KRAS mutations are identified in approximately 30% of patients with non-small cell lung cancer (NSCLC). Novel direct inhibitors of KRAS G12C have shown activity in early-phase clinical trials. We hypothesized that patients with KRAS G12C mutations may have distinct clinical characteristics and responses to therapies. ⋯ We provide outcome data for a large series of patients with KRAS G12C-mutant NSCLC with available therapies, demonstrating that responses and duration of benefit with available therapies are similar to those seen in patients with KRAS non-G12C mutations. Strategies to incorporate new targeted therapies into the current treatment paradigm will need to consider outcomes specific to patients harboring KRAS G12C mutations.

On April 22, 2020, the FDA granted accelerated approval to sacituzumab govitecan-hziy (TRODELVY; Immunomedics, Inc.) for the treatment of patients with metastatic triple-negative breast cancer (mTNBC) who have received at least two prior therapies for metastatic disease. Approval was based on data from the IMMU-132-01 trial, a single-arm, multicohort, multicenter, phase I/II trial of sacituzumab govitecan. The assessment of efficacy was based on 108 patients with mTNBC who had previously received at least two prior lines of therapy in the metastatic setting and who received sacituzumab govitecan 10 mg/kg i.v. ⋯ The ORR was 33.3% [36/108; 95% confidence interval (CI), 24.6-43.1], and median DoR among responders was 7.7 months (95% CI, 4.9-10.8). The most common adverse reactions occurring in ≥25% of patients were nausea, neutropenia, diarrhea, fatigue, anemia, vomiting, alopecia, constipation, rash, decreased appetite, and abdominal pain. This article summarizes the FDA review process and data supporting the approval of sacituzumab govitecan.
