Primary end point was confirmed objective response rate (ORR) .  \nResults: In total, 113 patients were enrolled following a median of 3 (range 1–18) prior systemic regimens. Altered RET (n = 31), CBL (n = 31) and MET (n = 17) were most frequent cohorts. Overall, 68.9% had reduced tumor volume and most (61.5%) had a best objective response of stable disease. ORR was highest in patients with RET-rearranged non-small cell lung cancer (21.1%) but did not differ significantly from the null hypothesis (ORR ≤ 15%; p = 0.316) . Median progression-free survival and overall survival (5.7 and 24.2 months, respectively) were also longest in theRET-rearranged non-small cell lung cancer cohort. Diarrhea (61.1%), fatigue (50.4%) and hypertension (46.9%) were the most frequent treatment-emergent adverse events. Most treatment-emergent adverse events were mildto-moderate in severity. The study closed before the planned number of patients were enrolled in all cohorts.  \nConclusion: Sitravatinib had a manageable safety profile with modest signals of clinical activity inpatients with molecularly selected solid tumors.  \nClinical trial registration: [www.clinicaltrials.gov](www.clinicaltrials.gov) identifier is NCT02219711  \nPLAIN LANGUAGE SUMMARY  \nWe report findings from a clinical study of sitravatinib which included patients with cancer that could not be removed by surgery or had spread to other parts of the body. The tumors of these patients contained specific molecular changes in one of the following genes: MET, AXL, RET, NTRK, DDR2, KDR, PDGFRA, KITor CBL. All patients received treatment with sitravatinib once a day. Change in tumor size over time was assessed to see how effective treatment with sitravatinib was.  \nIn total, 113 patients joined the study. Most patients had already received a median of three different types of medicines for their cancer (and up to 18 different types of anticancer medicines) . Most patients had tumors that contained alterations in RET, CBL or MET genes.  \nDuring the study, the percentage of patients who had a decrease in the tumor size","cbCaihmkqEmJNObU","https://ap.wps.com/l/cbCaihmkqEmJNObU","pdf",1552664,15,"English","# Abstract\n## Aim\n## Materials & methods\n## Results\n## Conclusion","[{\"question\":\"What was the purpose of the Phase Ib study of sitravatinib?\",\"answer\":\"The study assessed clinical activity and safety of sitravatinib in patients with advanced cancer, using basket cohorts defined by specific molecular alterations.\"},{\"question\":\"Which patients were eligible and how was sitravatinib administered?\",\"answer\":\"Patients had advanced solid tumors with amplification, mutation, or rearrangement in specified genes (including MET, AXL, RET, NTRK, DDR2, KDR, PDGFRA, KIT, or CBL) and received sitravatinib once daily.\"},{\"question\":\"What were the main efficacy and safety findings?\",\"answer\":\"Overall, 68.9% had reduced tumor volume and most patients had stable disease.
