The SACHI trial demonstrated that savolitinib plus osimertinib nearly doubled progression-free survival (PFS) compared with chemotherapy (9.8 vs. 5.4 months; hazard ratio 0.34) in patients with EGFR-mutated, MET-amplified non-small-cell lung cancer (NSCLC) after EGFR tyrosine kinase inhibitor (TKI) failure-the first phase 3 evidence for dual EGFR/MET inhibition in this setting.1.
Notably, one patient with acquired MET amplification achieved a renewed partial response to the combination of sotorasib and tepotinib after progression on sotorasib monotherapy. Our findings support rebiopsy at progression on sotorasib. Further prospective trials are warranted to validate MET amplification as a resistance mechanism and to define optimal therapeutic thresholds for combined KRAS and MET inhibition.

The zLiverMet model successfully mimics intrahepatic metastasis and highlights c-Met as a driver of liver tropism. This zebrafish-based model offers an 'organism-on-a-chip' platform that is rapid, imageable and scalable-bridging in vitro assays and in vivo models for mechanistic and therapeutic studies of liver metastasis.

While the primary end point of best ORR was not met in this nonrandomized clinical trial, amivantamab was well tolerated, and most patients exhibited disease stabilization. ClinicalTrials.gov Identifier: NCT05074940.
Although the tumour relapsed 4 months postoperatively, treatment with tepotinib resulted in a favourable response and subsequent pembrolizumab therapy achieved a durable response. This case suggests that patients with sarcomatoid carcinoma, which is generally associated with a poor prognosis, may experience improved outcomes with the use of molecular targeted therapies and immune checkpoint inhibitors.
