Trastuzumab rezetecan improved progression-free survival versus pyrotinib plus capecitabine and showed a distinct safety profile in patients with HER2-positive breast cancer, presenting as a potential new treatment option.
Overall, the available real-world evidence supports the clinical effectiveness of tucatinib-based therapies in HER2+ MBC, including heavily pretreated populations, patients with prior exposure to T-DXd, and those with brain metastases. However, gaps remain in the real-world data regarding the safety profile of tucatinib and its impact on health-related quality of life in routine clinical practice.
In the RATIONALE-305 trial, first-line tislelizumab + chemotherapy (CAPOX ([capecitabine + oxaliplatin] or 5-fluorouracil [5-FU] + cisplatin) significantly improved overall and progression-free survival (PFS) versus placebo + chemotherapy in unresectable or metastatic human epidermal growth factor receptor 2 (HER2)-negative gastric/gastroesophageal junction cancer (GC/GEJC). This exploratory analysis evaluated the comparative efficacy of tislelizumab + CAPOX versus tislelizumab + CAPOX or FOLFOX (5-FU, leucovorin, oxaliplatin) using a matching-adjusted indirect comparison (MAIC) approach...Although median PFS was numerically longer with the mixed chemotherapy backbone, these findings are exploratory in nature and warrant further investigation. ClinicalTrials.gov, RATIONALE-305 (NCT03777657); DisTinGuish (NCT04363801).
Overall, alpelisib combined with capecitabine demonstrated modest antitumor activity in a molecularly selected subset of patients with metastatic colorectal cancer. However, frequent treatment-limiting toxicities may limit the future clinical applicability of this regimen and highlight the need for improved toxicity management and optimized patient selection.
