Encouraging direction, but not yet definitive.
This meta-analysis pools single-arm data from four post-TKI, MET-selected NSCLC cohorts (n=338) to evaluate savolitinib plus osimertinib, reporting an ORR of 53.9% (95% CI 45.1–62.4%) and DCR of 85.2% (79.2–89.8%), with grade ≥3 adverse events in 48.8%. The authors acknowledge that reliance on single-arm evidence limits conclusions and call for randomized trials to confirm benefit.
Meta-analysis of randomized controlled trials and prospective single-arm studies. Patients with EGFR-mutant, MET-aberrant advanced NSCLC enrolled in included trials; primary analysis restricted to post-TKI, MET-selected cohorts.. Intervention: Savolitinib combined with osimertinib. n = 338.
Pooled ORR in post-TKI, MET-selected cohorts was 53.9% (95% CI: 45.1–62.4%) across 338 patients from 4 cohorts Disease control rate was 85.2% (95% CI: 79.2–89.8%) 6-month PFS rate was 59.8%
Grade ≥3 adverse events occurred in 48.8% of patients
Clinicians should view this as early supporting evidence for combined savolitinib and osimertinib in select MET-aberrant NSCLC patients, particularly those progressing on prior TKI therapy. However, the absence of a randomized control arm and reliance on surrogate endpoints (ORR, DCR) mean treatment decisions should await confirmatory randomized trial data before widespread adoption.
Meta-analysis of single-arm cohorts showing encouraging efficacy (ORR 53.9%) and manageable safety, but limited by lack of randomized comparator and reliance on surrogate endpoints; requires confirmatory RCT evidence.

Objectives: NSCLC is the leading cause of cancer-related mortality. While combined therapy including savolitinib and osimertinib appears promising, there exists a lack of comprehensive pooled evidence regarding its anti-oncological activity.: The objective of this study is to evaluate the efficacy and safety of combined therapy in patients with NSCLC. Methods: A comprehensive literature search was conducted in MEDLINE, the Cochrane Central Register of controlled trials, and ClinicalTrials.gov. Randomized controlled trials and prospective single-arm studies evaluating savolitinib combined with osimertinib were included. A random-effects single-arm meta-analysis of proportions was performed using logit transformation and inverse variance weighting, with restricted maximum likelihood (REML) estimation and Knapp-Hartung adjustment. Results were reported with a 95% CI, and heterogeneity was assessed using the I 2 statistic. Sensitivity analysis was conducted using the Freeman-Tukey transformation. Results: The primary analysis included 4 post-TKI, MET-selected combination cohorts (SACHI, SAVANNAH, and TATTON Part B; n=338) from 7 reports of 5 trials after de-duplication of overlapping data sets. First-line (FLOWERS) and MET-unselected (Yoh) cohorts were analyzed separately. The pooled objective response rate (ORR) was 53.9% (95% CI: 45.1-62.4), disease control rate (DCR) was 85.2% (79.2-89.8), 6-month progression-free survival (PFS) rate was 59.8%, and grade ≥3 adverse events occurred in 48.8% of patients. ORR estimates were consistent across studies and remained robust across sensitivity and subgroup analyses. Conclusions: Combined therapy shows encouraging results in selected MET, post-TKI NSCLC. However, reliance on single-arm data warrants further randomized controlled trials.
