….139 (76.8%) yielded a result and BRCA/ATM alterations were identified in 111 (79.9%). Of these, 73 patients received olaparib and 38 received control….rPFS was longer in the olaparib group versus control [median 7.4 vs. 3.5 months; hazard ratio (HR), 0.33; 95% confidence interval (CI), 0.21–0.53; nominal P < 0.0001], which is consistent with Cohort A ITT population (HR, 0.34; 95% CI, 0.25–0.47).

The top altered genes were TP53 (44%), ESR1 (37%), CDH1 (17%), FGFR1 (12%), NF1 (11%), CHEK2 (10%), and PTEN (9%). In pts treated with PBO+FUL, alterations in PTEN (HR 2.8; 95% CI 1.4-5.7; p=0.0107) and TP53 (HR 2.0; 95% CI 1.3-3.1; p=0.0025) were associated with a worse prognosis compared to pts with no mutation detected (NMD) in these genes. In pts treated with TAS+FUL, alterations in FGFR1 (HR 2.4; 95% CI 1.5-3.7; p=0.0006), TP53 (HR 1.9; 95% CI 1.4-2.6; p=0.0001) and PTEN (HR 1.8; 95% CI 1.1-2.8; p=0.0265) were associated with a worse prognosis compared to pts with NMD in these genes.We report that the most frequently mutated genes identified are consistent with previous studies in pts with ER+, HER2- aBC. This analysis shows that alterations in TP53 and PTEN were associated with poor prognosis in both tx arms, and FGFR1 alterations were associated with a poor prognosis in TAS+FUL treated pts. Further, NF1 alterations were associated with a poor prognosis in PBO+FUL treated pts, an association that was not observed with TAS+FUL.

Mobocertinib has shown efficacy in PPP with EGFR ex20ins NSCLC.

A liver tumor biopsy was performed, which confirmed ICC….liquid CGP (FoundationOne® Liquid CDx, Foundation Medicine) was performed, and FGFR2 fusion was detected....Two months after initiating pemigatinib, a CT scan showed controlled intrahepatic lesions and other distant metastases, and the state of the cancer was considered a stable disease based on RECIST...

...a case of a 65-year-old woman who was diagnosed with metastatic lung adenocarcinoma….Plasma genotyping revealed that the tumor harbored a MET exon 14 skipping mutation, and we started capmatinib, a selective MET inhibitor. The CNS lesions markedly decreased and the performance status of the patient dramatically improved.

...he was transitioned to oral osimertinib 80 mg daily in combination with oral savolitinib 300 mg daily under the clinical trial TATTON...he achieved partial response for 18 months before developing progressive disease (Fig. 1). Tissue biopsy confirmed adenocarcinoma, and next-generation sequencing of circulating tumor DNA (FoundationOne Liquid, Foundation Medicine) revealed EGFR-delL747_T751 mutation (allele frequency [AF] 3.3%), lack of EGFR-T790M and EGFR-C797S, MET amplification, and MET mutations (D1228H AF 15.6%, D1228N AF 1.8%, D1228Y AF 1.6%, and Y1230C AF 0.98%).

He was treated with oral erlotinib daily for 14 months before developing disease progression in his liver. Targeted biopsy revealed metastatic lung adenocarcinoma with EGFR-delL747_T751 (exon 19 deletion) and MET amplification (FoundationOne, Foundation Medicine).

Off-label oral cabozantinib 60 mg daily was added to oral osimertinib 80 mg daily in an effort to target these MET mutations (Table 1). Although he achieved stable disease (Fig. 1), he developed considerable fatigue, gastrointestinal toxicity, and cytopenias on dual-inhibitor therapy, thus requiring cessation of cabozantinib. A repeat liquid biopsy revealed the original truncal EGFR mutation, MET amplification, and the known MET-D1228X mutations (Fig. 1). He was continued on osimertinib but died after 3 months.
