These agents exert their anticancer effects against RCC by modulating multiple signaling pathways, including PI3K/AKT/mTOR, AMPK, JAK2/STAT3, ERK1/2, Wnt/β-catenin, and RhoA/ROCK, as well as by inducing autophagy inhibition, ferroptosis, oxidative stress, and mitochondrial dysfunction, highlighting their utility in RCC therapy and emphasizing their clinical relevance.</p>","PeriodicalId":9556,"journal":{"name":"Cancer Chemotherapy and Pharmacology","volume":"96 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148535091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data were primarily extracted from European Public Assessment Reports, supplemented with information from the Drugs@FDA database, ClinicalTrials.gov, and peer-reviewed mass balance study publications.</p><p><strong>Results: </strong>Mass balance studies were conducted for 68 out of the 69 PKIs listed as \"authorized\" human drugs in the European Medicines Agency database on July 7, 2025 (updated April 18, 2026; +3 PKIs). The studies included 2-12 participants (median = 6), with 90% enrolling only healthy volunteers, 88% enrolling only males, 97% administering a single dose, and four studies mentioning consideration of genetic variation in metabolic enzymes during participant inclusion.</p><p><strong>Conclusion: </strong>PKI mass balance studies exhibit similar, rather homogeneous design characteristics, potentially limiting the generalizability of their insights into drug metabolism across diverse patient populations. Still, most align with recent FDA guidelines on mass balance studies, despite being issued after study conduct.</p>","PeriodicalId":9556,"journal":{"name":"Cancer Chemotherapy and Pharmacology","volume":"96 1","pages":""},"PeriodicalIF":2.5,"publicationDate":"2026-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13364880/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148429832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
