Detailed Description
This study is a prospective, single arm, phase II clinical study. Patients with advanced solid tumors who had previously failed standard treatment and had FGFR1-3 alterations were selected and included in this study after signing the informed consent form and meeting the inclusion criteria. The patient will receive oral treatment with pemitinib (13.5 mg QD, administered for 2 weeks/discontinued for 1 week). Before assessment for eligibility, patients were prescreened centrally for FGF/FGFR status using massively parallel DNA sequencing.Patients who already had an FGF/FGFR status report based on local assessment (Clinical Laboratory Improvement Amendments [CLIA]-certifed) or an existing MTB approved report were also included. The subjects will continue treatment until disease progression or intolerable toxicity occurs. During the treatment process, clinical tumor imaging evaluation was conducted according to RECIST v1.1, every 6 weeks (± 7 days), and every 9 weeks (± 7 days) after 48 weeks. Use NCI-CTCAE 5.0 for safety assessment.
