non-squamous NSCLC. Grade 3-4 treatment-related adverse events occurred in 34% of patients in the nivolumab arm and 37% of those in the chemotherapy-alone arm.

In an interim look at the SKYSCRAPER-01 study, investigators found tiragolumab plus atezolizumab didn’t meaningfully slow tumor progression compared to atezolizumab alone in patients with advanced, newly diagnosed non-small cell lung cancer (NSCLC). Tiragolumab has now fallen short in two phase 3 lung cancer trials, having already missed its study objectives in advanced SCLC earlier this year.

A phase II study of durvalumab alone or combined with the anti-CD73 monoclonal antibody oleclumab or anti-NKG2A monoclonal antibody monalizumab as consolidation therapy in patients with unresectable stage III NSCLC and no progression after concurrent chemoradiotherapy. With a median follow-up of 11.5 months, both combinations increased ORR and prolonged PFS versus durvalumab alone. Safety was similar across arms with no new or significant safety signals identified with either combination.

An 87-year-old white man presented to a hospital emergency surgical department with two round, grayish-brown nodules on his abdomen. He had no other complaints except feeling tired and dizzy for the last few months. He had a 120 pack-year smoking history but was not taking any medications and had not experienced a cough, chest pain, shortness of breath, or other breathing problems.
