AbstractCancers harboring mutations in the Kirsten rat sarcoma homolog (KRAS) gene have been associated with poor prognosis and lack of targeted therapies. KRAS mutations occur in approximately one in four patients diagnosed with non-small cell lung cancer (NSCLC) with KRAS G12C mutations harbored at approximately 11–16%. Research into KRAS-driven tumors and analytical chemistry have borne a new class of selective small molecules against the KRAS G12C isoform. Phase II data for sotorasib (AMG510) has demonstrated a 37.1% overall response rate (ORR). Adagrasib (MRTX849) has demonstrated a 45% ORR in an early study. While single agent efficacy has been seen, initial data suggest combination approaches are an opportunity to improve outcomes. Here, we present perspectives on the initial progress in targeting KRAS G12C, examine co-mutations evident in KRAS G12C NSCLC, and comment on potential future combinatorial approaches including SHP2, SOS1, MEK, EGFR, mTOR, CDK, and checkpoint blockade which are currently being evaluated in clinical trials. As of May 28, 2021, sotorasib has achieved US FDA approval for patients with KRAS G12C mutant lung cancer after one line of a prior therapy.

Favorable Safety

Lurbinectedin is a marine-derived drug that inhibits transcription, a process that is frequently dysregulated in small cell lung cancer. The activity of lurbinectedin has been studied in many solid tumors, showing not only promising results but also a favorable safety profile. In relapsed small cell lung cancer, the drug has shown encouraging activity both as a single agent and in combination with doxorubicin, paclitaxel or irinotecan. The US FDA has recently granted accelerated approval to lurbinectedin monotherapy in this setting. This article provides an update on available data and ongoing studies of lurbinectedin in small cell lung cancer, including Phase I combination trials, the basket Phase II trial and the ATLANTIS Phase III trial.

Improved Outcomes

KRAS-mutant non-small-cell lung cancer is the most common molecular driver of lung adenocarcinoma in western populations. No  KRAS specific therapy has been approved by the FDA until 2021. Despite significant heterogeneity in comutations, patients typically receive single-agent immunotherapy or chemoimmunotherapy as standard first-line therapy. It is unclear whether KRAS mutations predict outcomes with immunotherapy; however, there is emerging data suggesting improved outcomes in patients with a  TP53 comutation and worse outcomes in patients with a  STK11/LKB1 or  KEAP1 comutation.

PurposeBecause of promising efficacy signals in single-arm studies, a placebo-controlled, double-blind, randomized phase II trial was designed to assess the efficacy and safety of adding bevacizumab to first-line standard chemotherapy for treatment of extensive-stage small-cell lung cancer (SCLC).Patients and MethodsPatients with SCLC were randomly assigned to receive bevacizumab or placebo, with cisplatin or carboplatin plus etoposide, for four cycles followed by single-agent bevacizumab or placebo until progression or unacceptable toxicity. The primary end point was progression-free survival (PFS).ResultsFifty-two patients were randomly assigned to the bevacizumab group and 50 to the placebo group; 69% versus 66%, respectively, completed four cycles of therapy. Median PFS was higher in the bevacizumab group (5.5 months) than in the placebo group (4.4 months; hazard ratio [HR], 0.53; 95% CI, 0.32 to 0.86). Median overall survival (OS) was similar for both groups (9.4 v 10.9 months for bevacizumab and placebo groups, respectively), with an HR of 1.16 (95% CI, 0.66 to 2.04). Overall response rates were 58% (95% CI, 43% to 71%) for the bevacizumab group and 48% (95% CI, 34% to 62%) for the placebo group. Median duration of response was 4.7 months for the bevacizumab group and 3.2 months for the placebo group. In the bevacizumab and placebo groups, 75% versus 60% of patients, respectively, experienced one or more grade 3 or higher adverse events. No new or unexpected safety signals for bevacizumab were observed.ConclusionThe addition of bevacizumab to cisplatin or carboplatin plus etoposide for treatment of extensive-stage SCLC improved PFS, with an acceptable toxicity profile. However, no improvement in OS was observed.

Purpose Sorafenib, an oral multikinase inhibitor, has shown preliminary activity in non–small-cell lung cancer (NSCLC). Patients with advanced NSCLC were treated with erlotinib with or without sorafenib in this multicenter phase II trial. Patients and Methods Key eligibility criteria included the following: stage IIIB or IV NSCLC; one to two prior regimens; Eastern Cooperative Oncology Group performance status of 0 to 2; and measurable disease. Patients were randomly assigned 2:1 to sorafenib (400 mg orally twice a day) plus erlotinib (150 mg orally daily) or placebo plus erlotinib and stratified by squamous/nonsquamous histology and prior bevacizumab. Treatment efficacy, measured by progression-free survival (PFS) and overall response rate (ORR), was compared. Treatment of 168 patients allowed detection of 40% improvement in the historical PFS of 2.2 months with single-agent erlotinib. Results One hundred sixty-eight patients enrolled from February 2008 to February 2009. Clinical characteristics of the two groups were similar. ORRs for sorafenib/erlotinib and placebo/erlotinib were 8% and 11%, respectively (P = .56); disease control rates were 54% and 38%, respectively (P = .056). Median PFS was 3.38 months for sorafenib/erlotinib versus 1.94 months for placebo/erlotinib (hazard ratio, 0.86; 95% CI, 0.60 to 1.22; P = .196). Seventy-two patients consented to analyses of tumor epidermal growth factor receptor (EGFR). In 67 patients with EGFR wild-type (WT) tumors, median PFS was 3.38 months for sorafenib/erlotinib versus 1.77 months for placebo/erlotinib (P = .018); median overall survival (OS) was 8 months for sorafenib/erlotinib versus 4.5 months for placebo/erlotinib (P = .019). An OS advantage for sorafenib/erlotinib was suggested among 43 patients with fluorescent in situ hybridization (FISH) EGFR-negative tumors (P = .064). Both regimens were tolerable, with modest toxicity increase with sorafenib. Conclusion Although there was little difference in ORR or PFS, subset analyses in EGFR WT and EGFR FISH–negative patients suggest a benefit for the combination of erlotinib/sorafenib compared with single-agent erlotinib with respect to PFS and OS.
