Enfortumab vedotin plus pembrolizumab has received Food and Drug Administration approval based on recent phase 3 trial data showing superior efficacy compared with first-line platinum-based chemotherapy; however, its distinct toxicity profile may make it less suitable for some patients, and availability in some countries may be limited by cost considerations. Consequently, platinum-based chemotherapy is expected to remain an important first-line treatment option. Choice of platinum regimen (cisplatin- or carboplatin-based) is informed by assessment of clinical characteristics, including performance status, kidney function, and presence of peripheral neuropathy or heart failure. For patients without disease progression after completing platinum-based chemotherapy, avelumab first-line maintenance treatment is recommended by international guidelines. For patients who have disease progression, pembrolizumab is the preferred approach. Additionally, following results from a recent phase 3 trial, nivolumab plus cisplatin-based chemotherapy has also received Food and Drug Administration approval and is an additional first-line treatment option for cisplatin-eligible patients. Later-line options for patients with advanced urothelial carcinoma, depending on prior treatment, may include enfortumab vedotin, erdafitinib (for patients with FGFR2/3 mutations or fusions/rearrangements), sacituzumab govitecan, and platinum rechallenge. For the small proportion of patients ineligible for any platinum-based chemotherapy (i.e., unsuitable for cisplatin or carboplatin), immune checkpoint inhibitor monotherapy with pembrolizumab or atezolizumab is a first-line treatment option, although approved agents vary between countries. In summary, this podcast discusses recent developments in the treatment landscape for advanced urothelial carcinoma, eligibility for platinum-based chemotherapy, potential first-line treatment options, and treatment sequencing.

The majority of these AEs (62%) were classified as moderate clinical priorities (e.g., interstitial lung disease with T-DXd, thrombocytopenia, peripheral neuropathy with T-DM1, febrile neutropenia, and large intestine perforation with SG). Three AEs emerged as high clinical priorities (6 points): septic shock and neutropenic colitis with SG (N = 8 and 13, with median onset 13 and 10 days, respectively), without co-reported immunosuppressive agents; and pulmonary embolism with T-DM1 (N = 31, median onset 109 days, 52% with reported metastasis).</p><p><strong>Conclusion: </strong>The heterogeneous spectrum of post-marketing toxicities for ADCs used in breast cancer, as emerging from the FAERS, is largely in line with preapproval evidence. Although causality cannot be proved, we call for increased awareness by oncologists on potential serious unexpected reactions, including early onset of septic shock and neutropenic colitis with SG, and late emergence of pulmonary embolism with T-DM1.</p>","PeriodicalId":22195,"journal":{"name":"Targeted Oncology","volume":" ","pages":"435-445"},"PeriodicalIF":5.4,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11111510/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140865377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
