This report contributes to the literature by providing evidence of selpercatinib’s potential as a treatment option in such refractory cases. The patients described in both cases were diagnosed with metastatic RET fusion-positive NSCLC and developed intracranial metastases during pralsetinib treatment. After switching to selpercatinib, both exhibited significant intracranial responses. The first patient reported a reduction in brain metastasis size and maintained a response for over 1.5 years. The second patient also responded intracranially to selpercatinib but unfortunately passed away 8 months later owing to pulmonary hemorrhage, possibly linked to prior radiation treatment. These cases highlight the potential efficacy of selpercatinib in treating intracranial metastases in RET fusion-positive patients with NSCLC after pralsetinib-refractory progression.

In clinically stable population with progressive disease (n = 247), survival after progression was 13.3 (95% CI: 10.9–16.4) months for those who continued osimertinib beyond progressive disease (n = 124), and 24.1 (95% CI: 17.7–34.0) months for those who discontinued osimertinib (n = 123) (hazard ratio = 2.01, 95% CI: 1.38–2.91, <em>p</em> = 0.0002). Platinum plus pemetrexed had the best overall survival benefits after osimertinib.</div></div><div><h3>Conclusions</h3><div>First-line osimertinib was found to have good effectiveness comparable to that reported in pivotal studies. Nevertheless, osimertinib should be discontinued among those who develop progression.</div></div><div><h3>Trial registration number</h3><div>UMIN000038683</div></div>","PeriodicalId":17675,"journal":{"name":"JTO Clinical and Research Reports","volume":"5 11","pages":"Article 100720"},"PeriodicalIF":3.0,"publicationDate":"2024-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142426750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
